Stormwater Programming and Capital Improvements Investigations
In 2008, the Town of Stallings, North Carolina, developed a comprehensive Storm Water Management Program (SWMP) in compliance with the NPDES Permit for their Municipal Separate Storm Sewer System (MS4). EMH&T worked with the town to develop a program to meet the federally-mandated requirements for quality of stormwater discharges from the town’s storm sewer system. The program includes provisions for both quality and quantity of stormwater runoff within the community, including specific best management practices (BMPs) for each of the six minimum control measures required for compliance with their SWMP. EMH&T worked with the Town to inventory their storm sewer outfalls, drainage areas, and receiving streams, and to create base maps and dry weather screening of the outfalls. EMH&T also established a procedure for tracing sources of illicit discharge and for removing the sources, where possible. More recently, EMH&T completed an investigation of ten stormwater problem areas within the town and developed planning-level solutions, costs and a prioritization scheme for implementing those solutions. In addition, we were asked by the City to provide a thorough engineering investigation of a specific flooding location within the residential subdivision, where a home was being subjected to flooding from an adjacent watercourse. As part of this investigation, we completed a data collection and analysis process to evaluate the local storm system and open channels within the study area.
