Flood is not part of a homeowners policy; it is bought separately through the NFIP or a private insurer. Alton is an NFIP community, and its current flood map took effect in June 1982. In Hidalgo County, about 1 in 27 homes has an NFIP policy. New NFIP policies usually take 30 days to start.

Renters occupy about 45% of homes in Alton. Landlords generally need a DP-1, DP-2 or DP-3 dwelling policy, and tenants need renters insurance, because the landlord’s policy does not cover a tenant’s belongings.
