8 Introduction to Zoning

Since 1961, the number of zoning districts has more than doubled to address the varied conditions in the city­s neighborhoods, and special purpose districts have been introduced throughout the city that modify the underlying zoning district rules to meet speciƒc planning goals for the area. ™ese have ranged from planning new neighborhoods like Hunters Point South in Queens, enhancing Central Business Districts such as Midtown, or protecting environmentally sensitive areas in Staten Island (see Chapter 7). In addition, to address areas of the city that are not intended to be planned as a district but share common characteristics, the Resolution has incorporated special rules that apply in certain areas (see Chapter 6). ™ese have been utilized to address myriad goals, such as ensuring public access to the city­s waterfront, and facilitating storm recovery aer Hurricane Sandy.

Several new zoning tools have also been created to respond to particular conditions and trends. ™e Zoning Resolution has been changed to help preserve landmarked buildings like Grand Central Terminal, and promote economic diversity and aordability in neighborhoods where residential growth is planned. Incentive zoning has expanded far beyond its initial focus on public open space to meet new policy goals such as improving subway stations, promoting energy e cient buildings and bringing healthy food to underserved neighborhoods.

Rear lot lines are Wide street generally parallel to front lot lines and at no point can ≥75’ they intersect with the street line. Because of the way these Narrow street deƒnitions are fashioned, not every zoning lot has every <75’ type of lot line.

There are three different types of zoning lot lines that can bound each zoning lot – front, side and rear lot lines. The front lot line is along the street.

Not every lot type has every type of lot line.

Each use within a zoning district has a floor area ratio (FAR), which, when multiplied by the area of the zoning lot produces the maximum amount of floor area allowed. On a 10,000 square foot lot, for example, if the permitted uses have a maximum FAR of 2.0, the floor area of the zoning lot cannot exceed 20,000 square feet. This floor area can be configured in many different ways, subject to other bulk regulations.

There are three basic yard types — front yards, side yards and rear yards — that generally correspond to, and border, the three respective lot line types. Through lots often require a rear yard equivalent instead of a rear yards as they have no rear lot lines.

In addition, parking, over time parking regulations have incrementally these also attempt to reŒect the varying rates of parking in some areas with good access to public transportation been added. ™ese originally included regulations demand that dierent commercial, community facility designated in the Resolution, such as the Transit Zone, governing vehicular parking and loading berths to dock and manufacturing uses generate.

22 Introduction to Zoning Streetscape

Since 1961, informed by the contributions of Jane Jacobs Streetscape Regulations and other urbanists, planners in New York City have increasingly recognized the importance of how buildings interact with public areas like the sidewalk, and the Zoning Resolution has evolved to reŒect this.

Vibrant commercial corridors are oen the lifeblood of neighborhoods and in New York City the ground Œoor of the building will oen €hug‚ the sidewalk so 2 that large, transparent show windows displaying retail wares, and frequent store entrances, are readily accessible to passersby. Residential streets, on the other hand, can provide for a degree of separation from the noise, crowds and tra c of the city, and have dierent physical qualities underpinning their success, such as street trees continuously lining the block, building facades maintaining a relatively uniform separation from the sidewalk and architectural articulation that adds visual interest. For both types of conditions, the streetscape, 4 3 or design quality of the street, plays a pivotal role in providing an enjoyable environment for both pedestrians and occupants of the adjoining buildings. 6 Streetscape regulations have no dedicated chapter in the 5 Resolution, and so are oen located within the Chapters governing use, bulk or parking. 1 7 Ground Floor Use Regulations In some Commercial Districts, ground Œoor use A series of streetscape allowances and requirements regulations require uses along the sidewalk to consist help ensure new buildings contribute to their primarily of neighborhood retail and service uses. neighborhoods.

In oors for certain Quality Housing buildings general, only very limited accessory signage is permitted (ZR 23-662, 35-652). in Residence Districts, while Commercial Districts and Manufacturing Districts have more generous allowances. Street Wall Rules Advertising signs are limited to Manufacturing Districts Many contextual districts prescribe where the street wall and a few Commercial Districts .

In the Special Midtown District, some subdistricts have diering provisions that broaden the eligible receiving sites of transferred Œoor area. For example, the ™eater Subdistrict allows transfers from speciƒc theaters around Times Square to other sites within the subdistrict (ZR 81-744). ™e Special West Chelsea District allows zoning lots under or adjacent to the High Line, within the High Line Transfer Corridor, to transfer development rights to facilitate views from the High Line park itself (ZR 98-30).

In contextual districts, this is often a lot areas may apply building footprint. Yard requirements may come in the fixed height limit. In non-contextual districts, a form of front yard, side yard or rear yard regulations sky exposure plane may be applied
