In just a few days we have a lake out the back. Somewhere under there is a sidewalk. The lake extends almost all the way to the parking lot on the left.
This is what our covered parking looks like in the spring! The water in the mains underneath freezes and the melt from the roof backs up and floods it. This was after the company had come and steamed the pipes to get them flowing again and our maintenance guy had spread de-icer all over. You couldn't pay me to park under there.
