LAKE O'NEIL DREDGING AND RECHARGE PONDS REHABILITATION
Camp Pendleton, CA
Lake O’Neill is fed by Fallbrook Creek. During the rainy season, excess rainwater from the creek is diverted to a series of ponds adjacent to the lake to promote recharge of the aquifer. There are a series of wells that tap into this aquifer to provide water to Marine Corps Base Camp Pendleton in this immediate area.
CJW Construction increased the surface water storage capacity of Lake O’Neill by performing maintenance dredging and rehabilitation of the existing recharge ponds 4, 5, 6 and 7 through excavation. We also performed installation of spillway culverts and the construction of new large levees to form new re-charge ponds 6 and 7.
CJW self-performed all aspects of this project. The scope of work included: clearing and grubbing of ponds 4-7 and setting pond separation; material excavation and re-handle of the excavation material at ponds 4-7; construction of pond 6 and 7; installation of CMP culverts; placement of crushed rock on the levee bench; repair of riprap; dredge and re-handle material from Lake O’Neill to the re-charge ponds. Dredging utilized PVC return line pipe, a booster pump, and a sand separation unit.
CJW gained considerable experience in working within the environmental windows and time constraints placed on our dredging operations by the EPA to protect the biological resources of Camp Pendleton and their habitats. CJW worked hand-in-hand in partnership with the U.S. Army Corps of Engineers to achieve a balance between adequate resource protection and cost-effective dredging. This project required compliance to a strict Storm Water Prevention and Pollution Program, temporary water delivery/recharge, Toad Monitoring, Toad Fence, and a Bird Biologist.
