In June, 1990 California voters approved legislation which increased funding for California's transportation system. With the passage of Proposition 111 there were new requirements for the transportation planning process that requires urbanized counties, such as San Joaquin County, to prepare, adopt, and biennially update a Congestion Management Program (CMP). The intent of the state CMP legislation is to address the problem of increasing congestion on California's highways and principal arterials through a coordinated approach involving state, regional, county, and city transportation and land use agencies, transit providers and air pollution control districts. The CMP legislation is also intended to facilitate an integrated approach to programming transportation improvements. By creating a forum for state, regional, and local transportation and land use agencies to address regional and multi-jurisdictional issues related to congestion, land development, and air quality, the CMP ensures that limited transportation funds are more efficiently invested.

The 2005 Federal transportation legislation, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). SAFETEA-LU included a “Congestion Management Process” targeted at reducing SOV travel without increasing roadway capacity. Areas designated as non-attainment of federal air quality standards such as San Joaquin County, the federal Congestion Management Process stipulates that for any project that results in a significant increase in the carrying capacity of single occupancy vehicles (SOVs) and is also proposed to be advanced with federal funds, an analysis is required to demonstrate that travel demand reduction and operational management strategies have been implemented to the full extent possible on the subject roadway. If the analysis demonstrates that despite these strategies additional SOV capacity is still required, the intent of the federal Congestion Management Process is to establish a process to identify all reasonable strategies to manage the SOV facility effectively. The most recent federal transportation bill: Moving Ahead for Progress in the 21st Century (MAP-21) continues the requirements for implementing the Congestion Management Process.

Other transportation planning mandates related to the state/federal congestion management mandates include:

  • AB-1358 (Government Code 65040.2, 65302) for addressing multi-modal “complete streets” concepts in city/county general plan circulation elements.
  • SB-375 – Redesigning Communities to Reduce Greenhouse Gases requires Metropolitan Planning Organizations to develop “Sustainable Communities Strategies” (SCSs) to achieve quantifiable targets for reducing greenhouse gas emissions through more efficient development and better coordination. SB 375 streamlines the environmental review process for certain new development projects located near transit stations.
  • Revised CEQA Guidelines (Section 15064-7, Appendix G) requiring local land use development projects to conform to both the CMP LOS standards and CMP TDM measures.
