How these numbers are made

Property tax: St. Charles County 2025 combination tax chart; the chart has no combined line for Dardenne Prairie, so the parts are the common county taxes, Fort Zumwalt R2 (4.1262), Wentzville fire district #13 (0.6507), the community college and the city rate of 0.0821 per $100, on 19% of the Census median home value. The city is split among school districts and fire districts, so other addresses differ.
Water: Public Water Supply District #2 lists a $23.77 monthly service availability charge plus a $0.16 state water fee and $7.46 per 1,000 gallons. The city lists Missouri American Water as the other water provider; which one serves an address depends on the address.
Sewer: Duckett Creek Sanitary District basic residential rate of $26.75 per month plus the $28 yearly lateral assessment on the county tax chart; the city also lists Public Water Sewer District #2 for some addresses.
Trash: Grace Hauling rate for the City of Dardenne Prairie from the O'Fallon January 2026 provider comparison chart ($15.76 trash and recycling; yard waste adds $7.88); the city page does not publish a rate.
Electricity and gas: Ameren Missouri 1(M) and Spire rates as for nearby St. Peters; Cuivre River Electric Coop. serves other addresses. No city utility tax or franchise percentage on energy bills was found.
Nothing here is legal, tax or insurance advice.
