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.

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.
