DBS&A is especially qualified to assess the capacity, functionality, and quality of stormwater systems and develop creative solutions to solve nuisance water problems caused by flooding and/or improper and/or insufficient infrastructure. By assessing the hydrologic and subsurface conditions, our engineers identify and develop cost-effective solutions to drainage issues for public entities, private water systems, landfills, and mines. We can provide sustainable solutions for water volume management, peak flow reduction, and water quality improvement by developing innovative solutions to infrastructure deficiencies through retrofitting of existing structures, creative thinking, and employing sustainability techniques.
Our services include permitting, permit compliance, design, and construction oversight. We have extensive experience supporting the U.S. Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) permit compliance, including Municipal Separate Storm Sewer System (MS4) requirements and Construction General Permit. Our engineers take care to meet all federal, state, and local stormwater design requirements, including flood control hydraulic analysis and point source discharge compliance
requirements. We review and analyze sampling data to establish the significance of illicit and stormwater discharge constituents. Our services include water sampling, infrastructure monitoring, and preparation and implementation of Storm Water Pollution Prevention Plans (SWPPPs). Where appropriate, DBS&A can assist clients in meeting stormwater discharge requirements by performing low-impact development (LID) studies and designs in order to infiltrate, evaporate/transpire, and reuse runoff on site.
