Why is water streaming down my driveway after heavy rain?

Heavy rain can cause water to stream down a driveway, leading people to suspect a leak even though shutting off the main water and sprinkler lines does not stop the flow. Without knowing the source, homeowners are left unable to troubleshoot the problem or figure out how to fix related water damage by the door.
