Saving Salmon at the Center of the Universe

The long wait has ended and the new Data 1 Building is open for business and already actively saving salmon! Our Salmon-Safe Puget Sound team is delighted to be working with COU LLC, Owners JoAnna Callahan, Mark Grey and Mark Hess at this beautiful new building located at the corner of 34th Ave North and Troll Avenue in the heart of Fremont, also known as the Center of the Universe. In this case, we might think of the building at the center of salmon migration.

Cascading bioswales at the Data 1 site serve as an inviting green landscape amenity & are mitigating toxic runoff from the Aurora Bridge.

A new home to Tableau, designed by Weber Thompson and engineered by KPFF, this Salmon-Safe certified project has garnered lots of attention for its work and data outside the building. Inspired by a story about polluted runoff from the 520 Bridge, the owners set about to create a project that provides public benefit in the right-of-way with cascading bioswales and rains gardens treating polluted runoff from the Aurora Bridge. Stormwater not retained by these features will be captured in an underground vault prior to being discharged via a dedicated storm sewer to Lake Union.

During design phases of the project, the owners discovered that polluted runoff from the Aurora Bridge flowed directly into Lake Union and the ship canal which is an important migration route for salmon. The outfall of polluted water directly impacts the Chinook, Sockeye, Coho and Steelhead that pass through this narrow corridor on their way to the North Lake Washington and Sammamish watersheds.

The project has received Salmon-Safe certification because its overall practices are beneficial to salmon, including reaching beyond its own site boundaries to mitigate a major neighborhood water pollution source. Additional green stromwater infrastructure facilities are being planned on other properties in the vicinity to treat more of the bridge surface runoff. To form a baseline of the highway runoff water quality prior to the installation of treatment, samples of the flow from the bridge were collected on five occasions during February-April 2017. The intention is to monitor discharges from the eventual treatment facilities for comparison with this baseline. It serves as an excellent model project for private landowners to go beyond what’s required and standard operating practices to ensure untreated stormwater mitigation on private lands. Look for this beautiful building and Salmon-Safe interpretive signage celebrating their water story on your next trip to Fremont.

Stay tuned also for more good news for Fremont coming from Salmon-Safe, Stewardship Partners, the COU LLC team and other community partners. This project is a perfect example of the collaborative partnership model that is the hallmark of Stewardship Partners’ programs and projects. By working together, we can create structures and systems that are so much more than a traditional office building.
