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. 22, 2025:

Water main installation – The contractor has completed installation of the new water main and will finish the remaining tie-ins to the old main and all service lines installations over the next couple of weeks. Service line work will take place on 93rd Street, Cottonwood Street and Widmer Road.

Concrete operations – Concrete work will resume on Monday, Aug. 25. Crews will remove and replace curb and gutter at three main locations: 

• North side of 92nd Terrace (from just west of Mullen Road to Cottonwood Street)
• East side of Cottonwood Street (from 92nd Terrace to 93rd Terrace) 
• West side of Cottonwood Street (from 93rd Terrace to Old 95th Street)  

Removals are planned for Monday and Tuesday, with new concrete placed on Wednesday. Driveway access will be restored once the concrete has reached the required strength, which is anticipated by Friday afternoon.

Street reconstruction – Phase 2 of street reconstruction will be completed Monday, Aug. 25. This work will consist of paving the next 2 inches of asphalt. The final 2 inches will be placed near the end of the project.

Streetlight installation – All underground work is complete. Installation of new lights is planned for early October.

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.
