West Yost served as the Owner’s Agent for the landmark Davis-Woodland Water Supply Project (DWWSP). The DWWSP supplements the existing groundwater-only systems throughout the region with a new primary surface water supply, serving over two-thirds of the urban population in Yolo County. The project facilities include a new intake on the Sacramento River, over 14 miles of transmission pipelines, a new 30 mgd capacity Water Treatment Plant, and distribution pipelines delivering treated water to the Cities of Woodland and Davis, and to the UC Davis campus. As the Owner’s Agent, West Yost represented the JPA owners to first define the project and develop the most appropriate project delivery approach that best allocated project risk while ensuring the highest quality project. After leading the project partners through a thorough evaluation of project delivery approaches against numerous criteria, the Design-Build-Operate (DBO) approach was found to be the most beneficial. West Yost then developed the overall DBO procurement strategy, designed and implemented a multi-stage procurement process, and negotiated a long-term service agreement between the JPA and the successful DBO team.
West Yost completed successful negotiations of the DBO agreement with the highest ranked DBO team. West Yost continues to provide contract management oversight, budgeting and cost control, master and basic project scheduling, and team member/subconsultant coordination.

“I love working with our great team at West Yost to solve challenging projects in partnership with our clients. I get tremendous satisfaction seeing our clients implement projects that make a positive impact for their communities.
The Davis Woodland Water Supply Project is a special project for me. I began working on the project in 2007 and continue to serve the Woodland-Davis Clean Water Agency today. The project brought a sustainable surface water supply to the Cities of Davis and Woodland and UC Davis, which also happens to be the area where I live.”

“I enjoy my work because I have really great coworkers. I have interesting assignments that require creative analytical solutions. It is rewarding to me to work with and mentor younger staff. It is my personal challenge to help turn written documents into clear, understandable work products.
One of my favorite ongoing accomplishments has been Woodland-Davis Clean Water Agency’s Davis Woodland Water Supply Project — From the 2011 analysis of long-term water supplies to the current Water Supply Reliability Study, and just about everything in between.”

“I get very excited when an existing client tells a prospective new client to hire us and that happens unsolicited. Also, meeting with clients always float’s Captain Jim’s boat.
Recently we won work at the City of San Diego by virtue of my long-standing relationships. It is very rewarding to build relationships and rekindle relationships with existing clients!
