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.
Transportation Alternatives (draft report April 2015)
The CTMP is a requirement of the 2012 Midcoast update to the Local Coastal Program (LCP Policy 2.53). In December 2013 the Board of Supervisors approved $500,000 to fund the project, which is scheduled for completion early 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
At-Grade 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:
Preliminary Planning Study - attachments (2/23/15)
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 the design and preliminary engineering for a project which would include the following components:

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.
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.
