This handbook is a guide for public works management, planning, and maintenance personnel involved with inactivating, closing, reactivating, or providing caretaker maintenance to individual facilities, groups of facilities, or whole bases. The handbook provides general guidelines and points for consideration, but it is not intended as a detailed plan for every individual activity. Using information from this handbook and other sources, shore activities should develop a plan of action and milestones (POA&M) tailored to the specific activity. When inactivating, closing, or reactivating involves many facilities and effects large numbers of personnel, a more formal planning process is required. It is usually appropriate to prepare a formal Master Plan (OPNAVINST 11000.16, Command responsibility for Shore Activity Land and Facilities), or revise the existing Master Plan to help document facility needs.
