Documents filed under Washington’s environmental review process reveal a list of projects in the works for the Mid-Columbia.
The State Environmental Policy Act, or SEPA, often provides the first look at the mixed-use projects, mini-storage facilities, apartments, industrial expansions, subdivisions and more that are working their way through the various planning departments of Benton, Franklin and Walla Walla counties.
Here’s a look at projects that appeared in the SEPA register in the past month.
Kennewick
Knutzen Engineering has submitted plans to rezone the 2-acre parcel at 9320 W. Clearwater Ave. from commercial community to commercial general to allow for future development.
Bonneville Power Administration
Bonneville Power Administration is proposing to build a new 18-mile-long 115-kilovolt transmission line and substation between the existing Badger Canyon substation and the existing Ashe-Marion transmission line to the west. A small portion of the new line would be built with steel monopoles in an existing transmission corridor near the Badger Canyon substation, while the rest of the line would be built using wood pole structures. Fiber optic cable would be added to the new line, as well as to other transmission lines in the area, to improve operational communication and control.
The project’s aim is to improve long-term electric reliability, short-term operational flexibility and system maintenance needs. The project would enable BPA to increase the amount of electricity it can deliver to the area. The project is one of four that BPA is proposing in the area, collectively called the Tri-Cities Reinforcement project. When the project is complete, it would increase BPA’s transmission capacity in the area by 66%.
Two route options were evaluated, one following the railroad along East Badger Road and the other following East Badger Lateral canal. BPA will move forward with the railroad route.
