Hazards
Ratings come from FEMA's National Risk Index (v1.20, planning-level) and the public federal and state maps named on each row, not a private climate model. FEMA rates each census tract from expected annual losses, community resilience and social vulnerability, for planning; it is not an assessment of this parcel. No rating: FEMA computed no expected annual loss for this census tract; not a statement about this parcel.
Recorded flood claims
Insured buildings near this parcel, not the parcel itself. FEMA counts claims on buildings with NFIP flood insurance, so land that never had an insured building has no claims to count. The count is the parcel's census block group when it has 10 or more, else its tract's; a count under 10 prints as "Fewer than 10". Source: OpenFEMA NFIP Redacted Claims v3.
Neighborhood (Census)
± is the Census 90% margin of error; a figure comes from the larger census tract when the block group's sample is too small.
Parcel outline
The outline and its edge lengths are measured on the parcel map the map draws; the aerial loads from the public imagery named under it.
