Highway 1 Studies & Issues
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.
Transportation Management Plan
Connect the Coastside is a Comprehensive Transportation Management Plan that will identify programs and improvements along Hwy 1 & 92 to accommodate the Coastside’s future transportation needs as it grows toward build-out. The technical study will coincide with broad public outreach to ensure that the final Plan reflects the unique character and vision of local residents and businesses. The online Virtual Workshop is open for your ideas.
The Comprehensive Transportation Management Plan 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 mid-2015. Scope of work and timeline.
Midcoast Parking Study
The Action Plan for implementation of the Highway 1 Safety & Mobility Studies calls for a parking study to be completed before more detail planning of beach and trailhead parking lots in the Midcoast, with the goal of sharing and limiting the number of new parking lots. San Mateo County, GGNRA, State Parks, and CalTrans are collaborating on this 2013-14 study.
Highway 1 street lighting issues
In 2012 Supervisor Horsley exchanged letters with Caltrans asking for improved street lighting along Highway 1 in downtown Moss Beach, for pedestrian safety reasons (4/26, 5/16, 7/16, 9/20). In June 2012 the MCC did a Moss Beach Hwy 1 lighting survey which revealed about half the lights were burned out. MCC reported this to Dept of Public Works (DPW) and bulbs were replaced. DPW does not check street lights, but depends on residents to report outages.
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
Highway 1 Traffic and Safety Improvements
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: Grey Whale Cove - Montara North - Central - Lighthouse - Moss Beach - El Granada
Proposed design alternatives will be refined with public feedback.
Design and permitting phase of the project 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.
