Congestion Management Program


In June 1990, Proposition 111 was passed, which made additional funding available for transportation projects through a nine cent increase in the state gas tax and mandated that each county with 50,000 or more residents develop a Congestion Management Program (CMP).  As Orange County’s designated Congestion Management Agency (CMA), OCTA is responsible for the conformance monitoring and biennial updating of Orange County’s CMP. 

Although the passage of AB 2419 (statutes of 1996) provided an opportunity to opt out of the CMP process, OCTA’s Board of Directors elected to continue with it because the data helps to satisfy federal Congestion Management Plan requirements and similar efforts were required as part of the Measure M Growth Management Program (GMP). Although the GMP ended with the sunset of Measure M in 2011, the CMP remains relevant as a requirement for local jurisdictions to receive Measure M2 funds.

CMP Preparation Manual

This manual is intended to help local jurisdictions comply with the requirements of the state CMP legislation (California Government Code Section 65088-65089.10). To maintain eligibility for transportation funding, local agencies must submit the following checklists to OCTA by June 30 of every odd year (i.e., 2011, 2013, etc.) to demonstrate compliance:

  • Consistency with Level of Service (LOS) Standards
  • Adoption of Capital Improvement Programs (CIPs)
  • Adoption and Implementation of a Program to Analyze the Impacts of Land Use Decisions, Including an Estimate of the Costs Associated with Mitigating those Impacts
  • Adoption and Implementation of Deficiency Plans When Highway and Roadway Level of Service Standards are Not Maintained

The chapters of this manual include instructions for completing these checklists as well as descriptions of the associated Orange County CMP elements. This manual replaces the Preparation Manual published in 1995 and will be updated as needed.
