MAP AMENDMENTS The accuracy of the floodplain boundaries shown on NFIP maps is limited by the scales at which the maps are prepared and by the topographic data available to prepare them, As a result, map users will occasionally find it difficult to determine whether a speCific structure or parcel of land is within the SFHA Also, small areas of high ground may be included in the SFHA because they are too smali to be shown to scale, When this happens, structures or parcels of land may be inadver- tently included in the SFHA when the map is prepared, The inclusion of land areas will also pose a problem for persons who propose to build new structures in them, Because the Federal requirement for the purchase of flood insurance and the Federal and local regulations governing construction in the SFHA are important to persons who own or plan to build structures, FEMA has developed the Map Amendment process, Under this process property owners may request that FEMA determine whether speCific structures or legally described parcels of undeveloped iand are or would be in the SFHA and, if necessary, amend the effective map accordingly, A. Background Under the Map Amendment process, FEMA will make final and con- ditional determinations for single or multiple structures on one or more lots, or for parcels of undeveloped land that can be legally described, These determinations will be made by FEMA using the best available data (usually the effective NFl P map) and information provided by the requestor concerning the existing or proposed locations and elevations of structures or the locations and existing elevations of legally des- cribed parcels of undeveloped land, The Map Amendment process is applicable only to requeats for determinations concerning structures and legally described parcels of developed land based on topographic conditions that existed before the effective date of the first NFIP map that showed the structure or parcel of land to be within the SFHA, This includes natural ground as well as any fill placed prior to the date of that map, Structures and parcels of land may be determined to be . Out of the SFHA as shown on the effective FEMA map, No amend, ment to the map is necessary, . Out of the SFHA because the structure or parcel of land is above the BFE (inadvertent inclusion), The effective map is amended to exclude the existing structure from the SFHA. . In the SFHA because the structure or parcel of land is below the BFE. If necessary, the effective map will be amended to include the structure in the SFHA. Only the effective NFIP map may be amended under the Map Amendment process, All final determinations and Amendments made by FEMA are described in LOMA's in the previous section, Conditional determinations for proposed structures are described in Conditional LOMA's in the previous section, B. How To Request an Amendment Any owner or lessee of property may request that a determination be made concerning a structure of parcel of land and that, if necessary, the effective NFIP map be amended accordingly, Because these requests concern structures and parcels of land that were inadvertently included 29
