Hurricane Idalia shows nature may provide the best shoreline protection – NPR

When Hurricane Idalia slammed into Florida’s Gulf Coast in August (2023), one of the hardest hit areas was Cedar Key. A nearly 7-foot storm surge battered the small fishing community…(NOAA) says Idalia caused an estimated $3.6 billion in damage…But on Cedar Key, when the water receded, scientists found some good news amid all the damage. Nature-based “living shoreline” projects built to protect roads, buildings and other structures were relatively undamaged…

In mid-November 2021, a great storm begins brewing in the central Pacific Ocean north of Hawai‘i. Especially warm water, heated by the sun, steams off the sea surface and funnels into the sky.

A tendril of this floating moisture sweeps eastward across the ocean. It rides the winds for a day until it reaches the coasts of British Columbia and Washington State. There, the storm hits air turbulence, which pushes it into position—straight over British Columbia’s Fraser River valley….

Last September, the U.S. Army Corps of Engineers unveiled its proposal to protect the greater New York and New Jersey metro area from the next catastrophic flood. It is an epic plan that includes dozens of miles of floodwalls, levees and berms along the shoreline and 12 storm surge barriers — arrays of movable gates — across entrances to waterways throughout the region.

The plan is estimated to cost a staggering $52.6 billion. It’s by far the most expensive project ever proposed by the Corps.

The trouble is that despite its great ambitions, the Corps’s plan demonstrates the shortcomings of relying on massive shoreline structures for flood protection…
