Carli Creek Water Quality Project

A Creek Runs Through It

Watch on YouTube

The Carli Creek project is a 15-acre water quality facility along the Clackamas River. When completed, this project will reduce surface water pollutants originating from the surrounding industrial area.

Location

The problem

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:

The solution

The project will include the construction of channels, ponds, wetlands, and permeable berms to treat stormwater, filtering pollutants before the runoff enters the Clackamas River.

The project will also include erosion control and habitat structures for the benefit of fish and aquatic wildlife.
