The rendering above (top) depicts the design of the future Chinatown Station. Construction is expected to be completed in 2017. The building currently at this site (bottom) will be demolished to make way for the new station.

We have exciting news about the Chinatown Station property and contract. The San Francisco Municipal Transportation Agency (SFMTA) has completed acquisition of the building at 933-949 Stockton Street, the site of the future Chinatown Station, and work has begun that will secure the building and enhance its appearance until it is demolished.

A decorative vinyl wrap (shown below) will be applied along Stockton and Washington streets to protect the vacant building from vandalism and enhance its appearance. The wrap will feature renderings of the future Chinatown Station design, a Chinese mural provided by the Chinese Historical Society of America and artwork provided by students from the Chinatown YMCA. The wrap will remain in place until the building is demolished later this year.

Work to apply the vinyl wrap, remove signage and secure the building began today and is expected to continue through mid-March. While work is in progress, a temporary walkway will be installed to ensure pedestrian safety. You can find more information about this work in our construction notices, which are available in English and Chinese.

During the acquisition process, the SFMTA aided in the relocation of 19 residential households and eight commercial businesses. All of the residential tenants have moved to new residences, including four households that purchased new homes. The eight commercial tenants have been relocated, and six of them have relocated nearby.

The final design of the Chinatown Station has been completed, and the contract for station construction is scheduled to be released for bid by the end of February.

More details can be found in this press release from the SFMTA.
