It is the intent of this Section that provisions be made to insure a reasonable choice of appropriate uses in the case of a change in use of the non-use, abandonment or sale of property presently zoned for institutional use. In such an event the Planning Commission will review the specific site and make a recommendation to the Council of the Village of Highland Hills concerning the most appropriate use for the site, and shall recommend a zoning district classification for the Zoning Map to accomodate such uses.
