City of Rancho Palos Verdes Storm Drain Point Repair

CWE is providing design services to the City of Rancho Palos Verdes for the Storm Drain Point Repair project. The City completed a storm drain lining project in 2013, and during that project, a number of pipes were identified as requiring replacement or significant repairs before lining could be implemented. CWE is designing over 1,500 linear feet of replacement and repairs so future lining can be installed. CWE is designing these replacement and repairs for storm drains in 11 different locations. Additional tasks were added to protect downstream natural drainage courses from erosion that is causing bank failures. Tasks included: reviewing existing records and data, conducting hydrologic and hydraulic analyses for each of the sites, performing topographic surveys, performing geotechnical investigations, locating utilities, conducting biological assessments, obtaining all necessary permits, and preparing Plans, Specifications, and Estimates (PS&Es) for each of the 11 project sites.
