How much traffic would the project generate?

The traffic analysis studied the project’s potential impact using a methodology that allows the Town to distinguish between current traffic conditions from the project’s contribution to an existing traffic baseline.   Under law, a project is only required to mitigate its own impacts to the baseline rather than to fix all existing problems.   

The analysis concluded that the project would increase the daily traffic volume along the Diablo Road corridor, west of Mt. Diablo Scenic, by 4-percent.  The project would also be required to contribute its fair share of future road improvements.

As a contribution toward improving the travel corridor, the project applicant has agreed to improve the intersection of Diablo/Green Valley/McCauley intersection by extending the westbound right-turn and through lanes.  This would increase the number of cars that can move through one traffic signal cycle and decrease the overall wait time, improving the operation of the intersection. 

It is also worth noting that the methodology used in the traffic analysis has been upheld by the both the Contra Costa County Superior Court (2013) and the California Court of Appeal (2015).  {Internal Note: these will be linked to documents}
