California Park, California
This neighborhood, located in an unincorporated area of the County, incorporates the area north of San Quentin. Marin Sanitary Service is the largest tenant in the area, and the single-track train tunnel formerly owned by Northwestern Pacific Railroad runs through the hill to Larkspur has been closed for several decades, though a large controvery is ongoing whether to re-open the tunnel for bicycle/pedestrian use[1] and/or to pass a bond that would provide funding to create the Sonoma-Marin Area Rail Transit (SMART)[2]., has some development potential remaining on the Scheutzen parcels.
