The City of Courtenay is using the "Green Shores" method to repair shoreline erosion.
In 2016, two locations in south Courtenay will see repairs and site restoration:
- Riverway Walkway near 29th Street
- Sandpiper Drive
With this technique, beach slopes are re-contoured to a more stable slope, and larger logs are embedded half-way into beach substrates and connected to an underground anchor system using wire rope and ballast boulders. These logs help reduce wave energy and retain sediments as waves recede. The retained sediment provides opportunities for vegetation to establish and can provide spawning habitat for forage fish.
The Green Shores technique is also designed to mitigate wave energy, protect or enhance ecological function, and avoid causing erosion on neighbouring properties.
General goals for preserving and protecting natural shorelines are identified in the City of Courtenay’s Official Community Plan [PDF - 1012 KB] including as a Development Permit condition and as a ‘design with nature’ climate action adaptation strategy.
