Planning and Development

The Planning and Development Department is responsible for the current and future physical development of the City. Using O'Fallon's Municipal Code and the 2015 Update to the City's Comprehensive Plan, which was originally completed in 2008, staff, with the assistance of the the Planning and Zoning Commission, Board of Adjustment and City Council, implements planning goals and principles to create a community that offers better choices for where and how our citizens live.

Important information on the proposed Downtown Overlay Plan
  • The O’Fallon City Council and City Staff have been exploring options on how best to encourage growth and appropriate development in the Downtown area while also preserving property values and the area’s unique history. Council members and staff recognized during its review the need to develop a new zoning classification that takes into account the smaller lot sizes, grid street layouts, and the unique buildings and homes within the oldest portions of our community. As a result, the Planning and Zoning Commission and the City Council will soon be considering the creation of a “Downtown Overlay District”. This district would allow for specific zoning regulations to be put in place that are more appropriate for this historically significant and economically important part of our community. The following exhibits provide some information on the proposed Overlay Plan:

Planning staff's responsibilities include the review of all land development plans, as well as issues relating to the City's zoning and other land use ordinances. The Department also has personnel involved in the creation and maintenance of the City's GIS-based computer mapping programs. The GIS Division also provides support to other departments.
