Chapter 1 – Plan Overview Overview of this Plan and its Development This Multi ‐ Hazard Mitigation Plan is the result of analyses, professional cooperation and collaboration, assessments of hazard risks and other factors considered with the intent to reduce the potential for hazards to threaten people, structures, infrastructure, and unique ecosystems in Latah County, Idaho. The planning team responsible for implementing this project was led by Latah County Disaster Services. Agencies and organizations that participated in the planning process included: • Bovill Rural Fire District • City of Bovill • City of Deary • City of Genesee • City of Juliaetta • City of Kendrick • City of Moscow • City of Onaway • City of Potlatch • City of Troy • Clearwater Resource Conservation and Development Council, Inc. • Deary Rural Fire District • Genesee City & Rural Fire Department • Idaho Bureau of Homeland Security • Idaho Department of Lands • Juliaetta Volunteer Fire Department • Kendrick Volunteer Fire Department • Latah County Commissioners and County Departments • Latah County Highway Districts • Moscow Volunteer Fire Department and Rural Fire District • Northwest Management, Inc. • Potlatch Rural Fire District • Troy Rural Fire District • USDA Forest Service • USDI Bureau of Land Management In the fall of 2009, Latah County Disaster Services solicited competitive bids from companies to provide the service of leading the assessment, developing the data, and updating the Latah County Multi ‐ Hazard Mitigation Plan. Northwest Management, Inc. (NMI) was selected to provide this service to the County. The Project Co‐Managers from Northwest Management, Inc. were Mr. Vaiden Bloch and Mrs. Tera R. King. 7
Phase I Hazard Assessment The Multi ‐ Hazard Mitigation Plan is developed in accordance with the Federal Emergency Management Agency’s (FEMA) and Idaho Bureau of Homeland Security requirements for a county level pre‐disaster mitigation plan. Based on the hazards included in the 2005 document and funding availability, the planning committee in Latah County updated or developed annexes for the following hazards: Updated Hazards: Flood Landslide Severe Weather Wildland Fire New Hazards Assessed: Terrorism/Civil Unrest Extended Power Outage Additional hazard annexes may be added to this Plan as funding allows. The highest priority hazards to be considered for future evaluation are: Hazardous Materials Crop Loss Earthquake Volcano Technological Hazards Pandemic A Phase I Assessment was facilitated with Latah County planning committee to determine the relative frequency of a hazard’s occurrence and the potential impact a hazard event will have on people, property, infrastructure, and the economy based on local knowledge of past occurrences. A matrix system with hazard magnitude on the x axis and frequency on the y axis was used to score each hazard. Magnitude of Hazards Value Reconstruction Assistance From Geography (Area) Affected 1 Family Parcel 2 City 2 County 4 State Block or Group of Parcels Section or Numerous Parcels Multiple Sections 8 Federal Countywide Expected Bodily Harm Little to No Injury / No Death Multiple Injuries with Little to No Medical Care / No Death Major Medical Care Required / Minimal Death Major Injuries / Requires Help from Outside County / A Few Deaths Massive Casualties / Catastrophic Loss Estimate Range Population Sheltering Required Warning Lead Times $1000s No Sheltering Months $10,000s Little Sheltering Weeks $100,000s $1,000,000s $10,000,000s Sheltering Required Neighboring Counties Help Long Term Sheltering Effort Relocation Required Days Hours Minutes A scoring system (shown above) was also used to categorize the relative magnitude each hazard may have on the community. Frequency was rated as “High” for hazards occurring multiple times per year in a 5 year 8
