Line Reconductor Project Narrative
Shoreline Exemption
Project name, size, and location of site
PSE Talbot-PACCAR 115 kV Transmission Line
Work within the shoreline environment is located within the City’s Cedar River Park at 1715
Maple Valley Hwy (parcel #s 1723059013 and 1723059015).
Brief description of proposed work
Puget Sound Energy (PSE) is proposing repair and maintenance activities on approximately 1.5
miles of existing 115 kV transmission line within the City of Renton. This will include selective
wood pole replacement and pole reframing, as well as replacement of the existing conductor.
The existing transmission corridor crosses through the Cedar River shoreline environment (200
feet from the ordinary high water mark (OHWM)). Work proposed within 200 feet of the
OHWM associated with the transmission project includes the replacement of 3 existing wood
poles and the 115 kV conductor that crosses over the Cedar River. See Project Description on
Page 1 of the project Stream Study.
Basis for exemption request
The basis for the exemption request is that PSE will be performing repair and maintenance
work within 200 feet of the Cedar River OHWM. This work fall under RMC 4-9-190C(3):
Maintenance and Repair: Normal maintenance or repair of existing structures or developments,
including damage by accident, fire or elements. Replacement is the normal method of repair
for transmission line infrastructure, including poles and conductor.
Anticipated dates of work
September – October 2018
Other permits required for proposed project
None within shoreline. Critical Areas exemption elsewhere along corridor.

Current and proposed use of site
Transmission line corridor within City park.
Special site features (i.e. wetlands, water bodies, steep slopes)
Cedar River
Statement addressing soil type and drainage conditions
See Geomorphic (Soil) Indicators discussion on Page 3 of the project Stream Study.
Total estimated construction cost and estimated fair market value of the proposed project
$375,000 (within shoreline jurisdiction)
Estimated quantities and type of materials involved if any fill or excavation is proposed
Net excavation will be minimal. Pole holes will be augered or excavated with a vac truck.
Estimated excavation for 3 poles will be approximately 40 cubic yards per pole (120 cubic
yards). Excavated soil will be used to backfill holes where existing poles are removed.
Number, type and size of any trees to be removed
No tree removal is proposed.
Distance from closest area of work to the Ordinary High Water Mark of the shoreline
The closest pole to be replaced is approximately 70 feet from the OHWM.
Nature of existing shoreline (e.g. high bank, naturalize, rip rap, bulkhead, etc.)
See Field Investigation discussion on Page 2 of project Stream Study.
If the proposed project exceeds a height of 35-feet above the average grade level, discuss the
approximate location of and number of residential units, existing and potential, that will have
an obstructed view
No residential units or other regulated structures are included with this project.
