What stands out about Corning’s natural hazards
From FEMA’s model and FEMA’s records, below.
What Corning 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 Corning’s grade
River and rain flooding is 94% of the building damage FEMA expects in Corning, and Corning’s rate of river and rain flooding damage is higher than 51% of U.S. census tracts.
