A Unified Development Ordinance (UDO) combines zoning regulations and subdivision regulations, as well as other Village regulations such as design guidelines, sign regulations, and stormwater regulations into a single document. Zoning, which provides the foundation for the UDO, is a tool used to enforce planning decisions that can regulate the look and feel of an area, promote or restrict certain uses, and promote public health, safety, and welfare. With the completion of the Village Comprehensive Plan Update in 2016, a directive of the Plan was to update zoning, subdivision, fence and sign regulations for clear and modernized standards and efficient administrative processes. The Village worked with a consultant on the project, Houseal Lavigne Associates, LLC (HLA), from early 2019 through early 2021 on the UDO project. A timeline is listed below.

In May 2021, the Village Board adopted the UDO and updated zoning map, which went into effect July 1, 2021.

The following useful handouts and resources have also been prepared:
