Fema map flood zone4/9/2024 The lowest point on the lot(s) must be at or above the BFE.īoth the lowest point on the lot and the lowest floor of the structure must be at or above the one-percent-annual-chance flood elevation. The participating community must also determine that the land and any existing or proposed structures to be removed from the SFHA are "reasonably safe from flooding." The lowest adjacent grade of the structure be at or above the BFE. The lowest adjacent grade (the lowest ground touching the structure) be at or above the base flood elevation (BFE). Requests Involving One or More Structures Requirements Letter of Map Revision-Based on Fill ( LOMR-F) The community needs to ensure that permits are obtained per requirement under Section 60.3(a)(2) of FEMA's regulations. See all NFIP regulations and guidance documents.Įndangered Species Act compliance is required independently of FEMA's process. The National Flood Insurance Program (NFIP) regulates the requirements for the Letter Of Map Amendment (LOMA) process and the Letter of Map Revision-Based on Fill (LOMR-F) process. Online Letter of Map Change (LOMC) Training Tutorial Upon receiving a complete application forms package through mailing a paper form or through the Online LOMC application, FEMA will normally complete its review and issue its determination in 60 days. In most cases, the applicant will need to hire a Licensed Land Surveyor or Registered Professional Engineer to prepare an Elevation Certificate for the property. Through these processes, an individual who owns, rents or leases property may submit certain mapping and survey information to FEMA and request that FEMA issue a document that officially removes a property and/or structure from the SFHA. These processes are referred to as the Letter of Map Amendment (LOMA) process and the Letter of Map Revision-Based on Fill (LOMR-F) process. Recognizing that these situations do occur, FEMA established administrative procedures to change the designation for these properties on the FIRM. Requesting a Change to the Flood Insurance Rate Map Because of the limited extent of the elevated area and the limitations of the map scale, it may not have been possible for FEMA to show this area as being outside the SFHA and so these areas have been incorrectly included in the SFHA on the FIRM. This construction may have taken place during the time the engineering study was being performed or subsequent to that study. Such cases are referred to as "inadvertent inclusions."įor other small areas, earthen fill may have been placed during construction, thereby elevating a small area within the SFHA to an elevation that is at or above the BFE. This elevation is most commonly referred to as the Base Flood Elevation (BFE). However, because of limitations of scale or topographic definition of the source maps used to prepare a FIRM, small areas may be inadvertently shown within a Special Flood Hazard Area (SFHA) even though the property is on natural ground and is at or above the elevation of the one-percent-annual-chance flood. FEMA uses the most accurate flood hazard information available and applies rigorous standards in developing Flood Insurance Rate Maps (FIRMs).
