All concrete placed within the City of O'Fallon must be submitted to and approved by the Eastern Missouri Pavement Consortium (EMPC). Approved mix designs will be stored on their website for use. Specifications for concrete pavement are also provided. Please reference the EMPC brochure (PDF) for additional information. Any new mix design that is submitted may take several weeks before approval is issued.

Excavation Permits (Who is digging near my yard?)
The City of O'Fallon requires a permit for all utility work and utility excavations within both private property and the City right-of-way. Previously, the City only required a permit for work within the right-of-way. However, due to the State passage of the 2007 Video Service Providers Act, a new City ordinance was established for the placement of video services on private property and extends regulatory authority to the placement of any utility facilities on private property.
Utility companies are constantly digging in new utility lines around the area. New lines for high-speed internet, telephone, fiber optics, cell phones, plus new gas lines and adjustments to water and electric lines cause contractors to open up the ground, install pits and boxes, and then install their utility. These are usually shorter projects and remain mostly in the grass areas.
More information on City ordinances for utilities on private property can be found in Section 400.910 of the Municipal Code; for utilities within the City right-of-way, please refer to Section 406 of the Muncipal Code.
For information regarding utility permits, please contact firstname.lastname@example.org or 636-379-5556.
