Crews Complete Electrical Reliability Work in Tukwila

This past December, a Seattle City Light contractor completed the final repair work on several existing electrical conduits along 42nd Avenue South in Tukwila, WA. The project also included the installation of new vaults to enhance reliability for electrical service.

Contracted crews started this three-month project in late October 2017. City Light thanks the residents of Tukwila for their patience during the successful completion of this project.

Seattle City Light to Repair Conduit on 42nd Avenue South

In late October 2017, a Seattle City Light contractor will be working along 42nd Avenue South in Tukwila, WA to repair existing electrical conduits and install new vaults. This work will enhance the electrical system’s reliability and reduce the likelihood of unplanned power outages.

Contracted crews will be working on the east side of the sidewalk on 42nd Avenue South to complete these repairs, which may cause some noise due to heavy equipment. However, the contractor will adhere to the City of Tukwila’s noise ordinance.

The contractor will require a road closure (with local access) to set the electrical vault with a crane.

Access to most driveways will be maintained at all times. Others, near the work area will have temporary driveways and routed access.

In order for crews to do their work safely, maintenance power outages are required. Contracted crews will notify affected customers at least 24 hours in advance of any outage. The notifications will specify the date, time and duration of the outages.

This project is tentative to start in late October 2017. Construction will last approximately two months. Daily work hours are from Monday to Friday, 7:30 a.m. to 5 p.m., with possible weekend work. Any scheduled weekend work will be coordinated with the City of Tukwila.

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.

Creating Buzz Along City Light’s Creston-Duwamish Transmission Line

Seattle City Light is working with partners to enhance habitat for native pollinators like this bumble bee.

Seattle City Light is working with a host of stakeholder groups to create a lot more buzz along the corridor for the utility’s Creston-Duwamish transmission line, which runs from South Seattle to Tukwila.

The collaboration is aimed at improving habitat in the area for native bees and other pollinators.

City Light is working with The Common Acre, Earth Corps, Veterans Conservation Corps, the City of Tukwila, Forterra and the Friends of Duwamish Hill on the project. Work includes a survey of existing vegetation and pollinators; removal of non-native or invasive plants; and planting native vegetation that supports native pollinators, such as mason bees, bumble bees and butterflies.

“Specifically, we are looking at how pollinator habitat impacts management of tree species and invasive weeds and then how effective are the habitat improvements at increasing the number of bees and butterflies,” City Light Senior Environmental Analyst Rory Denovan said.

Additionally, the utility hopes the native plants will suppress the growth of invasive weeds and trees, reducing the risk that those plants would grow into the transmission lines where they could disrupt service,  Denovan said.

The project started as part of the Enhanced Environmental Leadership Initiative outlined in City Light’s six-year Strategic Plan and is a cooperative effort between City Light’s Vegetation Management unit and Environmental Affairs and Real Estate Division.  “This program builds on the long history of partnerships and habitat expertise that City Light Vegetation Management staff have developed over the years,“ Denovan said.

The utility created a Community Stakeholder Team to identify opportunities for additional environmental engagement. Team member Bob Redmond, who is the executive director of The Common Acre, pitched the idea of improving habitat for pollinators, and the project took flight.

The Common Acre has been working with the Port of Seattle since 2011 on a similar project called “Flight Path” that uses open space near SeaTac International Airport for honeybee hives and habitat restoration with native plants such as goldenrod, big leaf maples and rhododendron, to support native bees.

Seattle City Light is the 10th largest public electric utility in the United States.  It has some of the lowest cost customer rates of any urban utility, providing reliable, renewable and environmentally responsible power to about 750,000 Seattle area residents.  City Light has been greenhouse gas neutral since 2005, the first electric utility in the nation to achieve that distinction.

Power restored in parts of southwest and south service area

Power has been restored to most of Burien, Normandy Park and SeaTac.  Crews are still working to restore an outage in Tukwila that was caused by a construction crew cutting an underground cable.  Crews estimate restoration within the hour.

Earlier, two power outages in Tukwila, Normandy Park, parts of SeaTac and Burien were affecting 9,811 customers.   Restoration on the outage in Tukwila is estimated to be by 2:30 p.m.  Outage information updated at
