When floodplains are altered, the ability of floodplains to absorb floodwaters and reduce risk from a flood is diminished. Development within a floodplain can make flooding and flood damage more severe and extensive. Nearly all municipalities in New York have flood damage prevention laws which are a critical component of reducing municipal risk from damaging floods, and a critical requirement that must be met to qualify municipalities for the National Flood Insurance Program.
Laws that govern the use, siting, design, construction, and maintenance practices in floodplain areas can complement flood damage prevention laws and help manage floodplain development and to limit damage from flooding.
