Full History

The American River Common Features, 2016 Flood Risk Management Project(ARCF 2026 Project), Supplemental Environmental Impact Statement/Subsequent Environmental Impact Report (SEIS/SEIR) XIV was prepared to address design refinements made to the authorized project from the 2016 ARCF General Reevaluation Report (GRR) Final EIS/EIR. Refinements include changes to engineering design modifications, footprint expansions, and compensatory habitat mitigation associated with the Magpie Creek Project, American River Erosion Contract 3B, 4A, and 4B, Sacramento River Erosion Contract 3, American River Mitigation Site, Sacramento River Mitigation Site, and installation of a Piezometer Network.

The public review period for the Draft SEIS/SEIR began on December 22, 2023, and was extended to February 23, 2024.  Two virtual public meetings were held on January 10 and 16, 2024. During public review, the Project Partners received three letters from federal agencies, two letters from state agencies, five letters from local agencies, and 964 letters from individuals; all of which are documented in Appendix I Public Involvement of the Final SEIS/SEIR.

In addition to the comment record, Appendix I contains the comment responses which are indexed by agency or last name (public), and fifteen master responses which grouped common concerns and provided correlating rationale or solutions. Public concerns were also addressed in the following appendices prepared for the Final SEIS/SEIR:

• Appendix G Engineering
• Appendix H Wild and Scenic Rivers Act Compliance
• Appendix J Health Risk Assessment

Preparation for the Final SEIS/SEIR included completion of Clean Water Act Section 404 compliance (Appendix K 404(b)(1) Alternatives Analysis), and Endangered Species Act Section 7 compliance with Biological Assessments and Biological Opinions from U.S. Fish and Wildlife Service and National Marine Fisheries Service (Appendix L).

The Final SEIS/SEIR will be published and made publicly available in the Federal Register, and at the below links, on Friday, May 9, 2025. The Final SEIS/SEIR will be available for a 30-day waiting period, beginning May 12, 2025, and ending June 11, 2025.

Following the 30-day waiting period, USACE will sign the Record of Decision to conclude NEPA compliance. An informational and certification briefing of the SEIS/SEIR will be presented for consideration of approval by the CVFPB in the coming months. Upon approval, the CVFPB will certify the Final SEIS/SEIR under CEQA.

Announcements for future public outreach associated with the Project Components in this SEIS/SEIR will be posted on www.sacleveeupgrades.com
