The excavation quantity is approximately 350,000 cubic yards (CY) of which approximately 35,000 CY can be placed on-site. There are 4 concrete flood control structures, 2 - 2 pipe outlet banks, headwalls, rip-rap, wire-tied rip-rap, maintenance access roads, guardrail , handrail, other safety measures, fencing and hydroseeding. Currently Ardurra Engineering is designing an expansion of the Copeland Detention Basin facility that would reduce flows to the highway so the depth of flows overtopping the highway will be significantly reduced. Maintaining good community relations during construction in these neighborhoods is critical to success.
