Thurston County tree wire projects


Winter 2012-13 project updates
  • Construction in Rainier along Rainier Road and Military Rd SE started in June 2012 and was completed in September 2012.
  • We started construction on the Panorama City project in late August 2012 and completed the work in September 2012.
  • Work in Tenino along Crowder Road started in mid September 2012 and was completed in December 2012.
  • Work along Littlerock Rd SW and 133rd Avenue SW in Littlerock started in late-September 2012 and is expected to be completed in December 2012.
  • Work in the Madrona Beach area of Olympia started in early October 2012 and is expected to be completed in January 2013.
  • We began work in the Thompson Place area in early November 2012 and expect to be completed in late December 2012.
  • We expect to begin work in Tumwater along Eskridge Blvd in late December 2012 and expect to be completed in January 2013.
Project overview

As part of Puget Sound Energy’s work to improve the reliability of the energy we supply to communities throughout Thurston County, we have identified several neighborhoods in Thurston County that have historically experienced a high number of tree-related power outages. To decrease the number of tree-related outages in these areas, we plan to replace portions of the existing local distribution power lines with tree wire. Tree wire has a special coating that prevents a power outage in the event a tree branch comes in contact with the line. By installing tree wire in other locations in our service area, we have helped reduce power outages related to falling tree branches by 70 percent. Once the work is completed, customers served by these power lines will see improved electric service reliability.

2012 Projects
  • Rainier (Rainier Road and Military Rd SE):
    • We installed approximately 3 miles of tree wire along Rainier Rd between Military Rd SE and 133rd Ave SE and along Military Rd SE between Rainier Rd SE and McIntosh Ln SE.
    • This project was completed in mid-September 2012.
  • Lacey (Panorama City):
    • We expect to reduce tree- and limb-related outages near Panorama City by replacing nearly 4,500 ft of existing distribution wire with tree wire along Golf Club Rd SE.
    • This project started in late August 2012 and was completed in September 2012.
  • Tenino (Crowder Road SE):
    • We installed approximately 2.2 miles of tree wire along Crowder Road between Old Hwy 99 SE and 184th Ave SE.
    • This project was completed in December 2012.
  • Littlerock (Littlerock Road and 133rd Avenue SW):
    • We plan to install tree wire along Littlerock Road SW and 133rd Avenue SW. Additionally, we will be undergrounding a segment of line along 133rd Avenue SW between Littlerock Road and Erskine Road, and removing an existing segment of line running cross-country from 128th Ave SW to 133rd Ave SW.
    • This project is expected to be completed in December 2012.
  • Olympia (Steamboat Island Rd and Madrona Beach Rd NW):
    • We are replacing approximately 2.8 miles of tree wire along Madrona Beach Road NW and Steamboat Island Rd between 41st Ave NW to Mud Bay.
    • This project is currently in construction.
  • Lacey (Thompson Place):
    • We plan to install approximately 12,600 ft of tree wire north of Martin Way E in the Thompson Place neighborhood.
    • Construction began in early November 2012 and is expected to be completed in late December 2012.
  • Tumwater (Eskridge Blvd SE):
    • We plan to install 1.2 miles of tree wire along Eskridge Blvd SE in Tumwater.
    • This project is currently in construction.
2013 Projects
  • North Olympia (Friendly Grove):
    • We will install 3.8 miles of tree wire in the Friendly Grove area along 81st Ave NE and Zangle Rd NE.
    • This project will be completed in phases, with Phase 1 (81st Ave NE) scheduled for construction in 2013 and Phase 2 (Zangle Rd NE) in 2014.
  • North Olympia (Luhr Beach):
    • We expect to install two miles of tree wire in the Luhr beach area between Hilton Rd NE and Marvin Rd NE.
    • Construction in this area is scheduled to begin in 2013.
  • South Olympia (Fir Tree Rd SE):
    • We plan to install approximately 8,000 feet of tree wire along Fir Tree Rd SE.
    • This project is scheduled for construction in 2013.
  • Olympia (South Bay Rd NE):
    • We expect to install 9,500 feet of tree wire along South Bay Rd NE between Springer Road and Martin Way E.
    • Construction is expected to begin in 2013.
  • Rochester (James Rd and Albany St):
    • We expect to install 3 miles of tree wire along James Rd between Denmark St and Albany St and along Albany St between James Rd and Hwy 12.
    • We expect to begin construction in 2013.
  • Rochester (Applegate St SW and 176th Ave SW):
    • We expect to install 1 mile of tree wire along Applegate St SW between 183rd Ave SW and 173rd Ave SW, and along 176th Ave. SW between Applegate St SW and Pendleton St.
    • We expect to begin construction in 2013.
    What is a distribution line?

    Distribution lines are critical links in the electrical system moving power from electrical substations through distribution transformers directly to homes or businesses. Unlike transmission lines, distribution lines typically carry less than 55 kV; PSE's distribution lines are typically 12.5 kV. Distribution lines can be installed both above and below ground.

    What is tree wire?

    Tree wire is a specially coated overhead wire, which prevents an electric short in the line (and subsequent outage) in the event a tree limb falls into a line. Tree wire is very useful at preventing outages in areas with many trees. Although it does not prevent outages caused by an entire tree falling into a line (if the tree is heavy enough to cause poles and wires to break,) it can significantly lower the frequency of power outages in your community.

    Committed to keeping you informed

    PSE will continue to provide updates to the community. We will notify residents and businesses near the project area when construction will occur. We aim to complete the work with as little disruption as possible.
