Flooding, Sewer & Water Leak Issues

My apartment located in 2240 Lombard, SF. This morning, we notice the sewer in sidewalk back flow with dirty water and back to my building, whole parking is flood . I called my plumber and the to clear the drain & the sewer drain in the sidewalk. The plumber mentioned it is the main sewer outside blocked so back flow to our building. We should call the city even he clear it for me this time.( Actually, it happened serval times a year like that). Hope you do something avoid it happen again.
