<br /> <br />2021 Multijurisdictional Local Hazard Mitigation Plan <br /> <br />Type of Event Disaster Declaration # Date <br />Wildfires DR-65 December 29, 1956 <br />Flooding DR-47 December 23, 1955 <br />Flooding DR-15 February 5, 1954 <br /> <br />Review of these events helps identify hazards of concern and targets for risk reduction activities. However, many <br />natural hazard events do not trigger federal disaster declaration protocol but have significant impacts on their <br />communities. These events are also important to consider in identifying hazards of concern and establishing their <br />recurrence intervals. Individual jurisdictional annexes in Volume 2 list the events that affected each planning <br />partner. <br /> <br />5.2 IDENTIFIED HAZARDS OF CONCERN <br />The Steering Committee considered the full range of natural hazards that could affect the planning area and then <br />selected those that present the greatest concern for risk assessment in this plan. The process incorporated a review <br />of state and local hazard planning documents as well as information on the frequency of, magnitude of, and costs <br />associated with hazards that have struck the planning area or could do so. Anecdotal information regarding natural <br />hazards and the perceived vulnerability of the planning area’s assets to them was also used. Based on the review, <br />this plan addresses the following hazards of concern (presented in alphabetical order; the order of listing does not <br />indicate the hazards’ relative severity): <br /> Climate change <br /> Dam failure <br /> Drought <br /> Earthquake <br /> Flood <br /> Landslide/mass movements <br /> Sea-level rise <br /> Severe weather <br /> Tsunami <br /> Wildfire <br /> <br />Additionally, other “hazards of interest” are qualitatively profiled but not fully assessed. The Steering Committee <br />determined that these other hazards, though not required to be evaluated under federal guidelines for hazard <br />mitigation plans, are important to recognize qualitatively in this plan. Profiles, without quantitative risk <br />assessments, are provided for the following hazards: <br /> Public health and pandemic <br /> Terrorism <br /> Cyber threats <br /> Communication failure <br /> Hazardous materials release <br /> Pipeline and tank failure <br /> Aircraft incidents. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />5-2
