PURPOSE OF THE DRY FLOODPROOFING CERTIFICATE FOR NON-RESIDENTIAL STRUCTURES
Under the National Flood Insurance Program (NFIP), the dry floodproofing of non-residential buildings may be permitted as an
alternative to elevating to or above the Base Flood Elevation (BFE) or for certain flood zones, the natural Highest Adjacent Grade
(HAG). A dry floodproofing design certification is required for non-residential structures that are dry floodproofed and the dry
floodproofed non-residential portions of mixed-use buildings. This form is to be used for that certification. FEMA Form 206FY-21-122 NFIP Residential Basement Floodproofing Certificate is required for the residential portions of mixed-use buildings.
A dry floodproofed building is a building that has been designed and constructed to be watertight (substantially impermeable to
floodwaters) below the BFE and with structural components having the capability of resisting hydrostatic and hydrodynamic loads
and effects of buoyancy. Before a dry floodproofed building is designed, numerous planning considerations, including flood warning
time, uses of the building, mode of entry to and exit from the building and the site in general, floodwater velocities, flood depths,
debris impact potential, flood frequency, and any other State and local requirements must be addressed to ensure that dry
floodproofing will be a viable floodplain management measure.
The minimum NFIP requirement is to dry floodproof a building to the BFE. However, to be in compliance with the requirements of
American Society of Civil Engineers (ASCE) 24, Flood Resistant Design and Construction, one foot is subtracted from the dry
floodproofed elevation. Therefore, a building must be dry floodproofed to one foot above the BFE to be considered for floodproofing
credit. For B, C, or X flood zones, the building's dry floodproofed design elevation must be at least two feet above the natural HAG to
be considered for floodproofing credit.
Additional guidance can be found in FEMA Publication 936, Floodproofing Non-Residential Buildings (2013), and NFIP Technical
Bulletin 3, Requirements for the Design and Certification of Dry Floodproofed Non-Residential and Mixed-Use Buildings (2021),
available on FEMA's Building Science Resource Library website at www.fema.gov/ar/emergency-managers/risk-management/
building-science/publications.

Copy all pages of this Dry Floodproofing Certificate and all attachments for 1) community official, 2) insurance agent/company, and
3) building owner. The dry floodproofing of non-residential buildings and the non-residential portions of mixed-use buildings may be
permitted as an alternative BFE); however, a dry floodproofing design certification is required. This form is to be used for that
certification. Dry floodproofing of a residential building does not alter a community’s floodplain management elevation requirements
or affect the insurance rating unless the community has been issued an exception by FEMA to allow dry floodproofed residential
basements. The permitting of a dry floodproofed residential basement requires a separate certification specifying that the design
complies with the local floodplain management ordinance.

INSTRUCTIONS FOR COMPLETING THE DRY FLOODPROOFING CERTIFICATE
FOR NON-RESIDENTIAL STRUCTURES
To receive credit for dry floodproofing, a completed Dry Floodproofing Certificate for Non-Residential Structures is required for nonresidential buildings and the non-residential portions of mixed-use buildings in the Regular Program communities, located in all flood
zones, including Zone X.
PROPERTY INFORMATION
This section identifies the building, its location, and its owner. Enter the name(s) of the building owner(s), the building's complete street
address, and the lot and block numbers. If the building's address is different from the owner's address, enter the address of the building
being certified. If the address is a rural route or a Post Office box number, enter the lot and block numbers, the tax parcel number, the
legal description, or an abbreviated location description based on distance and direction from a fixed point of reference.
A map may be attached to this certificate to show the location of the building on the property. A tax map, FIRM, or detailed community
map is appropriate. If no map is available, provide a sketch of the property location, and the location of the building on the property.
Include appropriate landmarks such as nearby roads, intersections, and bodies of water. For building use, indicate whether the building
is residential, non-residential, an addition to an existing residential or non-residential building, an accessory building (e.g., garage), or
other type of structure. Use the Comments area of the appropriate section if needed or attach additional comments.

DRAFT

Provide latitude and longitude coordinates for the center of the front of the building. Use either decimal degrees (e.g., 39.504322°,
−110.758522°) or degrees, minutes, seconds (e.g., 39° 30' 15.52", −110° 45' 30.72") format. If decimal degrees are used, provide
coordinates to at least 6 decimal places or better. When using degrees, minutes, seconds, provide seconds to at least 2 decimal
places or better. Provide the datum of the latitude and longitude coordinates (FEMA prefers the use of NAD 1983). Indicate the
method or source used to determine the latitude and longitude in the Comments area.
SECTION I – FLOOD INSURANCE RATE MAP (FIRM) INFORMATION

Complete the Dry Floodproofing Certificate using the Flood Insurance Study (FIS) and FIRM in effect at the time of the certification.
The information for Section I is obtained by reviewing the FIS and the FIRM panel that includes the building's location. Information
Letter of Map Amendment (LOMA), Letter of Map Revision (LOMR), or LOMR Based on Fill (LOMR-F) has been issued by FEMA,
about the current FIS and FIRM is available from FEMA by visiting msc.fema.gov or contacting the local floodplain administrator. If a
please provide the letter date and case number in the Comments area, as appropriate.
For a building in an area that was mapped in one community but is now in another community due to annexation or dissolution, enter
the community name and 6-digit number of the community in which the building is now located in the name of the county or new
county, if necessary; and the FIRM index date for the community the building is now located in. Enter information from the actual
FIRM panel that shows the building location, even if it is the FIRM for the previous jurisdiction. If the map in effect at the time of the
building's construction was other than the current FIRM, and you have the past map information pertaining to the building, provide
the information in the Comments area.
Note: Indicate in the Comments Section, if using information based on best available data, such as base-level engineering or
advisory flood hazard data (contact the local floodplain administrator to confirm).
NFIP Community Name & Community Identification Number. Enter the complete name of the community in which the building is
located, and the associated 6-digit Community Identification Number. For a newly incorporated community, use the name and 6-digit
number of the new community. Under the NFIP, a "community" is any State or area or political subdivision thereof, or any Indian
tribe or authorized native organization which has authority to adopt and enforce floodplain management regulations for the areas
within its jurisdiction. To determine the current community number, see the NFIP Community Status Book, available on FEMA's web
site at www.fema.gov/national-flood-insurance-program-community-status-book.
County Name. Enter the name of the county or counties in which the community is located. For an unincorporated area of a county,
enter the county name and "unincorporated area." For an independent city, enter "independent city."
State. Enter the 2-letter state abbreviation (for example, VA, TX, CA).
Map/Panel Number and Suffix. Enter the 10-character "Map Number" or "Community Panel Number" shown on the FIRM where
the building or manufactured (mobile) home is located. For maps in a county-wide format, the sixth character of the "Map Number" is
the letter "C" followed by a 4-digit map number. For maps not in a county-wide format, enter the "Community Panel Number" shown
on the FIRM.

FEMA Form FF-206-FY-22-153 (formerly 086-0-34) (3/22)

Page 7 of 8

FIRM Index Date. Enter the effective date or the map revised date shown on the FIRM Index.
FIRM Panel Effective/Revised Date. Enter the effective date shown on the current FIRM panel. The current FIRM panel effective
date can be determined by visiting msc.fema.gov or contacting the local floodplain administrator. In addition, if the area where the
building is located was revised by a LOMR, include the LOMR effective date.
Flood Zone(s). Enter the flood zone, or flood zones, in which the building is located. All flood zones containing the letter "A" or "V"
are considered Special Flood Hazard Areas. The flood zones are A, AE, A1–A30, V, VE, V1–V30, AH, AO, AR, AR/A, AR/AE, AR/
A1–A30, AR/AH, AR/AO. Each flood zone is defined in the legend of the FIRM panel on which it appears.
BFE(s). Using the appropriate Flood Insurance Study (FIS) Profile, FIS Data Table (e.g., Transect, Floodway, etc.), or FIRM panel,
locate the property and enter the BFE (or base flood depth) of the building site to the nearest tenth of a foot (nearest tenth of a
meter, in Puerto Rico). If the building is located in more than one flood zone, list all appropriate BFEs.
BFEs are shown in the FIS or on a FIRM for Zones A1–A30, AE, AH, V1–V30, VE, AR, AR/A, AR/AE, AR/A1–A30, AR/AH, and AR/
AO; flood depth numbers are shown for Zone AO. Use the AR BFE if the building is located in any of Zones AR/A, AR/AE, AR/A1–
A30, AR/AH, or AR/AO.
In unnumbered A or V zones where BFEs are not provided in the FIS or on the FIRM, BFEs may be available from another source.
For example, the community may have established BFEs or obtained BFE data from other sources (e.g., Base Level Engineering)
for the building site. For subdivisions and other developments of more than 50 lots or 5 acres in Zone A, establishment of BFEs is
required per Floodplain Management requirements 44 CFR 60.3(b)(3). If a BFE is obtained from another source, enter the BFE. The
BFE entered must be based on hydrologic and hydraulic analyses. In an unnumbered A Zone where BFEs are not obtained from
another source, enter N/A.

DRAFT

For areas in which BFEs have not been established, designers can refer to FEMA 265 Zone A Manual: Managing Floodplain
Development in Approximate Zone A Areas (FEMA 1995), https://www.fema.gov/sites/default/files/documents/fema_approx-zone-aguide.pdf?id=2215. This guide provides information on obtaining and developing BFEs.
Source of BFE. Indicate the source of the BFE or flood depth that you entered. If the BFE is from a source other than FIS Profile,
FIRM, or community, include the name of the study, the agency or company that produced it, and the date when the study was
completed. Visit msc.fema.gov or contact the local floodplain administrator to access the current FIS and FIRM.
Elevation Datum. Indicate the elevation datum to which the elevations on the applicable FIRM are referenced as shown on the map
legend. The vertical datum is shown in the Map Legend and/or the Notes to Users on the FIRM.
Limit of Moderate Wave Action (LiMWA). Indicate if a LiMWA is shown on the FIRM and the location of the building in relation to
the LiMWA.
Floodway. Indicate if building is in a floodway and if applicable, the velocity in the area of the building. See FEMA P-936,
Floodproofing Nonresidential Buildings for more information on determining the velocity.
Alluvial Fan. Indicate if building is in an alluvial fan and if applicable, the depth and velocity in the area of the building.
SECTION II – DRY FLOODPROOFED DESIGN CERTIFICATION
Section II is to be completed by a Registered Professional Engineer or Architect licensed in the State where the building is located to
certify the design of the dry floodproofing measures as required by 44 CFR 60.3(c)(4).
SECTION III – DRY FLOODPROOFED ELEVATION CERTIFICATION
Section III is to be completed by a Registered Professional Land Surveyor, Engineer, or Architect licensed in the State where the
building is located to provide the surveyed elevations of the as-built construction. To ensure that all required elevations are obtained,
it will be necessary to physically enter the building (for instance, to obtain the elevation of the lowest protected floor). Lowest
protected floor is used as lowest floor is applicable to structures that are not dry floodproofed.
SECTION IV – DRY FLOODPROOFED CONSTRUCTION CERTIFICATION
Section IV is to be completed by a Registered Professional Engineer or Architect licensed in the state where the building is located
to certify the structure, based upon development and/or review of the design, specifications, as-built drawings for construction and
physical inspection, has been designed and constructed in accordance with the accepted standards of practice (ASCE 24-05, ASCE
24-14 or their equivalent) and any alterations also meet those standards and the provisions listed in Section IV.
