Southline Development

30 Tanforan Ave, South San Francisco





Project Description

The project is located at the edge of City of San Bruno and includes improvements that will modify streets within San Bruno City limits. The project proposes:


  • Beautification of Tanforan Avenue which serves as an access road for San Bruno residents
  • Connection of the Centennial Way Trail to San Bruno's planned Huntington Cycle Track improvements
  • A new intersection at Huntington Avenue and Sneath Lane which provides bicycle, pedestrian, and vehicular connectivity to South Maple Avenue and Southline Avenue (new) within City of South San Francisco

Additionally, the project proposes eight office / R&D buildings, parking garage, below grade parking, site amenities, open space and landscaping on a 26-acre site within South San Francisco. City of South San Francisco is the lead agency responsible for processing the approvals for this project.
