New York City’s Department of Housing Preservation and Development approved plans this week by real estate developer Extell for their new building on 40 Riverside Boulevard. The 33-story tower will have 219 units, 55 of which will be designated for low-income renters. Sounds good all around, but there’s one little quirk in the plan that’s making city residents angry. Because of NYC’s Inclusionary Housing Program, by including low-income apartments in the building Extell can build bigger than is normally allowed–and Extell gets a nice tax break to boot. But the company has drawn fire for its proposal to include two main entrances to the building–one leading to the standard-price units and another–built on “a back alley”–servicing the low-income units.
