Project description

The Penny Green Subdivision Street Reconstruction Project will completely reconstruct 85% of the subdivision. The road is past its useful life, and typical preventative maintenance strategies, such as mill and overlays, are no longer cost-effective due to how quickly these strategies fail.

This project will consist of several utility modifications and upgrades. This utility work will not be completed by the City or its contractor. The City and its contractor will then complete removal of the roadway, subgrade modifications, spot replacement of sidewalk and curb and gutter, streetlight upgrades, and new asphalt pavement.

Current status

Over the past couple months, WaterOne, Kansas Gas, Google and other utilities and their contractors have been in the area relocating and renewing their infrastructure. The major utility work is nearing completion, and the City and its contractor is preparing to start work.

The City has awarded the project to G-B Construction, which plans to start work  Monday, June 17, 2024. The first major item of work is to remove and replace sidewalk, curb and gutter throughout the neighborhood. The contractor plans to remove and place back the concrete on one side of the road first. Once complete, they will move to the other side of the road. They estimate four weeks to remove and replace all the concrete throughout the neighborhood. If curb and gutter is scheduled to be removed in front of your driveway, expect the contractor to reach out and coordinate the removal and replacement of concrete with you. Street lighting work will also start and be ongoing for the majority of the project.

Once the concrete work is complete, the street reconstruction portion of the project will commence. Expect this work to startup in mid-July 2024.

Project phasing

The phasing plan below is for the street reconstruction portion of the City’s project. This is the portion where the roadway is being completely removed and new base and asphalt material are being placed. 

During this process, there may be sporadic concrete work and street lighting work occurring in other areas of the projects. Additionally, the utility work is scheduled from March to May will not follow this phasing plan.

Reasons for complete reconstruction

The City and its consultant have reviewed the asphalt and underlying base material (subgrade) on all the streets throughout the Penny Green Subdivision. 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. This leads to some spot failures but is not the main reason for issues along the roadway. The apparent issue is more closely 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. 

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.
