Marin County’s water resources include a network of fresh and marine water systems that support globally significant and extraordinarily diverse onshore and offshore habitats. In rural West Marin, there are miles of county, state and federal trails and coastal public access points spanning from Dillon to Muir beaches where one can explore Bolinas Lagoon, Tomales Bay or the vast Pacific Ocean. Off Marin’s shores, one can experience the abundant biodiversity of the Greater Farallones and Cordell Bank National Marine Sanctuaries and the network of California’s Marine Protected Areas. 

Since 1971, EAC has protected and sustained West Marin’s vibrant watersheds, including Tomales Bay and Bolinas Lagoon. We accomplish our work by protecting, preserving, and enhancing the unique and vulnerable marine and freshwater resources and habitats of these water bodies; restoring and maintaining water quality; and supporting policies and actions which employ precautionary principles to sustain the complex ecological functions of the watersheds.

Our prior successes include protection of the Estero Americano and Estero San Antonio from land use development and sewage waste, banning the use of jet skis in the Greater Farallones National Marine Sanctuary, protecting eelgrass habitat, securing a Marin County ordinance against offshore oil infrastructure, and the designation of Tomales Bay as the 19th USA Ramsar site, or wetland of international importance (nomination and update). Our current waters campaigns center around Ensuring Resilient Watersheds and Safeguarding our Coast and Ocean.

For nearly fifty years, EAC has been actively bringing people, science, and policy together to champion innovative solutions for local environmental problems. Currently, we are actively engaged in coastal protection policy work and coastal resiliency planning efforts through submitting comments, testifying, community engagement, and participating in stakeholder groups. With climate change, pollution, shifting political priorities, tourism, and other factors impacting our environment, EAC remains fastidious in reviewing and researching issues important to our coastal communities.

OPPOSING OFF-SHORE OIL

Sunrise Movement Protest,  Photo © EACIn 2016, the Trump Administration launched a campaign to allow offshore oil leases throughout the United States, including the Pacific Coast and Northern California. We are working to protect coastal resources from the threat of offshore oil and gas extraction on the Pacific Coast. In 2020, thanks to our advocacy, Marin County passed an ordinance banning offshore infrastructure without voter approval, placing a kink in the Trump plans. PROGRAM AREAS: •  Protect the Pacific/Offshore Oil

Advisory Committee

Our Advisory Committee (board, staff, and other stakeholders) provides expertise and advice on the complicated issues facing our lands, waters, and biodiversity in coastal Marin. Their feedback and recommendations help broaden our view and scope when making decisions involving marine, coastal, freshwater systems, including Tomales Bay and Bolinas Lagoon, our local wetlands of international significance, and climate change issues impacting water resources. View our guiding principles for our work on issues facing Tomales Bay, Bolinas Lagoon, and their watersheds.
