The County of Riverside, in cooperation with the California Department of Transportation (Caltrans) and the City of Palm Desert, proposes to construct a new interchange on Interstate 10 (I-10) at Portola Avenue in the City of Palm Desert between the Monterey Avenue and Cook Street interchange. The proposed project would continue Portola Avenue in a northwest direction from Dinah Shore Drive to the realigned Varner Road, including a new bridge structure over I-10 and the Union Pacific Railroad. The proposed project would serve to reduce existing and forecasted traffic congestion on Monterey Avenue and Cook Street interchanges on I-10 and would accommodate planned infrastructure improvements in the project vicinity.

A copy of the Initial Study with proposed Negative Declaration has been prepared and is available for public review beginning December 4, 2017 through January 4, 2018. During the review period, a copy of the draft Negative Declaration will be available at the City of Palm Desert, Public Works Department, 73-510 Fred Waring Drive, CA 92260; or an electronic copy of the Draft IS/EA can be also viewed from the Caltrans website:
