Construction of this project is underway, with completion expected in 2025. While the duration of this project spans over six years, work at the south shaft site in Second Narrows Park will take place intermittently with some breaks between different construction activities.

Construction activities include:

• Shaft excavation and shoring
• Valve chamber and pipe installation
• Welding, backfilling and restoration

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.

Work will take place:

• Monday to Friday: 7:00 am to 8:00 pm
• Saturdays: 9:00 am to 8:00 pm

Crews may occasionally be required to work outside of bylaw hours; in these cases, advanced notice will be provided to residents. All work will comply with City of Burnaby’s bylaws or granted bylaw variances.

Metro Vancouver is committed to minimizing the impacts of construction on the community. Local residents and businesses will receive ongoing notifications through newsletters, web updates, email and on-site signage.

A community liaison has been assigned to this project and is available to address any public questions or concerns.

At Metro Vancouver we make decisions that impact the 2.7 million residents that live in our region. Metro Vancouver engages municipalities, businesses and the general public whenever we are working on a new program, policy, or project across our service areas.

January 2019 Open House

Metro Vancouver held an open house for the Second Narrows Water Supply Tunnel Project in January 2019.

Below is a high-level summary of what we heard:

• Interest in construction schedule and restoration plan
• Maintain lane access for residents
• Minimize construction impacts on residents and park users
• Minimize construction impacts on the ecology of the park
• Questions about slope stability, noise and vibration

Where possible we will incorporate your input into our project plans and we will report back on how we are using that input as this project progresses.
