A key traffic artery between two major South Hall roads and cutting through a major subdivision will be partially closed 90 days, starting within a couple of weeks, for improvements. Newland Communities, developer of the sprawling Sterling on the Lake subdivision, is “performing infrastructure improvements as required by the state and federal permitting to Capitola Farm Road,” according to a notice sent Friday to Sterling residents. Capitola Farm, which runs between Spout Springs and Hog Mountain roads, will be closed between Lake Sterling Boulevard and Lemon Grass Lane.
