Hansen Dam 15-Acre Recreational Lake

Los Angeles, CA

The Corps of Engineers was directed to plan, design and construct a recreational lake and associated recreational facilities at Hansen Dam. To initiate the planning and design process, NCI prepared the Feature Design Memorandum that presented all engineering design criteria for final design and construction of a 2-acre swimming area for swimming, sunbathing and child’s wading activities; a 13-acre recreational water area for non-powered boating, sailing and fishing uses; and associated recreational facilities for parking, turf/picnic areas, restrooms, lifeguard buildings and stands, launching ramp, footpath and service road. This included engineering criteria for all civil design, hydraulic design, landscape design, and design of associated recreational facilities. Design elements consisted of the lake’s physical layout; lake liner and shoreline treatments; drainage features; and water quality control for the swimming area, filtration pond and recreational area. Water quality control consisted of chlorination, circulation/filtration, aeration and ozonation systems. A comprehensive construction cost estimate and operations/maintenance cost estimates were developed for this project using the Corps’ M-CACES program.
