The detailed plan for managing the projected traffic and transportation associated with the Golden State Warriors proposed Mission Bay arena, office and retail development has just been released.
The Transportation Management Plan‘s nine (9) stated objectives (and performance standards below):
- To facilitate and promote safe use of non-automobile transportation by people attending and supporting Event Center events or office and retail uses on-site
- To highlight and optimize the use of transit by both event attendees and event or daily employees
- To facilitate and maximize bicycle use by Event Center Development event attendees and event or daily employees
- To facilitate a high-quality walking experience to the Event Center Development from adjacent residences, employment locations, transit stations, and parking garages by identifying key walking routes and major street crossing locations, so that wayfinding can be provided and PCOs can be located at critical points to manage the interaction of pedestrians and vehicles during major events
- To publicize the non-traditional transportation resources existing in the site vicinity, including the Mission Bay Transportation Management Association (TMA) shuttle service and pedicab ride providers
- To maximize safety for all transportation users at key locations around the Event Center Development site and broader neighborhood during event ingress and egress
- To ensure the safe interaction of pedestrians and cyclists traveling along South and 16th Street and vehicles accessing the Event Center Development garage entries located on South Street at Bridgeview Way and on 16th Street at Illinois Street
- To facilitate the safe and efficient flow of vehicle traffic into and out of the site and throughout the Mission Bay neighborhood during event and no event conditions; and
- Under a scenario without implementation of the Muni Transit Service Plan, to maintain a stated maximum auto mode share standard of 53 percent under peak weekday event conditions (6:00 PM – 8:00 PM) and 59 percent under peak weekend event conditions (6:00 PM – 8:00 PM).
In addition to a proposed 950 parking spaces under the arena, which will be shared with the office and retail components of the development, the Warriors organization has purchased the right to use 132 additional stalls located in the parking garage at 450 South Street for their employees.
And the City has identified two off-site parking lots on Port of San Francisco lands to the south of the Event Center that could accommodate up to 1,050 additional cars.
According to the plan, “as long as the Port of San Francisco takes all necessary actions to make the land available for public parking, GSW shall: (1) make commercially reasonable efforts to negotiate with the Port of San Francisco or its designee to acquire sufficient rights for the use of such parking lot(s) through lease, purchase, or other means as necessary; and (2) (if such negotiations are successful) provide free shuttles to the Event Center from such off-site parking lot(s) that are more than ½-mile from the Event Center on a maximum 10-minute headway before and after events.”
And as part of a proposed street restriping, a total of 120 new on-street metered parking spaces will surround the arena development on three sides (South Street, Terry François Boulevard, and 16th Street). On-street spaces in the blocks adjacent to arena will likely be marked with Special Event parking signs and rates, similar to those found around AT&T Park, on designated event days.
In terms of expectations and performance, the transportation plan includes eight (8) specific measures:
- Weekday Auto Mode Share: Targeted average auto mode share should be no greater than 53 percent for weekday peak event arrivals (6:00 PM – 8:00PM).
- Weekend Auto Mode Share: Targeted average auto mode share should be no greater than 59 percent for weekend peak event arrivals (6:00 PM – 8:00PM).
- Vehicle Queuing on City Streets: Traffic entering the parking garage from eastbound 16th Street does not spill back to 16th Street or back to the 3rd Street intersection due to garage ingress.
- Vehicle Queuing on City Streets: Event traffic will not block access to the UCSF Emergency Room entrance for emergency vehicles or patients on Mariposa Street between I-280 and 3rd Street.
- Pedestrian Flows: Pedestrians do not spill out of sidewalks onto streets with moving vehicles, or out of crosswalks when crossing the street.
- Bicycle Parking: Signage is clearly visible to direct bicyclists to event valet and other bicycle parking, which has an adequate supply to accommodate a typical peak event.
- Transit Mode Share: All Muni Metro and additional shuttle passengers are able to board their transit vehicle within 45 minutes following an event.
- Good Neighbor Policy: Mission Bay TMA shuttles continue to run and maintain capacity for simultaneous neighborhood use.
And if the performance standards are not being met, the Warriors “will explore additional travel demand strategies, operational efforts, or minor redesigns” to meet the goals above.
