Transportation - Transportation planning and construction is vital to the growth and safety of the City of Cottleville. Cottleville follows St. Charles County standardsfor roadway construction and MoDOT access management guidlines, but other ordinances may apply depending upon the zoning district. Please contact Rob Mosbey rmosbey@cityofcottleville.com with specific questions related to Transportation within the City.

The City of Cottleville contracts with St. Charles County to provide maintenance and operation of most public improvements. However, any questions or concerns regarding a public works issue should be directed to Public Works at City Hall who will examine the situation and relay applicable information directly to St. Charles County.


Effective November 1, 2004, the City of Cottleville assumed responsibility for all plan reviews and all construction inspection of development within the corporate limits of the City. It is no longer necessary to submit plans to St. Charles County or coordinate inspections with St. Charles County, except for existing subdivisions currently under development, as St. Charles County will perform inspections until all improvements are completed.

Please continue to submit all plans and permit requests to Cottleville City Hall (5490 Fifth Street), including Special Use Permits for work to be completed in the existing public roadways.

To coordinate a construction inspection, please contact:
Rich Francis 636-498-6565
at least 48 hours before start of any construction identified on approved construction drawings. INSPECTIONS WILL BE REQUIRED BEFORE ACCEPTANCE OF ANY PUBLIC IMPROVEMENTS. Requests for escrow releases will be processed by Rich Francis in the same manner as St. Charles County releases. Developers will also be required to coordinate material testing services with a testing consultant approved by the City. Fees for all testing services will be charged to the developer on a monthly basis pursuant to Ordinance 580 and paid by the developer.
