The Engineering Department’s goal is to provide the City with professional engineering services that ensure long-range comprehensive planning, sound project design, quality construction management and maintenance of the City’s infrastructure. To that end, this Department offers technical engineering support to a variety of City departments, confirms sound engineering principles are applied, certifies ordinance requirements are met, prepares and executes Capital Improvement Projects, and issues permits to the public. In addition, the Department also administers the Sewer Lateral Program for the City, issues Commercial Trash Permits, and keeps track of all records related to projects for the City.
OUR GOAL IS TO PROVIDE THE CITY WITH PROFESSIONAL ENGINEERING SERVICES THAT ENSURE LONG-RANGE COMPREHENSIVE PLANNING, SOUND PROJECT DESIGN, QUALITY CONSTRUCTION MANAGEMENT AND MAINTENANCE OF THE CITY’S INFRASTRUCTURE.
The Engineering Department is divided into three groups, the Project Management Group, the Development Group and the Construction Inspection Group. Each of these groups plays a critical role in ensuring that City Projects, including capital projects as well as commercial and residential developments are designed and constructed properly and safely. Furthermore, within each group are subgroups including the Traffic Management Group, the Plan Review Group, and the Stormwater Management Group The Engineering Department also aids with snow removal during winter weather events and remains ready to provide emergency response in the event of a significant disaster. In total, this Department has more than 600 years combined experience in their respective fields.

In 2025, we had several new employees start in the Engineering Department and their knowledge, effort and positive attitudes were a welcome addition to the team. They have meshed very well, and they will continue to play a vital role in the success of the Department. These employees are: Todd Artz – Assistant Director of Engineering, Brian Spalding – Construction Inspector I, and Dustin Robinson – Construction Inspector I. Additionally, some Engineering Department employees took new positions. These employees are: T.J. Kelley – Construction Inspection Manager and Steve Meyers – Construction Inspection Supervisor. In addition, Scott Schneiderheinze – Construction Inspector II has completed his training and has earned his UAS (Unmanned Aircraft Systems) Drone License. The end result will provide the City with more knowledgeable inspectors and work monitoring capabilities working throughout the City with the common goal of providing better-built developments with reliable City infrastructure for our residents, guests and businesses.
The Traffic Group consists of the Traffic Signal Technician and Assistant Director of Engineering. The Traffic Management Group handles all of the traffic-related requests and maintenance of the signal infrastructure/city-owned lights within the City of O’Fallon. Each year, City residents make requests and inquiries regarding various traffic and safety concerns, including traffic calming, signal and stop sign warrant studies, crosswalk installation requests, etc. These items, and their required processes are handled by this group. The Traffic Group works hand-in-hand with other departments to ensure the safety and well-being of our residents as they travel the roadways of the City.
Each year, the Traffic Signal Technician maintains, monitors, and repairs all of the City-owned traffic signals and streetlights while working in conjunction with MoDOT and St. Charles County to share resources where possible. This helps to keep the traffic flowing safely throughout the City. In 2025, the following repairs were made:
• 39 traffic signals operated and maintained by the City.
• 470 total traffic signal repairs were made, including replacing deficient LED lights, etc.
• 45 streetlight repairs of lamps were made that are owned and operated by the City
• 20+ traffic calming/no parking/stop sign/crosswalks/speed and volume traffic studies were conducted.
• 446 utility locate requests were fulfilled.
By accomplishing these tasks, the City’s infrastructure is maintained so the residents can commute safely and efficiently throughout the City.
As part of the Chapter 405 City Code updates completed in 2023, the Traffic Calming Policy was substantially revised to include several changes to the existing process. As in previous years, the City continues to see a large volume of requests for traffic calming evaluations throughout the City. In 2025 new Traffic Calming installations were performed in existing neighborhoods, two dips and one island were installed on Turtle Creek Drive.




Below is the breakdown for the Traffic Expenses in 2025 The budget for traffic related expenses fall into different general categories, including the ones shown in the pie chart below. Large portions of the expenses fall into the categories of traffic calming and signal system and hardware. 34,483.00 18,743.00

The Construction Inspection Group performs all field inspections related to infrastructure items for residential sites, commercial sites and capital improvement projects. These inspections include:
• Roadway pavement
• Sanitary sewers
• Site grading
• Commercial parking areas
• Utility and excavation permits
• Individual lots within residential developments
• Bike/Trail projects
• Park projects
• As built plans
• Storm sewers
• Water mains
• Common ground amenities in subdivisions
• Residential Development
• Residential and commercial driveways
• Commercial site development
• Stormwater projects
• Facility projects
• Review of concrete and asphalt tests report
The Construction Inspection Group uses the online permitting system CitizenServe for inputting inspections and issuing reports directly from the software platform. The ability to access a site’ s document files from the field without the need to connect to the City’ s FileShare server has lessened the need for trips into the office throughout the day for paperwork. The group continues to develop procedures to best utilize the CitizenServe System to meet communication needs with contractors and developers.
In 2025, there was a significant amount of new pavement and other infrastructure placed throughout the city. There were additions to existing subdivisions for new streets including areas within Harvest at Hopewell on the South and Brookside Addition on the North. Along with these subdivisions, streets were added in two brand new subdivisions, Post Farms off Highway N and Strawberry Farms off Mexico Rd. Within these four subdivisions, alone, 6.4 new lane miles of concrete pavement or 49,350 SY were added to the city infrastructure. Aside from the new pavement, there were new water lines, storm sewer lines and sanitary sewer lines placed within these same subdivisions. The subdivisions in the northern part of town will see all these infrastructure items become city assets. While the subdivision in the southern part of the city will only have storm sewers and streets becoming city assets in the future.
Along with these improvements, the Construction Inspection group also inspected several Capital Improvement Projects (CIP) including the annual Concrete Program, the annual Asphalt Program, a new program for Micro Surfacing asphalt pavement. Other CIP projects that were inspected by this group were the Annual Crack Seal Program, Path Maintenance, Partial Depth Joint Repairs (PDR),
Weldon Spring Phase I, K and N Intersection Improvements, the CASTLE site, Dardenne Greenway. All together our Construction Inspection group was responsible for inspecting over $18,700,000 worth of improvements and additional infrastructure within the City for 2025.
In addition to infrastructure repairs and improvements, the Construction Inspection group takes care of excavation permits and driveway permits. Excavation permits are a permit for a utility company, typically, that needs to repair or wants to install a new utility within the City of O’Fallon. This permit covers work in the City regardless of whether it is within City right-of-way or not. The excavation permit ensures that areas are restored to like condition, along with ensuring the protection of City owned assets. Driveway permits ensure that driveways that are repaired within the right-of-way meet City standards and specifications. In 2025, there were 363 excavation permits approved and 140 driveway permits approved.
The knowledge and experience of our Construction Inspectors ensures that O’Fallon’ s Developments and Capital Improvement Projects are constructed properly and meet the City’ s standards and specifications to ensure quality, long-lasting infrastructure.

The Construction Inspection group provided vital inspections for new and updated City infrastructure to include new storm sewer lines, retaining walls, pavement, lighting, signage and striping and other miscellaneous work to complete the project. They also assisted in coordinating with other utilities to facilitate relocations as needed to complete the project.
The Streets of Caledonia has several commercial sites within the development that were either started, completed, or are still in progress in 2025. SSM built a new medical building on the corner of Caledonia Parkway and Outer 40, this building opened in early 2025. Cambria Hotel received plan approval in early 2025 and began construction in the spring. First Community Credit Union opened at the corner of Hwy DD and Caledonia Parkway in summer of 2025.
All of these sites required multiple inspections and coordination with contractors from the dedicated group of inspectors. Our inspectors were there to ensure compliance with specifications from the initial clearing and grading to the installation of paved approaches, connecting these sites to City roadways.

This subdivision within the City of O’Fallon has 896 lots and is approximately 262 acres. There are public streets along with private alleys, common ground amenities and other improvements. In 2025, streets within phase 2 were paved. The construction inspection group performed many inspections for this development to ensure compliance with City standards and specifications prior to acceptance and dedication of the public improvements.

The Plan Review Group is responsible for the review of all residential and commercial site plans, grading plans, as-built plans, record plats, driveway applications and flood plain review. They provide information to the public and the Planning and Development Department on principles and codes for the City. They administer the Floodplain Management Program and the Community Rating System. Plan Review also assists residents, businesses, and other departments with respect to issues dealing with grading, development, and specific code issues.
The Plan Review Group continues to average a two-week project review time and strives to provide excellent customer service to all residents, engineers, developers, and contractors. The following chart shows the quantity of development permits that were reviewed, and the amount of revenue generated in 2025 from Plan Review.
The Plan Review Group was busy reviewing plans in 2025
The following are some photos depicting developments that were reviewed and approved Included are the developments St. Dominic High School Expansion, Quik Trip Main Street, Police Training Facility, Dutch Bros Coffee at Bryan Road Commercial Development, Apache Village RV, Bryan Road Sports Facility, Dardenne Dental Arts, etc. These projects and more were under construction or completed in 2025.



In addition, the Engineering Plan Review Group worked with Planning and Construction Inspection to review development sites before occupancy permits are issued to make sure that the constructed site conforms to City standards and matches what was proposed on the construction plans. This ensures that developments will deliver what was agreed upon in the planning and review process, especially when it comes to public infrastructure.

The Stormwater Management Coordinator is responsible for the City’s National Pollutant Discharge Elimination System Permit (NPDES) Regulations and Stormwater Management Plan as required by the Environmental Protection Agency (EPA) and Missouri Department of Natural Resources (MDNR). Part of the requirements entail performing public outreach and education sessions, public participation events, construction site runoff compliance, illicit discharge detection / elimination and a municipal pollution prevention and good housekeeping program. The coordinator addresses stormwater concerns from residents as well as drafts and implements policy/procedures to protect stormwater quality throughout the City. Additionally, the Stormwater Management Coordinator is tasked with inspecting 572 existing detention basins on a three-year rotation and more than 350 Best Management Practices (BMP’s) yearly









In 2025, Five Public Outreach and Stormwater Education Sessions were conducted with a total of 1300 participants. These events included presentations and stormwater activities at local schools and Public Works Fair



At the beginning of spring each year the City of O’Fallon comes together along with volunteers to clean up our local streams. In order to keep our streams healthy and clean throughout the City, it involves the residents’ help. This past year in 2025, with the help of nearly 125 volunteers we were able to pull an astonishing 1,800 lbs of debris from the creeks at just a couple locations We will strive to continue improving our cleaning next year and in the future. Not only is it important for aquatic life and animals who depend on these creeks to be clean, they are also used for recreational hobbies such as fishing, playing, and hiking. With the proper care and maintenance of these creeks and streams they will continue to thrive. City of O’Fallon water runoff can impact larger bodies of water downstream from Missouri/Mississippi River all the way to the Gulf of Mexico.

Project Management (PM), as a concept, is defined as a carefully planned and organized effort to accomplish a specific task or project. The Project Management Group is led by the Capital Improvements Manager. The City of O’Fallon, in order to better serve our residents, takes on and carries out several projects of varying size and end goals each year. These projects are varied and include new roadway construction, maintenance and rehabilitation of existing roadways, new building construction, building renovation construction, park projects, sidewalk projects, stormwater, etc. Each of the projects undertaken by the PM Group is done to improve the quality of life for the community. The goals of projects can include things like reducing the time it takes to drive through town, providing smoother and safer roadways and improving the City’s infrastructure based on future needs. Sometimes these projects require more funding than the City can provide. In these cases, the PM Group is responsible for aggressively pursuing additional funding and grants from other organizations. These additional sources of funding allow us to accomplish more projects for the City and its residents while minimizing the use of City funds.
Projects can be divided into distinct sections, where certain items need to be accomplished before moving to the next section. Typically, a project is composed of the following five (5) sections:
1. Pre-Project Planning: Includes developing a project plan, project scheduling, determination of critical path, applying for funding, if required, defining project goals and objectives, specifying tasks, identifying needed resources, and associating budgets and timelines for completion, etc.
2. Design: Includes the development of design specifications, obtaining permits, selection of design consultants, development, and approval of design drawings for construction, etc.
3. Right-of-Way: Includes the acquisition of any required right-of-way or easements from property owners in the vicinity of the project in order for the project to be constructed.
4. Utility Coordination: Includes the coordination with utility companies/entities which may have existing infrastructure which conflicts with the proposed construction. These utilities may need to be relocated or eliminated in order for the project to progress.
5. Construction: Includes the actual construction of the improvements and infrastructure.
Projects are tracked and administered by each Project Manager, and updates for each are posted for residents to view during the duration of a project. A full listof all City ProjectsadministeredbytheProject Management Division can be found and is maintained on the City’s website at O’Fallon Engineering Projects (arcgis.com) This website was officially launched on December 8, 2022, for the public’s use.

In total, the Project Management (PM) and Construction Inspection (CI) groups manage nearly 35 projects for the City at various phases of completion, with an estimated value of $60M - $70M annually.
