The I-15 IRP was established to foster collaborative strategies in economic development, transportation, and housing that will improve the quality of life of residents in both counties. The partnership promotes a more sustainable land use pattern providing appropriate employment closer to where people live and more affordable housing closer to employment in jobs-rich areas throughout the study corridor. By doing so, workers would have more opportunities to live closer to work, reducing the need for long distance interregional commuting. Centered on I-15, this two county commute corridor extends from central San Diego to the cities of Lake Elsinore, Perris, and Hemet as shown in Figure 1. Transportation is one of the three elements included in the IRP. The transportation component of the IRP develops a Strategic Implementation Plan (SIP) that will concentrate on short term strategies (5, 10 and 15 year horizon) for the I-15 corridor. The IRP Phase III consists of the following tasks: 1. Task 1: Compile and document existing Project Study Reports in the study corridor 2. Task 2: Goods movement data summary 3. Task 3: Analysis of transit priority treatments and transit lane infrastructure development 4. Task 4: Cost-effectiveness analysis and overall funding strategy This final task of the IRP Phase III is the SIP which, summarizes the analyses conducted in the prior tasks and prioritizes the proposed strategies and projects, presenting an action plan for the implementation of short term projects. Whenever possible, the SIP will also incorporate the results of the Interregional, Transit, Buspool and Vanpool and the Cost Effectiveness Studies. Figure 1 shows the study area for the I-15 IRP Phase III effort and Figure 2 shows the I-15 IRP Phase III Smart Growth and Transportation Priority Area.

The seven PSRs assembled in the report span from Lake Elsinore in Riverside County down to State Route 52 (SR-52) on the northern border of the city of San Diego. The PSRs reviewed for this study are listed as follows: Riverside County PSR for I-15 between State Route 79 (SR-79) to north of the I-15/Interstate 215 (I-215) Junction, April 2002 PSR for interchange improvements on I-15 at Railroad Canyon Road, September 2002 PSR for the I-15/SR-79 South interchange, February 2004 PSR to modify existing interchange at I-15/State Route 74 (SR-74) junction, January 2005 PSR to widen roadbeds and high occupancy vehicle (HOV) lanes on I-15, between the 15/215 split and Riverside County line, October 2007 San Diego County North I-15 Corridor PSR, between SR-52 and State Route 78 (SR-78), San Diego County, September 1998 I-15 Final Project Report, between SR-52 and SR-78, San Diego County, February 2003 However, as the Task 1 report detailed, there is a lack of planned improvement, or gap, in the middle of the corridor, as the PSR segments reported do not include the section situated between the 15/215 interchange in Riverside County south to Escondido in San Diego County, which is the area on either side of the border between the two counties. Data from the PSRs were reviewed including: average weekday peak period traffic, number of interregional vanpools, daily interregional transit ridership and peak period vehicle occupancy at the county line. The following has been identified as a result of reviewing
