FEMA expects about as much hazard damage per building in Greenwich as in the typical U.S. town, mostly from river and rain flooding

On FEMA’s National Risk Index, Greenwich gets a B for hazard risk: lower expected damage per building than 57% of U.S. towns, #477 of 758 in New York. Most of that expected damage is river and rain flooding (89%). Flood insurance has paid 1 claim here since 1981.

People, not buildings.Counting harm to people as well as buildings, FEMA’s model puts cold waves at 8% of Greenwich’s expected losses. Cold waves do little damage to buildings (0.0%), so they aren’t part of the grade.

Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.

Flood risk changes street by street. Check a specific address on FEMA’s flood map, and ask about flood insurance before you buy.
