   Heavy Industrial	M2	AA Industrial

2. Purposes. Wauwatosa's industrial zoning districts are primarily intended to accommodate and promote industrial, manufacturing and employment-generating uses.
   1. Light Industrial. The M1 district is primarily intended to accommodate low-impact industrial uses and industrial park developments that have few if any visual or operational impacts.
   2. Heavy Industrial. The M2 district is primarily intended to accommodate high-impact industrial uses in locations that will not cause adverse impacts on residential uses.

Principal uses are allowed in industrial zoning districts in accordance with the use table of Section 24.07.030.

1. General. This section establishes basic lot and building regulations that apply in M districts. These regulations offer certainty for property owners, developers and neighbors about the limits of what is allowed; they are not to be construed as a guarantee that maximum allowed densities and development yields can be achieved on every lot. Other factors, such as topography, the presence of floodplains or protected resources, off-street parking, landscaping requirements and other factors may work to further limit actual development potential.
2. Basic Standards. The lot and building standards of the following table apply to all principal and accessory uses allowed in M districts, except as otherwise expressly stated in this zoning ordinance. General exceptions to these standards and rules for measuring compliance can be found in Section 24.18.030.
