PG&E's Project

PG&E owns three 115 kV double-circuit power lines on steel open lattice towers within a single, 160-foot wide right of way that crosses the Montanera Project, a proposed residential community located in Gateway Valley, south of Highway 24 in the City of Orinda (Contra Costa County). Developer Orinda Gateway, LLC has asked PG&E to relocate approximately 1.1 miles of the three lines, which will require PG&E to construct approximately 1.61 miles of lines on a new route. The current facilities to be relocated include the Sobrante-Grizzly-

Claremont #1 and #2 115 kV Lines (both double-circuit lines), and the Moraga-Claremont #1 and #2 115 KV Lines (two single-circuit lines making up a double-circuit line). These lines run generally east from Claremont substation in Oakland to where they join a north-south route located to the east of the Montanera Project site in Orinda before connecting to PG&E's Moraga Substation. The easternmost 1.1 mile segment crossing the Montanera Project will be relocated. The relocated lines would extend approximately 1.61 miles from a location west of Orinda off Highway 24 near Gateway Exit and Upton Road to a location southeast of Orinda near the PG&E Moraga Substation. The relocated lines are expected to include approximately nine to ten lattice steel towers each (for a total of approximately 30 structures) with a typical height of 90 to 125 feet, and typical span lengths of approximately 450 feet to 1,500 feet. The relocated lines, like the existing power lines, would be aligned parallel as much as possible, with towers grouped together in sets of three to minimize visual impact, habitat impacts, and soil disturbances. PG&E provides a more complete description of the relocated lines in the application and accompanying exhibits.
