It’s one, but you aren’t supposed to build that close to the wetland. Like a drain in a house, just because, you should always want water to go somewhere if its on the floor else would have long term problems. Part of the reason street roads are not flat.
The image is the equivalent of choosing to build a house on low tide. and wouldn’t realistically happen.
My country is basically a continuous mountain range. We’ve had massive floodings because of heavy rain due to climate change. It is the floodplains, controlled rivers and wetlands that gets hit the worst

There are cities built on top of former wetlands. And they are fine. Sure, a proper drainage required, and sometimes dam/barrier, but it is doable.
