The California Coastal Commission has ordered about 200 trailer homes, including many from Sacramento, to leave a Marin County oceanfront campground by 2017.

The decision in a 10-1 vote on Wednesday delivers a victory to the Environmental Action Committee of West Marin and forces the trailer home owners to replace what have been either homes or vacation spots.

The order to vacate replaced a staff recommendation that would have forced trailer owners to rent their homes to others much of the year.

Since the 1920s, people from inland Valley cities, including Sacramento, have found the Marin coast to be a perfect weekend or summer getaway. In the 1960s, the Lawson family, without securing permits, established a formal camping resort amid wetlands, dunes and cow pastures.

After negotiating a package amenable to the family, planning officials and environmentalists, commissioners voted Wednesday to finally give the development a permit. Nearly half of the 960-acre site will be set aside for conservation, campground space will be scaled back, a wastewater system will be built and only about 30 trailers owned by the Lawsons will be allowed to stay.

Lawson's Landing will earn $5 million from the land sale but will lose nearly $1 million in annual revenue from leasing parking spots to 200 trailer home owners.

Commission staff had recommended the trailer homes could stay if the owners rented them to the public for three-quarters of the year. Most trailer owners opposed the idea and questioned its legality. Several commissioners sympathized with them, amending the plan to let them keep their spots for five full years, if they want to. After then, the Lawsons must convert the area to RV spots. Some trailer owners are considering fighting the decision in court.

"It's an unfortunate chain of events," said David Deblasio, a trailer home owner from Woodland. "They say they want to improve public access but by no means will placing handcuffs on a business do that. That to me is pretty sad."

Resort owner Willie Vogler said he appreciated that the commission gave him five years to rethink the Landing's business plan.

"They've limited our options, but there's a lot of things we could do still," he said. "We're not completely dissatisfied."
