Check out the new environmentally friendly light poles Seattle City Light is using.
Crews use a special machine, built by workers in Seattle City Light's machine shop at the South Service Center, to shrink wrap the ends of the pole. This stops chemicals from leaching out of the treated poles into the ground, and has the added bonus of doubling the life of the poles, saving rate-payers money.
City light is the first utility to try the new technology.
Experts say the technology is especially good for salmon in local creeks. The utility plans to use the poles in environmentally sensitive areas first because of the listing of local salmon under the Endangered Species Act.
