M54
General Impact Industrial
The M54 Use Regulations are intended to create and preserve areas where manufacturing and industrial uses not having high nuisance characteristics may locate. Non-industrial uses which support industrial uses are permitted within the zone, particularly administrative, sales, and services uses. Typically, the M54 Use Regulations would be applied near rail and trucking facilities, or other locations where impacts associated with noise, odor and traffic would not impact on residential or commercial areas. All outdoor storage areas would be subject to screening regulations in Section 6706. Various applications of the M54 Use Regulations with appropriate development designators can create a large transportation-dependent industrial center or a small, geographically isolated grouping of a few small scale industrial uses.
Permitted uses
Include but are not limited to:
Automotive
