1. Using HAZUS-MH for Comprehensive Planning Bill Bohn, Tetra Tech June 20, 2007

2. Comprehensive Plan Elements  Data collection  Data analysis  Public participation  Recommendations

3. Data Collection  Collect data on current conditions  HAZUS-MH data may be used as a base but should be updated Inventory data Population data Hazard data Physical environment  Other GIS data

4. Inventory Data  Building occupancies – general and specific  Transportation systems  Critical facilities  Agriculture  Levees and dams (including high hazard)

5. Population Data  Population density  Vulnerable populations –Elderly –Impoverished

6. Hazard Data  Floodplains  Wind speeds  Potential ground motion  Dam breach inundation area(s)

7. Physical Environment Data  Digital Elevation Model  Soils  Landslide susceptibility  Liquefaction susceptibility

8. Other GIS Data  Land use data  Land cover data  Zoning data  Environmental data  Municipal boundaries  Collect and update metadata for all data sets!

9. Data Analysis  Overlay GIS data  Use HAZUS to analyze potential growth sites  Use HAZUS-MH to evaluate new building codes

10. Overlay Examples  Transportation systems on population centers and future growth areas  Population centers and critical facilities on the physical environment features  Building occupancies on land use

11. Potential Growth Areas Analyzed Using HAZUS-MH  Run a flood analysis on future growth sites to show and compare potential losses. Will future development change the floodplain? May need to update physical environment data.  Run an earthquake analysis on future growth sites. Are some areas susceptible to landslide or liquefaction?

12. Potential Building Codes Analyzed Using HAZUS-MH  Use the hurricane wind mitigation options to determine how changing the building codes will affect potential losses in new growth areas.  Use the HAZUS-MH flood model to analyze changes in local floodplain management ordinances.

13. Public Participation  Keep the public informed using maps and tables.  Use maps to help explain the analysis during discussions.  Create interactive maps.

14. Recommendations  Map the community’s vision. Areas of growth and change New transportation Building code changes Land use  Document the analysis completed in HAZUS-MH.  Include metadata in documentation.

15. Conclusions  Although HAZUS-MH is commonly used for mitigation planning it may also be used for comprehensive planning.  HAZUS-MH may be used to support several different elements in the comprehensive planning process.
