Mill Valley – Sausalito Pathway Project (East Blithedale to Almonte)

The popular Mill Valley-Sausalito Multiuse Pathway was constructed more than 30 years ago and has never had a significant pavement upgrade. With federal grant money in hand, the County of Marin plans to lay a fresh coat of smooth asphalt and make accessibility improvements on almost a mile of the pathway by late 2017.

For more information please visit the project web page.

Muir Woods Road Improvements in Muir Woods National Monument

The County has been approved for over $5.2M in grant funds for the resurfacing and rehabilitation of 2.48 miles of Muir Woods Road through the Muir Woods National Monument to State Route 1 in Muir Beach. This stretch of Muir Woods Road is the only roadway providing access to the Muir Woods National Monument. This project will improve both safety and function for 2.48 miles on this roadway through pavement rehabilitation, road stabilization, drainage improvements, roadway widening, and improved signage and striping. The County’s local match contribution is $676K. This project is being led by the Federal Highway Administration (FHWA) with construction as early as 2019.

Muir Woods Road 

Muir Woods Road Parking Barrier Project

In coordination with the National Parks Service and State Department of Parks and Recreation (CDPR), the County has prepared plans for a parking physical barrier system along Muir Woods Road.  The plans incorporate a combination of a post barrier system, and a post and cable assembly to improve traffic safety and discourage or prevent parking along the narrow Muir Woods Road shoulder. Approximately a little over a mile of post system with reflective markers, both above Muir Woods National Monument entrance, and south towards Kent Canyon has been installed. In addition, where lacking, white edge striping has also been added to the roadway to better define the edge of pavement. Additional No Parking zones signage has been installed along with erosion and sediment control measures. The construction was completed approximately at the end of February.

An activity update and joint presentation by the County and National Park Service was made before the Marin County Board of Supervisors on June14, 2016. View the Presentation

North/South Greenway Gap Closure Project

In coordination with TAM, SMART, Caltrans, the City of Larkspur, and Town of Corte Madera the County plans to implement one of two TAM sponsored projects that will close a key gap in the local and regional non-motorized transportation network between the Central Marin Ferry Connector (CMFC) and the existing multi-use paths at the intersection of Old Redwood Highway and Wornum Drive.

The project is funded using Regional Measure 2 (RM2) funding, which is a result of the voter approved $1.00 toll increase of the seven state-owned toll bridges in the San Francisco Bay Area. The Marin County Department of Public Works is managing this project in coordination with TAM, SMART, the City of Larkspur and Town of Corte Madera.

The project consists of two separate and distinct projects. The "Northern Segment" will join the Central Marin Ferry Connector Path to a new multi-use path over Corte Madera Creek using the east side of the Caltrans Northbound Highway 101 highway structure to connect with Old Redwood Highway. This project will be led and managed by TAM.

The "Southern Segment" project, which is led and managed by the County of Marin, will connect to the "Northern Segment" at Old Redwood Highway and will cross over to the levee path and will continue south down to connect to the existing paths at Wornum Drive.

The County initiated work on the Southern Segment project in 2015. The project includes a topographic survey, collection of information and data, seeking public input on concerns and suggestions for improvements, design of construction plans, right-of-way easement acquisition, associated environmental review and construction.

Sir Francis Drake Boulevard Road Rehabilitation in Lagunitas

Sir Francis Drake Boulevard, a popular gate way from the Highway 101 corridor to rustic West Marin towns such as Olema and the San Geronimo Valley, was constructed more than 50 years ago and there are several remaining segments in need of repair. With Measure A funds in hand, the County of Marin plans to lay a fresh coat of smooth asphalt and make various accessibility improvements.

Sir Francis Drake Boulevard Road Rehabilitation in Lagunitas 

The Marin County Department of Public Works (DPW) will oversee the design and construction of the project on the roughly 1.5 mile long stretch of roadway between Lagunitas Road on the west and Wild Iris Dr. to the east.

This segment of Sir Francis Drake Boulevard is an arterial roadway that acts as the major thoroughfare between Olema, the San Geronimo Valley and urban areas of Marin County. The roadway will be restriped and resurfaced as the existing pavement is in poor condition and has an average Pavement Condition Index (PCI) of 28. The project improvements will comply with current American Disability Act standards and will further analyze opportunities to improve pedestrian safety as there are two existing crosswalks and two transit stops within the project limits. Opportunities to improve bicycle safety and repairing existing culverts will also be considered as part of the design and multi-modal review process.

The County of Marin was awarded $937,000 in Measure A, Strategy 3.1 funds which are allocated for Major Roads and Related Infrastructure.

The anticipated project timeline is as follows:

Fall 2016
Begin Survey and Preliminary Engineering
Winter 2017 Final Design
Spring 2017
Bid Final Plans
Summer 2017
Begin Construction
Fall 2017 Complete Construction

Sir Francis Drake Boulevard Improvements in Point Reyes National Seashore

The Federal Highway Administration Central Federal Lands Highway Division (CFLHD), in cooperation with Marin County and the National Park Service (NPS), announces the availability for public review and comment of the Environmental Assessment/Initial Study (EA/IS) for Sir Francis Drake Boulevard Road Improvements. The EA/IS meets CFLHD's obligations as the lead agency for this project under the National Environmental Policy Act (NEPA) and Marin County's obligations under the California Environmental Quality Act (CEQA).

The Environmental Assessment/Initial Study (EA/IS) with proposed Mitigated Negative Declaration for the Sir Francis Drake Boulevard Improvement Project is available for public review and comment from July 15, 2015 to August 13, 2015.  PUBLIC COMMENT PERIOD IS NOW CLOSED.

The Environmental Assessment with Finding of No Significant Impact and Initial Study with Mitigated Negative Declaration is available here, along with the related Appendices.

Project Background

Marin County was awarded $15 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). FHWA, in cooperation with Marin County and the National Park Service (NPS), is initiating a planning and environmental review process in conformance with both the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA).

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.
