Tolay Creek Wetland Restoration Project
The Tolay Creek restoration project's goal is to restore 435 acres of diked, historic wetlands to tidal salt marsh, providing critical habitat for threatened and endangered species.

The Tolay Creek Biotechnical Levee Enhancement project is designed to improve wetland-upland transitional habitat and improve levee integrity of the Tolay Creek site. Primary activity will be to enhance earthen levees (which are part of the Tolay Creek tidal restoration) by installing geotextile fabric, and establishing native vegetation. Native grasses and shrubs will be planted to provide habitat and protect the levee slope by reducing the threat of soil erosion. This project will enhance transitional upland habitat for small mammals (including salt marsh harvest mouse), and provide high-water refuge habitat. The upland vegetation will also provide cover for ground-nesting birds, as well as provide protection from wave action for this critical perimeter levee.
