For the fourth time in two years, parts of New South Wales are flooding. And once again, people are asking why so many houses were allowed to be built on flood-prone areas.
As Brian Cook and Tim Werner write, developers have strong financial incentives to build on cheaper flood-prone land. Home buyers are drawn to live by the water, and may overlook flood risk in exchange for cheaper housing. And perversely, flood mitigation efforts can make people feel secure when in fact, engineering solutions ward off smaller floods but can do nothing to stop the big ones.
What’s the solution?
A key first step: harden the boundaries of flood-prone areas. If authorities have the appetite, a big step would be to make developers retain liability for floods. That could make many think twice about encroaching on floodplains.
