Flood status can decide whether you are covered
Standard homeowner policies exclude flood, which is insured separately. Surrounded by water on three sides, the distinction between a plumbing failure and surge or storm intrusion is therefore decisive rather than academic. Where damage is extensive, the substantial-improvement threshold administered by the city can also change what the repair is permitted to involve.

Document the source before anything is moved
Citywide mapping cannot establish your parcel's zone, your policy's terms, or how far moisture has travelled through the structure. Confirm the zone with the city, coverage with your insurer, and extent with moisture readings rather than appearance.
