Memorandum: 2525 Main Parking Analysis D:\PROJECTS\RE - 2525 MAIN STREET\PARKING ANALYSIS\PARKING 270\PARKING MEMO_REV1.DOCX 3 the transportation solutions company...parking analysis was conducted to identify the parking demand when considering the variations in parking demand among the project and Discovery Cube. The forecast parking demand for the project was calculated based on rates from ULI’s Shared Parking (2nd Edition). The rates for low- rise apartments range from 0.68 to 1.94 spaces per dwelling unit. The rates for high-rise apartments range from 1.15 to 1.52 spaces per dwelling unit. To provide a conservative analysis the higher rate of 1.94 spaces per dwelling unit were used under weekday and weekend conditions. The parking demand for the Discovery Cube was provided by data from the Science Center. It is anticipated that 60 patrons will utilize the parking lot on weekdays and 90 patrons will utilize the parking lot on weekends. Table C summarizes the forecast parking demand for the project after applying parking rates from ULI. As shown in Table C, the weekday parking demand is 584 parking spaces and the weekend parking demand is 614 parking spaces. The parking needs of individual land uses vary by hour of day. Since parking needs may peak at different times, it generally means that fewer parking spaces are required to serve a mixed-use project than if each land use has its own dedicated parking. As such, time-of- day factors for weekdays/weekends were applied to the forecast parking demand to develop the total shared parking demand. The time- of-day factors for the proposed project are based on Land Use “Residential” from ULI’s Shared Parking (2nd Edition). The time-of-day factors for the Discovery Cube are based on data provided by the Science Center. The time-of-day factors for weekdays were applied to the parking demand for each land use to develop the shared parking demand. The shared parking demand on weekdays is illustrated in Table D. As shown in Table D, the total peak shared parking demand on weekdays is 571 parking spaces. Given the parking supply of 719 parking spaces, it is anticipated that there will be a surplus of 148 parking spaces on weekdays. The time-of-day factors for weekends were applied to the parking demand for each land use to develop the shared parking demand. The shared parking demand on weekends is illustrated in Table E. As shown in Table E, the total peak shared parking demand on weekends is 601 parking spaces. Given the parking supply of 719 parking spaces, it is anticipated that there will be a surplus of 118 parking spaces on weekdays. The Discovery Cube hosts an event each year called Bubblefest that will draw higher than normal patrons. A shared parking analysis on weekdays and weekends was conducted for the Bubblefest. It is anticipated that 200 parking spaces will be used on weekdays and 200 parking spaces will be used on weekends during Bubblefest. The shared parking demand for the Bubblefest on weekdays is illustrated in Table F. As shown in Table F, the total peak shared parking demand on weekdays is 711 parking spaces. Given the parking supply of 719 parking spaces, it is anticipated that there will be a surplus of 8 parking spaces on weekdays. The shared parking demand for the Bubblefest on weekends is illustrated in Table G. As shown in Table G, the total peak shared parking demand on weekends is 711 parking spaces. Given the parking supply of 719 parking spaces, it is anticipated that there will be a surplus of 8 parking spaces on weekdays. Conclusion. The parking supply required for the project using parking rates from the SAMC is 779 spaces. Since the parking requirements in the SAMC are over 20 years old, Translutions conducted surveys at two similar facilities currently in operation. The peak parking demand was observed to be 1.354 spaces per unit. Using the parking demand rates from empirical data, the project parking needs are forecast to be 366 spaces. The project will include 539 parking spaces, which is approximately 32% more than the number of spaces forecast based on empirical data. A shared parking analysis was conducted on weekdays and weekends for the project and Discovery Cube. The total peak shared parking demand on weekdays is 571 parking spaces. Given the parking supply of 719 parking spaces, it is anticipated that there will be a surplus of 148 parking spaces on weekdays. Also, the total peak shared parking demand on weekends is 601 parking spaces. Given the parking supply of 719 parking spaces, it is anticipated that there will be a surplus of 118 parking spaces on weekdays. The shared parking demand for the Bubblefest on weekdays is 711 parking spaces. Given the parking supply of 719 parking spaces, it is anticipated that there will be a surplus of 8 parking spaces on weekdays. The shared parking demand for the Bubblefest on weekends is 711 parking spaces. Given the parking supply of 719 parking spaces, it is anticipated that there will be a surplus of 8 parking spaces on weekdays. 2-535
