Caltrain Grade Separation

Project Description
Caltrain expects to begin construction of the San Bruno grade separation project in fall of 2010. The project will eliminate four street level railroad crossings in San Bruno by lowering San Bruno, San Mateo and Angus Avenues, while raising the tracks. A new elevated Caltrain station is planned between San Bruno and San Mateo Avenues to replace the existing station at Sylvan Avenue. Pedestrian underpasses will be built at Scott Street, Euclid Avenue and Sylvan Avenue. Streets and sidewalks, including those at Posy Park, will be improved.

The grade separation project will bring a unique opportunity for new transit oriented development and improvements to pedestrian and bicycle safety in the area.  The City of San Bruno is undertaking a comprehensive planning process for the City’s downtown and transit corridor areas, with a special emphasis on the new Caltrain station area.  This specific plan is building on the City’s recently updated General Plan, which established a framework for transit oriented development in the new station area.  For additional information on the Downtown and Transit Corridors Plan, please visit the project website: Info Button.

History of Public Review
Starting in 2000, the City Council and concerned citizens began looking at ways to improve safety at the San Bruno Avenue crossing. An Ad Hoc Committee was formed, which met with representatives from the (Caltrain) Joint Powers Board during 2001. Through this process, five alternatives were developed.

In 2002, the City Council adopted a resolution to support the grade separation and selected Alternative 5 as the preferred alternative. The Council also took action to form a Citizens Advisory Committee (CAC) to work with JPB and refine details of Alternative 5. The 15 members of the CAC participated in over ten meetings. The result of this process was a Project Study Report, dated July 7, 2003.
