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.

Jackrabbit Lane subdivision

Richland

Permit Surveying Inc. submitted plans to divide 20 acres of commercial property at 225 Jackrabbit Lane into four lots and build a private road with utilities to service each lot.

Webber Canyon substation

BPA

Bonneville Power Administration has proposed building a new Webber Canyon substation next to the existing Ashe-Marion 500-kV line. It would connect to BPA’s existing Badger Canyon Substation with a new 18-mile-long 115-kV transmission line.

In the existing transmission corridor near Badger Canyon Substation, the new line would be built with steel monopoles, and wood poles would be used elsewhere. Fiber-optic cable also would be added to the new line, as well as existing transmission lines in the area, to improve operational communication and control. To incorporate the new transmission line, Badger Canyon Substation would be reconfigured and upgraded.

Proposed locations run near West Clearwater Avenue in Kennewick, along East Reata Road, East Badger Road and East Badger Canyon Road, then south of County Well Road.

The goals of this project are to improve long-term electric reliability, improve short-term operational flexibility and address system maintenance needs to support the Tri-Cities area’s increasing demand for power.
