Back before 1980, businesses could and often would have DIRT parking lots. Not now. Everything is paved. All the rainwater runnoff goes into storm drains.

At least in my town this is no longer true. Developers must build retention basins to offset roofs, driveways, sidewalks, etc. Flow from the basins is to be limited to the rate of runoff that would exist if the paving hadn't been done. One shopping mall west of town has a huge retention basin next to the parking lot. I'm on the storm water board (a volunteer board) so I manage to keep up on these details.
