Settlement agreements have been signed over a controversial 20 megawatt solar farm for Candlewood Mountain.   Cramer & Anderson, the law firm representing the Town of New Milford and advocacy group Rescue Candlewood Mountain, says Candlewood Solar has agreed to not build a larger than 4 megawatt plant and conserve nearly 90 acres of land as open space.  The appeals of a Connecticut Siting Council ruling will be dropped in exchange.  Opponents of the project have long argued that the project would have destroyed core forest land, a habitat for a threatened species called the northern slimy salamander.  DEEP rejected plans submitted by Candlewood Solar, kicking off the settlement negotiations. As part of the agreement, Candlewood Solar will also create a public walking trail connecting to the Blue-Blazed Hiking Trail.
