Which policy pays for coastal inundation
Water driven inland by a storm — surge, wave wash or tsunami — is flood under the standard definitions used in Texas. It is excluded from homeowner policies without exception, and it is claimed under the NFIP or a private flood policy. Wind damage from the same storm is claimed separately.
In a severe coastal event, the majority of the physical loss is usually water, but the wind component is rarely nil, and it is often what determines whether the interior of a partially standing structure is paid at all. Both claims need documenting from the same site visit, because a second visit weeks later will not find the evidence still there.
