How much of each city is in a flood zone?

Every mapped city shaded by the share of its parcels in a high-risk FEMA zone — pale where flooding is the exception, deep where it is the rule. Hover a city for its numbers.

Computed from 1,575,406 mapped parcels against each county's effective FEMA flood layer — not a city-level guess. The share of parcels in a high-risk zone (AE, VE, AH, AO, A) ranges from a few percent to essentially the whole city.

Why the city number is not your number

Flood zones are drawn on FEMA panels that cut through neighborhoods and individual lots. Two houses on the same street can carry different designations and very different insurance bills. Use the city pages above for the local picture, then check the exact parcel.

Flood zone and base flood elevation, zoning, comparable sales and the tax reset a buyer inherits. No sign-up.
