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

Oct. 10, 2025

Next week will be busy, especially on the east side of the subdivision. To avoid delays, please plan to exit on the west side using Old 95th Street or 92nd Terrace.

Concrete operations: Concrete work will resume on Monday, Oct. 13. Crews will remove and replace curb and gutter at the following locations: 

• East side of Widmer Road (from Santa Fe Trail Drive to 93rd Street
• East side of Cottonwood Street (from 93rd Terrace to Widmer Road)
• South side of 93rd Street (from Widmer Road to Rene Street)
• East side of Rene Street (north of 93rd Street)
• Various driveways, sidewalks and ADA ramps

Most removals will occur on Monday and Tuesday, with concrete placement on Wednesday. Driveway access will be restored once the concrete has reached the required strength, which is anticipated by Friday afternoon.

Street reconstruction: Street reconstruction will resume on Monday, Oct. 13. Work will occur at these locations:

• 93rd Street cul-de-sac (west of Cottonwood Street)
• 93rd Terrace (where Cottonwood Street splits for a couple hundred feet)
• Summit Street (north of 91st Terrace) 

This work is expected to last about one week. Amino plans to remove the old roadway and place base rock on Monday and Tuesday, followed by base asphalt Wednesday and Thursday.

Please note:

• During the day, driveway access will 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: Installation of new streetlights is expected to start late next week or early the following week.

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.
