I-15/Clinton Keith Road Interchange Caltrans EA 0F580

The County of Riverside proposed the reconstruction of the existing Clinton Keith I/C on I-15.  The County acting as the lead agency for the project (even after the incorporation of the City of Wildomar in 2010), which obtained the PA/ED milestone in December 2009 after overcoming many environmental related issues.  The designated Projet Manager, Southstar Vice Presient Jason Bennecke, has worked with the project from the July 2008 approval of the Geometric Approval Drawings (GAD’s) to the present completion of construction phase work.  His work also included supervision of the risk design of the PS&E.

The purpose of this $22 million project is to accommodate increased traffic, reduce traffic congestion, improve traffic safety, improve reliability of goods movement, and reduce people/goods movement conflicts.  The Construction phase of work (approximately $13.5 million) began in February 2012 with the award of the contract to the Griffith Company and is expected to be completed by Spring 2013.  The scope of work involves interchange (IC) improvements in the County of Riverside from 0.5 miles south of the Clinton Keith IC to 0.5 miles north of the Clinton Keith IC. The existing overcrossing will be widened to 8 lanes total.  Ramps of the existing tight-diamond configuration interchange will be widened, and auxiliary lanes will be constructed.  The ramps will be built with 40-year Joint Portland Cement Concrete Pavement (JPCP).

Stakeholders include: California Highway Patrol (CHP), FHWA, Riverside County Transportation Commission (RCTC), US Fish and Wildlife (USF&W), California Fish and Game (F&G), County of Riverside, California Department of Transportation (Caltrans), City of Wildomar.
Issues affecting delivery:

•    Trees – There were a number of existing eucalyptus trees that needed to be removed.  There was significant disagreement between Caltrans and the County over the ratio used to replant the trees.  Ultimately, a compromise was reached that allowed the PS&E to be finalized.
•    Risk Design – The project is funded entirely with local funds and there was one (1) build alternative in the PR.  The County chose to move forward with 35 and 65% PS&E submittals to Caltrans during PA/ED.  This reduced the overall delivery by nearly one year.
•    Utility coordination – Several utilities required relocating and issuance of encroachment permits.  The Southstar representative worked closely with the County, Caltrans permits staff, and Utility companies to quickly resolve issues related to the permitting process so that permits could be issued on time before they became critical path tasks.
•    Materials – This project went through PS&E during the period when the requirement for LCCA’s began being enforced by Caltrans.  There were numerous questions brought forth by the County during the process, all of which were ultimately coordinated and answered with the help of the Southstar representative.
•    ADL Spec – At the 11th hour, after the project had been awarded to the contractor, a Caltrans environmental planner realized that there might possibly be an erroneous spec in the bid package related to Aerially Deposited Lead (ADL).  Swift and effective coordination by the Southstar representative between the County Environmental staff, Caltrans Environmental and Construction units, and the design engineering firm (URS) led to avoidance of a potential delay in starting construction.
