FEMA maps place 338 Hillside Ave 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 338 Hillside Ave has no burnable land within ember reach, so its wildfire risk is not rated.
