SB375 Definitions and Resources


SB 375 Definitions and Resources

This section is designed to provide an overview of basic terms and resources related to SB 375, which relies on regional collaboration by local officials to address California’s goals for reducing that portion of the emissions of greenhouse gases that stems from automobile travel. The law coordinates three important planning activities into a new integrated planning process:

  • The regional transportation plan (RTP);
  • The regional housing needs assessment (RHNA); and
  • Updating the housing element of local general plans.

Regional Transportation Plans

A regional transportation plan (RTP) outlines transportation investments for a region. It is drafted by a metropolitan planning organization (MPO) or regional transportation planning agency (RTPA) every four years (five years in regions that have attained federal air quality standards) and includes a 20-year outlook for likely growth in the region. The RTP is the basis for state funding of transportation projects. Projects that are not in the RTP cannot be “programmed” for state or federal funding.


Regional Housing Needs Assessment (RHNA)

The Regional Housing Needs Assessment (RHNA) is mandated by State Housing Law as part of the periodic process of updating local housing elements of the General Plan.


Public Participation Plans

To increase public participation and enhance collaboration between residents, state agencies and local agencies in regional planning, SB 375 requires specific public participation plans for five types of decisions.
