We are doing wildfire fuel management along Highway 99 near Alpine Meadows area. Expect detours on the Valley Trail in these areas. There will also be minor delays and intermittent single-lane alternating traffic on the highway from 7 a.m. to 4 p.m. on weekdays.
Fuel management in Whistler
The Resort Municipality of Whistler has been conducting wildfire vegetation management projects on Crown and municipal lands since 2004 to reduce the risk of wildfire to our community. The primary goal is to reduce forest fuel loads within the wildland-urban interface to reduce the ability of fire to spread from the forest into the community and vice versa, and to make wildfires easier to fight. Fuel thinning will be discontinued when the fire hazard goes to extreme and will resume when the fire hazard is lower.
Sometimes projects need to burn some of the wood debris. We will alert the public through social media. There is no need to report smoke from fuel thinning projects.
Current projects
Wildfire fuel management along Highway 99 near Alpine Meadows
We are managing vegetation to reduce wildfire risk along Highway 99 in treatment area TU-1B in the Alpine Meadows area.
Expect detours on the Valley Trail in these areas. There will also be minor delays and intermittent single-lane alternating traffic on the highway from 7 a.m. to 4 p.m. on weekdays.
This project is part of our wildfire mitigation work and reduces wildfire risk along Highway 99 — Whistler’s key transportation corridor and primary evacuation route.
Work will conclude for the season once there is significant snowfall in the valley.
TU-1B
For the area in Zone C by the Crazy Canuck Dr (Rainbow subdivision entrance), there will be flaggers on the Valley Trail to conduct short intermittent closures as needed.
Further, the table below provides an estimated timeline for the work in each zone – please note this timeline is an estimate only and will cease when snow starts to stick.
- Zone A: Nov. 13 to Nov. 17
- Zone D – Nov. 17 to Dec. 5
- Zone C – Dec. 5 to Dec. 19

Process and goals
Vegetation management focuses on leaving mature and deciduous trees, while removing ground brush and debris, pruning lower branches, and removing tight, unmanaged second growth trees. This is accomplished by:
- Reducing the number of trees in the stand to open the upper tree canopy and reduce ability of fire to move from tree to tree;
- Focusing on removal of small diameter trees and retaining fire-resistant species such as old growth, Douglas-fir and deciduous trees;
- Reduce fine woody surface debris, while retaining larger coarse woody debris for habitat and soil productivity;
- Pruning trees to reduce ladder fuels between the ground and the forest crown; and
- Removing dangerous trees to protect workers, while maintaining high value wildlife trees where possible.
In addition to reducing forest fuel loads, secondary objectives are to protect critical infrastructure and facilities in Whistler, restore open forest conditions and demonstrate the principles and practices of the FireSmart program.
Fuel breaks
The RMOW completed a study in 2012 which was incorporated into the Community Wildfire Resiliency Plan (PDF) to identify where landscape level fuel breaks should be created along forest service roads around Whistler. The focus is on reducing tree densities in unmanaged second growth, rather than removing old growth or deciduous trees. Thinning stands within 100 – 200 m of each side of the road reduces the fuel available to feed fire growth and creates safer, defensible areas for firefighting crews to work in.
