Future public liabilities related to flood losses can be greatly reduced through proper control of development in floodplains and floodprone areas and maintenance of the existing flood protection infrastructure. Human occupancy of and alteration of floodplains and floodprone areas are threatening public safety, health, and welfare. The cornerstone of any floodplain management strategy is adequate mapping of floodplains and flood prone areas. However, because floodplain mapping is a complex, expensive, and time-consuming endeavor, many areas are not adequately mapped. Many floodplain mapping efforts have occurred in response to specific needs in specific areas, but a coordinated, comprehensive approach has not been undertaken.
Adequate mapping is an important link between landuse and water resources planning.
Protecting the functions of unaltered floodplains is a critical aspect of statewide ecosystem management efforts. As many floodplain areas have been altered, restoring their natural functions is also an important issue. Land acquisition and management through various programs provides a very effective tool for protecting and restoring floodplains. Floodplain management responsibilities are shared among federal, state, regional, and local governments. Inadequate preparation for flood disasters and response have increased property damage and risks to human safety.
