The Heavy Commercial zone (CM) is established to provide an area in which a congruous mixture of retail commercial, warehousing, heavy commercial, and light manufacturing uses may be established. The zone is to be used primarily as a transitional zone between industrial areas and residential areas and/or lighter commercial districts. The zone is also intended to provide for the location of manufacturing and warehousing operations which are operated in conjunction with and incidental to a retail commercial establishment. The CM zone should be located in those areas where it provides service as a transitional zone and where there is adequate accessibility to good transportation facilities. Care should be taken in the location of this zone that heavy volumes of truck traffic generated by a warehousing and light manufacturing uses do not traverse through a residential neighborhood or a retail commercial area in order to reach major highways or rail facilities. The uses characteristic of this zone will be warehouses, light manufacturing or assembly plants, machine shops, automobile repair facilities, furniture and appliance repair, tire recapping, and building materials stores and yards. The CM zone should be characterized by buildings and grounds which combine utility and attractive appearance. The utility of buildings, parking areas, and loading facilities should be softened with landscaped areas along all street frontages.
