Gainesville is looking to plant 180 trees at three U.S. Army Corps of Engineers parks as part of an “environmental stewardship” effort tied to the Clarks Bridge replacement project. The city is involved in moving utilities as part of the Georgia Department of Transportation’s bridge project on Ga. 284/Clarks Bridge Road at Lake Lanier, an effort that requires a permit from the corps to use its property. “One of the requirements in the easement process is they determine environmental impacts,” said Matt Tarver of Gainesville’s Public Utilities Department.
