The local flood protection system in Richmond has a total length of 17,327 feet (3.28 miles) and protects 750 acres valued at approximately $153 million. It consists of:
- A partially rip-rapped earthen levee
- A concrete floodwall
- Three overlooks (9th & Semmes, Hull & Mayo Bridge, and 12th & Byrd)
- Six roadway closures
- Six railroad closures
- Four personnel closure locations
- Two combined roadway/railroad closures
- Three pump stations
- Three designated ponding areas
The southside alignment comprises three components
- One earthen levee, approximately 9,000 feet long
- A combination bin wall/levee, approximately 2,000 feet long
- A concrete floodwall, approximately 2,000 feet long
The line of protection extends from just west of the Manchester Bridge, continues along the river's
edge to the west side of Interstate 95, turns south, then west, crossing the CSX Railway mainline tracks,
and tying into high ground at Goodes Street.
Interior runoff from the watershed in excess of the capacity of the pump station during high river
stages will be collected or backed up into the ponding areas. After the river recedes, all ponding
areas will drain by gravity through their respective outlets.
The northern alignment is comprised of one component, concrete floodwall which is approximately 4,500
feet long with height variations from five to 29 feet.
The line of protection extends across the mouth of Shockoe Valley to 12th Street. The wall is designed
to protect those areas located behind it against a flood with an average recurrence interval of 280 years.
The project was dedicated on Oct. 21, 1994, at a cost of $143 million.
