Default rule and exceptions
The California Department of Insurance says homeowner policies generally exclude damage from mudflow, mudslide, debris flow and landslide, and that landslide damage is not covered under the National Flood Insurance Program. If others' actions or negligence caused the event, the department points to an attorney. LA County Public Works says maintenance of its hillside slope and bench drains is, with few exceptions, the homeowner's responsibility.
