Our regional strategies in housing, transportation, and economic development improve the quality of life for Western Riverside County and San Diego residents.

About Us

The goal of the I-15 Interregional Partnership (IRP) is to collaborate on mutually beneficial housing, transportation, and economic planning to improve the quality of life for residents of western Riverside County and San Diego regions through the identification and implementation of short-, medium-, and long-range policy strategies.

The I-15 Interregional Partnership (I-15 IRP) is a voluntary compact between local elected officials representing the Western Riverside Council of Governments (WRCOG), SANDAG, the Riverside County Transportation Commission (RCTC), and the Riverside Transit Agency (RTA), as well as Caltrans and other affected agencies and organizations.

The primary goal of the I-15 IRP is to foster collaborative strategies in economic development, transportation, and housing that will improve the quality of life for residents in both counties by reducing the impacts of interregional commuting, creating more jobs in housing-rich areas and more housing in jobs-rich areas. Centered on I-15, this two-county commute corridor extends from central San Diego to the cities of Lake Elsinore, Perris, and Hemet.

Through various grants, the partner agencies have been able to pursue two phases of the partnership. New funding from Caltrans has been secured by WRCOG, SANDAG and RCTC, to pursue a third phase. The emphasis for Phase III will be to develop a Strategic Transportation Implementation Plan to improve the transportation system in a 5- to 15-year time horizon, using a multi-modal approach.  The I-15 IRP will also pursue coordinated economic development and housing strategies as identified in Phase II.
