About Us

The Environmental Action Committee of West Marin was founded in 1971 by a group of citizens who wanted both to protect the region from immediate threats and to foster a wider understanding of its unique qualities.


The Environmental Action Committee of West Marin is a tenacious, highly effective grassroots advocacy organization founded in 1971 that is dedicated to the protection and appreciation of West Marin’s wild lands, wildlife, wilderness, watersheds, and rural character.

EAC works for clean air, pure waters, healthy ecosystems, a diverse and thriving native flora and fauna, and the preservation of a rural, community spirit. EAC uses law, policy, science, and education to:

  • monitor, publicize, and campaign against threats to West Marin’s natural environment,
  • educate the public and policy-makers about the environmental issues facing West Marin,
  • provide reliable information about controversial issues in order to create a common ground of understanding and promote informed debate, and
  • encourage and facilitate productive resolutions to land-use conflicts by working closely with those who own, manage, and use West Marin’s lands.

West Marin consists of 13 unincorporated communities.

In the absence of local government, EAC provides an essential voice on behalf of the area’s priceless natural resources before the many boards, commissions, and agencies of County, State, and Federal government. As the only regionwide environmental watchdog and the only environmental advocacy group in West Marin with an office and staff, EAC has the successful advocacy experience and an intimate day-to-day knowledge of the area that environmental groups based elsewhere do not have.

EAC’s mission is to protect and enhance the natural environment of West Marin. We have been doing that for more than 40 years.

Some of our many past accomplishments:

  • One of EAC’s first battles was over a plan to dike the southern end of Tomales Bay and destroy its tidal wetlands. EAC organized a well-publicized “sail-in” of local craft that drew attention to the scheme and mobilized public opposition to it. The campaign was successful: the filling was stopped. In the same year, EAC was an important voice in the chorus of criticism that ultimately killed the County’s West Marin Plan, which called for a six-lane highway from the Golden Gate Bridge to Point Reyes and 1.3 million new homes in West Marin.
  • In the late 1980s, when a consortium of waste haulers tried to expand the West Marin dump into a regional landfill, EAC helped form Waste Watch, a coalition of community groups that engaged in a nearly decade-long struggle and ultimately succeeded in stopping the expansion.
  • In 1991 EAC sponsored a habitat survey of Stinson Beach’s Easkoot Creek that became a keystone of the Bolinas Lagoon Management Plan.
  • In the early 1990s, when Santa Rose decided to dump its sewage water in West Marin, threatening the fragile ecosystems of Estero Americano and Estero San Antonio, EAC was there. In conjunction with Friends of the Estero, we sued the City of Santa Rose, forcing it to drop the plan.
  • In 1992, when the Park Service announced a plan to kill Tule elk for herd reduction, EAC successfully opposed it. We then worked with the Park Service to develop an innovative plan to use contraceptives to humanely control herd size.
  • EAC has co-produced four State of Tomales Bay Conferences. These have focused scientific attention on the health of the Bay and its watershed, raised public awareness of the issues facing the Bay, and forged important links between scientists, researchers, environmentalists, ranchers, and public agencies.
  • In the mid-1990s, when developers proposed the Marin Coast Golf Ranch, a golf course and luxury home development at the mouth of Estero San Antonio, EAC was there. Our aggressive campaign against it, forced the developers to withdraw their proposal. When a Singapore group then stepped in with a scheme to build million-dollar trophy homes, we kept up the pressure until they too bowed out.
  • In 1995, when the Mt. Vision fire destroyed scores of homes on the Inverness Ridge, EAC published the Phoenix Report, which provided crucial advice to fire victims and others about how to live with and protect the vulnerable Inverness Ridge ecosystem.
  • In 1996, EAC conceived, published the acclaimed West Marin Green Guide on recycling, reuse, reduction.
  • In 1998, EAC produced “Madre Tierra Solo Hay Una,” a ground-breaking environmental educational video aimed at the Hispanic community, the first such bilingual video in the United States.
  • In 1999, EAC stopped CalTrans from cutting down most of the trees on Point Reyes Station’s Main Street, Highway One.
  • In 2000, EAC convinced the County that the Master Plan for Lawson’s Landing requires a full Environmental Impact Report because of the potential impact on Tomales Dunes.

International recognition for Tomales Bay

EAC led the charge to secure international recognition for Tomales Bay. The US Department of the Interior and the International Secretariat of the Convention on Wetlands (commonly known as the Ramsar Convention after the Iranian city in which it was signed) have accepted EAC’s nomination of Tomales Bay as a Wetland of International Importance. There are only 18 other Ramsar sites in the United States, and only one other in California, Bolinas Lagoon. To qualify, Tomales Bay had to meet rigorous standards. Among its notable characteristics: it supports more than 50 species of waterbirds, numbering more than 20,000 individuals; it is visited by more than 1% of the world’s populations of black brant, dunlin, and western sandpiper and is home to 10% of California’s coho salmon; it is a major spawning ground for Pacific herring; and it supports 13 threatened or endangered species.

Former EAC board member and president, Jules Evens provided the scientific data for the nomination, which the Interior Department said was the most compelling Ramsar nomination it has ever received. The nomination was seconded by Ed Ueber, former Manager of the Farallones National Marine Sanctuary, and Don Neubacher, former Superintendent of the Seashore, which are the two entities that “manage” Tomales Bay. We also had the support of Senator Barbara Boxer, Congresswoman Lynn Woolsey, Supervisor Steve Kinsey, and many other individuals and community groups. Edgar Wayburn, who led the effort to have Bolinas Lagoon named a Ramsar site, advised and encouraged us. In naming Tomales Bay a Ramsar site, the United States has made a commitment to the international community to protect its ecological character.

  • In 2001, after five years of campaigning, EAC convinced the federal government to issue regulations banning jet skis from the Gulf of the Farallones Marin Sanctuary, including all of Tomales Bay. At 948 square nautical miles, this is now the largest jet ski-free area in the country-and one of the largest in the world.
  • In 2001, EAC formed the “Steelhead Coalition” with other environmental groups and convinced the Board of Supervisors to reverse a Planning Commission decision allowing the Shakespeare at Stinson theater company to put several buildings in the Stream Conservation Area of Stinson Beach’s Easkoot Creek, a steelhead stream.

Jet skis banned from Tomales Bay and the Marin coast

In 2001, after five years of campaigning, EAC convinced the federal government to issue regulations banning jetskis from the Gulf of the Farallones Marin Sanctuary, including all of Tomales Bay. At 948 square nautical miles. this is the largest jetski-free area in the country-and one of the largest in the world. When the ban was announced, Ed Ueber, Manager of the Gulf of the Farallones National Marine Sancutary, sent us this message.

The work, patience and perseverance done and shown by EAC has lead to a precedent-setting and forward-looking way to protect the valuable, beautiful and mysterious resources of the Gulf of the Farallones. You should all be very proud. The world, nation and I thank you.

Banning Genetically Modified Organisms from Marin Agriculture

In November 2004, Marin voters approved a ballot initiative to ban Genetically Modified Organisms (GMOs) from Marin agriculture.

Protecting Agricultural Lands and Salmon Creeks

EAC has succeeded in stopping or altering many residential developments planned for agricultural lands, in Bolinas, Nicasio, on the East side of Tomales Bay. EAC has succeeded in stopping or altering many developments proposed for Stream Conservation Areas throughout West Marin. This protection work is ongoing.

Tomales Dunes Protection at Lawson’s Landing

After forty years of advocacy, in July 2011 EAC was successful in protecting a rare treasure in Marin County, the Tomales Dunes-wetlands complex, when the California Coastal Commission heeded EAC’s call to strike a balance between protecting environmentally sensitive habitat and supporting the continued operation of this large, family-owned coastal campground. For more information on EAC’s tremendous effort over the years to protect this rare habitat, visit the Tomales Dunes page.

Industrial Wind Towers on East Shore of Tomales Bay

In the fall of 2010, Marin County was prepared to allow guy-wired study towers for industrial wind turbines to be sited on the ridgelines of the East Shore of Tomales Bay without any environmental review. EAC led the charge to successfully challenge the County’s unlawful, arbitrary approval of the towers. EAC is working to ensure that any wind turbines are the appropriate height, style, and are sited appropriately to protect West Marin’s huge avi-fauna diversity.

Local Coastal Program Amendment

Since 2009, EAC has attended every public hearing and workshop held by the Marin County Planning Commission and Board of Supervisors regarding the Local Coastal Program Amendment. EAC continues to work tirelessly to ensure that existing protections for our precious coastal resources, which are state and national treasures, are not weakened by the LCP Amendment. Visit the Coastal Protection  for more information about EAC’s tireless efforts to protect West Marin’s Coastal Resources.
