Old State Highway Pipeline Replacement project

The Old State Highway Pipeline Replacement project, managed by the Placer County Water Agency in California, involves the replacement of approximately 1,650 linear feet of 8-inch water main and 1,700 linear feet of 6-inch sewer main. The scope of work includes the replacement of services and appurtenances, with construction primarily occurring within a 20-foot corridor of paved roadway and designated staging areas. The project is located within existing County and PCWA utility right-of-way, specifically along Old State Highway from the Taylor Road intersection heading east, as well as within Threlkel Street and Buena Vista Avenue in unincorporated Newcastle, Placer County. The project is classified as a forecast under NAICS code 237110 and is exempt from certain environmental reviews under Class 2, Section 15302, as it replaces existing public facilities with substantially the same purpose and capacity. Site activities will involve minimal ground disturbance but will require some vegetation removal, tree trimming, and potential tree removal. Administrative oversight is provided by the Placer County Water Agency, with Steven Millett serving as the Associate Engineer and Heather Trejo as the Environmental Scientist.
