110 PURPOSE AND SCOPE
111 Background
The National Flood Insurance Program (NFIP) provides federally backed flood insurance that
encourages communities to enact and enforce floodplain regulations. Since its inception in
1968, the program has been very successful in helping flood victims get back on their feet.
There are nearly 4.6 million policies in force, with about $2 billion in written premiums.
From 1978 through 2004, over 940,000 losses totaling almost $14 billion have been paid.
To be covered by a flood insurance policy, a property must be in a community that
participates in the NFIP. To qualify for the program, a community adopts and enforces a
floodplain management ordinance to regulate development in flood hazard areas. The basic
objective of the ordinance is to ensure that such development will not aggravate existing
flooding conditions and that new buildings will be protected from flood damage. Today, over
19,000 communities participate in the NFIP.
The NFIP has been successful in requiring new buildings to be protected from damage by a
100-year flood. However, flood damage still results from floods greater than the 100-year
flood and from flooding in unmapped areas. Under the Community Rating System (CRS),
there is an incentive for communities to do more than just regulate construction of new
buildings to minimum national standards. Under the CRS, flood insurance premiums are
adjusted to reflect community activities that reduce flood damage to existing buildings,
manage development in areas not mapped by the NFIP, protect new buildings beyond the
minimum NFIP protection level, help insurance agents obtain flood data, and help people
obtain flood insurance.
112 Goals
The goals of the National Flood Insurance Program (NFIP) are to provide flood
insurance to property owners, to encourage flood loss reduction activities by
communities, and to save taxpayers’ money. The CRS is a part of the NFIP and
provides both incentives and tools to further these goals.
The goals of the CRS are to recognize, encourage, and reward, by the use of flood
insurance premium adjustments, community and state activities beyond the minimum
required by the NFIP that
● Reduce flood damage to insurable property,
● Strengthen and support the insurance aspects of the NFIP, and
● Encourage a comprehensive approach to floodplain management.
CRS Coordinator’s Manual
110-1
Edition: July 2007
Purpose and Scope
The objective of the CRS is to support the goals of the NFIP. To do this, the CRS provides
insurance premium rate reductions to policy holders in recognition that their communities
implement activities that work toward its three goals of reducing flood damage, supporting
the insurance part of the NFIP, and pursuing a broad approach to floodplain management.
In this process, the “community” part of the Community Rating System includes state and
regional agencies and private organizations that support and assist city, county, and tribal
governments that are participants in the NFIP. A closer look at how communities can
implement these three goals follows.
1. Reduce flood damage to insurable property. Communities are encouraged to map
and provide regulatory flood data for all their flood hazards. The data should be used
in their regulatory programs and shared with all users and inquirers. New buildings in
mapped floodplains should be protected from the known local flood hazards, which
may require setting standards higher than the minimum national criteria of the NFIP.
Communities are encouraged to reduce the exposure of existing buildings to flood
damage, especially repetitive loss properties.
2. Strengthen and support the insurance aspects of the NFIP. Communities should
encourage their residents to be aware of their flood risk and to purchase and maintain
a flood insurance policy to protect themselves from the financial impacts of flooding.
Communities should also help make the program more financially sound by
implementing mapping and information programs that help to evaluate accurately the
individual property risk for flood insurance rating purposes, expand the policy base,
and reduce repetitive losses.
3. Encourage a comprehensive approach to floodplain management. Insurable
property is not the only floodplain management concern of communities, so the CRS
recognizes efforts that protect lives; further public health, safety, and welfare; and
protect natural floodplain functions. The community staff should understand the
physical and biological processes that form and change floodplains and watersheds
and take steps to deal with flooding, erosion, habitat loss, water quality, and special
flood-related hazards. Floodplain management programs need to protect buildings,
infrastructure, critical facilities, and natural functions and ensure that new
development does not cause adverse impacts on others. A comprehensive approach
uses all tools, including public information, planning, regulatory authorities, financial
support, public works activities, and emergency management.
CRS Coordinator’s Manual
110-2
Edition: July 2007
Purpose and Scope
113 Operation
To be recognized in the insurance rating system, community floodplain management activities must be described, measured, and evaluated. The basic tool for this is the CRS Schedule,
which sets forth the application procedures, creditable activities, and the credit points
assigned to each activity. A community receives a CRS classification based upon the total
score for its activities. The CRS Commentary explains the Schedule and gives examples of
activities and how their credit is calculated. The Schedule and Commentary are included
within the CRS Coordinator’s Manual, the primary document detailing the program.
There are 10 CRS classes: Class 1 requires the most credit points and gives the greatest
premium reduction; Class 10 receives no premium reduction. A community that does not
apply for the CRS, or does not obtain the minimum number of credit points, is a Class 10
community.
Community participation in the CRS is voluntary. Any community in full compliance with the
rules and regulations of the NFIP may apply for a CRS classification better than Class 10.
The applicant community submits the CRS Application along with documentation which
shows that it is implementing the activities for which credit is requested. All CRS credit is
verified according to the detailed discussion of the activities in the Coordinator’s Manual.
The application process is discussed in more detail in the CRS Application.
The Schedule identifies 18 creditable activities, organized under four categories labeled
Sections 300 through 600: Public Information, Mapping and Regulations, Flood Damage
Reduction, and Flood Preparedness. The Schedule assigns credit points based upon the extent
to which an activity advances the three goals of the CRS. Communities are invited to propose
alternative approaches to these activities in their applications.
Some CRS activities may be implemented by the state or a regional agency rather than at the
community level. For example, some states have disclosure laws that are creditable under
Activity 340 (Flood Hazard Disclosure). Any community in those states will receive those
credit points when it applies for CRS credit and demonstrates that the law is effectively
implemented within its jurisdiction.
An application for a CRS classification may be submitted at any time. A community applies
by sending a completed CRS Application with appropriate documentation to its ISO/CRS
Specialist. Copies of all or parts of the application may be sent to the Regional Office of the
Department of Homeland Security’s Federal Emergency Management Agency (FEMA) and to
the State NFIP Coordinator.
The Insurance Services Office, Inc. (ISO) is subscribed to by more than 1,300 insurance
companies. Among other services, ISO develops and provides advisory fire insurance
classifications for community fire protection programs. ISO reviews CRS applications,
verifies the communities’ credit points, and performs program improvement tasks.
The community’s activities and performance are reviewed during a verification visit. FEMA
sets the credit to be granted and notifies the community, the state, insurance companies, and
CRS Coordinator’s Manual
110-3
Edition: July 2007
Purpose and Scope
other appropriate parties. The classification is effective on either May 1 or October 1,
whichever comes first after the community’s program is verified.
Each year the community must recertify or reverify that it is continuing to perform the
activities that are being credited by the CRS. Recertification is an annual activity that
includes progress reports for certain activities. The cycle verification takes place every few
years and is conducted in the form of another verification visit to the community.
If a community is not properly or fully implementing the credited activities, its credit points,
and possibly its CRS classification, will be revised. A community may add credited activities
each year in order to improve its CRS classification.
Credit criteria will change over time as experience is gained in implementing, observing, and
measuring the activities and as new concepts in floodplain management come into common
practice. As innovations arise, they will be considered for recognition under the CRS.
Communities are encouraged to call on their ISO/CRS Specialist for assistance at any time. A
week-long CRS course for local officials is offered free at FEMA’s Emergency Management
Institute. The ISO/CRS Specialist, State NFIP Coordinator, and FEMA Regional Office have
more information on this course, state workshops, and other CRS training opportunities.
114 Community Responsibilities
Once it has submitted its CRS Application, a community must continue to implement its
credited activities to keep its classification. Specifically, a community is responsible for:
•
Designating someone who is familiar with the agencies that implement CRS activities
as the community’s CRS Coordinator,
•
Cooperating with the ISO/CRS Specialist and the verification procedures (Section
230),
•
Recertifying each year that it is continuing to implement its activities (Section 214),
•
Submitting the appropriate documents with its recertification (Section 214),
•
Advising FEMA and its ISO/CRS Specialist of modifications in its activities (Section
215),
•
Maintaining elevation certificates, other permit records, and old Flood Insurance Rate
Maps (FIRMs) forever,
•
Maintaining other records of its activities for five years, or until the next verification
visit, whichever comes sooner, and
•
Participating in the cycle verification process (Section 234).
CRS Coordinator’s Manual
110-4
Edition: July 2007
Purpose and Scope
Communities will receive periodic updates to the Coordinator’s Manual and other CRS
materials. They are encouraged to order the background publications (see Appendix E),
attend CRS workshops, and ask their ISO/CRS Specialists for help understanding the CRS
credit criteria for their current and planned activities.
115 Costs and Benefits
Communities should prepare and implement those activities which best deal with their local
problems, whether or not they are creditable under the CRS. Few, if any, of the CRS activities
will produce premium reductions equal to or in excess of their implementation costs. In
considering whether to undertake a new floodplain management activity, a community must
consider all of the benefits the activity will provide (not just insurance premium reductions)
in order to determine whether it is worth implementing.
a. Costs
No fee is charged for a community to apply for participation in the CRS. The only costs the
community incurs are those of implementing creditable floodplain management activities and
the staff time needed to prepare the CRS Application.
b. Benefits
It is important to note that reduced flood insurance rates are only one of the rewards a
community receives from participating in the CRS. There are several other benefits.
First, the CRS floodplain management activities provide enhanced public safety, a reduction
in damage to property and public infrastructure, avoidance of economic disruption and losses,
reduction of human suffering, and protection of the environment.
Second, through the CRS a community can evaluate the effectiveness of its flood program
against a nationally recognized benchmark.
Third, technical assistance in designing and implementing some activities is available through
the CRS at no charge.
Fourth, a CRS community’s flood program benefits from having an added incentive to
maintain its flood programs over the years. The fact that the community’s CRS status could
be affected by the elimination of a flood-related activity or a weakening of the regulatory
requirements for new development, should be taken into account by the governing board
when considering such actions. A similar system used in fire insurance rating has had a
strong impact on the level of support local governments give to their fire protection
programs.
Fifth, implementing some CRS activities, such as floodplain management planning, can help
a community qualify for certain federal assistance programs.
CRS Coordinator’s Manual
110-5
Edition: July 2007
Purpose and Scope
116 Natural and Beneficial Functions
Floodplains perform certain natural and beneficial functions that cannot be duplicated
elsewhere. The CRS provides special credit for community activities that protect these
functions, even though some of the activities may not directly reduce flood losses to insurable
buildings. Two types of “natural and beneficial functions” warrant protecting floodplains in
their natural state.
1. Floodplains in their natural state have an important impact on flooding. Flood waters
can spread over a large area in floodplains that have not been encroached upon. This
reduces flood velocities and provides flood storage to reduce peak flows downstream.
Natural floodplains reduce wind and wave impacts and their vegetation stabilizes soils
during flooding.
2. Floodplains in their natural state provide “ancillary beneficial functions” beyond flood
reduction. Water quality is improved in areas where natural cover acts as a filter for
runoff and overbank flows; sediment loads and impurities are also minimized. Natural
floodplains moderate water temperature, reducing the possibility of adverse impacts
on aquatic plants and animals.
Floodplains can act as recharge areas for groundwater and reduce the frequency and
duration of low flows of surface water. They provide habitat for diverse species of
flora and fauna, some of which cannot live anywhere else. They are particularly
important as breeding and feeding areas.
The CRS encourages state, local, and private programs and projects that preserve or restore
the natural state of floodplains and protect these functions. The CRS also encourages
communities to coordinate their flood loss reduction programs with Habitat Conservation
Plans and other public and private activities that preserve and protect natural and beneficial
floodplain functions. Credits for doing this are found in the following activities:
330 Outreach Projects: Credit is provided for outreach projects that include descriptions of
the natural and beneficial floodplain functions of the community’s floodplains.
420 Open Space Preservation: Extra credit is provided for open space areas that are
preserved in their natural state, have been restored to a condition approximating their predevelopment natural state, or have been designated as worthy of preservation for their natural
benefits, such as being designated in a Habitat Conservation Plan.
430 Higher Regulatory Standards: Regulations that protect natural areas during development
or that protect water quality are credited.
450 Stormwater Management: Erosion and sediment control and water quality requirements
for projects that affect stormwater runoff are credited.
CRS Coordinator’s Manual
110-6
Edition: July 2007
Purpose and Scope
510 Floodplain Management Planning: Extra credit is provided for plans that address
floodplain natural resources and that are coordinated with a community’s Habitat Conservation Plan.
117 CRS Activities
The CRS Schedule describes the 18 floodplain management activities credited by the CRS and
the documentation required to receive credit for each activity. The credits and formulae used
to calculate credit are also included. These activities are divided into four categories.
Public Information (Series 300)
This series credits programs that advise people about the flood hazard, flood
insurance, and ways to reduce flood damage. These activities also provide data needed
by insurance agents for accurate flood insurance rating. They generally serve all
members of the community and work toward all three goals of the CRS.
Mapping and Regulations (Series 400)
This series credits programs that provide increased protection to new development.
These activities include mapping areas not shown on the FIRM, preserving open
space, enforcing higher regulatory standards, and managing stormwater. The credit is
increased for growing communities. These activities work toward the first and second
goals of the CRS, damage reduction and accurate insurance rating.
Flood Damage Reduction (Series 500)
This series credits programs for areas in which existing development is at risk. Credit
is provided for a comprehensive floodplain management plan, relocating or retrofitting
floodprone structures, and maintaining drainage systems. These activities work toward
the first goal of the CRS, damage reduction.
Flood Preparedness (Series 600)
This series credits flood warning, levee safety, and dam safety programs. These
activities work toward the first and third goals of the CRS, damage reduction and
hazard awareness.
NOTE: The CRS encourages communities to develop and implement locally pertinent
programs that exceed the minimum criteria of the NFIP. It is the intent of the CRS to credit
only those activities that are compliant with applicable federal, state, and local
environmental laws and regulations, including the Endangered Species Act of 1973. Where
this is an issue, it is the responsibility of the community to demonstrate that an activity
complies with those laws or regulations.
CRS Coordinator’s Manual
110-7
Edition: July 2007
Purpose and Scope
The CRS activities are not design standards for local floodplain management. The Schedule is
an insurance tool that describes methods of calculating credit points for various community
activities. The fact that the CRS does not provide a direct credit for some activities does not
mean that they should not be implemented by communities that need them.
Some activities and elements are not directly recognized by the CRS for one of three reasons:
1. They do not directly impact buildings that can be insured under the NFIP (e.g.,
uninsurable items such as streets and land values);
2. They are recognized by other aspects of the flood insurance rating program (e.g., flood
control projects that result in revised FIRMs reduce flood insurance premiums in
protected areas); or
3. The impact of an activity cannot be measured for CRS credit (e.g., preserving
floodplains for aesthetic reasons).
118 Uniform Minimum Credit
Many communities can qualify for “uniform minimum credit” whereby a state or regional
agency can apply for a CRS activity that it is implementing on behalf of its communities. For
example, several Florida water management districts enforce their own stormwater
management regulations. A community in one of those districts that applies to the CRS will
qualify for its district’s stormwater management credit.
If the community has its own program that deserves more credit points, it may apply for more
than the uniform minimum credit points. This approach saves time and money for everyone
involved. Agencies or communities interested in uniform minimum credits should contact
their FEMA Regional Office or ISO/CRS Specialist for more information (see Appendix A).
119 All-Hazard Mitigation
Communities with flood problems are also likely to be threatened by other natural and
technological hazards. The staff and programs that address flooding may also be responsible
for protecting the community from earthquakes, hurricanes, landslides, drought, hazardous
materials incidents, and terrorism. Similarly, staff that work in programs related to other
hazards may be implementing activities that could support floodplain management programs.
FEMA supports an all-hazards approach to mitigation, as does the CRS. It makes economic
sense that mitigation programs address as many hazards as are appropriate. An all-hazards
approach also ensures that staff, programs, construction standards, and public information
messages are consistent and mutually supportive.
The CRS has become an important tool for mitigation as well as a mechanism for integrating
mitigation with flood insurance. This is consistent not only with grading systems that have
CRS Coordinator’s Manual
110-8
Edition: July 2007
Purpose and Scope
been successfully employed for many years in the insurance industry, but also with new
industry initiatives for relating insurance premiums to local community efforts to reduce
losses due to natural hazards. For example, adoption and enforcement of strong building
codes as measured by the insurance industry’s Building Code Effectiveness Grading Schedule
integrates building code enforcement into the industry’s premium rates.
The CRS has served as a model for all-hazards pre-disaster mitigation activities. Several local
officials have reported that the CRS was the blueprint for organizing their program to build a
more disaster-resistant community.
The 2006 edition of the CRS Coordinator’s Manual highlights many opportunities for
expanding a flood-only orientation to address other hazards. These include:
•
The 300 series of public information activities credits advising people about the risk
of flooding and other hazards and the mitigation measures they can take to protect
their properties;
•
Under Activity 340 (Hazard Disclosure), disclosure of other hazards (DOH) credits
advising potential purchasers of property that there may be other hazards that could
affect the property, such as erosion, subsidence, or wetlands;
•
The credit for placing references in the public library under Activity 350 (Flood
Protection Assistance) includes extra points for including documents on special
flood-related hazards such as subsidence and coastal erosion;
•
Section 401 has an overview of the additional credits that are provided for mapping
and managing seven special hazards:
▫
Uncertain flow paths (alluvial fans, moveable bed streams, and other
floodplains within which the channel moves during a flood),
▫
Closed basin lakes,
▫
Ice jams,
▫
Land subsidence,
▫
Mudflow hazards,
▫
Coastal erosion, and
▫
Tsunamis.
•
Activity 420 (Open Space Preservation) encourages communities to keep hazardous
areas open and undeveloped;
•
Credit is provided for the International Series of building codes (which have
improved protection standards for flooding, wind, and other hazards over previous
model codes) in Activity 430 (Higher Regulatory Standards), Section 431.m;
•
Activity 430 (Higher Regulatory Standards) also credits extending V-Zone standards
for coastal storm surge and wind protection farther inland to include coastal A Zones
(Section 431.p);
CRS Coordinator’s Manual
110-9
Edition: July 2007
Purpose and Scope
•
Section 430LD (Land Development Criteria) increases the credit for land use and
development regulations in areas of mapped special hazards;
•
In Activity 440 (Flood Data Maintenance), additional credit is provided for showing
areas subject to other natural hazards in the GIS or database management program;
•
More credit points are available for including other hazards in a mitigation plan that
qualifies for a floodplain management plan under Activity 510 (Floodplain
Management Planning); and
•
Local warning and public information activities directed toward storms and tsunamis
are credited under the StormReady and TsunamiReady element in Activity 610
(Flood Warning Program).
CRS Coordinator’s Manual
110-10
Edition: July 2007
130 GLOSSARY
Unless otherwise noted, all terms used by the Community Rating System (CRS) are the same
as those defined in the National Flood Insurance Program Rules and Regulations (44 CFR
59.1).
A Zone: See “Zone A.”
Activity: A floodplain management activity for which Community Rating System credit has
been established.
Allowable surcharge: The acceptable limit of increased flood elevation in the floodway due
to obstruction of the floodway fringe.
Alluvial fan: An area at the base of a valley where the slope flattens out, allowing the
floodwater to decrease in speed and spread out, dropping sediment over a fan-shaped area.
The Community Rating System credits alluvial fan flooding under the “uncertain flow paths”
hazard in a special CRS publication.
B Zone: See “Zone B.”
Base flood: The flood having a 1% chance of being equaled or exceeded in any given year,
also known as the “100-year” or “1% chance” flood. The base flood is a statistical concept
used to ensure that all properties subject to the National Flood Insurance Program are
protected to the same degree against flooding.
BFE: Base flood elevation. The elevation of the crest of the base or 100-year flood.
Building: As used by the Community Rating System, the term is the same as “structure” in
the National Flood Insurance Program regulations (44 CFR 59.1). For CRS purposes, a
building is a structure that is walled and roofed, principally above ground and permanently
affixed to a site. The term includes a manufactured (mobile) home on a permanent foundation
(such as a poured masonry slab, foundation walls, piers, or block supports) so that no weight
is carried by the wheels and axles. “Walled and roofed” means that a building has two or
more rigid exterior walls in place and is adequately anchored so that it will resist flotation,
collapse, and lateral movement. “Principally above ground” means that at least 51% of the
actual cash value of the building, including equipment and machinery that are part of the
building, is above ground. The NFIP only insures “buildings.” For the purpose of counting
buildings for adjusting CRS credit points, the term “building” does not include accessory
structures. For example, a lot with a home, garage, and shed is counted as one building.
C Zone: See “Zone C.”
CBRA: The Coastal Barrier Resources Act of 1982 (pronounced “cobra”).
CEO: The Chief Executive Officer of a community, i.e., the official who is charged with the
authority to implement and administer laws, ordinances, and regulations for the community.
The CEO may be a mayor, city or county manager, or chair of a county board.
CRS Coordinator’s Manual
130-1
Edition: July 2007
Coastal: Relating to the coastlines and bays of the tidal waters of the United States or the
shorelines of the Great Lakes. Under the Community Rating System, there are four coastal
areas eligible for creditable coastal activities: the coastlines and bays of the Atlantic, Pacific,
Gulf of Mexico, and Great Lakes coasts. The term does not include riverine areas.
Coastal A Zone: Those parts of a community’s coastal floodplain, inland from the mapped V
Zone (or shoreline if there is no mapped V Zone), that are subject to the damaging effects of
waves, velocity flows, erosion, scour, or combinations of these forces. The exact boundary of
a coastal A Zone is determined by the community, as described in Section 431.p, although the
Federal Emergency Management Agency may provide a proposed boundary or “limit of
moderate wave action” on Flood Insurance Rate Maps.
Coastal Barrier Resources System: A set of “undeveloped coastal barriers” and “otherwise
protected areas” along the U.S. coast (including the Great Lakes) designated by Congress
under the Coastal Barrier Resources Act of 1982 (CBRA). Most expenditures of federal funds
are prohibited within the Coastal Barrier Resources System.
Coastal erosion: Coastal erosion is the wearing away of land masses caused primarily by
waves on the two oceans, the Gulf of Mexico, or the Great Lakes, and major embayments to
these bodies of water.
Coastal erosion-prone area: The coastal areas within which waves are anticipated to cause
significant erosion and shoreline retreat within the next 60 years.
Coastal high hazard flooding: A condition of flooding subject to high velocity waters,
including, but not limited to, hurricane wave wash or tsunamis. Coastal high hazard flooding
is mapped as a Zone V on a Flood Insurance Rate Map. Coastal flooding without the high
velocity hazard is mapped as a Zone A.
Community: A city, village, town, county, township, Indian tribe or authorized tribal
organization, Alaska Native village or authorized native organization, or other local
government with the statutory authority to enact floodplain regulations and participate in the
National Flood Insurance Program.
Contour: A line of equal elevation on a topographic (contour) map.
Critical facilities:
•
Structures or facilities that produce, use, or store highly volatile, flammable, explosive, toxic and/or water-reactive materials;
•
Hospitals, nursing homes, and housing likely to contain occupants who may not be
sufficiently mobile to avoid death or injury during a flood;
•
Police stations, fire stations, vehicle and equipment storage facilities, and emergency
operations centers that are needed for flood response activities before, during, and
after a flood; and
•
Public and private utility facilities that are vital to maintaining or restoring normal
services to flooded areas before, during, and after a flood.
CRS: Community Rating System.
CRS Coordinator’s Manual

Glossary
CRS Application: The publication that is generally used by a community to apply for its
initial Community Rating System classification. This publication includes a description of the
CRS activities, application procedures, and the documentation the community needs to
provide with its application.
CRS classification: A rating of a community’s floodplain management program according to
the CRS Schedule. The premium rate credits for each class are listed in Appendix C. A
community that has not applied for Community Rating System classification is a Class 10
community.
CRS Commentary: The portion of the CRS Coordinator’s Manual that explains the
Community Rating System in more detail than the CRS Schedule. It includes instructions on
how to apply for a CRS classification, along with references on and examples of the
creditable activities.
CRS Coordinator: A local official designated by the community’s Chief Executive Officer
to coordinate the community’s Community Rating System application and verification.
CRS Coordinator’s Manual: A publication for local officials that includes the Community
Rating System CRS Schedule, CRS Commentary, and activity worksheets. It is available from
FEMA or ISO.
CRS Schedule: The portion of the CRS Coordinator’s Manual that describes the Community
Rating System and how credit points are calculated to determine a community’s CRS
classification.
Cycle: A periodic review, scoring, and verification of a community’s Community Rating
System activities, normally done on a 3- or 5-year cycle.
D Zone: See “Zone D.”
Datum: A reference surface used to ensure that all elevation records are properly related.
Many communities have their own datum, developed before there was a national standard.
The National Flood Insurance Program uses the National Geodetic Vertical Datum (NGVD)
of 1929 and the North American Vertical Datum (NAVD) of 1988, which are in relation to
sea level. The Flood Insurance Rate Map indicates the datum that applies to the community.
Development: Any human-caused change to improved or unimproved real estate including,
but not limited to, buildings or other structures, mining, dredging, filling, grading, paving,
excavation, or drilling operations.
Discharge: The amount of water that passes a point in a given period of time. Rate of
discharge is usually measured in cubic feet per second (cfs).
Element: A discrete piece of a floodplain management program that is credited as part of a
Community Rating System activity.
CRS Coordinator’s Manual

Edition: July 2007
Glossary
FEMA: The Department of Homeland Security’s Federal Emergency Management Agency.
Most of the National Flood Insurance Program field work and community coordination is
done by the 10 FEMA Regional Offices, which are listed in Appendix A.
FIRM: Flood Insurance Rate Map. An official map of a community, on which FEMA has
delineated both the Special Flood Hazard Areas and the risk premium zones applicable to the
community. Most FIRMs include detailed floodplain mapping for some or all of a community’s floodplains. In most cases, the date of the first FIRM issued to a community is the date
the community entered the Regular Program of the National Flood Insurance Program.
Flood Insurance Study: A report published by FEMA for a community in conjunction with
the community’s Flood Insurance Rate Map. The study contains such background data as the
base flood discharges and water surface elevations that were used to prepare the FIRM. In
most cases, a community FIRM with detailed mapping will have a corresponding flood
insurance study.
Floodplain: Any land area susceptible to being inundated by flood waters from any source.
A Flood Insurance Rate Map identifies most, but not necessarily all, of a community’s
floodplain as the Special Flood Hazard Area.
Floodproofing: Protective measures added to or incorporated in a building that is not
elevated above the base flood elevation to prevent or minimize flood damage. “Dry
floodproofing” measures are designed to keep water from entering a building. “Wet
floodproofing” measures minimize damage to a structure and its contents from water that is
allowed into a building.
Floodway: The channel of a river and the portion of the overbank floodplain that carries
most of the base flood. The floodway must be kept open so that floods can proceed
downstream and not be obstructed or diverted onto other properties. The National Flood
Insurance Program regulations allow construction in the floodway provided that it does not
obstruct flood flows or increase flood heights.
Flood fringe: The portion of the floodplain lying on either side of the floodway.
Freeboard: A margin of safety added to the base flood elevation to account for waves,
debris, miscalculations, or lack of data.
Hydrology: The science dealing with the waters of the earth. A flood discharge is developed
by a hydrologic study.

310 ELEVATION CERTIFICATES
Summary of Activity 310
311 Credit Points. There are five elements in this activity for a maximum of 162 points.
a. Maintaining elevation certificates (EC): Up to 56 points are provided for maintaining FEMA elevation
certificates on all buildings built in the Special Flood Hazard Area (SFHA) after the date of application to the
CRS. All communities applying to the CRS must apply for this element. The community must make copies of
the certificates available to all inquirers. The FEMA elevation certificate is shown in Figure 310-2.
b. Maintaining elevation certificates for post-FIRM buildings (ECPO): Up to 56 points are provided for
maintaining elevation certificates on buildings built before the date of application to the CRS but after the initial
date of the Flood Insurance Rate Map (FIRM).
c. Maintaining elevation certificates for pre-FIRM buildings (ECPR): Up to 15 points are provided for
maintaining elevation certificates on buildings built before the initial date of the FIRM.
d. Maintaining elevation certificates in computer format (ECCF): Up to 15 points are provided if the elevation
certificate data are kept and made available in computer format. A free elevation certificate computer program
may be ordered (see Appendix E).
e. Maintaining elevation certificate data on a website (ECWS): Up to 20 points are provided for putting elevation
certificate data on a publicly accessible website.
f. Having off-site record storage (ORS): Up to 10 points are provided for keeping all elevation certifications,
regulations, plans, and other records in a secure area away from the permit office.
312 Impact Adjustment. The credit points for the last four elements are adjusted in one of three ways. There
is no impact adjustment for EC.
a. Under Option 1, where there are elevation certificates on all buildings that could have them, the impact
adjustment ratio is 1.0.
b. Under Option 2, where there are elevation certificates on at least 25% of all buildings that could have them, the
impact adjustment ratio is 0.25.
c. Under Option 3, the impact adjustment ratios reflect the proportion of buildings that have elevation certificates.
313 Credit Calculation. The credit points for each element are multiplied by the impact adjustment ratios.
314 Credit Documentation. The community must have the following available to verify implementation of
this activity:
a. [If applying for ECPO or ECPR and the community used a form different from FEMA’s] A copy of the
elevation certificate form and documentation that FEMA has approved the community’s form.
b. [If applying for ECCF credit] A copy of the computer format (if it is different from the software listed in
Appendix E).
c. Copies of all completed elevation certificates that the community wants credited for EC, ECPR, or ECPO.
Sample copies of the digital or website versions will be collected to document credit for ECCF and ECWS.
d. [If applying for ECWS credit] The website address.
e. Documentation showing how the impact adjustments were determined and how the community maintains,
stores, and provides copies of elevation certificates.
The community must submit the following with its annual CRS recertification.
f. [If applying for ECCF credit] A disk with the previous year’s elevation certificate data.

Elevation Certificates
310 ELEVATION CERTIFICATES
Background: According to insurance agents, one of the greatest impediments to
selling flood insurance is the difficulty of obtaining accurate flood insurance rating zone
and building elevation data. All of the technical data an agent needs should be
recorded on the Department of Homeland Security’s Federal Emergency Management
Agency (FEMA) elevation certificate. The National Flood Insurance Program (NFIP)
requires communities to maintain records of the elevations of new buildings and
substantial improvements, but not necessarily on FEMA’s forms.
The NFIP requirement for maintaining a record of the elevation of the lowest floor of any
new building or substantial improvement built in the Special Flood Hazard Area (SFHA) is
described in the Code of Federal Regulations (44 CFR 60.3(b)(5)(iii)). It states that the
community must “maintain a record,” but it does not specify a format for the record. Many
communities already use FEMA elevation certificates. The latest version of FEMA’s form
and instructions for it are shown in Figures 310-2a through n.
In 44 CFR 59.22(a)(9)(iii), the NFIP also requires that communities make their elevation and
related building information available for public inspection and flood insurance rating.
Because the NFIP does require insurance agents to use the FEMA form, their jobs are much
easier when that form is readily available from the local building department. The
information supplied with flood insurance applications is usually more accurate when the
form is prepared at the time of construction by someone familiar with the NFIP.
Use of the FEMA form also serves as a reminder to the local building officials of their
obligations to the NFIP and of the availability of flood insurance. Therefore, this activity
works toward all three Community Rating System (CRS) goals: reducing flood losses,
facilitating accurate flood insurance rating, and promoting the awareness of flood insurance.
Almost all buildings built to meet NFIP criteria are raised so the lowest floor is at or above
the base flood elevation, but some non-residential buildings are floodproofed. The NFIP rules
(44 CFR 60.3(c)(4)(ii)) require the community to keep floodproofing records. An example of
the latest version of FEMA’s floodproofing certificate (FEMA Form 81-65) is shown in
Figure 310-3.
Communities that have received a residential basement floodproofing exception must use
FEMA’s residential basement floodproofing certificate (FEMA Form 81-78) where
applicable. An example of this form and the communities approved to use it are included in
Figures 310-4 and 310-5, respectively.
Activity Description: Credit is provided if the community maintains FEMA elevation
certificates for new and substantially improved construction. To participate in the CRS,
a community must maintain completed FEMA elevation certificates on all buildings con-
CRS Coordinator’s Manual
310-2
Edition: July 2007
Elevation Certificates
structed, substantially improved, or placed in the SFHA after its initial date of
application for the CRS. The community must agree to use the certificate and make
copies available to any inquirer. All discussions about elevation certificates also apply
to FEMA’s floodproofing certificate and the residential basement floodproofing
certificate.
Copies of the FEMA elevation and floodproofing certificates are available free in quantity
from FEMA (see Section 315) and can be downloaded from FEMA’s website at
http://www.fema.gov/nfip/elvinst.shtm . Instructions are included with the forms.
Only the current FEMA form is acceptable. Local versions are no longer recognized for
elevation certificates that were completed after October 1, 2000. A community may receive
credit by transferring data from other forms onto a FEMA elevation certificate.
To receive a CRS classification, the community must start using the forms when it applies; so
forms need to be kept only for buildings built or substantially improved after that date. Credit
is also provided if the community had been using the forms since it joined the Regular
Program or if it transferred post-FIRM building elevation data to the forms. Additional credit
is awarded if the community provides certificates for pre-FIRM buildings or maintains the
data in a computer format.
THE MINIMUM REQUIREMENT FOR THIS ACTIVITY IS THAT THE COMMUNITY MAINTAIN
CERTIFICATES ON ALL NEW SFHA BUILDINGS AND SUBSTANTIAL IMPROVEMENTS PERMITTED
AFTER THE COMMUNITY APPLIES FOR CRS CREDIT . Because the community’s Chief Executive
Officer (CEO) certifies in the application that it is doing this, the community will receive up
to 56 points for EC (Elevation Certificates) under Section 311.a.
Those few NFIP communities which have no SFHA may not receive credit for this
activity. Instead, the CEO must certify that the community has no SFHA and is
therefore not applying for credit for this activity.
If a community with no SFHA is participating in the CRS and later receives a FIRM
from FEMA that includes areas of SFHA, it must begin maintaining elevation
certificates on the date of the FIRM or it will lose its CRS classification.
A community that has no SFHA at the time of its CRS application but later receives a FIRM
and begins maintaining elevation certificates will receive credit for EC. It also may receive
credit for maintaining post-FIRM elevation certificates (ECPO).
This activity is a minimum requirement for participation in the CRS. A verified EC score
of 45 points or more is necessary to meet this requirement. If the verified score is less
than 45, the CEO will be advised that the community will remain a Class 10.
CRS Coordinator’s Manual

Edition: July 2007
Elevation Certificates
During the community verification visit, the ISO/CRS Specialist will review a sample of
elevation certificates as explained in Section 232. If the ISO/CRS Specialist finds that the
community has not been maintaining the forms or has not been making copies available, the
value for the element EC (Section 311.a) will be zero. If the ISO/CRS Specialist finds that
some forms are not completed correctly, the points will be reduced. A verified score of less
than 45 for EC will result in no credit for this activity. If the community does not receive any
credit for this activity, it will remain a Class 10.
311 Credit Points
Maximum credit for Activity 310: 162 points.
Prerequisites: Credit for all elements in this activity is dependent on the following:
1. The community must maintain completed elevation certificates showing the
“finished construction” elevations for all buildings constructed or substantially
improved in the SFHA during the period credited;
2. The community must review the elevation certificates to ensure that the
information is correct; and
3. The community must make copies of elevation certificates readily available to
the property owners, their agents, and FEMA.
These three criteria must be met to receive full credit for each of the four elements. It is also
recommended that a community publicize the availability of elevation certificates.
The community should develop procedures to ensure that the data are correct for each site.
During the verification visit, the ISO/CRS Specialist will check for the following items on a
sample of elevation certificates.
SECTION A–PROPERTY INFORMATION
A 2. and A3. Complete street address or property description. In either case, the city, state, and zip
code must be listed
A7. Building diagram number
A8. a), b), and c) Enclosure and crawl space information for buildings that are diagrams 6, 7, or 8.
A9. a), b), and c) Attached garage information. If no attached garage, enter “N/A” in all three spaces.
SECTION B–FLOOD INSURANCE RATE MAP (FIRM) INFORMATION
B1. NFIP community name & community number
B4. Map and panel number
B5. Suffix
B7. FIRM panel effective/revised date
B8. Flood zone(s) in which the building is located
B9. Base flood elevation(s)

Elevation Certificates
SECTION C–BUILDING ELEVATION INFORMATION (when a survey is required)
C1. Building elevations based on: Note: “Finished construction” must be checked unless the
building is still under construction.
C2. All items are required to have an entry. If the datum is different from the datum used for the
BFE in Section B, the datum conversion must be recorded in this section or in Section D or
G, as appropriate.
Elevation items a), f), and g) must be recorded on every certificate. If an item does not
apply, enter “N/A” in the fields where no data are being supplied. If there are no flood
vents, items h) and i) should have “0” entered.
Items b) and c) must be completed with an elevation if they are applicable and if that letter
appears on the diagram on pages 6 and 7 of the instructions.
Where there is an attached garage, an elevation must be entered for item d), otherwise the
entry is “N/A.” Where there is machinery and/or equipment that service the building, an
elevation must be entered for item e), otherwise the entry is “N/A.”
SECTION D–SURVEYOR, ENGINEER, OR ARCHITECT CERTIFICATION
CERTIFIER’S NAME and LICENSE NUMBER
CERTIFIER’S SIGNATURE
DATE
The box at the end of Section D must have the certifier’s seal. [If there is a signature and/or date in the
box, there does not have to be a separate signature or date on the line.]
SECTION E–BUILDING ELEVATION INFORMATION (when a survey is not required in a Zone AO or
a Zone A without a base flood elevation)
E1. a) and b) Enter the difference between the top of the bottom floor and the highest and lowest
adjacent grade.
E2. For Building Diagrams 6–8 with openings (see page 8), enter the difference between the top of the
next higher floor and the highest adjacent grade.
E3. Enter the difference between the top of the garage slab and the highest adjacent grade.
E4 Enter the difference between the top of the platform for machinery or equipment and the highest
adjacent grade.
E5. Zone AO (only) Elevation of bottom floor complies with the ordinance (if there is no base flood
depth provided).
Note: If Section E is used, then Sections F or G must be completed.
SECTION F–PROPERTY OWNER (OR OWNER’S REPRESENTATIVE) CERTIFICATION
This section is used if Section E is completed by the owner or owner’s representative. If used, this section
must include the property owner’s or representative’s name in the first line and the signature in the third
line.
SECTION G–COMMUNITY INFORMATION
If G1 is checked, then the first and third lines after G9 (the local official’s name and signature) must be
completed. NOTE: If a local official, authorized by law to complete an elevation certificate, fills out ALL the
information (including elevation data), then G8, G9, and the signature block must be completed.
If any of these items is not completed or correct, the ISO/CRS Specialist will adjust the
element’s credit points. IF MORE THAN 20% OF THE SAMPLED ELEVATION CERTIFICATES HAVE
ONE OR MORE OF THESE DEFICIENCIES , THE COMMUNITY WILL LOSE ITS CREDIT FOR THAT

Elevation Certificates
It is the community’s responsibility to ensure that the elevation certificates it maintains
have been completed correctly. Certificates provided by surveyors must be proofread
and corrected if there are errors or omissions.
Although the surveyed elevations are likely to be correct, it is not unusual for surveyors to
enter the wrong FIRM date or diagram number or fail to complete all the entries in Section
C3. If there are certificates that have some of the above items omitted or incorrectly filled
out, the community has the following options:
1. For any inaccurate or incomplete information in Section C2, the local official
should request a new certificate. If Sections C2a)—c) are completed correctly, but
some information in Sections C2d)—g) is missing, the local official may visit the
site and collect the missing data by measuring from the surveyed floors.
2. The local official can do the following if incomplete or inaccurate information is
found in the other sections. The local official should not mark up the form with the
correct information.
a) The forms may be returned to the surveyor with instructions on what needs
to be changed or corrected;
b) The local official can prepare a separate memo with the correct information
and attach the memo to the form. When the certificate is provided to an
inquirer, the memo must be included with it; or
c) The local official can note the changes or corrections in Section G.
3. The corrections to Sections A, B, C1 can be made when the data on the certificate
is entered into a data base or elevation certificate software (see Section 311.d on
maintaining elevation certificates in computer format). It must be noted in Section
G what changes were made to the original paper copy. The local official should
check G1 when data are entered into a data base or elevation certificate software.
The community will still need to keep the original certificate, but can hand out
copies printed from the corrected digital version.
It should be noted that the community assumes responsibility for the accuracy of the changes
it makes. Therefore, data entry for digital versions should be double-checked.
Although surveyors may not be familiar with the intricacies of the form, they do know how to
survey elevations. One way communities have improved the quality of elevation certificates
is to complete Sections A and B at the time of permit application. The partially completed
form is given to the applicant or the surveyor who can then focus on completing the surveyed
information in Section C. This has been shown to reduce many of the more common errors.
CRS Coordinator’s Manual
310-6
Edition: July 2007
Elevation Certificates
In order to meet the requirements of the third prerequisite, the community must keep copies
of all credited elevation certificates readily available. The community must be able to retrieve
certificates for old permits, including those from projects whose permit files may have been
archived or discarded. The certificates may be maintained in a computer format, but the
community must be able to respond to inquirers who want to see the original hard copy. The
community may pass the cost of preparing the elevation certificate on to the permit applicant
and it may charge a reasonable fee to cover the cost of copying the certificates for inquirers.
a. Maintaining elevation certificates (EC) (Maximum credit: 56 points)
EC = 56 if the community maintains elevation certificates since the date of
application to the CRS. The community receives the full 56 credit points for EC
unless it is adjusted during the verification visit. If no permits have been issued for
structures within the SFHA since the community’s application date for the CRS,
EC = 56.
The community will automatically receive 56 points for EC because the CEO certifies in the
application that the forms will be maintained and made available. EC is only adjusted to less
than 56 points if the findings of the verification visit warrant such a reduction. As discussed
above, the credit points will be reduced if incorrect or incomplete information appears on the
elevation certificates checked during the verification visit.
b. Maintaining elevation certificates for post-FIRM buildings (ECPO) (Maximum credit:
56 points)
ECPO = 56 points if completed certificates are maintained for all buildings built or
substantially improved in the SFHA between the date of the community’s initial
FIRM and the date of application to the CRS. ECPO is adjusted according to the
ratio of post-FIRM buildings for which the community has certificates (see Section
312).
This credit is provided for having elevation certificates for all buildings built or substantially
improved in the SFHA since the date of the community’s initial FIRM. If the community only
has certificates for some of these buildings, then the value for ECPO is adjusted as described
in Section 312, Impact Adjustment.
c. Maintaining elevation certificates for pre-FIRM buildings (ECPR) (Maximum credit:
15 points)
CRS Coordinator’s Manual
310-7
Edition July 2007
Elevation Certificates
ECPR = 15 points if completed certificates are maintained for all buildings built or
substantially improved in the SFHA before the date of the community’s initial FIRM.
ECPR is adjusted according to the ratio of pre-FIRM buildings for which the community has certificates (see Section 312).
Although most communities did not keep elevation records before they joined the Regular
Program, lowest floor elevations may have been determined for a flood protection study. If
the data are transferred to the FEMA forms, credit can be provided under ECPR. If the
records cover only some of the pre-FIRM buildings, ECPR is adjusted in the same manner as
ECPO, as described in Section 312, Impact Adjustment.
NOTE: Elevation certificates can be completed by a local official who is authorized by law or
ordinance to administer the community’s floodplain management program, provided the
original surveyed data for Section C was obtained by a registered land surveyor, engineer, or
architect. A community can transfer data from a surveying project to the elevation certificate
form if it can demonstrate that the source of the data was appropriate.
For example, the National Flood Mitigation Data Collection Tool described in Section 511.b
can be used to collect a wealth of data on a building. If the local official can document that a
surveyor shot the elevations collected in the Tool, it would be relatively simple to transfer the
data to the elevation certificate form, which would be signed in Section G by the local
official.
d. Maintaining elevation certificates in computer format (ECCF) (Maximum credit: 15
points).
ECCF = 10 points if the elevation and floodproofing certificate data are kept in
computer format and provided to FEMA each year. An additional 5 points are
provided if the data for every property lists a street address. ECCF is adjusted
according to the ratio of all buildings that have elevation certificates that are also in
computer format (see Section 312). There is no credit if the data base does not
include all of the data needed for a FEMA elevation certificate.
This credit is available if the community has elevation records on a computer data base, and
is willing to provide FEMA with a disk or other computer-readable record. A program has
been developed to enter elevation certificate data on a personal computer. This program
meets the requirements for ECCF credit, and it is available free (see Appendix E). The
community must maintain and be able to retrieve the original signed hard copies.
Five additional points are provided if the community screens its data and makes sure that a
full street address is provided with each certificate. These five points are not available if
some properties are listed by lot and block number or other method.
CRS Coordinator’s Manual
310-8
Edition: July 2007
Elevation Certificates
e. Posting elevation certificate data on a website (ECWS) (Maximum credit: 20 points).
ECWS = 20, if the community has put elevation certificate data on a website that is
readily available to any inquirer (e.g., no payment of money is needed). There is no
credit if the data base does not include all of the data needed for a FEMA elevation
certificate.
Credit is provided if the community puts the elevation certificate data on a website that can be
accessed by the public. This can be in the form of a searchable data base, scanned elevation
certificates, or any other format that makes the data available. This credit is in addition to the ECCF
credit for providing FEMA with a disk that has elevation certificate data. In both cases, the data
base must include all of the data needed for a FEMA elevation certificate.
f. Off-site record storage (ORS) (maximum credit: 10 points):
ORS = 10, if all elevation certificates, regulations, plans, and other key records for
floodplain development permits are stored in a secure location, outside of any
floodprone area and at least one mile away from the permit office. The records must
be copied to the off-site storage location at least once each year.
In the past, hurricanes, fires, floods, and other disasters have destroyed local permit offices
and their files. This credit encourages communities to safeguard the records that document
how well a structure was protected from flood damage. Credit will be given if copies of such
documents (in digital, scanned, or paper format) are stored at a site out of the floodplain and
at least 1 mile away. The records must be transferred or copied to the off-site storage location
at least once each year.
A “secure location” means a site protected from fire, theft, and natural hazards (including a
category 5 hurricane). The site must not be subject to a flood hazard, i.e., a mapped Special
Flood Hazard Area, an X Zone location subject to local drainage problems, or a basement
with a known sewer backup problem. The community may submit a site that does not meet all
of these criteria (e.g., it is less than one mile away) if it can demonstrate that the site is secure
from fire, theft, flood, and other natural hazards (including a category 5 hurricane).

bECWS = the number of buildings with complete elevation certificate data
posted on the website.
ECPO and ECPR are adjusted to reflect the number of buildings with elevation certificates.
Section 301 includes a detailed discussion of the determination of bPO and bPR.
ECCF is adjusted if the community has not entered all elevation certificates into its computer
data base. ECWS is adjusted if the community has not entered all its elevation certificate data
onto the website.
There is no adjustment for EC because the community must maintain elevation certificates on
all buildings constructed in the SFHA after the date it applied for CRS classification.
However, the community may not have certificates on all post-FIRM or all pre-FIRM
buildings. Accordingly, ECPO and ECPR can be adjusted to reflect the number of buildings
that are affected. Similarly, ECCF and ECWS are adjusted if the community has not entered
all elevation certificates into its computer data base or website.
These adjustments are made by dividing the number of buildings with elevation certificates
by the number of buildings that could have certificates to produce an “r” variable that
represents the ratio of buildings affected. Sections 302 and 303 explain how to obtain the
building counts needed to calculate these impact adjustments.
NOTE: See the definitions of “building,” “SFHA,” and “Zone A” in the Glossary, Section
130. Also see Section 301.
Example 312.c-1. Floodville applied for CRS credit in late 1993. Its credit was
verified by its ISO/CRS Specialist during the spring of 1994. The examples for
Activity 310 show the CRS credit that was verified during that visit. Floodville applied
for 56 points for maintaining elevation certificates since its application date (EC); 14
points for having elevation certificates for at least 25% of its post-FIRM elevation
CRS Coordinator’s Manual
310-11
Edition: July 2007
Elevation Certificates
buildings (ECPO); and 4 points for having elevation certificates for at least 25% of its
pre-FIRM buildings. Although it started using the elevation certificate software after it
applied for the CRS, it did not have at least 25% of its certificates entered when it
applied. Its total application credit for Activity 310 was 74.
Floodville’s initial FIRM effective date is May 15, 1980. Between then and when it
applied to the CRS in 1993, 22 buildings were built or substantially improved: bPO =
22.
Floodville began using FEMA’s elevation certificates after FEMA conducted a
community assistance visit in 1986. It has completed certificates for all buildings built
since then. There are 10 such buildings: bECPO = 10.
rECPO = 10 = 0.45
22
There are 250 pre-FIRM buildings in Floodville: bPR = 250. As part of a flood control
study, the U.S. Army Corps of Engineers surveyed the first floor elevations of all
buildings in one of Floodville’s floodplains. Because there are no basements in
Floodville, the first floor is the same as the lowest floor. [NOTE: this is not always the
case; other sources of elevation data must be carefully checked to ensure that the
records are for the lowest floor.] The study provided elevations for 122 of Floodville’s
250 pre-FIRM buildings, and the city has subsequently recorded the data on FEMA’s
elevation certificates: bECPR = 122.
rECPR = 122 = 0.49
250
When it applied for the CRS, Floodville began using the CRS computer program for
maintaining elevation certificates. It also entered all of its post-FIRM and its preFIRM elevation and floodproofing certificates in this program. Because data from all
of the community’s certificates were in computer format by the time of the verification
visit, credit was verified using Option 1: rECCF = 1.0.
313 Credit Calculation
a. cEC = 56
b. cECPO = ECPO x rECPO
Example 313.b-1. Floodville has elevation certificates for 10 of its 22 post-FIRM
buildings. As discussed above: rECPO = 0.45.
cECPO = 56 x 0.45 = 25.2
CRS Coordinator’s Manual
310-12
Edition: July 2007
Elevation Certificates
c. cECPR = ECPR x rECPR
Example 313.c-1. Floodville has elevation certificates for 122 of its 250 preFIRM buildings. As discussed above: rECPR = 0.49.
cECPR = 15 x 0.49 = 7.35
d. cECCF = ECCF x rECCF
Example 313.d-1. Floodville entered all of its elevation and floodproofing
certificates in computer format. It also checked them all and made sure that each
one has a full street address. ECCF = 10 + 5 = 15. As discussed above: rECCF =
1.0
cECCF = 15 x 1.0 = 15.0
e. cECWS = ECWS x rECWS
f. cORS = ORS
g. c310 = cEC + cECPO + cECPR + cECCF + cECWS + ORS
Example 313.e-1. Floodville applies for participation in the CRS so it must apply
for this activity. The mayor certifies that the city will continue to use the FEMA
elevation certificates so the city receives the 56 points in the formula. As calculated
above, cECPO = 25.2, cECPR = 7.35, and cECCF = 15. The city has not put
elevation certificates on a website, so cECWS = 0. The city does not yet have off-site
storage for its records, so cORS = 0.
Floodville’s first activity worksheet is shown in Figure 310-1a.
C310 = 56 + 25.2 + 7.35 + 15 + 0 = 103.55, which is rounded to 104.
CRS Coordinator’s Manual
310-13
Edition: July 2007
Elevation Certificates
Ten buildings have been built or substantially improved in the floodplain since the
1993 CRS application. During the verification visit, the ISO/CRS Specialist examines
the elevation certificates for these buildings. A surveyor who completed one of the
certificates recorded the wrong FIRM Zone and the wrong base flood elevation. This
reduces Floodville’s credit for EC from 56 to 50.4.
Similar sampling for post-FIRM and pre-FIRM certificates found no other errors.
However, the sample taken for ECCF also found one error, which reduces that credit
from 15 to 13.5.
Floodville’s final verified credit for Activity 310 is:
c310 = 50.4 + 25.2 + 7.35 + 13.5 + 0 + 0 = 96.45, which is rounded to 96.
314 Credit Documentation
The community must have the following to verify implementation of this activity:
a. [If the community applies for credit under Section 311.b (ECPO) or c (ECPR) and it
used a form different from FEMA’s] A copy of its elevation certificate, along with
documentation that FEMA has approved it. Note that a local elevation certificate can
only be credited if it was used before the 1999 FEMA elevation certificate was
published or before the community joined the CRS, whichever is later.
If the community used a non-FEMA form in the past and began using the FEMA form when it
applied for the CRS or when the 1999 FEMA form went into effect, the written statement is
required to obtain credit for ECPO and/or ECPR.
b. [If the community applies for credit under Section 311.d.1 and is NOT using the CRS
“Computerized Format for FEMA Elevation Certificates”] A copy of the computer
format being used.
The CRS computer format is available at no cost (see Appendix E).
c. Copies of all completed elevation certificates that the community wants credited for
EC, ECPR, or ECPO. Sample copies of the digital or website versions will be
collected to document credit for ECCF and ECWS.
d. Documentation showing how the impact adjustment ratios were determined and a
description of how the community maintains, stores, and provides copies of
elevation certificates to inquirers. If the community is applying for credit for off-site
CRS Coordinator’s Manual
310-14
Edition: July 2007
Elevation Certificates
record storage (ORS) under Section 311.f, the documentation must describe the offsite storage location and arrangements for copying key files for that location..
The community must maintain certificates on all buildings built, substantially improved, or
placed in the floodplain since the initial application date and make them available. The
community should maintain its elevation certificates so they are easy to retrieve during the
verification visit.
The community must submit the following with its annual CRS recertification:
e. A disk with the elevation and floodproofing certificate data in computer format
obtained since the last submittal, if applying for credit for ECCF under Section
311.d. If the community is receiving credit for other than the FEMA-issued elevation
certificate software, the submittal must include a key that explains each data item.

Map Information Service
320 MAP INFORMATION SERVICE
Credit is provided for providing inquirers with information from the community’s Flood
Insurance Rate Map (FIRM), including whether a property is in a Special Flood Hazard
Area (SFHA), which zone, and its base flood elevation. Credit depends on publicizing
this service and advising inquirers about the mandatory flood insurance purchase
requirement.
Background: This public information service can greatly help a community’s residents
as well as its banks, insurance agents, real estate agents, and anyone else who needs
flood hazard information. It is particularly helpful to those who have trouble reading
maps, people from out of town, and those who do not have access to the latest maps.
This activity is also intended to bring other available community resources to bear on
each individual situation. Such resources include local topographic, planning, road, and
utility maps; geographic information systems; special hazard area maps; permit
records; and subdivision plats. Where they are available, these other resources can
complement the FIRM as sources of additional flood data or more detailed map
information. (NOTE: for compliance with the mandatory purchase requirement, the
current FIRM (or Letter of Map Change) is the only legal document allowed to be used
by lenders or third party vendors.)
Activity Description: There are seven prerequisites for full credit under this activity:
1. If requested, the community must provide all of the following FIRM information:
a. Whether the property is in an SFHA,
b. The community number,
c. The panel number and suffix,
d. The date of the FIRM’s index (cover panel),
e. The FIRM zone, e.g., A, C, X, V, AE, A2, AO, etc.,
f.
The base flood elevation (the depth in AO Zones) where shown on the FIRM,
g. The elevation datum used on the FIRM, if other than NGVD, and
h. Whether the property is on an undeveloped coastal barrier or “otherwise
protected area” as designated on the FIRM.
2. If the property is in an SFHA, the community must inform the inquirer of the
mandatory flood insurance purchase requirement, as appropriate. This may be done
by advising the inquirer that flood insurance may be required because of the
property’s location or by providing a written summary of the requirement (e.g., the
example in Figure 320-1).
CRS Coordinator’s Manual
320-2
Edition: July 2007
Map Information Service
3. If the community has a map that shows the coastal A Zone or Coastal Barrier
Resources System, the service must check on the following and report the findings
to the inquirer:
a. Whether the property is in a coastal A Zone. If so, the inquirer must be advised
that waves and velocity from coastal storms and hurricanes can cause
significant damage to a structure that is not properly elevated on an open
foundation and protected from erosion and scour.
b. Whether the property is in an “undeveloped coastal barrier” or “otherwise
protected area” of the Coastal Barrier Resources System. If so, the community
must advise the inquirer that flood insurance, federal disaster assistance, and
other types of federal financial assistance are not available for buildings
constructed or substantially improved after the effective date of designation, as
shown on the FIRM.
4. The map used for this service must be kept updated at least annually to reflect new
subdivisions, annexations, flood insurance restudies, map revisions, and map
amendments (including Letters of Map Amendment (LOMAs) and Letters of Map
Revision (LOMRs)). The community must also maintain copies of all FIRMs that
have been in effect since 1999 or the date the community applied for this credit,
whichever is later.
5. The service must be publicized at least once a year. If the community uses a
website for its services, the site’s address or URL must be publicized. The publicity
must state that the community also has copies of elevation certificates for some
properties in the floodplain.
6. If the community is receiving CRS credit for mapping and regulating one of the
special hazard areas described in Section 401, inquirers must be advised if the
property falls within a special hazard area and what precautions should be taken
when developing or improving the property.
7. The service must provide an opportunity for the inquirer to talk to community staff
about map and floodplain management questions.
There are many benefits to providing FIRM information. Residents and businesses that are
aware of the potential flood hazard can take steps to avoid problems and/or reduce their
exposure to flooding. Communities are the best source of map information because they can
often supplement and clarify the FIRM with complementary maps, and with information on
additional hazards, flooding outside mapped areas, development regulations that affect
floodplain properties, flood insurance, and property protection measures. NOTE: For
compliance with the mandatory purchase requirement, the current FIRM (or Letter of Map
Change) is the only legal document allowed to be used by lenders or third party vendors.
Acceptable methods of providing map information include, but are not limited to:
•
•
Reading the FIRM in response to a telephone call;
Helping a person who walks into the office read the FIRM;

Map Information Service
About the Mandatory Purchase of Flood Insurance Requirement
NFIP: This community participates in the National Flood Insurance Program (NFIP), which makes
federally backed flood insurance available for all eligible buildings, whether they are in a floodplain or not.
Flood insurance covers direct losses caused by surface flooding, including a river flowing over its banks, a
lake or ocean storm, and local drainage problems.
The NFIP insures buildings, including mobile homes, with two types of coverage: building and contents.
Building coverage is for the walls, floors, insulation, furnace, and other items permanently attached to the
structure. Contents coverage may be purchased separately, if the contents are in an insurable building.
Mandatory Purchase Requirement: The Flood Disaster Protection Act of 1973 and the National Flood
Insurance Reform Act of 1994 made the purchase of flood insurance mandatory for federally backed
mortgages on buildings located in Special Flood Hazard Areas (SFHAs). It also affects all forms of Federal
or Federally related financial assistance for buildings located in SFHAs. The SFHA is the base (100-year)
floodplain mapped on a Flood Insurance Rate Map (FIRM). It is shown as one or more zones that begin
with the letter “A” or “V.”
The rule applies to secured mortgage loans from such financial institutions as commercial lenders, savings
and loan associations, savings banks, and credit unions that are regulated, supervised, or insured by Federal
agencies such as the Federal Deposit Insurance Corporation and the Office of Thrift Supervision. It also
applies to all mortgage loans purchased by Fannie Mae or Freddie Mac in the secondary mortgage market.
Federal financial assistance programs affected by the laws include loans and grants from agencies such as
the Department of Veterans Affairs, Farmers Home Administration, Federal Housing Administration, Small
Business Administration, and the Department of Homeland Security’s Federal Emergency Management
Agency (FEMA).
How it Works: Lenders are required to complete a Standard Flood Hazard Determination (SFHD) form
whenever they make, increase, extend or renew a mortgage, home equity, home improvement, commercial,
or farm credit loan to determine if the building or manufactured (mobile) home is in an SFHA. It is the
Federal agency’s or the lender’s responsibility to check the current Flood Insurance Rate Map (FIRM) to
determine if the building is in an SFHA. Copies of the FIRM are available for review in most local
government building or planning departments. Lenders may also have copies or they use a flood zone
determination company to provide the SFHD form.,
If the building is in a SFHA, the Federal agency or lender is required by law to require the recipient to
purchase a flood insurance policy on the building. Federal regulations require building coverage equal to
the amount of the loan (excluding appraised value of the land) or the maximum amount of insurance
available from the NFIP, whichever is less. The maximum amount available for a single-family residence is
$250,000. Government sponsored enterprises, such as Freddie Mac and Fannie Mae, have stricter
requirements.
The mandatory purchase requirement does not affect loans or financial assistance for items that are not covered by a
flood insurance policy, such as vehicles, business expenses, landscaping, and vacant lots. It does not affect loans for
buildings that are not in an SFHA, even though a portion of the lot may be. While not mandated by law, a lender may
require a flood insurance policy, as a condition of a loan, for a property in any zone on a FIRM.
If a person feels that a SFHD form incorrectly places the property in the SFHA, he or she may request a Letter of
Determination Review from FEMA. This must be submitted within 45 days of the determination. More information
can be found at http://www.fema.gov/fhm/fq_gen11.shtm.

•
Completing a form based on a marked-up street map sent in by an inquirer (see
example, Figure 320-2). It is recommended that a local form or form letter include
a disclaimer like the one in Figure 320-2; or
Directing an inquirer to a website or other provider of the service, provided that
the inquirer can obtain the information by entering a street address. There is no
credit for simply having a map on the website or expecting an inquirer to read the
map.
The community may charge a reasonable fee for providing map information to cover staff
time and office overhead. This service should not include surveying or similar costs to collect
new data, such as ground elevations.
To receive credit for this activity, the community’s program must meet all seven of the
prerequisites. The following comments correspond to these prerequisites.
1. The list in Section 1 of the Activity Description comprises the FIRM information needed
to complete most of Section B of the FEMA elevation certificate (see Section 310). A
copy of the elevation certificate for the property, if available, can suffice as meeting the
minimum requirements. There is no pro-rating for providing only some of the needed map
information.
The community need only supply the flood data requested. If the inquirer only wants to
know if a building is in a floodplain, then advising whether it is in an SFHA as shown on
the FIRM is sufficient. If a property is too close to the SFHA boundary to determine what
FIRM zone the building is in, the community may give the inquirer a copy of the FIRM
and advise that the FIRM zone cannot be determined based on the map information
available.
The community is not required to provide data that do not appear on the FIRM, such as
base flood elevations in unnumbered A Zones, but providing additional information from
other maps and sources of flood hazard and flood protection information is encouraged.
The community must respond to an information request within a reasonable period of
time.
2. If the person performing the map information service finds that a property is in the SFHA,
he or she must inform the inquirer about the mandatory flood insurance purchase
requirement (see Figure 320-1).
•
An alternative is to provide a summary similar to that in the booklet, “Mandatory
Purchase of Flood Insurance Guidelines,” FEMA-186, listed in Section 324, For
More Information. A third alternative is to hand out a one-page summary, as
shown in Figure 320-1. Handouts may be easier for the community to produce and
distribute, but they do not necessarily help people who have trouble reading
technical material or who want simple answers to simple questions.

is located in a Special Flood Hazard Area (SFHA). The base flood elevation
at the property is:
, NGVD. Federal law requires that a flood zone
determination be done as a condition of a federally backed mortgage to
determine if the structure is in an SFHA and if so, to require flood
insurance. It is up to the lender to determine whether flood insurance is
required for a property.
is not located in a Special Flood Hazard Area. However, the property may
still be subject to local drainage problems or other unmapped flood hazard.
Flood insurance from the NFIP is available at non-floodplain rates. A flood
insurance policy can still be required by a lender.
A decision about the building’s exact location cannot be made on the FIRM.
A copy of the FIRM is attached for your information.
Flood insurance from the NFIP is available for any property in Floodville.
More information on flood insurance is attached. This office has copies of
FEMA Elevation Certificates for all buildings constructed in the SFHA since
1990. Questions on this letter and the City’s floodplain management program
are welcome at this office by calling 555-123-1234.
NOTE: This information is based on the Flood Insurance Rate Map for the City.
This letter does not imply that the referenced property will or will not be
free from flooding or damage. A property not in a Special Flood Hazard Area
may be damaged by a flood greater than that predicted on the FIRM or from a
local drainage problem not shown on the map.

Map Information Service
Communities should be aware that federally regulated lenders are legally responsible for
determining if a flood insurance policy is required for a loan. Under the National Flood
Insurance Reform Act of 1994, if a “third party vendor,” i.e., someone other than a lender,
provides map information to decide if a flood insurance policy is required for a loan, the
information must be guaranteed. Communities are not considered third party vendors.
This activity credits providing map information to inquirers. It is not intended to
encourage communities to assume the lender’s responsibility. See also Figure 320-3.
Flood Hazard Determination Review
Activity 320 credits a map information service provided by the community. The mandatory purchase
requirement places the responsibility on lenders to determine whether to require a flood insurance policy
as a condition of a loan (see Figure 320-1). Many lenders hire map determination companies as third party
vendors to assist them.
Sometimes a property is incorrectly placed in the SFHA by the lender or its map determination company.
The property owner may come to the community asking for help or advice. The local official is welcome
to double check the determination, but the inquirer should be informed that the determination is the
lender’s responsibility and the local government has no authority over it.
If it appears that the property is outside the SFHA, but the map determination says that it is inside, the
owner can ask FEMA for a determination review within 45 days of the notice. A Flood Hazard
Determination Review is requested jointly by the owner and the lender. Procedures for requesting the
review can be found at http://www.fema.gov/fhm/fq_gen11.shtm.
If the submittal is complete and on time, FEMA will issue a Letter of Determination Review (LODR).
This review does not result in an amendment or revision to the effective FIRM. It is only a finding about
the location of a building or manufactured home relative to a designated SFHA.
A LODR only affects the Federal requirement for purchase of flood insurance. However, the mortgage
lender always has the option to require flood insurance as a condition of providing financing, regardless of
the location of the structure. If the map needs to be changed, the property owner can submit a request for a
Letter of Map Amendment (LOMA).
Figure 320-3. Flood hazard determination review.
3. Coastal A Zones are those parts of a community’s coastal floodplain, inland from the
mapped V Zone (or shoreline if there is no mapped V Zone), that are subject to the
damaging effects, of waves, velocity flows, erosion, scour, or combinations of these
forces. The community must provide map information on coastal A Zones if they have
been mapped. This may be when FEMA provides an advisory flood elevation map or
FIRM that shows areas subject to waves over 1.5 feet or if the community is receiving
credit for regulating coastal A Zones under Section 431.p (CAZ). For more information on
mapping coastal A Zones, see Section 431.p.
CRS Coordinator’s Manual
320-7
Edition: July 2007
Map Information Service
Unless the community has coastal A Zone regulations, such as those credited under
Section 431.p, the information is provided solely to inform inquirers of the additional
flood hazard in the area. If the inquirers are considering building or remodeling, the
information should encourage them to incorporate appropriate flood protection design
measures. More information on design measures can be found in the Coastal Construction
Manual (FEMA 55) and Recommended Residential Construction for the Gulf Coast:
Building on Strong and Safe Foundations (FEMA 550) and related references that can be
found on the Information Resource Library on FEMA’s website .
“Undeveloped coastal barriers” and “otherwise protected areas” of the Coastal Barrier
Resources System are designated as such by Congress. The intent is to prohibit most
expenditures of federal funds within these coastal barriers. The CBRA provisions are
summarized in Figure 320-4.
If the local official cannot determine whether a property is within a designated coastal
barrier or otherwise protected area, he or she can inform the inquirer to check with the
U.S. Fish and Wildlife Service, either at a local office or by checking the website at
http://www.fws.gov/habitatconservation/coastal_barrier.htm .
If the person providing the map information service finds that a property is in a
designated coastal barrier, he or she must inform the inquirer about the designation, the
fact that a flood insurance policy cannot be sold for a building constructed after the date
of designation, and the limits on federal assistance.
Communities with designated undeveloped coastal barriers should determine the date(s)
on which the restrictions went into effect locally. More information on the rules for these
areas can be found in the Flood Insurance Manual for insurance agents, by checking with
the U.S. Fish and Wildlife Service or its website, http://www.fws.gov/habitatconservation/
coastal_barrier.htm .
4. The community, as well as a lender, must use the latest FIRM. The community is
responsible for ensuring that the FIRM it uses is updated to reflect new subdivisions and
changes in corporate limits. The community’s FIRM also needs to show all new FIRM
data from flood insurance restudies, map revisions, and map amendments. This may mean
plotting every Letter of Map Amendment (LOMA) and Letter of Map Revision (LOMR)
or noting on the paper FIRM that LOMAs and LOMRs have been issued.
The community must also maintain copies of prior FIRMs that have been in effect since
1999 or the date the community applied for this credit, whichever is later. It is
recommended that the community maintain a copy of every FIRM that has been published
(credit for this is available under Activity 440 (Flood Data Maintenance)). Copies of prior
FIRMs may be available from the National Service Provider’s Regional Management
Centers (see Section 324.e).
Communities that use a digital map, GIS, or map overlays should consider applying for
credit for Activity 440 (Flood Data Maintenance), which has the same prerequisite.
CRS Coordinator’s Manual

Map Information Service
The Coastal Barrier Resources System
The Coastal Barrier Resources Act of 1982 (CBRA), and the Coastal Barrier Improvement Act of
1990 removed the federal government from financial involvement associated with building and
development in undeveloped portions of coastal areas (including the Great Lakes). These areas were
mapped and designated as Coastal Barrier Resources System (CBRS) units and Otherwise Protected
Areas. They are colloquially called “CBRA areas.” (pronounced “cobra” but not spelled that way).
Any federal program that may have the effect of encouraging development on coastal barrier islands is
restricted by law. These programs include “any form of loan, grant, guarantee, insurance, payment,
rebate, subsidy or any other form of direct or indirect Federal assistance” with specific and limited
exceptions. For example, federal disaster assistance is limited to emergency relief in CBRA areas—
there are no loans or grants to repair or rebuild buildings in those areas.
The legislation also banned the sale of National Flood Insurance Program (NFIP) flood insurance for
structures built or substantially improved on or after a specified date. For the first CBRA designations,
that date is October 1, 1983. For all subsequent designations, it is the date the CBRA area was
identified. CBRA areas and their identification dates are shown in the legend of Flood Insurance Rate
Maps (FIRMs).
If an owner of a building in a CBRA area wants to buy flood insurance, he or she would need a copy
of the building permit showing that the building was properly built before the designation date and a
signed statement from the floodplain ordinance administrator that it had not been substantially
damaged or improved since then. The insurance agent may need to provide more documentation.
The boundaries of a CBRA area cannot be revised through the Letter of Map Amendment or Revision
(LOMA/LOMR) process. They can only be revised through:
● Congressional action,
● Interpretation of boundaries by the U.S. Department of the Interior’s Fish and Wildlife Service,
or
● Cartographic modifications by Department of Homeland Security’s FEMA to correct errors in
the transcription of the Department of the Interior maps onto FIRMs.
If an NFIP policy is issued in error in a CBRA area, it will be cancelled and the premium refunded. No
claim can be paid, even if the mistake is not found until a claim is made.
If a grandfathered building (i.e., a building built before the date of designation) is substantially
improved or substantially damaged, its flood insurance policy will be cancelled.
Lenders are required to notify borrowers if the structure is in a CBRA area and that NFIP flood
insurance and/or disaster assistance may not be available . Many lenders are reluctant to lend without
protecting their investment with flood insurance and private flood insurance may not be available.

CRS Coordinator’s Manual
320-9
Edition: July 2007
Map Information Service
5. The map information service must be publicized at least once a year. The publicity must
say that elevation certificates are available for public review. For example, if the
community started keeping elevation certificates after 1990, the publicity could state
“Copies of FEMA elevation certificates on all buildings constructed in the floodplain
since 1990 are available at the Building Department.”
Publicity for the service may be directed to the entire community or to three key
audiences: lenders (banks, savings and loans, credit unions, etc.), insurance agents, and
real estate agents. This can be done in one of three ways:
a) Advise everyone about the map information service through one of three kinds of
outreach projects:
•
An outreach project to the community credited under OPC in Activity 330
(Outreach Projects);
•
An outreach project pursuant to the public information strategy (OPS) credited in
Activity 330, provided the public information strategy document discusses the best
way to advise the target audiences; or
•
An outreach project that advises all residents and businesses in the community
about the service, but is not credited under Activity 330 (e.g., a short notice with
all tax or utility bills).
b) An annual mailing (or e-mail) to all local lenders and insurance and real estate
agencies. If the community cannot reach all three of these target audiences, it may
receive partial credit for this activity.
c) An annual article in the newsletters or magazines of appropriate organizations, such as
the local Board of Realtors®, the local chapter of the American Bankers Association,
or the state’s insurance department. If the Chamber of Commerce or similar
organization has a newsletter that reaches all the appropriate offices in the community,
a notice in the newsletter will suffice.
These publicity methods are described in more detail in Section 323, Credit
Documentation. The first method would be the most efficient and economical one if the
community can use an existing newsletter or other annual mailing that reaches everyone
in the community. The third approach can help where there are many communities
implementing this activity and where one bank or insurance agency deals with several
communities (in metropolitan areas, for example). A master list of communities providing
map information could be prepared and distributed each year by a state or regional
agency.
6. The CRS credits mapping and regulating special flood-related hazards, such as subsidence
and coastal erosion. These credits are described in Section 401, Special Hazard Areas, and
in separate publications. If the community is receiving CRS credit for mapping and
regulating one of these hazards, the map information service must include telling inquirers
CRS Coordinator’s Manual
320-10
Edition: July 2007
Map Information Service
if the property in question is also in the mapped special hazard area and any additional
regulatory requirements the community may have for developing properties in that area.
7. The service must provide an opportunity for the inquirers to talk to community staff about
map and floodplain management questions. One value of the map information service is
that it provides an opportunity for the staff person responding to the inquiry to determine
whether all of the inquirer’s questions have been answered and to provide additional
information on related topics, such as permit requirements and past flooding.
Therefore, the service must include an opportunity for personal contact. If the service is
provided remotely, such as through a website, contractor, or by taking written or faxed
requests, the annual publicity and the response to the inquirer must include a telephone
number that can be called for further questions about map information and the
community’s floodplain management program.
A community may enter into an agreement with another agency, such as a regional
planning commission, to provide map information. To receive CRS credit, there must be a
written agreement that clarifies that the agency providing the service will respond to all
inquirers and will allow the ISO/CRS Specialist to verify its work. The service must be
publicized and a record of the inquiries must be maintained to facilitate verification of
this credit (see Sections 323.b, c, and d).
321 Credit Points
Maximum credit for Activity 320: 140 points
Map Information Service:
MI = 140 points, if the community’s service meets all seven of the prerequisites
described under the Activity Description.
Credit is dependent upon both providing and publicizing the service. The community’s
method of providing map information and the accuracy of the information will be checked
during the verification visit. The score for MI will be adjusted accordingly.
Example 321-1. Floodville responds to verbal and written inquiries. If the
property cannot be located easily based on the street address, the lot and block
numbers are requested. The form shown in Figure 320-2 is completed and signed by
the building official. A copy of the form is kept in a separate file.
When the city designed the map information form, it met with local insurance agents
and obtained an order form for flood insurance brochures and “stuffers.” They are
available free in quantity from the National Flood Insurance Program. Floodville also
prepared a flyer based on the information in Figure 320-1. If a property is located in
CRS Coordinator’s Manual
320-11
Edition: July 2007
Map Information Service
an SFHA, the appropriate box is checked and a stuffer and the flyer are attached to
the form.
The publicity for Floodville’s service is explained in Example 323.a-1. Because the
service is provided and publicized, MI = 140.
322 Credit Calculation
c320 = MI
Example 322-1. As explained above, MI for Floodville = 140.
During the verification visit, the ISO/CRS Specialist confirms that the maps are being
read correctly in all five of the samples checked.
c320 = 140 x 1.0 = 140.
323 Credit Documentation
The community must submit the following documentation:
a. Documentation that shows how the community publicizes the service each year.
The publicity must:
•
be distributed at least once a year;
•
explain how to access the service, i.e., what telephone number to call, or what
internet address to use to access the website;
•
provide a telephone number for more information about flood maps and the
community’s floodplain management program (if different from the number to
call for the map information service); and
•
describe what elevation certificates are available for public review.
1. If the community publicizes this service through an annual outreach project
credited under Activity 330 (OPC or OPS), the publicity materials may be
included with the documentation for Activity 330. “320” must be noted in the
margin of the outreach project where the map information service is addressed.
If an OPS is used, the public information strategy document must discuss the
best way to publicize the map information service to the target audiences.
CRS Coordinator’s Manual
320-12
Edition: July 2007
Map Information Service
2. If the community publicizes this service through an annual outreach project that
is not credited under Activity 330, a copy of the project. The materials must be
distributed each year and must reach at least 90% of the properties in the
community (vacant lots are not counted).
3. If the community sends a letter or e-mail directly to lending institutions and real
estate and insurance agencies, a copy of the letter or e-mail message.
4. If the community notifies organizations of lending institutions and real estate and
insurance agencies, copies of the notices in their publications. If any of the
organizations has not yet published the notices, documentation must include
written assurance from the organization that it intends to publish the notification
within six months of the CRS application date.
Example 323.a-1. Floodville’s State NFIP Coordinator has initiated a system of
sending a master list of communities that provide map information to the state offices
that regulate lenders and insurance agents. The list is also sent to the state Board of
Realtors®. The Coordinator met with these offices and gave them sample articles
that are used to publicize the local services. Copies of the articles actually published
and sent to lenders, insurance agents and real estate agents are included with
Floodville’s application. The article for the insurance agents’ publication includes a
note that Floodville also has FEMA elevation certificates available for all buildings
constructed in the floodplain since 1986.
Example 323.a-2. Watertown sends a brochure to all addresses in the
community as an OPC outreach project in Activity 330. Included is the following
notice:
Floodplain Questions?
If you want to know if a property is in the Special Flood Hazard Area, check
our website at www.Watertown.org/flood/mapinfo. You’ll find a wealth of
information on the City’s Flood Insurance Rate Map, flood insurance, special
rules for building in the floodplain, and ideas for protecting your property
from flood damage. Or you can call the Building Department with all of your
floodplain questions at 555/123-4567. The Building Department also has
copies of FEMA elevation certificates for all buildings constructed in the
floodplain since 1987.
CRS Coordinator’s Manual
320-13
Edition: July 2007
Map Information Service
b. If another agency or organization provides map information, documentation that the
agency agrees to provide the service to all inquirers and will allow the CRS to verify
its work.
The community must have the following documentation available to verify
implementation of this activity:
c. Records of which institutions and agencies were notified of this service. If the
community sends letters to institutions and agencies, a mailing list for those
institutions and agencies.
d. A record or log noting:
1.
the date of the inquiry,
2.
the address or location of the property in question,
3.
the FIRM zone,
4.
whether the inquirer was advised of the rules on mandatory flood insurance
purchase,
5.
for properties in coastal floodplains, whether the inquirer was advised of
6.
(a)
the coastal A Zone hazard, and
(b)
the CBRA areas and the financial assistance and flood insurance
limitations in those areas (if appropriate); and
Whether the inquirer was advised of additional special flood-related hazards
and the precautions that should be taken when developing or improving the
property (where appropriate).
Copies of letters will suffice for this documentation where the information is provided in
writing. A sample of such a letter is shown in Figure 320-2. A log is required if information is
given orally or on the telephone. A sample log is shown in Figure 320-5. Copies of the log or
letters are also required if another agency or organization provides the map information.
e. Documentation showing how the community keeps the FIRM updated at least
annually to reflect new subdivisions, annexations, flood insurance restudies, map
revisions, and map amendments (including LOMAs and LOMRs). The community
must also have copies of all FIRMs that have been in effect since 1999 or the date
the community applied for this credit, whichever is later.

NOTE: If all of the map information comes from the same FIRM, the community
number is not logged. The community in this example has only one FIRM based
upon NGVD, so the FIRM date and datum are not included in the log. Also, the
panel number logged includes the suffix. The community has all of the data
required for this activity in its log.
Communities that have no coastal A Zones or undeveloped coastal barriers
designated on their FIRMs or special flood-related hazards do not need the
last column of the log.
Communities receiving credit for one or more of the special flood-related
hazards need to include a column on special hazards as a reminder to advise
inquirers if the property is subject to that hazard.

System Maintenance), and 610 (Flood Warning Program). Outreach projects should be
designed with these publicity needs in mind. An example of this is shown in Figure 330-1.
331 Credit Points
Maximum credit for Activity 330: 380 points
Credit for the outreach projects is based on both the type of project and the topics
covered. For credit, an outreach publication must fully cover a topic. There are 10
topics that can be covered to receive full credit under OPC, OPF, or OPA.
1. The local flood hazard.
2. Flood safety (required for full credit under Activity 610, Flood Warning Program).
3. Flood insurance (required for repetitive loss area outreach projects under
Section 503).
4. Property protection measures (required for repetitive loss area outreach projects
under Section 503).
5. The natural and beneficial functions of the local floodplain.
6. A map of the local flood hazard.
7. The flood warning system (required for full credit under Activity 610, Flood
Warning Program).
8. Floodplain development permit requirements.
9. The substantial improvement/substantial damage requirements.
10. Drainage system maintenance (required for full credit for stream dumping
regulations under Activity 540, Drainage System Maintenance).
Examples of a variety of outreach projects, including samples of several brochures produced
by federal agencies and others, are included in the publication CRS Credit for Outreach
Projects. This publication is available at no cost (see Appendix E).
Credit usually will not be given if an outreach project contains only a single sentence on a
topic. As discussed below, the topic should be covered in enough detail to be useful to the
reader. If the information provided in one year is inadequate for Community Rating System
(CRS) credit, the community may augment it and apply for additional credit in a modification
in a later year (see Section 215).
CRS Coordinator’s Manual
330-3
Edition: July 2007
Outreach Projects
The 10 topics that can earn credit are
1. The local flood hazard: The project should include the source(s) of flooding (such as
the names of the rivers or a statement that the greatest threat is storm surge from the
ocean), information about past floods, and additional data on local flooding, such as
velocities or the possibility of mudflows. At a minimum, this should include all flood
hazards discussed in the community’s Flood Insurance Rate Map (FIRM) and Flood
Insurance Study and the approximate location of the boundary of the community’s
coastal A Zone, where known (e.g., “most properties seaward of Ocean Boulevard are
in the coastal A Zone, where the flood hazard is greater due to waves and velocities”).
If the community provides map or additional flood hazard information as credited
under Activities 320 (Map Information Service) or 360 (Flood Protection Assistance),
the service could be publicized under this topic.
2. Flood safety: Emergency precautions should be discussed, such as turning off the
electricity and gas, not wading through moving floodwaters, or staying clear of
unstable stream banks. Precautions against driving through flooded areas must be
included. If the community is applying for credit for emergency warning
dissemination under Activity 610 (Flood Warning Program), it must receive full credit
for covering this topic. In coastal areas, the project should explain the need to
evacuate when an evacuation order or advisory is issued.
3. Flood insurance: The project should note that standard property insurance does not
cover flood damage but that flood insurance is available in the community. It should
include some basic facts, such as why flood insurance is important, the 26% chance of
experiencing a flood during the life of a 30-year mortgage, the types of insurance
coverage, and the fact that there is a 30-day waiting period before coverage goes into
effect. The project should note whether the community has any undeveloped coastal
barriers where insurance may not be available. This topic must be covered in the
outreach project that is implemented to meet the annual notice requirement for
repetitive loss communities (see Section 503.e).
4. Property protection measures: Measures to protect a property from flood damage
include retrofitting, grading a yard, correcting local drainage problems, and such
emergency measures as moving furniture and sandbagging. Retrofitting measures are
discussed in Activity 530 (Flood Protection). In areas subject to hurricanes and
tropical storms, measures that protect against high winds should be mentioned, such as
installing storm shutters and reinforced garage doors.
If the community provides property protection or retrofitting advice as credited under
Activity 360 (Flood Protection Assistance), the service could be publicized under this
topic. This topic must be covered in the outreach project that is implemented to meet
the annual notice requirement for repetitive loss communities (see Section 503.e).
5.
Natural and beneficial functions: The outreach project should discuss the natural
and beneficial functions of local floodplains, any unique local features, the importance
of protecting these functions, and how they can be protected. For CRS credit the
discussion must address local conditions.
CRS Coordinator’s Manual
330-4
Edition: July 2007
Outreach Projects
6. Map of the local flood hazard: If the project includes a map of the community’s
flood hazard areas, it must meet the following criteria:
a. The map must clearly show every street affected, although all streets do not have
to be named. Major streets must be named. If parcel lines or other linear features
are shown, they must be readily distinguishable from streets.
b. The floodprone area must be clearly shown through shading or another method. In
coastal communities, the coastal areas affected by storm surge from different
categories of hurricanes can be shown on the map as an alternative to showing the
floodplain. If the community is receiving CRS credit for mapping or managing the
coastal A Zone or areas subject to special flood-related hazards, then such areas
must be included on the map to receive full credit for this topic.
c. The map must be at a scale of at least 1 inch = 1 mile (about 1:62,500). A map to a
smaller scale, such as 1 inch = 2 miles (1:125,000) may be appropriate for large
rural areas with few streets.
7. The flood warning system: Information on warning procedures, signals used,
warning time, what radio and/or television station(s) to tune to, and similar data
should be disseminated. These items must be covered if the community is applying for
credit for emergency warning dissemination under Activity 610 (Flood Warning
Program) (see Section 611.b.1(e)). No credit is awarded if the community does not
have a flood warning system.
8. Floodplain development permit requirements: The outreach project should explain
that all developments in the floodplain (not just construction of buildings) need local
permits. People should be advised to contact the community’s regulatory department
before they build, fill, or otherwise develop. They should also be told how to report
illegal floodplain development.
9. The substantial improvement/damage requirements: The National Flood Insurance
Program (NFIP) requires that if the cost of reconstruction, rehabilitation, addition, or
other improvements to a building equals or exceeds 50% of the building’s market
value, then the building must meet the same construction requirements as a new
building. Substantially damaged buildings must be brought up to the same standards
(e.g., a residence damaged so that the cost of repairs equals or exceeds 50% of the
building’s value before it was damaged must be elevated above the base flood
elevation).
The outreach project should summarize the requirements (which are in the
community’s floodplain management regulations) and the local procedures for
enforcing them. More information on the substantial improvement and substantial
damage rules can be found in Answers to Questions about Substantially Damaged
Buildings, FEMA-213 (see Section 334.e).
10. Drainage system maintenance: The project should discuss regulations against
dumping in channels, how to report violations, and why it is important to maintain the
drainage system. These items must be covered if the community wants full credit for

Outreach Projects
its stream dumping regulations under Activity 540 (Drainage System Maintenance),
(see Section 541.b.2 and the example shown in Figure 330-1).
The Department of Homeland Security’s Federal Emergency Management Agency (FEMA)
has funded several research projects to find out what will motivate people to protect
themselves from flooding. These projects have concluded that a properly run public information program can motivate property owners to protect themselves from flood damage.
One experiment showed that a direct mailing to floodplain residents was as effective as more
expensive combinations of mailings, public meetings, and radio and television advertising.
The research found that an effective public information program should be based on these
principles:
1. An initial outreach document should not be long and detailed. The objective is to raise
the property owner’s interest by explaining the general idea of flood protection. More
detailed information can be made available in a library or through technical assistance
(see Activities 350 (Flood Protection Information) and 360 (Flood Protection
Assistance)).
2. The message must be clear and unambiguous. It should be consistent throughout the
material used. It should be written to be understood by the lay person.
3. The information should be geographically personalized so that readers see that it
specifically addresses their situation. A brochure with a picture of a flooded local
landmark will have a stronger impact than a state or federal publication. Individually
addressed notices are more effective than general articles, maps, or letters addressed
to “Occupant,” because they clearly tell recipients that they are affected.
4. The recipient must view the information source as credible, authoritative, and
relevant. A statement by the city engineer may be more appropriate than one by the
governor.
5. The information should cover the risk of flooding without being too technical.
Property owners must be convinced that they will be flooded someday.
6. The message must clearly articulate the most desirable measures. These measures
must be appropriate for the hazard, affordable, and perceived as “realistic” by a
property owner. They should fit in with the appearance of the area’s housing.
7. The information should discuss the costs and benefits of various protection measures.
It should include the up-to-date dollar costs of implementing each measure.
8. Because no retrofitting measure is foolproof, especially against higher, less frequent
floods, flood insurance should always be recommended. In areas subject to basement
flooding, the community should investigate the availability of private insurance
coverage for sewer backup and sump pump failure.
CRS Coordinator’s Manual
330-6
Edition: July 2007
7. Requiring signs posted in subdivisions to advise visitors of the flood hazard.
8. Requiring deeds to show the lot or building elevation in relation to sea level and
the base or historical flood elevation.
9. Requiring a seller to disclose if the property is subject to a flood-related special
hazard.
A community may apply for credit under one of these additional approaches, even if it does
not have a real estate agent notification program. These approaches do not have to be local
requirements. In many cases, these disclosure methods are required by state law.
This list is not meant to be all-inclusive. The objective of the ODR credit is to provide
information to people before they are committed to owning or occupying a property with a
flood hazard. Because these approaches do not affect as many people while they are actually
looking for a property (as agent disclosure does), fewer credit points are provided.
Furthermore, because they are difficult to verify in the field, these approaches must be based
on a law or other explicit legal mandate.
Example 341.b-1. Floodville is seeking credit for two other disclosure
requirements. One is based on a state law that requires that before they are
recorded, all subdivision plats are to “include an engineer’s or surveyor’s statement
as to which lots, if any, are partially or completely located in an area of special flood
hazard identified pursuant to the National Flood Insurance Act of 1968.” [5 points]
Floodville’s zoning and building codes require that property records show all special
requirements that have been imposed as a condition of building in a floodplain: “A
record of each variance, special use permit, and conditional use permit, and all
conditions and stipulations attached thereto, shall be provided to the County
Recorder of Deeds to be filed with the record of the property.” [5 points]
The city’s application includes a photocopy of these two quoted legal requirements:
ODR = 10.
Requirements for identifying the floodplain or flood elevations on preliminary plats or permit
applications are not disclosure requirements and are not credited. ODR credit is based on a
legal requirement to disclose the flood hazard on a record or notice that will be seen by
potential purchasers or occupants of a property.

Hazard Disclosure
c. Real estate agents’ brochure (REB) (Maximum credit: 10 points)
REB = 10, if real estate agents are providing brochures or handouts that advise
potential buyers to investigate the flood hazard for a property. This credit is
available even if the community does not receive credit for Disclosure of the Flood
Hazard under Section 341.a.
An example of such a brochure is shown in Figure 340-1. A locally tailored brochure
describing the community’s flood hazard would be very useful. Sellers, in particular, may
appreciate as complete a description as possible, especially if the flooding is shallow and
slow-moving and retrofitting or other protective measures are appropriate and inexpensive.
Purchasers of vacant land should be well aware of factors such as the depth, velocity, and
warning time of the base flood.
Example 341.c-1. Floodville has given each real estate office several hundred
copies of the brochure shown in Figure 340-1. The real estate agents give one to
every client, including those looking at properties outside the floodplain: REB = 10.
d. Disclosure of other hazards (DOH) (Maximum credit: 10 points)
DOH = 10, if the notification to prospective buyers credited in Section 341.a
includes disclosure of other flood-related hazards, such as the coastal A Zone,
erosion, subsidence, or wetlands. This credit is available only if the community also
receives credit for DFH.
Disclosure programs should not be limited to flood hazards. Potential property purchasers
should be advised of other hazards that have been identified for specific sites. Coastal A
Zones, erosion, subsidence, and wetlands are the site-specific hazards mentioned above.
Others include dam failure, volcanoes, landslides, and wildfire, as well as tsunamis and the
other special hazards listed in Section 401. Disclosing one hazard should trigger interest in
others, so a broader-based program will be more effective.
CRS Coordinator’s Manual
340-6
Edition: July 2007
The most common approach is to have a box in the MLS form. In this case, a photocopy of a
completed MLS form must be submitted as documentation, along with a statement that all or
most of the local agencies use the MLS form.
b. [Required only if the community is applying for ODR credit] A copy of ordinance or
law language requiring one or more additional disclosure methods at the time of
sale or rental of a property. The acronym “ODR” must be marked in the margin of
the sections that pertain to this element.
This documentation need only be submitted if the community is requesting credit for one of
the other disclosure requirements discussed in Section 341.b. A photocopy of the appropriate
pages of the ordinance or statute is sufficient and should be attached to the activity
worksheet. The Chief Executive Officer’s (CEO’s) application certification is considered to
include a certification that the ordinance or statute has been enacted into law and is being
enforced.
c. [Required only if the community is applying for REB credit] A brochure or other
document that is made available to interested parties by real estate agents. The
document must advise people looking to purchase property to investigate the flood
hazard before they buy.
See Figure 340-1 for ideas on what should be included in a brochure.
d. [Required only if the community is applying for DOH credit] Documentation that the
notification in Section 341.a includes disclosure of other flood-related hazards, such
as the coastal A Zone, erosion, subsidence, or wetlands.
Maps that disclose information about other flood-related hazards to prospective purchasers
are encouraged. In some states, coastal erosion or recession maps have been prepared. Coastal
communities receiving credit under Activity 320 (Map Information) should disclose whether
a property is in the coastal A Zone or is part of the Coastal Barrier Resources System. Some
communities have mapped areas subject to land subsidence and are regulating new
construction in those areas. Others have mapped and zoned wetlands or other sensitive areas.
This activity gives credit for including these hazards on the same form or notice that is
credited under DFH.

400 MAPPING AND REGULATIONS
The Community Rating System (CRS) provides credit to communities that enact and enforce
regulations that exceed the National Flood Insurance Program’s (NFIP’s) minimum standards
so that more flood protection is provided for new development.
The activities in this series affect only certain portions of the community and, in some cases,
only portions of the floodplain. Therefore, the credit points are adjusted to reflect the area
affected. These activities are also adjusted to reflect the community’s growth rate. Section
710 explains this credit.

400-2
Edition: July 2007
If a site-specific or local study is conducted for an area shown on the FIRM as a numbered A
or V Zone or AE or VE Zone, then the only way to receive Community Rating System (CRS)
credit for a new study is if the base flood elevation is raised. If it is lowered, the map revision
will mean a reduction in the size of the SFHA and lower flood elevations. The map revision
will reduce flood insurance premiums more than a CRS classification. The CRS does not
provide additional or duplicate credit.
There may be cases where a new profile is higher than the old base flood elevations in some
areas and lower in other areas. In such cases, the reaches that qualify for credit must be
identified on the impact adjustment map and scored accordingly. The reaches with new base
flood elevations that are lower than the old elevations are not credited under NS.
If a new detailed study resulted in a floodplain larger than the previously mapped SFHA, then
the community should mark the new floodplain as “AFD1” and “AFD2.” AFD1 would be
coterminous with the FIRM’s SFHA. AFD2 would be the area outside the SFHA where base
flood elevations are used to regulate development in B, C, D, or X Zones. The points for NS2
will be higher than for NS1.
b. Leverage (LEV) (Range: from 0 to 1.0)
1. If the community has data on the study costs:
LEV = Non-FEMA share of the study cost
Total cost of the study
2. If the community does not have financial data on the study costs, then
LEV = the total of the following:
(a) 0.25, if a better topographic map was contributed to the study effort,
(b) 0.15, if other contributions were made to the study effort.
3. If the community adopts advisory flood elevations (AFEs) or flood recovery data
provided by FEMA, the value of LEV is based on how quickly the AFEs or such
data are adopted.
(a) Full credit is provided if the AFEs are adopted within 30 days. No credit is
provided if they are adopted more than six months after they are published.
LEV = (180 – DAYS) ,
150
where DAYS =
CRS Coordinator’s Manual
The maximum value for LEV is 1.0
the number of days between the date the AFEs are
published by FEMA and the date they are adopted by the
community. The value of DAYS ranges from 1 to 180 (six
months).
410-13
Edition: July 2007
Additional Flood Data
(b) If a community enacts a moratorium on new construction, and repairs of
substantially damaged buildings from the time of the disaster to adoption of
AFEs, then LEV = 1.0.
(c) If a community adopts a regulatory elevation higher than the base flood
elevations shown on its current FIRM, but lower than the published AFEs,
the value for LEV will be pro-rated.
(d) This credit for LEV stays in effect until the second cycle verification visit after
publication of a revised FIRM with base flood elevations equal to or higher
than the AFEs.
LEV is a ratio with a range of 0 to 1.0. If the study was financed entirely by non-FEMA
resources, LEV = 1.0. Non-FEMA resources include the community, the state, a regional
agency, the property owner, a developer, the Corps of Engineers, the Natural Resources
Conservation Service, and any other agency or organization other than FEMA or a FEMAfunded program.
If the study was fully funded by FEMA, then LEV = 0. Communities do not receive NS or
LEV credit for Flood Insurance Studies and FIRMs that are fully funded by FEMA.
If the community is a Cooperating Technical Partner, there should be readily available figures
on how much the study cost and the amounts paid by FEMA, the community, and other
involved agencies. If the Cooperating Technical Partner agreement is for the community to
contribute 20% of the cost of a new study, then LEV = 0.2.
If the community, state, or other agency made an in-kind contribution, such as staff time or
base maps, it can be converted to a dollar value on the Cooperating Technical Partner
Mapping Activity Statement using FEMA “Blue Book” values. If the effort cannot be
converted to dollars, then LEV = 0.25 or 0.15, according to the formula. If the dollar value
results in a ratio lower than 0.25 or 0.15, then the higher figure can be used.
Flood Insurance Studies or restudies cost shared with a state agency, the U.S. Army Corps of
Engineers, the Tennessee Valley Authority, the Natural Resources Conservation Service, or
other federal agency are credited PROVIDED that the agency was not paid by FEMA for the
work. Many studies are conducted by a state or federal agency under contract to FEMA or
under the Limited Map Maintenance Program. In these instances, no LEV or NS credit is
given.
Generally, if the additional flood data can be found in the original Flood Insurance Study,
then FEMA paid the full cost, and LEV = 0. In some areas, the community, state, or regional
district helped fund the study or paid for better topographic base mapping that was then
included in the Flood Insurance Study. In these cases, the community must document its
contribution. Often, the community’s contribution is mentioned in the Flood Insurance Study
text and a copy of the appropriate page is sufficient.
CRS Coordinator’s Manual
410-14
Edition: July 2007
Additional Flood Data
Example 411.c-1. Floodville paid all of the costs for its study of the problem
ditch in the C Zone, AFD1. LEV1 = 1.0. Developers pay for calculating base flood
elevations in the A Zone along Deadman’s Creek, AFD2. LEV2 = 1.0.
Example 411.c-2. Watertown’s Engineering Department analyses are funded by
the City. LEV1 = 1.0.
Watertown signed a Cooperating Technical Partner agreement with FEMA to restudy
the Riley River. The agreement has the City funding $50,000 toward the study and
contributing its GIS contour map. These contributions are calculated to equal
$150,000. The total cost of the study is $250,000.
LEV2 = $150,000 = 0.6
$250,000
Watertown’s efforts equate to 60% of the cost of the Riley River restudy. In Section
413, the values for NS for this study are multiplied by 0.6, resulting in 60% of the
credit for those elements. Note that Watertown will not receive this credit for the
restudy until it is completed and adopted in the City’s floodplain management
regulations.
The third option for LEV credit can be used when FEMA provides advisory flood elevations
after a major storm. In many areas, the storm surge from a hurricane exceeds the base flood
elevations on the current effective FIRM. When this happens, it raises questions about the
validity of the current FIRM’s base flood elevations. FEMA conducts a reassessment of those
elevations to see if they reflect the true risk. Flood Recovery Guidance is developed to
provide communities with advisory flood elevations (AFEs) that they can use in the
reconstruction process until more detailed data become available.
Normally a FEMA-funded flood study will not receive any credit under the CRS (i.e., LEV
= 0). However, adopting higher flood elevations immediately after a storm can have a major
positive impact on reconstruction and redevelopment in the floodplain. Therefore, a special
exception is made to encourage communities to adopt their AFEs as quickly as possible.
Delaying adoption of AFEs decreases their value over time as more properties are reconstructed to the pre-storm base flood elevations. Accordingly, the formula for LEV reduces the
credit if the community delays adoption. The value for LEV can range from 1.0 when the
AFEs are adopted within one month of their publication by FEMA (DAYS = 30) to 0.4 if they
are adopted four months later (DAYS = 120) to zero if they are adopted six or more months
later (DAYS = 180).
CRS Coordinator’s Manual
410-15
Edition: July 2007
Additional Flood Data
It should be noted that if FEMA subsequently provides a new FIRM using the AFEs, adoption
of the higher elevations is no longer optional. Adopting the elevations will be a minimum
requirement of the NFIP and the community will lose this credit (i.e., LEV = 0) at the second
cycle verification visit after publication of the new FIRM. This means a Class 6–9 community
will keep the credit for a minimum of five years after the new FIRM makes adoption of the
higher elevations mandatory.
It is hoped that before this happens, the community will have acquired, relocated, elevated, or
otherwise protected many of its damaged buildings and will receive enough credit under
Activities 520 (Acquisition and Relocation) or 530 (Flood Protection) to offset this possible
loss of credit.
Should a subsequent FIRM have base flood elevations that are lower than the AFEs and the
community opts to keep the AFEs in its regulations, then it will not lose this credit.
Example 411.c-3. Gulf Isle was hit by Hurricane Katrina in August 2005. FEMA
published AFEs on November 15, 2005. The AFEs are higher than the BFEs in the
current FIRM and extend the floodplain boundaries into the current FIRM’s X Zones.
The AFEs receive 150 points NS credit for higher BFEs and V-Zone boundaries in
original AE and VE Zones and 240 points NS credit for providing BFEs in the FIRM’s
X Zones. With the impact adjustment, Gulf Isle would receive 270 points for NS if the
new study had been fully funded by a non-FEMA source.
If the Gulf Isle City Council adopted the AFEs by December 14, 2005, DAYS = 30:
LEV = (180 – DAYS) = (180 – 30) = 150 = 1.0
150
150
150
LEV = 1.0 and c410 = 270 x 1.0 = 270.
If the Council waited until February 20, 2006, DAYS = 97
LEV = (180 – DAYS) = (180 – 97) = 83 = 0.65
150
150
150
LEV = 0.65 and c410 = 270 x 0.65 = 175.5.
If the City Council did not adopt the AFEs until after May 15, 2006, DAYS > 180 and
LEV = 0. There would be no CRS credit for adopting the AFEs.

c. Higher study standard (HSS) (Maximum credit: 160 points)
HSS credit is provided for the following higher study standards:
•
•
•
•
Using future conditions hydrology,
Using a higher confidence limit when calculating the 100-year discharge,
Using better topographic data, and
Showing 500-year flood elevations and the boundaries of the 500-year
floodplain.
Additional higher study standards may be submitted by the community. FEMA
will determine if they warrant credit for HSS.
The credit points are cumulative for each study, not to exceed the maximum
listed.

The points for HSS are cumulative. For example, a new profile (line 3) in an X Zone that
used future conditions hydrology and better topographic data would receive 80 + 80 = 160
points for HSS. If the study also used a higher confidence limit when calculating the 100-year
discharge, the total for HSS (80 + 80 + 80) would exceed the maximum allowed per study and
the score would be capped at 160. This is added to the NS score in Section 413, Credit
Calculation.
A community may receive credit for HSS in areas where it does not receive credit for NS. For
example, credit can be provided if the FIRM (or a later map adopted for regulatory purposes)
was based on future conditions hydrology, provided the community’s floodplain development
regulations use base flood elevations based on future conditions.
Some background on the listed higher standards.
•
Using future conditions hydrology: Future-conditions hydrology means that flood
discharges associated with projected land use conditions are based on a community's
zoning maps and/or comprehensive land use plans and without consideration of
projected future construction of flood detention structures or projected future
hydraulic modifications within a stream or other waterway, such as bridge and culvert
construction, fill, and excavation. When the hydrologic study is based on future land
use conditions, discharges will be higher than those from a study based on current
development conditions.
CRS Coordinator’s Manual
410-17
Edition: July 2007
Additional Flood Data
If a long-range plan is used, its target date must still be at least five years away. For
example a study done in 1985 based on land use in the year 2010 will not receive
credit after 2005. However, if the hydrology was based on a fully developed
watershed, there is no expiration of the credit.
•
Using a higher confidence limit when calculating the 100-year discharge: Hydrology
studies produce “estimates” of peak flows. The estimates used are the “best”
estimates, which means that they are high 50% of the time and low 50% of the time.
Using a higher confidence interval means that the estimates are too high more often
and too low less often. For example, a 90% confidence limit means that the quantity of
flow used to map a floodplain will be too high 90% of the time and too low 10% of the
time. The result is a more dependable estimate of the 100-year flow.
•
Using better topographic data: This credit is for using a base map that has
topographic data better than what is available from the U.S. Geological Survey.
Either:
•
The map has contour intervals smaller than what is available from the U.S.
Geological Survey’s digital orthophoto quarter quads (DOQQs), or
•
In those areas where there are no DOQQs, the credit is provided if the contour
interval is smaller than that on the area’s USGS quadrangle maps.
Example 411.b-1. Because Floodville expects that a large proportion of its
drainage areas will be urbanized, its problem ditch study (AFD1) used a base flood
discharge based on full watershed development (future conditions hydrology). AFD1
credit is based on line 3 and the original FIRM Zone was “C.” (HSS1 = 80 points).
The City’s floodplain management ordinance requires developers on Deadman’s
Run (AFD2) to use future conditions hydrology. AFD2 credit is based on line 2 and
the original FIRM Zone was “A.” (HSS2 = 40 points).
Example 411.b-2. Watertown’s site-specific analyses do not include any higher
study standards. HSS1 = 0.
d. More restrictive floodway standard (FWS) (Maximum credit: 200 points)
FWS credit is based on the allowable floodway surcharge used to prepare the
floodway map. The community or the state must document that a state or local law
sets a maximum allowable surcharge.
1. FWS = 200, if the floodway delineation was based on no allowable rise in the
flood elevation,
CRS Coordinator’s Manual
410-18
Edition: July 2007
Additional Flood Data
2. FWS = 150, if the allowable rise was from 0.01 to 0.2 feet,
3. FWS = 100, if the allowable rise was from 0.21 to 0.5 feet, or
4. FWS = 50,
if the allowable rise was from 0.51 to 0.99 feet.
Figure 410-5 shows the standard approach to mapping a floodway. If the floodway was based
on the FEMA surcharge standard of 1.0 foot, then there is no credit for this element. If a
floodway map is based on some other standard (such as a limitation on velocity or a change in
velocity) to determine more restrictive floodways, the community must determine the actual
reduction in floodway surcharge that results. Since floodway analysis is almost always
performed by the step-backwater method, the data provided for each cross section should be
used to determine the actual average floodway surcharge.
Many times a floodway study prepared according to the minimum NFIP guidelines produces a
floodway surcharge of less than 1 foot at some cross sections. The fact that the average
floodway surcharge is less than 1 foot does not qualify the community for FWS credit. The
floodway surcharge must be reduced by a mapping standard that can be documented by the
community.
Example 411.c-1. Floodville’s state law requires that all floodway delineations
be based on a 0.5-foot allowable floodway surcharge. In areas with floodways
delineated according to this standard, FWS = 100.
This standard was used in the study for the problem ditch (AFD1): FWS1 = 100.
There is no floodway study required for the site-specific analyses on Deadman’s Run
(AFD2): FWS2 = 0.
On Foster Creek the City uses the floodway provided with the Flood Insurance
Study. That floodway was based on the state’s 0.5-foot surcharge standard. Because
state law required that it be prepared to a higher standard than that specified in
Guidelines and Specifications for Flood Hazard Mapping Partners, the Foster Creek
floodway can be credited. The area affected is the A15 Zone, which is designated as
AFD3. Therefore, FWS3 = 100.
NOTE: Credit for FWS should not be confused with the minimum NFIP requirement that new
development in the floodway may not result in any increase in flood heights. The FWS credit
is for using a more restrictive standard to delineate the floodway.

Example 411.c-2.
(See Figure 410-4.) When Watertown’s Engineering
Department conducts site-specific analyses to calculate base flood elevations for
permit applicants in certain areas outside the SFHA (AFD1), it also conducts an
encroachment study to see if the applicant’s project will increase flood heights . A
0.1-foot surcharge is required by state law. This standard is used for these studies:
FWS1 = 150.
Watertown designates the floodplain on the Riley River as AFD2. Watertown’s Flood
Insurance Study on the Riley River used the state standard: FWS2 = 150.
e. Additional flood data for special hazards (AFDSH): (Maximum credit: 50 points)
Credit for mapping areas of special flood-related hazards is described in separate
CRS publications on special hazards.
If a community is applying for credit for mapping and regulating any of the special floodrelated hazards, described in Section 401, it should turn now to the appropriate publications
that are listed in Section 415.b. The credit points for mapping these areas are calculated
separately. The resulting credit points, AFDSH, are then transferred to this activity.
f. Cooperating Technical Partner (CTP) (Maximum credit: 141 points)
(1) CTP1 = the total of the following
10, if the community is a Cooperating Technical Partner. The community must
have signed a Cooperating Technical Partner agreement with FEMA that
identifies shared mapping responsibilities and costs.
10, if the community is in a regional agency OR state that has signed a
Cooperating Technical Partner agreement with FEMA. The agreement must
identify the community or one of its flood problem areas as being studied.
This credit is provided only for Cooperating Technical Partner agreements
that relate to new studies or study standards. No credit is provided for
agreements that only provide information on existing studies and data.
Cooperating Technical Partners are communities, regional agencies, or states that have the
interest and capability to be active partners in FEMA’s flood mapping program. Regional
agencies that would qualify are those that are active in floodplain mapping, such as regional
drainage or sanitary districts. They may also include county agencies active in preparing
maps for both unincorporated and municipal floodplains. However, there is no credit for the
community if the agreement does not affect a floodplain map in that community.
CRS Coordinator’s Manual
410-21
Edition: July 2007
Additional Flood Data
Cooperating Technical Partners enter into an agreement that formalizes their contribution and
commitment to flood mapping. The objective of the program is to maximize limited funding
by combining resources and to help maintain consistent national standards.
Each Cooperating Technical Partner enters into an agreement with FEMA, specifying what
mapping activities it will implement. These could be as varied as:
•
Refinement of approximate Zone A boundaries,
•
Hydrologic and hydraulic modeling and floodplain mapping,
•
DFIRM preparation and maintenance,
•
Redelineation of detailed flood hazard information using updated topographic
data,
•
Digital base map data sharing,
•
Hydrologic and hydraulic review of requests for map revision, or
•
Adoption of specific technical standards or processes appropriate for local
conditions.
(2) CTP2 =
1.1, if the study or standard was prepared pursuant to the Cooperating
Technical Partner program. This provides a 1.1 multiplier that increases
the additional flood data credit by 10%.
1.0, if the study or standard was not prepared pursuant to the Cooperating
Technical Partner program or if it was prepared before the community,
regional agency, or state signed the Cooperating Technical Partner
agreement. The multiplier of 1.0 means that the credit points are not
changed.
CTP1 provides credit for participating in the Cooperating Technical Partners program. When
the program produces new studies or revises mapping standards, the community should
receive credit under the other elements of Activity 410.
CTP2 increases the credit received under Activity 410 by 10% to recognize the extra benefits
of the Cooperating Technical Partner program. CTP2 is a multiplier of the total score for each
study or standard (AFD). If the study or standard was not done pursuant to a Cooperating
Technical Partner agreement, then the score is multiplied by 1.0 and does not change.
CRS Coordinator’s Manual
410-22
Edition: July 2007
Additional Flood Data
Example 411.f-1.
Watertown signed a Cooperating Technical Partner
agreement with FEMA to restudy the Riley River. The state NFIP coordinating
agency also signed a Cooperating Technical Partner agreement to review flood
studies and provide other mapping support services.
CTP1 = 10 + 10 = 20
Watertown can receive CTP1 credit now. After the restudy for the Riley River is
completed and adopted in the City’s floodplain management regulations, CTP2 will =
1.1. Watertown’s score for the restudy will then receive a 10% credit bonus.
412 Impact Adjustment
a. Option 1:
rAFD: If the standards in the area of AFD apply throughout the SFHA as shown on
the community’s FIRM, rAFD = 1.0.
Under Option 1, only one set of standards may be credited for AFD.
This option for rAFD can be used only if ALL of the area in the community’s SFHA is under
the standards of AFD. This would be the case, for example, if all of a community’s SFHA is a
numbered A Zone with a higher floodway standard. However, if part of the community’s
SFHA is unnumbered A Zone or coastal, this option cannot be used. If the community
regulates areas outside its SFHA, it may get more credit by using Option 3.
Example 412.a-1. Singletown is affected by only one source of flooding: Single
Creek. The Flood Insurance Study for Single Creek used the state’s standard of a
0.1-foot floodway surcharge. Because the Single Creek floodplain covers the entire
SFHA, Singletown uses Option 1: rAFD = 1.0.
b. Option 2:
rAFD: If a single set of standards for AFD does not apply throughout the SFHA, the
community may use an impact adjustment of rAFD = 0.25. If there is more than one
set of standards for AFD, the community should choose the area with the highest
value for AFD when using Option 2.
A community may opt to use the default value of 0.25 for rAFD if it does not want to take the
time to prepare an Impact Adjustment Map or if it estimates that it would receive more points
by using the minimum value of Option 2.
CRS Coordinator’s Manual
410-23
Edition: July 2007
Additional Flood Data
c. Option 3:
rAFDi: The size of the area to which the standards of AFDi apply (aAFDi) must be
determined in order to adjust the credit points to reflect its impact. This impact is the
ratio of aAFD to the area of SFHA (aSFHA).
rAFDi = aAFDi
aSFHA
The maximum value for ∑rAFDi = 1.5.
All areas must be mutually exclusive.
Because all of a floodplain benefits from a more restrictive floodway surcharge,
aFWS includes the entire width of that reach of the floodplain, not just the area of
the floodway.
The Impact Adjustment Map is explained in Section 403. If there is more than one area, each
done to a different standard, each area is marked separately, i.e., AFD1, AFD2, etc. If several
areas were mapped or studied to identical standards, they are marked with the same acronym
and number (see Figures 410-3 and 410-4).
The area of the SFHA (aSFHA) is the same for all instances of AFD. It is calculated based on
the SFHA of the FIRM being revised by the newly adopted data. However, if a map revision
reduces the size of the SFHA, the area calculations may be based on the new area (which will
be to the community’s benefit, because it increases the value of rAFD).
ΣrAFDi stands for the sum of all of the impact adjustment ratios for AFD (i.e., rAFD1 +
rAFD2 + rAFD3 + . . .). The sum of all rAFDi cannot be greater than 1.5. In this activity, an
impact adjustment ratio greater than 1.0 reflects the fact that the community is regulating
floodplain development in areas not identified on the FIRM. It is presumed that this will
provide significant savings in future flood damage and NFIP claims, so the impact adjustment
ratio for this activity may go up to 1.5.
NOTE: All areas marked AFDi must be mutually exclusive. If the community does not
regulate outside of the SFHA, then ΣrAFDi cannot be greater than 1.0.
Example 412.c-1. In Floodville, the floodplain for the unnamed ditch is marked
as AFD1 on the city’s Impact Adjustment Map shown in Figure 410-3. The
Deadman’s Run A Zone is marked AFD2, and the Foster Creek floodplain is marked
AFD3. Floodville’s CRS Coordinator uses the grid square overlay method to determine the areas affected. He estimates these areas in acres:
aAFD1 = 71
CRS Coordinator’s Manual
aAFD2 = 58
aAFD3 = 267
410-24
Edition: July 2007
Additional Flood Data
aSFHA = 58 + 267 = 325
rAFD1 = aAFD1 = 71 = 0.22
aSFHA 325
rAFD2 = aAFD2 = 58 = 0.18
aSFHA 325
rAFD3 = aAFD3 = 267 = 0.82
aSFHA 325
ΣrAFDi = 0.22 + 0.18 + 0.82 = 1.22, so ΣrAFDi ≤ 1.5.
Note that on Figure 410-3, AFD1 overlaps with AFD3. Because all areas must be
mutually exclusive, Floodville can only count the overlapped area once. It should
count the overlapped area under the AFD with the higher flood elevation, the
elevation that takes precedence in the floodplain management regulations.
Therefore, the overlapped area is counted under AFD3.
Example 412.c-2. (See Figure 410-4.) Watertown’s Impact Adjustment Map
shows the areas outside the SFHA where site-specific analyses are required as
AFD1. The Riley River floodplain is designated as AFD2.
Watertown’s engineer used a planimeter to measure the area of the SFHA (which is
also the area of AFD2).
aSFHA = 0.55 square miles. When the area covered by the federal prison is
removed from consideration, aSFHA = 0.43 square miles. aAFD2 = aSFHA = 0.43.
The city’s regulations requiring site-specific analyses (AFD1) cover 12,000 feet of
stream channel. The area of AFD1 is the length times the width. Since the area
regulated is 100 feet on each side of the channel, the width is 100 x 2 = 200.
aAFD1 = 12,000 x 200 = 2,400,000 square feet or 0.09 square miles (see Section
404 for the conversion of square feet to square miles).
Using Option 3, rAFD1 = aAFD1 = 0.09 = 0.21
aSFHA 0.43
rAFD2 = aAFD2 = 0.43 = 1.0
aSFHA 0.43
ΣrAFDi = 0.21 + 1.0 = 1.21, so ΣrAFDi < 1.5.

413 Credit Calculation
a. AFDi = ((NSi x LEVi) + HSSi + FWSi) x rAFDi x CTP2i
b. c410 = ΣAFDi + (AFDSHi x CTP2i) + CTP1
Example 413.b-1. In Floodville (see Figure 410-3):
1. AFD1 = detailed study of the problem ditch in the C Zone.
NS1 = 290 HSS1 = 80 LEV1 = 1.0 FWS1 = 100 rAFD1 = 0.22
Floodville does not receive any CTP credit, CTP1 = 0, CTP2 = 1.0.
AFD1 = ((290 x 1.0) + 80 + 100) x 0.22 x 1.0 = 470 x 0.22 x 1.0 = 103.4
2. AFD2 = the site-specific analyses required for Deadman’s Run.
NS2 = 75 HSS2 = 40 LEV2 = 1.0 FWS2 = 0
rAFD2 = 0.18 CTP2 = 1.0
AFD2 = ((75 x 1.0) + 40 + 0) x 0.18 x 1.0 = 115 x 0.18 x 1.0 = 20.7
3. AFD3 = the more restrictive floodway prepared for Foster Creek. This higher
floodway standard was included in the City’s original Flood Insurance Study, so
there is no NS, HSS, or LEV credit.
NS3 = 0 HSS3 = 0 LEV3 = 0 FWS3 = 100 rAFD3 = 0.82 CTP2 = 1.0
AFD3 = ((0 x 0) + 0 + 100) x 0.82 x 1.0 = 100 x 0.82 x 1.0 = 82.0
4. Floodville does not receive any CTP credit, CTP1 = 0,
c410 = AFD1 + AFD2 + AFD3 + CTP1 = 103.4 + 20.7 + 82.0 + 0 = 206.1
Example 413.b-2. Watertown has two areas with additional flood data as shown
on its Impact Adjustment Map in Figure 410-4.
1. AFD1 = the site-specific analyses conducted by the city’s Engineering
Department on all streams with a drainage area larger than 40 acres.
NS1 = 100 HSS1 = 0 LEV1 = 1.0 FWS1 = 150 rAFD1 = 0.21 CTP2 = 1.0
AFD1 = ((100 X 1.0) + 0 + 150) x 0.21 x 1.0 = 250 x 0.21 x 1.0 = 52.5
2. AFD2 = the Riley River floodplain covered by the original Flood Insurance Study.
The City receives no NS, HSS, LEV or CTP2 credit at this time. However, it will
when the restudy is completed and adopted in the City’s floodplain management
regulations. Watertown receives credit for the state’s higher floodway standard
(FWS).
NS2 = 0 HSS2 = 0 LEV2 = 1.0 FWS2 = 150 rAFD2 = 1.0
CTP2 = 1.0
AFD2 = ((0 x 0) + 0 + 150) x 1.0 x 1.0 = 150 x 1.0 x 1.0 = 150

3. Because the City and the state have signed Cooperating Technical Partner
agreements, CTP1 = 10 + 10 = 20, even though the Riley River restudy has not
been completed.
c410 = ΣAFDi = AFD1 + AFD2 + CTP1 = 52.5 + 150 + 20 = 222.5
414 Credit Documentation
The community must submit the following:
a. The ordinance or law language that adopts the flood study for regulatory purposes
or that requires site-specific flood elevation or floodway studies to be conducted at
the time of permit application.
The ordinance or law should either specify what standard is to be used or adopt the studies or
maps for regulatory purposes.
Example 414.a-1. Appropriate regulatory language could read:
The floodplain delineation map for Skunk Creek, dated January 15, 1998, is
adopted and included in the area of jurisdiction of this ordinance. OR
The flood protection elevation shall be the base flood elevation shown on the
flood profiles in the Flood Insurance Study for the County. In floodplains where
the Flood Insurance Study does not provide a profile, the applicant shall
calculate the base flood elevation and submit it to the County Engineer for
approval and use as the flood protection elevation. OR
The areas of mudflow hazard subject to the management requirements of this
ordinance shall be as shown on the Geologic Hazard Maps produced by the
State Geological Survey.
NOTE: This Coordinator’s Manual contains examples of certifications and ordinance
language. Communities are advised to have all certifications and proposed ordinances
reviewed by their attorneys or corporation counsels.
b. Either:
(1) A copy of the study or an explanation of the technique used and a licensed
professional engineer’s statement that the study was based on a technique
approved by FEMA; OR
CRS Coordinator’s Manual
410-27
Edition: July 2007
Additional Flood Data
(2) A copy of the Flood Insurance Study pages or Letter of Map Revision (LOMR)
that show that the study has been accepted by FEMA to revise the FIRM.
Only those pages of the study that explain the elements for which the community is applying
need to be submitted. For example, if the community is applying for credit for a higher
floodway standard, the page from the Flood Insurance Study explaining the standard used and
an excerpt from the Floodway Data Table would suffice.
Under b.(1), the documentation must also include a statement signed by a licensed
professional engineer that the technique used in the study or the ordinance language has been
accepted by FEMA. It is not necessary to have the FEMA Regional Office specifically
approve the study, if the technique is listed as an acceptable one in Guidelines and
Specifications for Flood Hazard Mapping Partners.
Example 414.b-1. Engineer’s language for a study could read:
The attached study for Unnamed Ditch #1 was prepared using hydrological and
hydraulic engineering methods that have been approved by FEMA. The
hydrology was prepared using HEC-1 and the flood profiles were prepared
using HEC-2, techniques that are listed in FEMA’s Numerical Models Meeting
the Minimum Requirement of the NFIP. The study was submitted on November
12, 2004, with a request for a Letter of Map Revision. The LOMR was issued on
January 14, 2005.
Example 414.b-2. Engineer’s language for an ordinance requirement could
read:
Section 123.4 of Ordinance No. 89-23 requires all applicants for a development
permit in unnumbered A Zones to calculate a base flood elevation and delineate
a floodway for their development sites. The ordinance states that the applicant
may use any method listed as acceptable in the current edition of FEMA’s
Guidelines and Specifications for Flood Hazard Mapping Partners.
c. [If the community requested credit for the independent review under Section 411.a]
Documentation that the state or other agency reviewed and accepted the study or
analysis techniques for which credit is being requested.
Documentation will usually be a letter from the responsible agency, stating that the review
was done and/or that the data were approved.
CRS Coordinator’s Manual
410-28
Edition: July 2007
Additional Flood Data
The community must have the following documentation available to verify
implementation of this activity:
d. [Required only if the community is applying for credit under Section 411.b] For Flood
Insurance Studies that were partly paid by FEMA, documentation that describes the
non-FEMA share and who paid for it.
This documentation may be included in the engineer’s statement described in Section 414.b.
Note that many flood insurance studies and restudies were conducted by federal agencies and
private consulting firms under contract to FEMA. This activity credits only the share of a
study that FEMA did not finance.
Many communities are eligible for this credit if they shared in the cost of preparing the
original Flood Insurance Study or subsequent revisions. The non-FEMA contribution may be
in the form of direct financial participation or in-kind services, such as hydrologic studies or
topographic mapping. The community must be able to document the non-FEMA participation.
e. [If the community determines the impact adjustment ratios using Option 3 (412.c)]
The Impact Adjustment Map with the appropriate acronyms marking the areas
affected by the additional flood data. Each area with the same standard(s) should
be marked “AFD.” If more than one standard was used, the areas should be marked
“AFD1,” “AFD2,” etc. Different areas mapped to the same standards should all be
marked with the same acronym.
The Impact Adjustment Map is discussed in Section 403. If the community has additional
flood data that affect more than 25% of its floodplain, then it will receive more points if it
uses Option 3 as discussed in Section 412.c.
f. [If the community is requesting credit for CTP2, Cooperating Technical Partner,
under Section 411.f] Documentation that shows the relation between the study or
standard and the Cooperating Technical Partner agreement.
The community must have the following documentation available at its cycle
verification visit:
g. [If the community has received credit for a new study (NS) under Section 411.a] A
statement by the community’s engineer that its regulatory floodplain maps and
related data reflect current conditions. This statement need only address the maps
that are credited by this activity.
CRS Coordinator’s Manual
410-29
Edition: July 2007
Additional Flood Data
The community’s engineer must sign a statement that addresses the following issues:
(1) Whether the precipitation data used for the study’s hydrology are still appropriate
and have not been replaced by new data, such as a new publication of standard
precipitation data.
(2) Whether the basis for the hydrology still reasonably reflects the current watershed
conditions.
(3) Whether the method used for the study is still considered appropriate, given current
techniques and technology.
(4) Whether construction, filling, and other development in the floodplain have made
the maps obsolete.
(5) If any of the flood studies or floodplain maps credited under this activity are not
current, what needs to be done to bring them up to date (e.g., restudy a stream
where the watershed has undergone a lot of development, revise a study to reflect a
revised official precipitation data publication, or conduct a new study where a
bridge has been replaced).
If any of the community’s flood studies or floodplain maps are not current, the engineer
must identify what needs to be done to bring them up to date, e.g., restudy a stream where
the watershed has undergone a lot of development, revise a study to reflect a revised
official precipitation data publication, or conduct a new study where a bridge has been
replaced.

k. Special hazards regulations (SH) (Credit points vary.)
Credit for regulating areas subject to special flood-related hazards is described in
the separate publications on special hazards.
The CRS encourages communities to devote special attention to areas affected by the special
flood-related hazards listed in Section 401. Communities affected by one or more of these
hazards must obtain a copy of the appropriate publication (see Appendix E), which shows
how to increase credit points for regulating development in areas affected by these special
hazards.
Example 431.k-1. Floodville manages Foster Creek's 500-year floodplain for ice
jam hazards. Using the publication CRS Credit for Management of Ice Jam Hazards,
it determines its credit . As explained in the example in that publication, cSH = 16.92.
l. State-mandated regulatory standards (SMS) (Maximum credit: 45 points)
SMS = the sum of the following:
1.
Floodplain management regulatory standards (maximum credit: 25 points):
0.1 x the equivalent credit for each state-mandated regulation credited in the
400 series of CRS activities.
2.
Insurance agent training (maximum credit: 20 points):
(a)
5, if the state mandates that property insurance agents must attend at
least one hour of training per year on flood insurance as a condition
of obtaining or maintaining their license.
(b)
10, if the mandate is for two hours of flood insurance training.
(c)
20, if the mandate is for three or more hours of flood insurance training.
This element recognizes the benefit received by the NFIP for a state-required measure that is
implemented in both CRS and non-CRS communities in that state. State-mandated regulations
also benefit from better staff training and state oversight than other regulatory provisions.
A community should contact the ISO/CRS Specialist to obtain its SMS credit. The credit may
apply differently to different communities within a state, depending on the requirement. For
example, only coastal communities receive SMS credit for a state requirement for a coastal
setback line.

There is no credit if the activity is not verified locally. Examples of possible submittals
include, but are not limited to:
•
State-mandated freeboard,
•
State floodway mapping standards, and
•
State coastal setback regulations.
Example 431.l-1. Floodville’s state requires a floodway mapping standard of a
0.5-foot allowable surcharge and Floodville’s floodways were calculated to this
standard. The equivalent credit for this under Activity 420 (Additional Flood Data),
Section 411.c, More Restrictive Floodway Standard (FWS), is 100 points.
SMS = 0.1 x 100 = 10
m. Building code (BC) (Maximum credit: 190 points)
BC = the sum of the following. These credits are reduced if the community adopts
only parts of each code or if the community adopts a stand-alone floodplain
management ordinance instead of adopting the flood provisions (including ASCE
24) of the International Code Series (I-Codes).
1. 15 x (7 - BCEGS) where BCEGS is the class attained by the community under
the Building Code Effectiveness Grading Schedule. There is no credit for
BCEGS classes 7, 8, 9, or 10.
2. Up to 100 points for adopting a complete set of the codes. This credit is the

Even though a CRS community has been deemed to be in full compliance with the NFIP, it
may not have a building code. Many communities meet their NFIP obligations through a
stand-alone ordinance that may be administered by the zoning, planning, engineering, or
other office, separate from the building department. A floodplain management program can
work without a code, but implementation may not be as effective.
Coordinating floodplain management with a local building code has several advantages,
which are summarized in Figure 430-2. Because of these advantages, the CRS provides credit
for building codes in two ways: crediting the community’s Building Code Effectiveness
Grading Schedule (BCEGS) classification and recognizing those communities that have
adopted the current editions of the appropriate codes.
BCEGS: A community must adopt and enforce a building code to qualify for a CRS class 7
or better (see Sections 211.b and c). The BCEGS, developed and operated by the Insurance
Services Offices, Inc. (ISO) assesses the building codes in effect in a community and how a
community enforces them, with special emphasis on mitigation of losses from natural
disasters.
The insurance industry began the BCEGS project after determining that the catastrophic
losses from Hurricane Andrew were compounded by poor building code enforcement. The
insurance goal is that the prospect of lessening catastrophe-related damage (and ultimately
lower insurance costs) provides an incentive for communities to enforce their building codes
more rigorously.
In its BCEGS program, ISO assigns each community a grade of 1 (best) to 10 (no recognized
program). Ratings are based on community answers to an extensive mailed questionnaire and
a follow-up community verification visit with the cognizant building department by ISO.
BCEGS ratings are provided for all communities that do code enforcement, whether it be for
themselves or for smaller jurisdictions. When a smaller community’s code enforcement
program is administered by a larger jurisdiction, the smaller community will receive the
larger jurisdiction’s classification.
There are two ratings for each jurisdiction, personal (residential) and commercial. If they are
different, the CRS prerequisite and this element’s credit are based on the higher number of
the two ratings. For example, if a community has a class 6 residential BCEGS rating and a
class 5 commercial, the CRS considers it a class 6 BCEGS community.
Under this element, the credit for BC is determined by subtracting the BCEGS class from 7
and multiplying the result by 15. There is no credit for BCEGS classes 7, 8, 9, or 10. For
example, if a community has a BCEGS class 4, BC = 15 x (7 - 4) = 15 x 3 = 45.

Interfaces between Building Codes and Floodplain Management
Permits. The building code is a built-in measure to assure that permits are obtained for structures. The
code can also extend to permits for “other development,” such as requiring permits for grading, paving,
and excavation. In the absence of an “automatic” building permit requirement, it is often difficult for
people to know they are in the floodplain, thereby triggering a floodplain permit. The code requirement
process especially helps capture any rehabilitation, addition, or other improvement, especially in the
case of older buildings, as it relates to substantial improvement requirements to elevate floodplain
buildings.
Inspections. A separate floodplain management ordinance may specify a staff of floodplain inspectors.
However, experience has shown this kind of staff, unless specially trained, would not necessarily be
qualified to assess building practices. A building code usually requires certain mandatory kinds of
inspections that dovetail with inspections for flood purposes (e.g., at the time of a foundation
inspection, which is quite routine per a building code, elevation certifications can be required before
further construction proceeds). The trained eyes of a building inspector are a definite advantage when
looking for construction methods and materials to reduce flood losses, as is required in the NFIP.
Permits for Other Development and Inspector Observations. Although building codes do not
necessarily regulate “other development,” such as grading, paving, or excavation that can result in
increased flood losses, the presence of trained building inspectors in the field, who can observe all
development, is effective in identifying such activities so that action can be taken if needed. Any local
floodplain management program that does not have the benefit of regular building inspectors would
have to establish a comparable field presence.
Post-Flood Inspections. After a flood, there is a strong desire to rebuild. Communities with a building
code and inspectors are generally better able to enforce the permit requirement for damaged buildings
in the floodplain.
Floodplain Management Requirements. A number of NFIP floodplain management requirements
relate to how a building is constructed and what materials are to be used. These areas of construction
are normally governed by building codes. Examples include constructing buildings with foundations
that are anchored to resist flotation, collapse, or lateral movement; use of flood-resistant materials;
placement of utilities and mechanical equipment; and special construction requirements in V Zones.
Having a building code in place will help ensure that these requirements are properly implemented.
Special Certifications. Without the expertise of building inspectors, it is much more difficult for a
community to review special construction-related certifications that are required in the NFIP. These
include floodproofing certifications, certifications of lowest floor elevations (or lowest horizontal
structural members in V Zones), certifications for openings that are designed differently from minimum
NFIP criteria, design and methods of construction of pile and column foundation elements in V Zones,
and breakaway walls in V Zones when the design strength exceeds minimum criteria.
Construction Quality. In the absence of a building code, there is no assurance that buildings placed in
floodplains, even though elevated, will survive. Buildings that are improperly constructed in
floodplains can be subject to significantly more damage than those built to code. Use of improper
materials, unsafe foundations, and inadequate connections are examples of causes for possible failures.
The increased damage will often be paid for either through insurance or disaster aid, thereby working
contrary to good mitigation practices and to CRS principles.
Existing Buildings. Building departments routinely handle permits for existing buildings, yet planning
and zoning departments, which are often responsible for administering community floodplain
management ordinances, rarely deal with proposals to modify sites that are already developed. This has
been known to lead to gaps in enforcement of the substantial improvement and substantial damage
requirements of the NFIP.

If a community is in a state that has does not have a formal BCEGS program, a courtesy
review may be conducted to obtain an equivalent BCEGS class for CRS purposes. More
information on BCEGS can be obtained from ISO through the ISO/CRS Specialists listed in
Appendix G.
Example 431.l-1. Floodville has kept its building code current. Its BCEGS class
is 4 commercial and 5 residential. The 5 is used for CRS credit:
BC = 15 x (7 - 5) = 15 x 2 = 30
I-Codes: The International Code series (I-Codes) includes provisions that address all NFIP
minimum floodplain management requirements. Those NFIP requirements related to the
actual construction of buildings are contained in the bodies of the International Building
Code and International Residential Code. Requirements related to building utilities are
contained in these codes and in the International Plumbing Code, International Mechanical
Code, International Fuel Gas Code, and International Private Sewage Disposal Code. The
other NFIP requirements, such as administrative provisions and requirements that apply to
floodways, subdivisions, and manufactured homes, are contained in Appendix G of the
International Building Code. Communities that adopt the I-Codes have the option of either
adopting Appendix G or addressing these other requirements through a companion ordinance
or regulation.
In the past, the model national building codes have included, to a variable extent, provisions
related to natural hazards, such as seismic hazards, high winds, severe winter storms, and
flood hazards. The I-Codes address all of these hazards on a consistent, rational basis that
allows mitigation of the effects of those natural hazards that are found within each
jurisdiction’s boundaries.
Because of the advantages of incorporating the I-Codes into the community’s floodplain
management program and addressing other hazards, the CRS provides up to 100 points for
adoption of the complete series. To receive full credit, the entire code must be adopted by the
community.
If the following sections are not adopted or are adopted with amendments, the language will
be reviewed to determine the credit:
•
International Building Code: Chapters 3−7, 14−18, and 21−24.
•
International Residential Code: Chapters 3−6, 8, and 9.
In some states, communities are required to adopt state codes or state versions of the I-Codes.
In those cases, the provisions of the mandated code will be compared to the I-Codes and
scored appropriately.

NFPA 5000: The same provisions apply to the NFPA codes. If they are adopted with
amendments, the language will be reviewed to determine the credit.
n. Staffing (STF) (maximum credit: 50 points):
1. STF = 50, if all staff involved in (a) reviewing plans, (b) issuing permits, and
(c) conducting field inspections for floodplain development are
Certified Floodplain Managers (CFMs); OR
2. STF = 25, if all proposed development projects in the floodplain and all final
inspections and project approvals are reviewed and approved by a
CFM; OR
3. STF =
5, for each CFM or graduate of an approved course on managing
floodplain development employed in the office that regulates
floodplain development (up to 25 points). If a CFM also graduated
from the NFIP course, it is counted once as 5 points. This credit is
also provided if the community’s CRS Coordinator is a CFM or a
member of the community’s staff has graduated from the
Emergency Management Institute’s CRS course.
The Association of State Floodplain Managers (ASFPM) and several states have created
floodplain manager certification programs with requirements similar to the EMI course
graduation criteria. More points are provided if the staff person has been certified by ASFPM
(or by a state certification program that has been accredited by ASFPM) because the staff
must fulfill a continuing education requirement to maintain their certification.
Credit under Sections 431.n.1 and 431.n.2. is dependent on the CFMs’ being directly
involved in permit review. A CFM must review each project in the floodplain before it is
permitted and must conduct an inspection or review inspection reports after the project is
completed (e.g., before a certificate of occupancy is issued). The CFM may be a consultant or
employee of a regional agency. The credit is provided as long as no new floodplain
development project is used or occupied without the review and approval of a CFM.
If the head of the regulatory office is (1) responsible for all permits issued, (2) is a CFM, and
(3) establishes procedures that ensure that all floodplain development projects are properly
constructed, then the community would qualify for the 25 points under Section 431.n.2.
Otherwise, if some members of the regulatory staff are CFMs, but some floodplain
development projects are approved by non-CFMs, then 5 points are provided for each CFM
on staff.
This credit will be removed if the staff person leaves the community or does not maintain his
or her certification.
Five credit points are provided under this element if the staff responsible for floodplain
permits have graduated from the “Managing Floodplain Development through the National
Flood Insurance Program” course at the Emergency Management Institute (EMI), the four- or
CRS Coordinator’s Manual

Higher Regulatory Standards
five-day field-deployed version of this course, the home study version, or other equivalent
training. If a CFM also graduated from the NFIP course, it is counted once as 5 points.
Other courses on local floodplain management topics can be submitted for approval. These
could include the EMI courses “Residential Coastal Construction,” “Advanced Floodplain
Management Concepts,” or the field-deployed versions, and state sponsored classes. Courses
of less than four or five days receive pro-rated credit (e.g., an approved two-day course on
floodplain management will typically receive two points). A list of courses approved for CRS
credit is posted on the CRS Resource Center website listed under Activity 430.
The credit for training is based on the number of courses taken. If two people take the
“Managing Floodplain Development” course, the community receives 10 points, the same
credit provided if one person took both the “Managing Floodplain Development” and
“Coastal Construction” courses. If a CFM took the Coastal Construction course, it is worth 10
points. More information on EMI courses can be found in Section 435.
The maximum credit under Section 431.n.3 is 25 points for any combination of CFMs or EMI
course graduates. The only way to get more than 25 points for STF is if all regulatory staff
are CFMs (Section 431.n.1).
If the community is seeking credit for having the person responsible for floodplain permits
graduated from EMI’s floodplain management course, a copy of the certificate of graduation
must be provided. It should be noted that an EMI certificate of ATTENDANCE is not sufficient.
An EMI CERTIFICATE OF GRADUATION is provided only if the student passed the final
examination.
Example 431.n-1: Someburg has one person handling all floodplain
management activities. That person becomes and stays certified: 50 points.
Example 431.n-2: Gulf Beach County has five people involved in building and
development permitting. Two are certified and one of the others has been to the EMI
coastal construction course. Procedures require that one of the CFMs review all
proposed projects in the SFHA and review the final inspection report before a
certificate of occupancy is issued. The score would be 25 + 5 for the two CFMs and
5 for the EMI graduate. The community would receive 25 + 5 + 5 = 35 points.
o. Manufactured home parks (MHP) (Maximum credit: 50 points)
1. Prerequisites:
(a) The community has one or more existing manufactured home parks or
subdivisions in its regulatory floodplain.
(b) Base flood elevations are greater than three feet deep in the parks or
subdivisions.
CRS Coordinator’s Manual
430-21
Edition: July 2007
Higher Regulatory Standards
2. MHP = 50,
if regulations require that new and replacement manufactured
homes placed in existing manufactured home parks or
subdivisions be properly anchored and elevated to or above the
base flood elevation plus any required freeboard.
An “existing manufactured home park or subdivision” is a park or subdivision that was
established before the adoption of floodplain management regulations by the community. The
NFIP regulations (44 CFR 60.3(c)(12)) allow communities to site manufactured homes in
existing manufactured home parks or subdivisions on reinforced piers or other foundation
elements that are not less than 36 inches above grade. In some cases this results in
manufactured homes elevated above the base flood elevation, but where flooding is deeper
than three feet, it exposes them to substantial damage.
This element credits regulations that do not differentiate between manufactured homes and
conventional “stick built” buildings or between existing and new manufactured home parks
and subdivisions. However, the prerequisites limit this credit to those communities that have
existing manufactured home parks where the base flood is greater than three feet deep. In
other words, the credit is limited to those communities where these regulations will have an
impact. Because of this, there is no impact adjustment for this element.
This ordinance language was a requirement of the NFIP before 1989. When communities
were given the option of the 3-foot standard, many kept the higher standard and did not revise
their regulations. The creditable language is also included in the new International Building
Code. Therefore, it is possible that a community’s current ordinance already has the language
that is credited by this element.
p. Coastal AE Zones (CAZ) (Maximum credit: 650 points)
1.
Prerequisites:
(a) The community must have a coastal floodplain on the Atlantic, Gulf of
Mexico, Pacific, or Great Lakes coasts.
(b) This credit is not available in a V Zone because it credits regulatory
standards that are minimum NFIP requirements for V Zones.
(c) The community must map or otherwise designate its coastal AE Zone. The
coastal AE Zone is the coastal SFHA that is not mapped as V Zone. A
community may declare all of its coastal SFHA inland from the V Zone as
coastal AE Zone (as may be the case for a barrier island) or it may use
some other standard, such as identifying all areas where breaking waves
are higher than one foot.
2.
The credit for this element is in addition to the community’s credit for enclosure
limits (ENL) under Section 431.h.
CRS Coordinator’s Manual
430-22
Edition: July 2007
Higher Regulatory Standards
CAZ = the total of the following points:
(a) 500, if all new buildings in the coastal AE Zone must meet the requirements
for buildings in V Zones and for openings in A Zones (44 CFR 60.3(e) and
60.3(c)(5)). If only some of the V-Zone regulations are enforced in the
coastal AE Zone, the points are prorated as follows:
(1) 225, if all of the following V-Zone foundation standards (found in 44
CFR 60.3(e)) are required by the community:
(a) New construction and substantial improvements are elevated on
piles and columns (§60.3(e)(4));
(b) The pile or column foundation and the structure attached thereto are
anchored to resist floatation, collapse, and lateral movement due to
the effects of wind and water loads (§60.3(e)(4)(ii));
(c) New construction and substantial improvements have the space
below the lowest floor free of obstruction or enclosed with nonsupporting breakaway walls, open wood lattice work, or insect
screening (§60.3(e)(5)), and have openings (§60.3(c)(5)); and
(d) Use of fill for structural support is prohibited (§60.3(e)(6)).
(2) 100, if the bottom of the lowest horizontal structural member and the
electrical and mechanical equipment servicing the building must
be elevated to or above the base flood elevation (§60.3(e)(4)(i));
(3) 125, if a registered professional engineer or architect must develop or
review the structural design, specifications, and plans and certify
that the designs and methods of construction to be used meet
accepted standards of practice for meeting the provisions of
§60.3(e)(4)(ii) and breakaway walls (§60.3(e)(5)).
(4) 25, provided all new construction is located landward of the reach of
mean high tide (§60.3(e)(3)). These points are available only if
the designated area includes shoreline).
(5) 25, if the community prohibits human alteration of ANY sand dunes or
mangroves that would increase flood damage (§60.3(e)(7)).
These points are available only if the designated areas include
sand dunes or mangroves.
(b)
EITHER
(1) 150, if regulations prohibit any building enclosures, including solid
breakaway walls, below the base flood elevation; OR
(2) 50, if regulations prohibit enclosures of areas of 300 square feet or
greater, including breakaway walls, below the base flood
elevation. The area enclosed must still meet all NFIP requirements for openings, anchoring, and flood-resistant materials.

FEMA has concluded that its criteria for construction in A Zones do not provide adequate
protection in coastal AE Zones subject to wave effects, velocity flows, erosion, scour, or
combinations of these forces. Wave tank studies conducted by FEMA show that breaking
waves lower than the 3-foot criterion used to designate VE Zones can cause considerable
damage. Post-disaster evaluations and insurance claims data also support this conclusion,
particularly for those buildings with enclosures below the elevated floor. FEMA’s new
Coastal Construction Manual strongly encourages use of some or all of the VE Zone
construction methods in coastal AE Zones, depending on the hazard. A handout providing
information about coastal A Zones is shown in Figure 430-3.
Credit under Section 430.p.2(a)(2) can be given where the top of the lowest floor is used as
the reference point and the community regulations require two or more feet of freeboard in
the coastal AE zone. However, a community cannot receive both freeboard (FRB) and CAZ
credit for the same two feet of freeboard. To receive freeboard credit the community would
need to prorate the credit for freeboard greater than two feet for the area in the regulated
coastal AE Zone.
This element has an impact adjustment. Therefore, coastal communities can only receive the
maximum 650 points if their entire regulatory floodplain (aRF) is treated as a VE Zone.
Example 431.p-1. Gulf Beach County’s floodplain regulations state that all lands
seaward of the Coastal Highway shall be considered V Zones for building protection
purposes. It also states that no new buildings or substantial improvements seaward
of the Coastal Highway shall have enclosures below the level of the base flood
elevation plus two feet.
CAZ = 500 + 150 = 650.
Note that the credit for CAZ will be multiplied by the impact adjustment so the final
credit (cCAZ) will reflect how much of the County’s regulatory floodplain is affected
by these regulations.
432 Impact Adjustment
The area affected by a regulatory standard must exclude areas designated as open
space that are receiving OS credit under Activity 420 (Open Space Preservation).
There is no impact adjustment for the following elements:
Section 431.l State-mandated regulatory standards (SMS)
Section 431.m Building code (BC)
Section 431.n Staffing (STF)
Section 431.o Manufactured home parks (MHP).

Mapping Coastal A Zones
Recent post-storm investigations have shown that typical A-Zone construction
techniques (e.g., wood-frame, light-gauge steel or masonry walls on shallow footings
or slabs, etc.) are subject to damage when exposed to less than 3-foot breaking waves, which is
the current threshold for V-Zone conditions. Accordingly, FEMA and the Community Rating
System encourage communities to map the areas subject to damaging waves and velocities and
enact special regulations for new
construction in those areas.
For the purposes of the CRS, these
areas are called coastal A Zones.
Regulating the area is optional and
credited under Activity 430 (Higher
Regulatory Standards), Section
431.p.
Coastal A Zones have not been
shown on Flood Insurance Rate Maps
(FIRMs) or mentioned in a community’s Flood Insurance Study Report.
Therefore, the exact boundary of a coastal A Zone is determined by the community. At a
minimum, it should include all areas subject to waves of 1.5 feet in height or more.
In some cases, FEMA’s advisory flood recovery maps
show the area subject to such waves. An example from the
Mississippi Gulf Coast is shown to the right. Some new
FIRMs will delineate the “limit of moderate wave action.”
In other cases, the community may want to use a readily
identifiable feature as its boundary. For example, because
Hurricane Katrina flooded areas inland well beyond the
map to the right, the community could play it safe and
declare all land between Railroad Street and the Gulf as
coastal A Zone for informational purposes and/or for
special coastal high hazard area construction standards.
Additional technical guidance on mapping coastal A Zones
can be found in Design and Construction in Coastal A
Zones at http://www.fema.gov/library/viewRecord.do

The impact adjustment for Section 431.e, protection of critical facilities (PCF), is based
on the area of the 500-year floodplain.
a. Option 1:
1.
If new development within the entire area of regulated floodplain (aRF) is
regulated by an element, and no credit was requested for OS in Activity 420,
the impact adjustment ratio for that element = 1.0 (rXXX = 1.0).
2.
If new development within the entire area of regulated floodplain (aRF) is
regulated by an element, and credit was requested for OS in Activity 420, the
impact adjustment ratio for that element = 1.0 - rOS (rXXX = 1.0 - rOS).
The elements in this activity are usually implemented throughout the floodplain. Where this is
the case, the community should use Option 1. Unless the community has applied for credit
under Activity 420 (Open Space Preservation), the applicant can fill in the blanks on the
activity worksheet for the “r” variables with “1.0.” If the community requested credit for OS
in Activity 420, the impact adjustment ratios under Option 1 are reduced by rOS.
Note that some elements are not enforced throughout the floodplain or for all types of
development. For example, there is no credit for protecting storage capacity (PSC) in V
Zones and some ordinances do not require freeboard (FRB) for floodproofing nonresidential
buildings. In these cases, Options 2 or 3 must be used.
Example 432.a-1.
1. Watertown enforces its lower substantial improvement threshold (LSI)
throughout its regulatory floodplain. Watertown did not apply for open space
preservation credit under Activity 420. Under Option 1, rLSI = 1.0.
2. Floodville enforces its regulation to preserve storage capacity (PSC) throughout
its regulatory floodplain. Floodville applied for open space preservation credit
under Activity 420. As shown in the example in Section 422.c, rOS = 0.22. Under
Option 1, rPSC = 1.0 - rOS = 1.0 - 0.22 = 0.78.
b. Option 2:
1.
If new development within part of the area of regulated floodplain (aRF) is
regulated by an element, default values of 0.25 may be used for the impact
adjustment ratios (rXXX = 0.25).
2.
For coastal AE Zone credit (CAZ), under option 2, rCAZ = 0.1.
CRS Coordinator’s Manual
430-26
Edition: July 2007
Higher Regulatory Standards
Where the standard is enforced in only some of the regulatory floodplain, the community
must use either Option 2 (the default value) or Option 3. The community may use Option 2 if
it results in more points than Options 1 or 3 (e.g., if more than 75% of the regulatory
floodplain is preserved as open space, rOS > 0.75 and Option 2 would provide more credit
than Option 1).
Example 432.b-1. Someburg has some open space and requires freeboard only
for residential buildings. Rather than prepare an Impact Adjustment Map, Someburg
uses Option 2 for Activity 430:
rFRB = 0.25
c. Option 3:
The impact adjustment ratio for each element is computed by dividing the area
affected by the area of the regulatory floodplain (aRF).
1. rFRB = aFRB
aRF
2. rFDN = aFDN
aRF
3. rCSI = aCS I
aRF
4. rLSI = aLSI
aRF
5. rPCF = aPCF, where a500 = the area of
a500
the 500-year floodplain
6. rPSC = aPSC
aRF
7. rNBR = aNBR
aRF
9. rOHS = aOHS
aRF
10. rCAZ = aCAZ
aRF
8. rENL =
aENL
aRF
The area affected by a regulatory standard must exclude areas designated as open space that
are receiving OS credit under Activity 420 (Open Space Preservation).
If Option 3 is used, each variable for which credit is requested must be appropriately
designated on the Impact Adjustment Map described in Section 403. In many communities,
these regulatory standards will be applicable throughout the community’s floodplains, so a
note on the key will be adequate.
Where an element applies differently to different areas, the impact adjustment ratios for each
area must be computed separately.

Example 432.c-1. See Figure 430-3. Floodville's regulation requiring a landscaping plan is only in effect in the bottomland portion of the floodplain. The
bottomlands are marked "NB" in the City's park where they receive open space
credit.
They are marked "NBR" outside of the park where future development is subject to
the regulation. The area of the bottomlands outside of the park, aNBR, is 91 acres.
rNBR = aNBR = 91 = 0.23
aRF
396
If Floodville used Option 2, rNBR = 0.25 - (0.25 x rOS) = 0.25 - (0.25 x 0.22) = 0.25 0.06 = 0.19. rNBR will be smaller under Option 2, so Floodville uses Option 3, and
rNBR = 0.23.
Example 432.c-2. See Figure 430-4. Watertown requires 2 feet of freeboard
(FRB2) in the Riley River floodplain. This is the entire mapped regulatory floodplain,
so aFRB2 = aSFHA = 0.43 square miles. The City requires 1 foot of freeboard on the
tributaries. These are marked FRB1 on the Impact Adjustment Map. aFRB1 = 0.09.
aRF for Watertown = 0.52.

During the verification visit, the ISO/CRS Specialist reviews a sample of 10 recent
developments and discovers that one of the 10 received a variance from the PSC
requirement. Credit for PSC is reduced by 1/10 from 80 to 72. The Specialist also
noted that the value for rOS was changed from 0.22 to 0.21 when Activity 420 was
verified. This increases the value for rPSC from 0.78 to 0.79. Floodville's verified

the ordinance or statute has been enacted and is being enforced (see Section 212.a).
The community must have the following documentation available to verify
implementation of this activity:
b. [If the community determines impact adjustment ratios using Option 3 (Section
432.c)] The Impact Adjustment Map prepared in accordance with Section 403. Each
area for which an impact adjustment ratio is calculated must be designated on the
Impact Adjustment Map and in the map's key.
c. An explanation of the procedures followed for enforcement of the regulatory
standard and copies of relevant permit records.
d. [If applying for credit for staffing under Section 431.n] A copy of the certificate of
graduation or floodplain manager certification must be provided.
For freeboard (FRB), the community should explain its general building permit inspection
process, demonstrating that this process ensures that structures are actually protected to the
level required by the ordinance. Relevant permit records would include elevation certificates
and floodproofing certificates that show the level to which the building is protected.
For cumulative substantial improvements (CSI), the community must demonstrate that its
permit process tracks permits for a structure to ensure that the regulatory requirement is met.

Higher Regulatory Standards
Increased Cost of Compliance
On June 1, 1997, the NFIP began offering “Increased Cost of Compliance” (ICC) coverage for
buildings covered under the Standard Flood Insurance Policy (SFIP). ICC coverage provides for
the payment of a claim to help pay for the cost to comply with community floodplain management
ordinances after a flood event in which a building has been declared substantially damaged or
repetitively damaged.
When an insured building is damaged by a flood and the community declares the building to be
substantially or repetitively damaged, ICC will help pay for the cost to elevate, floodproof,
demolish, or relocate the building up to a maximum of $30,000. This coverage is in addition to
the building coverage for the repair of actual physical damage from flood under the SFIP. An ICC
claim can be filed whether or not a community has received a Presidential disaster declaration.
The following conditions must be met for a substantially damaged building to be eligible for
an ICC claim: A building is eligible for an ICC claim payment if it is in a Special Flood Hazard
Area and if the community determines it has been damaged by a flood whereby the cost of
restoring the building to its before-damaged condition would equal or exceed 50% of the market
value of the building before the damage occurred, as determined by the community. All NFIP
communities must have, at a minimum, a substantial damage provision in their floodplain
management ordinance in accordance with the NFIP criteria.
The Flood Insurance Reform Act of 2004 expanded the definition of what qualifies as substantial
damage. Section 105(b)(4) of the Act reads, “the term ‘substantially damaged structure’ means a
structure covered by a contract for flood insurance that has incurred damage for which the cost of
repair exceeds an amount specified in any regulation promulgated by the Director, or by a
community ordinance, whichever is lower.” After FEMA regulations are published to implement
this provision, regulations with substantial damage thresholds lower than 50% that qualify for LSI
credit may also be able to trigger ICC claim payments. Communities with LSI credit should check
with their FEMA Regional Offices (Appendix A) to confirm this.
The following conditions must be met for a repetitively damaged building to be eligible for
an ICC claim payment: A building is eligible for an ICC claim payment if it is in a Special
Flood Hazard Area and is a repetitive loss structure and is subject to a community floodplain
management ordinance. Two conditions must be met for an ICC claim to be paid under the SFIP
for a repetitive loss structure:
1. The state or community must have adopted and be currently enforcing a repetitive loss
provision or a cumulative substantial damage provision requiring action by the property owner to
comply with the community’s floodplain management ordinance, and
2. The building must have a history of NFIP claim payments that satisfies the statute’s definition
of “repetitive loss structure.” A repetitive loss structure means “a building covered by a contract
for flood insurance that has incurred flood-related damage on 2 occasions during a 10-year period
ending on the date of the event for which a second claim is made, in which the cost of repairing
the flood damage, on the average, equaled or exceeded 25% of the market value of the building at
the time of each such flood event.” Note that this statutory ICC definition is not the same as the
CRS definition of a repetitive loss property.
Figure 430-6a. Increased Cost of Compliance flood insurance coverage.
CRS Coordinator’s Manual
430-36
Edition: July 2007
Higher Regulatory Standards
Increased Cost of Compliance (cont.)
The date on which the first loss occurred, even if the loss occurred before June 1, 1997, is
immaterial to eligibility for an ICC claim payment, as long as the state or community enforced a
repetitive loss or cumulative substantial damage requirement on the building and the insured
building satisfies the definition of the “repetitive loss structure” defined above.
CRS N OTE : Communities receiving CSI credit for a cumulative substantial improvement
regulation must be aware that there may be instances in which the community’s criteria may
require compliance with its floodplain management ordinance, but the building may not qualify
for an ICC claim payment (e.g., if a building is damaged three times, with each flood averaging
20% damage).
Below are two options for ordinance language that is consistent with the definition of “repetitive
loss structure” under the NFIP. The language would receive 20 points under CSI—fewer points
than the more restrictive language of Sections 431.c.1(a) and (b).
Additional guidance on ICC coverage can be found in Increased Cost of Compliance Coverage:
Guidance for State and Local Officials, FEMA 2003.
Option 1:
A. Adopt the Following Definition:
“Repetitive loss” means flood-related damage sustained by a structure on two separate occasions
during a 10-year period for which the cost of repairs at the time of each such flood event, on the
average, equals or exceeds 25% of the market value of the structure before the damage occurred.
B. And modify the “substantial improvement” definition to read as follows:
“Substantial improvement” means any reconstruction, rehabilitation, addition, or other
improvement of a structure, the cost of which equals or exceeds 50% of the market value of the
structure before the “start of construction” of the improvement. This term includes structures that
have incurred “repetitive loss” or “substantial damage,” regardless of the actual repair work
performed.
Option 2: Modify the “substantial damage” definition to read as follows:
“Substantial damage” means damage of any origin sustained by a structure whereby the cost of
restoring the structure to its before-damage condition would equal or exceed 50% of the market
value of the structure before the damage occurred. Substantial damage also means flood-related
damage sustained by a structure on two separate occasions during a 10-year period for which the
cost of repairs at the time of each such flood event, on the average, equals or exceeds 25% of the
market value of the structure before the damage occurred.
N OTE : An ICC claim payment is ONLY made for flood-related damage. The substantial damage
part of the definition must still include “damage of any origin” to be compliant with the minimum
NFIP floodplain management regulations.

Summary of Activity 440
441
Credit Points. There are four elements in this activity for a maximum of 239 points (excluding
special hazards credit).
a.
Additional map data (AMD): Up to 129 points are provided for implementing digital or paper
systems that improve access, quality, and/or ease of updating flood data within the community. Each
system must be used by the local regulatory staff on a regular basis. The data in the system must be
updated at least annually.
b.
Benchmark maintenance (BMM): Up to 90 points are provided for a program that maintains
benchmarks so surveyors can find them and can depend on them to be accurate.
c.
Erosion data maintenance (EDM): Points are provided for maintaining coastal erosion data as
described in CRS Credit for Management of Coastal Erosion Hazards.
d.
FIRM maintenance (FM): Up to 20 points for maintaining copies of all Flood Insurance Rate Maps
(FIRMs) that have been issued for the community.
442
Impact Adjustment. The credit points for each element are adjusted in one of three ways.
a.
Under Option 1, if the program is implemented throughout the Special Flood Hazard Area (SFHA),
the impact adjustment ratio for an element is 1.0.
b.
Under Option 2, if the program is not implemented throughout the SFHA, a default impact adjustment
ratio of 0.25 may be used.
c.
Under Option 3, if the program is not implemented throughout the SFHA, the impact adjustment
ratios may reflect the proportion of the SFHA affected.
443
Credit Calculation. The credit points for each element are multiplied by the impact
adjustment ratios and the products are totaled.

Flood Data Maintenance
440 FLOOD DATA MAINTENANCE
Credit is provided for making the community’s floodplain maps more current, useful, or
accurate in order to improve local regulations, planning, disclosures, and property
appraisals.
Background: Outdated mapping hinders good floodplain management. A Flood
Insurance Rate Map (FIRM) can and should be updated frequently to account for study
revisions, site-by-site analyses, better ground elevation data, annexations, and
incorporation of new hazard data. To keep a FIRM updated at minimal cost, the
Department of Homeland Security’s Federal Emergency Management Agency (FEMA)
publishes Letters of Map Revision. However, these do not provide local officials and
other map users with a meaningful picture of the floodplain.
Activity Description: Under this activity, credit is provided for putting National Flood
Insurance Program (NFIP) FIRM and Flood Boundary and Floodway Map delineations
on a digitized mapping system or other method that allows quick revision and reprinting
of a floodplain map. Flood hazard data could also be maintained on computerized
parcel records. This activity also includes credit for adding and/or maintaining
benchmarks and overlaying the community’s floodplain mapping (including the FIRM)
on the zoning map, the assessor’s map, or other map used regularly by community
staff.
A computerized parcel system is often easier to use than a map. With such a system, a
building official, real estate agent, or anyone interested in the flood hazard on a property can
quickly find data such as flood zone number, flood elevations, and lowest floor elevation. In
most cases, flood data are maintained for a community’s entire floodplain. Where this is not
the case, the areas affected must be adjusted by an impact adjustment ratio based upon the
area of regulated floodplain with the community.
Maintaining current benchmarks makes it easier and less expensive for developers and
property owners to determine ground, floor, and base flood elevations for construction and
flood insurance purposes.
NOTE: This activity only credits maintenance of the community’s regulatory flood data. The paper
FIRM is still the document used for flood insurance rates and the mandatory purchase requirement.
However, if the community’s flood data maintenance program finds an error in the FIRM, it should
be reported to FEMA so it can be included in the next map revision. If the error would remove a
property from the SFHA, it is assumed that the owner will be motivated to request a map
amendment.
CRS Coordinator’s Manual

Edition: July 2007
Flood Data Maintenance
441 Credit Points
Maximum credit for Activity 440: 239 points.
a. Additional map data (AMD) (Maximum credit: 129 points)
This element credits digital or paper systems that improve access, quality, and/or
ease of updating flood and FIRM data.
1. Prerequisites.
(a) The system must be used regularly by the community regulatory staff.
(b) New data, including annexations, new subdivision maps, flood insurance
restudies, letters of map revision, letters of map amendment, and studies
performed for site-specific analyses, must be added at least annually to the
data base or overlay map.
(c) Digitized data must be made available annually to FEMA at no cost (if
requested).
Three different types of flood data maintenance systems are usually eligible for credit:
•
Map overlays, such as overlaying the regulatory floodplain on the zoning map, aerial
photograph, or more detailed street map; or using clear plastic sheets over the FIRM to
record map changes.
•
A geographic information system (GIS), computer aided design (CAD), or other
digitized system that updates information electronically and can display or print a
current map.
•
A database management program for parcel records that maintains the appropriate
flood data for each property. Some communities have master parcel record systems
that can be accessed for building permit records, property tax information, FIRM data,
and other purposes. Sometimes these systems are tied into a GIS. Credit is given if
parcels in this system are designated as “in” or “out” of the floodplain.
Data available from these three systems improve the community’s administration of its
floodplain management program. Credit is dependent on the map data being used in the
community’s regulatory program. There is no credit for a map system that is used only for
planning drainage projects or other non-regulatory purpose. The objective of this requirement
is to encourage more community offices to be familiar with the local flood problems and to
reduce the likelihood that land use or development decisions will be made without
CRS Coordinator’s Manual
440-3

Flood Data Maintenance
considering the hazard. Using the system to provide map determinations to the permit office
is considered a regulatory purpose.
The data from a digitized mapping or parcel system must be provided to FEMA if it is
requested. A fee may be charged to other requestors based on the actual cost of retrieval or
reproduction.
The Community Rating System (CRS) encourages communities to devote special attention to
areas affected by the special flood-related hazards listed in Section 401. Communities
affected by one or more of these hazards should obtain a copy of the appropriate CRS
publication (see Appendix E), which shows how to increase credit points for regulating
development in areas affected by these special hazards. Regulating such areas is a
prerequisite to receiving credit for including the area in this activity.
2. Credit points: AMD = the total of the following points based on the types of data
included in the data maintenance system, except that no credit is provided
unless item (a) is included:
(a) 32, for showing the regulatory floodplain boundaries, corporate limits,
streets, and parcel or lot boundaries (a database management program
must show whether a parcel is in the regulatory floodplain);
(b) 15, for a GIS layer that shows buildings, building outlines, or building
footprints (a database management program must show whether the
primary building on the lot is in the regulatory floodplain), and the
building data is kept up to date to reflect new construction;
(c) 8, for showing floodways or coastal high hazard areas (a database
management program must show whether either the parcel or the
primary building is in the floodway or coastal high hazard area);
(d) 8, for showing base flood elevations;
(e) 6, for including FIRM zone attributes (e.g., A3, VE, etc.);
(f) 8, for showing the 500-year floodplain elevations or boundaries (a
database management program would show whether the parcel is in
the 500-year floodplain);
(g) 8, for showing areas of the community subject to other natural hazards (a
database management program would show whether the parcel is
subject to another hazard);
CRS Coordinator’s Manual
440-4
Edition: July 2007
(h) EITHER:
(1) 10, if the community’s GIS includes topographic contour lines; OR
(2) 20, if the system includes topographic contour lines at a smaller contour
interval than that provided on available U.S. Geological Survey digital
orthophoto quarter quads (DOQQ);
(i) 8, for including updated floodplain data in the tax assessment data base;
(j) 8, for including overlays or layers for all FIRMs in effect after the date of the
community’s application to the CRS; and
(k) 8, for other overlays or databases used for regulation or mitigation
programs, including incorporating and maintaining layers from HAZUSMH and the community’s repetitive loss areas.
Most of the credited items are important to provide the regulatory staff the latest FIRM data
for a property. The CRS wants to encourage users of the community’s system, including tax
assessors and property appraisers, to be aware of the flood hazard. The CRS also wants to
encourage keeping old FIRMs to help track substantial improvement requirements and
eligibility for grandfathered flood insurance premiums. Old maps are hard to obtain, so
keeping them on record would provide a valuable service to residents.
Item 2(g) credits showing areas of the community subject to other natural hazards. Local
permitting and planning should be aware of all hazards to which a property is exposed. These
could include landslide-prone areas, areas subject to subsidence or stream migration, and
areas with soils unsuitable for septic fields. Including these hazards in GIS layers that are
seen when permits are reviewed or when plans are being drafted will remind everyone
involved of the need to protect people and property from those hazards.
For item (h), credit is provided for including a layer with contour lines in the community’s
GIS. If the layer has contour intervals smaller than what is available from the U.S. Geological
Survey’s DOQQs, then 20 points are provided. In those areas where there are no DOQQs, the
credit is provided if the contour interval is smaller than that on the area’s USGS quadrangle
maps.
HAZUS-MH (Hazards U.S.–Multi-Hazard) is FEMA’s standard, nationally applicable
methodology and software program for estimating potential losses from earthquakes, floods,
and hurricane winds. HAZUS-MH uses ESRI’s ArcGIS geographic information system
software platform to analyze, map, and display potential damage and losses. The CRS
encourages the use of HAZUS-MH to promote a greater understanding and awareness of
hazard risk and for keeping the HAZUS-MH database updated. See Figure 510-1 for more
information on HAZUS-MH.)

Flood Data Maintenance
Identifying and mapping the community’s repetitive loss areas is discussed in Sections 502
and 503. A repetitive loss community must also develop a list of addresses of the improved
properties in its repetitive loss areas. This work can be greatly facilitated by the use of a GIS.
Once a repetitive loss area layer is developed, it should be used during mitigation planning
and other activities focused on reducing the community’s flood problems.
NOTE: If a community maintains data on its repetitive loss properties, it must be remembered
that such data may be subject to the Privacy Act. Information such as the names of people
and addresses of properties that have received repetitive flood insurance claims and the
amounts of such claims may only be used by the community in furtherance of local flood loss
reduction. Communities are prohibited from releasing such information to the public and
from using it for solicitation or other purposes. Such information should be marked “For
internal use only. This information is legally privileged and confidential. Its use is protected
by the Privacy Act of 1974.” Generic information, such as total claim payments for an area
or data not connected to a particular property, may be made public.
Example 441.a-1. Floodville has overlaid the regulatory floodplain and floodway
boundaries, with base flood elevations, onto the zoning and land use plan maps
used to administer the zoning ordinance, the building and health codes, and the
regulations for new subdivisions. The maps are updated at least annually. The maps
include streets, corporate limits, and parcels.
AMD = 32 + 0 + 8 + 8 + 0 + 0 + 0 + 0 + 0 + 0 + 0 = 48
b. Benchmark maintenance (BMM) (Maximum credit: 90 points)
This element credits a program that maintains benchmarks so surveyors can find
them and can depend on them to be accurate.
1. Prerequisites: credit is provided for each benchmark that meets the following
criteria:
(a) It must be a benchmark that is EITHER:
(1) In the National Spatial Reference System (NSRS) database; OR
(2) A permanent monument with key data posted in a reference system
readily available to local surveyors, such as the community’s website.
(b) There must be a note that is has been recovered within the last five years;
(c) It must be a first- or second-order vertical control benchmark;
CRS Coordinator’s Manual
440-6
Edition: July 2007
Flood Data Maintenance
(d) It must have a stability rating of A or B; AND
(e) It must be within one (1.0) mile of some part of the community’s regulatory
floodplain.
2. Credit points:
(a) NBM = the number of qualifying benchmarks in the community.
(b) NBM = 1.5, if the benchmark is also entered into the National Spatial Reference
System (NSRS) database.
(c) NBM = 15 x NBM ,
aRFM
where aRFM is the area of the community’s regulatory floodplain in square miles.
The National Spatial Reference System (NSRS) is maintained by the National Geodetic
Survey (NGS) in the U.S. Department of Commerce. It is a compendium of vertical and
horizontal benchmarks for the country. This element provides credit for a community’s
having a sufficient number and density of good benchmarks in the NSRS. If the community
does not, it is encouraged to either survey new ones or submit the data necessary to add
qualifying existing benchmarks to the national system.
Any surveyor can create a NSRS benchmark. Surveyors must follow strict NGS guidelines for
the type of monument set and the accuracy of the survey that establishes the horizontal
location of the monument and/or the elevation. After review by the NGS, these benchmarks
are added to the NSRS database, which is available to surveyors and the public on the
internet.
If the community has a network of quality benchmarks that are permanent monuments but are
not entered into the NSRS, it must provide a statement, signed by a licensed surveyor, that
each benchmark for which credit is requested is a monument that would qualify for addition
to the NSRS if it were submitted to the NGS.
“Permanent monuments” are engraved metal discs at least 2 inches in diameter set in concrete
or similar markers that are recognizable, durable, and immovable or steel rods driven to
resistance. Chiseled squares in sidewalks, parts of fire hydrants, nails in telephone poles, “PK
nails” in pavement, etc., are not “permanent monuments.”
For this credit, a benchmark must meet all of the prerequisites:
(1) It must be in the NSRS database, or it must be in a database maintained by the
community or other authority that is readily available to local surveyors. This may be
in the form of a published book or a website. The database must include key data, such
as the location and description of the benchmark, the elevation and datum, and when it
was last recovered.
CRS Coordinator’s Manual
440-7
Edition: July 2007
Flood Data Maintenance
(2) There must be a note that it has been recovered within the last five years. If a
benchmark has not been recovered in the last five years (i.e., no one has confirmed to
NSRS that the site has been found), a local official or surveyor can locate the
monument and report that it has been recovered. In some cases, the community or
local surveyors may need to recover all credited benchmarks to maintain this credit at
each cycle verification visit. Recovery can be reported by any local official—it does
not have to be a licensed surveyor. (The NSRS website explains the process to report
recovery.)
(3) It must be a first- or second-order vertical benchmark. The “order” tells how close the
results were when the surveyor who set the benchmark completed a circuit back to the
starting point. Lower-order benchmarks are not as dependable.
(4) It must have a stability rating of A or B. The NSRS describes whether a benchmark is
likely to move over time with the following system:
A = most reliable and expected to hold an elevation (e.g., bedrock)
B = probably will hold an elevation well (e.g., a massive bridge pier)
C = may hold, but of a type commonly subject to ground movement (e.g., a
building foundation)
D = mark of questionable or unknown stability
Some areas subject to land subsidence may not have any benchmarks rated A or B. If
the community has an alternative way to provide dependable elevation data, it may
submit a description of its alternative. An example would be a program that resurveys
benchmarks every few years.
(5) It must be within one mile of some part of the community’s regulatory floodplain. For
this credit, the community must submit a map showing the location of the qualifying
benchmarks.
Example 441.b-1. Floodville has two vertical control benchmarks that meet the
prerequisites. One is listed in the National Spatial Reference System and the other is
posted on the city engineering department’s website. (NBM = 1 + 1.5 = 2.5). The area of
Floodville’s regulatory floodplain is 396 acres or 0.62 square miles.
BMM = 15 X NBM = 15 X 2.5 = 37.5 = 60.48
ARFM
0.62
0.62
Floodville could increase its credit for BMM to the maximum 90 points if it had four
benchmarks that were entered into the NSRS. It may be that the NSRS has one or two
qualifying benchmarks that would provide the city with this credit if the City simply found
them and reported them as recovered..

Flood Data Maintenance
c. Erosion data maintenance (EDM)
Credit for maintaining coastal erosion data is described in CRS Credit for
Management of Coastal Erosion Hazards. The credit points, EDM, are calculated
separately and transferred to this activity.
This credit is for including coastal erosion rates and similar data in a GIS, digitized parcel
data, or overlay map. More information and credit point calculations can be found in CRS
Credit for Management of Coastal Erosion Hazards (see Appendix E).
d. FIRM maintenance (FM) (Maximum credit: 20 points)
Credit is provided for maintaining earlier editions of flood insurance maps. The
maps must be readily available and the community must allow inquirers access to
them.
FM = the total of the following points:
1. 15, for maintaining copies of all FIRMs, Flood Insurance Studies, and Flood
Boundary Floodway Maps that have been issued for the community. There
is no credit if the FIRM has never been revised.
2.
5, for maintaining copies of all Flood Hazard Boundary Maps that were issued
for the community.
To receive credit under Activity 320 (Map Information Service), the community must
maintain copies of old FIRMs that have been in effect since 1999 or the date the community
applied to the CRS, whichever is later. Under this element, credit is provided for maintaining
copies of ALL FIRMs, i.e., each FIRM that appears on the list of FIRM revisions in the legend
of each FIRM. Keeping the community’s current FIRM is a minimum requirement of the
NFIP, so if the community has only been issued one FIRM, there is no credit under this
element.
Additional credit is provided for maintaining copies of the Flood Hazard Boundary Maps
(FHBMs), i.e., the FEMA maps published before the community received its first FIRM.
This credit is provided for maintaining the FIRMs and FHBMs in paper, microfilm, or other
format. They do not have to be part of the system credited under Section 441.a (AMD).
Copies of old FIRMs and FHBMs may be available from the Map Coordination Contractors
(see Section 445.e).
CRS Coordinator’s Manual
440-9
Edition: July 2007
Flood Data Maintenance
442 Impact Adjustment
Credit for additional map data (AMD) and benchmark maintenance (BMM) are adjusted
according to the portion of the area of regulatory floodplain (aRF) that the element
covers:
a. Option 1:
1. If the data for the entire regulatory floodplain have been entered into the system
or included on the overlay map, rAMD = 1.0.
2. If the credited benchmarks cover the entire regulatory floodplain, rBMM = 1.0.
b. Option 2:
1. If the data for only part of the regulatory floodplain have been entered into the
system or included on the overlay map, the community may use the default
values: rAMD = 0.25.
2. If the credited benchmarks cover part of the regulatory floodplain, the community
may use the default value: rBMM = 0.25.
c. Option 3:
1. The impact adjustment ratio is computed by dividing the area for which data
have been entered into the computer or added to the overlay map by the area of
the regulatory floodplain (aRF):
rAMD = aAMD
aRF
2. The impact adjustment ratio is computed by dividing the area covered by the
credited benchmarks by the area of the regulatory floodplain (aRF):
rBMM = aBMM
aRF
If the program is implemented in only a portion of the regulatory floodplain, the community
may use either Option 2 or Option 3. For example, if a county has only entered flood data for
its urbanized areas into a GIS, it may use the default value rAMD = 0.25, or it may determine
aAMD and aRF to calculate rAMD and designate the areas on its Impact Adjustment Map.
CRS Coordinator’s Manual
440-10
Edition: July 2007
Flood Data Maintenance
Example 442-1. Floodville’s overlay map covers the entire community and
includes all floodplains. Using Option 1, rAMD = 1.0.
If a community has different systems for different areas of the community, it should designate
and score each one separately and the total score will be corrected through the impact
adjustment.
Example 442-2. Gulf Beach County has a GIS for the developed area along the
coast. For inland rural areas, the staff refers to map overlays. The GIS would be
designated “AMD1” and the area not covered by the GIS would be “AMD2.” The two
systems would be scored and, if together they covered the entire county, rAMD1 plus
rAMD2 would equal 1.0.
d. There is no impact adjustment for EDM or FM.
443 Credit Calculation
a. cAMD = AMD x rAMD
b. cBMM = (BMM x rBMM)
c. c440 = cAMD + cBMM + EDM + FM
Example 443-1. As noted above, AMD for Floodville = 48 and rAMD = 1.0.
cAMD = 48 x 1.0 = 48
Floodville’s credit for benchmarks is explained in Example 441.b-1. Because the
system covers the entire regulatory floodplain, option 1 is used and rBMM = 1.0.
cBMM = 60.48 x 1.0 = 60.48
Floodville’s staff cannot find copies of earlier FIRMs: FM = 0.
Floodville has no coastal erosion areas: EDM = 0.
c440 = cAMD + cBMM + EDM + FM = 48 + 60.48 + 0 + 0 = 108.48
CRS Coordinator’s Manual

Flood Data Maintenance
444 Credit Documentation
The community must submit the following:
a. A short summary of all elements of its flood data maintenance program, or a sample
copy of the item for which credit is requested, which clearly shows all of the items to
be credited.
For credit for computerized data, the summary should briefly discuss the computer system
used, the types of data included in the system, access to the data, and how the system is used
for floodplain management. For the other systems, the summary should consist of a short
narrative description of the procedure and how it is used by the community for floodplain
management.
The community must have the following available to verify implementation of this
activity:
b. [If the community calculates impact adjustment ratios using Option 3 (442.c)] The
Impact Adjustment Map discussed in Section 403. Each area listed in Section 441
for which credit is being requested must be shown on the Impact Adjustment Map
and in the key.
c. Copies of the digitized mapping, parcel records, overlay maps, shoreline erosion
records, and/or old FIRMs, as appropriate.
If the community has a GIS or a database management program for parcel records, it should
be able to prepare a printout or a disk with the addresses of all the properties in the
floodplain. This would facilitate mailing its outreach project to floodplain residents (OPF)
under Activity 330 (Outreach Projects).
d. [If the community is applying for credit for maintaining benchmarks (BMM)]
1. The data for the qualifying bench marks that are in the NSRS or the community’s
publicly accessible database. This must include key data, such as the location and
description of the benchmark, the elevation and datum, and when it was last
recovered;
2. For those benchmarks that are not in the NSRS, a statement signed by a licensed
surveyor that states that they meet the element’s prerequisites, and
3. A map showing the locations of the listed benchmarks.
CRS Coordinator’s Manual
440-12
Edition: July 2007
Flood Data Maintenance
The data can be in the form of a printout of the NSRS datasheets, a photocopy of the relevant
pages of the community’s benchmark book, or the URL for the website database. The
surveyor’s statement does not need to be certified or sealed, but does need to include the
signator’s license number. The map can be a street map, a floodplain map, or any map that
facilitates finding the benchmarks on the ground. The NSRS retrieval maps do not qualify
because they do not show or name enough features.
The community must submit the following with its annual CRS recertification:
e. Identification of any benchmarks that appear on the FIRM that were found to be
missing or inaccurate.
If any benchmarks are found to be listed incorrectly, the community should provide FEMA
with the correct elevations or information on other benchmarks. Otherwise, revised FIRMs
will continue to show the incorrect information.

450 STORMWATER MANAGEMENT
Summary of Activity 450
451 Credit Points. There are five elements in this activity for a maximum of 670 points.
a. Stormwater management regulations (SMR): Up to 225 points are provided for regulating developments on a
case-by-case basis to ensure that the peak flow of stormwater runoff from each site will not exceed the
predevelopment runoff. SMR credit is the sum of three subelements:
1. Size of developments regulated (SZ): Up to 25 points.
2. Design storms used in regulations (DS): Up to 90 points.
3. Public maintenance of required facilities (PUB): Up to 110 points.
b. Watershed master plan (WMP): Up to 225 points are provided for regulating development according to a
watershed management master plan.
c. Freeboard for new buildings in B, C, D, and X zones (FRX): Up to 150 points are provided for requiring all
new buildings (not just those in floodplains) to be protected from local drainage problems.
d. Erosion and sedimentation control regulations (ESC): Up to 45 points are provided for regulations to
minimize erosion from land disturbed due to construction or farming.
e. Water quality regulations (WQ): 25 points are provided for regulations that improve the quality of stormwater
runoff.
452 Impact Adjustment. The credit points for SMR and WMP are adjusted in one of three ways. The
standards for the other elements must apply throughout the community, so there is no impact adjustment for
them.
a. Under Option 1, if the standards apply throughout all watersheds affecting the community, the impact
adjustment ratio for an element is 1.0.
b. Under Option 2, if the standards do not apply throughout all watersheds affecting the community, a default
impact adjustment ratio of 0.25 may be used.
c. Under Option 3, if the standards do not apply throughout all watersheds affecting the community, the impact
adjustment ratios may reflect the proportion of the watersheds affected.
453 Credit Calculation. The credit points for each element are multiplied by the impact adjustment ratios
and the products are totaled.
454 Credit Documentation. The community must submit the following:
a. [If requesting credit for SMR] A copy of the language from the ordinance or law that tells how surface water
runoff from new development is regulated.
b. [If requesting credit for WMP] Certification and appropriate pages from the watershed master plan.
c. [If requesting credit for FRX] A copy of the language from the ordinance or law that requires elevation of the
lowest floor or lowest opening of new buildings.
d. [If requesting credit for ESC] A copy of the erosion and sediment control ordinance or law.
e. [If requesting credit for WQ] A copy of the language from the ordinance or law that requires new
developments to implement appropriate best management practices.
f. [If impact adjustment ratios use Options 1 or 3] An Impact Adjustment Map showing the watershed
boundaries and stormwater management jurisdiction.
g. [If impact adjustment ratios include areas regulated by another community(ies)] Documentation of the other
community’s (or communities’) regulation.
h. [If requesting credit for PUB] A copy of inspection and maintenance procedures for drainage facilities.
The community must have the following available to verify implementation of this activity:
i. Development and building permit records that demonstrate enforcement of the regulations.
j. An evaluation report on the effectiveness and currency of the stormwater management plans.

450 STORMWATER MANAGEMENT
NOTE: A separate publication, CRS Credit for Stormwater Management, provides an
example of a community program and application documentation. Communities are
encouraged to obtain and read this document before applying for this activity. It will improve
the quality of the application and reduce the need to provide additional documentation later.
To order a free copy, see Appendix E.
Credit is provided for regulating new developments to minimize their impact on surface
water drainage and runoff.
Background: One of the greatest problems of floodplain management in urbanizing
areas is the increase in peak flow caused by watershed development. As forests,
fields, and farms are covered by impermeable surfaces, such as streets, rooftops, and
parking lots, more rain runs off at a faster rate. When an area is urbanized, the rate of
runoff can increase five-fold or more.
A great deal of damage from local drainage problems can be avoided by requiring all
structures to be elevated. Sediment from disturbed ground can reduce the capacity of
the drainage system and adversely affect water quality.
This problem is compounded by changes in the surface drainage system. Stormwater runoff
travels faster on streets and in storm drains than under pre-development conditions. As a
result, flooding is more frequent, happens more quickly, and is more severe.
Activity Description: This activity credits five approaches to regulating new
development in the watershed:
1. Regulating developments on a case-by-case basis to ensure that the peak flow of
stormwater runoff from each site will be no greater than the runoff from the site
before it was developed;
2. Regulating developments according to a watershed management master plan that
analyzes the combined effects of existing and expected development on drainage
through and out of the watershed;
3. Requiring all new buildings (not just those in the floodplain) to be elevated to protect
them from local drainage problems;
4. Regulating activities throughout the watershed to minimize erosion that results in
sedimentation; and
5. Regulating the quality of stormwater runoff.
CRS Coordinator’s Manual
450-2
Edition: July 2007
Stormwater Management
These five approaches are discussed in more detail below.
1. Because the amount of runoff is generally increased by development, stormwater
management usually requires that a volume of flood water be stored during the storm.
It is released after the runoff subsides (stormwater DETENTION). A developer may store
this excess runoff for a short time so that it may be used for irrigation or groundwater
recharge or to reduce pollution (stormwater RETENTION ). Where retention is used for
stormwater management, the detained runoff is not discharged until after the storm has
passed and the receiving body can carry the discharge without causing damaging peak
flows anywhere downstream.
Detention does not reduce the amount of water flowing downstream, it simply lets it
out over a longer period of time to reduce the peak flow. This can still cause flooding
problems farther downstream and the extra flows can destabilize channel banks and
cause other problems. Therefore, stormwater retention is preferred over detention. If
stormwater retention is allowed, the community must ensure that adequate storage is
again available within a reasonable time should another storm occur.
Maintenance of these facilities is vital—if they silt in or become clogged, they provide
no flood protection benefits.
2. Watershed master plans can be used to determine the appropriate amount of detention
or retention necessary to prevent an increase in runoff as development occurs within
the watershed. A master plan coordinates the timing and total volume of peak flows
from subwatersheds in order to provide better data for development standards.
Although there is no doubt that stormwater regulation reduces the future flood threat
from a developing area, a master plan goes much further in predicting the
rainfall/runoff relationships within the watershed and in locating and dealing with
specific problems as development progresses.
3. Much of the nation’s flood damage (including one-third of all flood insurance losses)
occurs in B, C, and X Zones. A large portion of this damage would be prevented by
requiring ALL new development to be elevated. This is usually done by requiring
lowest floors or basement openings to be elevated above street level.
4. Sediment control is especially important in watersheds where land is being disturbed
by construction or farming. Drainage systems cannot operate as designed if they are
choked with sediment washed in from construction sites. Sedimentation has also been
called the largest source of water pollution in the country.
5. Stormwater runoff picks up dirt, road oil, salt, farm chemicals, and other substances.
Unlike sewage, stormwater is not treated before it enters rivers, lakes, estuaries, and
other receiving bodies of water. Regulations that require developers to install or
implement measures that improve the quality of stormwater are credited.
CRS Coordinator’s Manual
450-3
Edition: July 2007
Stormwater Management
Unless care is taken to avoid it, each new development in a watershed increases the runoff
from the newly developed area, and flood peaks and flood volumes increase farther down the
watershed as development continues. Many communities and some states now require that the
runoff from new development be managed to reduce this increase in runoff. SMR credit is
provided for this regulation.
The term “stormwater management” is also widely used in programs intended to maintain or
improve the quality of stormwater runoff. Such water quality programs are provided CRS
credit under Section 451.e, below. These programs frequently regulate a relatively small level
of runoff, such as the first half-inch of runoff or the runoff from a 2-year storm.
Credit for stormwater management regulations (SMR) is provided for regulation of new
development to prevent future increases in flood damage that result from development in the
watershed. Therefore, SMR credit is only provided for regulation of runoff from a 10-year
storm or larger. More credit is provided for regulation of larger storms and maximum credit is
provided if runoff from both small and large storms is regulated.
Stormwater management regulation credited under Section 451.a (SMR) helps to manage
increased runoff from a developing watershed, but it does not solve the problem entirely. The
flood peak at a point downstream in a watershed is a result of both the quantity of upstream
runoff and the time it takes for water to travel down the watershed. Development within the
watershed usually has an impact on both of these characteristics.
The objective of watershed master planning under Section 451.b (WMP) is to provide the
community with a tool it can use to make decisions that will reduce the increased flooding
from development on a watershed-wide basis. Most communities have some way of dealing
with drainage problems, through a capital improvement plan, planned flood control
structures, or perhaps just by responding to complaints as they arise. A watershed master
plan, like other community plans, allows the community to consider future development as it
works on current problems.
For CRS credit, development of a watershed master plan does not imply that a community
must immediately address its future problems through capital drainage projects. It should be
considered a tool to help the community identify opportunities to address problems before
and as they arise.
The only way to completely understand how a watershed works, and how it will work as
development proceeds, is to do a relatively detailed study of runoff under both present and
future conditions. Doing the present-condition model allows the model to be calibrated to
current experience. The community already knows where its problem areas are, and the model
results should agree with this knowledge. Using information from future land use planning to
modify the model will show the locations and magnitude of future problems. This is generally
the first step in developing a watershed master plan. The present- and future-conditions
hydrology and hydraulics are usually done using the U.S. Army Corps of Engineers’ HEC-1
model or something similar.
CRS Coordinator’s Manual
450-4
Edition: July 2007
Stormwater Management
In addition to the present- and future-conditions hydrology studies, a watershed master plan
should include mitigation recommendations that are appropriate for the community. These
recommendations should include the entire range of mitigation activities—public information,
structural control of runoff, non-structural programs (usually including stormwater
management regulations), and acquisition of floodprone properties.
At a minimum for CRS credit, a watershed master plan must address the regulatory standards
for new development. The modeling might show that different standards are needed for
different watersheds, or for different parts of the watershed.
Other recommendations might be:
•
To initiate a public information campaign to encourage property owners to adjust their
landscaping to retain more runoff.
•
To decide that all future capital improvements on streets and drainage systems will use
the future-conditions hydrology. A 10% increase in the cost of a new culvert or bridge
might bring huge future reductions in flood damage.
•
To recommend a new revenue source to work on existing problems. Watershed-based
drainage districts with taxing authority are becoming common in many areas of the
country.
One of the prerequisites for CRS Class 4 (see Section 211.c) is that the community receive
credit for watershed master planning based on the 100-year storm. Most communities use
different storms for different design and management purposes. Development of a watershed
master plan does not have to change that.
For example, a community might require that the 5-year storm be contained in storm sewers,
the 10-year storm be contained in streets below the curb, the 25-year storm be at least 12
inches below the floors of new buildings, and the 100-year storm be below the floor
elevations. If the community uses future-conditions hydrology to develop 5-, 10-, 25- and
100-year storms in the plan, it can use the results to effectively reduce future flood damage
without revising the nominal requirements.
451 Credit Points
Maximum credit for Activity 450: 670 points.
a. Stormwater management regulations (SMR) (Maximum credit: 225 points)
SMR credit is provided if new developments are required to prevent or reduce the
increase in runoff that results from urbanization of the watershed. To receive SMR
credit, the watershed must be subject to a regulation that requires the peak runoff
from new developments to be no greater than the runoff from the site in its pre-
CRS Coordinator’s Manual

Stormwater Management
development condition. Credit may be provided for other approaches to managing
the impact of development on runoff where the community can show that there is no
increase in flood damage downstream.
SMR credit is the sum of the credit for three sub-elements:
SMR = SZ + DS + PUB.
If SZ = 0, then SMR = 0.
1. Size of development (SZ) (Maximum credit: 25 points)
SZ is based upon the minimum size of areas regulated. Use either:
(a) 25, if all development is regulated;
(b) 20, if all development is regulated except for single-family residences,
parcels of 1/2 acre or less, or increases in impervious area of 5,000
square feet or less;
(c) 15, if all development is regulated except for parcels of 1/2 acre or less or
increases in impervious area of 10,000 square feet or less; or
(d) 5, if all development is regulated except for parcels of 5 acres or less or
increases in impervious area of 20,000 square feet or less; or
(e) 0, if the regulations only affect development of parcels larger than 5 acres
or increases in impervious area of more than 20,000 square feet. If the
regulations only cover such large development projects, there is no credit
for SZ or SMR.
SZ provides different credit for different types of development. For example, if the
community regulates commercial developments that are larger than 1 acre (SZ = 15) and
residential developments larger than 5 acres (SZ = 5), an impact adjustment using Options 2
or 3 must be used to reflect the percentage of land use in each category. A similar adjustment
must be made if the regulations do not apply to government agency developments.
If developments are exempt from regulation for some reason other than size, the community
must relate this to one of the standards given. For example, the community could calculate
the average size of such exempted developments over the last several years. The ISO/CRS
Specialist should be contacted for assistance on this.
The CRS does not credit regulations that apply only to large developments (larger than 5
acres or more than 20,000 square feet of impervious surface) because the cumulative effect of
a number of small, unregulated developments could have just as significant an impact on
runoff in the watershed as a large development could.
CRS Coordinator’s Manual
450-6
Edition: July 2007
Stormwater Management
Credit may be provided for requiring developers to pay fees in lieu of constructing facilities,
if the fees collected go toward construction of the necessary facilities.
Example 451.a-1. As a condition of subdivision, planned unit development, or
other permit approval, Watertown requires that all developments larger than 1 acre
ensure that the post-development stormwater discharge will not exceed the amount
of runoff under pre-development conditions.
SZ = 5
2. Design storms (DS) (Maximum credit: 90 points)
DS is the total of the following points based on the design storms used in the
regulations (i.e., the storms used to measure the impact of new developments).
For DS credit, the community’s regulations must require pre- and postdevelopment hydrology calculations and post-development runoff must be
limited to pre-development levels. The standard used may be peak flow, volume,
or a combination of the two.
(a) 60, if detention/retention is designed for the 100-year storm;
(b) 20, if detention/retention is designed for a storm larger than the 10-year but
smaller than the 100-year storm; and
(c) 10, if detention/retention is designed for a 10-year storm.
Although the 100-year flood is the basis for floodplain management, many communities use a
lesser standard for stormwater management. A lower standard may meet many community
needs, but management of smaller storms does not necessarily result in reduced peak flows or
volume from a major storm.
The community must require management of at least a 10-year storm. A regulation designed
to retain or detain only the “first flush,” the first inch of rainfall, or less than a 10-year storm,
is not credited under SMR. However, it may qualify as a water quality regulation (WQ) and
be credited under Section 451.e.
DS credit of 90 points is provided if the regulation clearly states that all discharges UP TO AND
INCLUDING the 100-year storm discharge must be released at rates not exceeding the predevelopment peak discharge.
CRS Coordinator’s Manual
450-7
Edition: July 2007
Stormwater Management
Example 451.a-2. Watertown’s stormwater management ordinance used to
require regulation of the 2- and 10-year storms to prevent increases in runoff. Under
that ordinance, DS = 10. Similarly, if the ordinance had been based on the 25- and
50-year storms, DS would be 20.
Watertown’s current ordinance requires determination of a proposed development’s
effects on the 10- and the 100-year storms to ensure that downstream peak flows
are not increased.
DS = 10 + 60 = 70
Example 451.a-3. Gulf Beach County requires all new developments to retain
the runoff from all storms up to and including the 100-year storm.
DS = 10 + 20 + 60 = 90
3. Public maintenance (PUB) (Maximum credit: 110 points)
Credit for PUB is provided if the community assumes maintenance responsibility
for all new stormwater facilities or if the community inspects all new stormwater
facilities at least annually and has regulatory authority to require the owners to
perform appropriate maintenance.
PUB = 110, for public maintenance of all stormwater facilities.
Because experience has shown that private maintenance of stormwater management facilities
is not as reliable in the long term, credit is provided to encourage maintenance by a public
agency, or inspections by a public agency and maintenance as indicated by the inspections.
A community can receive PUB credit through any one or combination of three ways:
1. At least once each year, the community (or other stormwater management agency)
inspects all stormwater management facilities constructed after the date of adoption of
the regulation and orders maintenance when needed. If the owner fails to perform the
maintenance, the community (or agency) does the job and bills the owner;
2. At least once each year, the owners of all stormwater management facilities
constructed after the date of adoption of the regulation have the facilities inspected by
a licensed professional engineer and perform the maintenance recommended by the
CRS Coordinator’s Manual
450-8
Edition: July 2007
Stormwater Management
engineer. The owners must provide the engineer’s inspection reports and
documentation of the maintenance performed at least annually; or
3. All stormwater management facilities constructed after the date of adoption of the
regulation (including basins built by private developers) are required to be deeded to
the community (or other stormwater management agency), and the community (or
agency) inspects the facilities at least annually and provides maintenance as needed.
Whichever approach is used, it must be supported by an ordinance or other regulatory
authority. For example, holding the owner responsible for maintenance must be based on
clear legal authority, such as the subdivision ordinance, that was known to the developer at
the time of construction of the stormwater facility. Credit is not provided for a policy or a
statement that the community has been able to get compliance in the past.
If inspection is performed by the community, the community must document its inspection
program with all documentation required for channel debris removal (CDR) in Section 544.
Example 451.a-4. Watertown maintains all detention facilities in all developments:
PUB = 110
Watertown’s other values were calculated above: SZ = 5 and DS = 70.
SMR = SZ + DS + PUB = 5 + 70 + 110 = 185
b. Watershed master plan (WMP) (Maximum credit: 225 points)
1. Prerequisites:
(a) The community must have adopted a watershed master plan for one or more
of the watersheds that drain into the community.
(b) The community has adopted regulatory standards for new construction in the
watershed based on the plan.
(c) The plan’s regulatory standards manage future peak flows so that they do
not increase over present values.
(d) The plan’s regulatory standards require management of runoff from all
storms up to and including the 25-year event.
CRS Coordinator’s Manual
450-9
Edition: July 2007
Stormwater Management
(e) In order to maintain WMP credit for any plan that is more than five years old,
the community must evaluate the plan to ensure that it remains applicable to
current conditions. The evaluation must address whether the dates used for
the plan are still appropriate and whether the plan effectively manages
stormwater runoff. If a watershed master plan is obsolete, the community
must update the plan or the WMP credit will be revised accordingly.
2. WMP = the total of the following points. Credit must be received for item (a).
(a) 80, if the watershed master plan meets all of the prerequisites listed in
Section 451.b.1.
(b) 25, if the plan manages the runoff from all storms up to and including the
100-year event.
(c) 40, if the plan provides management of future peak flows AND VOLUMES so
that they do not increase over present values. If the community can
demonstrate that its watershed plan prevents damaging increases in
peak flows at all points within its watershed(s) and downstream, it will
receive this credit.
(d) 25, if the plan manages the runoff from all storms up to and including the 5day event. If a community can demonstrate that an event shorter than
five days is the locally appropriate “worst-case” runoff event for
stormwater management, it may receive the credit if it uses that event for
its regulatory standard.
(e) 15, if the plan identifies existing wetlands or other natural open space areas
to be preserved from development to provide natural attenuation,
retention, or detention of runoff.
(f) 10, if the plan prohibits development, alteration, or modification of existing
natural channels.
(g) 10, if the plan requires that channel improvement projects use natural or
“soft” approaches rather than gabions, rip rap, concrete, or other “hard”
techniques.
(h) 20, if the plan was prepared in coordination with or as a part of the
community's floodplain management plan credited under Activity 510.
Credit is provided if the community develops and implements surface water runoff
regulations through a watershed master plan that ensures that flood damage within and
downstream from the watershed is not increased by future development. Eighty points are
provided for the plan, provided that its standards:
•
Have been adopted in the community’s regulatory program,
•
Require that the peak flows of runoff from future development will not increase
beyond the present peak flows, and
CRS Coordinator’s Manual
450-10
Edition: July 2007
Stormwater Management
•
Manage all storms up to and including the 25-year storm (no credit is provided for
WMP for management of storms smaller than the 25-year storm).
Communities that receive 80 points for the watershed master plan can then receive additional
points under subsections (b) through (h).
(b) Twenty-five points are added if the community’s regulations manage all storms up to and
including the 100-year storm. “All storms” includes specifically listed storms, such as the
2-, 10-, 25-, 50-, and 100-year storms.
(c) Forty points are added if the plan’s regulatory standards prevent all increases in
downstream flood peaks AND VOLUMES, regardless of the size of the watershed or its
location within a larger basin. A community can receive the maximum credit if it detains
runoff from a 25-year or larger storm and discharges it to groundwater or irrigation or if it
detains the runoff long enough to discharge it after the peak flow in the receiving body
has subsided so the discharge will not increase downstream peak flows anywhere in the
receiving stream.
Communities that discharge directly into an ocean or a Great Lake may receive this credit
if they have adopted a watershed master plan that models their watershed(s) and prevents
increased peak flows within those watershed(s). Communities with watersheds that
discharge into other large lakes or rivers must demonstrate that their discharges will not
increase flood elevations in the lake or anywhere downstream on the receiving river.
(d) Twenty-five additional points are provided for assuring that the most appropriate
modeling techniques are used for the location. This is assumed to be a 5-day event unless
the community can show that a shorter event is more appropriate for local conditions. In
some areas this may require continuous-simulation modeling. If a community, regional,
state, or federal agency can demonstrate that, say, the 72-hour event provides the “worst
case” runoff for a watershed, the 72-hour event would be credited for communities in that
area.
(e)—(g) These additional points recognize communities that preserve their remaining
“natural” channels, floodplains, or upland wetlands for stormwater conveyance or
storage. “Soft” or “green” approaches are encouraged over “hard” or concrete
measures.
(h) The last 20 possible additional points are dependent on the community’s receiving credit
for a floodplain management plan under Activity 510. A floodplain management plan
developed for Activity 510 (Floodplain Management Planning) probably will not qualify
for WMP credit, but a watershed master plan may qualify for credit under Activity 510. A
community may be eligible for these 20 points if:
•
The Floodplain Management Plan is mentioned prominently in the watershed
master plan, and if references in the watershed master plan demonstrate that it is
intended to help implement the Floodplain Management Plan; and/or
CRS Coordinator’s Manual
450-11
Edition: July 2007
Stormwater Management
•
Hydrologic output from the watershed master plan is used as input for the
Floodplain Management Plan.
c. Freeboard for new buildings in B, C, D, and X Zones (FRX) (Maximum credit: 150
points)
FRX is determined by the type and amount of freeboard required in B, C, D, or X
Zones (FX). FRX credit is not provided for a freeboard requirement above the base
flood elevation. FRX credit is not provided to communities that are entirely Special
Flood Hazard Area (SFHA). FRX = one of the following:
1. 50 x FX (the height in feet that the lowest floor (including basement) must be
above the crown of the nearest street or the highest grade adjacent to the
building); or
2. 25 x FX (the height in feet that the lowest opening or point of entry must be
above the crown of the nearest street or the highest grade adjacent to the
building); or
3. 50, if the regulations require that as a condition for a building permit, the
applicant must prepare a site plan that accounts for local drainage from
and onto adjoining properties and that protects the building from local
drainage flows; or
4. 20, if the regulations require that the applicant provide positive drainage away
from the building site.
FX is reduced by 0.5 feet if the standard is an elevation above the gutter rather than
the crown of the street.
The FRX regulatory language is usually found in the building code, rather than in the
ordinance with the floodplain or stormwater management regulations. Several of the national
model codes require site plans or positive drainage.
Under items c.1. and 2., the maximum credit is provided for 3 feet of freeboard. The highest
adjacent grade or other datum may be used as an alternative to the crown of the nearest street.
If the street gutter is used, 0.5 feet is subtracted from the amount of freeboard.
There is no impact adjustment for FRX because it must be enforced throughout either the
entire community or the B, C, D, and X Zones.
A community may request credit for FRX even if it does not apply for credit for the other
elements of this activity.
CRS Coordinator’s Manual
450-12
Edition: July 2007
Stormwater Management
Example 451.c -1. Watertown has adopted a version of the Uniform Building
Code that requires the lowest floor to be at least 14" above the crown of the adjacent
street.
FRX = 50 x FX = 50 x 14" = 50 x 1.17 = 58.5
12"
d. Erosion and sedimentation control regulations (ESC) (Maximum credit: 45 points)
ESC is based upon the areas regulated. ESC = one of the following:
1. 45,
if regulations control erosion and soil loss from any disturbed land,
including agricultural lands, greater than 1,000 square feet;
2. 35,
if regulations control erosion and soil loss from construction sites as small
as 1/2 acre;
3. 30,
if regulations control erosion and soil loss from construction sites as small
as 1 acre; or
4. 15,
if regulations control erosion and soil loss only from construction sites
greater than 5 acres.
This credit is provided because drainage systems cannot perform to their design standards if
they are choked with sediment, a particular problem when the ground has been disturbed by
development. This credit is for regulations that are applied throughout a community, not just
in floodprone areas.
“All construction sites” in subsections d.2, 3, and 4 means all sites subject to construction of
buildings, roads, etc., regrading, or other non-agricultural land-disturbing activity. An erosion
and sedimentation control regulation that is part of a floodplain ordinance or a building code
and does not affect ALL construction sites in the community does not receive full credit under
this element.
A community may have regulations that exempt agricultural uses from erosion and sediment
control requirements. For example, the state enabling legislation may not allow regulation of
farms. In such cases, the community may apply for ESC = 45 if it can document that there are
no agricultural zones and no existing agricultural uses within its corporate limits and all other
projects (except those smaller than 1,000 square feet) are regulated.
CRS Coordinator’s Manual
450-13
Edition: July 2007
Stormwater Management
Example 451.d-1. Appropriate ordinance language might read:
Prior to any grading or other earthwork that affects a land area larger than 500
square feet, the person performing such earthwork shall submit an erosion control
plan. The plan shall be designed to prevent sediment from leaving the site during
storms up to and including the 100-year storm and recover the ground after
construction or other work to prevent or minimize erosion. [ESC = 45]
or
Application for any grading and/or building permit (except for single-family dwellings
on existing platted lots) must include an erosion control plan designed to prevent
sediment from leaving the site during the 100-year storm and recover the ground
after construction to prevent or minimize erosion. [ESC = 35]
e. Water quality regulations (WQ) (Maximum credit: 25 points)
WQ = 25, if regulations require new developments of 5 acres or more to include in
the design of their stormwater management facilities appropriate "best management
practices" that will improve the quality of surface water.
Most states’ environmental protection or pollution control offices have recommended best
management practices (BMPs) appropriate for that state. Best management practices may
include grass filter strips at retention basin inlets or outlets, velocity dissipators and baffles,
basin dimensions that encourage settling of suspended solids, aeration, infiltration trenches,
skimmers, vegetated swales, and other techniques that clean stormwater. It should be noted
that this credit is not for BMPs required during the course of construction, but rather for
measures that are permanently incorporated in the development’s stormwater management
facilities.
For WQ credit, the stormwater management regulations must either specify one or more
measures or refer to best management practices as published in an official government reference. A mention of water quality or reduction of nonpoint sources of pollution in the purpose
section of the regulations is not sufficient for credit.
Example 451.e-1. Watertown is located in a state-designated estuarine
protection area. The plans for all new developments larger than 1 acre must be sent
to the state coastal zone management agency for approval. The state regulations
stipulate best management practices to improve the quality of the stormwater
entering the estuary.
WQ = 25
CRS Coordinator’s Manual
450-14
Edition: July 2007
Stormwater Management
452 Impact Adjustment
There are no impact adjustment ratios for FRX, ESC, or WQ because they must be
enforced throughout the community. Credit for FRX is provided if the regulation applies
only to areas outside the regulatory floodplain.
a. Option 1:
1. Stormwater management regulation (SMR): If the community, separately or
along with upstream communities, regulates development within all of the
watersheds that affect it, rSMR = 1.0.
2. Watershed master plan (WMP): If the watershed master plan regulates all
development within all of the watersheds that affect the community, rWMP = 1.0.
A community may choose to exclude watersheds larger than 50 square miles. If such large
watersheds are outside the community’s jurisdiction, or are not regulated, the community will
receive more credit by excluding them. If they are regulated, the community will receive
more credit by including them.
The two “r” variables are used to reflect the ratio of the area covered by the community’s
basic regulations and the area covered by the community’s watershed management plan.
aWMP must be included in aSMR. If all regulated areas are included in the watershed plan,
rWMP = 1.0.
Few communities will be able to use Option 1 to determine their impact adjustments because
few communities have regulatory jurisdiction over areas that coincide with their watershed
boundaries. The only cases that have arisen so far are:
•
Communities that are islands,
•
Communities subject to state or regional stormwater regulations that affect their entire
watersheds, and
•
Communities, usually counties, whose corporate boundaries are formed entirely by
watershed divides (ridges), or bodies of water.
b. Option 2:
1. Stormwater management regulation (SMR): If the community does not regulate
development within all of the watersheds that affect it, it may use the default
value rSMR = 0.25.
CRS Coordinator’s Manual
450-15
Edition: July 2007
Stormwater Management
2. Watershed master plan (WMP): If the watershed master plan does not regulate
all development within all of the watersheds that affect the community, it may
use the default value rWMP = 0.25.
Many communities find it difficult to determine the size of the watersheds. Therefore, 25% of
the credit is given for cSMR if no rSMR is calculated. A community that regulates less than
25% of its watersheds may also use Option 2 to determine the minimum value of rSMR.
Example 452.b-1. Watertown regulates all watersheds within its corporate
limits. However, areas outside the corporate limits are not regulated. Watertown uses
Option 2: rSMR = 0.25.
c. Option 3:
1. Stormwater management regulation (SMR): If the community does not regulate
development within all of the watersheds that affect it, it may develop a
Stormwater Impact Adjustment Map to determine the areas required to calculate
rSMR:
rSMR = aSMR, where
aW
aSMR = the area of stormwater management regulation, and
aW = the area of all watersheds affecting the community.
2. Watershed master plan (WMP): If the watershed master plan does not include
all areas of stormwater management regulation within the community, it may use
the Stormwater Impact Adjustment Map to determine the areas required to
calculate rWMP:
rWMP = aWMP, where
aW
aWMP = the area covered by a watershed master plan.
If a community can demonstrate that the upstream portion of its watershed is
managed to a similar standard, either by other communities separately or by a
regional entity like a drainage or flood control district, aSMR and aWMP may be
CRS Coordinator’s Manual
450-16
Edition: July 2007
Stormwater Management
increased. The community must document such management in accordance with
Section 454.
If a community can demonstrate that the upstream portion of its watershed is managed to a
similar standard, either by other communities separately or by a regional entity like a
drainage or flood control district, aSMR and aWMP may be increased. The community must
document such management in accordance with Section 454.
Because this activity only affects watersheds under the jurisdiction of stormwater
management regulations, impact adjustment ratios must be determined for stormwater
management regulation and the watershed master plan.
In order to use Option 3 and determine aSMR, aW, and aWMP, the community must prepare a
Stormwater Impact Adjustment Map. Although the purpose of this map is similar to the
Impact Adjustment Map discussed in Section 403, it may be quite different in appearance.
The base map for the Stormwater Impact Adjustment Map should be a small-scale map that
can show all of the watersheds affecting the community. A community may choose to exclude
watersheds larger than 50 square miles. If such large watersheds are outside the community’s
jurisdiction, or are not regulated, the community will receive more credit by excluding them.
If they are regulated, the community will receive more credit by including them.
The entire watershed for each watercourse draining into or through the community should be
shown on this map (except those with drainage areas over 50 square miles, if they are
excluded from the calculations). The total area of these watersheds is aW. With appropriate
documentation, aW may be reduced in two ways:
1. If upstream watersheds are effectively reduced by flood control structures that control
the base flood, the size of aW is reduced accordingly.
NOTE: Only structures designed to control the base flood can be used for this type of
adjustment to aW.
2. If portions of the watersheds are unlikely, because of their ownership, to be
developed, those portions may be excluded from aW. Areas that might be excluded are
national forests, state parks, or privately owned land dedicated to open space use.
Communities are encouraged to cooperate with adjacent communities to manage stormwater.
If a community only has regulatory jurisdiction over a portion of its watersheds, it cannot
ensure that properties will be safe from increased runoff in the future. However, if upstream
communities also manage future development, either independently or through county-wide
or watershed planning, all communities can benefit. Therefore, if a community can
demonstrate that upstream communities have similar watershed management programs for the
upper portions of their watersheds, it can include those areas in aSMR and aWMP.
CRS Coordinator’s Manual

Edition: July 2007
Stormwater Management
Communities are encouraged to check with their state or regional stormwater management
agency to see if they can apply for “uniform minimum credit,” i.e., credit based on the
stormwater management program implemented by the regional agency.
453 Credit Calculation
a. cSMR = SMR x rSMR
b. cWMP = WMP x rWMP
c. c450 = cSMR + cWMP + FRX + ESC + WQ
Example 453-1. Watertown's credit points are discussed above:
SMR = 185, rSMR = 0.25, cSMR = 185 x 0.25 = 46.25
FRX = 58.5
WQ = 25
c450 = 46.25 + 0 + 58.5 + 25 = 129.75, which is rounded to 130
During the field verification, the ISO/CRS Specialist examined a selection of public
and privately owned facilities and they appeared to be properly maintained.
454 Credit Documentation
The community must submit the following:
a. [Required if the community is applying for credit for SMR under Section 451.a]: A
copy of the ordinance or law language regulating surface water runoff from new
developments in the watershed. For SMR credit, the language must require that
peak runoff from new developments be no greater than the runoff from the site in its
pre-development condition. The margin next to where this appears in the ordinance
must be marked “SMR.”
The language submitted must include those factors that are credited: size of
developments regulated, design storms to be used, and how the maintenance of
drainage and retention facilities is handled. The appropriate acronym(s) (SZ, DS,
and PUB) must be marked in the margin of the ordinance sections that pertain to
each element.
CRS Coordinator’s Manual
450-18
Edition: July 2007
Stormwater Management
The community may also be asked to complete an activity worksheet that helps
identify where the credits are due.
As an alternative to such a performance standard, the language may be based on criteria
designed to produce the same result on a regional basis (e.g., a standard allowable discharge
per acre based on a regional study). If such language is used, the community must provide an
estimate of the design storm controlled and a comparison of the pre-development runoff and
the permitted discharge.
For CRS credit, the regulations must be legally enforceable. Policies and guidelines are not
acceptable unless the community’s legal counsel states that they are enforceable.
A photocopy of the appropriate pages of the ordinance(s) (e.g., subdivision and/or zoning
ordinances) or statute, including the cover page to identify the document, is sufficient and
should be attached to the activity worksheets. The Chief Executive Officer’s (CEO’s) certification is considered to include a certification that the ordinance or statute has been enacted
into law and is being enforced (see Section 212.a).
Example 454.a-1. Sample ordinance language might read:
All new development within the Little River watershed shall be designed to prevent
any increase in peak flow, velocity, or total runoff volume during the 5-year and 100year rainfall events. Prior to development, the developer must submit hydrologic and
hydraulic studies showing the nature and extent of runoff under present conditions
and with the proposed development for those two rainfall events.
b. [Required if the community is applying for WMP credit under Section 451.b] Copies
of the pages of the watershed master plan that show the following:
1. Management of peak flows and volumes so that they do not exceed present
values. The plan must include either regulations that meet these criteria, or must
be based on a rainfall/runoff model that achieves these results;
2. The recurrence interval of the storm used for the regulations and/or model;
3. The duration of the storm used for the regulations and/or model;
4. [Required if the community is applying for credit for Section 451.b.2(e)—(g)]
How the plan utilizes or protects the existing natural stormwater features within
the watershed; and
CRS Coordinator’s Manual
450-19
Edition: July 2007
Stormwater Management
5. [Required if the community is applying for credit for Section 451.b.2(h)] A
statement by the community official responsible for implementation of the
watershed master plan that it was prepared in coordination with or as part of the
community’s Floodplain Management Plan credited under Activity 510. This
documentation may be provided from either plan if it is contained there.
The community may also be asked to complete an activity worksheet that helps
identify where the credits are due.
A watershed management plan is usually a complex, bulky document. It may have an introduction or summary describing the area covered by the plan, its objectives, and the regulation
of surface water runoff. This summary is probably adequate documentation for some or all of
this credit. If no such summary is available, it must be developed to document this credit.
There are three ways for the community to document its credit for WMP:
● Mark the appropriate sections of the plan with the section numbers in Section
451.b (451.b.1(b), 452.b.2(c), etc.);
● Write a memo listing the credits requested and giving the pages and sections
where the language can be found; or
● Complete the activity worksheet that identifies where the credits are found.
c. [Required if the community is applying for FRX credit under Section 451.c] A copy of
the ordinance or law language that requires elevation of the lowest floor or lowest
opening of new buildings. The acronym FRX must be marked in the margin of the
section that pertains to this element.
This documentation may be in the community’s building code. If the community has adopted
one of the national model building codes, documentation of that adoption, as well as the code
language, must be provided.
d. [Required if the community is applying for ESC credit under Section 451.d] The
ordinance or law language that requires developers or property owners to use
techniques that prevent erosion and soil loss from exposed land. The ordinance(s) or
law must designate an office or official responsible for receiving complaints and
monitoring compliance and it must include enforcement and abatement provisions.
The acronym ESC must be marked in the margin of the ordinance section that
pertains to this element.

e. [Required if the community is applying for WQ credit under Section 451.e] The
ordinance or law language that requires new developments to implement
appropriate best management practices to improve water quality.
The acronym WQ must be marked in the margin of the ordinance section that
pertains to this element.
A copy of the appropriate pages of the ordinance or statute is sufficient. The CEO’s certification is considered to include a certification that the ordinance or statute has been enacted into
law and is being enforced (see Section 212.a).
f. [Required if the community calculates the impact adjustment ratio for one or more
elements by using Option 1 (Section 452.a) or Option 3 (Section 452.c)] An Impact
Adjustment Map showing watershed boundaries and stormwater management
jurisdiction.
The Impact Adjustment Map is explained in the Commentary text following Section 452.c. If
either Option 1 or 3 is used, the map is needed to verify the impact adjustment calculations.
g. [Required if the community determines the area of stormwater management
regulation (aSMR) or the area covered by the watershed master plan (aWMP) to
include watershed areas regulated by other communities] Documentation that
watersheds outside the jurisdiction of the community are regulated to similar
standards or are subject to the same plan as those within the community.
The applicant can provide the actual ordinance language from the community(ies) or written
assurance from a county, regional, or state agency that similar standards are in effect in the
upstream communities.
h. [Required if the community is applying for PUB credit under Section 451.a.3] The
procedures used to inspect and maintain drainage facilities.
The inspection and maintenance procedures for this activity must include the same five items
needed for Activity 540’s drainage system maintenance as specified in Section 544.a. It is
recommended that the stormwater management facility maintenance procedures be part of the
drainage system maintenance program because Activities 450 and 540 are closely related.

The community must have the following documentation available to verify
implementation of this activity:
i. Development and building permit records that demonstrate enforcement of the
regulations. If the community applied for credit for public maintenance under Section
451.a.3, records that demonstrate implementation of the inspection and
maintenance requirements.
If it has received credit for a watershed master plan (WMP) under Section 451.b, the
community must provide the following documentation at the time of its cycle
verification:
j. An evaluation report that addresses whether the community’s watershed master
plans that are more than five years old are still based on appropriate data and
effectively manage stormwater runoff. In lieu of a formal report, the community may
submit a letter signed by a licensed professional engineer that addresses the
following issues:
(1) The “future conditions” at the time the plan was completed: Do these conditions
still reasonably reflect the actual watershed conditions today?
(2) The precipitation data used for the plan’s hydrology: Does the community or
agency still use the same precipitation that was used in the report?
(3) Method used for the plan(s): Is the method used to develop the plan(s)
considered appropriate today by the agency?
(4) Construction: Has construction of stormwater infrastructure altered actual
conditions in ways that make the plan(s) obsolete?
(5) Other factors: Are there other aspects of the plan(s) that make it obsolete or
otherwise of questionable applicability?

Impact Adjustment.
Under Option 1, if the floodplain management plan covers all of the community’s known flood
hazard areas, the impact adjustment ratio is 1.0. If the repetitive loss area analyses cover all repetitive
loss areas, the impact adjustment ratio is 1.0 A Category C repetitive loss community must use
Option 1 if it is preparing a plan or analysis to meet the CRS participation prerequisite specified in
Section 502.
Under Option 2, if the floodplain management plan or repetitive loss area analyses cover some of the
community’s hazard areas, the impact adjustment ratio is 0.25. A Category C repetitive loss
community must use Option 1.
Under Option 3, the impact adjustment ratios reflect the proportion of the community’s repetitive loss
areas that are covered by area analyses.
Credit Calculation. The credit points for each element are multiplied by the impact adjustment
ratios and the products are totaled.

CRS Coordinator’s Manual
510-1
Edition: July 2007
Floodplain Management Planning
510 FLOODPLAIN MANAGEMENT PLANNING
Background: Programs that are based on a comprehensive floodplain management
or hazard mitigation plan address all the community’s flood problems more effectively.
NOTE: A separate publication, Example Plans, has a detailed discussion of the requirements
of this section and of multi-hazard mitigation plans, as well as model plans and application
documentation. Communities are encouraged to obtain and read this document before
applying for this activity. It will improve the quality of the submittal and reduce the need to
provide additional documentation later. To order a free copy, see Appendix E.
The objective of floodplain management or hazard mitigation planning is to produce a
program of activities that will best tackle the community’s vulnerability to the hazard(s) and
meet other community needs. A well-prepared plan will:
•
Ensure that a comprehensive review of possible activities and mitigation measures is
conducted so that the most appropriate solutions are used to address the hazard.
•
Ensure that the recommended activities meet the goals and objectives of the
community, do not create conflicts with other activities, and are coordinated to reduce
the costs of implementing individual activities.
•
Educate residents about the hazards, loss reduction measures, and the natural and
beneficial functions of floodplains.
•
Build public and political support for projects that prevent new problems, reduce
losses, and protect the natural and beneficial functions of floodplains.
•
Build a constituency that wants to see the plan’s recommendations implemented.
Activity Description: Credit is provided for preparing, adopting, implementing,
evaluating, and updating a comprehensive floodplain management plan. The
Department of Homeland Security’s Federal Emergency Management Agency (FEMA)
also requires a multi-hazard mitigation plan as a prerequisite for mitigation funding. The
CRS and FEMA do not specify what activities a plan must recommend, but they only
recognize plans that have been prepared according to the standard planning process
explained in FEMA regulations and Section 511 of this activity.
An area analysis focuses on reducing damage to repetitively flooded buildings. It has a
narrower scope than a plan, and receives fewer credit points. A Category C repetitive
loss community must prepare either a floodplain management plan or area analyses
that cover at least all of its repetitive loss areas. A community can receive credit for
both efforts, but they must be published as separate documents.
CRS Coordinator’s Manual
510-2
Edition: July 2007
Floodplain Management Planning
Action: Report recommended ordinance language to the City Council by March
2006.
Budget: staff time (operating funds).
4. The City Engineer will draft a comprehensive stormwater management plan for
the ditch draining the southeast part of town to identify the best locations for
stormwater facilities and set retention standards for new developments.
Action: Complete the first draft by September 2006.
Budget: staff time (operating funds).
5. The City Engineer will prepare a cost estimate for enlarging the culvert under the
railroad tracks to accommodate the base flood. The estimate will include a study
of the impact of increased flows on downstream properties, channel banks, and
habitat.
Action: Complete the study by January 2006.
Budget: staff time (operating funds).
Phase IV − Plan Maintenance
9. Adopt the plan (Maximum credit: 2 points) The 2 credit points for this step are
provided if the plan and later amendments are officially adopted by the
community’s governing body. (REQUIRED)
When a multi-jurisdictional plan is prepared, it must be adopted by the governing
board of each community seeking CRS or multi-hazard mitigation plan credit.
The plan must be an official plan of the community, not an internal staff proposal. Regional
plans are not adequate unless they specifically address the community’s natural hazards and
the community’s governing body adopted the plan.
Phase IV − Plan Maintenance
10. Implement, evaluate, and revise (Maximum credit: 15 points) The credit for this
step is the total of the following points based on how the community monitors
and evaluates its plan.
(a) 2, if the community has procedures for monitoring implementation,
reviewing progress, and recommending revisions to the plan in an
annual evaluation report. The report must be submitted to the governing
body, released to the media and made available to the public. (REQUIRED)
CRS Coordinator’s Manual
510-21
Edition: July 2007
Floodplain Management Planning
(b) 13, if the evaluation report that is credited in step 2(a) is prepared by the
same planning committee that prepared the plan or by a successor
committee with a similar membership that was created to replace the
planning committee and charged with monitoring and evaluating
implementation of the plan.
To maintain this credit, the community must submit a copy of its annual
evaluation report with its recertification each year and update the plan at least
every five years.
To be useful, planning must be dynamic. The plan should not sit on a shelf gathering dust
once it is completed. Therefore, the community must have an evaluation and update process.
No plan is perfect. As implementation proceeds, flaws will be discovered and changes will be
needed. Not only can hazard conditions change but also goals and objectives may change. If a
community is hit by a tornado, the planning may be changed to focus attention on the newly
damaged areas in the SFHA. Many communities have periodic meetings of the planning
committee to review progress to date and recommend changes to the projects for the next
year.
The plan must describe the how, when, and by whom the plan will be monitored. Monitoring
may include periodic reports by agencies involved in implementing projects or activities, site
visits, phone calls, and meetings conducted by the person responsible for overseeing the plan.
The plan must also include a description of how, when, and by whom the plan will be
evaluated, and should include the criteria used to evaluate the plan.
Those involved in developing and implementing the plan should meet periodically to review
progress toward the objectives and identify changes or revisions that should be made. This is
usually done monthly or quarterly, but must be done at least annually to facilitate preparation
of the annual evaluation report.
FAILURE
TO SUBMIT THE EVALUATION REPORT WITH THE ANNUAL RECERTIFICATION WILL
RESULT IN LOSS OF THE PLANNING CREDIT ( I . E ., FMP = 0). L OSS OF CREDIT FOR THIS ACTIVITY
WILL CAUSE A REPETITIVE LOSS C ATEGORY C COMMUNITY TO REVERT TO A C LASS 10.
Changes should be made in the action plan when opportunities arise to add new activities or
complete some items ahead of schedule. The plan should also be revised if it is found that
some activities cannot be completed on the original timetable. The revisions must be adopted
by the governing body as required under step 9.
b. Repetitive loss area analysis (RLAA)
Up to 50 points are provided for conducting area analyses of all of the community’s
repetitive loss areas. An area analysis is prepared according to the following criteria:
CRS Coordinator’s Manual
510-22
Edition: July 2007
Floodplain Management Planning
514 Credit Documentation
If the community already has a floodplain management, hazard mitigation, or similar plan
that meets the 10-step credit criteria, it need not prepare a new plan just for this CRS credit.
The community must submit the following:
a. The activity worksheet or plan review crosswalk that identifies the page or section
number where each credited item is located in the floodplain management or hazard
mitigation plan.
b. A copy of the floodplain management or hazard mitigation plan. At the time of cycle
verification, this section applies to the five-year update to the previously credited
plan. A description of the process used to develop (or update) the plan must be
included, either as part of the plan or attached to it. While some of the steps can be
explained in a separate memo, the following must appear in the plan document:
Step 1.
a description of the plan preparation process,
Step 4.
the hazard assessment,
Step 5.
the problem assessment,
Step 6.
goals of the floodplain management or hazard mitigation program,
Step 7.
the review of possible activities,
Step 8.
the action plan, and
Step 10. how the plan will be periodically evaluated and revised.
c. Documentation showing how the public was involved in preparing or reviewing the
plan, including a list of the members of the planning committee and their affiliations
and a copy of the notice(s) advising residents about the public meeting(s) held
pursuant to step 2(b) and (c), and a record of the meeting(s).
d. Copies of correspondence, meeting notes, or other materials that document the
coordination with other municipalities, agencies, and organizations credited under
Sections 511.a3(b)—(f).
The notice of the public input meeting(s) should be in the form of letters to floodplain
residents, a notice sent to all residents, or a newspaper article or advertisement. An
inconspicuous legal notice in the classified section of the newspaper will not be sufficient for
CRS credit. If very few residents are affected, as may be the case for planning that addresses
CRS Coordinator’s Manual
510-29
Edition: July 2007
Floodplain Management Planning
only a repetitive loss area, a written record that the residents were called would be sufficient
documentation.
A record of the meeting is also needed. This could be the minutes of the public meeting, a
memo for the record, or a list of the issues raised by those who attended.
e. Documentation showing that the floodplain management plan (or the five-year
update) and/or the Habitat Conservation Plan have been adopted by the community’s governing body. When a multi-jurisdictional plan is prepared, it must be
adopted by the governing board of each community seeking CRS credit. If the
community is applying for credit for a Habitat Conservation Plan that has been
accepted by the U.S. Fish and Wildlife Service or the National Marine Fisheries
Service, the documentation must include a written record of that acceptance.
Normally a plan is adopted by a formal resolution of the city council, county board,
or other governing body. A copy of the resolution or a copy of the minutes for the
meeting are appropriate documentation to show that the plan was officially adopted.
f. A copy of each repetitive loss area analysis to be credited and a memo or other
documentation showing that the head of the appropriate department has approved
it. The National Flood Mitigation Data Collection Tool database file must also be
provided, if requested.
The community must submit the following documentation with its annual CRS
recertification (see Section 214):
g. An annual report on evaluating progress toward implementing the action plan’s
objectives and/or the recommendations of the area analyses. A single report may
be prepared for all area analyses. The evaluation report must be submitted to the
governing body, released to the media, made available to the public, and included
as part of the community’s annual recertification. The report must include the
following:
1. A description of how the evaluation report was prepared and how it is submitted
to the governing body, released to the media, and made available to the public.
2. How the reader can obtain a copy of the original plan or area analysis report;
3. A review of each recommendation or action item in the action plan or area
analysis report, including a statement on how much was accomplished during
the previous year;
4. A discussion of why any objectives were not reached or why implementation is
behind schedule; and
5. Recommendations for new projects or revised recommendations.
CRS Coordinator’s Manual
510-30
Edition: July 2007
Floodplain Management Planning
The submittal must include other documentation to demonstrate that the evaluation
report was submitted to the governing body, released to the media, made available
to the public and/or prepared by the same planning committee that prepared the
plan.
If the community fails to submit an annual progress report with its recertification,
there is no credit (FMP = 0 and RLAA = 0). Without continued credit, a category C
repetitive loss community will revert to a Class 10.
The objective of the annual evaluation report and the five-year plan update is to ensure that
there is a continuing and responsive planning process. It is required for the community to
continue to receive the credit for its floodplain management planning. Continued credit for
floodplain management planning is dependent on the report’s being submitted with the
community’s annual CRS recertification.
The review of each recommendation in the action plan or area analysis report must state how
much was accomplished during the previous year. Where possible, the objectives and
progress toward them should be measurable (e.g., “five of the six lots slated for acquisition
were purchased” or “we improved one mile of stream channel”). Where a recommendation or
action item is not scheduled to be addressed during the year, it should still be listed and so
noted (e.g., “scheduled for 2007”).
If appropriate, new projects or revised objectives may be established. For example, if fewer
people requested technical advice than expected, the next year’s plan might have a smaller
target number. If the original plan’s projects or objectives are changed, the evaluation report
or a plan amendment must be adopted by the governing body. If an area analysis’
recommendations are changed, the change must be approved by the appropriate department
head.
Example 514.f-1. Floodville’s staff prepares the annual evaluation report by
March 1 each year. This is added to the City Manager’s March report to the City
Council, which is copied to the local media, the Chamber of Commerce, and three
neighborhood organizations that helped prepare the plan. Members of the public
may review copies in City Hall.

CRS Coordinator’s Manual
510-31
Edition: July 2007
Floodplain Management Planning
h. An update to the plan, prepared at least every five years. If it has been more than
five years since the plan was adopted, an update will be required at the time the
community applies for the credit. The five-year plan update will be scored according
to the Coordinator’s Manual currently in effect, not the version used when the
community originally applied. The update must include the following steps:
1. Steps 1 and 2: If the original planning process included a committee, then in
order to keep the credit provided under step 1, item (b) or step 2, item (a), the
update must be conducted by a committee that meets the criteria identified in
those steps.
2. Step 2: If the original planning process received credit for the final public
meeting credited under step 2, item (c), then in order to keep this credit the
community must also conduct a public meeting that reviews and receives
comments on the draft update.
3. Step 3, item (a): The update must include a review of new studies, reports, and
technical information and of the community’s needs, goals, and plans for the
area that have been published since the plan was prepared.
4. Steps 4 and 5: The hazard and problem assessments must be reviewed and
brought up to date. The assessments must account for:
•
•
•
•
•
•
•
•
new floodplain or hazard mapping,
annexation of floodprone areas,
additional repetitive loss properties,
increased development in the floodplain or watershed,
new flood control projects,
lack of maintenance of flood control projects,
major floods or other disasters that occurred since the plan was adopted,
and
any other change in flooding conditions and/or development exposed to
flooding or the other hazards covered in the plan.
5. Step 8: The action plan must be revised to account for projects that have been
completed, dropped, or changed and for changes in the hazard and problem
assessments, as appropriate.
6. Step 9: The update must be adopted by the community’s governing board.
An annual evaluation that includes these steps may qualify as the five-year update.
If the community fails to submit the five-year update by October 1 of the year
following its next cycle verification, there is no planning credit (FMP = 0). Without
continued credit under this activity, a category C repetitive loss community will
revert to a Class 10.

Summary of Activity 530
531
Credit Points. Up to 2,800 points are provided. However, there is a maximum of 1,000 points
for structural flood control projects and 200 for sewer backup protection projects.
a.
Prerequisites: Projects must protect to at least the 25-year flood level, in some cases be designed by
an engineer, and meet other requirements specific to the type of project.
b.
Retrofitting technique used (TU): The points for TU are based on the effectiveness of:
i Elevation,
i Dry floodproofing,
i Wet floodproofing, and
i Protection from sewer backup.
c.
Flood control technique used (TU): The points for TU are based on the effectiveness of:
i Barriers,
i Channel modifications, including enlarging bridges and culverts,
i Diversions,
i Storm sewer improvements, and
i Reservoirs and other storage basins that meet state dam safety requirements.
d.
Flood protection improvement (FPI): The points are adjusted based on the difference between the
flood protection provided before and after the project.
e.
The values for TU and FPI for each building are multiplied and totaled to produce the score for
protected buildings (PB)
f.
Protected buildings on the FEMA repetitive loss list are counted twice toward PB.
g.
Protected buildings in the floodplain that are critical facilities are counted twice toward PB.

Flood Protection
530 FLOOD PROTECTION
Credit is provided for protecting buildings from flood damage through either of two
methods:
•
Retrofitting the buildings so that they suffer no or minimal damage when flooded.
•
Constructing small flood control projects that keep flood waters from reaching
the buildings or lower the level of flood waters.
Background: The 300 series of activities provides credit for encouraging retrofitting
and other flood protection measures. This activity provides credit when properties are
actually protected.
Acquisition and relocation of floodprone buildings is the preferred method of flood
damage reduction. However, many buildings can be protected on-site, especially from
shallow, slow-moving flood waters. This activity provides credits for those buildings left
in the floodplain that have been protected from flood damage by retrofitting or certain
types of flood control structures.
Activity Description: The credit is based on the number of insurable buildings in the
area of regulated floodplain that have been retrofitted since the date of the
community’s original Flood Insurance Rate Map (FIRM). For the purposes of this
activity, an accessory structure such as a garage or shed is not counted as an
insurable building. Extra credit is given for protecting buildings on the repetitive loss list
of the Department of Homeland Security’s Federal Emergency Management Agency
(FEMA) (see Section 501).
Flood protection techniques that are recognized by this activity include:
Retrofitting projects:
•
•
•
•
Elevating buildings above flood levels,
Dry floodproofing,
Wet floodproofing, and
Protecting basements from sewer backup.
Structural flood control projects:
•
•
•
•
•
Barriers, including levees, berms, and floodwalls;
Channel modifications, including enlarging bridges and culverts;
Diversions;
Storm sewer improvements, including enclosing open channels; and
Small reservoirs, including retention and detention basins.
The following techniques are NOT credited under this activity:
1. Projects that protect to less than the 25-year flood level;
2. Coastal structural projects, including seawalls, groins, and beach nourishment;
CRS Coordinator’s Manual
530-2
Edition: July 2007
2. For buildings protected by a channel modification project, including diversions,
enlarging bridges and culverts, and storm sewer improvements, a licensed
professional engineer must certify that no buildings are located in areas that
would be impacted by any increases in flood elevations caused by the project.
TU = 0.8, if the project design provides at least one foot of clearance between
the flood protection level and bridge decks, top of pipe, and other
obstructions.
TU = 0.7, in all other cases.
3. For buildings protected by a reservoir, detention basin, retention pond, or other
flood water storage facility
TU = 0.8
If the flood water is stored behind a dam or other above-ground containment
structure, then the community must document that the structure meets all state
dam safety requirements. If the state does not have a dam safety program, then
a licensed professional engineer must certify that the structure meets the U.S.
Army Corps of Engineers’ dam safety criteria.
d. Flood protection improvement (FPI)
FPIi = the improved flood protection that the project provides for building i
1. For buildings that have been elevated so they meet the NFIP requirements for
new construction:
FPIi = 1.0, if the building (and its utilities, duct work, etc.) have been elevated to
one foot or more above the base flood elevation.
FPIi = 0.9, if the building (and its utilities, duct work, etc.) have been elevated to
or above the base flood elevation.
2. The credit for all other flood protection measures is adjusted for the flood protection improvement provided to each building:
FPIi = FPPi – FPBi, where
FPIi = flood protection improvement for building i
FPP = flood protection provided by the project
FPB = flood protection level before the project was constructed.
3. The values for FPP and FPB are:
0.0 for protection to less than the 10-year flood
0.3 for protection to the 10-year flood, but less than the 25-year flood
0.5 for protection to the 25-year flood, but less than the 50-year flood
0.8 for protection to the 50-year flood, but less than the 100-year flood
0.9 for protection to the 100-year flood
1.0 for protection to the 100-year flood plus one foot or more
1.0 for protection to the 500-year flood
CRS Coordinator’s Manual
530-9
Edition: July 2007
Flood Protection
4. The minimum value for FPP is 0.5. There is no credit for flood protection
measures that protect to less than the 25-year flood level.
5. The flood protection level of a barrier is the top of the barrier.
6. If a basement is protected from sewer backup by an overhead sewer or backup
valve, then FPP = 1.0
If a structural flood control project modifies the 100-year floodplain, the community is
obligated to notify FEMA of the changes (44 CFR 65.3).
Example 531-1.
Example 1: A building on a crawlspace was elevated from the 10-year flood
elevation to one foot above 100-year flood elevation.
FPI = 1.0
Example 2: A building has been protected by a 25-year berm (changing its
protection level from 0 to the 25-year flood level).
FPP = 0.5, FPB = 0, FPI = FPP – FPB = 0.5 – 0 = 0.5
Example 3: A channel improvement lowers the 100-year flood by 2 feet. Instead of
having the 50-year flood go over the lowest floor, buildings are now dry during the
100-year flood. For these buildings:
FPP = 0.9, FPB = 0.8,
FPI = FPP – FPB = 0.9 – 0.8 = 0.1
Example 4: Another building closer to the stream is affected by the same channel
improvement. The two-foot drop in flood levels means that this building is now
subject only to the 60-year flood instead of the 35-year flood.
FPP = 0.8, FPB = 0.5, FPI = FPP – FPB = 0.8 – 0.5 = 0.3
.
d. Protected buildings
PB = Σ(TUi x FPIi). That is, PB, the variable for protected buildings, is the sum of the
TU value for each building times the FPI value for that building. The maximum value
for (TUi x FPIi) for any single building is 1.0 (i.e., the building was elevated (TUi =
1.0) and it was elevated to one foot above the base flood level (FPIi = 1.0)).
Summing the factors for each building is shown in the formula with the mathematical symbol
“Σ” (sigma). The calculations are easier to understand and compute in the activity worksheets.
CRS Coordinator’s Manual
530-10
Edition: July 2007
Flood Protection
NOTE: See Section 505 on projects funded by FEMA’s Flood Mitigation Assistance program.
e. If a protected building in the regulatory floodplain is also on the FEMA repetitive loss
list, it is counted twice toward PB. If a protected building outside of the regulatory
floodplain is also on the FEMA repetitive loss list, it is counted once toward PB.
If a protected building is a Severe Repetitive Loss Property and in the regulatory
floodplain, it is counted three times toward PB. If a protected building outside of the
regulatory floodplain is also a Severe Repetitive Loss Property, it is counted twice
toward PB. These multipliers are provided only if the flood protection measure was
sufficient to remove the property from the repetitive loss list.
Section 501 explains the FEMA repetitive loss list. It is a list of properties that have received
repetitive flood insurance claims. Communities with one or more properties on the list review
the list as a prerequisite to entering the CRS.
Figure 500-1 explains Severe Repetitive Loss Properties, a subset of the repetitive loss
properties that includes those that have been particularly hard hit by repetitive flooding and
are prime candidates for flood protection. Additional credit is provided for each Severe
Repetitive Loss Property that has been protected. For example, if five floodplain properties
on the repetitive loss list were elevated and one was a Severe Repetitive Loss Property, then
they would be counted as (4 x 2) + (1 x 3) = 11 buildings counted toward PB.
If a repetitive loss property in the regulatory floodplain, it is simply listed twice on the
activity worksheet, AW-530-2, and noted as “repetitive loss.” If it is not in the community’s
regulatory floodplain, it is listed once. The same approach is used for Severe Repetitive Loss
Properties, except that if one is in the regulatory floodplain, it is listed three times (twice if it
is outside the floodplain).
No separate documentation is needed for this extra repetitive loss credit. It is verified by a
review of the community’s corrected repetitive loss list and field verified with the other
buildings credited for PB. A community with no properties on the FEMA repetitive loss list is
not eligible for this extra credit.
Example 531-2. A review of Floodville’s building permits identified 5 retrofitted
buildings. They are listed by address and numbered on AW-530-2. Buildings 1–4 are
in or near Area #1 in Figure 500-1. Because Area #1 is subject to ice jams, it is a
high hazard area. The retrofitting projects were all designed by a licensed engineer.
Buildings 1 and 2 were elevated several years ago. The buildings were subject to
damage by the 10-year flood until they were raised above the level of an earlier
flood, which was about a 50-year event. (The projects were not substantial
improvements, so there was no code requirement to go to the 100-year flood level).
CRS Coordinator’s Manual
530-11
Edition: July 2007
Flood Protection
TU1-2 = 1.0
FPP1-2 = 0.8, FPB1-2 = 0
FPI1-2 = FPP1-2 – FPB1-2 = 0.8 – 0 = 0.8
TU1-2 x FPI 1-2 = 1.0 x 0.8 = 0.8
Buildings 3 and 4 were elevated after the last flood. They were not as low as
buildings 1 and 2. It is estimated that they were at a 10–20-year flood level. The City
used FEMA Hazard Mitigation Grant funds to encourage voluntary retrofitting.
Buildings 3 and 4 were elevated 2 feet above the base flood level.
TU3-4 = 1.0
FPI3-4 = 1.0
TU3-4 x FPI 3-4 = 1.0 x 1.0 = 1.0
Building 1 and Building 3 are on FEMA’s repetitive loss list, so they are listed twice
on AW-530-2.
Buildings 5–14 are in or near Area #2. Although Area #2 is outside the SFHA, it is
subject to Floodville’s floodplain regulations. Buildings in this floodplain are therefore
eligible for credit under this activity. The area flooded an average of every 5 years,
so the buildings are considered to have been protected to less than the 10-year flood
level
Buildings 5–14 benefited from a culvert enlargement. The City had surveyed each
building in this area. The channel and the culvert can now handle the 25-year flood
without its reaching these buildings. The other buildings in this floodplain, closer to
the channel, are still subject to flooding by the 25-year flood.
TU5-14 = 0.7
FPP5-14 = 0.5, FPB5-14 = 0
FPI5-14 = FPP5-14 – FPB5-14 =0.5 – 0 = 0.5
TU5-14 x FPI 5-14 = 0.7 x 0.5 = 0.35
Buildings 8, 13 and 14 are on FEMA’s repetitive loss list, so they are listed twice on
AW-530-2.
The calculations are done on AW-530-2. PB = 9.95.
f. If a protected building in the regulatory floodplain is also a critical facility, it is
counted twice toward PB. If a protected building outside of the regulatory floodplain
is also a critical facility, it is counted once toward PB.
CRS Coordinator’s Manual
530-12
Edition: July 2007
Flood Protection
For CRS credit purposes, critical facilities are defined in Section 130. This section provides a
bonus for protecting structures such as emergency operations centers, hospitals, and buildings
where hazardous materials are stored. Like repetitive loss buildings, buildings that are critical
facilities are scored twice.
532 Impact Adjustment
a. Option 1:
rPB = 0.15 x the number of buildings protected using one or more of the techniques
described in Section 531.b or c. The projects must meet all of the prerequisites in
Section 531, including protecting to at least the 25-year flood level. A maximum of
20 different properties can be counted toward Option 1. This can be any
combination of properties in the regulatory floodplain, repetitive loss buildings, and
Severe Repetitive Loss Properties.
If the community uses Option 1, it will receive 4.2 points for each protected building. The
maximum value under Option 1 is limited to the scores for 20 different properties. For
example, the community may count 14 buildings removed from the regulatory floodplain, 5
repetitive loss properties, and 1 Severe Repetitive Loss Property. Using the repetitive loss
multipliers in Section 531.e, these 20 properties equate to 14 + (5 x 2) + (1 x 3) = 27
protected buildings. rPB = 0.15 x 27 = 4.05.
The community does not need to complete activity worksheet AW-530-2, nor does its
application specify the addresses or the values for TU and FPI for the protected buildings.
However, the community must still have this information available for the credited buildings
during the verification visit and it must be able to show that the retrofitting or structural flood
control projects meet all of the relevant prerequisites.
b. Option 2:
bSF = the number of buildings in the SFHA, as described in Section 303.
rPB = 100 x PB. rPB cannot be greater than 100.0.
bSF
The credit points for this activity are based on the ratio of the protected buildings’ points
(rPB) to the number of buildings in the SFHA. This is done by dividing the points for
protected buildings (PB) by the number of buildings in the SFHA (bSF). bSF is the same variable used in Activities 520, 610, and 620, and is described in more detail in Sections 302–
303. Even if the community is requesting credit for buildings outside the SFHA, the impact
adjustment is based on bSF, the number of buildings in the SFHA.
CRS Coordinator’s Manual
530-13
Edition: July 2007
Flood Protection
It is theoretically possible that there are more protected buildings than buildings in the SFHA
and that the number of retrofitted buildings could be greater than bSF. However, rPB cannot
be greater than 100.0. Note that buildings not on FEMA’s repetitive loss list that are outside
of the SFHA can only be counted toward PB if they are in an area subject to floodplain
regulations (aRF) as shown on the community’s Impact Adjustment Map (see Section 403).
Example 532.b-1. Someburg has protected ten buildings from the 50-year flood
with a channel improvement, has two buildings elevated above the 100-year flood
level, and has constructed a barrier around the public works garage to protect it from
the 25-year flood. Someburg has 13 buildings that are protected by techniques that
meet the criteria of Section 531.b or c. The Someburg building official has permit
records for each project. None of the projects requires human intervention, nor are
the buildings located in a high hazard area.
Under Option 1, rPB = 0.15 x 13 = 1.95
Example 532.b-2. As noted in the previous section, Floodville’s PB score is
9.95. As noted in Section 522, there are 282 buildings in Floodville’s SFHA: bSF =
282.
Under Option 2, rPB = 100 x 9.95 = 995 = 3.53
282
282
533 Credit Calculation
c530 = 28 x rPB
Example 533-1. Someburg uses Option 1 for the impact adjustment:
rPB = 1.95
c530 = 28 x 1.95 = 54.6, rounded to 55
Example 533-2. Floodville receives more credit points using Option 2. As
discussed above, rPB for Floodville is 3.53.
c530 = 28 x 3.53 = 98.84, rounded to 99
Example 533-3. Bigtown constructs a series of flood control reservoirs and
detention basins to reduce flood levels on Swampy Creek. Some wetlands are
preserved and some more are created to act as natural retention areas. There are

610 FLOOD WARNING PROGRAM
Summary of Activity 610
611
Credit Points. There are five elements in this activity for a maximum of 255 points.
a.
Flood threat recognition system (FTR): Up to 40 points are provided for a flood threat recognition
system that forecasts flood elevations and arrival times at specific locations within the community.
b.

impact adjustment ratio for an element is 1.0.
b.
Under Option 2, if the program is not implemented throughout the SFHA, a default impact adjustment
ratio of 0.25 may be used.
c.
Under Option 3, if the program is not implemented throughout the SFHA, the impact adjustment ratios
may reflect the number of buildings in the SFHA affected.
613
Credit Calculation. The credit points for each element are multiplied by the impact adjustment
ratios and their products are totaled.
614
Credit Documentation. The community must submit the following.
a.
A description of the flood threat recognition system that tells how site-specific forecasts with flood
elevations or flood flows and arrival times are generated by meteorologic and/or hydrologic data.

Flood Warning Program
610 FLOOD WARNING PROGRAM
NOTE: A separate publication, CRS Credit for Flood Warning Programs, gives an example
of a community program and application documentation. Communities are encouraged to
read this document before applying for this activity. It will improve the quality of the
application and reduce the need for additional documentation later. For a free copy, see
Appendix E.
Credit is provided for a program that provides timely identification of impending flood
threats, disseminates warnings to appropriate floodplain occupants, and coordinates
flood response activities.
Background: With sufficient warning of a flood, a community and its floodplain
occupants can take protective measures such as moving furniture, cars, and people
out of harm’s way. When a flood threat recognition system is combined with an
emergency response plan that addresses the community’s flood problems, a great deal
of flood damage can often be prevented.
The National Weather Service issues specific flood warnings for specific locations along
major rivers and coastlines. There is a small but growing number of communities with their
own flood threat recognition systems, which enable advance identification of floods on
smaller rivers. The full benefit of early flood warning is only realized if the community
disseminates the warning to the general public and to critical facilities. Additional flood
damage can be prevented if the community has a flood response plan that includes appropriate tasks, such as directing evacuation, sandbagging, and moving building contents above
flood levels.
Activity Description: The community must have a flood threat recognition system
that identifies an impending flood in order to receive credit under this activity. Additional
credit is provided for disseminating a warning to the general public, carrying out
appropriate flood response tasks, and coordinating the flood response plan with
operators of critical facilities. A report on the operation of the system is required if a
flood meeting the criteria in Section 614.d occurred during the previous year.
This activity is not intended to be a model for developing a flood warning or flood response
program. As with the rest of the Community Rating System (CRS) activities, its objective is
to provide a simple way to measure a local program’s potential impact on flood insurance
premiums. An effective flood warning or response program needs to be carefully prepared
and tailored to the local flood hazards and the specific needs of the community.
The minimum requirement for credit for this activity is a flood threat recognition system to
identify impending flooding. The system can use locally collected data or data from the
National Weather Service or other rain, river, or storm monitoring agency.
CRS Coordinator’s Manual
610-2
Edition: July 2007
Even where a multi-hazard plan or other comprehensive emergency response plan is used for
parts of the documentation, other documentation may be required. Many of the specific items
required to document these elements may be in appendices or standard operating procedures
rather than in the body of the plan.
If a multi-hazard emergency response plan or comprehensive emergency management plan
with many annexes is used to document the credit for this activity, the entire document should
not be submitted with the CRS application. The specific documentation should be marked
with the CRS acronyms in the margins, and copies of only those pages should be submitted.
3. A copy of the materials that publicize the warning system. The publicity must
fully cover the topics of flood warning and flood safety as discussed in Section
331. The materials must be distributed each year and must reach at least 90%
of the target audience.
c. [If the community determines the impact adjustment ratios using Options 1 or 3
(Section 612.a or 612.c)] Documentation showing how the impact adjustments
were determined. If Option 3 is used, a map showing the areas covered by the flood
warning program is needed.
If Option 1 is used, a written statement that all buildings in the SFHA are covered by the
program is sufficient.
The community must submit the following with its annual CRS recertification:
d. [If the community has credit for other response efforts (ORE)] A description of the
exercise, drill, or response to an actual emergency or disaster conducted during the
previous year. The description must include a list of who participated and any
lessons learned from the exercise, drill, emergency, or disaster.
e. [If the community has credit for critical facilities planning (CFP1)] A page from the
list of the operators of the critical facilities affected by flooding that must be updated
at least annually (see Sections 214 and 611.d.2(a)).
f. If the community experienced at least one flood during the previous year that
damaged more than 10 buildings, caused more than $50,000 in property damage,
or caused the death of one or more persons, it must submit the following
documentation with its annual CRS recertification (see Section 214):
An evaluation report that describes the performance of the warning program. For
each flood meeting the above criteria, this report must describe how the program
operated in response to the flood, and any improvements that may be needed.
If there has been a flood that meets the above criteria, submission of the report with the
annual recertification is necessary for continued credit under this activity. The report should
include a discussion of the following items. The report does not need to cover items 3 through
5 if the community is not receiving CRS credit for these elements.

620 LEVEE SAFETY
Summary of Activity 620
621
a.
Credit Points. There is one element in this activity for a maximum of 900 points.
Levee protection level (LPL): Up to 100 points are provided based on the flood recurrence
interval at the flood protection level. The levee’s flood protection level is 3 feet below the lowest
point of the crown. The following conditions must be met:
b. The levee must have been constructed before January 1, 1991.
c.
The community must have a levee emergency plan that specifies actions to be taken at various
flood stages.
d. Each year the community must notify properties protected by the levee of the residual flood
hazard.
622
Impact Adjustment. The credit points for each element are adjusted in one of three ways.
a.
Under Option 1, if all of the buildings in the Special Flood Hazard Area (SFHA) are protected by
the levee, the impact adjustment ratio is 1.0.
b. Under Option 2, if there are at least five buildings protected by the levee, a default impact
adjustment ratio of 0.01 may be used and the community receives 9 points for this activity.
c.
623
Under Option 3, the impact adjustment ratio reflects the number of buildings in the SFHA
protected by the levee.
Credit Calculation. The credit points for LPL are multiplied by the impact adjustment ratio
and then by 9.
624
a.
Credit Documentation. The community must submit the following.
Levee protection level documentation. EITHER:
1. A statement signed by the U.S. Army Corps of Engineers that states the levee protection level

620 LEVEE SAFETY
Credit is provided for maintaining levees and a levee emergency response plan for
areas protected by less than base flood levees.
Background: If a levee or floodwall does not meet the base flood protection criteria, it
is not recognized on the Flood Insurance Rate Map (FIRM). Because these levees do
prevent damage from smaller, more frequent floods, they may receive CRS credit.
Many communities are protected to some extent by levees or floodwalls. (As used in this
activity, the word “levee” includes floodwalls.) The National Flood Insurance Program
(NFIP) has criteria (44 CFR 65.10, shown in Figure 620-2a–c) for recognizing whether a
levee provides protection from the base flood. If it does, the protected area is mapped as a B,
C, or X Zone and flood insurance rates are lower than if it remained an A Zone. The
community is required to maintain the levee to its design standard in order to keep the
favorable zone designation.
Activity Description: This activity provides credit to communities protected by levees
that are properly maintained and operated but are not high enough to meet the criteria
for base flood levees. A community may also receive credit for a levee that protects to
the base flood elevation or above if the levee is not reflected on the community’s FIRM.
There is no credit under this activity if the area protected by the levee is designated as
an AO, A99, AR, B, C, or X Zone or an AE or A numbered zone with the base flood
elevation lower than on the water side of the levee.
CRS credit is only provided for levees and floodwalls built before January 1, 1991, and
those that provide protection to at least the 25-year flood elevation. SEE THE NOTE IN
SECTION 621.
In addition to having adequate design and maintenance, there must be emergency response
plans for situations in which the levees are threatened with overtopping or failure.
This activity is not intended to encourage construction of new flood control structures or to
duplicate credit given to base flood levees by current mapping procedures.
The area protected by a levee on a community’s FIRM must show the protected area as an
SFHA. The base flood elevation must be the same on both sides of the levee. If the area
protected by a levee is mapped as a B, C, or X Zone, the levee was considered to provide base
flood protection when the FIRM was prepared and no credit is available under this activity.
There are other activities related to levees that are not included here because they are credited
elsewhere. For example, Activity 330 (Outreach Projects) could provide credit for advising
residents of the protected area about the levee and its shortcomings.

621 Credit Points
Maximum credit for Activity 620: 900 points.
Levee protection level (LPL) (Maximum credit: 100 points)
For LPL credit, the following conditions must be met:
a. LPL = flood recurrence interval at the flood protection level. If the flood protection
level is at or above the base flood elevation, LPL = 100. There is no credit
for levees below the 25-year protection level. The flood protection level can
be determined in either of the following ways:
1. The levee’s flood protection level may be determined by the U.S. Army
Corps of Engineers or other federal agency that has inspected the levee;
or
2. In the absence of a determination by a federal agency with jurisdiction,
the levee’s flood protection level is 3 feet below the lowest point of the
crown.
The criteria in 44 CFR 65.10(b)(1) require that the crown of the levee be at least 3 feet above
the base flood elevation. To be credited under this activity, the levee would not need to be
that high, but it must meet the rest of the requirements of §65.10.
crown
protection level
¦
3 feet
Figure 620-1. Levee protection level.
In the absence of a statement from the Corps or other federal agency with jurisdiction, the
protection elevation of the levee is considered to be 3 feet below the crown of the levee (see
Figure 620-1). For example, if the levee’s crown is 3 feet above the 50-year flood level, LPL
= 50. In 44 CFR 65.10(b)(1), there is a discussion of the circumstances under which a smaller
freeboard is acceptable.
CRS Coordinator’s Manual
620-3
Edition: July 2007
Levee Safety
The recurrence interval for the protection elevation can be determined from the flood
insurance study’s profile. In any case, the flood protection elevation must be provided by the
community.
Example 621.a-1. The elevation of the crown of Riverview’s levee is 532 feet
NGVD. Three feet below the crown is elevation 529. A check of the profile shows
that 529 is halfway between the 50- and 100-year flood elevations. Therefore, LPL =
75.
To be eligible for credit under this activity, the levee must provide protection from at least a
25-year flood. Base flood levees may already be credited under the NFIP because areas in the
floodplain that are protected by them are usually mapped B, C, or X Zones and flood
insurance premium rates are substantially lower than those for unprotected floodplain
properties.
Example 621.a-2. The elevation of 3 feet below the crown of Floodville’s levee
approximates the 10-year flood elevation on the profile. Therefore, LPL = 0 and there
is no credit for this activity. Floodville may review the freeboard criteria in 44 CFR
65.10(b)(1) to see if the Department of Homeland Security’s Federal Emergency
Management Agency (FEMA) would accept 2 feet of freeboard.
NOTE: The area protected by the levee may be mapped as an A, AE, or numbered A Zone to
reflect internal drainage problems. If it is an AO Zone, it definitely reflects internal drainage
problems. Where the SFHA is based on an internal drainage problem, the protected area has
a base flood elevation lower than the river’s and the levee has been mapped as providing
protection from the base flood. This activity does not provide credit for levees in these cases.
If the area protected by the levee is later remapped as an X, A99, AR, or AO Zone or other
SFHA that only reflects internal drainage, the community will lose its CRS credit for this
activity. Remapping the floodplain due to a flood protection project provides a separate and
greater flood insurance premium rate reduction (see Section 530).
It is important to note that operation and maintenance “must be under the jurisdiction of a
Federal or State agency, an agency created by Federal or State law, or an agency of a
community participating in the NFIP.” A levee maintained by a levee district is acceptable;
one maintained by a homeowner’s association is not.
b. The levee must have been constructed before January 1, 1991.
c. The community must have a levee emergency plan that specifies actions to be
taken at various flood stages. Actions that must be included are:
1. Periodic patrols of the structure;
CRS Coordinator’s Manual
620-4
Edition: July 2007
Levee Safety
2. Closing openings that are structural parts of the system (sandbagging is not
acceptable);
3. Warning local emergency officials when the flood reaches within 4 feet of the
crown of the levee;
4. Monthly communications checks with local emergency officials;
5. Annual inspections of emergency equipment and stockpiles; and
6. Annual drills.
The NFIP rules in 44 CFR 65.10(c), Operation plans and criteria, specify what needs to be
done to protect the levee from failure. For example, the standards for allowable closures are
found in 65.10(c)(1).
Items c.1 through c.6 specify what needs to be done to protect lives and property in the
protected area if the levee fails or is overtopped. Acting when a flood is within 4 feet of the
crown allows time to advise local officials that the levee protection is being threatened. A
different threshold for advance notice of failure or overtopping may be submitted for review.
If the community requests credit for a flood response plan under Activity 610 (Flood Warning
Program), items 1, 2, and 3 should be incorporated into that plan. Items 4, 5, and 6 should be
coordinated with the maintenance, testing, and drills of the community’s flood response plan.
However, the emergency plan for the levee must be designed and implemented by the agency
that operates and maintains the levee, which may or may not be the community.
d. Each year, the community must notify properties protected by the levee of the
residual flood hazard. The annual project must meet the credit criteria for an
outreach project to floodplain properties (OPF) credited under Section 331.b. The
notice must clearly explain that the property is subject to flooding from a flood that
exceeds the levee protection level or that results from a levee failure.
622 Impact Adjustment
a. Option 1:
If all of the buildings in the community’s SFHA are protected by a single levee or a
levee system built to a single flood protection level, rLP = 1.0.
CRS Coordinator’s Manual
620-5
Edition: July 2007
Levee Safety
b. Option 2:
rLP = 0.01, where bLP ≥ 5 and bLP = the number of buildings protected by the
levee.
c. Option 3:
rLP = bLP, where bLP = the number of buildings protected by the levee.
bSF
bSF = the number of buildings in the SFHA.
If the levee protects all of the buildings in the SFHA, the impact adjustment ratio rLP = 1.0
(Option 1).
If at least five buildings are protected by the levee (i.e., bLP = 5 or more), then a default
impact adjustment ratio of 0.01 may be used. If the community has fewer than 500 buildings
in its SFHA (i.e., bSF < 500), it will receive more credit points by using Option 3. If the levee
protects more than 1% of the buildings in the SFHA, it will receive more credit points under
Option 3. However, Option 2 may still be used if the community does not want to calculate
bSF.
Otherwise, rLP is calculated by dividing the number of buildings that the levee protects (bLP)
by the number of buildings in the SFHA (bSF) (Option 3). There is no credit for protecting
buildings not in the SFHA as shown on the FIRM.
A discussion of impact adjustment ratios using buildings, including the variable bSF, appears
in Sections 301 through 303.
Example 622.b-1. Riverview’s levee protects 82 buildings in the SFHA:
bLP = 82. There are 150 buildings in Riverview’s SFHA: bSF = 150. Using Option 3,
rLP = 82 = 0.55
150
623 Credit Calculation
c620 = 9 x LPL x rLP
CRS Coordinator’s Manual
620-6
Edition: July 2007
Levee Safety
Example 623-1. Riverview’s levee protects 82 buildings to approximately the 75year flood level: LPL = 75. As noted above, rLP = 0.55.
c620 = 9 x 75 x 0.55 = 371.25 = 371
624 Credit Documentation
The community must submit the following documentation with its application:
a. EITHER:
1. A statement signed by the U.S. Army Corps of Engineers or other federal
agency with jurisdiction that has inspected the levee that
(a) States the levee protection level; and
(b) Provides the date of construction; OR
2. A certification by a licensed professional engineer that
(a) States that the levee or floodwall meets all the NFIP levee recognition
requirements (44 CFR 65.10) except for height (65.10(b)(1));
(b) Provides the date of construction; and
(c) Provides the protection elevation and the flood recurrence interval for that
elevation. Data sources and calculations must be included.
The levee must be certified by a licensed professional engineer as meeting all of the NFIP’s
requirements for levee recognition as iterated in 44 CFR 65.10. These requirements are
reprinted in Figure 620-2 and cover the levee design, operation, and maintenance in
subsections (b), (c), and (d), respectively.
b. A copy of the community’s levee emergency plan meeting the specifications of
Section 621.c.
c. A copy of the officially adopted levee maintenance plan meeting the specifications
of 44 CFR 65.10(d).
d. A map showing the area the levee protects, designated as “LP.” No credit is
provided for levees that protect vacant land or properties in B, C, or X Zones.
CRS Coordinator’s Manual
620-7
Edition: July 2007
Levee Safety
The credit points for this activity are adjusted in Section 622 according to the number of
buildings protected (bLP). To assist in calculating and verifying the number of buildings
protected, the area protected by the levee must be shown on a map.
The map may be the community’s FIRM or the Impact Adjustment Map prepared in
accordance with the instructions in Section 403. The data for the map can be found in the
original design study for the levee. As an alternative, bLP can be the buildings in the area
below the flood protection elevation as extrapolated from the best available contour map.
e. [If the community determines the impact adjustment ratios using Options 2 or 3
(Section 622.b or 622.c)] Documentation showing how bLP was determined. If the
community used Option 3, documentation showing how bSF was determined.
The variable bSF represents the number of buildings in the SFHA. It is discussed in detail in
Sections 302 and 303.
The community must submit the following documentation with its annual CRS
recertification (see Section 214):
f. A certification by a licensed professional engineer that the levee has been
maintained in accordance with the officially adopted levee maintenance plan and
that all mechanized interior drainage systems have been tested.
As an alternative to certification, the community may use a copy of the Corps’ annual
inspection report, provided that it shows that the levee has been maintained and received an
“acceptable” rating, or a letter from the Corps that states that the levee has been maintained
in accordance with the officially adopted levee maintenance plan.
g. Documentation of the monthly communications checks between the agency
responsible for the levee and local emergency officials and a description of the
exercise or drill of the levee emergency plan or the response to an actual
emergency or disaster conducted during the previous year. The description must
include a list of who participated and any lessons learned from the exercise, drill,
emergency, or disaster.
h. A copy of the materials that notify occupants of the area protected by the credited
levee. The materials must be distributed each year and must reach at least 90% of
the properties in the protected area. An outreach project to floodplain properties
credited under Activity 330 (Outreach Projects) may qualify for this credit provided
that it clearly notifies the recipients that they are exposed to a levee failure flood
hazard.
CRS Coordinator’s Manual

Levee Safety
The following may be cause for loss of credit under this activity:
•
•
•
•
Failure to properly maintain the levee;
Failure to conduct the monthly checks and annual inspections and drills;
Failure to distribute the annual notification to the occupants of the area protected by
the credited levee;or
Failure to submit the appropriate documentation each year.
Many levees have been funded or partially funded by the Corps of Engineers or other federal
or state agencies. To ensure that their investment is being properly maintained, these agencies
often conduct inspections and send inspection results to the levee owner (e.g., the levee
district). Copies of these results suffice as documentation that the levee is being maintained
but not necessarily that the checks, inspections, and drills have been conducted.

Edition: July 2007
Levee Safety
44 CFR § 65.10 Mapping of Areas Protected by Levee Systems.
(a) General. For purposes of the NFIP,
FEMA will only recognize in its flood hazard and
risk mapping effort those levee systems that meet,
and continue to meet, minimum design, operation,
and maintenance standards that are consistent
with the level of protection sought through the
comprehensive flood plain management criteria
established by § 60.3 of this subchapter.
Accordingly, this section describes the types of
information FEMA needs to recognize, on NFIP
maps, that a levee system provides protection
from the base flood. This information must be
supplied to FEMA by the community or other
party seeking recognition of such a levee system
at the time a flood risk study or restudy is
conducted, when a map revision under the
provisions of Part 65 of this subchapter is sought
based on a levee system, and upon request by the
Administrator during the review of previously
recognized structures. The FEMA review will be
for the sole purpose of establishing appropriate
risk zone determinations for NFIP maps and shall
not constitute a determination by FEMA as to
how a structure or system will perform in a flood
event.
(b) Design criteria. For levees to be
recognized by FEMA, evidence that adequate
design and operation and maintenance systems
are in place to provide reasonable assurance that
protection from the base flood exists must be
provided. The following requirements must be
met:
(1) Freeboard. (i) Riverine levees must
provide a minimum freeboard of three feet above
the water-surface level of the base flood. An
additional one foot above the minimum is
required within 100 feet in either side of
structures (such as bridges) riverward of the levee
or wherever the flow is constricted. An additional
one-half foot above the minimum at the upstream
end of the levee, tapering to not less than the
minimum at the downstream end of the levee, is
also required.
(ii) Occasionally, exceptions to the minimum
riverine freeboard requirement described in
paragraph (b)(1)(i) of this section, may be
approved. Appropriate engineering analyses
demonstrating adequate protection with a lesser
freeboard must be submitted to support a request
for such an exception. The material presented
must evaluate the uncertainty in the estimated
base flood elevation profile and include, but not
necessarily be limited to an assessment of
statistical confidence limits of the 100-year
discharge;
changes
in
stage-discharge
relationships; and the sources, potential, and
magnitude of debris, sediment, and ice
accumulation. It must be also shown that the
levee will remain structurally stable during the
base flood when such additional loading
considerations are imposed.
Under no
circumstances will freeboard of less than two feet
be accepted.
(iii) For coastal levees, the freeboard must be
established at one foot above the height of the one
percent wave or the maximum wave runup
(whichever is greater) associated with the
100-year stillwater surge elevation at the site.
(iv) Occasionally, exceptions to the minimum
coastal levee freeboard requirement described in
paragraph (b)(1)(iii) of this section, may be
approved. Appropriate engineering analyses
demonstrating adequate protection with a lesser
freeboard must be submitted to support a request
for such an exception. The material presented
must evaluate the uncertainty in the estimated
base flood loading conditions.
Particular
emphasis must be placed on the effects of wave
attack and overtopping on the stability of the
levee. Under no circumstances, however, will a
freeboard of less than two feet above the 100-year
stillwater surge elevation be accepted.
(2) Closures. All openings must be provided
with closure devices that are structural parts of
the system during operation and design according
to sound engineering practice.
Figure 620-2a. FEMA’s levee safety criteria (page one).
CRS Coordinator’s Manual
620-10
Edition: July 2007
Levee Safety
(3) Embankment protection. Engineering
analyses must be submitted that demonstrate that
no appreciable erosion of the levee embankment
can be expected during the base flood, as a result
of either currents or waves, and that anticipated
erosion will not result in failure of the levee
embankment or foundation directly or indirectly
through reduction of the seepage path and
subsequent instability.
The factors to be
addressed in such analyses include, but are not
limited to: Expected flow velocities (especially in
constricted areas); expected wind and wave
action; ice loading; impact of debris; slope
protection techniques; duration of flooding at
various stages and velocities; embankment and
foundation materials; levee alignment, bends, and
transitions; and levee side slopes.
(4) Embankment and foundation stability.
Engineering analyses that evaluate levee
embankment stability must be submitted. The
analyses provided shall evaluate expected seepage
during loading conditions associated with the
base flood and shall demonstrate that seepage into
or through the levee foundation and embankment
will not jeopardize embankment or foundation
stability. An alternative analysis demonstrating
that the levee is designed and constructed for
stability against loading conditions for Case IV as
defined in the U.S. Army Corps of Engineers
(COE) manual, “Design and Construction of
Levees” (EM 1110-2-1913, Chapter 6, Section
II), may be used. The factors that shall be
addressed in the analyses include: Depth of
flooding, duration of flooding, embankment
geometry and length of seepage path at critical
locations, embankment and foundation materials,
embankment compaction, penetrations, other
design factors affecting seepage (such as drainage
layers), and other design factors affecting
embankment and foundation stability (such as
berms).
(5) Settlement. Engineering analyses must be
submitted that assess the potential and magnitude
of future losses of freeboard as a result of levee
settlement and demonstrate that freeboard will be
maintained within the minimum standards set
forth in paragraph (b)(1) of this section. This
analysis must address embankment loads,
compressibility
of
embankment
soils,
compressibility of foundation soils, age of the
levee system, and construction compaction
methods. In addition, detailed settlement analysis
using procedures such as those described in the
COE
manual,
“Soil
Mechanics
Design--Settlement Analysis” (EM 1100-2-1904)
must be submitted.
(6) Interior drainage. An analysis must be
submitted that identifies the source(s) of such
flooding, the extent of the flooded area, and, if the
average depth is greater than one foot, the
water-surface elevation(s) of the base flood. This
analysis must be based on the joint probability of
interior and exterior flooding and the capacity of
facilities (such as drainage lines and pumps) for
evacuating interior floodwaters.
(7) Other design criteria.
In unique
situations, such as those where the levee system
has relatively high vulnerability, FEMA may
require that other design criteria and analyses be
submitted to show that the levees provide
adequate protection. In such situations, sound
engineering practice will be the standard on
which FEMA will base its determinations.
FEMA will also provide the rationale for
requiring this additional information.
(c) Operation plans and criteria. For a levee
system to be recognized, the operational criteria
must be as described below. All closure devices
or mechanical systems for internal drainage,
whether manual or automatic, must be operated in
accordance with an officially adopted operation
manual, a copy of which must be provided to
FEMA by the operator when levee or drainage
system recognition is being sought or when the
manual for a previously recognized system is
revised in any manner. All operations must be
under the jurisdiction of a Federal or State
agency, an agency created by Federal or State
law, or an agency of a community participating in
the NFIP.
Figure 620-2b. Page two of FEMA’s levee safety criteria.
CRS Coordinator’s Manual
620-11
Edition: July 2007
Levee Safety
(1) Closures. Operation plans for closures
must include the following:
(i) Documentation of the flood warning
system, under the jurisdiction of Federal, State, or
community officials, that will be used to trigger
emergency operation activities and demonstration
that sufficient flood warning time exists for the
completed operation of all closure structures,
including necessary sealing, before floodwaters
reach the base of the closure.
(ii) A formal plan of operation including
specific actions and assignments of responsibility
by individual name or title.
(iii) Provisions for periodic operation, at not
less than one year intervals, of the closure
structure for testing and training purposes.
(2) Interior drainage systems. Interior
drainage systems associated with levee systems
usually include storage areas, gravity outlets,
pumping stations, or a combination thereof.
These drainage systems will be recognized by
FEMA on NFIP maps for flood protection
purposes only if the following minimum criteria
are included in the operation plan:
(i) Documentation of the flood warning
system, under the jurisdiction of Federal, State, or
community officials, that will be used to trigger
emergency operation activities and demonstration
that sufficient flood warning time exists to permit
activation of mechanized portions of the drainage
system.
(ii) A formal plan of operation including
specific actions and assignments of responsibility
by individual name or title.
(iii) Provision for manual backup for the
activation of automatic systems.
(iv) Provisions for periodic inspection of
interior drainage systems and periodic operation
of any mechanized portions for testing and
training purposes. No more than one year shall
elapse between either the inspections or the
operations.
(3) Other operation plans and criteria. Other
operating plans and criteria may be required by
FEMA to ensure that adequate protection is
provided in specific situations. In such cases,
sound emergency management practice will be
the standard upon which FEMA determinations
will be based.
(d) Maintenance plans and criteria. For levee
systems to be recognized as providing protection
from the base flood, the maintenance criteria must
be as described herein. Levee systems must be
maintained in accordance with an officially
adopted maintenance plan, and a copy of this plan
must be provided to FEMA by the owner of the
levee system when recognition is being sought or
when the plan for a previously recognized system
is revised in any manner. All maintenance
activities must be under the jurisdiction of a
Federal or State agency, an agency created by
Federal or State law, or an agency of a
community participating in the NFIP that must
assume ultimate responsibility for maintenance.
This plan must document the formal procedure
that ensures that the stability, height, and overall
integrity of the levee and its associated structures
and systems are maintained. At a minimum,
maintenance plans shall specify the maintenance
activities to be performed, the frequency of their
performance, and the person by name or title
responsible for their performance.
(e) Certification requirements. Data submitted
to support that a given levee system complies
with the structural requirements set forth in
paragraphs (b)(1) through (7) of this section must
be certified by a registered professional engineer.
Also, certified as-built plans of the levee must be
submitted. Certifications are subject to the
definition given at § 65.2 of this subchapter. In
lieu of these structural requirements, a Federal
agency with responsibility for levee design may
certify that the levee has been adequately
designed and constructed to provide protection
against the base flood.

630 DAM SAFETY
Summary of Activity 630
631
Credit Points. There are two elements in this activity for a maximum of 175 points.
a. State dam safety program (SDS): Up to 75 points are provided if the community is in a
state with a dam safety program that has been accepted by FEMA for Community Rating
System (CRS) credit. The state dam safety office must have stated that the community’s
program is in compliance with the state program.
b. Dam failure emergency action plan (DFP): Up to 100 points are provided for the

are adjusted in one of three ways.
a. Under Option 1, if the plan covers all buildings in the Special Flood Hazard Area (SFHA),
the impact adjustment ratio is 1.0.
b. Under Option 2, if the plan does not cover all buildings in the SFHA, a default impact
adjustment ratio of 0.25 may be used.
c. Under Option 3, if the plan does not cover all buildings in the SFHA, the impact adjustment
ratios reflect the proportion of the buildings in the SFHA covered by the plan.
633
Credit Calculation. The credit points for DFP are multiplied by the impact adjustment
ratios and added to SDS.
634
Credit Documentation.
The community must have the following available to verify implementation of this activity.
a. [Required only if applying for DFP credit under Section 631.b.1] The portions of the
emergency plan or other documentation that show that it has dam failure inundation areas,
flood elevations, and estimated arrival times, an annual report from the dam operator, annual
exercises; and monthly communications checks.
.
b. [Required only if applying for credit under Section 631.b.2] The portions of the community’s
emergency plan that detail at least three methods of disseminating a dam failure warning.
c. [Required only if the community is applying for credit under Section 631.b.3]
1. The portions of the community’s emergency plan that indicate evacuation routes and
procedures for notifying and evacuating critical facilities; and
2. Documentation of the notification of occupants of the dam failure inundation area as
discussed in Section 631.b.3.
d. [If Option 3 was used to determine the impact adjustment ratios] The Impact Adjustment
Map.
The community must submit the following with its annual CRS recertification:
e. [Required only if the community applying for credit under Section 631.b.1] Documentation
of the monthly communications checks between dam operators and local officials and a
description of the dam failure exercise, drill, or response to an emergency or disaster during
the previous year.

Dam Safety
630 DAM SAFETY
Credit is provided to the community based on its state’s dam safety program.
Background: A state dam safety program reduces the probability of dam failure and
includes a much larger jurisdiction than the community. Community management of
areas subject to flooding in the event of dam failure and community preparedness for
dam failure further reduce the damage potential.
Dams can create a false sense of security for floodplain residents. Unlike levees, they do not
need flood conditions to fail. They can be breached with little or no warning and send a wall
of water downstream. The combination of high velocity, great depth, and short notice has
proven particularly deadly and destructive. One way to minimize this hazard is to enforce
construction and maintenance standards—usually through a state dam safety program.
There are almost 11,000 dams in the United States that are classified as “high hazard” dams.
A “high hazard” dam is one whose failure would threaten life and property. Of these 11,000
high hazard dams, fewer than 5,000 have emergency action plans (EAPs). All states require
EAPs for new dams, but only a few have statutes that require owners of existing dams to
produce EAPs.
Although the legal definition of a dam for regulatory purposes varies from state to state,
many dams are very small. A dam may be as low as 5 feet, with an impoundment of no more
than 5 acre-feet of water. In many states, highway and railroad embankments may legally be
dams, although they may not be rigorously regulated. This means that, if your community has
one or more high hazard dams upstream, it should not necessarily expect a 100-foot wall of
water to suddenly swamp developed areas. On the other hand, if a dam failure caused even a
25- or 50-year flood with no warning or preparations on a clear day, the results could be
devastating.
Activity Description:
a. The state dam safety element (SDS) provides credit for any community in a state
with a dam safety program that has submitted the necessary documentation of its
program to the Department of Homeland Security’s Federal Emergency
Management Agency (FEMA). Community Rating System (CRS) credit for this
element will be determined for each state based upon the elements of its dam
safety program.
Two conditions are prerequisites for credit under this element:
1. If a state does not receive credit for this element, no community within that state
is eligible for credit for this element.

Edition: July 2007
634 Credit Documentation
There is no documentation required for the community to receive credit points based
on the state’s dam safety program. The credit points will automatically be added to the
community’s credit, provided the state verifies community compliance with the state’s
program.
The community must provide the following documentation:
a. [Required only if the community is applying for credit under Section 631.b.1] The
portions of the community’s emergency plan or other documentation that show the dam
failure inundation areas, flood elevations, and estimated arrival times, an annual report
from the dam operator, annual exercises, and monthly communications checks.
b. [Required only if the community is applying for credit under Section 631.b.2] The
portions of the community’s emergency plan that detail at least three methods of
disseminating a dam failure warning.
c. [Required only if the community is applying for credit under Section 631.b.3]
1. The portions of the community’s emergency plan that indicate evacuation routes
and procedures for notifying and evacuating critical facilities; and
2. A copy of the materials that notify occupants of the dam failure inundation area
as discussed in Section 631.b.3. The materials must be distributed each year and must
reach at least 90% of the properties in the dam failure inundation area. An outreach
project to the community or to floodplain properties credited under Activity 330
(Outreach Projects) may qualify for this credit provided that it explains the dam failure
hazard, the area affected, evacuation routes, and flood safety topics appropriate to the
hazard.
d. [Required only if the community determines the impact adjustment ratios using
Option 3 (633.c)] The Impact Adjustment Map with the appropriate acronyms marked.
Documentation showing how the impact adjustment ratio was determined.
The community must submit the following documentation with its annual CRS
recertification (see Section 214):
e. [Required only if the community is applying for credit under Section 631.b.1]
Documentation of the monthly communications checks between the dam operators
and local emergency officials and a description of the exercise or drill of the dam
failure emergency plan or the response to an actual emergency or disaster
conducted during the previous year. The description must include a list of who
participated and any lessons learned from the exercise, drill, emergency, or
disaster.

INSTRUCTIONS
The following activity worksheets are to facilitate calculations of Community Rating System
(CRS) credit points. They are not used for a community’s initial application to the CRS. INITIAL
APPLICATIONS FOR THE CRS ARE SUBMITTED USING THE WORKSHEET PAGES IN THE CRS
APPLICATION.
These activity worksheets are for internal use by the community, for submittal of modifications,
and for use by the ISO/CRS Specialist during verification and cycle verification of a
community’s program.
These worksheets are designed to be used in conjunction with the CRS Coordinator’s Manual.
Each section of the worksheets corresponds to a section in the Coordinator’s Manual. If a
section is missing from the worksheets, it is because the Coordinator’s Manual shows that no
data or calculations are required for that section.
It is recommended that these worksheets be photocopied before they are used.
When used for submitting a modification, the Credit Points, Credit Calculation, and Credit
Documentation parts of the worksheets should be completed for each activity for which credit is
requested. Fill in the blanks with the value for each variable. DO NOT COMPLETE THE
VERIFICATION SECTIONS . That is done by the ISO/CRS Specialist during the verification or cycle
verification visit.
Each worksheet has a Credit Documentation section. Check the blanks to denote that all of the
required documentation is available. In some cases, the documentation must be provided with
the modification. In others, checking the appropriate spaces confirms that you will provide the
documentation when needed. Please consult the CRS Coordinator’s Manual if you have
questions about which documentation is to be provided with the request for a modification.
ATTACH
THE REQUIRED DOCUMENTATION FOR AN ACTIVITY TO THE WORKSHEET FOR THAT
ACTIVITY .
If the documentation is ordinance language, attach only the necessary page(s) from
the ordinance.
M ARK THE MARGINS OF THE DOCUMENTATION WITH THE ACRONYM for the element so the
ISO/CRS Specialist can identify the basis for the credit. If the document is a certification, it
must have an original signature (and seal if required).
Not included in this document are the activity worksheets needed for obtaining credit for
management of special flood-related hazards, such as uncertain flow paths, closed basin lakes,
ice jams, land subsidence, coastal dunes and beaches, mudflows, coastal erosion, and tsunamis.
Those worksheets can be found in the appropriate publications listed in Appendix E of the CRS
Coordinator’s Manual and in Appendix B of the CRS Application.
Two other worksheets are not part of this document: AW-214 (Recertification) and AW-501
(Repetitive Loss List). When needed, these two worksheets are generated separately by the
Department of Homeland Security’s Federal Emergency Management Agency (FEMA) and
provided to the community.

4. I hereby certify that to the best of my knowledge and belief, we are maintaining in force all flood
insurance policies that have been required of us as a condition of federal financial assistance for
insurable buildings owned by us and located in the Special Flood Hazard Area shown on our
Flood Insurance Rate Map. I further understand that disaster assistance for flooded public
buildings in the Special Flood Hazard Area will be reduced by the amount of flood insurance
available from the National Flood Insurance Program for the buildings, even if we do not have a
policy.

similar regulations. The margin next to where this appears in the ordinance must be
marked “SZ,” OR .
Provide written assurance from a county, regional, or state agency that similar
standards are in effect in the upstream communities.
3. DS: The ordinance language that includes the design storm(s) used by the community for
stormwater management regulation. This is the recurrence interval for the storm(s) that is/are
regulated to prevent increased runoff due to development. If credit is based on language that does
not include storm recurrence intervals, the community must provide an estimate of the recurrence
intervals. The margin next to where this appears in the ordinance must be marked “DS.”
Ordinance language from upstream communities within the watershed with the same or
similar regulations. The margin next to where this appears in the ordinance must be
marked “DS.” OR

procedure for inspections and records of actual inspections and maintenance. This
documentation is similar to, and may be combined with, documentation for channel
debris removal (CDR) in Activity 540.
5. Impact adjustment. E ITHER
If the community uses Option 1, it must document that all of the watershed that affects
the community is regulated to the same standard. This is true if there is a regional
stormwater management standard applied by all upstream communities, or if the
community is entirely on an island, and no other communities on the island drain into
the community, or if the community’s upstream boundaries exactly match the
watershed boundaries. Provide an Impact Adjustment Map that shows the area
regulated by the community (usually the community’s boundaries) (marked “aSMR”)
and the boundaries of the watershed that affects the community (marked “aW”). aSMR
and aW must be equal. OR
If the community uses Option 2, rSMR = 0.25 and no documentation is required. OR
If the community uses Option 3, it must provide an Impact Adjustment Map. Provide an
Impact Adjustment Map that shows the area regulated by the community (usually the
community’s boundaries) (marked “aSMR”) and the boundaries of the watershed that
affects the community (marked “aW”). If areas within the upstream watershed are
regulated by other communities, their boundaries must also be marked.
b. Watershed Master Plan (WMP):

___ The community has reviewed the repetitive loss list dated ___________, 200___, and
___
Attached are updated Repetitive Loss Update Worksheets, AW-501. OR
___
There are no changes to FEMA’s repetitive loss list.
As the current CRS Coordinator for ______________________[community name], I have

properties. For each property in need of update, I have attached an AW-501 that reflects the
current and accurate address, the correct NFIP community identification number, and all known
mitigation actions with the primary source of funding noted. In addition, to the best of my
knowledge and belief, any AW-501 not updated and submitted as part of this application has been
checked and is not in need of update at this time.
Signature: ___________________________________________ (Community CRS Coordinator)
502 Repetitive Loss Category:
After updating, the number of properties counted for CRS purposes is:___ This community is a:
___ Category A community because it has removed all properties from being counted as
repetitive loss properties for CRS purposes.

612 Impact Adjustment:
Credit points for each element are adjusted to reflect the extent of coverage of the flood warning
program. Local governments should describe the impact of their flood warning program using one
of the following options.
Option 1:
The flood threat recognition system, the warning dissemination system, and the flood response
tasks COVER THE ENTIRE Special Flood Hazard Area (SFHA). ____ Yes _____No [Remember,
the area credited by the flood warning program is the area where the warning program can
forecast specific flood conditions in the future. This includes areas where flood elevations and
arrival times can be forecast. It does not include areas where the National Weather Service or
others can only predict flooding “along streams and low areas.”]
Option 2:
If the flood threat recognition system, the warning dissemination system, and the flood response
tasks COVER LESS THAN THE ENTIRE SFHA, the local government may use a default value of 0.25 for
rFTR, rEWD, and rORE. ______ Yes _______ No
Option 3:
Where local flood warning programs COVER MORE THAN 25% OF THE STRUCTURES, BUT NOT ALL OF
in the SFHA, the community may use Option 3. Using this option the impact
adjustment ratios for FTR, EWD, and ORE are computed by dividing the number of buildings
affected by each element by the total number of buildings in the SFHA (bSF).
THE STRUCTURES
rFTR=bFTR
