Wetland and Creek Restoration at Big Lagoon, Muir Beach
Note: This was formally known as Big Lagoon Wetland and Creek Restoration project.
The Wetland and Creek Restoration at Big Lagoon is a joint project of the National Park Service and the County of Marin, CA. The purpose of the project is to restore a functional, self-sustaining ecosystem, including wetland, riparian and aquatic components and to conduct the restoration in a manner that will re-create habitat for sustainable populations of special status species, reduce flooding on Pacific Way, and provide a compatible visitor experience. The project area is located at Muir Beach, the mouth of the Redwood Creek Watershed which is recognized for its local and regional importance. The project area includes 38 coastal acres encompassing the entire wetland, creek, and riparian area extending from just downstream of Highway 1 to the beach, including a small intermittent tidal lagoon at the beach. The project area is entirely within the boundary of the Golden Gate National Recreation Area of the National Park Service (NPS), but only half of the project site is owned by NPS. Other landowners are the San Francisco Zen Center, which operates Green Gulch Farm, and the County of Marin (County). This project aims to address the extensive loss of natural function for channel conveyance, sediment transport, channel stability, and diminished habitat for federally and state-listed endangered coho salmon and federally threatened steelhead; the increased flooding on Pacific Way; and the critical need for sustainable habitat for the CRLF. The project involves three components: (1) ecological restoration, (2) public access upgrades, including a reconfiguration of the existing parking lot, and (3) replacement of the Pacific Way Bridge. All components are designed to improve ecological function, while accommodating visitors and residents The County and NPS each play a unique role in the project. The County's role is limited to actions related to improvements to Pacific Way and the Pacific Way Bridge, with a joint role with NPS for interim flood reduction actions. All other actions are the responsibility of NPS. All components of the project are related and necessary to achieve the overall goals and objectives of the project; for this reason, they have been included as the whole of the project.
The FEIS/EIR was available for public review in February 2008. The Record of Decision was approved by the Pacific West Regional Director on November 26, 2008 and is available on this site under documents tab.
