In the case any public building, facility or land area, such as a school, recreation area, community center or municipal building, shall cease to be used according to its intended function, the Borough Planning Commission shall study the existing zoning classification of the property on which the said use is located and shall make recommendations to the Borough Council on any necessary zoning changes to ensure a suitable reuse of the parcel.
