PROJECT OVERVIEW
The City provides annual road maintenance to preserve and protect Island roadways. The Annual Roads Preservation program consists of two options each year:
- Grinding and patching roadways, or
- Chip sealing
The City determines which roads to repair based on the Pavement Condition Index (PCI) score and the amount of traffic.
Grinding and patching techniques provide a long-term solution for fixing uneven pavement or other defects in the road. When the roads are patched, it creates a smoother surface for driving. Grinding and patching extends the life of the road when a full road repair is not an option.
Chip sealing is the process of applying a coat of asphalt oil and finely crushed rock over the existing pavement. This restores the street surface to protect the roadway from water and weather damage. Chip sealing is a cost-effective way to extend the life of a road and save significant funds on future road repair costs.
Each year, the City invests an average of $650,000 in its street maintenance program. The budget includes roughly $400,000 from the Transportation Benefit Fund (TBF) revenues and the remainder is supported through the City’s General Fund.
2021 STATUS
The 2021 Annual Roads Program will consist of grind and overlay. Staff anticipates the advertisement for bids to go out this spring with construction to occur during the summer months.
During construction, local access will be maintained with intermittent delays. Detour routes will be posted. The list of roads for 2021 will be uploaded early summer.
