Location:      The project is a corridor project which begins at the Bonneville Power Administration substation in Alvey, located south of Eugene, Lane County, extends south to Reston in Douglas County, and west to Fairview, Coos County, Oregon.  The site begins in Section 14, of Township 18 South, Range 3 West and continues through Section 24 of Township 27 South, Range 12 West.

 

Waterway:    Through the project corridor there are over 680 identified wetlands and waterways.

Project Description:  The project entails replacing aged wood pole structures and associated structural components on the existing 230-kV Alvey-Fairview transmission line and upgrading roads to facilitate construction and year-round access for maintenance. Project activities that may result in impacts to waters and wetlands include removal and replacement of wood pole transmission line structures, access road upgrades, including upgrading existing roads, developing new roads, maintenance or replacement of culverts, and installation of dip drains.  Overall there will be a total of 5.61 acres of temporary impacts and 7.16 acres of permanent impacts combined in the Coast Fork Willamette River watershed, South Umpqua watershed, Umpqua watershed, and the Coquille River watershed.

 

Of the 709 transmission pole structures that would be replaced with this project, 87 are located within wetlands, including 18 three-pole structures and 69 two-pole structures.  Permanent impacts to wetlands would consist of excavation of a 5-foot diameter hole at each pole location to a depth of 10 to 12 feet.  A 4-foot diameter corrugated metal pipe footing (e.g., culvert) will be installed upright in the hole extending to the soil surface.  The new pole will be placed within the vertical pipe and will be backfilled with gravel or crushed rock.  The use of culverts surrounding the poles improves the stability of the pole in soft wetland soils and increases the longevity of the pole by due to backfill with aggregate (3/4-inch crushed rock).

 

Improving roads involves minor adjustments to existing roadways or driveways to correct light rutting, adjust cross slope for drainage, and apply additional surfacing material as needed to support construction and future maintenance.  Road improvement would consist of light grading and application of 3 inch of 1 ½ inch minus gravel material and should result in an increase in road width of less than 2 feet.  All Improve Road work would have less than a 20 percent increase in road width.  About 34.7 miles of existing access roads or driveways would have road improvements associated with the project.

 

Reconstruction of roads involves rough grading to adjust existing roadway grades, increase roadway width, smooth out depressions, adjust the cross slope for drainage followed by application of base material and surfacing. For road reconstruction, grading may be done in the top 4 inches of the existing road surface and fill for road reconstruction would include addition of 5 inches of 1 1/2 inch minus gravel to the final graded surface.  About 57.6 miles of existing access roads are proposed for reconstruction.  Roadways for reconstruction may need to be widened by more than 2 feet, are partially covered with vegetation or debris, or require substantial work within the road prism to return the roadway to a usable condition.  Subgrade stabilization, which would include slightly deeper excavation and fill of coarse rock, may be required if soft subgrade conditions exist or as determined by the contractor.

 

Road construction involves excavation of the existing ground surface and the import of rock to develop a solid subbase and road surface.  The road bed would be constructed with excavation of approximately 0.5 to 1 foot of soil that would be considered removal of fill from wetlands where the alignment crosses wetlands. The road bed would be constructed with 5 inches of crushed 3 inch minus rock with a minimum of 3 inches of 1 1/2 inch minus gravel on the travel surface. Where soft soil conditions dictate the need for subgrade stabilization, 1 foot of native soil would be excavated from the road alignment, followed by the placement of 1 foot of quarry spalls wrapped in geotextile fabric, which is then overlain by 5 inches of compacted road surfacing material.  About 6.5 miles of new permanent road would need to be constructed to allow complete access to the alignment for transmission structure replacement.

 

Temporary roadways built during construction to access the transmission facility in locations where permanent roadways will not be constructed.  A temporary road may be necessary to address topography, soil conditions, seasonal site conditions, safety concerns, or other site conditions encountered during construction.  These roads will be fully removed after project completion and the site will be restored after the road is no longer needed for construction.  The temporary fill materials could include timbers, ground mats, or gravel over geotextile fabric.  All fill would be removed after rebuild construction. Areas would be returned to pre-construction contours and seeded with a native seed mix or seed mix requested by the landowner.  To minimize cost and site disturbance, temporary roads are installed to minimum machine access standards (as narrow as practicable).  Approximately 1.28 miles of temporary access road are proposed along the 98-mile transmission line corridor.

 

A total of 84 culvert replacements are proposed which includes 14 upgrades to culverts designed for fish passage and 70 replacement culverts. Five new 18-inch diameter culverts would be installed.  Seven bridges would be installed including three new bridges to replace the existing culverts.  Four existing bridges in disrepair would be replaced within their existing footprints.

 

Temporary staging areas may be selected by the contractor for use during construction along or near the transmission line easement to stockpile structure materials and construction equipment.

 

Mitigation: The applicant has proposed purchasing credits from Coyote Prairie North Mitigation Bank, Cow Hollow Mitigation Bank, and Umpqua Interior Foothills in-lieu fee project as compensatory wetland mitigation for permanent impacts of the project.

If a permit is issued, the Corps will determine what is appropriate and practicable compensatory mitigation.  The amount of compensatory mitigation required shall be commensurate with the anticipated impacts of the project.

Purpose:  The project purpose is to maintain the existing utility lines and to maintain/upgrade access roads.

 

Drawing(s):  Thirty (30) drawings are attached and labeled Corps No. NWP-2013-240

Endangered Species:  Preliminary determinations indicate that the described activity may affect an endangered or threatened species or its critical habitat.  Consultation under Section 7 of the Endangered Species Act of 1973 (87 Stat. 844) has been initiated by the Bonneville Power Administration.  A permit for the proposed activity will not be issued until the consultation process is completed.

 

Cultural Resources:  An initial evaluation of the proposed project area indicates the described activity is not located on property registered or eligible for registration in the latest published version of the National Register of Historic Places.  The Bonneville Power Administration is completing a cultural Resources inventory and is coordinating the findings with the State Historic Preservation Office.

 

This notice has been provided to the State Historic Preservation Office (SHPO), interested Native American Indian Tribes, and other interested parties.  If you have information pertaining to cultural resources within the permit area, please provide this information to the Corps’ project manager (identified on page 1 of this notice) to assist in a complete evaluation of potential effects.
