  • What is the Eagle Viewing Area / Siyích'em Reserve Dike Master Plan?

    This project assesses options for upgrading the dike protecting Brackendale and the rest of Squamish in accordance with the recently completed Squamish Integrated Flood Hazard Management Plan (IFHMP). The project also considers non-flood protection challenges and opportunities of the area. 

    The project will consider possible dike alignments and other flood protection options for the area.  The aim is to develop a plan which accommodates a number of considerations, including:

    • shared jurisdiction between the District and Nation;
    • infrastructure on, through, and next to the dike;
    • encroaching development;
    • private property challenges;
    • impinging river flows and debris impact;
    • sensitive environmental habitat areas; and
    • tourism and recreational use.


    This project does not involve implementation, i.e. no dike construction. A future project or projects will implement the plan and will provide further opportunities for input.

  • Why is a dike upgrade needed in this area?

    The Integrated Flood Hazard Management Plan found that the existing dike along this reach is deficient in the following ways:

    • a history of seepage and piping issues;
    • non-standard dike cross-sections;
    • unknown subsurface conditions;
    • inadequate dike height;
    • vegetation impacts to dike; and
    • uncertain seismic performance.

  • Why is the Master Plan being developed for this section now?

    This section of the Squamish River Dike is particularly vulnerable as the river takes an abrupt turn at the upstream end and due to the deficiencies discussed above. Additionally, there are a number of considerations to take into account based on the varied uses of the area, and therefore an early planning process involving stakeholder input is necessary before detailed design and construction.

  • When will the dike upgrades be built?

    When the upgrades will be built depends on the option selected for flood protection, funding, and other District and Nation priorities.  Prior to construction, there will be additional opportunities for stakeholder input.

  • How will the project proceed and what is the schedule?

    The project involves the following major phases of work and timelines:

    Phase A: Initiation, information gathering, and context; Summer 2019
    Phase B: Visioning, brainstorming, and shortlisting options; Fall 2019
    Phase C: Conceptual design/engagement on shortlisted options;    Fall 2019 - Winter 2020
    Phase D: Structured options evaluation and selection; Winter 2020
    Phase E: Draft master plan; and Spring 2020
    Phase F: Final engagement and final master plan. Spring 2020
  • How and when can I participate?

    Stakeholder participation is important to the success of the project, and input is sought at the following milestones:

    • Values and concerns related to the site;
    • Review of options shortlisted by the District and Nation; and
    • Review of the draft master plan.


    The engagement process includes the following formats/venues:

    • Online survey on values and concerns related to the site (click here to open);
    • Public open house and online survey to gather feedback on shortlisted options (Fall 2019);
    • Targeted stakeholder workshops to gather feedback on shortlisted options (Fall 2019);
    • Public open house and online survey to gather feedback on the draft master plan (Spring 2020); and
    • Targeted stakeholder workshops to gather feedback on the draft master plan (Spring 2020).
  • Who can I contact about this project?
