Underdrains.
Included among the many things we never think about are underdrains. As cities become more sophisticated, so do their regulations on development. I suspect that some cities experienced troubles with the concrete curbs and gutters along their roadways — trouble likely caused by the effect of water moving, freezing and thawing, under the curbs. The engineering solution to this is to install tile — underdrains — under the curb. The tile, connected to the storm water inlets, wicks the water away, thereby minimizing future prospects for damage. Bet you never gave them a minute of thought before.
