Western SoMa Neighborhood Transportation Plan

Western SoMa streetscape


We have completed the Final Report, which was adopted by the Transportation Authority Board in March, 2012.


The Western SoMa neighborhood, defined generally as the area between 4th and 12th Streets and Howard and Townsend Streets, has been the focus of a community plan process that envisions land use and transportation changes to improve livability in the neighborhood while preserving its historical character. Created through a multi-year community process led by the Western SoMa Task Force, the Western SoMa Community Plan provides policy recommendations and concepts for improving pedestrian, bicycle, and transit conditions. The Community Plan is currently in the adoption process.

To support implementation of the Community Plan, the Transportation Authority conducted a Western SoMa Neighborhood Transportation Plan (NTP) process. The NTP seeks to move selected improvement ideas from the Community Plan to implementation-ready status by providing cost estimates, conceptual designs, and other relevant project development work.

Using a technical assessment and input from the community, the Study has developed conceptual designs for improvements to three of Western SoMa's alleys for traffic calming and streetscape improvements, including mid-block crossings of the numbered streets, including Minna and Natoma between 7th and 9th Streets, and Ringold between 8th and 9th Streets.


The study team sought public input throughout the Study, in particular to seek input on the selection of preferred transportation projects, and in refining conceptual designs for the preferred transportation projects. Public involvement activities included regular consultation with the Western SoMa Community Plan Task Force, an appointed body who has also guided the development of the Community Plan. In addition, activities such as public meetings, online surveys, storefront charrettes, and door-to-door outreach were all utilized to solcit input. Based on these activities, the team heard several key mesages which have been incorporated in the Study recommendations, as described in Chapter 3 of the Final Report.


Follow the links below to see conceptual plans for the improvements recommended to Minna, Natoma, and Ringold:


After completion of the plan, the proposed improvements will undergo a typical project development process, including environmental review, detailed design and engineernig, competition for funding and construction. Conceptual cost estimates for the proposed improvements have been developed, and total between $2.4 and $5.7 million. The improvements identified through this study are expected to be competitive for multiple funding sources, including: the One Bay Area Block Grant, Proposition AA, Safe Routes to Transit, the Proposition K Sales Tax, the Federal Transportation Enhancements program, the Transportatio Fund for Clean Air, and the Lifeline Transportation Program. There is also the possibility of private contributions. More detail on implementation considerations and next steps are presented in Chapter 5 of the Final Report.
