The list below provides more information on the construction projects scheduled for the 2026 season. These projects are part of our ongoing efforts to maintain and improve local infrastructure.
Asphalt Surface Rehabilitation
The City uses a Pavement Management System (PMS) to plan, design, construct, and maintain the road network. Every five years, Engineering completes a city-wide pavement condition survey that measures surface defects, cracking, and overall ride quality. The data is analyzed through the PMS to determine which road segments should be resurfaced or reconstructed.
Arterial and collector roads are prioritized because they carry the highest traffic volumes, connect major destinations, and have the greatest impact on overall network performance. Local residential streets are generally scheduled once their pavement condition has deteriorated further.
