Lucas Valley Road Curve Realignment

  • The project is currently underway to realign the sharp 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 $1.6 million project began the first week of July 2021 and is expected to be completed by 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 sharp 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.
  • For more information, please visit the project webpage.

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.
  • 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.
  • General concrete work is also being including on sidewalks, curbs and gutters, ramps, and storm drainage on select roads.
  • Utility work is being conducted by PG&E in conjunction with the roadway resurfacing project.
  • The construction project is expected to be completed by the end of September. The work is being conducted during daytime hours with traffic control measures. Advance notice of traffic impacts will be given to residents to help minimize any inconveniences.

2021 Road Sealant Project: Phase 2 - Rubberized Pavement Project

  • The improvements for Phase 2 of the 2021 Road Sealant Project will include applying pavement preservation treatments to 22.9 miles of roadway in Novato and West Marin that show signs of weathering and pavement cracking. Project areas include Black Point - Green Point, West Novato; Lucas Valley, Point Reyes, Nicasio and the Fallon / Tomales area. One, or a combination of, the following pavement preservation treatments will be utilized on each street: Type II Microsurface, Type III Microsurface, Rubber Cape Sealant, Rubber Chip Sealant, edge grinding and crack-sealing.
  • Traffic impacts are likely to include single lane closures with flagger personal controlling alternating traffic with an expected traffic delay not to exceed ten minutes. Short duration daytime residential road closures with seven days advance notifications are also likely.
  • The Engineer’s estimate for this project is $1.95 million, but the project contract has not yet gone to bid. Work is expected to begin in late August and take a couple of months to complete.
  • The 2021 Road Sealant Project: Phase 2 is partially funded by a California Department of Resources Recycling and Recovery (CalRecycle) Rubberized Pavement Grant. CalRecycle provides grant money to promote markets for recycled-content surfacing products derived from waste tires generated in California and decrease the adverse environmental impacts created by unlawful disposal and stockpiling of waste tires. The rubberized pavement is a proven road paving material that has been used in California since the 1970s. It is made by blending ground tire rubber with asphalt binder which is then mixed with conventional aggregate materials.

Redwood Frontage Road Resurfacing

  • Improvements for this project will include repairing road base failures, and asphalt resurfacing. The work will take place on a small segment of Redwood Highway Frontage Road (approximately 0.15 miles): from the north side of Seminary Drive to the north side of the southern driveway at 580 Redwood Highway Frontage Road.
  • Ten-minute traffic delays during lane closures are expected. Every effort will be made to provide advanced notice and minimize inconvenience to residents and businesses.
  • The Engineer’s estimate for this project is $350,000, but the project contract has not yet gone to bid. Work is expected to begin as early as late August and take about a month to complete.
  • Repairs to this segment of road were originally part of a larger project planned to happen after an electrical undergrounding project between Seminary Drive and Belvedere Drive; however this segment of road is deteriorating too rapidly to delay repairs further, and so it is being handled separately. The electrical undergrounding project is grant funded (Pacific Gas and Electric Rule 20A Grant) and is in the design phase, tentatively expected to go to construction in 2024.

Northern Loma Verde Paving Project

  • Improvements for this project will include repaving several residential roads in the Loma Verde neighborhood (Calle Empinado, Corte Colina, Calle Arboleda and Via Herbosa).
  • Construction will take place during the daytime hours with traffic control measures. It is anticipated that there may be ten-minute delays during lane closures, and two short duration (typically 8 hours) residential road closures per street; however, access will always be provided for emergency vehicles. Every effort will be made to provide advanced notice and minimize inconvenience to residents.
  • The Engineer’s estimate for this project is $650,000, but the project contract has not yet gone to bid. Work is expected to begin as early as late August and be completed by the end of fall.

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.

Proposed Fawn Drive Parking Restrictions

  • Parking restrictions have been proposed along Fawn Drive due to concerns regarding emergency response vehicle access. The proposed restrictions address parking near the Mission Pass Trail entrance (gate area) where through access has a history of becoming impacted.
  • Following review of the location and the identified concerns, the County of Marin has developed a parking restriction proposal with input from the Fire Department, Sheriff’s Office, County Parks, and Traffic Operations.
  • Parking Restriction Proposal:
    • A parking restriction is proposed directly across from the Mission Pass Trail entrance to improve emergency vehicle access.
    • A parking restriction is proposed along the blind curve located in the downhill direction approaching the Mission Pass Trail entrance. The area in the vicinity of the trail entrance gets congested with vehicles, as well as pedestrians and bicyclists entering and exiting the trail. The proposed parking restriction improves sightlines for all users approaching this area.
    • View map of proposed restrictions
  • Since the parking change may impact Fawn Drive residents and Mission Pass Trail users, the County of Marin would like to give you the opportunity to provide comments by September 28, 2021. Please email your comments to DPW_TrafficOps@marincounty.org.
  • These parking restrictions are supported by the Marin County Public Works and will require the Marin County Board of Supervisors' approval to implement. The Board will review public comments and staff recommendations on these proposed parking restrictions at a public meeting this fall. Specific meeting details will be publicized when the date is determined.

Dillon Beach Retaining Wall

  • A 114-foot long retaining wall is being 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. The project cost is approximately $570,000.
  • 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 be completed before winter 2021 storm season.
  • There is an ongoing lane closure in place to allow for the work. Traffic control measures are in place and traffic is using alternating single lane access. Traffic delays are expected through out the project. 

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 Spring 2022 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.

Marin Center Exhibit Hall Seismic Retrofit

  • This project will seismically retrofit the Marin Center Exhibit Hall to mitigate risks to the occupants of the facility in the event of a major seismic incident at the site.
  • Design services were handled by Rutherford & Chekene Engineers and the construction documents were completed in December 2019.
  • The County was informed by CalOES in Spring 2019 that the project had been recommended for a $1.5M FEMA Hazard Mitigation Grant. The project is currently undergoing FEMA environmental review, with the final grant award pending completion of that review.
  • Depending on the grant award timing and the subsequent construction contract bidding process, the construction project is anticipated to begin sometime between late 2021 and early 2022.

Marin Veterans' Memorial Auditorium Seismic Retrofit

  • This project will seismically retrofit the Marin Center VMA to mitigate risks to the occupants of facility in the event of a major seismic incident at the site.
  • The Marin County Board of Supervisors accepted a FEMA Hazard Mitigation Grant for project design in September 2020.
  • Design services are being handled by WJE (Wiss, Janney, Elstner Associates, Inc) and are expected to be completed in Fall 2021.

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.
  • Project Timeline:
  • Public Meeting #1 – November 2016
  • Public Meeting #2 – April 2017
  • Draft Environmental Assessment / Initial Study (EA/IS) available for 30-day public review & comments – Fall 2020
  • EA/IS Public Meeting – November 2020
  • Environmental Permit Completion – June 2021 (expected)
  • Construction Start –TBD 2025

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 – 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.
