A rendering of the green space planned next to the proposed 26-story office tower. The Pittsburgh Penguins and their development partners aim to break ground on a 26-story office tower on the Lower Hill this summer. Many stakeholders are eager to see investment, but want to ensure investment benefits the neighborhood as a whole. At a meeting Monday night, residents noted that while the developers have made numerous reinvestment promises, the specifics remain unclear, and therefore, unenforceable. As she began the meeting, Hill Community Development Corporation CEO Marimba Milliones said she’s more eager than anyone to see development. “But we have to make sure we do it in a way that does not wash away the residents of our community, that does not sweep away the culture of our neighborhood,” she said.
