It means they have really settled in and become part of the landscape. It drives home to me, too, how stable your weather is, and your watershed, too. Here, choosing the right size culvert can be guesswork, and the engineering approach is "fix on failure". As our land gets developed, the runoff goes up, and little culverts like that just get washed out, or clogged with debris and then washed out.

Much land was developed here four to five centuries ago, so that gives some stability, and water has been managed here for very long as well. The Dutch can't seem to look at any body of water without thinking about managing it 8-). The whole system combined can take many times the average amount of water and get it to the nearest river.
haha -- I just have to laugh. Some of the best river forecasting software comes out of the Netherlands, too! That's a long time to have stability in land development! But it takes climate stability, too. Other parts of Europe have seen some tough flooding of areas that haven't flooded for centuries, though, with some extreme storms over the last few years. Keep those culverts clear! : )
