IHRM Vision



1. HAZARD IDENTIFICATION

IHRM will build upon available data to define and map the physical characteristics of the following natural hazards within North Carolina:

  • Riverine Flooding
  • Coastal Flooding
  • Dam Failure
  • Levee Failure
  • Storm Surge
  • Coastal Erosion
  • Landslide
  • Earthquake
  • Wildfire
  • High Hazard Winds
  • Tornado
  • Snow
  • Ice
  • Hail
  • Drought

2. VULNERABLE SYSTEMS

IHRM will identify the location and attributes of the following systems that may experience loss from a natural hazard:

  • Buildings
  • Critical Infrastructure/Key Resources (CI/KRs)
  • People
  • Economy

Included is an analysis of how these systems are susceptible to each hazard, how failure of one of these systems impacts the others, and the primary consequences that can occur when a hazard does impact.

3. RISK ASSESSMENT


Building upon the Hazard Identification and Vulnerable Systems data, IHRM will establish an approach for estimating the likelihood of each of the hazards impacting, the likelihood and severity of adverse consequences, and the total expected losses from a parcel up to a statewide perspective.  Metrics, necessary to measure and communicate the existing baseline of risk and report how risk changes over time or based upon proposed mitigation actions, will be established as well.

4. COMMUNICATION

Computer-based tools will be developed and tested that will (1) perform the risk analysis for a specific parcel or aggregation thereof and (2) communicate the hazards that are most likely to impact, the magnitude of loss expected, the appropriate alternatives available to mitigate the risk, and the benefits versus costs of these alternatives.  These tools will be directed to two primary user groups: (1) home and business owners as a web application and (2) mitigation planners as either a web or stand-alone application.

In addition, the tool will support local government hazard mitigation planners in producing updated Hazard Mitigation Plans consistent with FEMA and State requirements.

5. MITIGATION

IHRM will develop an enhanced approach for the local hazard mitigation planning process leveraging the analytical/communication tools.  The tools and revised planning approach will be demonstrated in four pilot counties- Durham, Edgecombe, Macon, and New Hanover– to develop comprehensive, FEMA-approved updates to their existing local hazard mitigation plans.  Additionally, a systematic assessment of the vulnerability of CI/KRs throughout the state will be performed to identify and prioritize the CI/KRs based on the risk of significantly disrupting the functioning of government and business alike.
