The TRANSPLAN Committee coordinates the transportation interests of the communities in eastern Contra Costa County, California.

This region, known locally as “East County,” has been one of the fastest growing residential areas in California for more than a decade.  With its population now approaching a third of a million people and still growing, the region’s infrastructure is overburdened, particularly the transportation system.  In addition to local transportation needs within East County, there is a heavy out-commute every day from East County’s residential areas to job centers that are miles away in Concord, Livermore, Pleasanton, Silicon Valley and elsewhere.  This has created a need for major improvements to the transportation system.  

Since our transportation system hasn’t kept up with this surging population, East County is working on numerous efforts to expand its system of streets and highways, public transportation and bikeways.
