I guess the logic goes something like this: it's already developed and therefore aesthetically compromised, so more development in the form of overhead power lines won't matter to people who live in the Milwaukee area. Or, to be more precise, in Wauwatosa, near Underwood Parkway and the Milwaukee County Grounds.
According to an article in yesterday's Journal Sentinel, "'Selecting another route would shift millions of dollars of extra costs
for underground lines to ratepayers in the ATC footprint far removed
from the Milwaukee area, who would not benefit from a more aesthetically
pleasing project area,' the commission's decision says."
The short-sighted decision by the Public Service Commission disturbed many in the region who have worked very hard to support alternative routes.
The City of Wauwatosa is one of the stakeholders considering what further options, including the possibility of legal action, may be used to challenge this decision. (May the odds be ever in their favor!)
If you go to the article in the Journal Sentinel you will see a map that isn't completely accurate. I learned today at a meeting for County Grounds stakeholders that the section shown crossing the County Grounds will actually turn at Hwy 45 and run south to Watertown Plank Rd. where it will follow the dashed line to the substation. The correct map is below.
