Abrams Associates TRAFFIC ENGINEERING, INC.Page 7 of 8 – 2114 E. 1st Street Parking Demand Analysis CONCLUSIONS The proposed project qualifies as a transit oriented development due to its close proximity to a major transit stop where two major bus routes intersect. While the applicant is expecting to open discussions with OCTA about increasing the frequency of bus service near the project site, the project will not rely on this to achieve alternative transportation goals. To ensure the project fully qualifies as a transit oriented development the project is also proposing to provide residents with private shuttle service to the Santa Ana Regional Transporation Center with 15 minute headways. If the City were to allow the applicant to provide 0.5 spaces per unit, as specified by A.B. 744, the parking required for the project would theoretically be 326 parking spaces. Please note this includes the 50 spaces required for the retail uses. The parking demand can also be estimated based on the 4th Edition of the ITE Parking Generation Manual. Since the project is two blocks from a major transit stop and will be providing free shuttle service to the SARTC, the proposed project would be expected to have a 23% reduction to the ITE parking demand.1 In addition, an additional reduction to the ITE forecasts can be applied due to the fact that the entire project would be restricted to residents making 60% or less of the Area Median Income (AMI). The City of San Diego’s 2011 Affordable Housing Parking Study found that parking demand for affordable housing projects is about one half of typical rental units in San Diego and almost half the units surveyed had no vehicle. However a more conservative esimate comes from the 2016 survey of affordable housing sites conducted by the City of Los Angeles. This study determined that the number of vehicles generated by affordable housing projects is about 40% of what is generated by comparably sized market rate projects. Using the assumptions above the residential portion of the project is forecast to have an unadjusted peak parking demand of 349 vehicles. Including the 50 spaces required for the retail space would increase the forecast total peak parking demand for the project to 399 parking spaces. Please note that if it were conservatively assumed that all the affordable housing sites surveyed in the Los Angeles study also had excellent transit access (and the separate reduction for transit access was eliminated from the parking calculations) then the project would have a forecast average peak parking demand of 504 vehicles. Based on the proposal to accommodate this demand with an on-site parking garage with 620 parking spaces our conclusion is that no parking impacts to the surrounding roadways or properties in the area would be anticipated. 1-44
