“Cape Shoalwater, Washington is the fastest eroding stretch of land on the west coast, maybe even the entire Western Hemisphere.” —Eddie Jarvis.

Excerpts;

There’s a reason a quiet and desolate strip of sand here is nicknamed Washaway Beach. Coastal erosion has claimed an average of 100 feet of this shoreline every year for the last century, according to Washington’s Department of Ecology.

That makes North Cove the fastest-eroding place on the West Coast…

A softer approach, living shorelines as an alternative to a hardened coast; PortCity (05-12-2018)

“Living Shorelines” Will Get Fast Track to Combat Sea Level Rise; Scientific American (07-06-2016)
As sea levels rise along U.S. coasts, it may soon get easier for people and local governments to obtain federal permits to build what are known as “living shorelines,” natural or nature-based structures designed to protect communities and infrastructure from extreme storms and flooding even as they protect habitat.

Let’s end war with ocean, Op-Ed by Orrin H. Pilkey (04-2017)
The immediate future most certainly holds more miles of sandbags, resulting in more narrowed and ugly beaches.But this trend can be halted and reversed. Now is the time to make peace with the ocean.The time is now to stop sandbagging, both physically with no more shore-hardening structures, and politically with no more exceptions to the intent of the rules, no more undermining existing legislation, and a return to enforcement…

The only answer to rising seas is to retreat; By Orrin H. Pilkey & Keith C. Pilkey; The News & Observer (10-18-2017)
Except for the timing, there is no controversy among scientists regarding sea level rise. Defending the coast and holding the shoreline in place ultimately will be futile. With a three-foot or a six-foot sea level rise, we will retreat, probably beginning within the next 50 years…

Portugal to demolish buildings threatened by coastal erosion

Excerpts;

The Portuguese Environment Agency’s new coastal plan involves demolishing dozens of buildings and houses along a 122 kilometre strip of coastline between the city of Caminha and Espinho, deemed at severe risk from coastal erosion aggravated by climate change.

In the next ten years Portugal plans to spend almost 470 million euros to try to reduce the risks to it population from coastal erosion and its vulnerability to climate change…
