The U.S. Army Corps of Engineers, in partnership with the District, constructed the ACDC in the 1980s. The District owns, operates and maintains the channel.
Storm drain inlet pipes have begun to exhibit cracking along vertical-walled segments of the ACDC. This cracking, if unaddressed, would allow storm water flows to enter the wall backfill to saturate and further consolidate, potentially jeopardizing the integrity of the 20-foot vertical wall.
This project will address this deficiency and will involve engineered storm drain improvements to extend the life of the channel wall. The project is phased to allow for the exploration of multiple solutions.
Construction is complete. The repair project began in May, 2009. The first set of repairs between 7th Avenue and 47th Avenue is complete. The second set of repairs between 24th Street and 32nd Street is complete. The third set of repairs between Central Avenue and 24th Street and along the Cave Creek branch is complete. Three additional sets of repair sites at twenty-seven locations and flap gate repairs were identified, authorized and completed.
