Recovery and Reconstruction After Hurricane
Katrina

• CHOOSING OPTIONS THAT WILL FACILITATE LONG-TERM
  RECOVERY FROM THE August 29-30, 2005 DISASTER

LONG-TERM RECOVERY NEEDS FOLLOWING KATRINA

• NEED DEBRIS REMOVAL AND ENVIRONMENTAL IMPACT
  ASSESSMENTS.
• NEED 500,000 NEW DWELLINGS THAT ARE HURRICANE AND
  FLOOD RESILIENT.
• NEED NEW SCHOOLS THAT ARE HURRICANE AND FLOOD
  RESILIENT.
• NEED NEW HOSPITALS THAT ARE HURRICANE AND FLOOD
  RESILIENT.
• NEED INFRASTRUCTURE THAT IS HURRICANE AND FLOOD
  RESILIENT.

4
GOAL

• TO MARSHAL AND INTEGRATE THE COMMUNITYS STAPLE
  FORCES,..
• GIVING THEM EQUITY IN DESIGNING PROCESSES FOR
  BECOMING HURRICANE AND FLOOD RESILIENT.

5
SMART PROCESSES FOR BECOMING HURRICANE AND
FLOOD RESILIENT

• INCREASING PUBLIC AWARENESS
• IMPROVING PROFESSIONAL EDUCATION AND TRAINING
• EXPANDING MONITORING AND WARNING SYSTEMS

• IMPLEMENTING MODERN BUILDING CODES WITH WIND
  PROVISIONS
• MODERN STANDARDS FOR INFRASTRUCTURE
• STRENGTHENING AND RETROFIT OF EXISTING STRUCTURES
• EXPANDING INTERNATIONAL COOPERATION

6
FACTORS IN SMART RECOVERY RECONSTRUCTION

• SAFETY
• ENVIRONMENTAL GEOLOGY
• URBAN PLANNING
• ENGINEERING
• SOCIAL SCIENCE
• POLITICAL
• ECONOMIC

• CITY DEVELOPMENT
• BUILDING CODES
• LIFELINE STANDARDS
• ENVIRONMENTAL STANDARDS

OBJECTIVES

• TO BECOME RESILIENT TO SEVERE WIND AND STORM SURGE

• TO ADOPT AND IMPLEMENT PUBLIC POLICY MANDATES FOR
  MITIGATION, PREPAREDNESS, EMERGENCY RESPONSE, AND
  RECOVERY AND RECONSTRUCTION

11
OBJECTIVES

• USE STATE-OF-ART TOOLS FOR ASSESSING HAZARDS AND
  RISK (E.G., 100 AND 500 YEAR FLOOD MAPS,
  ENVIRONMENTAL IMPACT ANALYSIS, AND LOSS ESTIMATES
  (HAZUS)

• USE PROVEN TECHNOLOGY FOR REDUCING VULNERABILITY
  IN THE BUILT ENVIRONMENT (E.G., WIND AND WATER
  PROOFING)

12
STARTING POINTS

• IN-COUNTRY BASIC AND APPLIED RESEARCH
• LESSONS FROM THE AUGUST 29-30, 2005 DISASTER

• MAPS
• INFORMATION
• GUIDELINES FOR APPLICATIONS BY EMERGENCY
  MANAGERS, BUILDING OFFICIALS, AND URBAN PLANNERS
