toThe Department of Facility Maintenance has been working with stakeholders since 2019 to develop a Storm Water Fee (SWF) for Oʻahu to support the island's stormwater management needs. The proposed fee will apply to properties with 300 or more square feet of impervious surface, such as rooftops, driveways, and parking lots. The SWF will fund the Storm Water Enterprise Fund, ensuring dedicated revenue for managing and maintaining the island's stormwater system, which includes activities like stream cleaning, beach mouth openings, and stormwater pollution control.
The SWF fee will be based on the amount of impervious surface on each property, which serves as a proxy for the stormwater runoff it generates. The department has developed a rate model to assess different rate structure options and service levels. The model takes into account stormwater operation and maintenance services, as well as capital projects for controlling stormwater volumes and addressing pollutants. The proposal includes stakeholder engagement with residents, businesses, and community groups to gather input and assess the potential impacts on different property types. The goal is to create a more equitable and sustainable funding system for stormwater management on Oʻahu.

toTrash negatively affects water quality, ecosystems, and aesthetics, and can cause beach closures and flooding by clogging waterways. Accurately measuring trash loads in streams is difficult due to reliance on land-use assumptions rather than real storm data or specific watershed conditions. Trash is often linked to sediment movement, as seen in urban flood control systems where both accumulate. This presentation explores methods to capture both trash and sediment, with case studies including a complex transboundary watershed in Tijuana discharging into San Diego. Data from cleanup and dredging efforts reveal variations in trash density and composition, which are crucial for designing effective mitigation systems. The session highlights practical projects and lessons applicable across different watershed types.

toThe stormwater regulatory landscape is evolving to address growing concerns about water quality and environmental protection. Recent trends show agencies moving towards stricter and more comprehensive regulatory frameworks. Key changes include:
1) EPA Actions: The U.S. Environmental Protection Agency (EPA) is issuing stormwater permits under its residual designation authority for previously uncovered commercial, industrial, and institutional sources.
2) Supreme Court Rulings: Key decisions are shaping the interpretation of the Clean Water Act, particularly in relation to groundwater and surface water connections, and enforcement of discharge permits.
3) Emerging Contaminants: Increasing focus on new pollutants, like PFAS, microplastics, and 6PPD-quinone, which will influence future stormwater regulations and permits.
These changes, driven by both judicial decisions and evolving regulatory priorities, highlight the need for municipalities and industries to stay ahead of stormwater compliance challenges.

A current study focuses on integrating blue-green stormwater infrastructure (BGSI) with traditional grey infrastructure to manage flooding in the Lakeview, Lake Vista, and Lake Shore neighborhoods. The study uses hydrologic and hydraulic modeling to assess flood risk and identify priority areas.
A BGSI toolbox was developed in collaboration with city partners, incorporating practices like wet ponds, dry detention basins, underground detention, bioretention areas, and permeable pavements. These solutions aim to reduce flooding, improve water quality, and mitigate urban heat islands. This approach exemplifies how combining nature-based and traditional solutions can enhance urban resilience and adaptability in the face of future flooding challenges.
