Map Modernization

Case Study - Staten Island, NY

Mapping:

To correctly delineate the floodplain boundaries on work maps prior to preparing a revised FIRM, FEMA conducted onsite investigations to verify the wetland delineations and performed new analyses for storm sewers within the community that contained flooding discharges. Then FEMA digitized the FIRM and issued a preliminary version of the digital FIRM to the community for review on September 7, 2000. The final digital FIRM became effective on May 21, 2001.
