Golf courses are often built on floodplains, so tbh converting them into protected grassland/wetlands/carbon sinks may be better than building dense housing in flood prone areas. But ofc case by case basis according to topography
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?
