The City of San Francisco has just released an official Request for Proposals (RFP) to study the feasibility and alternatives for redeveloping the 20+ acre Caltrain Depot at 4th and King Streets, connecting rail to the Transbay Center (and possibly the East Bay), and reconfiguring the terminus of I-280 in the city.
The Railyard Alternatives and I-280 Boulevard Feasibility Study will build upon the Planning Department’s 4th & King Street Railyards Study, the Caltrain North Terminal Feasibility Assessment, and past work by the Transbay Joint Powers Authority and California High Speed Rail Authority to develop a coordinated vision for the area and transportation plan for connecting the adjacent neighborhoods.
The five key components of the study:
- Potential refinements to the alignment and construction methods of the Downtown Rail Extension (DTX) to the Transbay Transit Center;
- Potential construction of a loop track from the east end of the Transbay Transit Center (TTC) allowing for future connection to East Bay and return train trips southbound;
- Potential construction of a surface boulevard in place of the elevated portion of I-280 in the area in order to facilitate the construction of the rail projects and connect the neighborhoods of South of Market (SoMa), Potrero, Moscone Center, and Central Waterfront for vehicles, transit, pedestrians and bicyclists;
- Potential consolidation and/or relocation of the 4th/King Railyard; and
- Land use responses to the above infrastructure changes, including economic effects and opportunities.
Proposals to tackle the first two phases of the project (Visioning and Concept Development and then the Refinement of Alternatives and Determination of Final Alternatives) are due at the end of February with a budget of $1.45 million and roughly two years to complete.
