Secret Ravine Floodplain Restoration

Placer County, California

Foothill Associates assisted the Placer County Flood Control and Water Conservation District with a successful grant proposal for $300,000 in funding from the Department of Water Resources Urban Streams Restoration Program to fund the Secret Ravine floodplain restoration project. This project implemented a multi-objective flood management project along two reaches of Secret Ravine in Rocklin, California. It attenuated flood flows in Roseville downstream by restoring the natural values and functions in upstream reaches of the creek using an easement purchase, channel reconfiguration, and streambank stabilization using revegetation and bioengineering techniques. It also improved public access and provided for interpretive signage. Along with volunteers from several non-profit community groups, students and teachers from the Sierra College participated in planning, implementation, and monitoring of the project.

Primary project objectives are to improve the relationship of the creek channel to its floodplain and increase floodplain storage capacity.
