The purpose of this classification and its application is to provide for the location of and grouping of industrial enterprises which involve:
A. 
Bulk handling of products manufactured, treated, processed or assembled on premises;
B. 
Dominant amounts of storage and warehousing;
C. 
Use of heavy duty equipment;
D. 
Heavy movement of traffic on-site, and the generating of large amounts of automobile and truck traffic on adjacent streets;
E. 
Noise and vibration;
F. 
Sites larger than can be provided by normal-sized lots; and
G. 
Similar characteristics and performance standards not detrimental in effect upon other uses of similar nature in close proximity. The grouping of such types of uses permits a pattern of land use, public facilities, utilities and thoroughfares so designed with reference to spacing and improvement as to cater advantageously to the specialized needs of such types of industrial uses. It also makes possible, by grouping enterprises which generate air and water pollutants, to develop and operate facilities for capturing, processing or neutralizing such pollutants through the joint use of such facilities. A further purpose of this classification is to apply zoning protection to industries properly located by prohibiting the intrusion of residential and institutional uses and all commercial enterprises except those which serve as accessory to the needs and convenience of the permitted types of industrial enterprises.
