  1. Tippecanoe County Multi-Hazard Mitigation Plan (MHMP) Area Plan Commission Meeting September 20, 2006 Tippecanoe County Office Building

  2. Why Create a Multi- Hazard Plan? • Disaster Mitigation Act of 2000 • Plan for a disaster before it occurs in order to reduce the physical, social and economic impact of a disaster. • Requires all NFIP communities to prepare a MHMP to be eligible for any future mitigation funding. • Every dollar spent on mitigation saves a community four dollars in damage (on average).

  3. Stage 1: Laying the Groundwork • Create the Planning Committee • 30 members with varied backgrounds • Identify NFIP Communities • 5 out of 7 communities participate locally • Identify and Map Critical/Essential Facilities • Select Hazards for In-depth Review

  4. Identification of Critical Facilities • What is a critical or essential facility? • Where are they? • Tippecanoe County: 76 • Lafayette: 113 • West Lafayette: 26 • Battle Ground: 6 • Clarks Hill: 4 • Dayton: 3 • Shadeland: 5

  5. Hazards Selected • Hazardous Materials • Floods • Tornado/Wind Storms • Severe Winter Storms • Earthquakes • Dam Failures • Utility Failures – Not resulting from another hazard

  6. Hazardous Materials…transportation, storage, industrial / household… • Facts: • 2000-2003 : 111 responses • At least 68 Hazardous Sites • 197 leaking underground storage tanks • Concerns: • Accidents/Contamination • Disruption to freight industry • Long term evacuation

  7. Floods…riverine, flash and urban floods… • Facts: • 10 significant events since 1994 • Damages for Indiana exceed $67 billion. • Concerns: • Property Damage • Secondary events • Buyout money • Loss of life

  8. Tornado / Windstorms…violent rotating columns ofair and straight line winds… • Facts: • 1994 (3 deaths /70 injuries, $5M), 1999 (1 injury & $300,000), 2004 ($1M), 2005 ($10K), 2006 (3 events = $80K total) • 35 tornados & 108 wind events/ thunderstorms since 1959 • Concerns: • Unpredictable nature • Damage to property and lives • Safe rooms & tie downs

  9. Severe Winter Storms…heavy snowfall, high winds, ice, freezing rain and cold temperatures… • Facts: • 17 events since 1994 • $300,000 in damage from one storm in 2005 • Concerns: • Stranded residents & motorists • Lack of food and supplies • Disruption to freight industry • Secondary events

  10. Earthquakes…sudden, rapid shaking caused by shifting and breaking rock below the surface… • Facts: • 1811-1812 Regional earthquakes • 1968 & 1987, no damage • HAZUS • Concerns: • New Madrid Fault • Significant event potential

  11. Dam Failures…overtopping, foundation and structural failure… • Facts: • Dams store, control, divert water and create power • 5 local dams, 2 in surrounding counties • No historical records • Could cause an estimated $80B in damages • Concerns: • At risk river communities • Advance warning plans

  12. Utility Failures…outages not triggered by another event… • Facts: • Only minor local outages • A 2003 outage in the Eastern US resulted in $6B in damages; 40M persons affected • A 1965 northeast blackout caused $25M in damage, duration was 12 hours • Concerns: • Lack heating & cooling • Long term failure • Alternative communication needs

  13. Stage 2: Evaluating Hazards • Calculated Priority Risk Index • Weighted formula used to compare hazards. • Probability (unlikely – highly likely) • Magnitude/Severity (negligible – catastrophic) • Warning Time ( more than 24 hours – less than 6 hours) • Duration (less than 6 hours – more than 1 week)

  14. Stage 3: Public Input • On-line Survey • Property damage • Windstorm/Tornado #1 • Disaster most likely to occur overall • Snow Storm #1 • Disaster most likely to affect them personally • Tornado (Lafayette) Snow Storm (W. Lafayette) • Tornado (Dayton) Ice Storm (Tippecanoe Co.)

  15. Public Input Continued • Additional Information provided by Respondents • Need for published evacuation routes • Education about warning sirens, underline gas lines • List of elderly residents and a system to check on them • Restrictions on housing developments and effort to remove debris to reduce flooding • Multiple power outages in Prairie Oaks Subdivision • Budgeting for snow removal / communication • Forest fire hazard near Happy Hollow Park

  16. Stage 4: Mitigation Projects • Develop Projects and Strategies Based on FEMA’s Goals: • Prevention • Property Protection • Natural Resource Protection • Emergency Services • Structural Control Projects • Public Information

  17. General Mitigation Projects • Mutual Aid Agreements • Public Education & Outreach • Safe Rooms & Shelters • Emergency Warning Systems • Communication Systems • Promote Back Up Generators • Improvements to the Emergency Operations Center • Zoning & Building Codes

  18. Hazard Specific Mitigation Projects • Hazardous Materials • Safety Procedures • Evacuation Routes • Tornado/Wind Storm • Requirements for safe rooms in new developments • Stricter tie-down regulations for mobile homes • Tree Maintenance • Winter Storm • Tree Maintenance

  19. Hazard Specific Mitigation Projects • Earthquake • Add local data into HAZUS program • Dam Failure • Emergency Action Plan • Regular Maintenance & Inspection • Utility Failure • Tree Maintenance • Alternative Emergency Warning & Communication Systems

  20. Hazard Specific Mitigation Projects • Floods • Special projects / studies • Floodplain Management / update ordinance • Buyout program • Stormwater Management / Drainage Systems • Community Rating System • Continued participation in CTPP (map modernization) • Incorporate best management practices to reduce runoff and impervious surface

  21. Stage 5: Adoption • Local Adoption • Resubmit to IDHS & FEMA • Communities Become Eligible for HGMP and PDM Grant Dollars • Implement Mitigation Strategies • Update every 5 years • Planning Committee Meetings • Maintain Databases
