Highway 1 Studies & Issues
Transportation Management Plan
The County is developing a Comprehensive Transportation Management Plan (CTMP) to address cumulative traffic impacts of Midcoast residential development on Highway 1 and 92. Based on an analysis of traffic impacts at buildout, specific policies will be developed to offset the demand for all peak period vehicle trips generated by new residential development. The plan will evaluate expanded public transit, multi-modal travel, and programs for traffic mitigation fees on new development, and mandatory lot merger and lot retirement. Project planner is Mike Schaller.
The project has undergone a course correction since April 2015 to allow for additional analysis and report revisions. Public outreach will resume this fall.
The CTMP is a requirement of the 2012 Midcoast update to the Local Coastal Program (LCP Policy 2.53). $600,000 in County funding was initially allocated for the project which is expected to be completed in late 2016.

Highway 1 Safety & Mobility Studies
During 2009-2012 San Mateo County conducted a two-phase public participatory planning effort to develop conceptual plans to improve Highway 1 safety and mobility between Half Moon Bay and Devil’s Slide.
Midcoast Rural PDA designation abandoned
The controversial Rural Priority Development Area designation for the Midcoast was applied for in 2012 as a way to receive priority transportation funding from ABAG (Association of Bay Area Governments). Due to community objections the idea was abandoned and replaced by 5 Rural Community Investment Areas (RCIA). Read more.
Highway 1 Projects
Crossings, Raised Medians, Left Turn Lanes
Project Elements were identified by the community as near term, high priority, and are based on concept plans in the Highway 1 Safety & Mobility Improvement Studies:
6/23/15 Public Workshop presentation
4/28/15 MCC comments - minutes
Design/permitting phase is funded by 2012 County Transportation Authority grant ($1,500,000).
Highway Protection at Surfers' Beach
San Mateo County, Caltrans, and Half Moon Bay are collaborating on a project to protect the highway from erosion at Surfers’ Beach, connect a 400-foot section of the Coastal Trail, and add a stairway down to the beach over the newly installed 175-foot section of rock slope protection. The Coastal Development Permit for the coastal armoring is temporary, for a 10-year period, to allow time to implement a long-term solution to protect the highway from erosion (such as moving this section of highway).
Highway 1 Parallel Trail
This trail has long been envisioned as an east-of-highway multi-use transportation trail connecting the Midcoast communities to each other and to Half Moon Bay. The trail is expected to be completed in 4 segments.
--Northern segment (connecting Moss Beach and Montara via Carlos and Main): The County's 2014 application to the CA Active Transportation Program, was not selected (MCC support -- Staff Report). Other funding sources will be sought.
Devil's Slide Tunnel & Trail
Devil's Slide Coast website welcomes the opening of the tunnel in March 2013. The former Devil’s Slide roadway has been converted into a multi-modal segment of the California Coastal Trail, managed by County Parks, which opened in March 2014. (trail webpage)
Bike/Pedestrian Crossing - After much discussion about safety and crossing alternatives at the south portal, Caltrans moved forward with an at-grade crossing with an on-demand pedestrian crossing signal.
History of Devil’s Slide: Caltrans’ plan for a 6-lane bypass over the mountain from Pacifica to HMB Airport, and the citizen initiative for a tunnel solution.
The 1976 CA Coastal Act (Section 30254) mandates "that State Highway Route 1 in rural areas of the coastal zone remain a scenic two-lane road." For the Midcoast that applies to the area north of Montara to Pacifica, outside the urban/rural boundary created by the LCP to contain development.
