body
BACKGROUND
The Bale Slough - Bear Creek Restoration Project will continue restoration activities within the Napa River Watershed that were started with the Rutherford Reach Restoration Project and the recently completed Oakville to Oak Knoll Restoration Project. The 1.6-mile Project reach has been divided into three construction groups (A-C), encompassing fourteen (14) distinct restoration sites. The District has completed the environmental review of the Project as required by CEQA, and a Mitigated Negative Declaration was adopted. The project goals include reducing sediment loads and enhancing biological complexity throughout the river channel and riparian corridor. Construction of the Group A restoration sites was completed in 2023, and Group C will be completed in the summer of 2025 pending board approval of the construction contract. Construction of Group B is dependent on receiving additional grant funds which District staff plans to pursue as they become available.
Below are brief descriptions of the three groups in this restoration reach.
Group A (completed in 2023)
Group A consists of restoration sites 1-5 which is the initial construction group that currently has funding in place. Restoration will involve grading the creek channel to create diversity and to reconnect the waterway to its historic floodplain. The planned habitat structures and erosion protection will allow for a healthier ecosystem without creating additional risk to landowners in the area; work will be completed by the end of 2023.
Group B
Group B consists of restoration sites 6-11 which is unfunded. Restoration actions will be similar to Group A involving grading the creek channel to create habitat diversity and to reconnect the waterway to its historic floodplain.
Group C (The subject of this agenda item)
Group C consists of restoration sites 12-14 which is unfunded. Restoration actions will be similar to Group A and B involving grading the creek channel to increase habitat diversity and to reconnect the waterway to the channels historic floodplain with the addition of the expansion of a large wetland feature just upstream Highway 29.
