Wake County Hazard Mitigation Plan - January 2020


 GIS was used, to the extent data allowed, to analyze the priority hazards as part of the vulnerability assessment.  Assets at risk to identified hazards were identified by property type and values of properties based on North Carolina Emergency Management’s IRISK Database .  A discussion on climate change and its projected effect on specific hazards was included in each hazard profile in the risk assessment.  The discussion on growth and development trends was enhanced utilizing 2017 American Community Survey data.  Enhanced public outreach and agency coordination efforts were conducted throughout the plan update process in order to meet the more rigorous requirements of the 2017 CRS Coordinator’s Manual, in addition to DMA requirements.



The planning process for preparing the Wake County Multi-jurisdictional Hazard Mitigation Plan was based on DMA planning requirements and FEMA’s associated guidance. This guidance is structured around a four-phase process:

1) Planning Process; 2) Risk Assessment; 3) Mitigation Strategy; and 4) Plan Maintenance.

Into this process, the planning consultant integrated a more detailed 10-step planning process used for FEMA’s Community Rating System (CRS) and Flood Mitigation Assistance programs. Thus, the modified 10-step process used for this plan meets the requirements of six major progr ams: FEMA’s Hazard Mitigation Grant Program; Pre-Disaster Mitigation Program; Community Rating System; Flood Mitigation Assistance Program; Severe Repetitive Loss Program; and new flood control projects authorized by the U.S. Army Corps of Engineers. Table 2.1 shows how the 10-step CRS planning process aligns with the four phases of hazard mitigation planning pursuant to the Disaster Mitigation Act of 2000.
