Title

Lower Putah Creek Restoration Project, Nishikawa Reach

Description

Supplemental Initial Study/Mitigated Negative Declaration for the proposed Lower Putah Creek Restoration Project, Nishikawa Reach, which is an element of the Lower Putah Creek Restoration Project, Upper Reach Project. SCWA proposes to complete channel restoration involving recontouring and realignment along a 0.5-mile section of the low-flow channel of Putah Creek, upstream of the Pedrick Road Bridge near Davis, California in Yolo and Solano counties. The project is part of a series of restoration activities intended to restore Putah Creek to a more natural condition that is self-maintaining and supports native plant and animal species. The project involves restoring a section of active channel that is currently in an over-widened condition. This project aims to create a narrow design channel in a more central, meandering form to create 0.5-mile of nearly continuous salmon spawning habitat across a gravel-rich floodplain. The project design includes grading of 11 acres to floodplain elevation, and construction of 15 riffles and several rock vanes.
