Hazard Mitigation Planning IHazard Mitigation Planning I

Session Name: Hazard Mitigation Planning ICoastal Hazards Management Course

• Signed by the President on October 30, 2000

• Amends the Robert T. Stafford Disaster Relief and Emergency Assistance Act of 1988 (the “Stafford Act”)

• Emphasizes mitigation

Disaster Mitigation Act of 2000(DMA2000) or (DMA Y2K)

Slide 37.1



• Establishes a new requirement for state, local and tribal mitigation plans

• Authorizes HMGP funds for state, local and tribal mitigation planning

• Provides for states to receive increased HMGP funds (from 15% to 20%) if, at the time of the declaration of a major disaster, the states have in effect an approved State Mitigation Plan

DMA 2000 Section 322

Slide 37.2



Under the DMA2000, State Hazard Mitigation Plans must:

1) Identify natural hazards and assess vulnerability and risk

2) Support development of local mitigation plans

3) Provide for technical assistance to local and tribal governments for mitigation planning

4) Identify and prioritize mitigation actions that the State will support, as resources become available

State Hazard Mitigation Plans

Slide 37.3



• Mitigation Planning avoids ad-hoc approach to mitigation

• Mitigation Plans can articulate a vision of resiliency to natural hazards

• Mitigation Plans can help educate the public about hazards and mitigation

• Mitigation Plans can guide decision-makers and policy-makers

• Mitigation Plans can fulfill DMA2000 requirements and thereby qualify

for extra funding.

• Mitigation Plans can facilitate access to many other government programs

• Mitigation Plans can fulfill state planning requirements

Benefits of Hazard Mitigation Planning

Worksheet #1: Hazard Identification and Analysis



Likelihood of OccurrenceLikelihood Frequency of Occurrence

Highly Likely Near 100% probability in the next year

Likely Between 10% and 100% probability in the next year, or at

least one chance in the next 10 years

Possible Between 1% and 10% probability in the next year, or at

least one change in the next 100 years

UnlikelyLess than 1% probability in the next year, or less than one chance

in the next 100 years.



Earthquake: Modified Mercalli Scale

Tornado: Fujita Scale

Nor’Easter: Dolan-Davis Scale

Hurricane: Saffir-Simpson Scale

Flood: Water depth & velocity

Wildfire: Fire line intensity, fire spread & flame length

Measures of Hazard Intensity
