Howard Slatkin, the director of sustainability for the New York City Department of City Planning, was a frequent visitor to NYC while growing up in New Jersey, but it was not until he moved to the City after studying history at Brown University, that he became interested in architecture and the social life of places. He earned a master’s degree in urban planning at Columbia University in 2000. At that time the concept of sustainability, though embedded in the course curriculum, had not yet gained the notoriety it has today.

From City planning to City sustainability. Slatkin joined the Department of City Planning immediately after graduation in the summer of 2000; he started as the community planner for Brooklyn Community District 1. His first task was to look closely at the Williamsburg, Brooklyn area and how the community was changing around the L subway line. His work eventually became part of the 2005 Greenpoint-Williamsburg Rezoning. The rezoning addressed population growth in the area and the disparity between the actual and legal uses of industrial buildings that were increasingly being used as residential and commercial spaces. The experience exposed Slatkin to many important issues including mixed-use development, waterfront redevelopment, and affordable housing, which became one of Slatkin’s areas of expertise and focus. The Greenpoint-Williamsburg Rezoning created the City’s current tool for affordable housing development – the Inclusionary Housing Program, which allows developers to take advantage of a floor area bonus in exchange for creating or preserving units of affordable housing for targeted income levels. The program has been used to encourage affordable housing development in many of City Planning’s rezoned areas, including Hudson Yards, West Chelsea/High Line, and West Harlem. From there, Slatkin became increasingly involved with the policy side of city planning and eventually became deputy director of strategic planning, where he oversaw the special projects, and in particular the green initiatives, for all of City Planning’s divisions.

The City Council has approved Zone Green. This comprehensive zoning text amendment will enable energy efficient cutting-edge design and construction of both new and existing buildings.

During public debate of the proposal, wind turbines, green houses, and solar panels received much attention. These elements are emblematic of the green building movement; however, it is the more mundane aspects that will have the most far reaching impact on reducing our carbon footprint.

New York City’s zoning resolution was enacted in 1961. The rules regarding permitted obstructions and rooftop mechanical allowances have remained largely unchanged. Zone Green provides meaningful relief for new exterior insulation on existing buildings, added wall thickness for super-insulated new construction, and rooftop equipment. Green roofs, water retention systems, and landscaping will also be permitted to encroach above height limits. These simple measures will go a great distance in encouraging energy efficient real estate.

Proposal, dubbed the “Zone Green” initiative, would streamline implementation of energy-efficient retrofits for existing buildings and the construction of new green buildings. On February 29, 2012, the City Planning Commission heard testimony on the Department of City Planning’s “Zone Green” zoning text amendment. Planning is seeking to remove regulations that impede property owners from installing energy-saving retrofits in existing buildings and that discourage the development of new energy-efficient buildings. The proposal would broadly exempt from the zoning resolution’s height, floor area, and lot coverage limits certain types and amounts of external insulation, horizontal and vertical sun-control devices, rooftop greenhouses, wind turbines, and solar panels.  (read more…)
