City of Santa Ana Emergency Operations Plan Part I Basic Plan 2.3 Hazard Analysis Process and Ranldngs Hazard analysis provides information on the hazards that are reasonably likely to occur in or affect the City of Santa Ana; an assessment of the risk to life, property and the environment that may result from the hazard event; and potential locations within or around the City that may be susceptible to the event. Hazard analysis is dependent on the availability of data for each hazard. Analysis is based on the record of historical events as well as future projections, and data is drawn from such disciplines as geography and geology, climate and weather, population and demographics, infrastructure and development, and homeland security. Gathering data for hazard analysis requires a commitment of resources from multiple City departments and relevant outside agencies. Santa Ana's Hazard Analysis is prepared through discussion among representatives from emergency management, police, fire, public works and engineering, planning and development services, City administration and outside resources. Santa Ana's hazard analysis consists of a three -step process: 1. List all natural, technological or human -caused hazards that may reasonable, foreseeably harm the City. 2. Score each identified hazard on the following criteria and points: o Frequency of Occurrence • Rare or Unlikely 1 • Occasional 2 • Common o Geographic Extent • One or Few Locations • Citywide Impact • County/State/NafronalImpacts o Harm to Persons (Injuries or Deaths) • Little or No Physical Injury • EMS/Hospitals/Coroners Strained • EMS/Hospitals/Coroners Overwhelmed o Damage to Property or Infrastructure • Little or No Physical Damage • Hours or Days of Cleanup or Repairs • Weeks or Months of Cleanup or Repairs o Warning Time Received • Days or Hours • Minutes • None 3. Total the points scored for each hazard, resulting in a numerical ranking of all hazards. This numerical ranking is not a mathematical certainty, but instead is a guide for prioritizing planning efforts, preparedness resources and community education. This hazard analysis indicates that the City is at risk from a variety of natural, technological and human -caused hazards, with the potential to cause disasters exceeding any one jurisdiction's capabilities to successfully respond and manage the event, making coordinated command and control and the support of outside resources essential. The current Hazard Analysis ranking for the City of Santa Ana appears below: 31
