Document Description
The Sonoma County Water Agency (Sonoma Water) is the Lead Agency under the California Environmental Quality Act (CEQA) for the proposed Santa Rosa Aqueduct and Russian River to Cotati Aqueduct Cathodic Protection Project (Proposed Project). Sonoma Water has prepared an Initial Study and Mitigated Negative Declaration (IS/MND) for the project in accordance with the California Environmental Quality Act (CEQA), the State CEQA Guidelines, and Sonoma Water’s Procedures for Implementation of CEQA. Project Description: Sonoma Water owns, operates, and maintains a 48-inch diameter concrete mortar lined steel water supply pipeline (the Russian River to Cotati Aqueduct) and a 42-inch steel water supply pipeline (the Santa Rosa Aqueduct) that provide water from Sonoma Water’s production facility to southern parts of portions of central, southern, and eastern Sonoma County. The Russian River to Cotati and Santa Rosa aqueducts provide essential water service to approximately 600,000 residents and businesses within the Sonoma Water’s service area. The Proposed Project would include the construction of a total of 31 Cathodic Protection Stations and 49 Test Stations at intervals along the Santa Rosa and Russian River to Cotati aqueducts; vegetation maintenance activities associated with both aqueducts; and vegetation management at one location on the Petaluma Aqueduct. The Proposed Project is needed because the existing corrosion protection systems along the aqueducts are in need of replacement. Failing to replace the existing system components could result in corrosion and failure of portions of the aqueducts in the future.
