Winter 2022 Stormwater Maintenance Program

December 5, 2022 - The City's annual stormwater maintenance program is underway, with contractors performing work in urban streams and detention ponds throughout Corvallis through February 2023. The work will focus on Dixon Creek, Dunawi Creek, Oak Creek, Mill Race, Ryan Creek, Lamprey Creek, and Stewart Slough, as well as detention ponds in west and southwest Corvallis.

The annual stormwater maintenance program is managed by the Public Works Department. Regular maintenance of urban streams and detention ponds is essential to preserving the health of these waterways. By trimming and extracting dead trees and removing various invasive vegetation, we can improve stream flow and reduce urban flooding during heavy rain events. Work will also focus on creating snags near waterways, which provide important habitats for birds, insects, and other animals.

A new effort for 2022 will focus on proactive work to monitor ash trees in the urban stream system for signs of emerald ash borer. The City has cataloged approximately 10,000 ash trees in and around the urban stream system in Corvallis, and all of these trees are at risk from emerald ash borer infection. Emerald ash borer was identified in Oregon in July 2022, and its arrival in Corvallis is inevitable.

The annual stormwater maintenance program is expected to wrap up in February 2023. For more information, contact Ted Hart at ted.hart@corvallisoregon.gov or 541-766-6454.
