The incident was reported about 4:30 a.m. in the 1000 block of Bayside Drive, according to the Newport Beach Police Department.

Dirt and debris covered about 50 feet of Bayside Drive, just east of Jamboree Road.

Bayside was originally expected to be closed between Jamboree and El Paseo Drive until about noon, police said. It was reopened by 1:30 p.m., video from the scene showed.

Officials shut off the water in the area after the main break, but it is unclear how the break occurred.

Crews were working on cleaning up the area, and much of the mud was cleaned by early afternoon.

A man who lives in the neighborhood said he regularly walks in the area and thought that the steep hill was precarious.

"I've always walked by here and thought, 'Man, I wonder if one day that will go,' and the day came," said Mike, who did not want to give his last name. "It's so steep."
