BACKGROUND:

The Camino Tassajara/Tassajara Road Realignment Project is a joint project with the City of Dublin that includes roadway re-alignment and roadway widening on approximately 4,200 feet of Camino Tassajara/Tassajara Road between Windemere Parkway in Contra Costa County to Palisades Drive/Kylemore Circle in the City of Dublin. The County Public Works Department has been coordinating with the City of Dublin on this project since 2011 to determine the ultimate alignment of the roadway and more recently to finalize project scope and costs.  
  
Realignment of the roadway will improve safety for motorists and accessibility for bicyclists and pedestrians along Camino Tassajara. The project will improve sight distance by removing the S-curve and connectivity between Alameda and County Costa Counties. Widening of the roadway from two-lanes to four lanes will also increase capacity to accommodate projected future traffic volumes, consistent with the County General Plan. The additional pavement width will provide Class II bicycle lanes in accordance with the 2018 Contra Costa Countywide Bicycle and Pedestrian Plan. An additional separated shared use path will bridge the City’s trail network to the existing sidewalk and trails along Windemere Parkway and the 2019 constructed bike lanes on Camino Tassajara.  
  
The purpose of this Agreement is to set forth the parties’ financial and project responsibilities pertaining to design, environmental clearance, right of way acquisition and construction of the roadway improvements. With this Agreement, the design phase for a new roadway alignment can be started with the intent to get the project “shovel ready”. The City of Dublin will contribute $3.1 million for this work. The City will identify funds for construction before the parties move that phase of the Project. The JEPA is structured to allow design activities, including environmental clearance and right of activities to commence, with the construction phase only to begin by written agreement of both parties’ authorized representatives. The total project cost is approximately $30 million with the County’s share estimated at $17.5 million.
