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.
Action Plan for both phases
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. Participating in the 2013-14 study are representatives from San Mateo County, GGNRA, State Parks, CalTrans, and MCC.
Transportation Management Plan (TMP)
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. RFP includes scope of work and timeline.
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.
In December 2012 MCC did further investigating and reported to DPW that 4 out of 5 Hwy 1 street lights at 1st and 2nd Streets in Montara were not working. All 6 metal-pole Caltrans street lights at 7th, 8th and 9th Streets were also reported as not working.
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
Midcoast crossings, left-turn lanes, medians.
A project to complete detail design plans and permitting (not including actual construction) will begin in 2014, funded by a 2012 County Transportation Authority Measure A Congestion Management grant. A Preliminary Planning Study with design alternatives for public feedback should be available mid to late 2014. The planning & permitting process will take approximately 18-24 months.
The list of project elements comes from the concept plans of the Hwy 1 Safety/Mobility Studies: Grey Whale Cove -- Montara Beach -- Montara North -- Lighthouse -- Montara Central -- Moss Beach -- El Granada
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. In April 2014 the County Transportation Authority (TA) approved Measure A funding for design/permitting of the southern segment from HMB city limit at Alto/Mirada north to Coronado (application, MCC support).
To fund the northern segment, connecting Moss Beach and Montara via a trail connecting Carlos and Main, the County is applying to the Active Transportation Program, a state program for bicycle and pedestrian grants including Safe Routes to Schools. (MCC support)In 2013 Half Moon Bay extended their portion of the trail north to Frenchman's Creek where it crosses to the east side of the highway. A future project segment will complete their trail north to the city limits at Alto/Mirada Rd.
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/Ped Crossing - Site plans for public access/parking at north and south portals. 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.
Lighthouse area left-turn lanes
In fall 2012, CalTrans installed left-turn lanes at the lighthouse, 16th and Carlos Streets. The project was a surprise to the County and Midcoast community. It did not have a Coastal Development Permit (CDP) and did not follow the design concepts of the Highway 1 Safety/Mobility Study. The south-bound left-turn lane into little-used 16th St was created by widening pavement, increasing pedestrian crossing difficulty without providing a crossing or refuge island, and by moving the west-side fog line, reducing by half the bike/ped access along the highway over the ravine which is the only access between Moss Beach and Montara.
