HAZUS a planning application

• How can we plan to minimize damage and loss of
  life to prevent natural hazards from becoming
  natural disasters?

7
What Is HAZUS-MH
HAZUS-MH is a planning tool that estimates
damage and losses from natural hazards

• It is a planning tool, NOT an engineering tool
• Engineering-level data (i.e. Hydrology
  Hydraulic studies for Flood modeling) can be
  input to increase accuracy, but results still
  produce planning-level estimations
• It estimates physical damage economic losses
• It assesses population needs related to emergency
  management
• It allows users to compare results from different
  study case scenarios, including those that result
  from specific mitigation actions (useful for
  benefits analysis)

8
Technical Components

• Software Custom GIS (geographic information
  system)
• Runs on ESRI products ArcGIS and Spatial Analyst
• ESRI products must be acquired separately
• Spatial Analyst required for Flood Model only
• HAZUS-MH is free from FEMA
• Current HAZUS-MH version (MR3) runs on ArcGIS 9.2
• Previous HAZUS-MH version (MR2) runs on ArcGIS
  9.1
• Data National data sets
• Inventory of assets (buildings, infrastructure,
  population/demographics, etc.)
• Users may modify data sets or model factors
• Users may add their own data

9
Outputs

• Results can be viewed mapped many different
  ways
• Including running mitigation scenarios to compare
  results
• Inventory includes many different classifications
  of general building stock (by occupancy, by
  building type), essential facilities (several
  types), transportation systems (several types),
  demographics and more
• Local data and more sophisticated HAZUS
  techniques enhance the analysis

12
Preparedness

• Develop emergency response plans
• Temporary housing
• Debris removal
• Emergency power and water
• Emergency medical services
• Evacuation/emergency route clearance
• Organize response exercises

13
Response

• Post-disaster damage assessment and
  ground-truthing
• Estimate sheltering needs
• Identify critical transportation outages
• Identify critical facilities

15
Mitigation

• Identify at-risk communities and populations
• Mitigation Measures
• Strengthen existing structures
• Strengthen window/door openings and siding
• Mitigation Programs
• Adopt and enforce hazard-resistant building codes
• Land use planning

16
Recovery

• Recovery action planning
• Long-term economic recovery planning
• Post-disaster building inspection capability
• Housing recovery strategy

17
State Mitigation Plan

• The Florida Hazard Mitigation Plan provides a
  framework for linking pre- and post-disaster
  mitigation planning and measures with public and
  private interests to ensure an integrated,
  comprehensive approach to disaster loss
  reduction.
• HAZUS used extensively for review and analysis of
  hazards and risks.

19
Annual Hurricane Exercises

• HAZUS is used for annual Hurricane Exercises

Florida Catastrophic Planning Project

• The Florida Catastrophic Planning Project
  considers two catastrophic events a breach of
  the Herbert Hoover Dike around the waters of Lake
  Okeechobee and a Category 5 hurricane making
  landfall in South Florida, which has a population
  of nearly seven million.

HAZUS Data and Analysis Used for Structural
Damage from Wind
Percent of Building Stock by Wind Damage Category
23
Additional use of HAZUS Building Stock Data

• Debris calculations were performed using the
  Dewberry Disaster Assistance Response and
  Recovery Technology (DARRT) for Lee and Palm
  Beach Counties and a modified United States Army
  Corps of Engineers debris model for all others.
• Except where the DARRT model was used, all
  building stock data on which estimates are based
  is from the HAZUS regional database.

24
Impact on Major Highway Bridges

• Impacts on bridges were modeled in HAZUS using
  SLOSH outputs from the National Hurricane Center

HAZUS in the News
31
This Hurricane Season

• 100 year and 500 year flood analyses run for most
  Florida counties (results and HPRs to be made
  available via floridadisaster.org/gis
• FEMA Region 4 provided updated essential
  facilities inventory based upon Homeland Security
  Infrastructure Program
• Continuing development integrating SLOSH storm
  surge and depth grids for use within HAZUS

32

Comprehensive Data Management
The standardized role-based application to update
statewide HAZUS-MH datasets

Training November 17-21, 2008

Why use SLOSH?

• Use the existing partnership with NOAAFEMA
  doesnt have surge modeling expertise
• SLOSH is simplified and independently valid to
  within 20 of observed surge heights
• Using SLOSH MOMs, the US is covered!
• FEMA already pays for SLOSH basin updates, why
  pay for separate model development?
• Thousands of hurricane scenarios already run,
  just need to do damage estimates

34
Why use SLOSH?

• HES Zones
• Cat 1
• HAZUS Loss TBD
• Cat 2
• Cat 3
• Cat 4
• Cat 5
