Walnut Street Water Main Replacement & Storm Sewer Improvement Project

The City of St. Charles is pleased to inform you that Walnut Street from S. 19th Street to S. 17th Street is being reconstructed. The project will replace aging water main, improve stormwater drainage and replaces the roadway. Also, as part of the project new water services will be installed on S. 14th Street from Rte. 64 to Indiana Street and on the South side of Main Street from S. 14th Street to S. 19th Street.


The contract for this work has been awarded to Mauro Sewer of Des Plaines, IL. Fehr Graham, Inc. will be the on-site engineer performing construction inspections and acting as the field liaison to residents and property owners.  Any questions or concerns may be directed to City of St Charles Public Works at (630) 377-4405.


We are working with the contractor to determine the exact dates, but generally anticipate construction to occur as follows:

  • NICOR Gas Main Relocation – Week of February 14th  
  • Mobilization, Traffic Control Setup – Week of February 21st
  • Water Main and Stormwater Construction – February 23 – April 22nd
  • Concrete and Asphalt Removal and Replacement – April 25th – May 20th
  • Landscaping & Final Restoration – May 23rd – May 31st
  • Project Completion Date – June 5th


This project has been divided into three phases to facilitate the completion of the project in a timely manner and with as little disruption to residents and properties as possible:

Phase I: As part of the project, NICOR will need to relocate a couple gas mains. The NICOR team will have their own representatives coordinating all of this work. Once Nicor has completed the gas main replacements, the City contractor will start.

Phase II: Water Main and Stormwater construction includes removal of sections of the roadway, some driveway approaches, curb, and sidewalks. During this phase, the site engineer will provide notification to the impacted home or business.  Please relocate your cars to available parking areas or adjacent side streets by 7:00 AM. Access can resume when the barricades are removed from your driveway.

The City will be coordinating scheduled water shutoffs with impacted customers as part of this project. This will include a door notification of the expected shut down time and dates. The City will make every effort to schedule all water main shutdowns; however, the contractor is replacing a deteriorating water main and unexpected water main breaks can occur, resulting in an emergency water main shutdown.  

With the new water main construction, some water service lines will need to be relocated. The site engineer will be coordinating the replacement of water service lines including any required access.

Phase III: Concrete replacement work includes framing and pouring new curb, sidewalks and concrete aprons.  Please note if you have an existing concrete apron, curb and gutter in front of your driveway, and/or sidewalk across your driveway that is being removed and replaced you will not have driveway access for 3 days (from the date that the concrete is poured).  Please relocate your cars to available parking areas on your street or adjacent side streets by 7:00 AM.  Residents will be notified prior to loss of driveway access.  Access can resume when the barricades are removed from your driveway.

Phase IV: Street reconstruction work includes pavement milling, new asphalt pavement, and asphalt driveway replacements.  This phase will begin as soon as the concrete in the previous phase has gained sufficient strength to support construction equipment.  It is anticipated that you will have access to your property at all times during this phase.  However, due to the limited space and the moving construction process, access to your property may be delayed at times.  Please allow ample time for relocation of your vehicle and for temporary delays that may occur.  To assure that work is performed in a timely manner, please do not park vehicles on the Street, or within 30 feet of the Street on side streets during construction hours 7:00 AM – 4:00 PM. 

Phase V:  The third phase will involve parkway restoration.  All areas disturbed by construction will be restored. A recommended seed maintenance and watering schedule will be available on the project website.

Due to the scope, complexity, and nature of this work, as well as the unpredictability of weather, some delays and disruptions may occur.  There may be times when no work is occurring on your street. We ask for your understanding during these times; work is being coordinated and anticipated to be finished by the completion date of June 5th.  All work is weather dependent.


Please note that all work will be performed within the City right-of-way.  If you have any type of existing features within the City right-of-way area (i.e. sprinkler system, landscape features, special decorative rocks, brick driveways, electronic “invisible” dog fence, etc.), precautions should be taken by you, the homeowner, to remove or store these items right away to assure that they are not damaged. The City will not repair or replace private appurtenances left within the City right-of-way.


Mail and Garbage service will not be interrupted during construction.  Please leave your garbage at the end of your driveway on your normally scheduled pick up day by 6 am as pick may occur earlier than normal to avoid the construction work.


If you have any questions, please feel free to contact Public Works at (630) 377-4405 or via email twilson@stcharlesil.gov.
