Floodplain management regulation.
Statewide floodplain management regulation shall be exercised through: (1) Local governments' administration of the national flood insurance program regulation requirements, (2) the establishment of minimum state requirements for floodplain management that equal the minimum federal requirements for the national flood insurance program, and (3) the issuance of regulatory orders. This regulation shall be exercised over the planning, construction, operation and maintenance of any works, structures and improvements, private or public, which might, if improperly planned, constructed, operated and maintained, adversely influence the regimen of a stream or body of water or might adversely affect the security of life, health and property against damage by flood water.
