What Glasgow faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
River and rain flooding
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.
What’s behind Glasgow’s grade
River and rain flooding is 87% of the building damage FEMA expects in Glasgow, and Glasgow’s rate of river and rain flooding damage is higher than 69% of U.S. census tracts.
B− #27 of 37 in Delaware; lower expected damage per building than 53% of U.S. towns (21,298).
Glasgow’s residents live in 5 census tracts; FEMA’s figures are combined by where they live.
The typical Delaware town has lower expected damage than 65% of U.S. towns; within the state, Glasgow has more expected damage per building than 72% of Delaware towns.
