Natural Drainage Systems (NDS) and Pedestrian Improvement Designs
60% Design Phase
This project consists of designing and constructing a natural drainage system at three locations in the Delridge and Westwood neighborhoods. The project goals are to improve Longfellow Creek water quality, decrease the chance of flooding downstream, and improve pedestrian safety.
The Longfellow Creek Natural Drainage System (NDS) Project has completed the 60% Design Phase. At the 90% Design Phase, we present updated final design options to community members, answer questions, and finalize the design with NDS features that maximize community satisfaction and meet local traffic, regulatory, and ecosystem requirements.
