Shoreline Mapping

Over the course of the Resilient Coast for Salmon initiative, the team will coordinate mapping the entire East Coast of Vancouver Island.

The extent of coastal hard armouring (like seawalls) is currently a data gap, but would provide valuable information to prioritize community actions to better adapt to sea level rise. So we embarked on our journey to map the entire east coast of Vancouver Island — some areas by foot with local citizen scientists and others by boat.

The priority is to collect information on the extent of local shoreline hardening to be compiled with high-resolution topographical shoreline data and imagery and other local nearshore and estuary habitat layers into the Strait of Georgia Data Centre's new Marine Reference Guide.

Once the data are complied, summary reports will be created for each community of focus, and these will be made available on our website. We will also host community meetings to share our findings on the extent of hard armouring and discuss the implications. Along with the results from boat monitoring, we will share key imagery, maps, and provide an opportunity to discuss hypothetical options for adaptation and restoration, and finish with a live Q&A session.

There are a number of expected benefits from this effort, namely:

• It will greatly increase the information base on extent of shoreline hardening;
• It will highlight areas that should be prioritized for soft shores approaches and allow advanced planning for mitigation or avoidance of future climate change impacts such as sea level rise;
• Engaging and creating citizen science teams on East Coast Vancouver Island for mapping will lead to increased understanding of soft shores and nature-based concepts and the need for the approach, leading to more effective buy-in for nature-based solutions in local communities.
