  1. BLAINE COUNTY MULTI-HAZARD MITIGATION PLAN UPDATE Contractor: Tetra Tech, Inc. Daphne Digrindakis 406-475-2648

  2. WHAT IS MITIGATION? Mitigation is a sustainable action that will reduce or eliminate injury to citizens, damages to structures and allow continuity of critical society function. Types of mitigation projects include: • Property Protection • Structural • Prevention • Emergency Services • Natural Resource Protection • Public Education and Awareness

  3. WHY HAVE A MULTI-HAZARD MITIGATION PLAN? • Required by FEMA in order to receive mitigation funds after a declared disaster (HMGP), Public Assistance (PA) C-G. • $100 million available annually through competitive grants for hazard mitigation projects through: • Hazard Mitigation Assistance grant program (HMGP) • Pre-Disaster Mitigation (PDM) grants program • Flood Mitigation Assistance (FMA) grants program

  4. APROACH FOR2018 MITIGATION PLAN UPDATE • Review each section of the 2012 PDM Plan • Implement planning process for public involvement • (website: www.countypdm.com / password: Chinook) • Review recent plans and studies • Update hazard profiles and identify any new hazards • Update critical facilities • Update risk assessment • Update mitigation goals, objectives & projects • Update capability assessment • Update plan maintenance procedures • Formally adopt plan

  5. 2012 PLAN REVIEW SECTION 1.0 - INTRODUCTION Blaine County first completed a Pre-Disaster Mitigation (PDM) Plan in 2006. This PDM Plan was updated in 2012. Hazard Mitigation Plans must be updated every 5 years to remain eligible for disaster funding. Must be adopted by resolution by County and Cities. New FEMA guidance for completing PDM Plans in 2013. Multi-Hazard Mitigation Plan instead of PDM.

  6. 2012 PLAN REVIEWSECTION 2.0 - PLANNING PROCESS • Project Stakeholders • County and City of Chinook and Harlem staff, response personnel, school districts, medical, local organizations, state, federal, non-profits, businesses • PDM Planning Team • Jurisdictions wishing to adopt plan must participate • Conference calls/planning meetings • Review of Plans and Studies • Public Meetings • Project Website • www.countypdm.com. Password: Chinook • Plan Review

  7. REVIEW OF PLANS & STUDIES • Plans with Mitigation Considerations • County and City Growth Policies • Subdivision Regulations • Zoning Ordinances • Building Codes • Flood Mitigation Plan • Community Wildfire Protection Plan • Analyze Development Trends • Determine what hazards future development projects are exposed to.

  9. 2012 PLAN REVIEWSECTION 4.1 – RISK ASSESSMENT • Natural, Man-Made, and Technological Hazards most likely to cause a disaster in the County. • Hazards that have the potential to cause fatalities/injuries or property damage. • Use Calculated Priority Risk Index (CPRI) to Re-Prioritize Hazards (see handout). • Probability - Highly likely to unlikely • Severity/Magnitude - catastrophic to negligible • Warning Time - < 6 hours to > 24 hours • Duration - < 6 hours to > one week

  11. 2018 MITIGATION PLAN UPDATE HAZARD PROFILES • Identify Additional Hazards to Include in Plan • Communicable Disease, Terrorism, Cyber Security • Profile 8 Hazards in Plan • Organized in Plan by priority • Some hazards can be combined into one profile • Lower priority hazards included in Plan appendix • Each Hazard Profile to Include • Description and History • Vulnerability and Area of Impact • Probability and Magnitude • Future Development • Implications of Climate Change

  12. 2018 MITIGATION PLAN UPDATE RISK ASSESSMENT METHODOLOGY • GIS layers of hazard areas • Some hazards have uniform exposure across county • Analyze buildings at risk from various hazards • Critical facility locations and insured values. • Dept. Revenue parcel data of locations and values of commercial & residential properties. Linked to NRIS Structures database with locations of building stock. • Using GIS – intersect building stock/critical facilities with hazard areas • Determine number and value of buildings at risk • Population exposure – total in hazard area, over 65, under 18
