In May 2010, historic flooding (a greater than 1,000-year rainfall event) occurred in Benton County adversely affecting the City of Camden’s 2,500-LF high-flow channel that protects the wastewater treatment plant lagoon’s levees from flood impacts. The channel had performed its function and protected the lagoon, but it was affected with significant sediment deposition and scouring. In accordance with the City’s longstanding agreement with state and federal agencies to maintain the channel, it was imperative to repair it as soon as possible to protect the lagoon against future floods.

Utilizing federal funding, the City contracted with CIA Engineers to design, permit, and implement the emergency repairs. Working with the Natural Resources Conservation Service (NCRS)and the West Tennessee River Basin Authority, CIA Engineers developed design documents to remove sediment deposition from the high-flow channel, remove debris from Cypress Creek, re-grade the channel, replace the concrete low-water creek crossings, replace rip-rap, stabilize damaged areas, and coordinate state and federal permits such as the Stormwater Construction Permit and the Aquatic Resource Alteration Permit, and compile the associated Stormwater Pollution Prevention Plan. In addition, CIA Engineers provided construction administration, coordination, and inspection.
