Chapter 6 - Location of District Boundaries

The City of New York
Bill de Blasio, Mayor
City Planning Commission
Marisa Lago, Chair

Except as otherwise specifically provided, all prescribed distances shall be measured in a straight line, not necessarily coinciding with a street line.

The district boundaries on the zoning maps shall be interpreted in accordance with the provisions set forth in Sections 76-12 (Area Enclosed by District Boundary Line), 76-13 (Location of Boundary Line) and 76-14 (Additional Rules of Construction).

In cases where a boundary line extends parallel to the short dimension of the block and no dimensions are shown, such boundary line shall be considered to be located:

(a)        in the case of C1-1, C4-1, C4-2 or C4-4 Districts, 200 feet from the nearest street within the district;

(b)        in the case of C1-2, C1-3, C2-1, C2-2, C2-3, C4-3 or C7 Districts, 150 feet from the nearest street within the district; and

(c)        in the case of all other districts, 100 feet from the nearest street within the district.

In cases where the boundary line is shown by a dimension as being located a specific distance from a street line, this distance shall be considered to be measured from the nearest street line of the street from which dimensioned.

In cases where a Limited Height District boundary line appears to be identical or approximately identical with the boundary line of another district whose location is shown by a dimension, the boundary line of the Limited Height District shall be considered to be identical with the boundary line of the other district.

In cases where the boundary line is given a position within a street, it shall be considered to be in the center of the street.

In cases where a C1 or C2 District is mapped within a Residence District and such C1 or C2 District abuts a street line, the boundary line along such abutting portion shall be deemed to be located in the center of the abutting street.

In cases where a boundary line is shown having a position oblique to the streets bounding the block in which it is located, it shall (unless otherwise fixed) be considered to be the bisector of the angle formed by the intersection of lines 100 feet from and parallel to each of said bounding streets, this distance being measured at right angles to said street lines.

In cases where a boundary line is shown as adjoining a railroad, it shall (unless otherwise fixed) be considered to coincide with the boundary line of the railroad right-of-way.

In cases of parks, cemeteries, or navigable waters, the boundary line shall (unless otherwise fixed) be considered to coincide with the boundary line of the park or the cemetery or the pierhead line, except that in cases where no pierhead line has been established, the shore line shall control.

76-146

Islands

Any island, or portion thereof, outside of the shore or pierhead lines, that is not a public park shall, unless otherwise designated or determined by the City Planning Commission, be considered to be in an R3-2 District.
