Step 4a: Identify areas of special consideration.

Special consideration areas are those locations (preferably at the neighborhood level) where individual resources are minimal and personal resources for dealing with hazards can be extremely limited. These areas could be most dependent on public resources after a disaster and thus could be good investment areas for hazard mitigation activities. Identify special consideration areas by utilizing existing low-to-moderate income designations for community development grants or by analyzing key census data categories. 

Examples of Special Consideration Areas

    people
  • Minority Populations: Indicates potential language or cultural considerations.
  • Percent Households below Poverty: Indicates limited resources.
  • Percent Population over Age 65: Indicates possible mobility or cultural considerations.
  • Percent Single Parent with Child Families: Indicates special child care considerations.
  • Percent No High School Diploma: Indicates possible need for personal interactivity in leiu of written communication.
  • Percent Households with Public Assistance Income: Indicates households likely to require public disaster aid.
  • Percent Housing Rental: Indicates households where contents are least likely to be insured.
  • Percent Housing Units with No Vehicle Available: Indicates possible mobility considerations.

Step 4b: Identify intersections of special consideration areas with high-risk areas.

To further target areas for potential hazard mitigation activities, you should identify special consideration areas that are located in high-risk areas. This will also help to determine which mitigation strategies should be focused on the different neighborhoods. Overlay the special consideration neighborhoods with the hazard risk consideration areas.

Step 4c: Conduct a general inventory of special consideration/high-risk locations.

To help prioritize potential mitigation options, conduct a general inventory of structures in the special consideration/high-risk intersections. By providing a count of residential units within these areas, you can summarize the special consideration households to be targeted for assistance and indicate your level of societal vulnerability to each hazard. You may also wish to identify and target these structures for analysis in the future.
