LITTLETON, Colo. - Construction crews will begin mobilizing for dam safety maintenance work at Cherry Creek Dam in Arapahoe County, Colo., set to begin in late December.

The U.S. Army Corps of Engineers, Omaha District, recently awarded a contract to Four Star Construction Contractor LLC of Kansas City, Mo., to install a 2,200-foot-long underground outfall pipe system for 14 relief wells that were installed along the downstream toe of the dam in 2012.

The new relief well system is designed to relieve seepage pressure under the dam that could develop during extremely high reservoir elevation levels. The system replaces an existing well system that is more than 65 years old.

The contract also includes relocating 2,500 feet of 6-foot-high chain-link fence, 30 feet to the north of the existing fence along Interstate 225.

All work will be performed at the downstream (north) toe of Cherry Creek Dam, immediately south of Interstate 225.  Crews will begin placing construction trailers and stormwater pollution prevention measures this week. Construction will likely begin in late December and will continue through spring 2015.
