FEMA maps place 20 Windsor St in Zone X, an area of minimal flood risk, though there have been 6 flood claims nearby since 1979.

Values are read at the parcel center point; flood claims are located to the census block group, not this parcel; lenders make the official flood determination.

Wildfire

The area around 20 Windsor St has no burnable land within ember reach, so its wildfire risk is not rated.

Values cover an area roughly 900 ft across, not the parcel itself; insurers use their own ratings.
