Thornton Creek/Jackson Park Erosion Control and Water Quality Monitoring

Client: City of Seattle Location: King County (Seattle), WA Contact us for more information.

Project Background & Challenges

The Thornton Creek/Jackson Park project involved constructing three off-line detention ponds to reduce downstream flooding and to realign and restore 2,300 feet of Thornton Creek. This sensitive urban stream is not only Seattle’s largest watershed but also home to five salmonid species. Protecting water quality was a major concern during construction.

Solution

Aspect deployed a team of engineers and certified erosion-control (ESC) inspectors for this project. These professionals worked with the City and its contractor to develop and implement a temporary plan for controlling erosion. We also provided third-party ESC inspection services and monitored water quality throughout the life of the project. Because of our strong working relationship with the contractor and City, the team successfully protected water quality while meeting all project goals.
