1. Who is responsible for the various roads in the county?

The County Highway Department is responsible for maintenance of public roads in the unincorporated areas of St. Charles that are not under the control of the Missouri Department of Transportation (MoDOT) or the local municipalities. MoDOT controls any lettered or numbered route (Route A, Route DD, Route F, Hwy. 79, Hwy. 94, etc.). The local cities control any roadways within their municipal boundaries.

2. How do I request a new stop sign to be installed in my neighborhood?

Any request for stop signs, no parking areas, traffic calming, or other traffic regulations must be submitted to the County Highway Department, along with a petition that includes adult signatures of residents from at least 15 separate households within the subject subdivision or representing a minimum of 51% of all property owners within one mile of the requested location that support the requested regulation. Once the petition is received, a traffic study will be performed and the results reviewed by the County Engineer to determine if the necessary warrants have been met to justify approval of the request. Any approval that would result in a new or revised traffic regulation will be publicly posted on the County’s website and in two conspicuous places no more than 500 feet from the applicable area of the proposed regulation. Within 60 days of the public notice, the County Executive may forward the County Engineer’s determination to the County Council for placement on the County Council’s Consent Agenda. At that meeting, the County Council shall hold a public hearing on the new or revised traffic regulations. The County Council then decides if the requested regulation shall be approved.

Any petitioner whose petition is denied, or approved with modifications, or any individual who resides within one mile of the requested location who believes himself to be aggrieved by the determination of the County Engineer, may appeal such determination to the County Council within 30 days following notice of the determination of the County Engineer. The appeal shall state in what manner the determination of the County Engineer aggrieves him. Upon receipt of an appeal, the County Council will add a hearing to its agenda in the normal form and fashion. It shall require the affirmative vote of four County Council members to overturn the determination of the County Engineer.

3. When it snows, when can I expect a snow plow to come to my street?

The County has a set procedure for responding to winter storms. In an effort to provide the most benefit for the most motorists, the first priority is to clear the arterial (main) roads first. Once those roadways are properly cleared, the snow removal trucks will move to the main subdivision streets. Attention is then turned to the secondary subdivision streets, and finally the cul de sacs. The actual time it takes to get to a particular street depends on many factors, including the severity of the storm, the type of precipitation, the temperatures, etc. If the conditions warrant, County Highway Department crews will work around the clock, using 12-hour shifts.

Permits to work in the right-of-way in unincorporated county can be obtained from the St. Charles County Highway Department by calling 636-949-7305.
