Our environmental engineers design stormwater management systems for municipal and industrial clients. They identify sources of stormwater discharge, characterize stormwater discharge, locate illicit discharges, and map stormwater collection systems. They also prepare Stormwater Drainage Improvement Plans (SDIP), Stormwater Pollution Prevention Plans (SW3Ps), and permit applications.

Our Stormwater Management professionals specialize in identifying problems associated with the performance of existing systems and incorporating unique solutions in the design of improvements. Understanding that upgrades to infrastructure are typically constrained by existing structures, utilities, and transportation features, improvements commonly include the use of trenchless installation and system rehabilitation practices.

We are experienced in addressing challenges associated with drainage throughout the Southeast, including the design of energy dissipation to address excessive discharge velocities and design of pumped discharges to address inadequate grades and tidal influences where required.

Supporting the planning and design of development projects, our stormwater services subscribe to Sustainability and Low Impact Development (LID) initiatives and No Adverse Impact (NAI) practices, mitigating the impacts to both stormwater quality and quantity associated with development or redevelopment. We frequently combine Stormwater Management and its Environmental Services to prescribe Best Management Practices (BMPs) to be used in the design of stormwater facilities.
