Document Description
The Lower Marsh Creek Stream Corridor Restoration Program (Program) is a creek restoration and flood risk reduction Program proposed by the Contra Costa County Flood Control and Water Conservation District ("District") and American Rivers, a national nonprofit organization that protects wild rivers, restores damaged rivers, and conserves clean water for people and nature. The goal of the Program is to incentivize willing landowners and developers to work with the District and other local partners to improve Marsh, Deer, and Sand creeks. Implementation of the proposed Program will result in: 1) improved habitat conditions for fish, birds, reptiles, and amphibians by providing a mosaic of riparian, floodplain, wetland, and aquatic habitat types for these species to utilize, 2) expanded channel capacity to meet or exceed flood channel conveyance capacity, 3) improved local water quality by shading the creek and reducing mobilization of fine sediments, and 4) improved public recreational opportunities. The CEQA document has been developed to put in place the environmental compliance mechanism necessary to alleviate uncertainty and complexity associated with implementing creek restoration projects, which would further incentivize landowners and developers to participate. Construction would occur during the summer and fall months and occur over an approximately a 45-working day period. Excavation and grading activities would occur during the dry season (July to October) with plant restoration occurring afterwards (November to December}. Construction activities will be generally limited to the hours between 7:00 a.m. to 5:00 p.m. 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 Program projects.
