Where I used to live, a little north of Glasgow but a little south of Stirling, there was a big flat bit of low-lying ground where a modern housing estate was built, with a nice little stream at the bottom.

The ground was flat because it was the bottom of a loch drained in the 1500s, by a culvert to a river a few miles away.

All the rubbish that people threw from their cars washed down the stream, into the wetlands that it flowed through, and eventually began to gunk up the culvert. The wetlands got bigger, the stream got deeper, and by the 1970s the housing scheme had a nice little pond instead of a stream, and cracks in every foundation.

It's not as bad as the proposed housing scheme further along the valley, where I have a photo (which I can't find just at the moment, sorry) of the developer's 4m tall sign boards just barely sticking out of a pond the size of the entire fenced-off bit.

Don't drain wetlands then build on them, folks. Geology will always win against you.
