Project description
The Green Prairie Subdivision Street Reconstruction Project will completely rebuild most streets within the subdivision, as well as a small section of Summit Street northeast of the area. The roads have exceeded their useful life, and traditional maintenance strategies, such as mill and overlays, are no longer effective due to rapid deterioration.
This project will also include significant utility upgrades. The City will work in partnership with WaterOne, which will upgrade a large section of water main as part of the project. Additional utility work will be handled by outside companies and contractors.
After the utility work is completed, the project will involve the removal of the existing roadway, installation of new water mains and water service connections, subgrade modifications, spot replacement of sidewalks and curbs, upgrades to streetlights, and installation of new asphalt pavement.

Current status
June 13, 2025:
Water Main Work - The tie-ins of the new water main to the old main took longer than anticipated but are on track to be completed along Mullen Road by the end of the day. Next week, crews will install the remainder of the water main on 92nd Terrace to Cottonwood Street. Once complete, they will move on to installing all the service lines on 92nd Terrace west of Cottonwood Street and on Mullen Road north of 94th Street.
Streetlight Installation - The streetlight subcontractor will start installation of streetlight conduit tomorrow. Work is scheduled to begin on 94th Terrace and 94th Street. This part of the project should move along fairly quickly.
Concrete Work - Beginning Monday, the contractor will start preparing for curb and gutter improvements. Removals are scheduled for Tuesday and Wednesday along the north side of 94th Terrace and south side of 94th Street, with installation planned for Friday. If your home is within this section of roadway, please note that driveway access may be temporarily restricted during construction, and you may need to park in the street. Affected residents will receive door hangers with more detailed information. Once work on one side of the street is complete, the contractor will switch to the opposite side to continue curb and gutter improvements.
Sidewalk replacement along 92nd Terrace and Widmer Road is currently scheduled for either the last week of June or first week of July.

Reasons for complete reconstruction
The City and its consultant have reviewed the asphalt and underlying base material (subgrade) on all the streets throughout the Green Prairie Subdivision. The leading issue is related to the asphalt pavement and base material that consists of a reclaimed aggregate base and a thin layer of asphalt. This thin layer of asphalt has not held up well over time. Additionally, the team found that the subgrade soils mostly consist of a well-compacted fill made of clay and sand with spot locations of overly saturated clay. The saturated clay locations leads to some spot failures but is not the main reason for issues along the roadway.
The best long-term strategy is to completely replace the roadway. This includes removing unsuitable soil, densifying the subgrade, installing an aggregate base, and finally installing the base and surface asphalt.
Frequently asked questions
When can I remove the flags in my yard?
The flags mark underground utilities and are essential for contractors performing investigation or relocation work. Removing them could result in utility disruptions for you or your neighbors. Please leave the flags in place and work around them if construction crews are in your area.
