What Is DMA 2000?

3
The federal Disaster Mitigation Act of 2000 (DMA
2000) focuses on

• Mitigation before, rather than after, disasters
• Ties future mitigation funding to cities,
  counties, and special districts having Local
  Hazard Mitigation Plans completed

4
What has ABAG done?

• 1 DOCUMENTED local government participation
  in a variety of forums
• 2 Produced interactive HAZARD MAPS for Bay
  Area local governments
• 3 Provided interactive RISK ASSESSMENT
  information specific to Bay Area jurisdictions

5
What has ABAG done?

• 4 Provided a variety of MITIGATION actions
• - that can be adopted (in whole or in part) by
  cities, counties, and special districts
• - to reduce their risks to a level acceptable
  in their communities

6
What do local governments need to do?

• 1 Look at the HAZARD maps and EXPOSURE
  information (as demonstrated in this PowerPoint)
• 2 Meet with staff to choose the mitigation
  strategies that are appropriate
• 3 Allow the public an opportunity to
  comment on those choices (at, for example, a City
  Council meeting)

7
What do local governments need to do?

• 4 Complete the templates for the local
  Resolution and Annex WORD file, and the
  Mitigation Spreadsheet file and send to ABAG with
  contact info
• 5 Wait for comments from FEMA
• 6 Incorporate FEMA changes
• 7 Have the Council or Board adopt the Bay
  Area LHMP and the local Annex

What Is Mitigation?

51
Two ways to deal with hazards

• Increase emergency response capability
• Increase actions taken to reduce or eliminate the
  impacts of future incidents

52
MITIGATION Decisions Costs of ACTION vs.
INACTIONCOSTS vs. LOSS REDUCTION

• Deaths and injury
• Damage property dollar loss
• Disruption downtime due to inoperable
  functioning

53
GOAL To develop a disaster-resistant region by

• Reducing the potential loss of life, property
  damage, and environmental degradation from
  natural disasters, while
• Speeding economic recovery from those disasters.

54
Infrastructure ABAG worked with special
districts and local public works depts. to
develop strategies for each hazard
55
2. Health ABAG worked with county public health
depts. and health experts to develop mitigation
strategies for hospitals, aux. health care
facilities, and envir. health
56
3. Housing ABAG worked with building/fire
depts., SSC, and contractors to develop
strategies outreach
57
4. Economy ABAG worked with building/fire
depts., SSC, and contractors to develop
strategies and outreach
58
5. Government Services ABAG worked with public
works/fire depts., OES, and risk managers to
develop strategies
59
5. Education ABAG worked with State Div of
State Architect, school districts, and the Red
Cross to develop strategies
60
7. Environment - ABAG worked with CEQA,
environmental, and geotechnical specialists
61
8. Land Use focus of CEQA and General Plans

• ABAG worked with CEQA, environmental, Smart
  Growth, and geotechnical specialists

62
Setting Priorities

• Existing Program
• Very High NOW!
• High need money
• Moderate if money
• Under Study
• Not Applicable
• Not Yet Considered
