I have removed the "power=pole" tag and corrected "utility=power" to "utility=street_lighting" on this streetlight in Changeset: 158191611.

Additionally, I have updated my process for adding these Seattle City Light poles to ensure that the "power=pole" and "utility=power" tags are not added by default, to minimize the chance of similar errors being introduced in the future.

Thanks! Closing note.
