As part of the Port Mann Highway 1 (PMH1) Improvement Project, important environmental and habitat work is taking place on‐and off‐corridor to deliver the project to the highest environmental standards. This work has four main components: Enhancement, Compensation, Construction timing, Protection/Restoration.
In Surrey, work is underway to create an enhanced stream channel at Hjorth Creek.
Hjorth Creek Environmental Enhancement
In June 2009, work began to create additional habitat at Hjorth Creek, a tributary of the Serpentine River. Planting continues in 2010, and once complete, this area will feature about 12,000 m2 of new aquatic habitat and about 21,000 m2 of new stream‐side habitat, including placement of large woody debris and in‐stream boulders for cover.
Installation of new culverts will improve fish and wildlife passage under Highway 1, and the existing creek flow will be diverted to the new and improved channel.
This additional channel will benefit young Coho Salmon, Cutthroat Trout, amphibians, small mammals and native wildlife.
