Description: 12 concrete protective vault segments were arranged on a 15" bed of soil and a 1" thick plywood sheet. Each vault segment was centered over its corresponding plywood sheet. Vault segments were positioned with .6" gaps. The joint between the middle two segments was centered on the fault. There were sheet metal covers connected to the east and west sides of the south end of each vault segment overlapping several inches of the north end of the next segment (to the south).
