It’s not my field of expertise but not much I’d imagine - floodplains are usually low lying flat areas that flood waters will settle in anyways given expected rainfall patterns, and/or due to their proximity to rivers, levees, lakes and dams. You’d dismantle whatever infrastructure was in-place (irrigation systems, filtration, the club house) and let it re-wild.
What would be involved in converting them back into flood plains?
