  4. 4. Wetlands Reduce Flooding? Coastal wetlands are estimated to have saved $625 million in flood damages during Hurricane Sandy. - COASTAL WETLANDS AND FLOOD DAMAGE REDUCTION Using Risk Industry-based Models to Assess Natural Defenses in the Northeastern USA
  5. 5. Holistic Coastal Resiliency Enhancement &Community Risk Reduction in the Great Marsh
  6. 6. Community Resiliency Planning 1. Develop community climate vulnerability assessments 2. Conduct comprehensive public outreach & engagement 3. Publish an Implementation Roadmap & Climate Adaptation Plan Project Area: Salisbury, Newbury, Newburyport, Essex, Ipswich, & Rowley. Climate Adaptation Plan Town-specific Climate Vulnerability Assessments Adaptation Strategy Summary Implementation Roadmap
  7. 7. Adaptation Planning Step 1:  Reviewed and synthesized over 50 documents  Identified a full array of adaptation strategies
  8. 8. Adaptation Planning Step 2: Expand the list of strategies through facilitated process Adaptation Catalog reviewed by stakeholders and local input incorporated
  9. 9. Adaptation Planning Step 3:  Adaptation Catalog  Identified top-strategies for assets in each community  Technical input
  10. 10. Adaptation Planning Step 4: Create Detailed Adaptation Strategy Summary Document To include strategies that reduce vulnerability of…  Specific assets  Natural resources  Overall community/economics/demographics
