North End Project

Restoring habitat, improving road safety, and adapting to sea level rise in Bolinas Lagoon.

NOVEMBER 5, 2019

Board of Supervisors

The Board of Supervisors approved moving forward with the preparation of construction documents for the Bolinas Wye Wetlands project. The scope of work includes hydrologic and hydraulic analyses, development of design alternatives, design development and construction documentation for stream restoration and realignment, road realignment and road design, bridge design, right-of-way engineering and traffic management, public presentation, project management, and coordination.

The Conceptual Design Report for the Bolinas Wye Wetlands area was presented to the Board of Supervisors on February 27, 2018. The Board directed staff to proceed with recommended design and the environmental review of Phase 1.

SEPTEMBER 29, 2017

BLAC Special Meeting

The draft Conceptual Design Report for the Bolinas Wye Wetlands area on the North End Project was discussed at the Bolinas Lagoon Advisory Council (BLAC) Special Meeting on September 29, 2017. The meeting was held at Audubon Canyon Ranch, Volunteer Canyon, 4800 Highway 1, Stinson Beach, and was open to the public. At this meeting the BLAC provided a recommendation to the Marin County Board of Supervisors.

Bolinas Lagoon Conference

At the State of the Bolinas Lagoon Conference on March 30, 2017, three conceptual design alternatives for the North End project were proposed and members of the public offered feedback. Additional opportunities to comment on this project were offered at the Bolinas Lagoon Advisory Council and the Marin County Board of Supervisors public meetings.


The North End Project is the result of over 20 years of active collaboration between the communities of Bolinas and Stinson Beach and the Marin County Open Space District (MCOSD), Point Reyes National Seashore, Golden Gate National Recreation Area, and the Greater Farallones National Marine Sanctuary.

The Bolinas Wye Wetlands Project is part of a larger vision for the north end of Bolinas Lagoon. Goals include improving habitat connectivity, increasing the resiliency of lagoon wetlands, improving habitat for special-status species, and adapting the existing road network to accommodate projected sea level rise. The Wye Wetlands project includes components that are essential to restoring the north end of the lagoon. Roads must be reconfigured to allow for the dynamic movement of stream channels and for habitats to migrate upland as sea levels rise. These actions will also help alleviate chronic flooding of roadways, improve traffic safety, and prepare other surrounding infrastructure for sea level rise.

The Marin County Open Space District (MCOSD) has received funding for Phase I and II of the North End project. Phase I includes conducting reconnaissance level surveys of the existing biological, cultural, and physical resources within the project area, and identifying the restoration goals for the area bundled into the Site Conditions Report. Phase II includes developing an opportunities and constraints report and three conceptual design plans that address both resource enhancement and transportation issues.
