The project is also proposing to meet the major transit stop requirement by providing a shuttle service to the Santa Ana Regional Transit Center. The Santa Ana Regional Transportation Center (SARTC) is a major transfer center that provides access to regional Amtrak and Metrolink rail services as well as intercity and interstate bus transportation. The shuttle is planned to include service during the weekday peak commute hours with a maximum headway of 15 minutes using a 20 -passenger shuttle bus. Other than the project itself, the shuttle would include the following stops to serve residents: 1$' Street at Cabrillo Park Drive 18t Street at Lyon Street 15' Street at Grand Avenue 1 st Street at Standard Avenue Santa Ana Boulevard at Santiago Boulevard (The Santa Ana Regional Transit Center) Grand Avenue at Santa Ana Boulevard Based on data from MTC's travel survey for projects within 1 mile of a train station, during the peak commute hours the project would be forecast to generate approximately 105 transit trips. However, please note that that it is forecast that approximate three quarters of these trips would be expected to use the planned shuttle service and the other 25% of these transit trips would be made via existing public transit in the area. Again, please note that there are public bus stops located less than a block from the site. With the addition of the shuttle service to the SARTC the project will meet the definition of a transit oriented development (subject to City approval) and, as such, a reduction in the parking demand from the project would be forecast to occur. Based on a detailed analysis of 12 large TOD housing projects the parking demand for the proposed project, when compared to a project without any major transit stops nearby, would be expected to be reduced by a minimum of 23%. Therefore, the addition of the shuttle service is estimated to equate to a minimum reduction in parking demand of approximately 150 parking spaces.' In addition, the detailed surveys of TOD housing projects have found that the peak parking demand recorded at TOD sites has been found to be a minimum of 45% less than the peak parking demand rates for apartments published by the Institute of Transportation Engineers (ITE).2 For the proposed project (ITE Land Use Code 222) the peak parking demand for non-TOD sites is 1.37 vehicles per unit. Therefore, based on surveys of similar TOD apartment projects the parking demand is forecast to be approximately 0.62 vehicles per unit, meaning the parking demand for the residential portion of the project could reduced for transit access by as much as 414 spaces (i.e. the Statewide Transit Oriented Development (TOD) Study Special Report — Parking and TOD: Challenges and Opportunities, Business, Transporation, and Houiing Agency of the Calfiornia Department of Sacramento, CA, February, 2002. x Parking Generation at Transit -Oriented Developments: Five US Case Studies, Reid Ewing, College of Architecture and Planning, Univerisyt of Utah, Salt Lake City, UT, November 2016. 65C-40
