The Salesforce Transit Center features a public 5.4-acre rooftop park. The 1,400 foot long elevated park has a wide range of activities and amenities, including an outdoor amphitheater, gardens, trails, open grass areas, and children’s play space, as well as space for a future restaurant. In addition to being a generous amenity for the quickly developing Transbay neighborhood, the rooftop park doubles as a “green roof” for the transit center, one of many environmentally-friendly building features. A landscaped green roof, also known as a “vegetative” or “living” roof, offers significant environmental benefits. It shades much of the ground-level sidewalk when the sun is strongest and provides biological habitat for flora and fauna and public open space for visitors. It also acts as insulation for interior spaces, moderating heat build-up in warm weather and retaining heat during cooler weather. Unlike asphalt paving or dark colored roofing surfaces, planting on the green roof cools the surrounding environment and improves air quality by acting as a carbon sink. As a biological organism itself, the park helps capture and filter the exhaust in the area and helps improve air quality in the neighborhood. Just over a quarter mile long, the park design includes active space allowing organized events like concerts and fairs along with quiet areas where visitors can relax in informal natural settings. The vibrant plaza located in the center of the park receives the largest influx of visitors from the building’s main escalators and elevators which connect to the ground level. Plenty of seating and daily events and activities are offered on the main plaza. The park’s western end features an amphitheater and stage for programmed performances. Botanic displays and open lawn areas allow visitors to enjoy the park. Children also find places for active and dynamic exploration. These areas fit seamlessly into the overall park plan and contain gardens, water features and other elements that offer varied perceptions and experiences for the young and young at heart.

The bus deck level of the transit center is located two levels above the ground level. The bus deck is designed as a loop that surrounds a central passenger waiting area. Buses load and off-load passengers from this central island. The bus deck level connects to a bus ramp at the western end of the transit center to the Bay Bridge.

The transit center’s bus deck level is operated by AC Transit to service the East Bay.

Muni also provides service to Treasure Island from the bus deck and Greyhound operates there.

The second floor of the transit center includes administrative offices and retail space.

The ground level serves as the primary circulation hub of the transit center. It features a Grand Hall with a prominent Light Column allowing natural daylight into the building. The main entrance off Mission Street also includes Clipper machines, interactive digital displays, and the main escalators and elevators.

Space for retail will be provided along Natoma and Minna streets.  The western end of Natoma Street will provide space for service and maintenance as well as for the Transit Center’s loading dock.  The street level bus plaza is located at the eastern end of the building between Fremont and Beale streets, serving Muni and Golden Gate Transit with SamTrans buses nearby.

The lower concourse level will serve as the passenger connection between the ground floor and train station platform. Space will be provided along the public concourse for retail, ticketing and bike storage.

The train station platform will be located two levels below the ground level. It will contain three passenger platforms that will accommodate six train tracks for Caltrain and California High-Speed Rail.
