Source: NCEM IRISK Database; GIS analysis performed by WSP Note: These estimates do not account for any historical changes in jurisdictional boundaries. Buildings were classified based on the Initial FIRM date for the current jurisdictional boundaries. The IRISK database also identifies Critical Infrastructure and Key Resources (CIKR) buildings and High Potential Loss Properties. These properties are a subset of the total building inventory and are therefore likely an underestimate of the exposure of current CIKR and High Potential Loss Properties. These properties are detailed in Table 4.10 and Table 4.11, respectively. Table 4.10 – Critical Infrastructure and Key Resources by Type and Jurisdiction
