Upgrade The Drake: Sir Francis Drake Blvd Rehabilitation (Highway 101 to Town of Ross)

  • The County has received funding to rehabilitate and make improvements to Sir Francis Drake Boulevard between Highway 101 and the Ross town limits. The project process has involved analysis of existing conditions, public outreach, identification of potential improvements, and selection of a preferred alternative, followed by finalized design and is now in the construction phase.
  • Once completed, the project will provide public safety improvements along the 2.2 mile corridor, including pedestrian safety and access, vehicle safety and traffic flow.
  • The 18-month construction project began in Summer 2020 and is expected to be completed by Winter 2021.

Lucas Valley Road Curve Realignment

  • The project will realign the hairpin curve on Lucas Valley Road at milepost 5.08 in West Marin. The important public safety project will make significant improvements to the turn, which has been the site of several trucking accidents over the years.
  • The estimated $2.25 million project is anticipated to begin construction in mid-summer 2021 and is expected to be completed in winter 2021.
  • The project is partially funded by a $1 million Federal Highway Safety Improvement Program (HSIP) grant. The remaining funding will come from the County’s Road and Bridge Rehabilitation Fund.
  • To improve safety and realign the hairpin turn, a retaining wall will be constructed and the roadway will be shifted eastward to alleviate the curve. The project also includes improvements to storm drain infrastructure, installation of safety guardrail and new asphalt pavement.
  • It is anticipated that there will be traffic impacts associated with the planned work. Traffic control measures will be in place and advance notice will be given of any closures.

Upper Lucas Valley Northern Region Paving & Microsurfacing

  • The estimated $1.5 million project will take place on residential roads located in the Upper Lucas Valley neighborhood.
  • General concrete work and preparations for the roadway resurfacing and Microsurfacing project are underway, including on sidewalks, curbs and gutters, ramps, and storm drainage on select roads listed above. This prep work is expected to last through end of May 2021.
  • At the end of May, the roadway resurfacing project is expected to begin and will be conducted in 2 phases. The main operation will focus on paving and microsurfacing.
  • Improvements for the project include full width grinding, road base failure repair, road resurfacing, microsurfacing of select roads, minor drainage improvements, repair of concrete curb & gutter, sidewalks, and accessibility curb ramps; and traffic striping and marking.
  • The construction is expected to take approximately 3 months to complete. The work will take place during the daytime hours with traffic control measures. Because some of the roads listed above are too narrow to accommodate construction equipment with one lane of alternating traffic, it will be necessary for the contractor to temporarily close portions of roads during working hours for microsurfacing and for placing asphalt. Advance notice will be given to residents to help minimize any inconveniences.

2021 Road Sealant Project

  • The project consists of the application of a pavement preservation treatment (microsurfacing) on 9.5 centerline miles of County-maintained roadway in the North Novato, Green Point and Indian Valley neighborhoods of Novato and the California Park neighborhood of San Rafael.
  • The estimated $400,000 project is expected to begin construction in May 2021 and is anticipated to take eight weeks to complete.
  • The work will take place during the daytime hours with traffic control measures. Because some of the roads are too narrow to accommodate construction equipment with one lane of alternating traffic, it will be necessary for the contractor to temporarily close portions of roads (during working hours only) during the sealing operations. Advance notice will be given to residents to help minimize any inconveniences.

Bayside Park ADA Improvement Project

  • Bayside Park construction is underway and is expected to be completed in July 2021. The park is closed during construction.
  • Due to age and damage from root uplift, the park was deemed no longer code compliant for accessibility.
  • The entire park will be refurbished including grading of many areas of the park, replacement of all paths, benches and trash/recycling receptacles. Nearly all landscaping will be replaced, including new trees that will be placed to prevent future root uplift of paths, and drought tolerant, heavily native plants to better reflect our environment.
  • The approximately half acre park also provides access to the San Rafael Sanitary District’s pump #24, so a vehicle path is included as part of the design.
  • As a condition of the original 1971 San Francisco Bay Conservation and Development Commission (SFBCDC) permit, the curb running along the entire park will become a no parking zone in order to provide a dedicated bike lane. This parking/bike lane change will become effective as soon as construction is complete and the park reopens.
  • In collaboration with the City of San Rafael, the County of Marin is developing conceptual plans for potential future efforts on this stretch of roadway which will facilitate restoration of on-street parking and will likely include bike lane improvements and traffic flow changes, pedestrian crossing and signage modifications. We anticipate introducing concepts to the community in the near future and look forward to receiving community feedback on these proposed improvements.

Dillon Beach Retaining Wall

  • A retaining wall will be constructed approximately 0.25 mile west of Elephant Rock on the north side of Dillon Beach Road to abate further ground movement at this location. As the project is in design, the length of the wall is yet to be determined and the estimated construction cost is still unknown.
  • As this segment of Dillon Beach Road is the only route to the township, the County considers the new retaining wall a high priority. The project is expected to enter construction late summer 2021 and be completed before winter 2021 storm season.

Marin City Pedestrian Improvement Project

  • The County has been awarded a Lifeline Transportation Program grant by the Transportation Authority of Marin to make pedestrian improvements at the intersection of Drake Avenue and Cole Drive in Marin City.
  • The project plans to provide new sidewalks, curb ramps, crosswalks, and a rapid-flash warning beacon.
  • The project is in the design phase and is targeting a fall 2021 start date for construction.

Lucas Valley Road Slide Repair at milepost 3.92

  • The project involves installing an approximately 116-foot pile wall to stabilize the roadway, remove and replace portions of an existing culvert and rebuild approximately 150 linear feet of roadway.
  • Approved for Federal reimbursement from the Federal Highways Administration’s Emergency Relief Program.
  • It is anticipated that the work to occur during standard work hours and will require a lane closure for duration of the project, which is 40 working days.
  • Timeline for construction is dependent on Caltrans review process. Current estimate is a late summer 2021 construction start date.

Fairfax Bolinas Road Slide Repair at milepost 5.73

  • The project will reconstruct approximately 120 feet of roadway where a slide has reduced the structural integrity of the roadway.
  • The effort will include an earthwork roadway repair consisting of a shear key and buttress fill, as well as subsurface drainage. Additionally there will be asphalt resurfacing, shoulder backing and striping.
  • Construction activity is expected to begin in Spring/Summer 2022.

HSIP Guardrail Replacement

  • The project will consist of replacing nonstandard guardrails at 13 locations throughout Marin County, with a total installation of approximately 4500 linear feet of guardrail. The targeted sections are located along Tomales Petaluma Road, Marshall Petaluma Road, Point Reyes Petaluma Road, San Pedro Road, and Panoramic Highway.
  • The work proposed will replace guardrail end treatments, as well as existing guardrails that are lower than the minimum guardrail height, and guardrails that have been damaged.
  • Construction is expected to begin in summer 2022. This project is funded in part by a California Highway Safety Improvement Program (HSIP) grant.

HSIP Signal Enhancements

  • The County of Marin has proposed traffic signal safety enhancements at 51 signalized intersections throughout unincorporated Marin County and in 11 incorporated cities and towns. The project is a joint effort with the County of Marin acting as the lead agency coordinating with the cities and towns.
  • The proposed project safety improvements include: upgrading signal heads to 12" LED signal heads, adding signal head backplates, adding pedestrian countdown heads, adding audible pedestrian signals at pedestrian push buttons, updating signal hardware to incorporate Lead Pedestrian Intervals at crosswalks, and adding video or advanced detection loops for advanced dilemma zone detections. There are no below ground excavation or earth disturbance activities associated with any of the proposed improvements.
  • The upgrades have the potential to improve public safety by reducing the incidence and severity of collisions at the intersections.
  • The estimated $2.8 million budget is being funded by a California Highway Safety Improvement Program (HSIP) grant. Construction anticipated to begin Summer 2022.

HSIP Panoramic High-Friction Skid Resistant Treatment

  • The project will install a high-friction skid resistant pavement on approximately 4 miles of Panoramic Highway, from milepost 4 to milepost 8.
  • The work includes widening of the roadway shoulder where feasible to provide a safety edge on the pavement.
  • Funded in part by a California Highway Safety Improvement Program (HSIP) grant, the project is in design and the construction phase is expected to begin by early 2023.

Frank Valley Road Improvements near Muir Woods National Monument

  • The project is being led by the Federal Highway Administration (FHWA).
  • Frank Valley Road/Muir Woods Road is a two-lane roadway that provides connectivity between Muir Beach, Mill Valley and the park lands. For reference, Frank Valley Road becomes Muir Woods Road north of Redwood Creek Bridge near the National Monument (see map).
  • The County has been approved for a $5.2M Federal Lands Access Program (FLAP) grant for the resurfacing and rehabilitation of 2.48 miles of Frank Valley Road from the Muir Woods National Monument to State Route 1 in Muir Beach. The stretch of Frank Valley Road that is being rehabilitated is the only roadway providing access to the Muir Woods National Monument from the south. This project will improve both safety and function for 2.48 miles on the roadway through pavement rehabilitation, roadway shoulder stabilization, drainage improvements, roadway widening, and improved signage and striping. The road improvements will maintain the characteristics of a local, two-lane roadway to minimize environmental impacts to Redwood Creek.
  • In conjunction with the road improvements, an additional $2.5M grant will be utilized to replace and realign Redwood Creek Bridge, south of the National Monument entrance, as it has been classified as structurally deficient, functionally obsolete and in need of replacement. The proposed new bridge alignment will meet current road geometry and safety standards.

Muir Woods and Frank Valley Roads Parking Restrictions & Muir Woods National Monument Reservations

  • The Marin County Department of Public Works (DPW) is responsible for aspects of transportation in the area around the park and is working on behalf of residents affected by park traffic. This is part of a larger, long term sustainability initiative/project being conducted by the National Parks Service (NPS). 
  • DPW is working with NPS on parking restrictions along Muir Woods and Frank Valley roads, and parking restriction associated with the reservation system for Muir Woods National Monument. A 2015 Memorandum of Understanding detailed the management of parking, access, and implementation of a NPS reservation system.
  • In January 2018, NPS implemented a parking reservation system that supports management of visitation to levels that meet park goals for safety, natural resource preservation, visitor experience, and public access. The reservation system provides a long-term measure that will allow the park to work with visitors in advance of their arrival so that congestion, and its related impacts, can be minimized and the quality of the experience enhanced. NPS has also enhanced the Muir Woods Shuttle program to support access to the national monument. Parking restrictions such as traffic barriers, bollards and no parking zones have been implemented along Frank Valley Road and Muir Woods Road. Additional restrictions may be initiated to support the NPS reservation system.
  • NPS and the County of Marin have committed to a phased elimination of parking outside of the monument's boundaries. The NPS is currently working on a Sustainable Access Project (SAP) within the park to redesign and reorganize parking in Muir Woods. More information on the project can be found on NPS' project page and additional information on NPS' other projects can be found on their Redwood Renewal program page.

Sir Francis Drake Boulevard Improvements in Point Reyes National Seashore

  • The project is being lead by the Federal Highway Administration Central Federal Lands Highway Division (CFLHD), in cooperation with Marin County and the National Park Service (NPS).
  • The Subsequent Environmental Assessment with a finding of no significant impact and the Supplemental Initial Study with mitigated negative declaration are available here. The SEA/SIS meets CFLHD's obligations for this project under the National Environmental Policy Act (NEPA) and Marin County's obligations under the California Environmental Quality Act (CEQA).
  • Project Timeline:
  • Environmental Subsequent Study – Summer 2018
  • Finalize Mitigation Plans & Permits – Summer 2018
  • PG&E Pole Relocation Construction – Fall 2018
  • Advertise Project – Winter 2018/19
  • Begin Construction – Spring 2019
  • Complete Construction – Spring/Summer 2021
  • Project Background:
  • Marin County was awarded $17.7 million in federal funds through the Federal Lands Access Program (FLAP) for improvements to approximately 12 miles of Sir Francis Drake Boulevard in Point Reyes National Seashore (the Seashore) in Marin County. As part of the FLAP requirements, the County of Marin is also contributing approximately $2 million in additional local funds. The FLAP is administered by the Federal Highway Administration (FHWA).
  • The purpose of the proposed improvements is to restore the structural integrity of the road and enhance safety for all users while reducing ongoing maintenance requirements. Pavement along Sir Francis Drake Boulevard in the Seashore is deteriorating and badly oxidized, heavily patched, lacks shoulder support, and some sections have significant cracking and edge damage. Seasonal flooding of the creek near Schooner Bay can close the road to traffic for several days. Raising and realigning this short segment of the road has been proposed to help prevent annual flooding and minimize wetland impacts in the area where the adjacent tributary channel has aggraded and is now nearly at the same elevation as the road. The proposed improvements would address these issues through new asphalt pavement, new striping and signs, replacement of two cattle under-crossings, replacement of cross culverts, and implementation of other safety features to meet current design standards.
  • FHWA, in cooperation with Marin County and the National Park Service (NPS), conducted an environmental review process in conformance with both the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA). As a result of the NEPA and CEQA process, a joint EA/IS was prepared that analyzed these improvements to the road and was distributed for public review in July 2015. A Finding of No Significant Impact/Mitigated Negative Declaration (FONSI/MND) was issued in August 2015, Download EA/IS.
  • Since issuance of the 2015 FONSI/MND, improvements have been proposed and evaluated under this SEA/SIS include replacing the existing culverts under SFDB and Schooner Creek with a single-span bridge, and restoring and stabilizing approximately 710 feet of SFDB that has severely eroded. To compensate for permanent wetland impacts as a result of roadway improvements, part of the parking lot at the Drakes Beach would be restored to a wetland, and two ponds would be constructed within Home Ranch to provide California red-legged frog aquatic breeding habitat. Actions at Drakes Beach and Home Ranch extend beyond the original study area analyzed in 2015. The joint SEA/SIS has been developed to meet FHWA’s obligations as the lead agency under NEPA and Marin County’s obligations as the lead agency under CEQA.
