Besides being responsible for the Measure J Growth Management Program, the Authority serves as the Congestion Management Agency (CMA) for Contra Costa County. As the CMA, the Authority must, under State law, prepare a Congestion Management Program (CMP) and update it every two years. The CMP is meant to outline the CMA's strategies for managing the performance of the regional transportation within its county.
Each CMP must contain several components:
Traffic level-of-service standards for State highways and principal arterials
Multi-modal performance measures to evaluate current and future system
A seven-year capital program of projects to maintain or improve the performance of the system or mitigate the regional impacts of land use projects
A program to analyze the impacts of land use decisions
A travel demand element that promotes transportation alternatives to the single-occupant vehicle
One of the key benefits of being a CMA is that it gives the county a "place at the table" in discussions with other counties and regional and State agencies and provides a cooperative process for allocating various transportation funds.
