The proposed watershed plan will provide a science-based blueprint to guide long term restoration of Sausal Creek.This project will collect and compile data to produce an assessment of the Sausal Creek watershed using a workshop format to engage and educate other local watershed groups.The erosional effects of stormwater runoff and non-point source pollution in urban creeks will be the primary focus. The assessment will include designs for projects to reduce peak stormwater volumes and lower erosion rates along the creek channel and reduce flood volumes in the most downstream area of the creek.
FOSC has worked actively to restore riparian and aquatic habitats in the Dimond Park reach of Sausal Creek. But the restoration of Sausal Creek is at risk from watershed development, antiquated storm drains, high siltation and water quality impairments. These problems lead to excessive channel erosion in the headwaters of the system from urban development and high levels of pesticide contamination. As a guide to long term restoration of Sausal Creek, the proposed watershed plan will collect existing studies, FOSC and agency monitoring data, complete detailed hydrologic, geologic and engineering analyses, model and fully evaluate watershed processes and prepare project implementation designs. The plan will identify sources of urban runoff responsible for excessive creek erosion and identify measures to mitigate this problem. The plan will also evaluate potential creek day-lighting and restoration areas, invasive plant removal areas, stormwater detention areas and needed monitoring.
