Hazard Mitigation

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

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.

What is “Hazard Mitigation”?

Hazard mitigation measures can include structural projects like levees, dams, or building safe rooms…

What is “Hazard Mitigation”?

… non-structural projects like acquisition, elevation, retrofit of buildings, or vegetation management…

What is “Hazard Mitigation”?

…regulatory & policy practices like enacting or enforcing building codes, permits, or land use policies…

What is “Hazard Mitigation”?

…training and educational programs for communities, local and State agencies…

Regulatory Requirements

The Stafford Act - Robert T. Stafford Disaster Relief and Emergency Assistance ActDMA 2000 – Disaster Mitigation Act of 2000HMGP – Hazard Mitigation Grant Program44 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 http://www.fema.gov/government/grant/hmgp/index.shtmThe State of Louisiana Hazard Mitigation Plan: http://gohsep.la.gov/mitigation/statehazmitplan_08/hazmitigatpln_08.htm

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.

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.

Hazard Mitigation Simplified 4 Phase Process

How is the Plan Structured?

Introduction and processIdentification of hazards and threats from natural or manmade sourcesAssessment of risks to populations, property, economiesCritical Facility DataAssessment of capability for hazard mitigationAction plans to reduce riskPlan Implementation and Maintenance

Phase 1 – Organize Resources

Assess Community Support

Build the Planning Team

Engage the Public*

Organize resources and process

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.

Phase 2 – Assess Risks

Risk & Vulnerability Assessment

Hazards – Identification & Profiles

proposed hazardsHurricane/tropical cyclone – flood Hurricane/tropical cyclone – wind

Flood Levee Failure

Earthquake Storm Surge

Tornado Hazardous Materials

Pandemic Cyber Attack

Terrorism/Civil Unrest Hailstorm

Disaster aftermath Subsidence

Severe storms Drought

Lightning Wildfire

Severe Heat/Cold Winter Storm

Risk & Vulnerability Assessment

Flood Risk, high winds and other hazards can be based on historical dataOther hazards (storm surge, subsidence) can be assessed on estimations of future risk

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.

Critical Facilities

Algiers Water PlantAlgiers Water TankAlgiers Intake 1 & 2Carrollton Water PlantCarrollton Intake 1 & 2Carrollton Power Generation Plant*Drainage Pumping Stations (21)East Bank STPMichoud Water TankSewer Pumping Stations (66) *West Bank Sewerage Treatment Plant (STP)

* Not identified in original City plan

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)

Floods Structures prone to less than

1 foot flooding

Structures prone to 1 to 4 feet flooding "Mobile homes in floodplain Critical facilities in floodplain Structures in floodway

Tornadoes Pre-wind code structures Historic buildings Critical facilities

Mobile homes "Pre-wind code critical facilities Overhead power lines

Coastal Storms

Structures near the shoreline Structures in the 100-year floodplain

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 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+ "

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 goalswill be achieved.

Identifying Mitigation Actions and Implementation Strategies

Phase 3 – Develop a Mitigation Plan

1. Review the findings of Phase 1 & 22. Note the causal factors for each hazard3. Note the hazard characteristics4. 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 vulnerability6. Develop a list of problem statements based on these

findings.7. Conduct a local capability assessment8. Develop goals and objectives

Analysis of mitigation actions

Prioritization MethodologyBenefit Cost Analysis (BCA)

S 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.

T Technical Mitigation actions are technically most effective if they provide long- term reduction of losses and have minimal secondary adverse impacts.

A Administrative Mitigation actions are easier to implement if the jurisdiction has the necessary staffing and funding

P 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.

L Legal It is critical that the jurisdiction or implementing agency have the legal authority to implement and enforce a mitigation action.

E Economic Budget constraints can significantly deter the implementation of mitigation actions. Hence, it is important to evaluate whether an action is cost- effective, as determined by a cost benefit review, and possible to fund.

E 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.
