Description:

The proposed project consists of upgrading and reconfiguring the existing 1-10/Cherry Valley
Boulevard Interchange in the City of Calimesa, Riverside County.
The purpose of this project is to relieve congestion and improve traffic operations at the IIO/
Cherry Valley Blvd. Interchange. It will also address increased travel associated with the
existing and planned development anticipated in Calimesa and surrounding areas.
Four alternatives are proposed, including a No-Build alternative:
Alternative 1 (No-Build)- No reconstruction or improvements, except routine maintenance.
Alternative 2 (Roundabouts)- Reconfigure the current diamond interchange and reconstruct
roundabouts at each existing ramp intersections with two lanes in each direction.
Alternative 3 (Diverging Diamond) - Reconstruct the current diamond interchange into a
diverging diamond interchange and widen Cherry Valley Blvd. to two lanes in each direction.
Alternative 4 (Partial Cloverleaf) - Reconstruct the current diamond interchange into a partial
cloverleaf configuration and widen Cherry Valley Blvd. to two lanes in each direction.
The proposed project is not anticipated to result in a use of Section 4(f) resources, there are no
high mitigation costs or complex issues related to the Endangered Species Act, and no issues
related to logical termini or independent utility. Partial to full Right of Way acquisition is
anticipated for up to 13 parcels but none of the build alternatives are anticipated to result in
residential or business relocations.
Because the project will not result in substantial environmental impacts associated to any
alternative, a Routine Environmental Assessment is the appropriate NEPA level document.
