Zayante Area Sediment Source Reduction Plan

z1Client: County of Santa Cruz

Waterways staff, in conjunction with SH+G, developed sediment load allocation and recommendations to reduce chronic fine sediment inflow as a basis for a Total Maximum Daily Load (TMDL) for the San Lorenzo River Watershed in Santa Cruz County. Work included development of a GIS database of streams, subwatershed drainage basins and road networks. Erosion rates developed for the Soquel Demonstration Forest by California Department of Forestry were adapted to the San Lorenzo River watershed to calculate sediment yields from roads and other erosion sources. The project aimed to improve impaired fisheries conditions for steelhead and coho.
