The ARCF 2016 Flood Risk Management Project SEIS/SEIR XIV was prepared to address design refinements made to the 2016 ARCF General Reevaluation Report (GRR) Final EIS/EIR. Refinements include changes to designs 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.

USACE and the non-federal Partners received public comments from December 22, 2023, until February 23, 2024, during the extended comment period of 63 days. We are no longer accepting comments and have shifted focus to finalize the comprehensive comment log to ensure every comment is captured and adequately responded to by a subject matter expert, including environmental resources, engineering, project management staff. For perspective, we have logged nearly 900 comment letters. The Public Involvement appendix of the Final SEIS/SEIR will include all public and agency comments and responses, and the resulting text changes made to the SEIS/SEIR.

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

Any further questions regarding the ARCF 2016 Project can be directed to USACE. Public Affairs Office: SPK-PAO@usace.army.mil
