The Carli Creek project is a 15-acre water quality facility along the Clackamas River. The project reduces surface water pollutants originating from the surrounding industrial area.
- 120th and Capps Road area
This area is currently served by stormwater infrastructure that conveys runoff to 3 outfalls. Two of these outfalls drain directly to Carli creek. Very little of the runoff is treated to remove pollutants before it enters the storm drainage system.
Stormwater data have revealed the presence of pollutants in this heavily developed watershed. In 2013-14, water quality monitoring showed pollution levels exceeded standards for:
- E. coli
The project includes the construction of channels, ponds, wetlands, and permeable berms to treat stormwater, filtering pollutants before the runoff enters the Clackamas River.
The project includes erosion control and habitat structures for the benefit of fish and aquatic wildlife.
- a meandering channel with pools in and along nearly 1,700 linear feet of Carli Creek
- 61 large wood habitat structures for fish and other aquatic wildlife
- a backwater channel
- floodplain enhancements through grading, invasive, and non-native species removal, and planting a diversity of native species
- enhanced wetlands and an additional 1.36 acre of wetland
The total project budget including land acquisition is $4 million. WES is supported by key partnerships, such as Portland General Electric (PGE) who awarded WES $380,000 for the stream restoration elements of the project. In addition to the PGE grant, funding for the project comes from surface water fees paid by property owners within the WES service area.
