Bethlehem council not on board with Martin Tower changes without more details on redevelopment Updated 6:00 AM; Facebook Share Members of Bethlehem City Council want more detail on the redevelopment of the 53-acre Martin Tower site before granting zoning changes that could allow for a more suburban project. Council held a public hearing Tuesday night on the developer’s request to weak the zoning rules governing the redevelopment of the former Bethlehem Steel Corp. world headquarters to allow for more parking near proposed medical buildings, the addition of a new Eighth Avenue entrance and a slightly denser development. Council took no action on the request Tuesday, but spent more than an hour peppering the developer representative, Duane Wagner, and the city administration with questions about the proposal and how the project fits into the city’s goals of a more sustainable, walkable and equitable community with green spaces for residents.
