Erosion on Rocky Shores | Shore Friendly

THE BASICS

Puget Sound properties with rocky shorelines—such as many in the San Juan Islands—typically have low erosion rates. They are also less likely to be modified because the rocks provide natural shoreline protection. Still, it’s wise to follow proven management practices that reduce erosion and help maintain healthy habitat.

WHAT SHOULD I DO?

Make sure rainwater and roof runoff are diverted away from the waterfront, leave native trees and vegetation intact, and build stairs and trails in a way that allows for natural erosion but doesn’t aggravate it.

WHAT ABOUT CLIMATE CHANGE?

Rising sea levels due to climate change are a legitimate concern for waterfront homeowners. Current estimates of sea-level rise over the next century range from less than a foot to more than three feet. Rocky shorelines are less vulnerable than sandy beaches and bluffs, but they may also benefit from soft shore protection, which can mitigate the effects of sea-level rise without harming native species
