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
Aug. 11, 2025:
Water main installation continues along Widmer Road and will soon tie into the main already completed just east of the 92nd Terrace and Cottonwood Street Intersection. Once all main installation is complete, the contractor will proceed with the remaining service line installations along 93rd Street, Cottonwood Street and Widmer Road.
Concrete operations are scheduled to resume Aug. 12. Crews will remove and replace curb and gutter along the west side of Mullen Road (from Old 95th Street to 92nd Terrace), the north side of 93rd Terrace (from Mullen Road to Cottonwood Street), and east side of Cottonwood Street (from Old 95th Street to 93rd Terrace). Removals are planned for Tuesday and Wednesday, with new concrete placed on Thursday. Driveway access will be restored once the concrete has reached the required strength, which is anticipated by Saturday afternoon.
Phase 2 of the street reconstruction will start Monday, Aug. 18. This phase is expected to last approximately one week. Amino plans to remove the old roadway and place base rock on Mullen Road the first couple days with paving operations beginning shortly after.
Please note:
- During the day, driveway access may be limited. Please coordinate directly with the contractor regarding access needs.
- You may need to drive on gravel surfaces for a couple days, or longer if heavy rain occurs.
- In the evenings and overnight, temporary ramps will be placed to allow access to driveways.
Streetlight installation will be complete throughout the Green Prairie Subdivision by the end of Aug. 13.
Underground work for the streetlight installation on Summit Street is complete. The street reconstruction portion of Summit Street will be completed with a later phase of the Green Prairie Project.

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.
