PROJECTS

The project involved construction of the uppermost segment of the City of Rancho Cucamonga’s master storm drain facilities for conveyance of drainage flows to the Cucamonga Creek Channel. Improvements included installation of approximately 800 linear feet of 66-inch diameter reinforced concrete pipe (RCP) and 2,600 linear feet of 60-inch diameter RCP. A transition structure was constructed at the upstream terminus of the storm drain mainline to intercept both regional runoff and flows from State Route 210. The storm drain alignment generally extends from the Pacific Electric Trail at the southern end to 19th Street to the north.

Additional infrastructure elements included 15 storm drain laterals with catch basins, 15 junction structures, and 9 manholes.

The project also included reconstruction of Amethyst Avenue throughout the entire reach of the storm drain mainline, featuring new asphalt concrete pavement, construction of concrete curbs and gutters, and construction of ADA-compliant curb ramps.
