"This Guide summarizes the technical information needed for selecting and implementing cost-effective wind retrofit projects for residential buildings. Implementing the Mitigation Packages in this Guide on existing vulnerable homes within the hurricane-prone regions of the United States will result in their improved performance in high-wind events. This Guide presents mitigation measures in packages. A package is a required set of retrofit measures that must be implemented for a home to provide a consistent level of protection. This Guide identifies three successive protection packages: Basic, Intermediate, and Advanced."
