Greening shorelines to Enhance Resilience: An Evaluation of Approaches for Adaptation to Sea Level Rise

2014 – SNC Lavalin for the Stewardship Centre for British Columbia

This report explores use of soft shore armouring approaches as an alternative to, or adaptation of, hard armouring of the shoreline, within the context of climate change, sea level rise practices and guidelines, and flood protection.

The study evaluated the effectiveness of the three soft shore armouring approaches, based on specific scenarios and case examples (communities along the BC shoreline). Each was evaluated according to the following criteria:

  • Adaptability to sea level rise from climate change
  • Effectiveness in protecting the shoreline against flooding
  • Effectiveness in providing ecological resilience
  • Relative cost, taking into account initial capital investment, maintenance and replacement costs.

The report was prepared by SNC Lavalin for the Stewardship Centre for British Columbia, with the support of Natural Resources Canada.
