Springtown Trunkline Sewer Project (Recirculated MND)

The Springtown Trunkline Sewer Project and Arroyo Las Positas Trail Project in Livermore, California, involve two primary components: the upgrade of an existing sewer line and the construction of a new public access trail. These elements are located on approximately the same alignment, situated between the south end of Redwood Road, adjacent to Arroyo Los Positas, and extending south to Las Colinas Road. The project is managed by the City of Livermore and is classified under NAICS code 237110. A critical component of the project is environmental compliance regarding the California tiger salamander, a threatened species under the California Endangered Species Act. The project will impact 8.52 acres of habitat, consisting of 6.77 acres of temporary impacts and 1.75 acres of permanent removal. To address this, the California Department of Fish and Wildlife issued Incidental Take Permit No. 2081-2022-090-03, which authorizes the incidental take of the species. This permit is supported by a Notice of Determination confirming that the project will not have a significant environmental effect within the jurisdiction of the CDFW, provided that specific mitigation measures and a monitoring plan are implemented.
