Water is coming from underneath the asphalt and concrete of the street along Froude near Narragansett Avenue. And a number of local agencies have responded to what is reported to be a water main break.
But is it also a sinkhole? A city of San Diego spokesperson said they had a report of a sinkhole.

Having dealt with quite a few of these breaks in my time, I can say that the damage caused by a broken main can be extensive. I remember a case in San Marcos or Vista where a contractor broke a large main in a major intersection. Before they could shut it off, it destroyed the intersection and the company went bankrupt because of it. Concrete streets can be completely undermined and still stand up for a period of time. I would guess they will find a big cavity under the pavement when they open it up. I remember another case in a Pacific Beach alley where a contractor was to place a sewer main. They saw-cut the concrete and as soon as they removed some of the saw-cut material, the entire alley collapsed. The contractor said the voids below the concrete were so big a VW Bug could have fit under there.
