Temporary re-use of closed public school facilities retained in school district ownership, and the reconversion of a temporary re-use back to a school use,
2. 
Permanent re-use of surplus nonresidential facilities (e.g., schools, fire stations, government facilities) not retained in school district ownership, or

Permanent re-use of historic structures listed on the National Register or designated as county landmarks.
