The Falcon Ridges Estates (Deer Run) Subdivision Street Reconstruction Project will completely reconstruct a substantial portion of the subdivision. In these areas, the roadway has deteriorated to a level where typical preventative maintenance strategies, such as mill and overlays, are no longer cost-effective due to how quickly the strategies will fail.

This project will consist of minor utility modifications, and these modifications will be completed by outside contractors and agencies.  It will also consist of the complete removal of the roadway, subgrade modifications at the 96th Street entrance, Deer Run Street to north of the entrance, and 95th Terrace. Also, both turnarounds on the streets on the south side of the subdivision will be reconstructed. Major curb and gutter replacement will occur and minor sidewalk replacement, and the entire area will receive an asphalt overlay at the end of the project.

The City and its consultant have reviewed the asphalt and underlying base material (subgrade) on all the streets throughout the subdivision. In areas identified for complete reconstruction, the team found that the subgrade soils consist of low-density and moist cohesive material, which will often lead to a soft, wet and weak subgrade. The remaining areas did not show these same issues, and spot pavement patching and a 2-inch mill and overlay will meet the needs of the roadway.  

When soft, wet and weak subgrade is the underlying cause of a failing road, 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. Installing underdrains will prevent the water intrusion issues that caused the subgrade to weaken.
