TWM performed recovery and restoration surveys in order to recover or reestablish Corps boundary angle points (A.P.) and bearing objects. Using original field notes and plats, TWM was contracted with 19 angle points to recover, restore, or rehabilitate along the exterior boundary of Lake Shelbyville. At each corner there is a possibility of one angle point and two to three bearing objects to be recovered, restored, or rehabilitated. Exhibits were prepared showing dimensions and ties to the recovered and restored monuments.
