The drenching rains that have fallen on Austin this year have provided sizable benefits: Reservoirs are recovering, lawns are green, and this summer will be cooler as a result. (Maybe a little more humid, too.) But there are, of course, downsides to the rain, most notably the serious damage to lives and property from flooding. Austin’s infrastructure is taking a hit, too, and you don’t have to go far to find it. It’s right underneath you. Yes, we’re talking about potholes. Those holes in the road form thanks to two things: water and traffic, both of which Austin has plenty of lately.
