Water started bubbling out of the main cover onto Carolina Street near Mariposa. Nearby yoga studio owner Renee Sera says she was about to begin a class when water started flooding her studio, "The carpet is wet, there's a little slope so the water is coming in, and I'm out of towels so the water is just seeping down, spreading through my carpet. I'm sure the city will be happy compensate me for that."
Crews with San Francisco Public Works quickly responded to the scene. No word on what caused the water main break.
