Louisiana Unveils Ambitious Plan to Help People Get Out of the Way of Climate Change

Below excerpts are from a May 15th article in Bloomberg. The full article is available here.

The state [of Louisiana] on Wednesday issued a sweeping blueprint—the first of its kind in the U.S.—for managing the ongoing population movement away from its coastal areas, and preparing inland communities to receive an infusion of people.

Officials around the country are being forced to confront whether, and how, to help people get out of the way of the effects of climate change. None has gone so far as what Louisiana is proposing.

The document calls for high-risk areas to “transition away from permanent residential development.” For those residents and structures that remain, the report urges local officials to impose stronger building codes and stormwater management systems.

D.C. Is First to Plan to Remove, Retrofit Flood-Prone Buildings

According to Bloomberg, Washington D.C. is announcing a goal of retrofitting or removing all of its flood-prone buildings by 2050, the first major U.S. city to set such a policy.

“In some cases, we’re going to have to figure out how to do managed retreat and relocation,” said Kevin Bush, Washington’s chief resilience officer and the lead author of the strategy.

The Congressional Budget Office recently projected that hurricanes and storms will consume 0.3 percent of the nation’s GDP, while bond rating companies warn that ignoring extreme weather will hurt cities’ credit ratings.

The same may be true for towns, like Southampton.

The Problem with Beach Nourishment

Below excerpts are borrowed courtesy of a December 10th article and video published by Vox. The full article is available here.

About 80 to 90 percent of sandy beaches along America’s coastlines are eroding. This is a problem because the developments humans build near them are static. So as beaches shrink, coastal hazards can threaten to damage or destroy homes and businesses while negatively impacting tourism that depends on the beach.

The most popular strategy to counter these risks is a process called beach nourishment. Coastal engineers will add new sand to an eroding beach in order to rebuild or expand the shoreline.

But researchers discovered that coastal defense schemes like beach nourishment may ultimately do more harm than good by providing a false sense of security in critically eroding areas. There is evidence that beach nourishment can “mask or reduce the apparent impact of coastal hazards without changing the natural processes driving them.”
