While a federal permit needed to proceed with the Glades Reservoir project remains in limbo, local governments and authorities are extending the time frame for negotiations with Glade Farm LLC about payments and other proposed amendments to a lease management agreement. The Gainesville and Hall County Development Authority on Monday approved extending the terms outlined in a 2010 “letter of intent” until July 31, 2015. Meanwhile, the Hall County Board of Commissioners will vote on whether to extend the agreement when it meets Thursday.
