Why is ACR interested in a living shoreline project at Cypress Grove?
The Tomales Bay Living Shoreline Feasibility Project is an exciting opportunity for ACR to collaborate with the State and County, to help create a “proof of concept” that may be beneficial to future projects on Tomales Bay as well as other shorelines around the world.
The proposed project at Cypress Gove primarily addresses the site’s vulnerability to flooding. It seeks to:
• restore natural sediment transport processes,
• restore and preserve the beach habitats that have historically protected the site, and
• improve upland (dune and backshore) habitats through revegetation.
The beach restoration would work in concert with offshore native oyster restoration, which would act to stabilize the new shoreline and integrate with large woody debris features that would retain sediment and enhance shoreline habitats.
The project is expected to provide added protection to the site for up to 1.6 feet (50 cm) of sea-level rise. Beyond this point, ACR would likely need to include additional adaptive measures to be successful, such as relocation or raising of the existing buildings.
What is the cost of the proposed project?
The County currently estimates the costs for the proposed project at Cypress Grove to be $1.26 - $2.7 million. The proposed project comes at no financial cost to ACR.
What’s the timing?
We don’t yet know the timing for the work to begin at Cypress Grove. A feasibility study, linked below, has suggested several next steps.
