The City of Whitehorse is getting ready for the spring freshet season and the potential risk of landslides in the downtown area. Officials highlight similarities between this year’s snowpack and that of 2022 when landslides caused road closures and endangered homes along Robert Service Way.
Robert Dickson, the manager of engineering services for the city, identifies high-risk zones stretching from Takhini through Robert Service Way to the south access road. He assures residents that the airport operations are not likely to be significantly impacted by any major events.
Monitoring the melt rate closely, Dickson mentions the gradual pace so far but warns of potential rapid acceleration with warmer temperatures leading to debris movements along the escarpment, especially in exposed areas. The city team has reinforced monitoring efforts by installing additional sensors and increasing geotechnical inspections in critical locations.
In terms of emergency response, Ursula Geisler, the city’s emergency manager, emphasizes the importance of property owners in high- and moderate-risk zones being informed to plan for potential hazards. Residents are urged to have a 72-hour emergency kit ready, akin to packing for a three-day camping trip. Geisler also advises residents to arrange alternative accommodations in case of evacuation.
Communication strategies include updates through local radio broadcasts, social media, and the Yukon Government’s Alert Ready system, ensuring residents receive timely information. Geisler mentions door-to-door notifications and collaboration with partner agencies to support residents during evacuations.
While addressing immediate threats, the city is exploring long-term solutions, backed by a $45 million federal grant received in 2024. Dickson reveals ongoing discussions on reshaping the escarpment to enhance resilience, potentially promoting vegetative growth to stabilize the soil. Precautionary measures near Robert Service Way have been implemented, such as concrete slabs installation and road closure gates during heightened landslide risks.
