Step 7a: Identify areas of undeveloped land and their intersection with high-risk areas.
New Hanover County’s parcel-level land use database was used to identify the county’s undeveloped land. By applying risk summary scores to the undeveloped parcels, New Hanover County defined their high-risk undeveloped land areas as potential target areas for future hazard mitigation considerations.

Step 7b: Inventory high-risk undeveloped land.
Satellite-based land cover images were used to determine the land cover types for New Hanover County’s undeveloped parcels. This information gives you some indication of the type and amount of development potential that exists throughout the county.

Zoning classifications can also provide information about the development potential for undeveloped land areas. New Hanover County’s zoning designations were used to identify the maximum legal development densities associated with undeveloped land tracts. This information can now be used to identify possible policy changes to minimize development or require additional structural mitigation for future construction in high-risk locations.
Below are the detailed zoning classifications for the undeveloped high-risk parcels. These zoning classifications are a combination of city and county zoning and are intended only for general information purposes. Individual jurisdictions should be contacted for specific parcel-level zoning information.

Step 7c: Assess the status of your existing flood insurance program participation.
New
Hanover County’s participation in the National Flood Insurance
Program is concentrated primarily along the coast. One of the
mitigation strategies that the county may wish to pursue is to target
flood insurance education programs in the high-risk areas located in
other portions of the county. Other data such as the percentage of
mobile homes or the age of the housing stock can help to further
target locations for this type of educational effort.
