Why have we developed a BGADD Regional Hazard Mitigation Plan?: 

Why have we developed a BGADD Regional Hazard Mitigation Plan?

Disaster Mitigation Act of 2000: 

Disaster Mitigation Act of 2000 On October 30, 2000, the President signed into law the Disaster Mitigation Act of 2000 (DMA 2000)

Slide5: 

DMA 2000 placed new emphases on local mitigation planning: (1) By requiring local governments to develop and submit pre-disaster mitigation plans as a condition of receiving Hazard Mitigation Grant Program (HMGP) and Pre-Disaster Mitigation project funding. (2) Developing experimental multi-hazard maps to better understand risk (3) Establishing state and local government infrastructure mitigation planning requirements

However,…: 

However,… Besides fulfilling the requirements of the law, a major purpose for developing this Regional Hazard Mitigation Plan is to provide a working document for mitigating, or reducing / eliminating, natural hazard effects on local communities.

Slide7: 

Which do you think is the most damaging natural hazard in the BGADD?

Hazards That Affect the BGADD(See packet page 41-45): 

Hazards That Affect the BGADD (See packet page 41-45) Floods and Flooding Earthquakes Tornadoes Severe Winter Storms Landslides Thunderstorms Wildfires Karst / Sinkholes Dams / Levees Failures Drought / Heat Waves

Slide9: 

From 1994 to 2003 – There were 248 floods in the BGADD and they caused $40M in damage; about $4M per year; and about $161,000 per flooding event. (See packet pages 93-98)

Slide10: 

From 1995 to 2004 – 22 Winter Storms in the BGADD caused $36M in damages; about $3.6M per year; and about $1.7M per winter storm event. (See binder pages 193-196)

Slide11: 

From 1964 to 2003 – 92 tornadoes in the BGADD which caused $106M in damages; about $2.6M per year; and about $1.2M per tornadic event. (See packet pages 140-143)

3.3 Hazard Risk Assessment: 

3.3 Hazard Risk Assessment A Risk assessment is a process for evaluating risk as defined by: (1) the probability and frequency of occurrence of a hazard event, (2) the exposure of people and property to the hazard, and (3) the consequences of that exposure. (Binder page 40)

Risk Assessment: 

Risk Assessment A risk assessment process may utilize scientific or historical information to determine if a future natural hazard could or would cause harm to property or persons in a designated area. (Binder page 40)

BGADD Flood Risk Assessment Data:

Flood Information: 

Flood Information Background information about floods – binder pages 48 to 54 Historical Flood Data – binder pages 55 to 92 Compiled BGADD Flood Statistics – packet pages 93 to 96, and A culminating profile of floods in the BGADD – packet page 98

Definition and Description of Flood: 

Definition and Description of Flood “An overflow of water onto lands that are used or usable by man and not normally covered by water. Floods have two essential characteristics: The inundation of land is temporary; and the land is adjacent to and inundated by overflow from a river, stream, lake, or ocean.” (USGS Water Science Glossary of Terms, (http://ga.water.usgs.gov/edu/dictionary.html) (See packet page 48)

Slide17: 

(See packet pages 93-96, 98) 3.3.2-a.10 Profile of a Future Flood in the BGADD Based on best available historical data, (1) In the entire 17-county Bluegrass Area Development District area, 11 days of flooding may be expected every year. Historically, the area experienced 112 days of flooding in the last ten years. (2) A future flood will cause property and crop damage costing an average of about $161,000 per event, however, over half of the recorded flood events will show $0 costs (based on National Climatic Data Center data.) The most costly flood event affecting BGADD counties (12 of 17 counties) in the past ten happened in early March 1997. The flooding damages totaled $5.7M, or an average of $475,000 per county. (3) There is an eighty-seven per cent (87%) probability that a flood event will occur annually between February 1st to July 31st. Twenty five percent of all flood events occur in the month of May.

BGADD Tornadoes Risk Assessment Data:

Fujita Tornado Scale: 

Fujita Tornado Scale The Fujita Scale is used to rate the intensity of a tornado by examining the damage caused by the tornado after it has passed over a man-made structure. (See packet page 124.)

3.3.3 Hazard Vulnerability Assessment : 

3.3.3 Hazard Vulnerability Assessment Calculation of the level of vulnerability that certain areas will have during a future hazard event.

Vulnerability Assessment Steps: 

Vulnerability Assessment Steps (1) Delineate the natural hazard-prone zones, in the cases where hazard-boundaries can be determined. (2) Determine current replacement value of hazard-prone zone structures. (3) Create charts depicting four percentage levels of loss to provide a sense of potential damage losses relative to severity of hazard

What did we do with all of this information?

Sixteen County Hazard Mitigation Plan Development Teams (CHMPDTs): 

Sixteen County Hazard Mitigation Plan Development Teams (CHMPDTs) Met for eight monthly community-based planning meetings, discussed the hazard information, one hazard at a time, gathered more data, and

The sixteen CHMPDTs collectively proposed:: 

The sixteen CHMPDTs collectively proposed: Seven Hazard Mitigation Goals Nineteen Objectives Thirty Actions, and 446 Mitigation Projects to mitigate the effects of ten natural hazards (See binder pages 391-400 and 407-508)

Notation: 

Notation “Implementation of actions by the local government will depend heavily on the local fiscal ability and funding opportunities available to the jurisdictions to implement the actions, thus this Regional Hazard Mitigation Plan is to serve as a guide and not a mandate to implementation of the projects.” (See binder page 509, section 3.4.2-c)
