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. 24, 2025

Next week will be very busy, especially on the east side of the subdivision. To avoid delays, please plan to exit on the west side via 92nd Terrace.

Concrete operations: Concrete work will be mostly complete by the end of Monday.  Crews will be placing sidewalk along Cottonwood Street and other small locations throughout the subdivision.

Street reconstruction: Street reconstruction will resume on Monday, Oct. 27, focusing on completing Phase 5 and beginning Phase 6(PDF, 870KB).

On Monday they will place the middle section of asphalt on:

• 93rd Street (from Widmer Road to Park Street)
• Rene Street (north of 93rd Street)
• Middle section of asphalt on Summit Street (north of 91st Terrace) 

Phase 6 will then begin in sections to allow better access to the east side. The first section will be:

• Widmer Road (from the Lakeview Village Entrance to just north of Cottonwood Street)

Once that section is complete, crews will finish the street reconstruction portion of the project on:

• Cottonwood Street (from 93rd Terrace to Widmer Road)
• Widmer Road (from Cottonwood Street to Santa Fe Trail Drive)

In total and weather pending, this work is expected to last about one week.  

• 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: Streetlight installation will continue into next week. The goal is to have all the new streetlights on by Halloween.

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.
