Cowell Ranch To Become New State Park

 

Trust for Public Land Bulletin, Winter 2002

    Once known for prodigious agricultural output, California's Contra Costa County is today synonymous with housing construction and traffic snarl. Brentwood, in particular, claims the title of the state's fastest growing city. But through the efforts of the Trust for Public Land, in association with local groups, a good-sized portion of this landscape will remain untouched.
    After several years of community discussion and debate, TPL recently completed a $13-million deal to purchase and preserve nearly 4,000 acres previously earmarked for urban development. The historic Cowell Ranch will remain open habitat, and will enjoy a bright future as our newest state park.
    "The new state park will be one of the defining features of eastern Contra Costa County," says Tim Wirth, TPL-California's San Francisco Bay Area Program Director.
    The roots of Cowell Ranch trace back to 1837, when Dr. John Marsh purchased the 13,285-acre Rancho Los Megaņos from a Mexican landowner, and in the process became Contra Costa's first anglo-American settler. Marsh planted orchards and vineyards and built a massive stone house, which he christened "Brentwood." Wild horses, elk, and antelope roamed the oak-studded hills and grasslands. After Marsh's untimely death in 1856, the ranch passed through a handful of owners until 1924, when Samuel Henry (S.H.) Cowell and his family purchased 4,000 acres. The property retains the Cowell name, and until TPL's purchase, was operated by the S.H. Cowell Foundation.
    What neither Marsh nor Cowell could anticipate is that by the 1980s, this six-square-mile ranch would become the subject of a heated debate between developers and environmentalists. With California's fastest growing suburb just a stone's throw away, Cowell Ranch sat like the last piece of cake at a birthday party. Would Contra Costa County's largest undeveloped property be carved up into a golf course and 5,000 single-family residences, or would its current residents-special-status species like the red-legged frog and endangered San Joaquin kit fox-be allowed to thrive in their natural habitat?
    The S.H. Cowell Foundation first considered development of the ranch back in 1987, a proposal that included homes, schools, and a business park. Contra Costa officials enthusiastically welcomed these new plans as a handy solution for a growing city. In 1990, voters responded by approving Measure C, which drew a new county urban limit line through the middle of Cowell Ranch, bisecting Marsh Creek Reservoir. Hundreds of acres were now up for grabs. Only one portion of the ranch was to be untouched: A 14-acre parcel already owned by the California Department of Parks and Recreation that contains the historic three-story home built by John Marsh.
    But developers and the Cowell Foundation met with a robust public-awareness campaign raised by environmental groups, in particular the Greenbelt Alliance, Sierra Club, and Save Mount Diablo. The groups stressed that while expanded housing might look ideal in the short term, Cowell Ranch clearly represented a rare opportunity for long-term preservation. If protected, the ranch would help create a wildlife corridor that would encompass about 81,000 acres from the Los Vaqueros Reservoir Watershed, extending west through Morgan Territory and Mt. Diablo State Park, to Walnut Creek's Shell Ridge.
    "Cowell Ranch was very highly sought after," says Seth Adams from Save Mount Diablo. "We got decision makers out on the property to show them what was at stake and how different aspects of the urban limit line would affect different areas. We showed them where the line actually was, and what areas should be preserved."
    County officials began to ponder the options. Stellar political support came in the form of state Assemblymember Joe Canciamilla (then county supervisor), and Senator Tom Torlakson (then state assemblymember). "It was a very difficult process," recalls Canciamilla. "It's one thing to move a line, but the board could move it back again. As we negotiated, the goal was not only to move the urban limit line, but to come up with an agreement with the Cowell Foundation, the development communities, the open space advocates and others, that would give TPL the opportunity to come up with the money to acquire the parcel and permanently protect it."
    Through the efforts of Canciamilla and Torkalson, voters agreed to relocate the urban limit line to exclude nearly all of Cowell Ranch. The Cowell Foundation withdrew its development plans and TPL optioned the property. Working on a two-year deadline, TPL's Tim Wirth was able to secure financial commitments from the California Coastal Conservancy, Caltrans, the Department of Parks and Recreation, the Wildlife Conservation Board, and the U.S. Bureau of Reclamation. Later this year, TPL will turn Cowell Ranch over to the Department of Parks and Recreation to create a new state park for the Brentwood community and the whole Bay Area. "Cowell Ranch is a work in progress," says TPL's Wirth. "Our acquisition of the property is a major first step, but there is still a lot of work to be done. In the coming months, State Parks will develop a master plan for Cowell Ranch to determine how best to balance natural resource protection, while also providing new recreational opportunities for this fast growing part of the state."
    "I don't have anything but accolades for TPL and what they've accomplished here," says Save Mount Diablo's Seth Adams. "I look forward to the day when pronghorn and tule elk are wandering over the Cowell Ranch, as they did 150 years ago."
    With your help, over the last 30 years, the Trust for Public Land has created and protected more than 122 special places throughout nine Bay Area counties, totaling more than 20,000 acres-the equivalent of 20 Golden Gate Parks.
