An overnight landslide damaged the backyard of a home and other properties below and hillside Wednesday in Sherman Oaks.

Firefighters responded at about 3 a.m. to the neighborhood in the 3000 block of North Ventura Canyon Avenue, where part of a hillside gave way and started sliding toward at least three homes.

Video from NewsChopper4 showed part of a hillside that gave way behind a home perched above several other residences. The slide left a gap between two sections of pavement around the home's backyard pool and next to a tennis court.

Firefighters said it's not clear what triggered the slide. Late winter rainfall left hillsides around Southern California saturated and prone to slides.
