Managed Retreat from Floodzones & Coast management policies in US
September 11, 2019 2:06 PM   Subscribe

We are looking for examples of buy-outs, and related Coast management policies e.g. disallowing new building in 100 year floodzones, disallowing modifications or reconstruction in 100 year floodzones, buyouts, infrastructure maintenance. Land converted to use as parkland, etc

Google "non-structural flood control" and limit the search to, and you'll get loads of info about the non-structural flood control programs overseen by the Corps of Engineers.

Oakwood Beach (and Ocean Breeze) in Staten Island were subject to buyouts after Hurricane Sandy. To the best of my knowledge most of the affected areas are basically being returned to "nature."

From Metafilter's Own™ adamg: Why the Charles doesn't seem to flood as much as other rivers. Posted after a huge rainstorm, IIRC.

Harris County TX has a home buyout program that buys flooded properties and then turns them into open land. I have seen previously flood neighborhoods that have had most of their homes removed under this program.

Again re the NY coastal sites. There's a book called Rising, I did a fanfare on it and have a lot of notes, will post exact page numbers Saturday when I have time. The book has extensive notes on research routes and dead-ends.

Also I heard a rumour five years ago that China was forbidding new development below 10 metres above high tide, but I've never been able to confirm.

Here's a youtube video of a presentation at some conference by the floodplain programs manager for the Illinois DNR about Illinois floodplain management. Warning - this guy makes jokes that may not be Metafilter friendly.

The Isle de Jean Charles situation in Louisiana is a forced migration, if that fits your needs.

Austin Texas is far from the coast but does have flooding problems. The city has been buying a neighborhood and destroying the houses in a particularly bad area.

Canada, so not an answer to your question, but an interesting comparison for the difference in political possibility overlaid on pretty similar economic and engineering cases: Canada Tries a Forceful Message for Flood Victims
