Enhancing Community Resilience: Tippecanoe County Multi-Hazard Mitigation Plan Overview

This meeting focused on the Tippecanoe County Multi-Hazard Mitigation Plan (MHMP) held on September 20, 2006, aims to prepare communities for potential disasters by implementing proactive strategies. The plan, required under the Disaster Mitigation Act of 2000, involves engaging local communities, mapping essential facilities, and evaluating hazards such as floods, tornadoes, and winter storms. Emphasizing public input and education, it identifies critical risks and outlines mitigation projects to lessen the impact of disasters on lives and property.

  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
