Canadian Coast Guard Seymour Narrows Radar Site and Power Line

The Canadian Coast Guard is undertaking a project to construct a new Radar and Communications Site and new powerline at Seymour Narrows. The site is located along the west coast of BC near Campbell River at a high elevation to enhance range to radar signals. The purpose of developing this new radar site includes but not limited to:

  • Enhance marine situational awareness for the Coast Guard and other federal partners such as National Defence and Port Authorities;
  • Address immediate gaps in radar coverage on Canada's Westcoast in support of marine safety activities;
  • Enhance the Coast Guard's ability to identify vessels and to improve the common operating picture in the area;
  • Provide support to Transport Canada in enforcing the moratorium on tanker traffic on British Columbia's north coast; and
  • Provide a back-up solution for Marine Communication Traffic Services centers in the event of the loss of digital signals from vessels navigating in Canadian waters.

In general, project works that have not already been completed are proposed to start in September 2020 and end in November 2021. Clearing activities for the radar site, road and powerline were completed in 2018 and 2019.

The scope of the project is to build an approximately 150ft (46m) radar tower, 16ftx33ft (5mx10m) equipment building, 1km powerline to Browns Bay, 300m access road, and a helicopter landing pad. The proposed implementation of the site development is as follows:

  • Summer 2018 – Preliminary Site Investigations:
    • Clearing a temporary 75ftx75ft (23mx23m) helicopter landing area
    • Site survey
    • Site layout drawing
    • Environmental Assessment
  • Summer 2019 – Design Development:
    • Site clearing
    • Powerline clearing
    • Road Construction
    • Detailed survey
    • Design drawings for building, tower, and helipad.
  • Summer 2020 – Winter 2021 – Construction Activities
    • Tower, building, powerline, and helipad installation

Environmental Assessments were completed in the project areas in 2018 before the Impact Assessment Act was implemented in August of 2019. With the addition of plans to install a powerline to the site after August of 2019 this triggered the Impact Assessment Act no longer allowing the project to be grandfathered in to the 2012 Canadian Environmental Assessment Act.
