San Mateo County
Snow sidewalk clearing is not a regular concern in unincorporated San Mateo County's Mediterranean coastal climate, and the County has no dedicated snow-clearance ordinance. On the rare occasions of snow at Skyline Ridge or upper La Honda/Kings Mountain elevations, Caltrans clears State Routes 35, 84, and 92, while property owners are generally responsible for keeping their own driveways and sidewalks (where they exist) passable. Streets & Highways Code §§5610-5618 gives local agencies general authority over abutting-property sidewalk maintenance.
