Table B -4: Building Permits for Cabarrus County Permitting Jurisdiction* January 1993 — December 2009 Source: Cabarrus County Commerce Department Note: Cabarrus County Permitting Jurisdiction includes the unincorporated portions of the County and the municipalities of Concord, Harrisburg, Midland, Mount Pleasant, and the Cabarrus County portion of Kannapolis. C. As indicated in Table B -4, of the total 45,252 building permits issued in the past sixteen years, 194 or 0.43% were issued for structures constructed or placed within the 100 -year floodplain. Applying this ratio to the existing $7.79 billion building value tax base (buildings only), indicates that approximately $31,945,244 worth of property improvements within the Cabarrus County permitting jurisdiction are currently susceptible to property damage from a flood hazard event. The increased frequency and intensity of natural hazard events over recent years indicates high vulnerability for Cabarrus County populations and structures. D. As indicated in Table B -4, 0.49% of the total 32,643 residential building permits issued in the last sixteen years were issued for structures constructed or placed in the 100 -year floodplain. Applying this ratio to the current residential tax base of $6.13 billion (Cabarrus County permitting jurisdiction), would indicate over $25,128,928 worth of residential property (land and buildings) is currently susceptible to flooding. The future vulnerability to flooding will remain high even if no additional development occurs within flood hazard areas. E. National Flood Insurance Program. The National Flood Insurance Program (NFIP) provides insurance coverage for flood susceptible properties. Cabarrus County has participated in the NFIP under emergency status since July of 1975 and gained full status in May of 1981. Data on current NFIP insurance policies and recent claims are shown in Table B -5. The data shows a very large increase in the number of policies and the values associated with those insured properties. This increase is more attributable changes in the lending industry and requirements imposed by those lenders than additional construction in vulnerable areas. Lending institutions have employed improvements in mapping to determine structures that may be vulnerable and have required the owners of those existing structures to obtain flood insurance.
