The San Mateo Coastside Access Study considers access to public lands along the San Mateo County coast between Pedro Point Headlands and El Granada. The partners to the study were San Mateo County Parks, California State Parks, and Golden Gate National Recreation Area (GGNRA). The consultant team carried out an assessment of access capacity and visitor demand at primary access sites within the study area. The team considered current conditions and developed a forecast of how visitor access might change in the future. Transit needs, and shared parking and trailhead opportunities were evaluated in the context of anticipated visitor and parking demand based on 15 and 25 year forecasts and the recreation facilities type as Regional Attractors, County Attractors, or Local Attractors.
