They're going to build a covered reservoir in Washington Park, and in order to do that, they plan to take out over 200 trees, many of which are at least 120 years old. How Green&Sustainable™ can you get? They say they'll re-plant, but it'll be decades before the park bears any resemblance to what it is today. As engineers say, "When in doubt, take it out."
I almost never agree with perennial gadfly Bobby Salinger, who makes his bank over at Portland Audubon, but on this one he's right: that level of tree loss is going to be a disaster, and not just for park visitors, but for local wildlife. The city may have a fight on its hands over this one; they claim that they have to do it because the feds told them to, but like New York City, we've had open-air reservoirs for a century with no health issues. Chuckie Schumer got an exemption for NYC, but Oregon politicians just caved.
This is going to be bad.
