Inland in Morgan or Jasper, clearing a pasture edge is mostly a question of price. On a Lake Oconee lot, Georgia Power's shoreline guidelines decide the first 25 feet for you: no grubbing or reshaping the contour in that buffer or on project land without written approval. Clear it anyway and Georgia Power can require a revegetation plan, pull docks at the owner's expense and stop issuing lake-use permits.
Georgia Power does consider tree removal to make room for a house, seawall or septic installation, but it asks for 1:1 replanting with native species. On Lake Sinclair the paperwork for a new dwelling includes a landscaping plan that counts trees 4 inches in diameter or larger coming out within the building perimeter and the driveway.
The septic system shapes the clearing too. On the clay ridges between the coves, the one patch of deep, well-drained soil is often where everybody wants to park the equipment. Keep machines off it.
