The Heavy Manufacturing (M2) zone is established to provide areas in the community where heavy industrial, manufacturing, and extractive uses may be located in an environment which protects them from the encroachment of commercial and residential uses, and which reduces the effect of undesirable characteristics such as odor, dust, and noise upon surrounding residential or commercial areas. The zone is also intended to provide for the development of incidental service facilities such as restaurants, service stations, and public facilities intended primarily to serve the industrial area. The M2 (Heavy Industrial) zone should be located in areas which are readily accessible to railroads and major highway routes. Truck traffic generated by the M2 zone shall not be required to ingress and egress from industrial areas through a residential area or commercial district. Said zone shall also be located in areas which will insure the purity of air and waters within Provo City and will not create hazards to nearby residential, commercial, or light manufacturing areas as the result of noise, dust, fumes, or other disturbances. The M2 (Heavy Industrial) zone will be characterized by the location of open and enclosed manufacturing, processing, and assembly uses which may potentially create hazards, nuisances, or disturbances. These uses will be located in areas which will reduce the effects of these characteristics upon other areas of the community, and in an environment which is attractive but which recognizes the characteristics of the permitted uses. Some peripheral landscaping will be provided, where appropriate, to reduce the effects of the detrimental characteristics of permitted uses, and to enhance the appearance of the entire M2 zone.
