Minimizing impacts
Work hours
- Monday – Saturday: 7 a.m. – 10 p.m.
- Sundays and holidays: 9 a.m. – 10 p.m.
Overnight work, authorized by Alberta Transportation, may be required to limit impacts and improve public safety.
Dust mitigation
Dust will be monitored during construction. Mitigation measures may include:
- Watering
- Dust suppressant products
- Hydroseeding (a planting process that sprays a mixture of seed and mulch on surfaces to minimize dust)
Weed control
Seeded areas will be mowed twice per year and noxious weeds will be removed throughout the project.
Gravel extraction
Steps will be taken to address residents’ concerns and minimize impacts:
- Gravel for the WCRR project will be removed and hauled off-site for processing (crushing). After processing, it will be hauled back to the site for use.
- Noise and air quality will be continuously monitored and if conditions exceed established limits, appropriate action will be taken.
- Where practical, an earth berm will be constructed between the gravel extraction area and adjacent residences to minimize dust and noise impacts.
- Where practical, the existing vegetation will be retained as a buffer between the berm and the community. Additional trees may be planted.
- The berm and stockpile areas will be seeded, watered or have dust suppressant products applied to minimize erosion and dust.
On-site gravel extraction provides several benefits as well:
- Reduced number and frequency of trucks using public roads to haul gravel, improving safety and reducing noise
- Excavation will lower the road elevation, reducing noise and visual impacts for nearby residents
- Using gravel from the site reduces construction cost
- Gravel is a non-renewable resource and this deposit would be difficult to access after road construction is complete
