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
July 1, 2025:
Water main work – Water main and service installation along Mullen Road is now complete. Crews are currently addressing a leak that occurred during installation on 92nd Terrace between Mullen Road and Cottonwood Street. Once the repair is finished, service line installation will start on 92nd Terrace, and additional water main work will be completed on Cottonwood Street immediately south of 92nd Terrace.
Concrete operations – Concrete work is not scheduled for this week. Starting next week, the contractor plans to remove and replace the curb and gutter on the north side of 94th Terrace, 94th Street, and next to Green Prairie Park on 92nd Terrace. Removals are scheduled for Monday and Tuesday, with concrete placement scheduled for Wednesday. If your home is within this section of roadway, please note that driveway access will be temporarily unavailable during this work, and on-street parking may be necessary. Affected residents will receive door hangers with more detailed information.
Sidewalk installation is also scheduled to move forward next week, with a large portion of the sidewalk on 92nd Terrace and Widmer Road planned for placement the day after the curb work is completed.
Streetlight installation – By the end of the day, all streetlight conduit and base installation should be installed in areas south of 93rd Terrace. Work will continue through the rest of this week and into next week in the sections north of 93rd Terrace.
Summit Street – Kansas Gas is currently replacing their main along Summit Street and 91st Terrace. That work began last week and is expected to be completed by mid-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.
