Preventative Maintenance Projects
Annually, we identify locations throughout our trail system to perform preventative maintenance projects to extend the life of the trails, parking lots and roadways. See the 2020 project map for construction locations and tentative schedules. The type of projects and anticipated impacts include:
- Microsurfacing: This work involves installing a thin surface layer to seal the existing pavement. The work requires the trail to be closed for a few days to allow the material to dry. Drying time can vary on an individual trail segment, so a trail will typically remain closed until the entire segment is dry. A trail repair project typically occurs one month before a microsurfacing project to correct surface deficiencies.
- Trail Repair: This includes repairing/filling cracks and patching or replacing the concrete and bituminous surfaces with deficiencies. Trails and other areas remain open during this work, but it is best to use caution when approaching the construction.
- Chip Seal: This work involves coating the surface with an emulsion product followed by installing small aggregate. Once the aggregate is embedded into the emulsion, the excess material is removed and the pavement is reopened to users. Final sweeping of the chips occurs 2-3 weeks after installation.
- Striping: Restriping of surfaces occurs after microsurfacing, chip seal and in areas where larger pavement sections have been repaired. Parking lots will be temporarily closed during installation. Trails and roads will remain open to users.
