The Local Zoning Board of Adjustment and Appeals (LZBAA) shall, subject to the requirements of this Section, allow other uses not enumerated hereunder provided that they are compatible with the uses expressly allowed. Allowance of further uses shall be based on the intrinsic qualities of the land and the socio-economic potential of the area with due regard to the maintenance of the essential qualities of the zone. Specific uses/activities of lesser density within a particular zone (R-1) may be allowed within the zone of higher density (R-2, R-3) but not vice-versa, nor in another zone and its subdivisions except for uses 120 21 1 Id. at 237.
