Reach 4B and Eastside Bypass

Reach 4B of the San Joaquin River is a 32.5-mile stretch that begins at the Sand Slough Control Structure and extends to the confluence of the Eastside Bypass and San Joaquin. Reach 4B has been further divided into two subreaches; Reach 4B1 from the Sand Slough Control Structure to the Mariposa Bypass, and Reach 4B2 from the Mariposa Bypass to the confluence of the Eastside Bypass and the San Joaquin River.

Reach 4B and Eastside Bypass project consists of incorporating new floodplain and related riparian habitat to ensure conveyance of at least 4,500 cfs through Reach 4B, modifications to ensure fish passage, and modifications in the Eastside and Mariposa bypass channels to support anadromous fish migration.

The Eastside Bypass Improvements Project Initial Study/Final Environmental Assessment consists of the December 2017 Draft IS/EA (Part 1, Part 2, Part 3, Part 4), the Finding of No Significant Impact and Air Quality and Greenhouse Gas Emissions; Biological Resources (Appendices A and B); public comments received (Appendix C); responses to public comments and minor text changes to the EA/IS (Appendix D); Endangered Species Act compliance documentation (Appendix E); and, National Historic Preservation Act Section 106 compliance documentation (Appendix F).
