A land swap that clears the way for cleanup of an Eastside Jacksonville Superfund site has also expanded state parkland on Fort George Island, a nonprofit that was part of the deal said Monday.

The North Florida Land Trust set up the exchange between Florida’s Department of Environmental Protection and the Greenfield Environmental Multistate Trust, an organization responsible for cleaning up the former Kerr-McGee Chemical Corp. property at 1611 Talleyrand Ave.

Environmental Protection Agency project manager Erik Spalvins and Richard Elliott, project manager for the Multistate Environmental Response Trust, two of three groups heading up the Navassa Superfund site cleanup process with the North Carolina Department of Environmental Quality, explain the site isn’t ready for cleanup yet, but it is far enough along to market to developers with an interest in the town.

Partnerships between local, state and federal governments was the theme at a celebration of clean-up at Superfund sites at the former Kerr-McGee site on 14th Avenue North on Thursday.
