Welcome to the Denny Substation Project page, your portal to information about Seattle City Light's design and construction of a new electrical substation, power distribution network and transmission line to serve our growing city.

Summer 2015: What's been happening?

We're getting close to completing final design of the substation (see Denny Substation slideshow for more info) and will be seeking final approval to move ahead with construction. Approval involves several steps, including a public hearing and several City Council meetings:

The City Council's Transportation Committee will hold a public hearing on two topics related to the Denny Substation Project.

Street Vacation

Oral comments will be taken on the petition by Seattle City Light to vacate (to acquire the public right-of-way) Pontius Avenue North between Denny Way and John Street in the South Lake Union Urban Center area of Seattle. The vacation is proposed to support the development of the Denny Substation.

Land Use

Oral comments will be taken on the Master Use Permit, which would allow for the construction of the Denny Substation in a Seattle Mixed Use Zone.

When: July 30, 2015
5:30 PM

Where: Belltown Community Center
415 Bell St.

Written comments must be submitted by 4:30 PM, July 30, 2015. They can be sent to:

Councilmember Tom Rasmussen
Legislative Department
600 Fourth Avenue, Floor 2
PO Box 34025
Seattle, WA 98124-4025
or by email to: Tom.Rasmussen@Seattle.gov

The Seattle City Council will hold a number of meetings prior to giving final approval. A special meeting of the Transportation Committee has been scheduled for August 13th at 9:30 AM, with a possible Full Council vote on August 17th. These meetings, held in Council Chambers at City 2 Hall, are open to the public and include opportunities for public comment. As these meetings are subject to change, please check the Denny Substation calendar for dates and times.
