The Mission Bay Tetris Rubiks Cube Rail Freeway Challenge

Tonight the San Francisco Planning Department will present its very preliminary overview of the Railyard I-280 Boulevard Alternatives Study. I encourage you to attend if you missed the first meeting. And if you are for better rail, better pedestrian connections, and if you have concerns, or just want to support, please go and be vocal. Don’t let one voice smother the other voices in the room or in the conversation, even if we don’t all agree on something.

Where: Potrero Hill Neighborhood House, 953 DeHaro Street
When: TONIGHT, March 30, 2016 from 6-8pm

The Railyard I-280 Boulevard Study is a mouthful to say and not easy to explain in a short sentence. But I’ll give it a try: The study is looking at local and transportation networks in and around Mission Bay to build a better rail tunnel to Downtown San Francisco, create safer access in and out of Mission Bay by removing rail and freeway barriers in this growing neighborhood. In addition the study looks to consider opening up land to new housing, parks and office space.

Although much of the media attention and the resistance to this study has focused on the removal or “tearback” of 1 mile of I-280, most of the study is really about the rail tunnel and the chance to better connect Mission Bay, for both pedestrians, but even cars, into the rest of San Francisco. So if you read reports about this project and they don’t mention rail or a tunnel know that the article is only focusing on the folks screaming the loudest, and not looking at the whole picture. In fact, most of the ideas proposed in the report can be mix and matched – included or left out.

San Francisco was once a great industrial and ship building city with many factories, railyards, warehouses and drydocks, including Mission Bay. Railroad tracks once coursed through much of the eastern neighborhoods of San Francisco on its streets and onto its piers. In the 21st Century, some of these areas, have become new residential and employment neighborhoods with smatterings of warehouse and industrial uses remaining.  Most of the railroad tracks are paved over or ripped out. Now the T-Third line rolls down Third Street, and voters approved to bring rail to the heart of downtown San Francisco’s Transbay Center; currently under construction, the rail tunnel not yet funded.

With these changes comes the need to ensure that these new neighborhoods are well connected into San Francisco’s grid and not separated, as they once were when they were industrial. Likewise, reviewing the plans and financing of a new rail tunnel to Downtown is necessary to move the project forward.

San Francisco’s Planning Department is addressing these changes in and around the Mission Bay neighborhood with the Railyard I-280 Boulevard Feasibility Study. The study is looking at the three-dimensional landscape of Mission Bay with its streets and rail on the ground, freeways and building rising into the air, while water pipes and future trains run underground. The report asks how to best move people, cars, bikes, buses and trains safely and efficiently through the area while also better connecting the new neighborhood into the city through removing the historic barriers separating this former industrial from its neighbors.  

The study is also examining how to improve both local and regional connections while also seeking opportunities for new housing, open space and jobs, all the while consider the benefits and impacts of each component and the overall plan.


Before going into the details of the new RAB study, let’s review the recent planning and transportation history of the area. 

San Francisco voters passed Proposition H to “extend the Caltrain line to a new or rebuilt regional transit station in San Francisco to be located on the site of the Transbay Terminal at First and Mission Streets.”
The initiative also called for the City to pursue electrification of the entire Caltrain line, and to consider adding new stations in Bayview/Hunters Point and Visitacion Valley.
The tunnel, called the Downtown Extension (DTX), will connect the center of Downtown San Francisco with the 4th & King Station as well as all Caltrain stations at points southward.
Studies began to examine how the Caltrain Railyard might be redeveloped either through a deck or by removing the railyard altogether.
The city determined that the CA-HSR plan for San Francisco would require a street underpass/trench to grade separate street users from frequent trains, and create a very inhospitable environment for pedestrians, cyclists, and more. The underpass is also needed so cars can flow between neighborhoods without a crossing gate being down half the time for trains.

The city, in light of the grade separation challenges along 7th St, began reconsidering where a Caltrain tunnel could be built, in part to address the 16th St crossing, but also help reconnect neighborhoods and potentially straighten the tunnel to improve operations.
