National Flood Insurance Program 1- Guide future development away from flood hazard areas; 2- Require that new and substantially improved buildings be constructed to resist flood damage; 3- Provide homeowners with financial assistance after floods, especially after smaller floods that do not warrant federal disaster aid, and; 4- Transfer some of the costs of flood losses from the taxpayers to the property owners.
