Greenville County Potential Flood Damage Assessment

George S. Saussy, III


All accessible 100-year flood zones in Greenville County were investigated by windshield survey during the months of December 1984, January, February, and March 1985. Structures at hazard were evaluated and a potential flood damage dollar-amount was calculated for each structure or group of similar structures. These results are contained in the Appendix. Table 1 provides a summary of the potential damage by tributary/reach. Table 2 rank orders these areas by a formula to identify the major areas at hazard.

The area with the highest potential damage monetarily is the Reedy River between Willard Street and Academy Street ($3,343,200). The damage is primarily to warehouses and light industry. Most of the Reedy River has been studied in depth by a Corps of Engineers study: Flood Plain Information, Reedy River (April, 1972).

The second highest potential damage area is Brushy Creek (Enoree River basin) ($900,200 for four reaches). This area contains 185 single-family dwelling units at hazard. This creek has been studied in depth by a Corps of Engineers study: Detailed Project Report, Brushy Creek, (May, 1982).

The third major hazard area is the Langston Creek tributary running adjacent to Langston Street (FIRM Map #145 AND 145a). Damage to 79 single-family dwelling units and mobile homes was estimated at $342,000.

The fourth major hazard area is Richland Creek tributary #5 between Mohawk Drive and Townes Street. Twenty-three single-family dwelling units were estimated at $237,950.
