  3. State of Louisiana Hazard Mitigation Plan Update Hazard Mitigation Planning

  4. State of Louisiana Hazard Mitigation Plan UpdateWhat is “Hazard Mitigation”? Any measures undertaken to reduce the risks posed by natural and/or manmade hazards on a place and its population.

  5. State of Louisiana Hazard Mitigation Plan UpdateWhat is “Hazard Mitigation”? Hazard mitigation measures can include structural projectslike levees, dams, or building safe rooms…

  6. State of Louisiana Hazard Mitigation Plan UpdateWhat is “Hazard Mitigation”? … non-structural projectslike acquisition, elevation, retrofit of buildings, or vegetation management…

  7. State of Louisiana Hazard Mitigation Plan UpdateWhat is “Hazard Mitigation”? …regulatory practiceslike enacting or enforcing building codes, permits, or land use policies…

  8. State of Louisiana Hazard Mitigation Plan UpdateWhat is “Hazard Mitigation”? …training and educational programsfor communities and State agencies…

  9. State of Louisiana Hazard Mitigation Plan UpdateWhat is a “Hazard Mitigation Plan”? • Hazard Mitigation Plan: A plan to reduce a community’s risk and exposure to disasters … which is different from an … • Emergency Operations Plan(EOP): A plan to guide a community’s response to an emergency or disaster

  10. State of Louisiana Hazard Mitigation Plan UpdateWhat is a “Hazard Mitigation Plan”? • A Hazard Mitigation Plan is typically written before hazard events occur (pre-disaster) • Hazard mitigation projects can be implemented either before or after a disaster (pre-disaster or post-disaster).

  11. State of Louisiana Hazard Mitigation Plan UpdateWhy do We Need a Plan?

  12. State of Louisiana Hazard Mitigation Plan UpdateWhy do We Need a Plan?

  13. State of Louisiana Hazard Mitigation Plan UpdateWhy do We Need a Plan? • In the last 10 years, there have been 16 Presidential Disaster Declarations for natural hazards in Louisiana. • The total federal assistance paid for these disasters is over $26 billion.

  14. State of Louisiana Hazard Mitigation Plan UpdateWhy do We Need a Plan? • The actual damages far outstrip federal assistance – the costs of Katrina and Rita alone are estimated between $90 and $140 billion. • And then there is the human cost – nearly 1500 deaths, and nearly 200,000 people still displaced

  15. State of Louisiana Hazard Mitigation Plan UpdateWhy do We Need a Plan? • 75% of Louisiana’s natural disaster declarations in the past decade involved flooding. • Louisiana has more repetitively flooded properties than any other state – double the next-highest state. • Louisiana is also prone to damaging high winds, ice storms, HAZMAT releases, and other hazards.

  16. State of Louisiana Hazard Mitigation Plan UpdateWhy is the Plan Important? • The Plan satisfies requirements of the Disaster Mitigation Act of 2000 (DMA 2000), keeping Louisiana eligible for millions of dollars of pre- and post-disaster grants.

  17. State of Louisiana Hazard Mitigation Plan UpdateWhy is the Plan Important? • Between 1995-2004, Louisiana received more than $40 million from the Hazard Mitigation Grant Program (HMGP); it received nearly $170M in HMGP after Katrina and Rita • The State is also competitive for Pre-Disaster Mitigation (PDM) and Flood Mitigation Assistance (FMA) grants, winning nearly $8 million since 1998.

  18. State of Louisiana Hazard Mitigation Plan UpdateWhy is the Plan Important? • It helps focus attention on important issues for communities and State agencies • It leads to better partnerships between the State and communities • It initiates realistic and meaningful steps to address the issues.

  19. State of Louisiana Hazard Mitigation Plan UpdateDon’t we already have a Plan? Yes! …but DMA 2000 requires the Plan be updated every three years and the current plan expires in April 2008. Much of this 2008 Plan Update is similar to the 2005 Plan. Implementation of the 2005 Plan was constrained by disruption of Hurricanes Katrina and Rita.

  20. State of Louisiana Hazard Mitigation Plan UpdateIs this the end of the process? No! …it is closer to the beginning than the end. This presentation ends with “Next Steps” including how you can stay involved.

  21. State of Louisiana Hazard Mitigation Plan Update State of Louisiana Hazard Mitigation Plan Update

  22. State of Louisiana Hazard Mitigation Plan UpdateHow was the Plan Developed? There is a lot of jargon that is used to describe the planning process. This graphic shows the process recommended by FEMA.

  23. State of Louisiana Hazard Mitigation Plan UpdateHow was the Plan Developed?

  24. State of Louisiana Hazard Mitigation Plan UpdateHow was the Plan Developed?

  25. State of Louisiana Hazard Mitigation Plan UpdateHow was the Plan Developed?

  26. State of Louisiana Hazard Mitigation Plan UpdateHow was the Plan Developed?

  27. State of Louisiana Hazard Mitigation Plan UpdateHow was the Plan Developed? It all boils down to two basic questions: • What hazards present the greatest risk to the State and its citizens? • What are the most effective ways to reduce those risks?

  28. State of Louisiana Hazard Mitigation Plan UpdateHow is the Plan Set Up? • Introduction and process (Secs. 1-3 & Appxs. A-C, I-J) • Identification of hazards from natural or manmade sources (Sec. 4 & Appx. D) • Assessment of risks to populations, property, economies (Secs. 5-6 & Appxs. E-F) • Assessment of state/local capability for hazard mitigation (Sec. 7 & Appxs. G, K) • Action plans to reduce risk (Secs. 8-10 & Appx. H)

  29. State of Louisiana Hazard Mitigation Plan Update Hazard Identification

  30. State of Louisiana Hazard Mitigation Plan UpdateHazard Identification Natural Hazards considered included • Ice Storms • Lightning • Severe Heat/Cold • Storm Surge • Subsidence • Wildfire • Drought • Earthquake • Flood • Hailstorm • High Winds (Hurricane) • High Winds (Tornado)

  31. State of Louisiana Hazard Mitigation Plan UpdateHazard Identification Manmade Hazardsconsidered included: • Dam Failure • Levee Failure • Hazardous Material (HAZMAT) Incidents

  32. State of Louisiana Hazard Mitigation Plan UpdateHazard Identification Hazard profiles help determine which hazards pose the greatest threat to Louisiana. Hazards like Floods affect specific areas.

  33. State of Louisiana Hazard Mitigation Plan UpdateHazard Identification Hazards like High Windscan affect the whole state, but the severity of the hazard declines from south to north.

  34. State of Louisiana Hazard Mitigation Plan UpdateHazard Identification Based on a review of hazard profiles, the hazards assessed in the Plan are: • Subsidence • Wildfire • Dam Failure • Levee Failure • HAZMAT Incident • Flood • High Winds (Hurricane) • High Winds (Tornado) • Ice Storms • Storm Surge

  35. State of Louisiana Hazard Mitigation Plan Update Statewide Risk Assessment

  36. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment The Plan has two parallel Risk Assessment tracks: • Statewide Risk Assessment (by Parish) – the State as a community • State-Owned Assets Risk Assessment – the State as a property owner

  37. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment Ideally, the Statewide RA would consider the effects of hazards on: • Populations and specific demographics • Building stock: residential, commercial, and industrial • Critical facilities: fire stations, police stations, EOCs, clinics, etc. • Infrastructure: Highway bridges, railways, oil and gas pipelines

  38. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment However, the process was limited by existing data. • Hazard data is not consistent across geography and hazards • Facility and infrastructure data is not always consistent • Post-2005 demographics remain unstable

  39. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment Therefore, risk from different hazards were assessed in different ways: • Some hazards (flood, ice storm, high winds, wildfire, HAZMAT release) were assessed using historical data • Others (storm surge, subsidence, dam and levee failure) were assessed based on estimations of future risk.

  40. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment Flood risk, based on historical data including claimsfrom the National Flood Insurance Program

  41. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment Dam failure risk, based on estimating future risk topeople in proximity to dams

  42. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment Finally, the hazards were assessed relative to each other, generating a “composite risk ranking” by parish.

  43. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment Additional analysis included in the Plan: • Risk to mobile homes, key economic drivers, and critical infrastructure • Risk of “secondary” hazard events • Measuring exposure to hazards in different future development scenarios • Consistency of this Plan with local hazard mitigation plans

  44. State of Louisiana Hazard Mitigation Plan UpdateStatewide Risk Assessment Observations and Conclusions: • This assessment provides a basis for comparing effects of the natural and manmade hazards between parishes. • It also provides information to use in integrating these results with local mitigation planning efforts. • “Ground-truthing” or validation of the results is needed at the local level.

  45. State of Louisiana Hazard Mitigation Plan Update Risk Assessment for State-Owned Assets

  46. State of Louisiana Hazard Mitigation Plan UpdateState-Owned Asset RA The Risk Assessment for State-Owned Assets has two parts: • Assess relative importance or “criticality” of facilities • Assess risk to facilities from different hazards, based upon estimated losses

  47. State of Louisiana Hazard Mitigation Plan UpdateState-Owned Asset RA

  48. State of Louisiana Hazard Mitigation Plan UpdateState-Owned Asset RA State-owned critical facilities were mapped and ranked by “criticality.”

  49. State of Louisiana Hazard Mitigation Plan UpdateState-Owned Asset RA This allowed potential impacts on State-owned assets to be compared, including the results for Flood…

  50. State of Louisiana Hazard Mitigation Plan UpdateState-Owned Asset RA … and High Winds. Additional hazards were analyzed for the risks they pose to state-owned facilities
