CMIA SUPPLEMENTAL APPLICATION INFORMATION Los Angeles County Metropolitan Transportation Authority INTERSTATE 10 CARPOOL LANE FROM PUENTE AVE TO ROUTE 57 DESCRIPTION OF CORRIDOR The San Bernardino Freeway (I-10) is a national east-west interstate freeway that provides access to the Los Angeles Central Business District from the San Gabriel Valley, Riverside and San Bernardino Counties. I-10 experiences severe congestion daily as it carries substantial traffic volumes. High Occupancy Vehicle lanes (El Monte Transitway) are in operation from downtown Los Angeles to I-605. A fully funded HOV lane project to extend the HOV lanes will begin construction in 2008 from I-605 to Puente Avenue moving to the western end of the gap 2.2 centerline miles to the east. HOV lanes exist from Route 57 (the eastern end of the gap) to I-15 in San Bernardino County. PROJECT DESCRIPTION This project is one of two projects (Puente Ave. to Citrus and Citrus to Rte. 57) that will extend the existing I-10 High Occupancy Vehicle (HOV) lanes from Rte. 605 to Rte. 57 in Los Angeles County. This project will construct 18 lane miles (9 miles in each direction) of concurrent flow HOV lanes and complete a significant nine-mile gap on the best performing HOV lanes corridor in Southern California. PROJECT COST CMIA Request: $365,000,000 Total Cost: $365,000,000 PROJECT BENEFITS The proposed improvement to provide 18 lane miles of concurrent flow HOV lanes (9 miles in each direc- tion) will complete the remaining HOV lane gap in the corridor. The immediate impacts of the project include the reduction of congestion and congestion related accidents in the corridor (especially during peak periods). Long-term benefits of this project will include the formation of new carpools and increased transit ridership as a complete HOV facility will exist from San Bernardino to downtown Los Angeles. With current occupancy requirements at 3 persons per vehicle (This requirement is for peak hours only and ends at I-605. Occupancy requirement is 2 persons per vehicle from I-605 to I-15 in San Bernardino County.) and with extensive transit service on the existing facility during the peak traffic periods, the existing HOV lanes carry more than four times the number of people carried on a mixed-flow lane. There are two segments to this project and the benefits are divided between the Puente Ave. to Citrus seg- ment and the Citrus to Route 57 segments.

In LA County, it crosses several other freeways and significant north/south arterials. The HOV lanes gap closure will provide a continuous facility that crosses all these freeways and arterials while providing additional lanes to ease existing freeway congestion. The HOV lanes will provide more reli- able travel times than the heavily congested mixed-flow lanes. Connectivity The major traffic generators along the I-10 corridor from Downtown LA to the County Line include: • County USC Medical Center, Cal State University Los Angeles, Cal State Polytechnic University Pomona, Mount San Antonio College, Claremont Colleges, Pomona Fairplex, Eastland and Plaza at West Covina Shopping Centers, County USC Medical Center • Major Park and Ride facility at El Monte Transit Station with direct HOV connectors for buses and several minor facilities e.g., Del Mar Avenue. This corridor lacks nearby major parallel east-west arterials that span significant lengths of the 32 mile long corridor. As the freeway crosses a dozen jurisdictions on its path to the County Linen, a continuous HOV facility can provide much needed HOV connectivity. Transit The I-10 HOV lanes, with service provided by Metro and Foothill Transit, has the highest bus ridership on an HOV facility to the El Monte Transit Station and points east than any other freeway in Southern California. Foothill Transit plans to initiate express bus service from Montclair to Downtown Los Angeles in spring 2007 and will utilize the entire HOV lane facility. The HOV lanes’ effectiveness will be enhanced with Foothill Transit’s plans for two inline bus platforms within the project limits. Air Quality and Greenhouse Gas Emissions The I-10 HOV Project is included in Metro’s 25-Year Long-Range Transportation Plan. The plan models the collective benefits of the county’s multi-modal transportation system investments to determine the overall air quality improvements and emissions reductions. The I-10 HOV Project combined with Metro’s multi-modal investments will result in air quality and green- house gas emissions reductions of approximately 50% by the year 2025. This is significant as Los Angeles has one of the worst air quality rankings in the nation and, as the most populous county in the nation, is a significant greenhouse gas emitter. The I-10 HOV Project will be leveraged with other multi-modal invest- I-10 HOV, Puente Ave. to Rte. 57 Page CMIA SUPPLEMENTAL APPLICATION INFORMATION Los Angeles County Metropolitan Transportation Authority ments including transit-oriented mixed-use development in this highly congested corridor to ensure that Los Angeles achieves a more sustainable transportation system. Multi-modal Corridor Improvements Investments Caltrans and local jurisdictions through coordination with the Los Angeles County Department of Public Works, are participating in the Regional Integration of Intelligent Transportation Systems (RIITS) Program of Metro to seamlessly exchange freeway and arterial traffic and transit information with local agencies, traf- fic/transit management agencies and traffic information purveyors. The project will incorporate a fiber optic communications backbone, CCTV, CMS, replace loop detectors, and provide ramp metering. Also, all major arterials and collector roads in the corridor are being signal synchronized and networked with planned Transportation Management Centers. Mitigating the Project Risks The Project was approved in 2002 with a Mitigated Negative Declaration/Finding of No Significant Impact and will only require updating as design efforts are initiated. The approved cross section was minimized so as to require minimal right of way. With a relatively low number of required full takings, the right-of-way process should be streamlined. Construction costs were recently updated and the rate of construction cost escalation has slowed during the last 6 months. The Project has the support of all local jurisdictions along the corridor, and the COG has created a task force of elected officials to monitor and expedite solutions to transportation issues in the corridor. Economic Development Benefits Construction of the I-10 HOV lanes from Puente Avenue to SR-57 will bring substantial economic benefits to Los Angeles County and the state. The reduction in congestion-related costs it will facilitate will make the region more competitive relative to the rest of the country and the world. Economic projections made using the REMI model indicate this project will provide the following regional benefits in the year 2030: • The creation of an additional 2,100 jobs; • An increase of $420 million (2007 dollars) in Gross Regional Product; • An increase of $190 million (2007 dollars) in real, disposable personal income; and • A $78 million (2007 dollars) boost in regional exports. Corridor Management Approach Caltrans and Metro are in the process of developing a corridor management plan (CMP) on all corridors for which improvements are submitted for funding from the Corridor Mobility Improvement Account Program (CMIA) to ensure a coordinated, multi-modal, congestion management approach. Caltrans District 7 is committed to prepare CMPs using a multi-disciplinary and multi-functional approach, including but not limited to, representatives from district traffic operations, planning and maintenance. Participation of other functions such as design, program-project management and environmental is recom- mended based on the corridor. Regional agencies, congestion management agencies and modal operators will be involved through all stages of plan development. This effort will be coordinated with Metro’s ITS program (see CMP description and ITS project description for more details). I-10 HOV, Puente Ave. to Rte. 57 Page PROJECT #3: I-10 BUSWAY EXT.
