Table 4.8 provides an estimate of the number of pre-FIRM buildings in each jurisdiction. This analysis was prepared using NCEM’s IRISK database and comparing the year built for each structure to the corresponding community’s initial Flood Insurance Rate Map (FIRM) date. The pre-FIRM building counts include all building constructed prior to the year of the initial FIRM. Table 4.8 – Pre-FIRM Buildings by Jurisdiction

The IRISK database also identifies Critical Infrastructure and Key Resources (CIKR) buildings as well as High Potential Loss Properties. These properties were also identified in 2010 and are likely an underestimate of the exposure of current CIKR and High Potential Loss Properties. These properties are detailed in Table 4.9 and Table 4.10, respectively.
