The Cost of Removing Infrastructure in the US

You’ve raised your house up on stilts and your town has added higher seawalls and pumping stations, but sea level rise is relentless. Eventually, you may have to consider the ultimate solution: Leaving your home, giving the land back to nature and starting over somewhere else. There’s a jargony sounding name for this solution: Managed Retreat.

In our season finale, we head to a small island community off the coast of Louisiana that has lost 98% of its land to rising seas and sinking land. Now residents have to decide if they’re ready to leave the place most have called home their whole lives, or be swallowed up with it. Later in the episode, we unpack what managed retreat might mean for the rest of us, even those of us who don’t think we’re at any risk.
