Financing landslide hazard mitigation in the United States

Landslides continue to be an expensive problem in the United States. This paper explores the difficult problem of how to pay for reducing existing landslide risks. The paper examines a hierarchy of methods to cover repair and long term maintenance of unstable areas: assessment districts; homeowner associations; and insurance. It looks at several examples, and finds that costs in all but the worst cases average about $5000 to $15 000 per property. Landslide insurance is shown to be feasible and could be designed so as to encourage mitigation. The paper concludes that an optimal approach for mitigation and compensation would combine insurance with assessment districts.
