Why this work is happening
The existing underground primary cables in this subdivision are nearing the end of their usable service life. Replacing this infrastructure will help maintain a reliable electricity supply and reduce the likelihood of future outages.
What work is included
This project includes several upgrades to underground electrical infrastructure across the subdivision, including:
Installation of approximately 7,355 metres of new directional drilled conduit and new high-voltage cable
Abandonment of roughly 10,500 metres of existing direct-buried primary cable that has reached the end of its life
Installation of new primary cable terminations and fault indicators
Replacement of three-phase primary cable and riser supplying Load Center LC3163
Replacement of several single-phase cable risers
Relocation of three pad-mounted transformers from rear yards to boulevard locations
Installation of secondary pedestals and upgraded secondary cable connections for improved reliability
Directional drilling will be used throughout most of the project to minimize surface disruption while installing new conduit and cables.
What residents can expect during construction
Traffic, parking, and access
Construction equipment and materials may be temporarily staged in the neighbourhood.
Temporary lane restrictions or short-term driveway access changes may occur in active work areas.
Traffic and pedestrian control measures will follow provincial safety standards.
Noise and vibration
Directional drilling, excavation, and electrical construction activities may create intermittent noise and vibration near work areas.
Power interruptions
Some brief planned power outages may be required to safely connect new equipment and cables. Property owners will receive at least 48 hours’ notice before any planned outages.
Trees, landscaping, and restoration
Some tree trimming or landscaping work may be required to allow safe construction and equipment access.
Contractors will restore disturbed areas such as lawns, asphalt, and concrete once construction activities are complete.
