The Navy is seeking the public’s opinion on a proposed $20 million cleanup of 47 acres of Alameda Point that city leaders hope will someday serve as a town center with a mix of homes, businesses and parks.

Comments will be accepted through May 31, and a public hearing on the plan is scheduled for May 15.

The site is now home to a former fuel storage area, a pair of aircraft engine test facilities and a ship fitting and engine repair shop. Their past uses left cobalt, chromium and a host of other toxics in the dirt and a pair of chemicals that have been shown to cause cancer – trichloroethylene, a solvent, and vinyl chloride, a main ingredient in plastic PVC – in groundwater.
