Rain storm in SF

I was headed to a client meeting today when a storm of biblical proportions broke out. That would have been one thing, but I've never seen anything quite like this where water was literally erupting upwards. It was so odd that I had to stop and film it and I wasn't alone; a network cameraman was doing the same. So, can anyone explain to me the law of physics that caused this to occur?

Do you think it was the people who live underground got carried away.

Like hydraulic equipment: little pressure over large area (rain going into big drains w/ big pipes) makes lots of pressure over little area (little drains w/ little pipes) when system is closed (pipes that drain other pipes overloaded.)
