2017 project updates

 

Center City Connector Streetcar-related natural gas projects
  • In advance of construction of SDOT’s Center City Connector Streetcar project, PSE is working to relocate segments of natural gas pipeline in downtown Seattle. 
  • In 2017, crews worked along 1st Ave S to prepare for the Center City Connector Streetcar project. The second phase of PSE's relocation work will resume in early  2018.
  • In 2017, work included:
    • Relocation of natural gas main along 1st Ave S just north of S Jackson St  and along S Jackson St between 1st Ave S and Occidental Ave S, including construction and hard surface restoration.
    • Service of an existing vault on 1st Ave S between S Washington St and Yesler Way. The vault lowers natural gas pressure to where we can deliver it safely to our customers.
  • We will continue to work diligently to minimize impacts to neighbors, the environment, and traffic during construction.
  • To receive weekly construction and traffic updates when construction is active, sign up for our Center City Connector Streetcar email list.

12-inch pipeline relocation project

  • PSE completed the installation of Phase 1 of the pipeline relocation project in September 2013. Phase 2 was completed in February 2016. We appreciate residents and businesses in the project area for their patience and understanding during this work.
  • Phase 3 will begin shortly after the Viaduct is demolished. We will relocate a segment of 12-inch pipeline from Pike Street going north to Elliott Avenue.
 

Project Overview

Center City Connector Streetcar

View project map

In conjunction with Seattle Department of Transportation’s (SDOT) Center City Connector Streetcar project, Puget Sound Energy is working to relocate, reconfigure, and protect segments of natural gas pipeline in downtown Seattle. This work will be done in coordination with other utility relocation work in advance of Center City Connector Streetcar construction. PSE is working closely and proactively with SDOT and other jurisdictions and agencies to ensure the continued safety and reliability of our existing natural gas system in the area.

This project is required to accommodate Center City Connector Streetcar construction. For more information about this project, read the project fact sheet or visit SDOT’s project website.
 
Construction
We will work diligently to minimize impacts to neighbors, the environment, and traffic during construction.
  • While construction is taking place, there will be some temporary traffic impacts, such as lane closures and limited access to on-street parking. It’s our goal to minimize the impact of construction on local traffic and parking.
  • Some night work may be required. If necessary, PSE will follow all applicable city requirements regarding acceptable noise levels at night.
  • Some work may require a temporary disruption in service to natural gas customers. If a natural gas outage is necessary, a PSE representative will coordinate directly with affected customers.
2017 work includes:
  • Relocation of intermediate pressure (IP) natural gas line along S Jackson St between 1st Ave S and 2nd Ave S (completed in July 2017)
  • Relocation of intermediate pressure (IP) natural gas line along 1st Ave between Madison St and Yesler Way and along 1st Ave S between S Washington St and S Jackson St (starting in October 2017)
  • Replacement and relocation of three service regulators along 1st Ave S between Columbia St and S Main St (expected in fall 2017)
Additional sections of natural gas pipeline along 1st Ave between Stewart St and Seneca St will need to be relocated in 2018. More details about this work will be shared closer to construction in 2018.
 

Alaskan Way Viaduct

In conjunction with Washington State Department of Transportation's (WSDOT) Alaskan Way Viaduct Replacement Program and several other Seattle-area transportation projects, Puget Sound Energy is working to relocate, reconfigure and protect segments of natural gas pipeline in areas of downtown Seattle to ensure continued public safety and customer reliability.

The Alaskan Way Viaduct Replacement Program, Waterfront Seattle and Seawall Project are collectively the largest set of associated projects to take place in the Puget Sound region in several decades. Additionally, there are multiple other Seattle-area transportation projects planned to take place over the next several years; many of these projects require relocation of utilities, including PSE's natural gas system. These projects are driven by the City of Seattle, Sound Transit, Washington State Department of Transportation, the Port of Seattle and the U.S. Army Corps of Engineers.

PSE is working closely and proactively with all the jurisdictions and agencies to ensure the continued safety and reliability of our existing natural gas system in the area.
