Municipal Stormwater Permit

Stormwater Annual Report complete and ready for review

The City of Eugene's draft Stormwater Annual Report (with Appendices) is now ready for public review. The report is an overview of Eugene's Stormwater program and includes a status report for each of the City's best management practices to reduce stormwater pollution. The report also contains updated water quality trends for waterways in Eugene, including Amazon Creek and the Willamette River.

Water quality in Amazon Creek and the Willamette River through Eugene is improving. The City has analyzed samples taken from local waterways for over 20 years and data show decreasing trends for certain metals, nutrients, bacteria and turbidity. These trends toward water quality improvement indicate that the City’s stormwater program is having a positive impact. Certain pollutants continue to be problematic in Eugene’s streams, however, including bacteria and zinc. Sources of bacteria in urban areas include pet waste, so it is important to pick up after pets and dispose of animal waste properly. Zinc, which can be toxic to aquatic life, is commonly found in moss control products. It is especially important to carefully follow the manufacturer’s application instructions shown on the product label.

In the 2020 reporting year, City crews swept over 31,000 miles of streets, cleaned over 9,000 catch basins, and removed 1,070 tons of debris from the piped stormwater system. Other activities included "greenpiping" 17 miles of open waterways and planting over 5,000 linear feet of open waterways with native willows and trees.

Cities and counties throughout the country have stormwater permits, referred to as National Pollutant Discharge Elimination System (NPDES) permits. Any discharges from municipal stormwater systems into creeks and rivers are regulated under the federal Clean Water Act. In Oregon, the NPDES permitting program is administered by the Department of Environmental Quality (DEQ). Eugene's 2020 Stormwater Annual Report provides information on the City's Stormwater program activities conducted from July 1, 2019 through June 30, 2020.
