Natural Drainage Systems (NDS) Designs
This project consists of designing and constructing a natural drainage system at four locations in Northeast Seattle. The project goals are to improve Thornton Creek water quality and decrease the chance of flooding downstream.
The South Thornton Natural Drainage System (NDS) Project has completed final design, and we are now presenting updated street and drainage improvements to the community.
We’re partnering with the Seattle Department of Transportation (SDOT) to incorporate sidewalks into the streets that do not currently have formalized sidewalks, which aligns with community requests to install sidewalks as a part of this project.
