Stormwater Citizen Suits: Strategies to Reduce Litigation Risk
Michael Campbell, Partner, Stoel Rives LLP
Ada Banasik, Principal Engineer, Maul Foster & Alongi
This session focuses on the intersection of the importance of stormwater and stormwater management and the importance of stormwater BMP maintenance. Over the past two decades, Oregon has invested heavily in stormwater infrastructure—treatment vaults, ponds, swales, filtration systems, proprietary devices, and green infrastructure—to protect rivers, drinking water sources, fisheries, and communities. While these systems often operate unnoticed when functioning properly, failures can result in contaminated waterways, flooding, habitat degradation, and increased public costs. Consistent maintenance is essential for protecting public health and natural resources and preserving the value of Oregon’s stormwater infrastructure.
