These stakes show the planned locations of building corners and parking lots for the proposed Campus Hotel. David Laby brought the existence of these up at the Town Hall meeting, and Barbara Chernow denied that they had anything to do with the hotel.
Notably, there are two trees that were recently cut down (picture 11 and 26). The first of these is within a few feet of one of the parking lot stakes.
