If you are a homeowner and believe your property is not located in the designated 100-year floodplain [also known as a 1-percent-annual-chance floodplain, or Special Flood Hazard Area (SFHA)], as shown on the effective Flood Insurance Rate Map or Digital Flood Insurance Rate Map for your community and you would like the Federal Emergency Management Agency (FEMA) to make an official determination regarding the location of your property relative to the SFHA, you may request a Letter of Map Amendment (LOMA) or a Letter of Map Revision Based on Fill (LOMR-F).
