The qathet Regional District successfully secured provincial grant funding through the UBCM Community Emergency Preparedness Fund to complete a Regional Coastal Flood Adaptation Strategy (RCFAS).
As climate change occurs, many coastal communities are recognizing and planning for the impacts from increasing flood and erosion risk due to sea level rise and coastal storms. Building on previous flood mapping along our coastlines, the qathet Regional District, Tla’amin Nation, and the City of Powell River are now working together through development of the RCFAS.
This spring, we will be hosting online community information sessions and in-person public workshops to engage with local residents about the impacts of climate change along our shoreline and what can be done to adapt and build resilience. Feedback gathered between now and June 2022 will inform the development of the RCFAS later this fall.

Thank you to everyone who participated, please click the link below to view preliminary results from the online survey.
An in-person public workshop was held on June 22, 2022 at the Willingdon Beach Park Pavilion. During the workshop we shared project background information, and sought feedback on making wise decisions together and adaptation options. Thanks to all who attended on this beautiful day.

Through this work, we will explore how sea level rise and a range of coastal storms (both small and frequent, as well as large and rare) interact with the places and things that communities value along the coast.
Put simply, sea level rise is caused by expanding ocean water as it warms and increased melting from ice sheets and glaciers. As ocean water rises, coastal communities are more likely to experience flooding than in the past. This is especially the case when sea level rise combines with high tide as well as coastal storms (i.e. storm surge, and wind and wave effects).
More frequent coastal storms and rising sea levels can also increase coastal erosion, which acts to remove sediment and rock from the shoreline.
Of course these changes don’t happen on their own: they combine with other factors such as land use, economic activity, ecosystem health, cultural values and our ability to adapt and change, to determine where and how vulnerable our coastlines are to coastal flooding and erosion. This tells us the level of risk we face in particular locations, and informs which adaptation actions we might want to prioritize.
Note: This project focuses on the coastline and does not address flooding or erosion from extreme rain events or along inland streams, rivers or other water bodies.
We have already conducted two initial coastal flood assessments at various scales to understand where and how flooding and erosion may impact our shoreline. Coastal flood mapping and a risk assessment were completed by Tetra Tech Canada Ltd in 2018. That study identified priority areas at risk due to impacts to people, critical infrastructure and the environment.
Since then, more detailed coastal flood mapping has been completed for the prioritized areas on the mainland and island areas in 2021. The more recent mapping considers coastal storms, sea level rise projections through the year 2100, and coastal erosion potential. These assessments will be enhanced and used to inform the engagement efforts this spring and contribute to the development of the RCFAS later this year.
A collaborative approach is at the core of this process. This work involves complex decision-making around how we adapt to and reduce coastal flood and erosion risk. Community engagement is an important value guiding this work to ensure transparency and enhance our collective understanding of risks facing our shoreline and options for addressing them.
