populations, most of which are located in the 100-year floodplains of the Rocky River and other major drainageways. (These areas are identified on Map B-2, Cabarrus County Areas Vulnerable to Flooding.) B. In 1997, there were 210 structures located in the 100-year floodplains within unincorporated Cabarms County. Using the 1998 Special Census occupancy rate of 85% and average household size of 2.6 persons/household, an estimated 465 persons were residing within the 100-year floodplain in 1997. Table B-3: Building Permits for Cabarrus County Permitting Jurisdiction* January 1993 - December 2001 Structure Type Outside Inside % of Total Total Floodplain Floodplain Permits Permits Site-Built 13,021 39 46.9 13,060 Manufactured 4,105 12 14.8 4,117 Subtotal 17,126 51 61.7 17,177 Non-Residential (church, 10,634 32 38.3 10,666 school, office, etc.) Total 27,760 83 100 27,843 I Source: Cabarrus County Planning 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-3, of the total 27,843 building permits issued in the past eight years, 83 or .3% were issued for structures constructed or placed within the 100-year floodplain. Applying this ratio to the existing $273 million building value .tax base, indicates that approximately $819,000 worth of property improvements within the Cabarms 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 Cabarms County populations and structures. D. As indicated in Table B-3, .3% of the total 17,177 residential building permits issued in the last eight years were issued for structures constructed or placed in the 100-year floodplain. Applying this ratio to the current residential tax base of $214 million(Cabarrus County permitting jurisdiction), would indicate over $642,000 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 CNFIP) provides insurance coverage for flood susceptible properties. Cabarms 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-4. Draft Annex B V.3 B-3 1 June 2002
