Document Description
The Contra Costa County Flood Control and Water Conservation District (District) in partnership with American Rivers, a national non-profit organization that protects wild rivers, restores damaged rivers and conserves clean water for people and nature, proposes to improve flood conveyance capacity, to meet the District's standards for 100-year flood protection, and restore native vegetation along an approx. 4,000 linear foot section of Marsh Creek. When implementation is complete, the project would include up to 1.0 acre of frequently inundated floodplain (seasonal wetland), 1.87 acres of woody riparian vegetation, and 1.87 acres of grasslands and native scrub. The project would also enhance habitat and recreation within the watershed. The segment just upstream of Dainty Avenue (Phase I) was widened in 2000 by the District; native riparian vegetation may also be planted in this section as part of this project to provide a continuous riparian corridor with the existing riparian vegetation upstream of this segment. Placement of boulders and large woody debris would be placed in some portions of the low-flow channel to create in-stream habitat as well as rock to protect the banks and culvert outfalls. Real Property transactions, including right-of-way acquisition and temporary construction easements for access and staging areas and permanent easements for access and maintenance may be necessary in support of this project. Construction is anticipated to begin summer 2018 and may take up to two construction seasons to complete. Excavation and grading activities would occur during the dry season (July to October) with plant restoration occurring afterwards (November to December).
