Flood insurance basics. Most standard homeowners policies do not cover flood damage. NFIP policies are sold through insurance agents and through FEMA's FloodSmart site, which also explains waiting periods (usually 30 days before cover starts). Check your property's flood zone on the FEMA Flood Map Service Center.
