How to read this map
High-risk floodplain is the share of a neighborhood’s parcels that fall in a FEMA Special Flood Hazard Area — the A, AE, AH, AO, V and VE zones. This is the regulatory 1%-annual-chance (“100-year”) floodplain, where flood insurance is mandatory if you carry a federally-backed mortgage. A parcel counts if any part of it overlaps such a zone.
Any flood zone widens the lens to every mapped flood hazard, including the 0.2%-annual-chance (“500-year”) shaded-X zone that sits just outside the high-risk line. It’s a “touched by the flood map at all” view — a lower bar than the regulatory floodplain.
