O'Fallon, MO Parking Rules: Snow Removal Parking Rules (2026)

010, enacted by Ord. No. 5689 in 2011 replacing the former Chapter 385 snow-emergency-route rules, declares that parked vehicles slow snow and ice removal, impede street clearing, and can delay emergency response during winter weather. Subsection (A)(1) makes the parking prohibition self-executing: it takes effect on all City streets automatically upon any accumulation of snow, ice or other frozen precipitation, with no need for the City to issue a separate emergency declaration first. Subsection (A)(2) governs when the ban lifts: it stays in effect until the Mayor or City Administrator announces termination, except that any individual street that becomes substantially clear of snow and ice for its entire block length is automatically excluded from the prohibition even before a citywide announcement.

030, which bars anyone except City-contracted crews from depositing cleared snow or ice back into streets, public ways, or against fire hydrants. 040 gives the Mayor or City Administrator authority to impose additional traffic and parking restrictions during any weather emergency, publicized via the City website, other media, and press releases to local broadcasters.
