New Da Vall Drive Interchange 08 - Riv - 10 – 39.5/43.4 Project Study Report – Project Development Support
March 2023
1 1. INTRODUCTION
Project Description:
City of Cathedral City (City), in cooperation with California Department of Transportation (Caltrans) District 8, City of Ranch o Mirage and County of Riverside, is proposing to construct a new interchange at Da Vall Drive on Interstate 10 (I-10). The project will include bridges over I-10 and the Union Pacific Railroad (UPRR), and street extension and widening along Da Vall Drive. The limits of the project will generally extend from the existing Ram on Road/Da Vall Drive intersection, northerly across I-10 and UPRR, to a new intersection with Varner Road. The project will also include utility relocat ions, right-of-way acquisition, flood control improvements (crossing over the Moron go Wash and Willow Hole floodplains), traffic signals, and ramp metering systems. In addition, auxiliary lanes along I-10 between Da Vall Drive and its adjacent interchanges may be required.
There are four alternatives that are considered for further study in the Project Approval & Environmental Document (PA&ED) phase. These alternatives are:
• Alternative 1: No build
• Alternative 2: Partial cloverleaf interchange
• Alternative 3: Diamond interchange
• Alternative 4: Single point urban interchange
Da Vall Drive is included in Coachella Valley Assoc iation of Governments’ (CVAG) overall Master Plan and has received high ra nking among proposed interchanges in their Transportation Project Prioritization Study (with 13 Criteria Points). As a result, CVAG is providing all the funding for this phase of the work.
The funding source for the next phases has not been identified but the Project will most likely be funded by a combination of local, st ate, and federal funds. Caltrans will provide oversight through the construction phase of the Project.

3 The remaining capital outlay support, right-of-way, and construction components of the project are preliminary estimates and are not suitable for programming purposes.
Either a Project Report or a supplemental Project I nitiation Document (PID) following the format of a PSR will serve as the pro gramming document for the remaining components of the project. A Project Report will serve as approval of the “selected” alternative.
The City and Caltrans have an executed cooperative agreement dated 5/10/2019 to complete a Project Study Report-Project Development Support (PSR-PDS) for PID.
Subsequent cooperative agreements will need to be d eveloped for future phases of the project, including PA&ED; Plans, Specifications & Estimates (PS&E); and Construction.
