Sidewalks and waterlines are scheduled topics for discussion at a pair of meetings for the Laurie Board of Aldermen. The board will meet twice on Tuesday. At 5:30 they’ll hold a public hearing to discuss their updated sidewalk master plan. That will be followed by the board’s regular meeting, during which they’ll discuss the waterline expansion project, updates on the post office situation, and various commission appointments, among other topics. The regular session begins at 6pm.
