(1)    Long-range plans. Each state agency which owns listed property shall develop a long-range plan for the management, preservation and improvement of that property. The state agency shall develop the long-range plan as part of the long-range public building program under s. 13.48. The long-range plan shall, to the greatest possible extent, result in preservation of that property.

   (2)   Use of listed property. Before purchasing or constructing a building which is not a listed property, each state agency shall consider using a building which is listed property. A state agency shall use such a building to the maximum extent feasible if the building is appropriate for or can be adapted to meet the needs of the state agency, can be acquired and occupied at a cost which is within the budget of the state agency, is at an appropriate location and meets other requirements of the state agency.

   (3)   Protection of listed property. If a state agency transfers or sells any listed property, it shall reserve a conservation easement under s. 700.40, to be transferred to and held by the state historical society, which secures the right of the historical society to preserve and maintain that property. The state historical society shall establish a form for that conservation easement and provide copies of that form to every state agency.
