The California Department of Fish and Wildlife (CDFW) has executed Streambed Alteration Agreement number 1600-2019-0087-R2, pursuant to section 1602 of the Fish and Game Code to the project Applicant, California Department of Water Resources as represented by Anitra Pawley. The project is limited to restoration of the Grizzly Slough floodplain with the goal of reintroducing tidal exchange and seasonal flooding to a previously leveed system. As a part of the project, channel and vegetation restoration will occur throughout the 465-acre site to reduce flood risk and provide habitat beneficial to native fish and wildlife. Project activities include excavating/grading a channel network and floodplain habitat, construction of a new setback levee along the property's southern boundary, repairing a portion of the western levee, construction of new setback levee culverts, excavation of material for new the setback levee, removal of existing vegetation, restoration planting and seeding, enhancement of agricultural lands, and a levee breach. Infrastructure improvements including access roads, staging areas, and demolition of facilities will also occur. The project includes the following activity subject to Notification: Levee Breach. Upon completion of other restoration activities outlined above, the levee between Grizzly Slough and the project site will be excavated. The breach will feature a trapezoidal channel will be approximately 150 feet wide. Excavating and lowering approximately 240 linear feet of levee, approximately 5000 cubic yards will be excavated and rock slope protection may be used along the banks of the breach area. Excavating will occur from the levee using a long-reach excavator to minimize in channel work. Excavated materials will be reused onsite.
