Reducing Impacts to the Park
The new valve chamber in Second Narrows Park has been designed to fit into the park as seamlessly as possible; this includes the valve chamber being set into the existing landscape and the installation of a sloping green roof.
Tree removal will be required to accommodate construction. The majority of vegetation removal required for this project consists of shrubs and invasive species such as blackberry bushes and knotweed.
Once construction is complete, this site will undergo a full restoration. This includes the implementation of a re planting program and landscaping of any disturbed areas with native plants and species.
Trans Canada Trail
The Trans Canada Trail will remain open for the duration of construction.
The existing access road that is used for utility maintenance, sometimes known as the Upper Trail, will be closed for the entire construction period. This road was initially built to conduct maintenance on the existing water and sewer infrastructure that is located in and around the park.
Metro Vancouver recognizes the current recreational use of the access road and will ensure that it is restored to similar or better condition after construction.
Traffic Impacts and Noise
The entry shaft will be located in an industrial area in the District of North Vancouver; this is where the majority of construction, including the removal of excavated ground material, will take place. In an effort to reduce truck traffic, ground material excavated from this entry shaft will be transported to a disposal facility by barge.
In meeting with local residents, Metro Vancouver heard that noise was a concern and will ensure that noise mitigation measures will be in place during construction. In addition, noise studies have been completed to ensure that all work will comply with City of Burnaby’s bylaws or granted bylaw variances.
