American River Common Features (ARCF) Supplemental EIS/Subsequent EIR
November 2, 2022 and November 30, 2022

USACE is preparing to draft a Supplemental Environmental Impact Statement/Subsequent Environmental Impact Review (SEIS/SEIR) to analyze changes made during final preliminary design of multiple contract actions within the American River Common Features (ARCF) project that could result in potentially significant environmental effects. This supplemental document will centralize where the public and agencies can look for the most current project information and will bring environmental considerations up to date. The SEIS/SEIR will focus on new or different features of project designs that have evolved since the original 2016 ARCF General Reevaluation Report (GRR) Final Environmental Impact Statement/Final Environmental Impact Report (FEIS/FEIR) was completed, while analyzing the potential environmental impacts of these changes. 

The Notice of Intent (NOI) to prepare the draft SEIS/SEIR can be found HERE.  
The NOI incorrectly states that the public comment period closes on November 31, 2022. A correction was made to accurately reflect the correct public comment period closing date of December 1, 2022. The correction can be found HERE. The public scoping period has been extended to December 31, 2022.

Virtual public meetings were held November 2 and November 30, 2022, to discuss the development of the Draft SEIS/SEIR. Public comments will be accepted until December 31, 2022, and can be submitted to ARCF_SEIS@usace.army.mil.
