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. Once damage passes a certain level, the city's substantial-improvement rule can alter what the rebuild is allowed to include.

Citywide mapping cannot establish your parcel's zone, your policy's terms, or how far moisture has traveled through the structure. Verify the designated zone with the city, what the policy actually covers with your insurer, and how far moisture has traveled using instruments rather than eyes.
