Draft Supplement to the Environmental Statement Fiscal Year 1975 Proposed Program : Facility Location Supplement for Maple Valley 500-kV Reinforcement Study Area 75-14.

Technical Report ·
OSTI ID:5558855
The proposed plan of service consists of the construction of approximately 16 miles of double-circuit 5000kV transmission line. Of this total length 2.5 miles will require new right-of-way easement, 8.25 miles would parallel existing transmission lines, and 7.25 would occur on existing right-of-way. In addition, a new substation will also be required southwest of Snoqualmie, Washington. Construction of the proposed 16-mile transmission line would require approximately 134 acres of new right-of-way easement. About 6.5 miles of the line's length would traverse forested land resulting in the removal of about 105 acres from the production of timber. Construction of the new Snoqualmie Substation would require about 25 acres of land and depending upon the actual site selected would remove from 20 to 25 acres of forest land from production. Also expected to occur is the disturbance of game in the immediate vicinity of the facilities during construction, some soil erosion primarily during and immediately after construction, siltation in nearby streams, disturbance of nearby residents from noise and dust during construction, and some degradation of AM reception immediately adjacent to the right-of-way. 16 figs.
