City Light Sponsors Volunteer Events

Last Saturday, April 16, City Light’s Vegetation Management Unit and Environmental Affairs and Real Estate Division sponsored five Duwamish Alive volunteer events on City Light property to improve the watershed. Here’s a rundown:

Duwamish Hill

Volunteers from Seattle City Light at Duwamish Hill.

A City Light volunteer work-team made up of employees, friends, and family participated in the annual celebration. Enjoying great weather, they worked at the Duwamish Hill Preserve, laying the foundation for a future plant-nursery that will provide healthy vegetation for use throughout the watershed. This site is co-sponsored by Friends of the Hill, Forterra and the City of Tukwila.

Delridge Wetland
City Light partnered with the Delridge Neighborhood Development Association (DNDA) to start work on their dream of transforming the former substation into a community garden and restored wetland.  In partnership with Seattle Parks, DNDA is raising funds to purchase the property. The project’s goal is to provide a place for kids to learn math and science through wetland restoration. Please see story in the West Seattle Blog.

Duwamish Substation
City Light has partnered with EarthCorps to enhance habitat along the Duwamish River at City Light’s Duwamish Substation.

Hamm Creek
With the leadership of City Light’s Plant Ecologist Marie Swanson, the Veterans Conservation Corps has continued their longtime stewardship of Hamm Creek to honor the legacy of activist and Vietnam vet, John Beal.

Bangor Street
City Light has partnered with The Common Acre to engage the community and enhance pollinator habitat as part of City Light’s Creston-Duwamish green transmission line.

Neighbors at this south Seattle site have responded positively to the opportunity to transform this “weedy” area into a better habitat for pollinators and asset for the community. The Common Acre has been studying diversity of bees and other pollinators on the Creston-Duwamish transmission line.

City Light Completes Cedar Falls Siren Testing

Mobile siren for Cedar Falls sound test

Seattle City Light staff tested various audible warning sirens near the Cedar Falls Masonry Dam on Wednesday, March 2. Staff picked four test areas and were stationed at nearly 10 sites for sound-level measurements.

The utility will be installing three new warning sirens later this year around the Cedar Falls Powerhouse, Rattlesnake Lake and the Masonry Dam.

The purpose of the siren system is to provide an emergency warning in the event of a dam failure. To learn more about the project, please visit

As of 4 pm, City Light crews are making some progress toward getting power back on, down to 48,700 customers out from a high of more than 58,000.

Please be very cautious if you’re out and about and stay clear of any downed power lines.

Update on windstorm outages

Seattle City Light continues to see more outages from the wind, now up to at least 35,000 customers.

The utility prepared for this and has extra crews out in the field to spot problems and get them fixed as quickly and safely as possible.
