• On Tuesday, August 2, O'Fallon voters will be asked to decide on a ballot issue that could help to shape the future of O'Fallon's parks: Proposition PARKS. If approved by the voters, this proposition will allow the City of O'Fallon to issue bonds for the construction of an expanded Alligator’s Creek Aquatic Center and the construction of a brand new passive park off of Highway DD called O’Day Park. Learn more about Prop PARKS.

Gateway Green Light Program Aims to Improve Signal Timing

Everyone hates sitting at red lights for long periods of time. A new program is aiming to improve how traffic signals across St. Charles County work together and you can have a say in what improvements are made.

The Gateway Green Light (GGL) program is a cooperative effort between the cities of Cottleville, Dardenne Prairie, Lake Saint Louis, O'Fallon, Saint Charles, Saint Peters, Weldon Spring, Wentzville, as well as the Missouri Department of Transportation and St. Charles County, to improve traffic signal operations. The program actively manages and monitors traffic signal operations in real time, especially those that cross municipal boundaries, reducing unnecessary delays and improving traffic flow while reducing emissions that contribute to ozone pollution. The program seeks to provide motorists real-time information on roadway conditions and travel times through the use of dynamic message boards and travel time detectors installed in upcoming construction phases. As the infrastructure continues to expand, benefits to the public will continue to increase. We ask that you complete the 20-question survey by clicking on this link below to help identify areas we can focus our efforts on.

An easy way you can support Meals on Wheels

The O'Fallon City Council introduced a new donation program allowing residents to help a local charity when they pay their City water/sewer or trash collection bills. Each year the Council will designate which charity is to receive the funds. The Meals on Wheels program was chosen for 2016. Residents must sign up for the program by sending a note with their signature to O’Fallon’s Utility Billing requesting to donate their choice of $1, $3 or $5 to the charity. The donation will be added to their bi-monthly bill. For more information about O’Fallon’s new donation program call 636-379-5488 or email kpieper@ofallon.mo.us.
