Clark's Creek Targeted Outfall Retrofits - Completed 2016
The Clark's Creek Targeted Outfall Retrofit project addresses water quality improvements through installation of sedimentation and filtration devices at selected stormwater outfalls to reduce pollutant loading into the creek.
Clark's Creek, a three-plus mile creek, meanders through Puyallup and Pierce County. As a true urban stream, it is not able to maintain its health as a natural forested stream would. Clark's Creek has been identified to have high levels of sediment deposits, low dissolved oxygen, high fecal coliform, and elevated water temperatures. To solve these problems, plans called Total Maximum Daily Load (TMDLs) have been developed by Washington Department of Ecology the EPA. These plans require the City, Pierce County, and other involved groups to take action to make the waters in Clark's Creek better. For Puyallup, this means reducing untreated stormwater flows into the creek.
Funded in part by a Washington Department of Ecology water quality grant, this project installed a total of four water quality devices, effectively treating over 40 acres of residential stormwater runoff. Please read on to learn about the three Modular Wetland Systems installed in this project. The 4th water quality device, an EcoStorm Plus, was installed as part of the
Meeker Creek Restoration project.
