Elevation certificates are used to identify the elevations that new buildings and substantial improvements will be placed that are located within special flood hazard areas (SFHAs) so that flood hazards are reduced or eliminated. The elevation certificate may be required for obtaining flood insurance, by property owners whose property is within or partially within a known flood hazard area.
Letters of map amendment are used to correct the flood hazard map to reflect the actual elevation of the area being corrected and potentially removing that area from the flood hazard designation previously established.
