As an NPDES MS4 permit holder, Greenville County has been required to conduct sampling/monitoring for over a decade. Rather than a “check-the-box” compliance approach, the County has implemented one of the most innovative, continuous monitoring networks in the southeast. The County currently operates and maintains 12 real-time water quality stations, complimented by an additional 17 continuously reporting rainfall gages. The network includes the use of YSI multi-parameter datasondes/sensors, nutrient analyzers, and cellular remote telemetry. The data has been integral for permit compliance, post-storm damage assessment, floodplain model calibration, and for negotiating/evaluating a draft nutrient TMDL. More recently, the County has deployed 3 real-time buoy systems with water quality sensors in a downstream lake to compliment the in-stream data and for further evaluation of the draft nutrient TMDL. The data from the network has been instrumental in the identification of probable pollutant sources and for soliciting support from EPA and over 20 additional local stakeholders in seeking an alternative to a TMDL.
“Let the Floodplains Flood”
- Paula Gucker, Assistant County Administrator for Community Planning, Development and Public Works, Greenville County
- Hal Clarkson, PE, CFM, Woolpert Inc.
Like many communities, Greenville County, SC is a participant in the National Flood Insurance Program (NFIP). Greenville County, however, is more than just a passive participant in the NFIP – they have established a program that proactively reduces flood risk. In just the last 15 years, Greenville has facilitated the acquisition of over 160 at-risk or damaged properties, upgraded approximately 75 bridges/culverts, returned more than 50 acres to natural floodplain and much more. This initiative has paid dividends to the County in terms of reduced liability, enhanced service, and a reduction in repair, replacement, and emergency response costs. But the benefits have extended well beyond the financial and operational benefits to County Government. Lives have been restored, homes have been removed from high risk areas, and roads have an improved level of service. Greenville County is truly managing their floodplains to reduce risk and enhance the quality of life of its citizens. Come hear how the County has created a successful floodplain management program that is embraced by political leaders and supported by the community.
