The verbiage in the vulnerability assessment of the State Mitigation Plan changed dramatically. Vulnerabilities themselves have not changed significantly.
HIRA Change Highlights HAZUS-MH used for Flood, Hurricane Wind, and Earthquake Analysis. Included Derecho Winds in the Hazard Identification. Public Health/Technological/Man-caused Hazard Assessment placed in FOUO Annex. For State level plan, emphasis on the Minor Civil Divisions within each County.

Mitigation Strategy Changes Goals and Objectives reviewed with no changes Mitigation Actions Reviewed by DNREC Coastal Programs to be consistent with Sea Level Rise Adaptation Strategy Total of 76 Mitigation Actions listed in the plan Most State Actions Designed to support actions identified in the Local Mitigation Plans Mitigation Strategy
New Mitigation Actions 1. Support the installation of Emergency Generators as stand-alone mitigation projects. 2. Develop procedures to update and maintain the core HAZUS-MH data. 3. Develop Site Specific Data in high risk flood areas for HAZUS analysis. 4. Develop User Defined Facility Listings for critical facilities not identified as critical in HAZUS-MH. 5. Complete the Sea Level Rise Adaptation Strategy and integrate with other plans. 6. Conduct a Delaware specific Climate Change. 7. Increase the real-time monitoring of water levels in streams, bays and dams. 8. Formalize assistance to coastal communities in developing community resiliency plans. Mitigation Strategy
