Although revisions may be requested to change any of the information presented on the NFIP maps, FEMA generally will not revise an effective map unless the changes involve modifications to Special Flood Hazard Areas (one percent annual chance floodplains or flood elevations). FEMA relies heavily on communities to provide notification of changing flood hazard information and to submit the technical support data needed to reflect the updated flood hazards on the NFIP maps. The flood hazard maps must present flood risk information that is correct and up to date to ensure that they provide a sound basis for floodplain management and insurance rating. As a result, FEMA prioritizes study and restudy needs based on a cost-benefit approach whereby the highest priority is given to studies where development is greatest and where the maps are most outdated. Because of funding constraints, however, FEMA can study or restudy only a limited number of communities each year. for the creation, as well as the revision, of community flood hazard maps.
