BACKGROUND
The final designs for the Bale Slough - Bear Creek Restoration Project, Groups A-C, were completed in 2022. Construction of the Group A restoration sites was completed in the summer of 2023. The District has been awarded sufficient grant funds from the Wildlife Conservation Board and United States Environmental Protection Agency to implement the next phase of the Project, the Group C restoration sites. With funding now in place, this phase of the Project is ready to go out to bid. Construction of Group C is anticipated to be completed in 2025 with completion of the last restoration Group, Group B, dependent on receiving additional funds.
The engineers estimate for constructing Group C is $2,505,600 and the attached map, Exhibit A, shows the location of the entire Bale Slough - Bear Creek restoration Project including the Group C restoration sites 12-14. Restoration actions will include expansion and enhancement of a large wetland feature just upstream Highway 29 through grading and installation of in-stream habitat features, reconnecting Bear Creek to its historic floodplain, increasing habitat diversity within the riparian zone through the management and removal of non-native vegetation and installation and maintenance of native vegetation.
Requested Actions:
1. Approve plans and specifications for the Bale Slough - Bear Creek Restoration Project
2. Authorize advertisement for sealed bids for Group C restoration Sites and opening of the bids at a time, date and location to be published by the District Manager pursuant to Public Contract Code section 20150.8.
