About 150 residents in the North Beach district were evacuated from several buildings Tuesday morning after a landslide partly buried an apartment building and a strip club in a shower of dirt and boulders.

The hillside collapsed a little after 3 a.m., closing a main thoroughfare through the city for several hours but causing no injuries, authorities said.

At least four buildings were evacuated after the slide, and officials shut off water and electricity to the structures.

City engineers were assessing possible damage as boulders and mud piled several stories high against an apartment building and the club.

"Fortunately, everyone had just left," said Gary Marlin, whose management company oversees the Broadway Showgirls Cabaret at the bottom of the hill. The slide appeared to have caused a water main to break in or near the club, causing serious water damage, he said.

Residents were also forced to leave a 45-unit apartment building perched at the edge of the collapsed hill over concern its foundation had been compromised.

Authorities were trying to determine what caused the slide.

More than a half-inch of rain fell on the city since Monday, according to the National Weather Service. More showers were predicted Tuesday.
