Flood history / Delaware
Delaware
flood claim history.
Across the 16 Delaware ZIP codes with at least 100 paid claims on file, the National Flood Insurance Program has paid $62.9M on 5,075 claims between 1978 and 2026. ZIP 19930 in Sussex County carries the most at 1,414, 27.9% of the state total shown here.
The events driving the most paid claims across these ZIPs are Hurricane Sandy (1,400 claims), Hurricane Floyd (148 claims) and Hurricane Irene (118 claims).
11.6% of the claims here that record a rated flood zone were on properties outside the mapped high-risk area — the zone where flood insurance is optional and most owners go without it.
Claim volume tracks how many properties carried flood insurance as much as how often the water came up. A ZIP with a long insured history will out-file a comparable one where few owners were covered, so read each ZIP's own record rather than ranking them against each other.
