Corridor Planning Program

SCAG's Regional Transportation Plan (RTP) identifies transportation needs in corridors and encourages planners and policy-makers to start preparing strategies for preserving corridors now for use in the future. Good planning can prevent the loss of rights-of-way needed for developing transportation facilities. Thus, rights-of-way preservation is a reasonable objective, particularly in areas where new development may block a long-range corridor. Corridor planning also provides input and clarification to the RTP on the design concept and scope of major transportation investments.

Corridor planning studies, also known as Regionally Significant Transportation Investment Studies (RSTIS), determine transportation need and evaluate alternatives. SCAG, as well as state and local transportation planning agencies, may initiate these studies. Each typically incorporates a "purpose and need" statement, alternatives analysis utilizing a range of performance indicators, record of community involvement, a locally preferred alternative selection and preliminary environmental documentation, as appropriate.

SCAG requests that, upon initiation of a RSTIS, project sponsors contact the RSTIS coordinator, Philip Law, at (213) 236-1841 or law@scag.ca.gov. For more information regarding RSTIS, please review the RSTIS Coordination Process adopted by SCAG's Regional Council in September 2010.

SCAG adopted policy and plans supported similar regional RSTIS and corridor planning projects in each of its published Regional Transportation Plans extending back to 1975.
