The Zoning Code repeal and recreation of 2006 created special overlay zoning districts known as "design guide overlay districts." The design guide overlay districts shall be mapped as their originally approved borders. A design guide overlay district does become a part of the Zoning Ordinance and mapping when it is adopted by the Common Council as part of Chapter 380, Comprehensive Plan, of the City's Code, deeming it necessary to promote the public health, safety, morals and welfare, and further expresses the concepts, rationale and intent employed by the Plan Commission and planning staff when applying this chapter, deeming it necessary to promote the health, safety, morals and welfare.

When a property is within a design guide overlay district certain restrictions can apply regarding the development and redevelopment of the property subject to Plan Commission approvals. The adopted documents governing the specified geographic areas are found in the City of Muskego Public Works and Development Department and are subject to amendment from time to time by the City Plan Commission and Common Council.

The general purpose of a design guide is to aide the planning staff and Plan Commission in planning, design, and redesign of the built environment of the City of Muskego so as to enhance its visual character and avoid monotony. These standards will also assist in fostering sound, functional, attractive and quality development. The provisions shall be liberally construed in favor of the City and shall be considered as minimum standards.
