The Ostrich Creek basin is approximately 14 acres of heavily urbanized area, with runoff from roadways, commercial and residential uses with most of the stormwater flowing to Ostrich Creek without treatment. Kitsap County Public Health District has a No-Contact order for the stream due to high fecal coliform bacteria levels. Other contaminants from the roadways and developments are metals (dissolved copper and zinc), petroleum, fertilizers, pesticides, sediment, and polycyclic aromatic hydrocarbons (PAH’s). The City will be installing 14 biopods at key points in the basin to be able to treat stormwater before sending it to Ostrich Creek.
Project Schedule (Updated June 30, 2021)
The original water quality component was to have been modular wetland systems (MWS), however due to cost - these have been replaced by biopods. This revision and several design modifications have delayed the project by several months. Drawing revisions have been completed and submitted to the Department of Ecology (DOE) for review and approval. With DOE approval, the project will be bid in late summer with construction in the fall of 2021.
