1. INTRODUCTION
Marin County Parks and Open Space District (MCP), is soliciting proposals from qualified firms to
provide design services and prepare construction documents for the Bolinas Lagoon Wye Wetlands
Project (Project). The design process will be completed in coordination with the Golden Gate National
Parks Conservancy (Parks Conservancy) as a One Tam project. The Bolinas Lagoon Wye Wetlands
Project location is at the north end of the Bolinas Lagoon Open Space Preserve (Preserve), located in
Bolinas, Marin County, California (see Location map). The Project is part of the larger Bolinas Lagoon
North End Visioning Project (“North End Project”). The goal of the North End Project is to restore
important wetlands and streams; protect wildlife and their essential habitats; improve safety and
reduce flooding; and, create climate change resiliency. MCP has developed 10% Draft Conceptual
Designs for the Project (illustrated in Figures 1- 4), which will be the basis of the design process. The
current design scope of work includes but is not limited to: design development and construction
documentation for hydrologic and hydraulic analyses, stream restoration and realignment, road
realignment and road design, bridge design, right-of-way engineering, traffic management design,
public presentation, and project management and coordination. One consultant team will be selected
to perform all design and construction document development tasks for the Project.
Through this RFP process, MCP will select a firm based upon the criteria detailed in Section 6 and will
award a Not-to-Exceed professional services contract. This contract will be administered by MCP. MCP
reserves the right to adjust the scope of services as deemed appropriate and necessary. Work may be
authorized in phases as deemed necessary to maintain the project schedule.
2. BUDGET AND FUNDING
This project is funded by a California Coastal Conservancy Proposition 1 Grant and Marin County Parks
Measure A. Two-hundred and eighty-five thousand dollars ($285,000) is available for the design
services described in this Request for Proposals. Additional funding may be made available depending
on compelling arguments and need.
3. ROLES
MCP will provide overall project management and coordination. MCP will work with the Parks
Conservancy and other partnership agencies to facilitate data sharing, site studies, complete design
review, and other actions to complete the design process. In-person meetings and conference calls
will be scheduled for key milestones. MCP will facilitate coordination with Marin County Department
of Public Works and Caltrans for road design development. MCP, the Parks Conservancy, and Marin
County Department of Public Works will be collectively referred to as “Parks”. Parks will be
establishing an independent review body (Technical Advisory Committee, TAC) made up of technical
experts and regulatory staff to participate in design review of the project.

4. PROJECT DESCRIPTION
Bolinas Lagoon is located in Marin County, California, just north of San Francisco (Figure 1). This 1,100-
acre tidal estuary is one of only four Ramsar-designated Wetlands of International Importance on the
West Coast. It is a key component of the Greater Farallones National Marine Sanctuary, and one of the
most ecologically important places within MCP’s system of protected areas. The lagoon is a major
water bird wintering area and stopover point for migrants along the Pacific Flyway. Two hundred and
forty-five bird species have been identified in the lagoon and its watershed, including over 20 special-
status species. It has been designated an Audubon Important Bird Area in recognition of its valuable
open water, mudflat, and marsh habitats. These habitats also support many other species, including a
large harbor seal breeding colony, and numerous amphibians, mammals, and plants including rare,
threatened, and endangered species.
This request for proposals is for the first critical step of the North End Project. The Project is a
partnership of MCP, the Parks Conservancy, National Park Service, Greater Farallones National Marine
Sanctuary, Greater Farallones Association, and partially funded by the California Coastal Conservancy.
In December of 2017, a Conceptual Design Report for the North End Project was completed. Within
the report three alternatives were proposed for reconnecting Lewis Gulch Creek and Wilkins Gulch
Creek. All three alternatives were phased (Phase 1, 2, and 3), with Phase 1 (Bolinas Lagoon Wye
Wetlands Project) being identical for each alternative. On February 27, 2018, the Marin County Board
of Supervisors directed Marin County Parks and Open Space District to proceed Project because of its
independent utility.

5. SITE DESCRIPTION
The project area is centered around the intersection of Olema Bolinas Road, the Crossover Road
(“Bolinas Wye”), and State Route 1 (Figure 1). It is approximately 4.7 acres in size. Culverts and roads
prevent the migration of Lewis Gulch Creek, and block natural processes that provide the water,
sediment, and nutrient exchange needed to support wetland habitat transitions. This low-lying and
flood-prone site is predicted to flood frequently under both near- (2050) and long-term (2100) sea
level rise (SLR) scenarios, with a predicted 35 feet of SLR in this area over the next century. Low-lying
lands (inter-tidal marsh) and roads will be inundated, and the water will need to spread into upland
areas that are currently disconnected from the north end of the lagoon. Restoring natural processes
by removing hydrologic and migration barriers will connect upland and lowland areas, allowing the
site’s habitats to continue to shift, adapt, and be resilient in the face of future climate change and SLR.
Actions at this project site are particularly critical, as it is the only place in the entire lagoon where
contiguous lands that can accommodate wetland habitat migration are being managed by public
agencies, and so are guaranteed to remain permanently protected in perpetuity.
6. PURPOSE AND PROPOSED RESTORATION ACTIONS
The objectives of the Project are to connect Lewis Gulch Creek to its floodplain and allow it to self-
form and migrate; to allow for fish passage; and to improve traffic safety on State Route (SR) 1 at the
intersection of Olema Bolinas Road. A new creek crossing will be installed on Olema Bolinas Road to
better accommodate flows, improve geomorphic processes, and improve hydrologic connectivity
between ground water, surface water, and Bolinas Lagoon. The Olema Bolinas Road plan and profile is
shown on Figure 3. The five main project components are noted below. Please see AECOM design
report for full description, link located in References.
Remove the crossover road, which connects Olema Bolinas Road with SR 1 (Figure 2).
Reconfigure the SR 1/Olema Bolinas Road intersection (Figure 4).
Upgrade the existing Lewis Gulch Creek/SR 1 culvert to a larger culvert or small bridge
(Figure 2).
Install a bridge crossing just south of the reconfigured intersection along Olema Bolinas
Road, raise the adjacent roadway (Figure 2 and 3) to accommodate the new design grade
and redirect Lewis Gulch Creek onto the relict alluvial fan.
Stabilize the Lewis Gulch Creek streambank adjacent to SR 1, north of the Olema Bolinas
Road intersection (Figure 2).
If needed, install a new culvert near the intersection of the existing crossover road and
Olema Bolinas Road (see Figure 2 and 3, Phase 1).
