Herrera Celebrates Milestone in Broadview Natural Drainage System Project with Seattle Public Utilities

Author: Neil Schaner, PE

Herrera is proud to announce the successful completion of the design phase for the Broadview Natural Drainage System (NDS) project in partnership with Seattle Public Utilities (SPU) and project partners Brown and Caldwell and Osborn Consulting, marking a significant step in the city’s ongoing efforts to remove pollutants from stormwater draining to salmon-bearing streams.

The Broadview NDS project, which will involve the installation of several bioretention facilities along NW 127th and NW 130th Streets, is set to treat runoff from approximately 19 acres of right-of-way and adjacent residential area. The facilities will play a crucial role in improving the quality of stormwater before it flows into West Mohlendorph and Pipers Creeks, key water bodies that will benefit from the enhanced stormwater treatment.

Neil Schaner, PE, Herrera’s project engineer, shared his excitement as the design phase wrapped up. “This project has evolved over time and faced its challenges, but we are not only proud of the design, we’ve gained invaluable experience that will benefit future projects. We’re all looking forward to seeing the design come to life during construction.”

The Broadview NDS project is part of a broader effort by SPU to integrate Green Stormwater Infrastructure (GSI) in Seattle. It draws on lessons learned from other successful NDS projects and in turn is informing the design of other city-wide capital projects, including the North Thornton NDS and Pipers NDS projects. As these projects continue to shape the future of stormwater management in Seattle, the Broadview NDS project will not only continue to treat stormwater entering West Mohlendorph and Pipers Creeks but will also contribute to a growing body of knowledge that helps improve the city’s infrastructure and ecological health.
