In a ruling Monday, the Superior Court of San Francisco rejected plans to transfer contaminated Navy property to the city, SF BayView reports.

The land is slated to be part of a 702-acre development project, approved last year by the San Francisco Board of Supervisors, which will include 10,500 housing units and a new 49ers stadium.

Environmental advocacy groups contend that transferring the land to the city before the clean up is completed could expose residents to toxins and the city to financial liability.

“This ruling to block early transfer is an important win for this community that had been dealt a stacked deck,” Jaron Browne, Bayview Project Organizer of the group POWER, told SF BayView.

The pollution problems at the shipyard are many: remnants of fuels and solvents used to build warships in WWII, radioactive waste from a naval radiological defense laboratory and waste from a criminally incompliant machine shop that once leased the shipyard.

The Hunter’s Point Shipyard is the only Superfund site in San Francisco, a designation bestowed by the Environmental Protection Agency on sites with levels of hazardous contamination that threaten public health.

In Monday’s ruling, the court cited the failure of the city to study early transfer activities in their Environmental Impact Report.

While the ruling is just a tentative statement of decision, George Torgun, Staff Attorney at the firm Earthjustice, who represented community groups in the lawsuit, said that it will likely reflect the court's final ruling, which he expects will be issued next month.

“I think everyone would like to see redevelopment happen and would be happy with the jobs and development that it would create,” Torgun said. “We’re not opposed to development, but there just needs to be assurances that the Bayview Hunters Point community is protected from adverse health effects, especially given that those communities are especially impacted by pollution.”
