In 1998 Intrawest Placemaking redeveloped the Whistler Creekside Base and temporarily re-routed Whistler Creek. The creek remained in this temporary channel for over 10 years due to a pedestrian village development at Whistler Creekside and contamination from a nearby gas station.
Whistler Creek was finally returned to its original alignment in July 2011. This was a major development plan priority to ensure adequate flood hazard protection for adjacent residential dwellings. In addition to the new Whistler Creek channel, two debris barriers were constructed upstream of the Creekside Village development.
Construction of the re-routed Whistler Creek channel from Whistler Creekside was completed by 2003. Contamination from a nearby gas station was discovered in 2003, causing the creek diversion to be postponed until the site was remediated. Site remediation was complete by 2009 and the creek was returned to its original alignment in a new, flood flow engineered creek bed.
Cascade Environmental Resource Group Ltd. was the environmental consultant responsible for the entire multi-year project from project conception to completion. Services included permitting, construction monitoring and environmental mitigation, with the diversion of Whistler Creek in 2011 being the final task. In addition to preparing permit applications and liaising with government officials, Cascade assessed the riparian condition and made recommendations for improvement, conducted the fisheries salvage of the channel that was dewatered, and provided environmental monitoring during construction.
Cascade ensures that projects are conducted in accordance with permit requirements and instream best management practices.
