The City's stormwater division works to control flooding, protect water quality, improve creek and lake habitat, and comply with state and federal requirements for clean water. Actions undertaken include maintaining and cleaning stormwater facilities to avoid flooding, public education and outreach, responding to pollutant spills, inspections, reviewing stormwater plans for new development, and managing municipal operations to protect stormwater. To accomplish these tasks, revenue is required. In 2019, the MLT stormwater rate study reviewed stormwater division costs to deliver services and capital improvements against the revenue received from stormwater service fees. The stormwater rate study report provides a detailed explanation of that analysis.
