Client Service
Aaron leads high profile and complex projects for clients in the municipal, industrial, land development, and applied research sectors. He applies his expertise in environmental regulations, water resources modeling, and stormwater control measures to lead integrated watershed management efforts throughout the West Coast, including green infrastructure/low impact development, stormwater control retrofits, stream protection and rehabilitation, flood risk mitigation, water supply augmentation, and asset management. His work in watershed planning and stormwater compliance has recently led him to focus on innovative data systems for asset management, modeling, streamlined reporting, and decision support, including custom open-source software tools. Through his diverse experiences, he understands a wide range of effective tactics that municipalities and site owners can apply to control stormwater pollutants and manage stormwater assets, and how these elements contribute to their overall watershed management efforts.
To advance the state of the practice, Aaron actively participates in applied research projects for the Transportation Research Board (TRB), Water Research Foundation, U.S. EPA, state agencies, and local municipalities. He has led TRB research on stormwater infiltration, BMP performance, and lifecycle costs, including publication of multiple National Cooperative Highway Research Program reports. His is a leader in the implementation of “smart stormwater” technologies, including supporting Clean Water Services in Washington County, Oregon, with a pilot evaluation of a smart basins for managing stormwater runoff which was highlighted in Environmental Science and Technology (ES&T, Kerkez et al., 2016). In partnership with Washington State University, he led research on bioretention hydraulic control alternatives, and he has supported several private and municipal clients with advancements to engineered soil media ad bioretention design. He has also contributed to award-winning BMP design projects, including the Mill Creek Wetlands (California Regional BMP of the Year). Aaron is one of the leaders of Geosyntec’s Water and Natural Resources practice area and collaborates with professionals across the country.
