IFHMP 2017

The IFHMP consists of the following four parts:

Flood Mitigation Gap Analysis

This first step was designed to summarize the existing information surrounding Squamish’s:

  • Hydrology,
  • Geohazards,
  • Potential climate change,
  • Future coastal water levels,
  • Extent and condition of existing flood protection, and
  • Existing policy tools that manage flood hazards.

Through the combined use of updated river models, knowledge of local hazards and mitigation measures, and incorporation of provincial guidance documents, a gap analysis of the District of Squamish’s current flood mitigation program was provided. 

Work is summarized in the IFHMP background report.

Coastal Flood Hazard Mitigation Strategy

Several coastal flood defense options were developed and presented at the first Open House in October 2014. In order to solicit public input on the options and associated risks and consequences, potential mitigation measures were presented and public feedback received at a Public Open House.

The final Coastal Flood Protection Strategy (large file) was adopted by Council on September 29, 2015. 

River Flood Mitigation Strategy

New floodplain mapping has been prepared along with consequence assessments in order to guide preparation of a river flood mitigation strategy. The final draft report is available. Click here to view (large file).

Integrated Flood Hazard Management Plan

The final phase of the IFHMP involved the preparation of the Integrated Flood Hazard Management Plan, which recommends both structural flood protection (i.e dike) improvements and policy solutions. The final draft IFHMP was presented to District Council in the fall of 2017 and adopted October 2017.
