NFIP 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 206-FY-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.
NFIP Elevation Certificate with Instructions
NFIP Elevation Certificate form only
The National Flood Insurance Program (NFIP) Elevation Certificate (EC) (FEMA form 086-0-33) is an administrative tool of the NFIP which is to be used to provide elevation information necessary to ensure compliance with community floodplain management ordinances, to determine the proper insurance premium rate, or support a request for a Letter of Map Amendment (LOMA) or a Letter of Map Amendment based on fill (LOMR-F).
eLOMA
This time saving, user friendly web-based application will provide licensed land surveyors and professional engineers (Licensed Professionals) with a system to submit simple Letter of Map Amendment (LOMA) requests to FEMA. This tool is designed to make a determination based on the information submitted by the Licensed Professional and allow them to generate a determination from FEMA in minutes, provided all pertinent data is on file and the request is not audited.
FEMA P-936 - Floodproofing Non-Residential Buildings
The primary focus of the guidance document is on dry floodproofing technologies for non-residential buildings, but it also includes an overview of other techniques including wet floodproofing and the use of levees and floodwalls. The publication provides information about regulatory requirements, design considerations, and descriptions of floodproofing methods and equipment. Key document features include: 1) Tools to assist the designer or building owner in determining the best floodproofing option for a particular building including a vulnerability checklist, 2) Case studies providing examples of applied floodproofing techniques, 3) Equations for determining flood forces and loads, 4) A summary of results from recent dry floodproofing research and testing for new construction.

FEMA P-348 - Protecting Building Utility Systems from Flood Damage, 2nd Edition (2/17)
The overall objective of this publication is to assist in the construction of buildings with building utility systems that are designed and built so that the buildings can be re-occupied and fully operational as soon as electricity and sewer and water are restored to the neighborhood.
FEMA - 268 Protecting Floodplain Resources - A Guidebook for Communities
This guidebook has been written to introduce officials and citizens at the local level to a basic understanding of natural resources in floodplains and to offer suggestions for creating strategies for wisely managing these important areas. As scientific understanding of ecosystems grows, the importance of conserving and restoring the natural resources and functions of floodplains is increasingly recognized. Historically effective floodplain management was recognized as a necessary task to reduce the loss of life and property. However, floodplain areas are now also recognized as having an intrinsic value of their own as a part of the interconnected ecosystem and an influential role in increasing a community's quality of life
FEMA P-85, Protecting Manufactured Homes from Floods and Other Hazards
FEMA P-85 has been updated to reflect the requirements of the most current codes and standards and to provide a best practices approach in reducing damages from natural hazards. While the original version of FEMA 85 concentrated on flood and wind events, this version also addresses seismic hazards and recommends several multi-hazard resistant foundation designs. Designs are included for wood-framed foundations, conventional concrete and masonry pier foundations, and ground anchors. The ground anchor foundations are based on results from a series of first-of-its-kind saturated and dry soil anchor tests.

FEMA - 511 Reducing Damage from Localized Flooding: A Guide for Communities
This guide is intended to help local offices in cities, towns, villages, and counties in the United States understand what they can do to reduce the damage, disruption, and public and private costs that result from the shallow, localized flooding that occurs within their jurisdictions. This is flooding that all too often escapes the attention received by larger floods or those that are clearly mapped and subject to floodplain development regulations.
FEMA P-1037 - Reducing flood Risk to Residential Buildings that cannot be Elevated
This publication presents a range of flood protection measures available as alternatives to traditional structural elevation for homeowners whose residences meet both of the following conditions:
1 - The residences are existing buildings. This publication is not intended to address construction of new buildings in floodprone areas as these structures should be sufficiently elevated and built in conformance with NFIP and local floodplain management regulations.
2 - The residences are not Substantially Damaged or Substantially Improved, meaning that the buildings have not sustained damage or undergone improvement (i.e., reconstruction, rehabilitation, addition) where the cost of the damage or improvement exceeds 50 percent of the market value of the building before the damage occurred or improvement began. As with new construction, Substantially Damaged or Substantially Improved structures must be re-built in conformance with NFIP and local floodplain management regulations.
