In which zone is a junk yard classified as a permitted use?

A junk yard is typically classified as a permitted use in industrial zoning categories. The M2 zone, which is generally designated for heavy industrial activities, is appropriate for operations that may produce noise, emissions, or require large land areas, making it suitable for junk yards. These types of facilities often need to be located where they are not in close proximity to residential areas or light industrial uses to minimize negative impacts on nearby properties.

In contrast, the other options, such as M1, M3, and R1, represent different zoning classifications with M1 being for light industrial, M3 possibly indicating a more restrictive or specialized industrial use, and R1 typically designating residential areas where such uses would not be allowed at all. Therefore, the classification of the junk yard as a permitted use in the M2 zone aligns with its industrial nature, allowing for operations that can handle heavy machinery and manage bulk materials commonly found in junk yards.
