SAN FRANCISCO -- Walmart's plan to expand its Antioch store into the East Bay's first supercenter has cleared its final legal hurdle after an almost 10-year battle.
The state Supreme Court decided this week not to hear a petition by a coalition of environmental, civil rights and labor groups over an appellate court decision last November affirming Antioch City Council's September 2010 approval of Walmart's development plan.
The big-box retailer's planned 33,575-square-foot expansion and remodel would include a bakery, produce, full-service deli and enhanced outdoor living department.
The California Healthy Communities Network has argued the council's decision should have required full environmental studies looking at potential urban decay in the area, including economic and environmental effects such as increased traffic and impacts to other grocery stores.
Phil Tucker, project director for the Healthy Communities Network, contends that the Contra Costa Superior Court's decision in October 2011 was right in saying Antioch misinterpreted its laws when requiring environmental studies historically but abruptly not doing so in 2010.
The 1st District Court of Appeal reversed that ruling in November.
City Attorney Lynn Tracy Nerland said in an email that Antioch is "pleased that the Supreme Court found no reason to question (its) planning and environmental procedures for development proposals."
Tucker acknowledged Thursday that the Supreme Court's dismissal ends any further legal challenges.
Walmart is in the process of moving forward with its expansion plans, Rachel Wall, a company spokeswoman said.
"Grocery is an area that customers have come to expect from Walmart, and we look forward to soon starting work on our store expansion," Wall wrote in an email.
Antioch can issue building permits once Walmart submits drawings and documents that comply with its conditions of approval and city building code, according to city planners.
Tucker said that the Healthy Communities Network will still work with local residents opposed to the expansion and "monitor (the project) to make sure they follow the rules."
Walmart submitted plans in 2004 -- four years after its store opened -- to expand its 134,000-square-foot store on Lone Tree Way.
In both 2007 and 2010, Antioch required Walmart to review the environmental effects of building the supercenter, twice rejecting its environmental documents in split decisions.
But, Antioch's council reversed its decision in August 2010 after legal counsel for Walmart and the city argued that it could not consider environmental issues in a design review application, citing a case involving a San Diego redevelopment project.
The original approval for Williamson Ranch Plaza in 1998 allowed for Walmart's expansion.
