Part of this lot lies in the AE flood zone

Compiled from published federal, state and municipal records on 2026-09-10. Each finding names its source and links to the agency that holds the underlying file. FEMA flood zones are regulatory map boundaries, not forecasts — flooding occurs outside them. A DEC spill record is a report filed at an address, not a determination about the building; a closed case means the agency closed its file. This section is not a risk score, an all-clear, or insurance, legal, appraisal, or real-estate advice. Confirm anything material with FEMA, DEC, your insurer, counsel, and the municipality before you act. See also Terms of Use.
