Richmond Local Flood Protection
Richmond Virginia is located at the fall line of the James River in Eastern Virginia. Its specific location makes the area vulnerable to all floods originating in the 6,760 square miles of drainage area upstream. Flooding in the city’s two business districts, Shockoe Valley on the north bank and Manchester in the southside, has resulted in serious and extended business losses to commercial and industrial activities, disruption of rail and highway transportation, and prolonged interruption of public utility operations. The Richmond Floodwall, dedicated on October 21, 1994, protects 750 acres of flood prone land.
