You can add New York City to the list of jurisdictions fighting FEMA over redrawn flood zone maps. The Federal Emergency Management Agency (FEMA) has been redrawing Flood Insurance Rate Maps, or FIRMs, for years, releasing new maps in one area after another — and typically triggering some push-back from residents and governments affected by the new flood zone boundaries. In New York, reports the Wall Street Journal, authorities want some of the new flood zones shrunk in spite of the city's recent experience with a disastrous storm surge (see: "New York Disputes FEMA on Flood Risk," by Corinne Ramey).

"FEMA’s map, a preliminary document still subject to final approval and its first significant update since 1983, would expand the number of city residents in the 100-year floodplain by 83% to 400,000. It nearly doubles the number of structures in the zone to 71,500," the Journal reports. "Now, the city is challenging FEMA’s map, saying it overstates the risk of flooding in much of the expanded flood zone, unnecessarily imposing insurance and other costs on homeowners. In late June, the city released the results of its own analysis, conducted by consulting firm Arcadis, which produced a smaller flood zone, one the city says is more reasonable than FEMA’s... The city’s map would remove about 26,000 structures and 170,000 people from FEMA’s floodplain, potentially sparing them a steep increase in insurance costs."
