While geologists have yet to determine a cause for the landslide, one man said he thinks recent rain and a poor drainage system may have had a part.
"The pipes that had been carrying the water just don't work, so the water from the rain had nowhere to go but to soak into the earth," said resident Dennis Baldridge.
The neighborhood, which is above the Shorecliffs Golf Course, was built in the 1960s.
Geologists say the slide opened a 25 to 50-foot vertical drop onto the golf course below the homes. They are still studying the slide.
