The future already exists, you just have to look for it.
Did you ever notice, as a kid, that it rained so much that the streets of your neighborhood almost literally was filled with water? You practically had to walk in a street-long puddle that tended to reach your ankles. And didn’t that make you wonder if the drainage holes in your neighborhood were broken? As a kid, I wondered why they didn’t drain the water out of the streets faster than it did.
But there is a purpose for this!
Water used to drain out really quickly, and it would be deposited to a near stream or pond. The problem was, in a lot of cases this would stop flooding in your area, only to cause flooding where the drainage led. We were moving the problem some place else, not fixing it.
So, engineers changed the drainage to where it would only drain water at a slower rate; this way, both areas would be relatively okay. Now there is a lesser chance of flooding!
If your drainage doesn’t seem to be working at all - it might be clogged with leaves and other things that get washed up into it, and you may need to have that fixed.
