Sisyphus on the Beach: Dorian Underlines Coastal Cities' Endless Rebuilding Task Reuters JACKSONVILLE BEACH, FLORIDA - Just months after the U.S. Army Corps of Engineers completed a $16 million project to restore sandy beaches in Jacksonville, Florida, Hurricane Dorian is about to pound them again, illustrating the uphill battle that American coastal cities face in protecting their most valuable asset. The hurricane, which has already caused devastation and at least five deaths in the Bahamas, is forecast to cause some erosion at about 80 percent of the sandy beaches between Florida and North Carolina as it curves northward this week, according to the U.S. Geological Survey. That figure is similar to forecasts ahead of other past major hurricanes in the region, and some of that erosion will be temporary: Sand that gets swept offshore in a storm is slowly returned to the beach in the following weeks in gentler weather. But dunes, which are often the last buffer between the ocean and coastal buildings and infrastructure, can take months or years to naturally recover from damage. .
