Natural Hazard Mitigation Plan
City of Portland Natural Hazard Mitigation Plan
2010 – Executive Summary
Hazard mitigation planning is a process in which hazards are identified and profiled, people and facilities at risk are assessed for threat and vulnerability then mitigation actions are developed. The result of the process is an integrated and coordinated effort to mitigate hazards. The expected outcome of all actions of the City of Portland 2010 Natural Hazard Mitigation Plan (NHMP) is to lessen the impact of damage caused by natural hazards to life, the economy, infrastructure or our ability to continue to operate as a community and city. The purpose of the 2010 NHMP is to document these actions and determine priorities and implementation efforts.
In response to Federal Emergency Management Agency (FEMA) Disaster Mitigation Act of 2000 (DMA2000) requirements, Portland submitted their first Natural Hazard Mitigation Plan in 2005. The DMA2000 required every state, county and city receiving federal mitigation funds to have a NHMP. FEMA guidelines for developing plans were established in September of 2002 and Portland’s process began in early 2004.
The 2010 update to the 2005 NHMP, identifies eight natural hazards and 102 action items. The hazard analysis used in the 2005 plan was last updated in 2006 and will be updated again in 2011 by Portland Office of Emergency Management. The natural hazards that this plan will address over the next five years are (listed in order of impact and then frequency of occurrence):
- Earthquake
- Severe weather
- Flood
- Landslide
- Erosion
- Wildland urban interface fire
- Invasive plant species
- Volcanic activity
