More than a half inch of rain fell in less than 20 minutes Monday, causing mud to flow into the houses in Manitou Springs and western Colorado Springs.
A witness said the slide pushed her car about five feet and left the engine compartment filled with sticks, twigs and mud.
While the rainfall was intense, the storm moved quickly through the area. A meteorologist says the damage would have been much worse if the storm had settled over the area.
Colorado Springs officials say more than 160 people were relocated from a low-lying trailer park as a precaution.
