Build Conditions (2019) p.m. Peak-hour Traffi c Volumes 4.7.3 Loading and Service A critical component of the master planning effort was to identify measures to improve the loading and service operations. The current loading facility for the West Campus is located close to the Emergency Department and Trauma Center entrance at the Menino Pavilion, and is not large enough to allow trucks to maneuver off street (trucks currently have to back in off of Albany Street). This disrupts Albany Street vehicular and pedestrian traffic. Through the IMP planning effort, Boston University Medical Center is proposing relocating the loading across Albany Street behind the existing Power Plant when the Administration/Clinical Building is developed. This will remove trucks from Albany Street by allowing them to use BioSquare Drive from the regional roadway network. It will also remove the disruption to vehicles and pedestrians on Albany Street. Either existing tunnels beneath Albany Street will be upgraded or new tunnels will be constructed to allow distribution from the loading facility to the campus. The relocated loading facility will also accommodate the new IMP projects. This remarkable improvement will significantly improve the existing loading operations and will provide the capacity to support future growth. Figure 4-20 shows the proposed IMP campus plan with the IMP projects, BioSquare Drive connection and loading facilities. 4.7.4 Future Parking Supply and Demand The projected IMP development will add 565,000 net new square feet of building space on-campus, excluding the 48,000 s.f. for the Energy Facility, which will not generate new parking demand. Based on the BTD guidelines for this area of 0.75 to 1.0 spaces per 1,000 square feet, this floor space equates to a need for an additional 425 to 565 spaces. Peak demand is actually estimated at the higher end of this range (565 spaces) based on current on-campus parking ratio of 0.85 spaces per 1,000 s.f. At the present time, no new parking is anticipated to be added within the term of this 10 year IMP. As a result, the campus off-street parking ratio will decrease from 0.85 to 0.76 spaces per 1,000 square feet, still within BTD’s recommended range for this area. Over the years, the parking ratio for Boston University Medical Center and BioSquare has steadily decreased as development has increased. At the same time, Boston University Medical Center has employed active parking management to monitor space use, as well as a hierarchy of fees that makes the most convenient spaces the most expensive. The combination of the constrained supply and increased fees, along with transit service improvements and active demand management, has allowed the medical area to accommodate growth while limiting project-generated traffic increases. The existing 710 and 610 Albany Street garages will continue to operate as the major parking facilities for the campus, supplemented by off-site leased parking spaces as needed. Transportation 4-72 As the 10-year IMP unfolds, Boston University Medical Center will continue to actively manage both its on-campus owned spaces and its off-campus leased supply in order to meet new demand, while continually working to encourage the use of alternate modes such as transit, walking, and bicycling. In the short term, 400 existing spaces are vacant at peak today. In the longer term, the total parking demand for up to 565 spaces will be met through a combination of on-campus spaces and leased off-site facilities. As each IMP project is advanced, Boston University Medical Center will continue its parking management strategies and, if needed, evaluate off-site employee parking options to preserve the most convenient spaces for patients and visitors on the campus. 4.7.5 Transit, Pedestrian, and Bicycle Impacts The IMP projects will generate about 3,000 transit trips over the course of a day. Added transit riders, cyclists and pedestrians will use existing pathways along Melnea Cass Boulevard and the Southwest Corridor Park, as well as improved sidewalks and pathways through the campus. In the long-term, the South Bay Harbor Trail will provide a new shared use path along the outer perimeter of the BioSquare site. New transit service by the MBTA in the area will improve continue to improve transit access at the Medical Center. Transportation 4-73 N Not to scale. Source: Tsoi Kobos Associates. Figure 4-20.
