Virginia Code Title 15.2. Counties, Cities and Towns § 15.2-970. Construction of dams, levees, seawalls, etc.; certain proceedings prohibited

A. Any locality may construct a dam, levee, seawall or other structure or device, or perform dredging operations hereinafter referred to as “works,” the purpose of which is to prevent the tidal erosion, flooding or inundation of such locality, or part thereof. The design, construction, performance, maintenance and operation of any of such works is hereby declared to be a proper governmental function for a public purpose.

B. No person, association or political subdivision shall bring any action at law or suit in equity against any locality because of, or arising out of, the design, maintenance, performance, operation or existence of such works but nothing herein shall prevent any such action or suit based upon a written contract. This provision shall not be construed to authorize the taking of private property without just compensation therefor and provided further that the tidal erosion, flooding or inundation of any lands of any other person by the construction of a dam or levee to impound or control fresh water shall be a taking of such land within the meaning of the foregoing provision.
