What documentation meets NFIP requirements for recording the elevation of the lowest floor?

To satisfy NFIP (National Flood Insurance Program) requirements for documenting the elevation of the lowest floor of a structure, a surveyor's or engineer's record is the appropriate choice. This documentation is critical because it provides precise and professional measurements of the elevation, ensuring compliance with floodplain management standards. The accuracy of these records is essential for determining the building's flood risk and eligibility for insurance.

Using a surveyor or engineer assures that the data collected adheres to specific standards and methodologies recognized by the NFIP. The information recorded must be consistent with the requirements for floodplain management, which emphasizes the importance of reliable and authoritative sources to mitigate flood risks effectively.

Other options, like a building permit, contractor’s report, or city planning document, lack the necessary technical accuracy and formality required to serve as adequate documentation under NFIP stipulations. These documents might provide some information regarding the construction process or local planning, but they do not guarantee the elevation data is measured conformingly or accurately as mandated by NFIP regulations.
