Public Works - Lake Nacimiento Watershed Mercury Sediment Reduction Project; ED00-359 (300341)

A proposal by the County Public Works Department to reduce the mercury sediment load that enters Las Tablas Creek and Lake Nacimiento, from Cypress Mountain Drive, a rural, unpaved County road. The physical improvements of the project involve: paving 3.3 miles of Cypress Mountain Drive, installing approximately 430 feet of bioengineered streambank stabilization, replacing old and installing new drainage culverts, and installing approximately 600 feet of roadside filter strips. The project will result in the disturbance of approximately 10.4 acres. The project is being conducted with the support and assistance of the USEPA, California Department of Health Services, and the Central Coast RWQCB. Funding has been provided through an agreement with the State Water Resources Control Board under the Proposition 40 Integrated Watershed Management Implementation Grant Program. The project is located in the Agriculture and Rural Lands land use categories, on Cypress Mountain Road, between Klau Mine Road and Chimney Rock Road, approximately 9 miles west of the community of Templeton and 6 miles north of Cayucos, in the Adelaida planning area.
