To encourage local communities to undertake more pre-disaster mitigation planning, Congress passed the Disaster Mitigation Act of 2000 (DMA2K). This legislation requires all city, county and state jurisdictions to prepare a Natural Hazard Mitigation Plan identifies and ranks the potential local natural hazards, creating a plan to mitigate the hazards and implementing a plan to reduce the impacts of natural disasters. The cities of Rancho Palos Verdes and Rolling Hills Estates have worked together to prepare the Joint Natural Hazards Mitigation Plan, which received approval from the Federal Emergency Management Agency (FEMA) in April 2005. The mitigation plan provides a list of activities that may assist the cities in reducing risk and preventing loss from future natural hazard events. The action items address multi-hazard issues, as well as activities for earthquake, wildfire, earth movement (landslide and debris flow) and tsunami.
