The Bonneville Power Administration has created an online map of its proposed high-voltage transmission line running through Southwest Washington.
The agency designed the map using Google maps, and it shows locations of towers and proposed new rights-of-way for the transmission line.
The map is online at http://www.bpa.gov/gis/i5/gmviewer.html. The BPA says it will provide printed copies for anyone without Internet access.
The BPA, the region's largest wholesale power distributor, has proposed building a 70-mile-long line from Castle Rock to Troutdale, Ore. The line could affect as many as 6,000 property owners, mostly Cowlitz and Clark counties. The agency has proposed building substations at the north and south end of the 500-kilovolt line.
The BPA plans to develop a final map of possible routes in 2012. If the agency moves forward with the plan, which would cost between $340 million and $360 million, a new line could go online in 2015.
