Real, disclosed coastal-storm exposure

Kennebunk's beach frontage (Kennebunk Beach, Gooch's Beach, Mother's Beach) carries a real, direct coastal-storm and flood-surge exposure consistent with Maine's broader coastal risk profile.

A real, separate, dated riverine flood risk

The Intervale neighborhood along the Mousam River has a real, documented flood history dating to 1953, with stormwater repeatedly overflowing the riverbanks and flooding approximately 18 houses during heavy rains.

A genuinely favorable statewide insurance backdrop

Maine's own statewide homeowners-insurance average ran approximately $1,335-$1,433/year, though Kennebunk properties in either flood-exposed area likely carry a real premium above that statewide figure.
