FEMA Adds Buildings to 100-Year Flood Risk Maps, Plans to Audit Flood-Zone Properties

When the Federal Emergency Management Agency (FEMA) updated its flood-zone maps for New York City, it covered 84,596 structures in the five boroughs, up from 23,885 in the 2010 maps, according to a recent report by New York City Comptroller Scott Stringer. These newly analyzed flood insurance rate maps (FIRMs), which were proposed last year and are awaiting federal approval, could increase flood-insurance rates by as much as 18 percent per year for similar levels of coverage, the report says.
