As the Pittsburgh City Council is nearing a vote on whether to start collecting a parks tax that voters approved by referendum last year, City Controller Michael Lamb said the city has no choice but to start collecting the tax. "At this point, I think council has got to move forward with this and I think they are legally required to move forward with this," Lamb said. "I don't think there is too much wiggle room in getting out of it given the wording of the referendum." PublicSource reported last month that at least two city councilors preferred not to collect the tax at all. But Lamb said at a press conference Thursday that his understanding is that the council will vote to start collecting the tax in 2021.
