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.
