Earlier today, we noted that an activist group is stepping up its ongoing war on City Council member Margaret Chin over the Seward Park Mixed-Use Development Plan. Last week, Chin urged Community Board 3’s land use committee to vote “yes” on the city’s framework for the 1.65 million square foot project. She acknowledged the community board’s reservations about the proposal due to a 60-year term on the affordable housing units. Chin and her colleague, Council member Rosie Mendez, vowed to fight for permanent affordability.
