9 Hazard Mitigation

10 What is Hazard Mitigation? Any sustained measures undertaken to reduce or eliminate the risks posed by natural and/or manmade hazards on a place and its population. Hazard Mitigation Plan: A plan to reduce a community s risk and exposure to disasters Local governments must have a local hazard mitigation plan to apply for certain federal grant programs

11 What is a Hazard Mitigation Plan? It all boils down to two basic questions: 1.What hazards present the greatest risk to the region and its citizens? 2.What are the most effective ways to reduce those risks? 75% of Louisiana s natural disaster declarations in the past decade involved flooding. Louisiana has more repetitively flooded properties than any other state.

12 What is Hazard Mitigation? Hazard mitigation measures can include structural projects like levees, dams, or building safe rooms

13 What is Hazard Mitigation? non-structural projects like acquisition, elevation, retrofit of buildings, or vegetation management

14 What is Hazard Mitigation? regulatory & policy practices like enacting or enforcing building codes, permits, or land use policies

15 What is Hazard Mitigation? training and educational programs for communities, local and State agencies

16 Regulatory Requirements The Stafford Act - Robert T. Stafford Disaster Relief and Emergency Assistance Act DMA 2000 Disaster Mitigation Act of 2000 HMGP Hazard Mitigation Grant Program 44 CFR 201 Code of Federal Regulations Plan must be submitted to State (GOHSEP) and FEMA for approval. DMA 2000 requires the plan be updated every 5 years More information on HMGP available at The State of Louisiana Hazard Mitigation Plan:

17 Why does the Sewerage & Water Board need a plan? The purpose of this project is to develop a Local Hazard Mitigation Plan (LHMP) that complies with the HMGP (Hazard Mitigation Grant Program) and classifies the Sewerage & Water Board of New Orleans as a single, local jurisdiction. As a single, local jurisdiction with a LHMP, the S&WB is directly eligible for various FEMA grant funding programs and reimbursements. This LHMP represents a new local plan. Prior hazard planning for the S&WB was conducted under the City of New Orleans.

18 Planning Process Overview There is a lot of jargon that is used to describe the planning process. We ll try to be jargon free. This graphic shows the process recommended by FEMA. We ll go thru this step-by-step.

19 Hazard Mitigation Simplified 4 Phase Process

20 How is the Plan Structured? Introduction and process Identification of hazards and threats from natural or manmade sources Assessment of risks to populations, property, economies Critical Facility Data Assessment of capability for hazard mitigation Action plans to reduce risk Plan Implementation and Maintenance

21 Phase 1 Organize Resources Assess Community Support Build the Planning Team Engage the Public* Organize resources and process

22 Phase 2 Assess Risks Risk assessment answers the fundamental question that fuels the natural hazard mitigation planning process: "What would happen if a natural hazard event occurred in this area?" Risk assessment is the process of measuring the potential loss of life, personal injury, economic injury, and property damage resulting from natural hazards by assessing the vulnerability of people, buildings, and infrastructure to natural hazards.

23 Phase 2 Assess Risks Risk & Vulnerability Assessment

24 Hazards Identification & Profiles proposed hazards Hurricane/tropical cyclone flood Flood Earthquake Tornado Pandemic Terrorism/Civil Unrest Disaster aftermath Severe storms Lightning Severe Heat/Cold Hurricane/tropical cyclone wind Levee Failure Storm Surge Hazardous Materials Cyber Attack Hailstorm Subsidence Drought Wildfire Winter Storm

25 Risk & Vulnerability Assessment Flood Risk, high winds and other hazards can be based on historical data Other hazards (storm surge, subsidence) can be assessed on estimations of future risk

26 Vulnerability Assessment As part of the assessment we also: 1.Assess relative importance or criticality of facilities 2.Assess risk to facilities from different hazards, based upon estimated losses The S&WB network is widespread and complex and serves as part of the perimeter defense for the City of New Orleans.

27 Critical Facilities Algiers Water Plant Algiers Water Tank Algiers Intake 1 & 2 Carrollton Water Plant Carrollton Intake 1 & 2 Carrollton Power Generation Plant* Drainage Pumping Stations (21) East Bank STP Michoud Water Tank Sewer Pumping Stations (66) * West Bank Sewerage Treatment Plant (STP) * Not identified in original City plan

28 Critical Facility Mapping S&WB network and Katrina inundation S&WB network population density S&WB network primary care facilities (hospitals) S&WB network emergency services (police/fire/ems)

29 Estimating Potential Losses Loss Estimation Table based on hazard profile Estimate loss to structure Estimate loss to contents Estimate loss of use Estimate human loss Hazard Type Floods Tornadoes Coastal Storms Moderate Criteria (Yellow) High Criteria (Orange) Extreme Criteria (Red) Structures prone to less than 1 foot flooding Pre-wind code structures Structures near the shoreline Structures in the 100-year floodplain Structures prone to 1 to 4 feet flooding "Mobile homes in floodplain Critical facilities in floodplain Historic buildings Critical facilities Pre-flood or pre-wind code structures near the shoreline (including A or X zones) Critical facilities near the shore-line (including A or X zones) " Structures in floodway Mobile homes "Pre-wind code critical facilities Overhead power lines Structures located in coastal V zones Wildfires Structures in close proximity to areas with light or medium fuels with slopes less than 40% Structures in close proximity to areas with medium fuels with slopes 41-60% Critical facilities in close proximity to areas with medium fuels and slopes 41 percent+ Other structures in close proximity to areas with medium fuels and slopes 61 percent+ " Other structures in close proximity to areas with heavy fuels and slopes 41 percent+ "

30 Phase 3 Develop a Mitigation Plan The data gathered in the previous phases and the information revealed in the hazard profiles and loss estimation will be used to develop mitigation goals and objectives. Mitigation goals are guidelines that explain what you want to achieve. Mitigation objectives are statements that detail how those goals will be achieved.

31 Identifying Mitigation Actions and Implementation Strategies

32 Phase 3 Develop a Mitigation Plan 1. Review the findings of Phase 1 & 2 2. Note the causal factors for each hazard 3. Note the hazard characteristics 4. Note which important and/or critical assets identified in Phase 2 are located in hazard areas. 5. Identify specific characteristics of assets in hazard areas that contribute to their vulnerability 6. Develop a list of problem statements based on these findings. 7. Conduct a local capability assessment 8. Develop goals and objectives Plan & Strategy

33 Develop a Mitigation Plan Range of actions considered Existing Structures Future Structures Analysis of mitigation actions Prioritization Methodology Benefit Cost Analysis (BCA)

34 STAPLEE Criteria for Mitigation S T A P L E E Social Mitigation actions are acceptable to the community if they do not adversely affect a particular segment of the population, do not cause relocation of lower income people, and if they are compatible with the community s social and cultural values. Technical Mitigation actions are technically most effective if they provide longterm reduction of losses and have minimal secondary adverse impacts. Administrative Mitigation actions are easier to implement if the jurisdiction has the necessary staffing and funding Political Mitigation actions can truly be successful if all stakeholders have been offered an opportunity to participate in the planning process and if there is public support for the action. Legal It is critical that the jurisdiction or implementing agency have the legal authority to implement and enforce a mitigation action. Economic Budget constraints can significantly deter the implementation of mitigation actions. Hence, it is important to evaluate whether an action is costeffective, as determined by a cost benefit review, and possible to fund. Environmental Sustainable mitigation actions that do not have an adverse effect on the environment, that comply with Federal, State, and local environmental regulations, and that are consistent with the community s environmental goals, have mitigation benefits while being environmentally sound.
