Chapter 1 Special Midtown District -- (MID)

The “Special Midtown District” established in this Resolution is designed to promote and protect public health, safety and general welfare. These general goals include, among others, the following specific purposes:

1. to strengthen the business core of Midtown Manhattan by improving the working and living environments;


2. to stabilize development in Midtown Manhattan and provide direction and incentives for further growth where appropriate;


3. to control the impact of buildings on the access of light and air to the streets and avenues of Midtown;


4. to link future Midtown growth and development to improved pedestrian circulation, improved pedestrian access to rapid transit facilities, and avoidance of conflicts with vehicular traffic;


5. to preserve the historic architectural character of development along certain streets and avenues and the pedestrian orientation of ground floor uses, and thus safeguard the quality that makes Midtown vital;


6. to continue the historic pattern of relatively low building bulk in midblock locations compared to avenue frontages;


7. to improve the quality of new development in Midtown by fostering the provision of specified public amenities in appropriate locations;


8. to preserve, protect and enhance the character of the Theater Subdistrict as the location of the world's foremost concentration of legitimate theaters and an area of diverse uses of a primarily entertainment and entertainment-related nature;


9. to strengthen and enhance the character of the Eighth Avenue Corridor and its relationship with the rest of the Theater Subdistrict and with the Special Clinton District;


10. to create and provide a transition between the Theater Subdistrict and the lower-scale Clinton community to the west;


11. to preserve, protect and enhance the scale and character of Times Square, the heart of New York City's entertainment district, and the Core of the Theater Subdistrict, which are characterized by a unique combination of building scale, large illuminated signs and entertainment and entertainment-related uses;


12. to preserve, protect and enhance the character of Fifth Avenue as the showcase of New York and national retail shopping;


13. to preserve the midblock area north of the Museum of Modern Art for its special contribution to the historic continuity, function and ambience of Midtown;


14. to protect and strengthen the economic vitality and competitiveness of the East Midtown Subdistrict by facilitating the development of its exceptional and sustainable buildings and enabling improvements to the pedestrian and mass transit circulation network;


15. to ensure that development within the East Midtown Subdistrict occurs on sites that meet sound site planning criteria and therefore can accommodate additional density as appropriate;


16. to protect and strengthen the role of landmark buildings as important features of the East Midtown Subdistrict;


17. to protect and enhance the role of Grand Central Terminal as a major transportation hub within the City, to expand and enhance the pedestrian and mass transit circulation network connecting Grand Central Terminal to surrounding development, to minimize pedestrian congestion and to protect the surrounding area’s special character;


18. to expand the retail, entertainment and commercial character of the area around Pennsylvania Station and to enhance its role as a major transportation hub in the city;


19. to provide freedom of architectural design within limits established to assure adequate access of light and air to the street, and thus to encourage more attractive and economic building forms without the need for special development permissions or “negotiated zoning”; and


20. to promote the most desirable use of land and building development in accordance with the District Plan for Midtown and thus conserve the value of land and buildings and thereby protect the City’s tax revenues.

For purposes of this Chapter, matter in italics is defined in Sections 12-10, 81-261, 81-271 or 81-613 (Definitions).

2. the developer has agreed in a writing recorded against the property to implement a plan approved by the Commission and New York City Transit for the provision of a subway station improvement in accordance with the provisions of Section 74-634 (Subway station improvements in Downtown Brooklyn and in Commercial Districts of 10 FAR and above in Manhattan).


2. Where the requirements of Article IX, Chapter 5, are not waived, modifications of the underlying district #bulk# regulations as set forth in this Chapter shall prevail over any inconsistent #bulk# regulations in Article IX, Chapter 5.

Any #floor area#bonus granted by certification for through #block# gallerias prior to August 6, 1998, shall remain in effect, provided however that such certification shall automatically lapse if substantial construction, in accordance with the plans for which such certification was granted, has not been completed within four years from the effective date of such certification.

Within the #Special Midtown District#, for each square foot of #public plaza# provided on a #zoning lot#, the basic maximum #floor area# permitted on that #zoning lot# under the provisions of Section 81-211 (Maximum floor area ratio for non-residential or mixed buildings) may be increased by six square feet, provided that in no case shall such bonus #floor area# exceed a #floor area ratio# of 1.0.

This Section shall be applicable in all underlying districts throughout the #Special Midtown District#, except that there shall be no #floor area# bonus for a #public plaza# that is:

1. on #zoning lots# in the C5P District within the Preservation Subdistrict;


2. within 50 feet of a #street line# of a designated #street# on which retail or #street wall# continuity is required, pursuant to Sections 81-42 (Retail Continuity Along Designated Streets) or 81-43 (Street Wall Continuity Along Designated Streets);


3. on a #zoning lot#, any portion of which is within the Theater Subdistrict Core, as defined in Section 81-71 (General Provisions); and


4. on #zoning lots#, any portion of which is in the Grand Central Core Area, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, or on #qualifying sites#, as defined in Section 81-613, in any other subarea of the East Midtown Subdistrict.

All #public plazas# provided within the #Special Midtown District# shall comply with the requirements for #public plazas# set forth in Section 37-70, inclusive.

A major portion of a #public plaza# may overlap with a sidewalk widening which may be provided to fulfill the minimum pedestrian circulation space requirements set forth in Section 81-45 (Pedestrian Circulation Space), provided that the overlapping portion of the #public plaza# also conforms to the design standards of Section 37-50 (REQUIREMENTS FOR PEDESTRIAN CIRCULATION SPACE) for a sidewalk widening. Such sidewalk widening may be included in the major portion of a #public plaza# for purposes of calculating the proportional restrictions set forth in Section 37-715.

1. Elimination or reduction in size of existing #publicly accessible open area# or other public amenities
   
   No existing #publicly accessible open area# or other public amenity, open or enclosed, for which a #floor area# bonus has been utilized, shall be eliminated or reduced in size, except by special permit of the City Planning Commission, pursuant to Section 74-761(Elimination or reduction in size of bonused public amenities).


2. Kiosks and open air cafes
   
   Kiosks and open air cafes may be placed within an existing #publicly accessible open area# for which a #floor area# bonus has been received by certification, pursuant to Section 37-73(Kiosks and Open Air Cafes).


3. Nighttime closing of existing #publicly accessible open areas#
   
   The City Planning Commission may, upon application, authorize the closing of an existing #publicly accessible open area# for which a #floor area# bonus has been received,during certain nighttime hours, pursuant to Section 37-727 (Hours of ccess) .


4. Special provisions for certain #covered pedestrian spaces#
   
   Where a portion of an existing #covered pedestrian space# was designated by a special authorization of the City Planning Commission prior to May 13, 1982, to be used for off-street loading after business hours, the Commission may,by special permit, after public notice and hearing, and subject to City Council action, allow relocation of the loading facilities and modifications relating to the loading berth requirements, provided that such modifications will result in substantial improvement of the pedestrian circulation system and amenities within the existing #covered pedestrian space# without adversely affecting the operation of off-street loading facilities.


5. Elimination or reduction in size of non-bonused open area on a #zoning lot# containing a bonused amenity
   
   Any existing open area for which a #floor area# bonus has not been utilized that occupies the same #zoning lot# as an existing #publicly accessible open area# or other public amenity, open or enclosed, for which a #floor area# bonus has been utilized, may be reduced in size or eliminated only upon certification of the Chairperson of the City Planning Commission that all bonused amenities comply with the standards under which such #floor area# bonus was granted.

Where a #public plaza# is located on a #zoning lot# divided by a district boundary, the #floor area# bonus for such #public plaza# may be credited to either portion of the #zoning lot# regardless of the #public plaza's# location or the date when the #zoning lot# was created, provided that the amount of such bonus permitted on either portion of the #zoning lot# shall not exceed the maximum amount that would be permitted on such portion if it were a separate #zoning lot# and subject to all other applicable provisions of Article VII, Chapter 7.

For #residential buildings# or #residential# portions of #mixed buildings# in the #Special Midtown District#, the maximum #floor area ratio# for each underlying district is as follows:

1. In the C5-P District the maximum #floor area ratio# is 8.0, and no additional #floor area# shall be allowed above this limit.


2. In all underlying districts other than the C5-P District, except as provided in paragraph (c) of this Section, the maximum #residential floor area ratio# is 10.0.


3. In any underlying district other than a C5-P, C6-4 or C6-5 District, or in a C6-4 or C6-5 District within the Theater Subdistrict where a #zoning lot# has been granted bonus #floor area# or other #floor area# allowances in accordance with the provisions of Section 81-741 (General provisions),such #zoning lot# shall qualify for a maximum #residential floor area ratio# of 12.0 if the #development# or the #building# containing the #enlargement# includes recreational space for the #residential# occupants in an amount not less than 13 square feet for each #rooming unit#, 16.25 square feet for each #dwelling unit#,or a total area of at least 5,000 square feet, whichever is greater.The recreational space may be located at any level including a roof. Such recreational space shall:
   
   
   1. be restricted to #residential# occupants of the #development# or the #building# containing the #enlargement# and their guests,for whom no admission or membership fees may be charged;
   
   
   2. be directly accessible from a lobby or other public area served by the #residential# elevators;
   
   
   3. be landscaped, including trees or shrubbery, except where covered or developed with recreational facilities and seating areas;
   
   
   4. contain not less than 500 square feet of continuous area on a single level with no dimension of less than 15 feet;
   
   
   5. have not less than 50 percent of the area open from its lowest level to the sky. The remaining portion may be roofed and up to 50 percent of its perimeter may be enclosed.In no event may more than 25 percent of the required recreational space be fully enclosed.All enclosures shall be transparent except when located within the #building#. Covered areas shall contain recreational facilities or eating areas.

A copy of requirements (c)(1) through (c)(5), as set forth in this Section, shall be permanently posted in a conspicuous place within each recreational space.

When a #building# containing #residential uses# is located on the same #zoning lot# as another #building#, the provisions of Section 23-70 (MINIMUM REQUIRED DISTANCE BETWEEN TWO OR MORE BUILDINGS ON A SINGLE ZONING LOT) shall not apply.

For all #buildings# in the #Special Midtown District#, except as provided in Section 81-90 (SPECIAL REGULATIONS FOR PRESERVATION SUBDISTRICT), the height and setback regulations of the underlying districts are superseded by the provisions of this Section and by the two alternate sets of regulations controlling the height and setback of #buildings# as set forth in Sections 81-26 (Height and Setback Regulations--Daylight Compensation) and 81-27 (Alternate Height and Setback Regulation--Daylight Evaluation), respectively. For the purposes of applying height and setback regulations, the term “#buildings#” shall include #buildings or other structures#, except if specifically stated otherwise.

For the purposes of Sections 81-25 through 81-27, inclusive, all #buildings# on a #zoning lot# shall be considered a single #building#. Existing portions of such #buildings# are referred to as an “existing #building#.” A “new #building#” shall include #developments#, #enlargements# or alterations that increase the width or height of a #building# wall.

An applicant for plan approval by the Department of Buildings may elect to be governed by the provisions of either Section 81-26 or 81-27 in addition to the provisions of this Section.

This Section sets forth the provisions that are common to both sets of regulations.

The common purpose of these two sets of regulations is to offer maximum design flexibility while setting reasonable but firm standards to protect access of light and air to public #streets# and adjacent #buildings#.

This purpose is implemented by the two alternate sets of regulations, which are based on two distinct approaches. Both sets are concerned with daylight at #street# level.

The daylight compensation regulations require any #building# generally to be built within a sky exposure curve which relates required setbacks to #building# heights. Within limits, the #buildings# may encroach outside the curve but only if extra setbacks or recesses provided elsewhere on the same #street# frontage of the #zoning lot# compensate for the #encroachment#. In the regulations, the sky exposure curve for three #street# width categories is represented in each case by a table of required setbacks related to #building# heights.

The daylight evaluation regulations measure and evaluate portions of sky blocked by a #building# as viewed from specified #vantage points# in the #street#. The #building# is plotted on #daylight evaluation charts# representing the #zoning lot's# available day light from specified #vantage points#, measured in daylight squares as defined in paragraph (b) of Section 81-272. Daylight blockage by the #building# is then measured to determine the #building's# score on each frontage and the average score for the #building# as a whole. The regulations specify the minimum passing scores for compliance.

Except as set forth in this Section, structures which under the provisions of Sections 33-42 or 43-42 (Permitted Obstructions)or 34-11 or 35-11 (General Provisions), are permitted to penetrate a maximum height limit or a #sky exposure plane# shall not be permitted as exceptions to the height limitations, setback requirements or rules for the measurement of #encroachments# or #compensating recesses# set forth in Section 81-26 (Height and Setback Regulations), nor shall they be excluded in determining daylight blockage pursuant to the provisions of Section 81-27 (Alternate Height and Setback Regulations).

The following shall be permitted as exceptions to the height regulations, setback requirements or rules for the measurement of #encroachments# or #compensating recesses#, set forth in Section 81-26 (Height and Setback Regulations), and shall be excluded in determining daylight blockage, pursuant to the provisions of Section 81-27 (Alternate Height and Setback Regulations);

1. Unenclosed balconies conforming to the provisions of Section 23-13 (Balconies); and


2. Exterior wall thickness, up to eight inches, where such wall thickness is added to the exterior face of a #building# wall existing on April 30, 2012, provided the added wall thickness has a thermal resistance (R-value) of at least 1.5 per inch. Where #buildings# that have added exterior wall thickness pursuant to this Section are #enlarged#, such #enlarged# portion may similarly penetrate a maximum height limit in order to align with the exterior walls of the existing #building#, provided such #enlargement# contains less #floor area# than the existing #building#, and there is no penetration of #floor area# above a maximum height limit.

The provisions of Sections 81-26 (Height and Setback Regulations--Daylight Compensation) and 81-27 (Alternate Height and Setback Regulations--Daylight Evaluation) are supplemented and modified by special provisions applying in the Fifth Avenue Subdistrict, as set forth in Sections 81-81 (General Provisions) and 81-83 (Special Street Wall Requirements) or in the Theater Subdistrict as set forth in Sections 81-71 (General Provisions) and 81-75 (Special Street Wall and Setback Requirements) or in the East Midtown Subdistrict as set forth in Sections 81-61 (General Provisions), 81-66 (Special Height and Setback Requirements), inclusive, or 81-671 (Special street wall requirements).

The provisions of Sections 81-26 and 81-27 are not applicable in the Preservation Subdistrict, where height and setback is regulated by the provisions of Section 81-90 (SPECIAL REGULATIONS FOR PRESERVATION SUBDISTRICT), or in the Penn Center Subdistrict as set forth in Section 81-532 (Special street wall requirements).

In the #Special Midtown District#, the City Planning Commission may modify the special height and setback regulations set forth in this Chapter only in accordance with the following provisions:

Compensating recess

A portion of a #zoning lot# which, at the #building# height selected for determining compliance with the provisions of Section 81-26 (Height and Setback Regulations), lies in the #free zone# (Zone A on the #encroachment grid#), is not covered by any portion of a #building# and qualifies as compensating for #encroachments# beyond the #free zone# under the provisions of Section 81-264 (Encroachments and compensating recesses). (See Illustration of #Compensating Recess# and #Encroachment#)

COMPENSATING RECESS AND ENCROACHMENT
                                 (81-265.1)

Encroachment
A projection beyond the #setback line#, the #free zone# or the #half-setback line# by any portion of a #building# that exceeds the maximum height permitted at the #street line#. (See Illustration of #Compensating Recess# and #Encroachment#)

Encroachment grid
A plan drawing of the #zoning lot# at any given height above #curb level# selected to determine compliance with the provisions of Section 81-26 (Height and Setback Regulations) and showing, for that height, #street lines#, #setback lines#, #half-setback lines#, #Zone A# (the #free zone#), #Zones B# and #C# (#encroachment zones#) and, where applicable, the #ten-foot setback line#. The #encroachment grid# serves as a device for measuring areas of #encroachment# beyond the #free zone# and areas of #compensating recess# within the #free zone#. (See Illustration of #Encroachment Grid#)

ENCROACHMENT GRID
              (81-265.2)

Free zone
That portion of a #zoning lot#, at any given height, which may be covered by a #building# without coverage constituting an #encroachment# that requires daylight compensation.

In addition to the area that lies behind a #setback line# or #lines#, the #free zone# shall include areas between the #setback line# and either the #half-setback line# or the #ten-foot setback line#, whichever is further from the #street line#, and which qualify as #free zone# areas under the #middle one-third rule#. The #free zone# is referred to as #Zone A# on the #encroachment grid#.

               Free Zone
               (81-265.3)

Half-setback line
A line drawn parallel to a #street line# and halfway between the #street line# and the #setback line#. (See Illustration of #Setback# and #Half-Setback Lines#)

Middle one-third rule
The rule under which, for the middle one-third of the #front lot line# length, the #free zone# includes area between the #setback line# and either the #half-setback line# or the #ten-foot setback line#, whichever is further from the #street line#. However, on a #corner lot# the #free zone# does not extend beyond the #setback line# along an intersecting #street#. (See Illustrations of #Middle One-Third Rule#)


MIDDLE ONE-THIRD RULE
               (81-265.4)

Setback line
A line drawn in plan parallel to a #street line# and showing for a given #building# height the minimum depth to which a #building# is required to be set back from the #street line# by the applicable depth to height chart in Section 81-263 (Standard setback requirements). Required setbacks, established by the chart, increase with the #building's# height. (See Illustration of #Setback# and #Half-Setback Lines#)

SETBACK AND HALF-SETBACK LINES
                         (81-265.5)

Street frontage zone
A portion of a #zoning lot# which lies within an area bounded by a continuous #front lot line# and either the center line of the #block# or a line 100 feet distant from and parallel to that #front lot line#, whichever is closer to that #front lot line#. There shall be a #street frontage zone# for each #zoning lot street# frontage. (See Illustration of #Street Frontage Zones#)

STREET FRONTAGE ZONES
             (81-265.6)

Ten-foot setback line
A line which is parallel to the #street line# at a depth of 10 feet and represents the minimum distance any portion of a #building# exceeding the maximum height at the #street line# is required to be set back from the #street line#. A greater setback distance may be required by a #setback line# or a #half-setback line# depending upon the #building# height for which such #setback line# or #half-setback line# is established.

TEN-FOOT SETBACK LINE ON AN ENCROACHMENT GRID
                                         (81-265.7)

Zone A, Zone B, Zone C

"Zone A," "Zone B" and "Zone C" are zones on an #encroachment grid# defined as follows:

1. #Zone A# is the #free zone#.


2. #Zone B#, an #encroachment# zone, is the zone, exclusive of any area in #Zone A# and any area closer to the #street line# than the #ten-foot setback line#, which lies between the #setback line# and either the #half-setback line# or the #ten-foot setback line#, whichever is further from the #street line#.


3. #Zone C#, an #encroachment# zone and penalty zone, is the zone, exclusive of any area closer to the #street line# than the #ten-foot setback line#, which lies between the #halfsetback line# and the #ten-foot setback line#.

1. General provisions
   
   The front wall of a #building# at the #street line# shall not exceed the height limit applying along the #street# on which it fronts. Maximum front wall heights at the #street line# vary with the width of the #street# on which the wall fronts, as follows:

   60 or less	90
   75 or 80	120
   100 or more	150



2. Special provisions for #corner lots#
   
   For a #corner lot# with frontage on #streets# of different widths, the maximum front wall height at the #street line# of the narrower #street# may be increased above that indicated in paragraph (a) in accordance with either one of the following rules:
   
   Rule 1:
   
   The maximum front wall height at the #street line# for the wider #street# may extend up to 100 feet from the corner along the #street line# of the narrower #street#; or
   
   SPECIAL RULE 1 FOR CORNER LOTS
                       (81-262b.1)
   
   Rule 2:
   
   For any length of frontage from the corner along the narrower #street#, a maximum height for such length of frontage may apply, which shall be the weighted average of (1) the height permitted under Rule 1 for the first 100 feet from the corner, and (2) the standard height limit for front walls on the narrower #street# for the remainder of the frontage. (See Illustration of Special Rules for #Corner Lots#)
   
   SPECIAL RULE 2 FOR CORNER LOTS
                       (81-262b.2)

#Buildings# shall comply with the regulations of this Section.

1. Ten-foot setback requirement
   
   Above the maximum height permitted at the #street line# pursuant to the provisions of Section 81-262, every portion of a #building# shall be set back at least 10 feet from the #street line#.


2. General setback provisions; depth to height charts
   
   Above the maximum height permitted at the #street line#, #buildings#, in addition to meeting the requirements of paragraph (a) of this Section, are required to be set back behind the applicable #setback line#, the depth of the #setback line# at any point depending upon the height of the wall at that point in accordance with the requirements of applicable Tables A, B or C of this Section presenting required setbacks from #streets# 60 feet or less, 75 or 80 feet, or 100 or more feet in width, respectively.

   690	49.25
   700	49.50
   710	50.00
   Above 710	For every 10 feet the depth shall increase by one foot



3. Use of tables
   
   To comply with the setback requirements of this Section a #building# at any height shall be set back at least to the depth of the #setback line# indicated on the applicable table.
   
   For heights between those shown on the table, the depth of the #setback line# shall be interpolated.
   
   Required depths of #setback lines# shall be rounded off to the next highest half foot.
   
   The setback requirements apply only to portions of #buildings# above the maximum height permitted at the #street line#, so that required setbacks on the narrower #street# frontage of a #corner lot# shall apply only to heights above the maximum front wall heights permitted by the #corner lot# provisions of paragraph (b) of Section 81- 262 (Maximum height of front wall at the street line).


4. #Middle one-third rule#
   
   A #building# may penetrate beyond the #setback line# at any height if the penetration is confined to the middle third of the #front lot line# length and complies in all respects with the #middle one-third rule# as defined in Section 81- 261 (Definitions).

In addition to complying with the setback requirements of Section 81-263 (Standard setback requirements), a #building# shall not at any height encroach beyond a #half-setback line# or a #ten-foot setback line#, except as provided below. For each #street frontage zone# and for all #street frontage zones#, taken together on a single #encroachment grid#, a #building# shall not, at any level, have an aggregate area of #encroachment# beyond the #setback line#, other than in any #free zones#, greater than the aggregate area of #compensating recess# at such level.

Except as provided below, an area of #compensating recess# in one #street frontage zone# shall not be used to compensate for #encroachment# in another #street frontage zone#. However, a #building# with a #street frontage zone# which lies along a north-south #wide street# and does not meet the above requirements because of excessive #encroachment# will be in compliance with the #street frontage zone# requirements of this Section if compensation is provided for such excessive #encroachment# by an overlapping #street frontage zone#.

The requirement that the aggregate area of #compensating recess# at least equal the aggregate area of #encroachment#, as set forth in this Section, shall also apply to any #building# which encroaches beyond a #half-setback line# and which is therefore subject to the provisions of Section 81-265 (Encroachment limitations by length and height rules). (See Illustration of Encroachments and Compensating Recesses)

1. Rules for measuring #encroachments# and recesses
   
   Areas of #encroachment# and #compensating recess# shall be measured in plan on one or more #encroachment grids# showing for the #zoning lot#, at a given height level, the #street lines#, the #setback lines#, the #half-setback lines#, the #ten-foot setback lines#, #Zones A#, #B# and #C# and the #street frontage zones#.
   
   ENCROACHMENTS AND COMPENSATING RECESSES
                                        (81-264a)
   
   The scale of the #encroachment grid# shall be not more than 20 feet to the inch. All #buildings#, existing and proposed, shall be located accurately on the grid in plan at the height level selected to demonstrate compliance. For each #street frontage zone#, the areas of the #building’s encroachment# in #Zones B# and #C# and the #compensating recess# areas not covered by any #building# in #Zone A# shall be measured on the #encroachment grid#.


2. Limits of #encroachment#
   
   Except as provided in paragraph (d) of this Section for existing #buildings# below specified heights, #encroachment# is limited as follows:
   
   
   1. For each #street frontage zone#, at every height above the maximum front wall height at the #street line#, the area within #Zone A# that is not covered by a #building# and qualifies as #compensating recess# area shall, in the aggregate, equal or exceed the aggregate area in #Zones B# and #C# that is encroached upon by a #building# at such height.
   
   
   2. No part of a #building# shall encroach into #Zone C# unless it complies with the provisions of Section 81- 265.
   
   
   3. On #corner lots#, the projection of a #building# beyond the #setback# or #half-setback line# on the narrower #street# shall not count as an #encroachment# except at heights above the maximum height permitted at the #street line# by the #corner lot# provisions in paragraph (b) of Section 81-262 (Maximum height of front wall at the street line).


3. Limitations on #compensating recess#
   
   #Compensating recess# areas are subject to the following limitations:
   
   
   1. Any required #compensating recess# area shall extend without diminution of dimensions downward at least to the lowest level at which any #encroachment# into #Zone B# or #C# occurs and upward to the sky. (See Illustration of Extension Downward of Compensating Recess Area)
      
      EXTENSION DOWNWARD OF COMPENSATING RECESS AREA
                                                     (81-264c1)
   
   
   2. #Compensating recess# area shall be visible when viewed from at least one adjacent #street# along a line that intersects the #front lot line# of the #zoning lot# at right angles. (See Illustration of Visibility of Compensating Recess Area)
      
      VISIBILITY OF COMPENSATING RECESS AREA
                                       (81-264c2)
   
   
   3. The minimum length of a #compensating recess#, measured parallel to the #street line#, and behind the #setback line#, is 30 feet, except for any uncovered portion of an area that qualifies as #Zone A# under the #middle one-third rule# or an uncovered area located behind two intersecting #setback lines#. An uncovered area between the #setback# and #half-setback lines# that qualifies as #Zone A# under the #middle one-third rule# is not subject to the minimum length requirement. (See Illustration of Minimum Length of Compensating Recess)
      
      MINIMUM LENGTH OF COMPENSATING RECESS
                                         (81-264c3)
   
   
   4. #Compensating recess# area shall be within 100 feet of a #front lot line#.


4. Existing #buildings# on the #zoning lot#
   
   Where a #zoning lot# contains an existing #building# which exceeds a height limit, an #enlargement# or #development# on such #zoning lot# shall comply with the following provisions:
   
   
   1. For each #street frontage zone#, if the existing #building# is not more than 120 feet in height at any point and encroaches into #Zone B# or #Zone C# or beyond the #ten-foot setback line# along the frontage of a #street# 60 feet wide, or if the existing #building# is not more than 150 feet in height at any point and encroaches into #Zone B# or #Zone C# or beyond the #ten-foot setback line# along the frontage of a #street# 75 or more feet in width, the new #building# or #enlargement# is not required to compensate for such #encroachment# by the provision of #compensating recess# areas. #Encroachment# by such an existing #building# into #Zone C# or beyond the #tenfoot setback line# will not subject the new #building# or #enlargement# to the provisions of Section 81-265 unless the new #building# or #enlargement# also encroaches into #Zone C#.
   
   
   2. For each #street frontage zone#, space above such existing #building# and within #Zone A# on the #encroachment grid# may count as #compensating recess# area for the new #building# or #enlargement# provided that such space is at or below the lowest level of any compensable #encroachment# by the new #building# or #enlargement#, that it is located within the same #street frontage zone# as that compensable #encroachment#, and that it qualifies in all respects under the provisions of paragraph (c) of this Section (Limitations on #compensating recess#).
   
   
   3. For each #street frontage zone#, if an existing #building# more than 120 feet in height at any point encroaches into #Zone B# or #Zone C# or beyond the #ten-foot setback line# along the frontage of a #street# 60 feet wide, or if an existing #building# more than 150 feet in height at any point encroaches into #Zone B# or #Zone C# or beyond the #ten-foot setback line# along the frontage of a #street# 75 or more feet in width, the #encroachment# of such #building# into #Zone B# or #Zone C# or beyond the #ten-foot setback line# at any height shall be subject to the requirements for #compensating recess# areas set forth in paragraph (b)(1) of this Section, as if it were a new #building#. Where such an existing #building# encroaches into #Zone C# or beyond the #tenfoot setback line#, the provisions of paragraph (f)(2) in Section 81-265 shall apply in addition to the provisions of this Section. (See Illustration of Existing Buildings on the Zoning Lot)
      
      EXISTING BUILDINGS ON THE ZONING LOT
                                   (81-264d3)

Above the maximum height of a front wall at the #street line# as set forth in Section 81-262, a #building# may only encroach beyond the #half-setback line# if it complies with the provisions of this Section and if the area of #compensating recess# equals or exceeds the area of #encroachment# in #Zones B# and #C# in accordance with the provisions of Section 81-264 (Encroachments and compensating recesses).

1. Special limitations
   
   No #encroachment# beyond the #half-setback line# shall be within 30 feet of a #side lot line#. (See Illustration of Prohibited and Allowed Encroachment Beyond Half-Setback Line)
   
   
   PROHIBITED AND ALLOWED ENCROACHMENT BEYOND
                              HALF-SETBACK LINE
                                        (81-265a)


2. General provisions
   
   The length, depth, height and area of #encroachments# along any #street# frontage all contribute to a #building's# impact on daylight access. In order to determine whether the depth of a #building's encroachment# into #Zone C# is justified, the length of the #encroachment#, measured parallel to the #street line#, and its height above #curb level# must also be evaluated. The extent of #encroachment# also must be considered in relation to the extent of the area of #compensating recess# in the same #street frontage zone#. The purpose of the length and height rule is to ensure, in the case of #encroachments# beyond the #halfsetback line#, that the closer a #building# comes to the #street line#, the less will be the length of its #encroachment#, its height or both. (See Illustration of Elements Analyzed)
   
   The elements comprising this analysis are represented by symbols and are as follows:
   
   
   1. 
      
      
      
      

      De	(depth of #encroachment#) means depth of #encroachment# beyond the #setback line#. Depth of #encroachment# is measured perpendicularly to the #setback line#.
      D	(depth of #setback line#) means depth of #setback line# from the #street line# or depth of #ten-foot setback line# from the #street line#, whichever depth is greater.

   
   
   2. 
      
      
      
      

      Le	(length of #encroachment#) means total length of #encroachment# outside the #half-setback line#. Length of #encroachment# is measured as the total length of the #encroachments'# projections on the #street line#.
      L	(length of #front lot line#) means the length of the #front lot line# along the particular #street#. However, the length of the #front lot line# for the purposes of this Section shall not exceed 300 feet, irrespective of the actual #lot line# length.

   
   
   3. 
      
      
      
      

      Le	(length of #encroachment#) as defined in paragraph (b)(2) of this Section.
      Lr	(length of recess) means total length of #setback line# not encroached upon by a #building#.

   
   
   4. 
      
      
      
      

      H	(height of #encroachment#) means the height of the #encroachment# above #curb level#.
      L	(length of #front lot line#) as defined in paragraph (2) of this Section.

   
   
   5. 
      
      
      
      

      Ar	(area of #compensating recess#) means area of #compensating recess# in the particular #street frontage zone#. Area of #compensating recess# is calculated to a depth of 100 feet from the #street line#.
      Ae	(area of #encroachment#) means area of #encroachment# beyond the #setback line#. Area of #encroachment# is calculated to a depth of 100 feet from the #street line#.

      
      
      Values for the elements in paragraphs (b)(1) through (b)(5) shall be found for each #street frontage zone# on which there is any #encroachment# beyond the #half-setback line#.
      
      
               ELEMENTS ANALYZED
                         (81-265b)
      
      The elements, weighted according to the effects on daylight access, are represented in the formulas and charts that control the depth, length and height of #encroachments#, as set forth in paragraph (c) of this Section.
      
      #Encroachments# of proposed #buildings# or #enlargements# beyond the #half-setback line# are permitted only if in compliance at every point with the formulas in paragraph (c) of this Section. Aside from this general requirement, specified points at which the length, depth, height and area rules shall be applied are presented in paragraphs (d) and (e) of this Section.


3. #Encroachment# limitations by Formulas 1 and 2
   
   Where applicants elect to have their #buildings# regulated by the formulas, #buildings# shall comply with both Formula 1 and Formula 2 as set forth in this paragraph. Elements of the formulas and the symbols by which they are represented are as set forth in paragraph (b) of this Section.
   
   
   
   The maximum height of #encroachment# (H) allowed by Formula 1 may be modified for certain conditions, as follows:
   
   
   1. For short frontages
      
      For any frontage less than 200 feet in length, the maximum
      
      
      found by applying Formula 1 may be increased by the following multiplier:
      
   
   
   2. For large areas of #compensating recess#
      
      To the extent that the aggregate area of #compensating recess# (Ar) exceeds the aggregate area of #encroachment# (Ae), the maximum
      
      
      
      found by applying Formula 1 may be increased by the following multiplier:
      
      
      For the purposes of this modification, the measurement of the area of #compensating recess# (Ar) and the area of #encroachment# (Ae) in each particular #street frontage zone# shall be made on the #encroachment grid# at the height level for which #encroachments# beyond the #half-setback line# are checked. The #encroachment grid# shall include all #street frontage zones#. (Ar) shall include all areas of #compensating recess# in the particular #street frontage zone#, whether or not connected, and (Ae) shall include all #encroachments# in both #Zone B# and #Zone C# in the same #street frontage zone#, whether or not such #encroachments# are connected.


4. Measurement of #encroachments#
   
   The points at which the formulas are applied will depend upon the shape and dimensions of the #encroachments# beyond the #half-setback line# and shall be in accordance with the provisions of this paragraph and paragraph (e) of this Section.
   
   Where the #encroachments# along a single #street# frontage are not connected outside the #half-setback line#, each #encroachment# shall be measured separately in accordance with the provisions of paragraph (e). However, at any given height, where such non-contiguous #encroachments# occur, the #encroachments# shall be examined together, and the length of #encroachment# (le) shall be the total of the (le) for the individual #encroachments#. (See Illustration of Noncontiguous #Encroachments#)
   
   NONCONTIGUOUS ENCROACHMENTS
                            (81-265d)


5. Heights and depths at which formulas are applied
   
   Heights and depths at which the formulas shall be applied are set forth in this paragraph. In addition to meeting the requirements of paragraphs (e)(1) and (e)(2) of this Section, the applicant shall demonstrate that there is no height at which the proposed #building# or #enlargement# fails to comply with the formulas in paragraph (c) of this Section.
   
   
   1. Standard requirement where length of #encroachment# is uniform
      
      Where the length of the #encroachment# (Le) is uniform for the entire height of the #encroachment# (H) and the entire depth (De) at every height, the length, depth and height rules expressed in the formulas shall be applied only at the height where (De/D) is greatest and at the outermost edge of the #encroachment#. (See Illustration of Uniform Length of #Encroachment#)
      
      UNIFORM LENGTH OF ENCROACHMENT
                               (81-265e1)
   
   
   2. Standard requirement where length of #encroachment# is not uniform
      
      Where the length of the #encroachment# (Le) is not uniform, the rules shall be applied at the height level where (De/D) is greatest and also at the height level where the length of #encroachment# (Le) is greatest. If the greatest length of #encroachment# is uniform for part of the #building's# height, the rules shall be applied at the highest level at which such greatest length of #encroachment# occurs. (See Illustrations Where Length of #Encroachment# is Not Uniform).
      
      If for a particular height level, the length of the #encroachment# (Le) varies with the depth of the #encroachment# (De), the largest (Le) of this #encroachment# shall be used together with the largest de in applying the rules as if the #encroachment# were of uniform length as provided in paragraph (e)(1) of this Section.
      
      
      WHERE LENGTH OF ENCROACHMENT IS NOT UNIFORM
                                             (81-265e2)


6. #Encroachments# by existing #buildings#
   
   When a #zoning lot# contains an existing #building# which encroaches beyond a #half-setback line# or a #ten-foot setback line#, an #enlargement# or #development# on such #zoning lot# shall comply with the following provisions:
   
   
   1. Existing #buildings# below specified heights
      
      
      1. Except as provided in paragraph (f)(1)(ii) of this Section, an existing #building# not more than 120 feet in height shall not be considered in applying the length and height rules even though a portion of such #building# encroaches beyond the #halfsetback line# or #ten-foot setback line# along a 60 foot wide #street# and an existing #building# not more than 150 feet in height shall not be considered in applying the length and height rules even though a portion of such #building# encroaches beyond the #half-setback line# or #tenfoot setback line# along a #street# 75 or more feet in width.
      
      
      2. However, the area occupied by the existing #building# shall be included in the calculation of (Ar/Ae) for the modification of Formula 1 allowed in the case of large areas of #compensating recess#, as set forth in paragraph (c)(2) of this Section.
   
   
   2. Existing #buildings# above specified heights
      
      Where an existing #building# more than 120 feet in height encroaches beyond the #half-setback line# or #ten-foot setback line# along a 60 foot wide #street# or where an existing #building# more than 150 feet in height encroaches beyond the #half-setback line# or #ten-foot setback line# along a #street# 75 or more feet in width, the following provisions, in addition to those of paragraph (d)(3) of Section 81-264 (Encroachments and compensating recesses), shall apply:
      
      
      1. no new construction on the #zoning lot# shall encroach beyond the #half-setback line# along any #street#, and
      
      
      2. the length and height rules of this Section shall not apply.

In C5-3, C6-6 or C6-7 Districts, where a special permit application is made pursuant to Section 74-71 (Landmark Preservation) for modification of #bulk# regulations on a #zoning lot# containing a landmark, or where a special permit application is made pursuant to Section 74-79 for transfer of development rights from a landmark site and the #floor area# represented by such transferred development rights exceeds 20 percent of the basic maximum #floor area# permitted on the #zoning lot# receiving the development rights, such application may include a request for modification of the height and setback regulations set forth in Sections 81-261 to 81-265, inclusive, relating to Height and Setback Regulations - Daylight Compensation. The City Planning Commission may authorize such height and setback modifications subject to the following conditions:

1. the applicant shall demonstrate to the satisfaction of the Commission that a feasible design for the proposed #development# or #enlargement# which accommodates the permitted #floor area# is not possible under the provisions of Sections 81-261 to 81-265, inclusive, and shall further indicate for the proposed design where and to what extent deficiencies of #compensating recess# are necessary or compliance with the length and height rules is not possible. Scale drawings shall be used in presenting the analyses required herein; and


2. the Commission shall make the following findings in addition to any required under the applicable provisions of Section 74-71 or Section 74-79:
   
   
   1. that the requested departure from the height and setback regulations is the minimum amount necessary to achieve a feasible #building# design;
   
   
   2. that the disadvantages to the surrounding area resulting from reduced light and air access will be more than offset by the advantages of the landmark's preservation to the local community and the City as a whole; and
   
   
   3. that where the landmark is located on the #zoning lot# proposed for #development# or #enlargement# or on a lot contiguous thereto or directly across a #street# therefrom, the modification of height and setback regulations will adequately protect the setting for the landmark.

Center line of the street (bounding a #zoning lot#)

A line equidistant from and parallel or nearly parallel to the #street lines# on both sides of the #street#. However, for the purposes of daylight evaluation:

1. on a #street# 75 feet in width, the #center line of the street# shall be considered to be a line 40 feet from, and parallel to, the #front lot line# of the #zoning lot#; and


2. on a #street# more than 100 feet in width, the #center line of the street# shall be considered to be a line 50 feet from, and parallel to, the #front lot line# of the #zoning lot#.

Daylight Evaluation Chart (DEC)

A graphic tool which permits objective measurements of portions of sky blocked by a #building# when it is viewed from a #vantage point#. There are three #daylight evaluation charts# for use with #street# widths of 60 feet, 75 to 80 feet and 100 feet and over, respectively. All #buildings# are drawn on the appropriate #daylight evaluation chart# to evaluate their compliance with the regulations of Section 81-27 (Alternate Height and Setback Regulations—Daylight Evaluation). These three #daylight evaluation charts# are in Appendix B of this Chapter. A fourth chart in Appendix B is available for use with #qualifying sites# in the East Midtown Subdistrict, as defined in Section 81-613, with frontage along Park Avenue.

Far lot line

A #lot line# intersecting the #street line# of the #vantage street# such that, when viewed from the #vantage point#, the #zoning lot# does not contain any #lot area# that is on the far side of and immediately adjoining the #lot line# at its intersection with the #street line#. (See Illustration of #Far Lot Line# and #Vantage Point#)

FAR LOT LINE AND VANTAGE POINT
                       (81-271.1)

Near lot line

A #lot line#, other than the #far lot line#, which intersects the #street line# of the #vantage street# and which defines the extent of the #zoning lot's# continuous frontage along the #vantage street# from the #far lot line#.

Profile curve

A curved line on the #daylight evaluation chart# rising from the intersection of the curved line representing an elevation angle of 72 degrees with the vertical line at the #far lot line#. The #profile curve# is used to evaluate a #building's# obstruction of the sky as seen in profile from the #vantage point#.

Profile encroachment

The space on the #daylight evaluation chart# which, when viewed from the #vantage point#, is on the far side of the #profile curve# and which is blocked by the projection of the #building# on the #daylight evaluation chart#. (See Illustration of #Profile Encroachment#)

               PROFILE ENCROACHMENT
                               (81-271.2)

Vantage point

A point on the #center line of the street# bounding the #zoning lot# and located 250 feet from the intersection of the extension of the #zoning lot's far lot line# with the #center line of the street#. (See Illustration of #Far Lot Line# and #Vantage Point#)

Vantage street

A #street# bounding the #zoning lot# and on the center line of which a #vantage point# is located.

The #daylight evaluation chart(DEC)# is a graphic representation of a pedestrian's field of view as he or she looks down a #street# and sweeps his or her view 90 degrees to the left or to the right.

Under special conditions, this view can be extended to 180 degrees horizontally as specified in Section 81-275 (Special conditions).

This pedestrian view is based on a #vantage point# located 250 feet from the intersection of the #zoning lot's far lot line# with the #center line of the street#.

There are three #daylight evaluation charts# for use with different Midtown #street# widths. They include a chart for 60- foot wide #streets# (for most east-west crosstown #streets#) as well as a chart for 75-foot or 80-foot wide #streets# and a chart for #streets# 100 feet or more in width (for avenues and major crosstown #streets#). All of these charts have the following features:

1. Horizontal and vertical axes
   
   The #daylight evaluation chart# has both a horizontal and vertical component, encompassing views sweeping both 90 degrees horizontally and 90 degrees vertically. (See Illustration of Horizontal and Vertical Angles of View)
   
   Under special conditions, this view can be extended to 180 degrees horizontally as specified in Section 81-275 (Special conditions).
   
   HORIZONTAL AND VERTICAL ANGLES OF VIEW
                                      (81-272a.1)
   
   The horizontal axis of the #daylight evaluation chart# is measured in degrees of arc from zero degrees to 90 degrees starting from the #vantage point# along the #center line of the vantage street# and sweeping toward the #building#.
   
   The horizontal axis is intersected by vertical lines corresponding to lines of sight from the #vantage point# to points 25 feet apart on the #front lot line# along the #vantage street# measured from the intersection of the #far lot line# with the #vantage street line#.
   
   The vertical axis of the #daylight evaluation chart# is measured in degrees of arc from zero degrees to 90 degrees staring from the #center line of the vantage street# at #curb level# and sweeping upward.
   
   The vertical axis is intersected by curved elevation lines representing elevation angles from the #center line of the street# at 10 degree intervals from zero degrees to 70 degrees and at two degree intervals from 70 degrees to 90 degrees. (See Illustration of Horizontal and Vertical Axes)
   
   
   HORIZONTAL AND VERTICAL AXES
                          (81-272a.2)


2. Daylight squares
   
   The horizontal and vertical lines form a curvilinear grid dividing the #daylight evaluation chart# into areas called daylight squares. Above the 70 degree line, the grid is divided into 100 daylight squares starting from the vertical line rising from the intersection of the #far lot line# with the #street line# of the #vantage street# and ending at the vertical line representing 90 degrees along the horizontal axis. Each of these 100 squares represents 25 feet of lot frontage on the #vantage street# and two degrees of elevation angle from the #center line of the vantage street#.
   
   Below 70 degrees, the grid is divided into 70 daylight squares starting from the vertical line rising from the intersection of the #far lot line# with the #street line# of the #vantage street# and ending at the vertical line rising at 90 degrees along the horizontal axis. Each of these 70 squares represents 25 feet of lot frontage on the #vantage street# and 10 degrees of elevation angle from the #center line of the street#. (See Illustration of Daylight Squares)

              (81-272b)


3. Daylight subsquares
   
   For greater plotting and scoring precision, the horizontal axis of the grid is further subdivided by vertical lines at points five feet apart on the #front lot line# as seen from the #vantage point#. The vertical axis is further subdivided by curved lines representing lines of equal elevation at one degree intervals from 70 degrees to 90 degrees. Therefore, each daylight square is subdivided into ten subsquares, each representing five feet of lot frontage on the #vantage street# and one degree of elevation angle from the #center line of the vantage street#. (See Illustration of Daylight Squares and Subsquares Above 70 Degrees)

                                                    (81-272c)


4. The seventy degree line
   
   Research shows that, as an average, 70 degrees is the elevation angle at which #buildings# in the #Special Midtown District# are set back from the #street line#. Most of the daylight below 70 degrees is blocked by such #buildings#. Slabs, towers or other setback portions of #buildings# rise to block an average of 25 percent of the available daylight squares above 70 degrees.
   
   In #building# evaluation, the #DEC# measures the blocked sky above 70 degrees. Below 70 degrees, #buildings# are given credit for unblocked daylight.


5. The #profile curve#
   
   The grid is traversed by the #profile curve#, which rises from the intersection of the curved line representing an elevation angle of 72 degrees with the vertical line at the #far lot line#. The #profile curve# is derived from the predominant built character of developed Midtown #streets# as seen in profile. #Encroachment# across the #profile curve# is penalized to discourage canyon-like Midtown #streets# and to protect neighboring #buildings#.

Evaluation of a #development# or #enlargement# requires drawing the new #buildings#, remaining #buildings# and open areas on the #zoning lot# on the appropriate #daylight evaluation chart#, as viewed from each required #vantage point# and then scoring the #zoning lot#. The rules for plotting #buildings# on the #DEC# are set forth in the following paragraphs of this Section and illustrated by an example of a #building# which fronts on a 100 foot wide #street# and occupies a site 170 feet long by 100 feet deep.

1. Draw the #building#
   
   Draw the #building# in plan showing all #street# frontages of the #zoning lot#. Draw the #building# in section perpendicular to each #street# on which the #zoning lot# fronts. On both plan and section drawings label all corners of the #building#. In the example they are labeled corners (a) through (h). (See Illustrations of Example: Building Drawings)
   
   EXAMPLE: BUILDING DRAWINGS
                      (81-273a)


2. Establish #vantage points#
   
   Establish on the plan all the #vantage points# from which views must be taken. #Vantage points# shall be established on the #center line of the vantage street# 250 feet from the intersection of the #zoning lot's far lot line# and the #center line of the street#. For each #vantage street# there are at least two #vantage points#. In the example, they are V1 and V2. For each #vantage point# there shall be a separate #daylight evaluation chart#. The example will use #vantage point# one.


3. Record plan and section dimensions
   
   Record on a coordinate chart for each corner of the #building# the following dimensions:
   
   
   1. Dimensions in plan:
      
      The distance (S) between the corner and the #center line of the street# as measured along a line that intersects the #center line of the street# at right angles. In the example, distance (S) of corner (b) + 50 feet.
      
      The distance (D) measured along the #center line of the street# from the #vantage point# to the point where the #street# center line is intersected by the perpendicular line from the corner. In the example, distance (D) of corner (b) + 250 feet.
   
   
   2. Dimension in section:
      
      The height (H) of the corner above #curb level#. In the example, height (H) of corner (b) + 140 feet.


4. Calculate plan and section angles
   
   Determine the plan and section angles for each corner of the #building# as viewed from the #vantage point#.
   
   
   1. A plan angle is an angle on the plan formed at the #vantage point# by the line of sight to a corner of the #building# and the #center line of the vantage street#. The plan angle is found by calculating the tangent. The tangent is the quotient found by dividing distance (S) by distance (D). The plan angle for the resulting tangent is found in a tangent table and is then entered on the coordinate chart in the column marked "plan angles."
   
   
   2. The section angle is an angle formed by a line representing the distance in section from a corner of the #building# to the #center line of the vantage street# and a line representing the distance in plan (S) between the corner and the #center line of the street#. The section angle is found by calculating its tangent. The tangent is the quotient obtained by dividing the height of the corner (H) by its horizontal distance (S) from the #center line of the street#.
      
      The section angle for the resulting tangent is found in a tangent table and is then entered on the coordinate chart in the column market "section angles."

      g & h	23	150	23/150 = 0.15	8.7o



5. Plot corner coordinates
   
   Plot each corner of the #building# onto the #daylight evaluation chart# at the point where the coordinates for that corner intersect. The plan angle coordinates are found on the horizontal axis of the chart and the section angle coordinates are found on the vertical axis. The points plotted are then connected to represent the edges of the #building# as shown on the plan and section drawings. A connecting line parallel to the #vantage street line# is drawn as a curve parallel to the closest elevation line. A connecting line perpendicular to the #vantage street line# is drawn parallel to the closest dotted elevation line, which is perpendicular to the #street#. A connecting line which is neither parallel nor perpendicular to the #vantage street# is approximated on the chart by:
   
   
   1. establishing points along the line in plan at 10 foot intervals;
   
   
   2. finding the coordinates of the points and plotting them on the chart; and
   
   
   3. connecting the resulting points.
   
   The connecting lines produce a curvilinear perspective drawing of the #building# as seen from the #vantage point# projected onto the #daylight evaluation chart#. Since in the example #vantage point# one is on a 100 foot wide #street#, corner coordinates are plotted on a #daylight evaluation chart# for 100 foot wide #streets#. In the example, corner (b) is at the intersection of plan angle 11.3^o and section angle 70.3^o(See Illustration of Building as Drawn on the Daylight Evaluation Chart)
   
   BUILDING AS DRAWN ON THE DAYLIGHT EVALUATION CHART
                                                    (81-273e)


6. Determine daylight boundaries
   
   Draw a vertical line on the chart rising from the intersection of the #near lot line# of the #zoning lot# with the center line of the #block# or with a line 100 feet distant from and parallel to the #front lot line# on the #vantage street#, whichever line is closer to the #vantage street#. This line and the #far lot line# represent the boundaries of the potential sky area that the #building# could block. (See Illustration of Building as Drawn on the Daylight Evaluation Chart)

A #zoning lot# is scored by determining the number and the value of the daylight squares the #building# blocks when viewed from the #vantage point#, compared to the total number of daylight squares available within the daylight boundaries as determined in paragraph (f) of Section 81-273 (Rules for plotting buildings on the daylight evaluation chart) and above an elevation angle of 70 degrees.

1. Assign daylight values
   
   The daylight squares on the #daylight evaluation chart# are each assigned a value.
   
   
   1. Except along #vantage streets# designated for #street wall# continuity (see Section 81-43), each unblocked daylight square below the curved line representing an elevation of 70 degrees has a positive value of 0.3 and each unblocked subsquare below the same curved line has a positive value of 0.03.
   
   
   2. Each blocked daylight square above the curved line representing an elevation of 70 degrees has a negative value of 1.0.
   
   
   3. Where a #building# blocks any portion of a subsquare the #building# is charged with blocking the entire subsquare in computing the daylight evaluation score. Each blocked subsquare has a negative value of 1.0/10 or 0.1.
   
   
   4. The daylight squares and subsquares which are on the far side of the #profile curve# are assigned additional weighted values set forth on the chart below. (See Illustration of #Profile Encroachment# Incurring Profile Penalty)
      
      

      Degrees of Elevation	Distance from #Far Lot Line#
      	1st 25ft	2nd 25ft	3rd 25ft	4th 25ft	5th 25ft	6th 25ft	7th 25ft	8th 25ft
      88-90	8.5	8.0	7.5	7.0	6.5	6.0	5.5	5.0
      86-88	7.5	7.0	6.5	6.0	5.5	5.0	4.5	4.0
      84-86	6.5	6.0	5.5	5.0	4.5	4.0	3.5	-
      82-84	5.5	5.0	4.5	4.0	3.5	3.0	2.5	-
      80-82	4.5	4.0	3.5	3.0	2.5	2.0	1.5	-
      78-80	3.5	3.0	2.5	2.0	1.5	1.0	-	-
      76-78	2.5	2.0	1.5	1.0	.5	-	-	-
      74-76	1.5	1.0	.5	.5	-	-	-	-
      72-74	.5	.5	.5	-	-	-	-	-

      
      
      PROFILE ENCROACHMENT INCURRING PROFILE PENALTY
                                                       (81-274a)
   
   
   5. If the #building# encroaches beyond the #profile curve#, the entire subsquare in which the #encroachment# is located is given an additional weighted value. The total penalty is the additional weighted value of the daylight square multiplied by the negative value of the subsquare. The penalty is applied even if the subsquare does not lie entirely beyond the curve.


2. Calculate daylight blockage
   
   Count the number of blocked daylight squares and subsquares which are above the curved line representing an elevation of 70 degrees. A negative sign is to be given to this number. Total value of daylight blockage in the example is -20.5.


3. Calculate unblocked daylight credit
   
   Count the number of unblocked daylight squares which are below the curved line representing an elevation of 70 degrees and within the area defined by the intersection of the #far lot line# with the #vantage street line# and the intersection of the #near lot line# with the #vantage street line#. The total is given a positive value and multiplied by 0.3, the value of these daylight squares. This provision is not applicable where the #vantage street# is a designated #street# on which #street wall# continuity is required by the provisions of Section 81-43 (Street Wall Continuity along Designated Streets). In the example, the number and value of squares unblocked below 70 degrees = +0.0.
   
   


4. Calculate profile daylight blockage
   
   Count the number of blocked daylight squares which are entirely on the far side of the #profile curve# when viewed from the #vantage point# and the number of blocked or partially blocked subsquares which are on the far side of the #profile curve#. All of these daylight squares and subsquares are given a negative sign, multiplied by their respective weighted values in the table in paragraph (a)(4) of this Section and the products added. Subsquares are counted as one tenth of a daylight square. In the example, the total value of profile daylight blockage = -0.45.


5. Calculate available daylight
   
   Count the number of daylight squares available to the site. This is the total number of daylight squares and subsquares, calculated to the nearest tenth, that are above the curved line representing the boundaries of the potential sky area available to the site, said boundaries being delineated in accordance with the provisions of paragraph (f) of Section 81-273 (Rules for plotting buildings on the daylight evaluation chart). Available daylight in the example is 89.9.


6. Calculate daylight remaining
   
   Calculate the remaining or unblocked daylight by adding the results of paragraphs (b) through (e) of this Section. Daylight remaining in the example is (-20.5) + (0.0) + (-0.45) + (89.9) = 68.95.


7. Calculate daylight score
   
   Compute the remaining daylight score from paragraph (f) of this Section, as a percentage of the available daylight from paragraph (e) of this Section. The percentage is the daylight score for the proposed #building# from that #vantage point#. In the example, the daylight score is 68.95/89.9 = 76.70 percent for #vantage point# one (V1).


8. Calculate overall daylight score
   
   1. The street score is the arithmetic mean of all the scores from all #vantage points# along a #vantage street#. When a #zoning lot# fronts on only one #street#, the street score is also the overall score. Where a #zoning lot# has more than one #street# frontage along any one #vantage street#, the street score is the average of all those individual #street# frontage scores computed pursuant to paragraph (b) of Section 81-275 (Special conditions), weighted by the lengths of all those #street# frontages.
   
   
   2. Where a #zoning lot# fronts on more than one #street#, the overall score is the average of the street scores, weighted by the length of their respective #vantage street# frontages.


9. The passing score
   
   To be in compliance with these regulations, a #zoning lot# must have an overall score of not less than 75 percent, with no single #street# frontage having a street score of less than 66 percent. If a #zoning lot# fronts only on one #street#, a daylight evaluation score of not less than 75 percent is required for that #street# frontage. If a street score is less than 66 percent, or if the overall daylight score is less than the passing score of 75 percent, a modest improvement in either the street score or the overall score may be obtained by scoring the relative reflectivity of the #building's# surface, as specified in Section 81-276 (Modification of score for reflectivity). The passing daylight score of 75 percent is equivalent to the average daylight levels of Midtown #buildings# built as-of-right under the 1916 and 1961 Zoning Resolutions. The minimum requirement of 66 percent on one frontage is equivalent to the daylight level of any #interior lot building# built in Midtown under the 1916 Zoning Resolution in a two-times height district. However, if any one frontage is less than 75 percent, other frontages must be greater than 75 percent to reach the passing overall daylight score. This allows flexibility in #building# design while maintaining daylight standards within the levels established by #buildings# built as-of-right under the 1916 and 1961 Zoning Resolutions. (See Illustration of Daylight Evaluation Score Results)
   
   
   DAYLIGHT EVALUATION SCORE RESULTS
                                (81-274i)

Notwithstanding the provisions of Sections 81-271 to 81-274, inclusive, relating to Alternate Height and Setback Regulations-Daylight Evaluation, the provisions of this Section shall apply under special conditions, as follows:

1. For #zoning lots# with #street# frontages exceeding 250 feet
   
   
   1. Where the length of the #street# frontage is more than 250 feet but not more than 500 feet, the #building# as viewed from each #vantage point# shall be plotted on a #daylight evaluation chart# that extends in both directions from the 90 degree line on the horizontal axis. In each case, the number of available daylight squares for daylight evaluation shall be the number of squares between the #far lot line# and the #near lot line#.
   
   
   2. Where the length of the #street# frontage is more than 500 feet, daylight evaluations shall be made from three #vantage points#, as follows: #vantage points# one and two, each 250 feet distant from a #far lot line# extended to the #center line of the street#, and #vantage point# three, on the #center line of the street#, half-way between the other two #vantage points#. The #daylight evaluation charts# for the first two #vantage points# shall in each case encompass a view extending from the #far lot line# to the 90 degree line on the horizontal axis and the number of available daylight squares shall be the number of squares between the #far lot line# and the 90 degree line and above the curved line representing an elevation angle of 70 degrees. The #daylight evaluation chart# for the third #vantage point# shall extend in both directions from the 90 degree line on the horizontal axis to the vertical lines representing the points on the #front lot line# directly opposite #vantage points# one and two. The number of available daylight squares for daylight evaluation shall be the number of daylight squares between such vertical lines and above the curved line representing an elevation angle of 70 degrees.


2. For #zoning lots# with interrupted #street# frontages
   
   Where a #zoning lot# has two or more #front lot lines# on the same #street# which are separated by frontage of an intervening #zoning lot#, there shall be two daylight evaluations for each such #front lot line#. Each #lot line# of the #zoning lot# that intersects the #street line# shall be treated as a #far lot line# for the purposes of daylight evaluation from a #vantage point#.


3. Where #front lot lines# are curved or broken
   
   If the #front lot line# of the #zoning lot# is curved or bent, the extremities of such #front lot line# shall be connected by a straight line, which shall be considered the #front lot line#.

Where #zoning lots# have utilized the #daylight evaluation chart# but a street score along one frontage is less than 66 percent or the overall score is less than 75 percent, a modest improvement in either the street score or the overall score of a #zoning lot# within a #building# which reflects more light than a medium gray or glass #building# may be obtained by scoring the relative reflectivity of the #building's# surface.

The use of reflectivity is optional and not necessary if a passing score can be obtained under Section 81-274 (Rules for determining the daylight evaluation score). Reflectivity scoring permits greater design flexibility for a light-colored #building# than a dark one.

Because the greatest reflectivity comes from the upper portions of #buildings#, the value of reflected light is credited against the amount of daylight blocked by the portions of the #building# above an elevation angle of 70 degrees from the #center line of the street#.

Reflectivity has two components: the reflectance of the surface material and the orientation of the material to the sun.

1. Reflectance
   
   Reflectance values of materials will be determined by the Department of Buildings after the submission of samples of proposed surface materials by the applicant.
   
   
   1. Mixed reflectance
      
      A #building# of several surface materials will have a reflectance value determined by multiplying each material's reflectance value by its percentage of the total wall surface and adding the products. For example, a #building# that is 60 percent limestone and 40 percent clear glass would have a reflectance of .60 x .45 (the reflectance of limestone) plus .40 x .15 (the reflectance of clear glass) or an overall reflectance of .33
   
   
   2. Relative reflectance
      
      In order to be included in the reflectivity score of a #zoning lot#, the material of the #building# must reflect more light than a medium gray or glass #building#. The reflectance value of a medium gray or glass #building# in Midtown is .15 so that the #building# with an overall reflectance of .33, given in the example in paragraph (a)(1) of this Section, would be increasing the expected reflectance by .33 minus .15 which equals .18.
      
      Examples of potential reflectance values for different types of surface finishes are shown on the following chart.

      Reflectance varies according to which layer the reflective coating is placed on, but can be precisely determined for each position Sources: Anderson, Bruce.

2. Facade orientation
   
   Orientation of the facade of the #building# is the second component required for measurement of reflectivity. Because reflectivity varies according to the orientation of the facade, the orientation value for a particular surface from the chart below is multiplied by the reflectance of the surface to ascertain the amount of daylight reflectivity.
   
   The orientation values are shown on the following reflectivity chart. Orientation angles shall be rounded to the nearest 22.5 degrees.
   
   

   Orientation based on True North		Orientation Value

   	22.5o	.15
   	45.0o	.22

   East:	90.0o	.57
   	112.5o	.72
   	135.0o	.87

   West:	90.0o	.57
   	67.5o	.40
   	45.0o	.22
   	22.5o	.15





3. Reflectivity Score
   
   In order to obtain the reflectivity score for each view of the #building#, first count the daylight squares and subsquares which are blocked by the #building# on the #daylight evaluation chart# above an elevation angle of 70 degrees. This number shall be calculated separately for every orientation of each facade and multiplied by the relative reflectance of that portion of the #building# and the orientation value.
   
   Reflectance = (% material A x reflectance material A) + (% material B x reflectance material B)
   
   Relative reflectance (RR) = reflectance minus .15
   
   Reflectivity score = RR x facade orientation value x daylight
   

The reflectivity scores for the several orientations are then added together to give the reflectivity score for that view of the #building# as a whole from the #vantage point# represented on the #daylight evaluation chart#.
The reflectivity score is added to the daylight remaining after accounting for daylight blockage as calculated in paragraph (f) of Section 81-274 (Rules for determining the daylight evaluation score).
The sum is then calculated as a percentage of the available daylight squares calculated in paragraph (e) of Section 81-274 to give the adjusted daylight score for the #zoning lot# from the #vantage point# represented on the #daylight evaluation chart#.
The adjusted street score along a particular #vantage street# is obtained by calculating the mean average of the adjusted daylight scores from all #vantage points# along the #vantage street#.
The adjusted overall score for the #zoning lot# is obtained by calculating the average of the adjusted street scores weighted by the lengths of their respective #vantage street# frontages.

Limits on adjusted scores

1. Adjusted street score
   
   The adjusted street score shall not be more than six percentage points higher than the street score not adjusted for reflectivity.
   
   If reflectivity scoring is used to bring the adjusted overall score for the #zoning lot# above 75 percent (the passing overall score), the street score for each #street# frontage without adjustment for reflectivity shall be not less than 66 percent.


2. Adjusted overall score
   
   The adjusted overall score shall not be more than six percentage points higher than the overall score not adjusted for reflectivity.
   
   If the reflectivity scores for any single #street# frontage are used to bring the adjusted street score for that frontage above 66 percent (the passing score for a single #street# frontage), the overall score of the #zoning lot# without adjustment for reflectivity shall be not less than 75 percent.

In C5-3, C6-6 or C6-7 Districts, where a special permit application is made pursuant to Section 74-71 (Landmark Preservation) for modification of #bulk# regulations on a #zoning lot# containing a landmark, or where a special permit application is made pursuant to Section 74-79 (Transfer of Development Rights from Landmark Sites) and the #floor area# represented by such transferred development rights exceeds 20 percent of the basic maximum #floor area# permitted on the #zoning lot# receiving the development rights, such application may include a request for modification of the height and setback regulations set forth in Sections 81-261 to 81-275, inclusive, relating to Alternate Height and Setback Regulations - Daylight Evaluation. The City Planning Commission may authorize such height and setback modifications subject to the following conditions:

1. The applicant shall demonstrate to the satisfaction of the Commission that a feasible design for the proposed #development# or #enlargement# which accommodates the permitted #floor area# is not possible under the provisions of Sections 81-271 to 81-276, inclusive, and shall further present for the proposed design a complete daylight evaluation with an explanation of street score or overall daylight score deficiencies.


2. The Commission shall make the following findings in addition to any required under the applicable provisions of Sections 74-71 or 74-79:
   
   
   1. that the requested departure from the alternate height and setback regulations is the minimum amount necessary to achieve a feasible #building# design;
   
   
   2. that the disadvantages to the surrounding area resulting from reduced light and air access will be more than offset by the advantages of the landmark's preservation to the local community and the City as a whole; and
   
   
   3. that where the landmark is located on the #zoning lot# proposed for #development# or #enlargement# or on a lot contiguous thereto or directly across a #street# therefrom, the modification of the alternate height and setback regulations will adequately protect the setting for the landmark

On any single #zoning lot# within the #Special Midtown District#, if two or more #buildings# or portions of #buildings# are detached from one another at any level, such #buildings# or portions of #buildings# shall at no point be less than eight feet apart.

The City Planning Commission may grant special permits authorizing, for #non-residential# or #mixed buildings#, #floor area# bonuses in accordance with the provisions of this Section.

Except in the Preservation Subdistrict and except for #zoning lots# wholly within the Theater Subdistrict Core, as defined in Section 81-71 (General Provisions), the City Planning Commission may grant special permits for #floor area# bonuses for #non-residential# or #mixed buildings#, in accordance with the provisions of Section 74- 634 (Subway station improvements in Downtown Brooklyn and in Commercial Districts of 10 FAR and above in Manhattan).

The subway stations where such improvements are permitted are listed in the following table and shown on Map 3 (Subway Station and Rail Mass Transit Facility Improvement Areas) in Appendix A of this Chapter.

The regulations of Article I, Chapter 3 (Comprehensive Off-Street Parking and Loading Regulations in the Manhattan Core), and the applicable underlying district regulations of Article III, Chapter 6, or Article IV, Chapter 4, relating to Off-Street Loading Regulations, shall apply throughout the #Special Midtown District#, except as otherwise provided in this Section.

Notwithstanding the provisions of Article I, Chapter 3, prohibitions of off-street parking facilities or #accessory# off-street loading berths or restrictions as to their location or access, as provided in Sections 81-44 (Curb Cut Restrictions) or 81-84 (Mandatory Regulations and Prohibitions), may be waived only in accordance with the applicable provisions of Sections 81-44 or 81-84.

The provisions of Section 81-40 (MANDATORY DISTRICT PLAN ELEMENTS) specify mandatory planning and urban design features. Requirements which apply generally or with minor specified exceptions throughout the #Special Midtown District# are fully set forth in the provisions of Section 81-40. For requirements which are not generally applicable but tied to specific locations within the District, the locations where these requirements apply are shown on Map 3 (Retail and Street Wall Continuity) or Map 4 (Subway Station and Rail Mass Transit Facility Improvement Areas) in Appendix A of this Chapter.

The provisions of Section 81-40 are all primarily oriented toward the accommodation and well-being of pedestrians. The requirements pertain to a number of elements which are interrelated and complement one another but are set forth in different sections because they can be treated separately. Sections 81-42 (Retail Continuity Along Designated Streets), 81-43 (Street Wall Continuity Along Designated Streets) and 81-44 (Curb Cut Restrictions) are a group of sections with closely related purposes concerned with amenity and the well-being and safety of pedestrians. Sections 81-45 to 81-48, inclusive, are all concerned primarily with pedestrian traffic circulation. Major #building# entrances are focal points of heavy pedestrian traffic, so that controls on the locations of these entrances, as set forth in Section 81-48, are closely related to the pedestrian circulation space requirements.

Special district plan requirements for the Penn Center Subdistrict are set forth in Section 81-50, for the East Midtown Subdistrict are set forth in Section 81-60, for the Theater Subdistrict are set forth in Section 81-70, for the Fifth Avenue Subdistrict are set forth in Section 81-80 and for the Preservation Subdistrict are set forth in Section 81-90.

Owners of property on which pedestrian circulation spaces are provided shall be responsible for their maintenance unless, in the case of relocated subway stairs, the Metropolitan Transit Authority has agreed in writing to such maintenance responsibility.

Directional #signs# are required to call attention to relocated subway stairs and through #block# connections and announce their accessibility to the public.

All mandatory district plan elements required by the provisions of Section 81-45 (Pedestrian Circulation Space) shall conform with applicable laws pertaining to access for persons with disabilities.

For #buildings developed# or #enlarged# after May 13, 1982, where the ground floor level of such #development# or #enlarged# portion of the #building# fronts upon a designated retail #street# (see Appendix A, Map 3), #uses# within #stories# on the ground floor or with a floor level within five feet of #curb level# shall be limited to retail, personal service or amusement #uses# permitted by the underlying zoning district regulations but not including #uses# in Use Groups 6B, 6E, 7C, 7D, 8C, 8D, 9B, 10B, 11 and 12D or automobile showrooms or plumbing, heating or ventilating equipment showrooms. Museums and libraries shall be permitted. A #building's street# frontage shall be allocated exclusively to such #uses#, except for:

1. lobby space or entrance space;


2. entrance areas to subway station improvements for which bonus #floor area# is granted and #street wall# continuity restrictions waived pursuant to Sections 74-634 (Subway station improvements in Downtown Brooklyn and in Commercial Districts of 10 FAR and above in Manhattan) and 81-292 (Subway station improvements);


3. one or more of the following pedestrian circulation spaces subject to the #street wall# continuity requirements of Section 81-43 (Street Wall Continuity Along Designated Streets):
   
   
   1. relocated subway stairs provided in accordance with Sections 37-40 and 81-46 (Off-street Relocation or Renovation of a Subway Stair);
   
   
   2. through #block# connections provided in accordance with paragraph (h) of Section 37-53 (Design Standards for Pedestrian Circulation Spaces); and
   
   
   3. off-street improvements of access to rail mass transit facilities provided in accordance with Section 81-48 (Off-Street Improvement of Access to Rail Mass Transit Facility).

Except as provided in the following sentence, in no event shall the length of #street# frontage occupied by lobby space, entrance space and/or a #building# entrance recess exceed the lesser of 40 feet or 25 percent of the #building's# total #street# frontage exclusive of any frontage occupied by a relocated subway stair, a through #block# connection, an off-street improvement of access to rail mass transit facility or the entrance area to a bonused subway station improvement. However, the total length of #street# frontage occupied by lobby space and/or entrance space need not be less than 20 feet.

Storefronts for the permitted ground floor #uses# shall be not more than 10 feet from the #street line# or, where an arcade is provided with supporting columns at the #street line#, not more than 10 feet from the supporting columns.

Access to each retail, personal service or amusement establishment required under this Section shall be provided directly from the designated retail #street#. Where more than one entrance is provided to the establishment, direct access from the designated retail #street# shall be provided via the entrance with the greatest aggregate clear opening width. At least 50 percent of the #street wall# surface of each required establishment shall be glazed with clear untinted transparent material and not more than 50 percent of such transparent surface shall be painted or obstructed with #signs#. For the purpose of this glazing requirement, the establishment's #street wall# surface shall be measured from the floor to the height of the ceiling or 14 feet above grade, whichever is less.

Special #use# regulations apply along designated retail #streets# located within the boundaries of the Penn Center Subdistrict, the East Midtown Subdistrict, the Theater Subdistrict or the Fifth Avenue Subdistrict and #uses# along such designated #streets# shall be subject to the respective subdistrict retail requirements in Sections 81-531, 81-674, 81-72 and 81-82.

Special ground level and entertainment-related #use# regulations apply to #zoning lots# located within the Theater Subdistrict Core, as defined in Section 81-71 (General Provisions), and such #zoning lots# shall meet the ground level and entertainment-related #use# requirements of Section 81-72 (Use Regulations Modified).

On designated #streets# where #street wall# continuity is required (see Map 2 in Appendix A) and, between 43rd and 50th Streets, on the #narrow street# frontages of #zoning lots# with #street# frontage on Seventh Avenue and/or Broadway, the #street wall# of a #building#, for the minimum width and height set forth in this Section, shall be within 10 feet of the #street line# or within 10 feet of a permitted arcade’s supporting columns at the #street line#, except that on 57th Street, 42nd Street, 34th Street and Fifth Avenue, no #street wall# setback below a height of 85 feet is permitted. The width of the #street wall# subject to setback restrictions shall be at least 80 percent of the length of the #front lot line# of the #zoning lot# along the specified #street#, measured at the specific heights or anywhere above the specific heights indicated in the table in this Section. At those specific heights or anywhere above those specific heights, the #street wall# must extend continuously within 10 feet of the #street line# for all of its required width, except that on 57th Street, 42nd Street, 34th Street and Fifth Avenue, at a height of 85 feet or above, the #street wall# must extend continuously without setback for at least 75 percent of its required width and no portion of its required width shall be set back more than 10 feet from the #street line#; and, for #zoning lots# between 43rd and 50th Streets with #street# frontage on Seventh Avenue and/or Broadway, any portion of the required width of a #street wall# which lies behind a #sign# required under the provisions of Section 81-732 (Special Times Square signage requirements) may be set back up to 15 feet from the #street line#.

The minimum height of a #street wall# subject to the setback restrictions shall be as follows:

Length of #Zoning Lot# Frontage	Minimum Height of a #Street Wall# Subject to the Setback Restrictions
For #zoning lots# with frontages of 50 feet or less on the designated #street#	Four #stories# or 50 feet above #curb level#, whichever is less
For #zoning lots# with frontages of more than 50 feet on the designated #street#	Six #stories# or 85 feet above #curb level#, whichever is less

#Developments#, which are in their entirety no more than two #stories# in height, shall be exempt from the minimum #street wall# height requirements set forth in the table in this Section, except that, subsequent to the issuance of a building permit for such #development#, if there are additional #developments# on the #zoning lot# or if any #building# on the #zoning lot# is #enlarged#, the #development# exempt from the requirements set forth in the table in this Section, shall no longer be exempt from such requirements and its #street walls# shall be raised to a height complying with the table.

Existing #buildings# need not comply with the minimum #street wall# height and location provisions of this Section. Such #buildings# shall be included in the calculation of the required percentage of #street wall# width and height along a #street# frontage. No existing #building# shall be altered such that a #non-compliance# with the provisions of this Section is created, nor shall an existing degree of #non-compliance# with these provisions be increased.


STREET WALL REQUIREMENT WITH EXISTING BUILDING
                                         (81-43)

Pedestrian circulation spaces may be provided to meet the requirements of Sections 81-45 (Pedestrian Circulation Space), 81-46 (Off-street Relocation or Renovation of a Subway Stair) or 81-48 (Off-street Improvement of Access to Rail Mass Transit Facility), subject to the setback restrictions of this Section and to the minimum width of the #street wall# subject to such setback restrictions. However, the City Planning Commission may waive such restrictions for a subway entrance area which is part of a subway station or a rail mass transit facility improvement for which bonus #floor area# is granted, in accordance with the provisions of Sections 74-634 (Subway station improvements in Downtown Brooklyn and Commercial Districts of 10 FAR and above in Manhattan), 81-292 (Subway station improvements) and 81-542 (Retention of floor area bonus for plazas or other public spaces), or an off-street improvement of access to a rail mass transit facility that has been certified in accordance with Section 81-48.

Except on 57th Street, 42nd Street, 34th Street and Fifth Avenue, below the minimum height of a #street wall# subject to the setback restriction, recesses (whose depth shall be measured in all cases from the #street line#) shall be permitted only as follows: no recesses greater than 15 feet deep shall be permitted, recesses up to 15 feet deep shall be limited in their aggregate area to no more than 30 percent of the area of the new #street wall# below the minimum required #street wall# height; in addition, recesses up to 12 feet deep shall be limited in their aggregate area to no more than 20 percent of the area of the #street wall# below the minimum required #street wall# height, and recesses up to 10 feet deep shall not be limited in their aggregate area.

On 57th Street, 42nd Street, 34th Street and Fifth Avenue, below the minimum height of a #street wall# subject to the setback restriction, recesses (whose depth shall be measured in all cases from the #street line#) shall be permitted only as follows: no recesses greater than 10 feet deep shall be permitted; recesses up to 10 feet deep shall be limited in their aggregate area to no more than 30 percent of the area of the #street wall# below the minimum required #street wall# height; in addition, recesses up to two feet deep shall be limited in their aggregate area to no more than 20 percent of the area of the #street wall# below the minimum required #street wall# height and recesses up to one foot deep shall not be limited in their aggregate area.

The restrictions on recesses shall not apply to arcades, corner arcades, subway stairs relocated within the #building#, through #block# connections within the #building# or #building# entrance recess areas within the #building#, where such spaces are provided in accordance with the requirements and design standards of Sections 81-45 or 81-46 and provided that such spaces shall be subject to a maximum height limit of 30 feet. Any recesses in the #residential# portion of a #building# shall comply with the #outer court# regulations of Section 23-84.

No arcades, sidewalk widenings or #public plazas# shall be permitted on Fifth Avenue, 34th Street, 42nd Street or 57th Street frontages.

Between 42nd and 56th Street, no arcades or #public plazas# shall be permitted on Eighth Avenue. Between 43rd and 50th Streets, no arcades or #public plazas# shall be permitted on Seventh Avenue or Broadway and, with the exception of marquees and #signs#, any area between the Seventh Avenue or Broadway #street line# and any required #street wall# below the height of the first required setback, including permitted recesses, shall be open from #curb level# to the sky in its entirety. Any such area shall be at the same elevation as the adjoining sidewalk, directly accessible to the public at all times and free of all obstructions at ground level, including #street# trees. On the remaining #streets# designated for #street wall# continuity, arcades, if provided, shall be not less than 10 feet in depth and not more than 30 feet high. Arcades shall not be counted toward the recess allowances.

For #zoning lots# between 43rd and 50th Streets with #street# frontage on Seventh Avenue and/or Broadway, the minimum and maximum heights of #street walls# subject to the setback restrictions on all #street# frontages shall be in accordance with Section 81-75 (Special Street Wall and Setback Requirements).

For #zoning lots# located wholly or partially within the Eighth Avenue Corridor, the minimum and maximum heights of #street walls# subject to the setback restrictions on all #street# frontages shall be in accordance with Section 81-75.

On Fifth Avenue, the minimum required #street wall# height without setback shall be 85 feet and the maximum allowable #street wall# height without setback shall be 125 feet. Above the maximum #street wall# height, a setback of at least 10 feet shall be required, pursuant to the provisions of Section 81-83.

Along all avenues in Midtown and along 57th, 53rd, 42nd and 34th Streets, no driveway curb cuts for parking facilities or loading berths shall be permitted except for the following:

1. the Commissioner of Buildings may approve a curb cut where there are no alternative means of access to off-street loading berths from other #streets# bounding the #zoning lot#; or


2. the City Planning Commission may authorize curb cuts where such curb cuts are needed for required loading berths. Such loading berths must be adjacent to a fully enclosed maneuvering area on the #zoning lot# at least equal in area to the area of the required loading berth and arranged so as to permit head-in and head-out truck movements to and from the #zoning lot#. The City Planning Commission will refer such applications to the Department of Transportation for their comment.

In addition, for #zoning lots# with frontage along such avenues and #streets# in Midtown where curb cuts are prohibited, the Commissioner of Buildings may waive required off-street loading berths pursuant to the provisions set forth in Section 13-35 (Modification of Loading Berth Requirements).

Where a curb cut is permitted as indicated in this Section, the maximum width of such curb cut shall be 15 feet for one-way traffic and 25 feet for two-way traffic. These curb cut requirements shall be in addition to any other applicable City rules or regulations concerning driveway curb cuts.

The above exceptions do not apply to Fifth Avenue, or between 43rd and 50th Streets, to Seventh Avenue or Broadway and no curb cuts shall be permitted in these cases. Between 43rd and 50th Streets, access to #accessory# off-street loading berths or off-street parking facilities shall not be permitted on Seventh Avenue or Broadway or, except where the length of a #narrow street block# frontage between the #street lines# of Seventh Avenue and Broadway exceeds 75 feet but is less than 125 feet, within 50 feet of the Seventh Avenue or Broadway #street line#. #Interior lots# between 43rd and 50th Streets with a #street# frontage only on Seventh Avenue or Broadway shall not contain loading berths.

Within the #Special Midtown District#, all #developments# or #enlargements# constructed after May 13, 1982, on #zoning lots# of 5,000 square feet or larger with more than 70,000 square feet of new #floor area#, shall provide pedestrian circulation space on such #zoning lot# in accordance with the provisions of Section 37-50, as modified by the provisions of this Section.

The requirements for pedestrian circulation space may be met by providing one or more of the following types of spaces: arcade, #building# entrance recess area, corner arcade, corner circulation space, relocation or renovation of a subway stair, sidewalk widening, subway station improvement, through #block# connection or #public plaza#.

In addition to the types of pedestrian circulation spaces listed in Section 37-50, the following may be counted toward meeting the minimum pedestrian circulation space requirement:

1. up to a maximum of 3,000 square feet of an access improvement to rail mass transit provided pursuant to Section 81-48 (OffStreet Improvement of Access to Rail Mass Transit Facility);


2. within the Theater Subdistrict, theater waiting space provided pursuant to Section 81-451 (Theater waiting space).

However, pedestrian circulation space shall not be required if any of the following conditions exist:

1. the #zoning lot# is entirely occupied by a #building# of no more than one #story# in height;


2. the #zoning lot# is an #interior lot# fronting on a #wide street# with less than 80 feet of #street# frontage;


3. the #zoning lot# is an #interior# or #through lot# fronting only on a #street# or #streets# where arcades, sidewalk widenings or #public plazas# are prohibited;


4. the #zoning lot# is an #interior lot# fronting on either 34th Street, 42nd Street, 57th Street or Fifth Avenue, with another interior frontage of lesser length on any other #street#; or


5. the #zoning lot# is a #through lot# with both #street# frontages less than 25 feet in length.

#Developments# or #enlargements# on a #zoning lot# having a full #block# frontage on a #wide street# other than Fifth Avenue, 34th Street, 42nd Street or 57th Street shall provide a minimum of 50 percent of their required pedestrian circulation space on that #street#. In the case of a #zoning lot# having two full #block# frontages on #wide streets#, this minimum amount may be allocated on either one or both #wide streets#; where each #street# bounding a #zoning lot# with at least one full #block# frontage is a #wide street#, the minimum amount may be allowed on one or more of those #wide streets#.

Where pedestrian circulation space is provided along Seventh Avenue or Broadway between 43rd and 50th Streets, #signs# and marquees shall be permitted as exceptions to the requirements relating to permitted obstructions in Section 37-50.

Special dimensional requirements for arcades and sidewalk widenings along designated #streets# are set forth in Section 37-53 (Design Standards for Pedestrian Circulation Spaces). Where a new #building# or #enlarged# portion of an existing #building# provides an arcade, no obstructions, including columns, shall be permitted within such arcade, and the maximum height of such arcade shall be 20 feet and the maximum width shall be 10 feet. Arcades or sidewalk widenings shall not be permitted on 34th Street, 42nd Street, 57th Street or Fifth Avenue frontages or on any #street# frontage within the Preservation Subdistrict. Between 43rd and 50th Streets, no arcades shall be permitted parallel to and along Seventh Avenue or Broadway.

Theater waiting space shall be an unobstructed area providing outdoor waiting space for a theater audience, located immediately adjacent to the sidewalk and to a theater listed in Section 81-742 (Listed theaters) or a new theater designed and intended to show live theatrical performances. Theater waiting space may be located on the same #zoning lot# occupied by a theater or a #zoning lot# immediately adjacent to a theater, and shall meet the following requirements:

1. such space shall adjoin and open onto a sidewalk or sidewalk widening for its entire length and shall have a minimum length of 30 feet measured parallel to the #street line# and a minimum clear depth of 10 feet measured perpendicular to the #street line# exclusive of any columns. Its level shall be entirely the same as that of the adjoining sidewalk. When located under an overhanging portion of a #building or other structure#, it shall have a minimum clear height of 15 feet and be free of any obstructions except for #building# columns;


2. such space shall provide direct access to a #building's# entrance or the theater's lobby. Where the theater and the theater waiting space are on separate #zoning lots#, a plaque shall be provided within the theater waiting space adjacent to the theater stating that the space is available as a waiting area for the theater audience. Such plaque shall be placed between four feet and six feet above #curb level#, and shall be visible from the sidewalk;


3. such space shall not adjoin a driveway or an off-street loading berth; and


4. the entire theater waiting space shall be illuminated with a minimum level of not less than eight horizontal foot-candles (lumens per foot).

The theater waiting space may overlap with an arcade, a #building# entrance recess area, a corner arcade, a corner circulation space or a sidewalk widening. However, the area of overlap may only be counted once toward the fulfillment of the required minimum area of pedestrian circulation space.

Where a #development# or #enlargement# is constructed on a #zoning lot# that contains at least 5,000 square feet of #lot area# and fronts on a sidewalk containing a stairway entrance or entrances into a subway station, the existing entrance or entrances shall be relocated from the #street# onto the #zoning lot#. The new entrance or entrances shall be provided in accordance with the provisions of Section 37-40 (OFF-STREET RELOCATION OR RENOVATION OF A SUBWAY STAIR). A relocated or renovated subway stair may be counted as pedestrian circulation space in accordance with the provisions of Section 37-50.

The subway stations where such improvements are required are listed in the following table and shown on Map 3 (Subway Station Improvement Areas) in Appendix A.

   2. #Block# front lots
      
      On a full #block# front lot with one or more #narrow street# frontages, a major entrance shall be located on at least one #narrow street#, except that this requirement shall not apply if the #zoning lot# contains a permitted sidewalk widening with a width of 10 feet along a #wide street#.


3. Exceptions to requirements
   
   Under the following conditions, #developments# shall not be subject to the locational requirements of this Section:
   
   
   1. where the location of an existing #building# on the #zoning lot# precludes compliance with the regulations of this Section; or
   
   
   2. where the #zoning lot# is located on a #block# where the distance between two intersections of #street lines# is less than 150 feet.

An off-street rail mass transit access improvement shall provide a new point of unobstructed off-street public access to a rail mass transit station or facility. It shall immediately adjoin, and be accessible without any obstruction from, an arcade, a #building# entrance recess area, a corner arcade, a corner circulation space, a public sidewalk, a sidewalk widening or a #public plaza#, each of which shall have a minimum horizontal dimension equal to the width of the rail mass transit access improvement. The rail mass transit access improvement may be provided within a #building# but shall not be enclosed by any doors. The area it occupies within a #building# shall not be counted toward the #floor area# of the #zoning lot#.

The Chairperson of the City Planning Commission may certify that an off-street rail mass transit access improvement satisfies the requirements of Section 81-45 (Pedestrian Circulation Space), provided that such improvement is approved by the entity which operates the mass transit station or facility and meets the following standards:

1. Dimensions
   
   An off-street mass transit access improvement shall have a minimum clear, unobstructed width of not less than 15 feet and a minimum clear, unobstructed height from finished floor to finished ceiling of not less than eight feet.


2. Obstructions

4. Enclosures
   
   The rail mass transit access improvement may be provided within a #building# but shall not be enclosed by any doors unless the Chairperson certifies that such improvement is an integral part of the #building# lobby and public circulation space, and such doors are secured only during the hours that the circulation areas of the rail mass transit facility to which it connects are closed.


5. Maintenance
   
   An off-street rail mass transit access improvement shall be maintained by the owner of the #development# or #enlargement#

One and a half times the area of the new off-street rail mass transit access improvement measured at #street# level shall, upon the Chairperson's certification, count toward the minimum area of pedestrian circulation space required under the provisions of Section 81-45, up to a maximum of 3,000 square feet.

In order to establish the Penn Center Subdistrict as a destination and enhance its retail, entertainment and commercial character and expand accessibility to its transportation network, special regulations are set forth governing the location and type of #signs#, urban design and streetscape relationships, and the improvement of pedestrian circulation to and from public transit facilities.

The regulations of Section 81-50 are applicable only in the Penn Center Subdistrict, the boundaries of which are shown on Map 1 (Special Midtown District and Subdistricts) in Appendix A of this Chapter, except as set forth for rail mass transit improvements, pursuant to Section 81-541. These regulations supplement or modify the provisions of this Chapter applying generally to the #Special Midtown District#, of which this Subdistrict is a part.

The provisions of this Section shall apply to all #zoning lots# with frontage along Seventh Avenue. The height of all #signs# shall be measured from the #curb level#.

1. #Signs#, including #advertising signs#, #flashing signs# and #illuminated signs#, unlimited in area, shall be permitted to a height of 40 feet. Below a height of 14 feet, such #signs# shall not occupy more than 50 percent of the glazed #street wall# surface required, pursuant to Section 81-42, nor shall such #signs# be located within ten feet of an entrance to a rail mass transit facility or subway station.


2. #Signs#, including #advertising signs#, #flashing signs# and #illuminated signs#, except as otherwise provided in Section 81-52, paragraph (c), may be permitted above a height of 40 feet by the City Planning Commission, upon certification that:
   
   
   1. such #signs# and #sign# structures to which #signs# are attached shall not exceed a height of 60 feet; except that #signs# and #sign# structures onto which #signs# are attached, within 40 feet of the intersection of two #streets# or within 30 feet of the centerline of the westerly prolongation of West 32nd Street along the west #block# front of Seventh Avenue between West 31st and West 33rd Streets, shall not exceed a height of 100 feet;
   
   
   2. such #signs# above a height of 60 feet are located on #zoning lots# that contain an entrance to, or are adjacent to, an entrance to a rail mass transit facility and/or subway station;
   
   
   3. such #signs# shall not project across a #street line# more than 18 inches for double- or multi-faceted #signs# or 12 inches for other signs, except that #signs# within 40 feet of the intersection of two #streets# may project up to three feet across a #street line# above a height of 25 feet;
   
   
   4. such #signs# that exceed a height of 60 feet, shall be no wider than 40 feet each;
   
   
   5. such #signs# or #sign# structures that exceed a height of 60 feet, may include lighting effects at the top of such #sign# structure and such lighting effects shall not exceed a height of 10 feet above such #sign# or #sign# structure.
   
   
   6. such #signs# and #sign# structures onto which #signs# are attached within 30 feet of the centerline of the westerly prolongation of West 32nd Street shall have a minimum clearance of 10 feet from the adjacent #building#, and such #sign# structure shall have a minimum clearance of 20 feet from the #street line# in order not to obstruct visibility of the transit entrance from the #street#;
   
   
   7. on #zoning lots# that contain an entrance to, or are adjacent to, an entrance to a rail mass transit facility and/or subway station, the requirements for rail mass transit or subway entrance informational #signs# of Section 81-521 are met; and
   
   
   8. monies will be deposited into an escrow account or similar fund established by the City, to be used at the direction of the Chairperson of the City Planning Commission and the Commissioner of the Department of Transportation, acting in consultation with the Metropolitan Transit Authority, as necessary, for streetscape and for above-grade and below-grade pedestrian circulation improvements within the Penn Center Subdistrict. For the period through January 1, 2003, and thereafter, until adjusted by rule of the City Planning Commission pursuant to the City Administrative Procedure Act, such #sign# contribution shall be equal to $30 per square foot of #sign# permitted above a height of 40 feet. Any net increase in the surface area of a previously approved #sign# shall require a new certification and the deposit of a supplemental #sign# contribution in an amount reflective of such increase.

Alternatively, an applicant may, at the time of the first certification for a #sign# at a location under its control, deposit a #sign# contribution in an amount equal to $20 per square foot of #sign# above a height of 40 feet for the total amount of square footage of all #signs# eligible for certification at locations under the applicant’s control. The deposit of monies under this alternative procedure shall not relieve the applicant of the requirement to seek and obtain a certification for each such #sign#, pursuant to this paragraph, (b), prior to installation.

For purposes of this paragraph, (b), the square footage of the #sign# shall mean the #surface area# of a #sign#, except that it shall also include the area of any structural frame or similar enclosure in which the #sign# is located or to which it is attached. No #sign# for which a certification has been received shall be installed prior to deposit of the #sign# contribution in accordance with this paragraph, (b).


3. #Signs# above a height of 40 feet on any #building# listed on the State and/or National Register of Historic Places, or any #building# formally determined eligible for inclusion on the Register, may be permitted upon authorization by the City Planning Commission, that:
   
   
   1. the proposed method of attachment of such #signs# shall be reversible;
   
   
   2. such #signs# shall not be disruptive to the historic fabric of the #building#;
   
   
   3. such #signs# shall comply with all other requirements of paragraph (b) of this Section;
   
   
   4. the requirements for rail mass transit or subway entrance informational #signs# of Section 81-521 are met; and
   
   
   5. monies shall be deposited into an escrow account or similar fund established by the City, to be used at the direction of the Chairperson of the City Planning Commission and the Commissioner of the Department of Transportation, acting in consultation with the Metropolitan Transit Authority, as necessary, for streetscape and for above-grade and below-grade pedestrian circulation improvements within the Penn Center Subdistrict. For the period through January 1, 2003, and thereafter, until adjusted by rule of the City Planning Commission pursuant to the City Administrative Procedure Act, such #sign# contribution shall be equal to $30 per square foot of #sign# permitted above a height of 40 feet. For purposes of this paragraph, (c), the square footage of the #sign# shall mean the #surface area# of a #sign#, except that it shall also include the area of any structural frame or similar enclosure in which the #sign# is located or to which it is attached. No #sign# for which an authorization has been approved shall be installed prior to deposit of the #sign# contribution in accordance with this paragraph, (c), or the alternative #sign# contribution provided in paragraph (b)(8) of this Section

Any net increase in the #surface area# of a previously approved #sign# shall require a new authorization and the deposit of a supplemental #sign# contribution in an amount reflective of such increase.

For a #zoning lot# that contains or is adjacent to an entrance or entrances to a rail mass transit facility or subway station, no permit shall be issued for any #signs# that extend or are located above a height of 40 feet, unless the City Planning Commission certifies that each such entrance is clearly identified with rail mass transit or subway entrance informational #signs# and marquees in accordance with the paragraphs (a) and (b) of this Section. Such rail mass transit or subway entrance informational #sign# or marquee shall remain, or be upgraded or replaced by a similar #sign# or marquee, for the life of the related development.

1. Rail mass transit or subway entrance informational #signs# shall prominently identify the entrance on both #streets# of a #corner lot#. Where rail mass transit or subway entrance informational #signs# are provided at the western #block# front of Seventh Avenue between West 31st and West 33rd Streets, such #signs# shall prominently identify the entrance to Pennsylvania Station to pedestrians on both Seventh Avenue and West 32nd Street. All such informational #signs# shall comply with the following requirements:
   
   
   1. such #signs# shall contain only transit information;
   
   
   2. such #signs# shall be illuminated and located no less than 12 feet above and no more than 25 feet above #curb level#;
   
   
   3. such #signs# shall contain the word “Subway” and/or appropriate other rail mass transit identification and transit line symbols. The graphic standards shall adhere to New York City Transit or other pertinent transit agency standards with all letters no less than three feet and transit symbols no less than two feet in dimension;
   
   
   4. such #signs# shall be no less than 30 feet in length on each #street# and shall extend farther than 30 feet in order to include the actual entrance; and
   
   
   5. such #signs# may project up to five feet beyond the #street line#.


2. At the rail mass transit or subway entrance, a marquee shall be provided to further identify the entrance and shall:
   
   
   1. contain only transit sign information;
   
   
   2. be illuminated and located no less than 12 feet above and no more than 25 feet above #curb level#;

   4. project no less than five feet beyond the transit or subway informational #sign#; and
   
   
   5. include illuminated mass transit identification and transit line symbols that meet the New York City Transit or other pertinent transit agency standards.

In addition to the requirements set forth in Sections 81-25 (General Provisions Relating to Height and Setback of Buildings) and 81-40 (MANDATORY DISTRICT PLAN ELEMENTS), the provisions of this Section shall apply to a #zoning lot# having 50 percent or more of its #lot area# within the Penn Center Subdistrict. For the purposes of this Section, all such #zoning lots# shall be deemed to be entirely within the Subdistrict. If any of the provisions of Sections 81-25, 81-40 and 81-53 are in conflict, the regulations of this Section shall govern.

The provisions of Section 81-42 (Retail Continuity along Designated Streets) shall apply within the Penn Center Subdistrict. However, the requirement that at least 50 percent of the #street wall# surface of each ground floor establishment be glazed with clear, untinted, transparent material, and not more that 50 percent of such transparent surface be painted or obstructed with #signs# shall not apply to any informational #signs# or marquees provided to identify rail mass transit or subway entrances in accordance with Section 81-52 (Sign Regulations).

The provisions of Section 81-43 (Street Wall Continuity Along Designated Streets) shall apply, except that the #street wall# of all #buildings# along the Seventh Avenue frontage of #zoning lots# shall be a minimum of 85 feet above #curb level# or the full height of the #building#, whichever is less. All other provisions of 81-43 shall apply without modification.

In addition, the restrictions on permitted recesses contained in Section 81-43 shall not apply to pedestrian circulation spaces provided in accordance with Sections 81-46 (Off-street Relocation or Renovation of a Subway Stair) or 81-48 (Off-street Improvement of Access to Rail Mass Transit Facility) nor to interstitial spaces between #signs# or between #building# walls and #signs#.

In addition to the provisions of Section 81-29 (Incentives by Special Permit for Provisions of Public Amenities), the City Planning Commission may grant #floor area# bonuses for subway station and/or rail mass transit facility improvements for #nonresidential# or #mixed buildings#, in accordance with Section 74-634 (Subway station improvements in Downtown Brooklyn and in Commercial Districts of 10 FAR and above in Manhattan), and may modify or waive the provisions of Section 81-43 (Street Wall Continuity Along Designated Streets) in accordance with the provisions of Section 74- 634, provided that such improvement is approved by the entities which own and/or operate the rail mass transit facility.

Prior to granting a special permit, the City Planning Commission shall be provided with:

1. a letter from each entity that operates the rail mass transit facility confirming that the drawings of the subway and/or rail mass transit improvement are of sufficient scope and detail to describe the layout and character of the improvements and that the proposed implementation of the improvements is physically and operationally feasible, and


2. a legally enforceable instrument containing:
   
   
   1. drawings of the improvements, as approved by the transit operator;
   
   
   2. provisions that all easements required for the on-site improvements will be conveyed and recorded against the property;
   
   
   3. the obligations of the applicant to construct, maintain and provide capital maintenance for the improvements; and
   
   
   4. a schedule for completion of the improvements and a requirement that a performance bond or other appropriate security be provided to ensure the completion of the improvements.

For the purposes of this Section, improvements to any rail mass transit facility on a #zoning lot# located wholly or partially within the Subdistrict qualifies for bonus #floor area# in accordance with the provisions of Section 74-634, as modified herein. For #zoning lots# located partially within the Subdistrict, such bonus #floor area# may be located anywhere on such #zoning lot#. In addition, if a subway and/or rail mass transit improvement has been constructed in accordance with an approved special permit and has received a Notice of Substantial Completion in accordance with the provisions of Section 74-634, the bonus #floor area# may be retained at the full amount granted by the special permit and may be utilized elsewhere on the #zoning lot# subject to any applicable review and approval process for such #development# or #enlargement#.

For the #zoning lot# bounded by West 34th Street, Seventh Avenue, West 33rd Street and Eighth Avenue, which contains at least 7,000 square feet of existing #publicly accessible open areas# or other bonused public amenity in the Penn Center Subdistrict, the maximum allowed #floor area# bonus for all existing #publicly accessible open areas# or other public amenities on the #zoning lot# may be retained at the amount allowed prior to October 31, 2001, subject to all other provisions of this Resolution, notwithstanding inclusion of such #zoning lot# within the #Special Midtown District#.

Special regulations are set forth in this Section to protect and strengthen the economic vitality and competitiveness of East Midtown by facilitating the development of exceptional modern and sustainable office towers; creating successful pedestrian-friendly public spaces; enabling improvements to the above- and below-grade pedestrian circulation network; protecting and strengthening the role of landmark buildings as important features of East Midtown; protecting and enhancing the role of Grand Central Terminal as a major transportation hub within East Midtown and the city; expanding and enhancing the pedestrian circulation network connecting Grand Central Terminal to surrounding development and minimizing pedestrian congestion; and protecting the iconic character of the surrounding area. Such regulations establish special provisions governing maximum floor area, sustainability, urban design and streetscape enhancements, the transfer of development rights from landmarks, and the improvement of the surface and subsurface pedestrian circulation network in the East Midtown Subdistrict.

The regulations of Section 81-60 (SPECIAL REGULATIONS FOR THE EAST MIDTOWN SUBDISTRICT), inclusive, are applicable only in the East Midtown Subdistrict, the boundaries of which are shown on Map 1 (Special Midtown District and Subdistricts) and Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter. These regulations supplement or modify the provisions of this Chapter applying generally to the #Special Midtown District#, of which this Subdistrict is a part.

Where the #lot line# of a #zoning lot# coincides with the boundary of the public place located at the southerly prolongation of Vanderbilt Avenue between East 42nd Street and East 43rd Street, such #lot line# shall be considered to be a #street line# for the purposes of applying the #use#, #bulk# and urban design regulations of this Chapter.

1. For #qualifying sites# divided by district boundaries where both districts have the same maximum #floor area ratio# set forth in Rows E and H of the table in Section 81-64 (Special Floor Area Provisions for Qualifying Sites), the provisions of Section 33-16 (Special Provisions for Zoning Lots Divided by District Boundaries) shall not apply to a #building developed# or, where permitted, #enlarged#, to exceed the basic maximum #floor area# in Row A of the table in Section 81-64. In lieu thereof, the #floor area# of such #building# on a #qualifying site# may be located anywhere on the #zoning lot#, regardless of the district boundary.
2. In addition to the requirements set forth in Sections 81-25 (General Provisions Relating to Height and Setback of Buildings) and 81-40 (MANDATORY DISTRICT PLAN ELEMENTS), the provisions of Section 81-60, inclusive, shall apply to a #zoning lot# having 50 percent or more of its #lot area# within the East Midtown Subdistrict. For the purposes of Section 81-60, inclusive, all such #zoning lots# shall be deemed to be entirely within the Subdistrict. If any of the provisions of Sections 81-25, 81-40 and 81-60, inclusive, are in conflict, the regulations of Section 81-60, inclusive, shall govern. However, for #zoning lots# located partly within the East Midtown Subdistrict and partly within the Fifth Avenue Subdistrict, the provisions of Article VII, Chapter 7 shall apply.
3. For #zoning lots# divided by subarea boundaries, the provisions of Article VII, Chapter 7 shall apply.
4. For #zoning lots# with #landmark buildings or other structures# where more than 50 percent of the #lot area# is located within the #Special Midtown District#, and which #abut# the East Midtown Subdistrict boundary, such #zoning lot# may be considered as part of the Subdistrict for the purposes of transferring development rights pursuant to the applicable provisions of Sections 81-642 (Transfer of development rights from landmarks to qualifying sites) or 81-653 (Special permit for transfer of development rights from landmarks to non-qualifying sites). However, the maximum amount of #floor area# that may be transferred from a #granting lot#, or portion thereof, located outside the Special Midtown District shall be the maximum #floor area ratio# permitted under the applicable underlying zoning district.

Non-qualifying site

For the purposes of Section 81-60, inclusive, a “non-qualifying site” shall refer to a #zoning lot# that does not meet the criteria for a #qualifying site# and is located in a subarea other than the Vanderbilt Corridor Subarea.

Public Realm Improvement Fund

For the purposes of Section 81-60, inclusive, the “Public Realm Improvement Fund” (the “Fund”) shall be a separate interest-bearing account established for the deposit of contributions made when #developments# or, where permitted, #enlargements# on #qualifying sites# in the East Midtown Subdistrict will exceed the basic maximum #floor area ratio# set forth in Section 81-64 (Special Floor Area Provisions for Qualifying Sites) through their utilization of the provisions of Sections 81-642 (Transfer of development rights from landmarks to qualifying sites) or 81-643 (Special provisions for retaining non-complying floor area in commercial buildings). The Fund shall be utilized, at the discretion of the #Public Realm Improvement Fund Governing Group#, to provide funding to implement improvements to the East Midtown Subdistrict, and its immediate vicinity, in the Borough of Manhattan. Upon receipt of any contribution, the #Public Realm Improvement Fund Governing Group# or the Department of City Planning shall notify the Comptroller of the City of New York and the Speaker of the New York City Council and promptly deposit it into the Fund.

As of August 9, 2017, the Development Rights Valuation shall be set at $307.45 per square foot.

When proposing an adjustment to the Development Rights Valuation, the Department of City Planning shall undertake a transferrable development rights valuation study conducted by qualified professionals utilizing industry best practices. The City Planning Commission shall, by rule, review and adjust the Development Rights Valuation, pursuant to the City Administrative Procedures Act not more than once every three years and not less than once every five years.

An applicant, upon written request to the Commission, may request a transferable development rights valuation study to evaluate whether the Development Rights Valuation should be modified for a particular #qualifying site# based upon any recent changes in market conditions within the Subdistrict. The study must be paid for by the applicant and completed within a one-year timeframe. The Department of City Planning shall initiate the study, to be conducted by qualified professionals utilizing industry best practices. Where the study demonstrates that the value of the development rights for the #qualifying site# is less than the Development Rights Valuation, the Commission shall, by certification, and in connection with a certification pursuant to Section 81-642 (Transfer of development rights from landmarks to qualifying sites), modify the required contribution to 20 percent of the adjusted valuation.

Public Realm Improvement Fund Governing Group

A quorum shall consist of a majority of the members.

The purpose of the Governing Group shall be to bolster and enhance East Midtown’s status as a premier central business district with a high-quality public realm, by allocating funds from the Fund to implement public realm improvement projects. The Governing Group shall establish and maintain a Public Realm Improvement Concept Plan (“Concept Plan”) for the purpose of creating a list of priority improvements, and shall have the authority to amend such Concept Plan, and associated list of improvements, as necessary. All priority improvements in the Concept Plan shall meet the criteria set forth in Section 81-683 (Criteria for improvements in the Public Realm Improvement Concept Plan).

Establishment of the Concept Plan, amendment of the Concept Plan, calendaring of items for a vote to fund, and designation of funding for a specific public realm improvement on the Concept Plan shall be decisions requiring a majority vote of the Governing Group at a meeting at which a quorum is present. If only members of the Governing Group appointed by the Mayor vote to calendar a particular public realm improvement for a vote to fund it, the Governing Group shall conduct a public hearing on the matter prior to such improvement being placed on the calendar for vote. In addition, if any member of the Governing Group puts forth a proposed public realm improvement, discussion of such improvement shall be added to the agenda of the next public meeting. Establishment of the initial Concept Plan shall be completed no later than November 1, 2017.

In the event that more than 20 million dollars remains in the Fund for more than three years, the Governing Group shall be required to hold a vote either to fund a public realm improvement project or to retain the funds.

The Governing Group shall adopt procedures for the conduct of its activities. Such procedures shall be consistent with the requirements of the New York State Open Meetings Law (Article 7, NYS Public Officers Law), which procedures shall also be consistent with the goals of the Subdistrict.

However, in the event a casualty damages or destroys a #building# within the East Midtown Subdistrict that was used as a #transient hotel# as of May 27, 2015, in the Vanderbilt Corridor Subarea or on August 9, 2017, in other Subareas, such #building# may be reconstructed and used as a #transient hotel# without obtaining a special permit, provided the #floor area# of such reconstructed #building#, less the #floor area# of any other #buildings# on the #zoning lot# does not exceed the applicable basic maximum #floor area ratio# for the #zoning lot# set forth in Section 81-60, inclusive. #Transient hotels# existing on May 27, 2015 within the Vanderbilt Corridor Subarea or on August 9, 2017, in other Subareas, shall be considered conforming #uses#.

To permit such a #transient hotel#, the Commission shall find that such #transient hotel# will:

1. be appropriate to the needs of businesses in the vicinity of the East Midtown area; and
2. provide on-site amenities and services that will support the area’s role as an office district. Such business-oriented amenities and services shall be proportionate to the scale of the #transient hotel# being proposed, and shall include, but shall not be limited to, conference and meeting facilities, and telecommunication services.

The Commission may prescribe additional conditions and safeguards to minimize adverse effects on the character of the surrounding area.

However, after August 9, 2017, #development# of a #building# containing a #transient hotel# shall be permitted under the regulations which were in effect prior to August 9, 2017, if a new building application for such #development# was filed at the Department of Buildings after June 9, 2016, and a partial permit for such application was issued by the Department of Buildings on or prior to July 20, 2017, and a temporary certificate of occupancy for the entire #building# has been granted prior to January 31, 2020. In the event that such temporary certificate of occupancy has not been granted prior to such date, and an application is filed prior to such date, pursuant to this Section, with the Board of Standards and Appeals, the Board may permit the new building permit to be renewed for a term of one year upon the following findings:

1. that the applicant has been prevented from completing such construction by hardship or circumstances beyond the applicant's control;
2. that the applicant has not recovered all or substantially all of the financial expenditures incurred in construction, nor is the applicant able to recover substantially all of the financial expenditures incurred through development that conforms and complies with any applicable amendment to this Resolution; and
3. that there are no considerations of public safety, health and welfare that have become apparent since the issuance of the permit that indicate an overriding benefit to the public in enforcement of the special permit provisions of this Section. In the event that the Board permits the renewal, the temporary certificate of occupancy shall be obtained by no later than January 31, 2021.

For #mixed buildings developed# on #qualifying sites#, the provisions of Section 32-422 (Location of floors occupied by commercial uses) are modified to permit the following #uses#, subject to the underlying zoning district regulations, on the same #story# as, or at any #story# above, #residential uses#, provided that no access exists between such #uses# at any level above the ground floor:


For such #uses#, the provisions of Section 32-41 (Enclosure Within Buildings) shall not apply.

For non-#residential buildings# or #mixed buildings# in the Vanderbilt Corridor Subarea of the East Midtown Subdistrict, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, the basic maximum #floor area ratios# of the underlying districts shall apply as set forth in this Section. Such basic maximum #floor area ratio# on any #zoning lot# may be increased by bonuses or other #floor area# allowances only in accordance with the provisions of this Chapter, and the maximum #floor area ratio# with such additional #floor area# allowances shall in no event exceed the amount set forth for each underlying district in the following table:


Any transfer of development rights from a landmark site may be made pursuant to either Section 74-79 or Section 81-632 (Special permit for transfer of development rights from landmarks to the Vanderbilt Corridor Subarea), but not both.

All applications for transfers of development rights pursuant to the special permit by the City Planning Commission in Section 81-632 (Special permit for transfer of development rights from landmarks to the Vanderbilt Corridor Subarea) shall also comply with the regulations of this Section.

3. Findings
   
   In order to grant a special permit for the transfer of development rights to a #receiving lot#, the Commission shall find that:
   
   
   1. a program for the continuing maintenance of the landmark has been established;
   2. for any proposed improvement required pursuant to this Section:
      
      
      1. the improvement to the above- or below-grade pedestrian or mass transit circulation network provided by the #development# or #enlargement# increases public accessibility to and from Grand Central Terminal;
      2. the streetscape, the site design and the location of #building# entrances contribute to the overall improvement of pedestrian circulation within the surrounding area and minimize congestion on surrounding #streets#; and
      3. a program is established to identify solutions to problems relating to vehicular and pedestrian circulation problems and the pedestrian environment within the surrounding area;
   3. where appropriate, the design of the #development# or #enlargement# includes provisions for public amenities including, but not limited to, publicly accessible open spaces, and subsurface pedestrian passageways leading to subway or rail mass transit facilities;
   4. for #developments# or #enlargements# with a proposed #floor area ratio# in excess of 21.6, the #building# has met the ground floor level, building design, sustainable design measures and, for #zoning lots# not located on two #wide streets#, the site characteristic considerations set forth in the applicable conditions and findings of Section 81-633 (Special permit for Grand Central public realm improvements);
   5. where the modification of #bulk# regulations is proposed:
      
      
      1. any proposed modification of regulations governing #zoning lots# divided by district boundaries or the permitted transfer of #floor area# will not unduly increase the #bulk# of any #development# or #enlargement# on the #receiving lot#, density of population or intensity of #use# on any #block# to the detriment of the occupants of #buildings# on the #block# or the surrounding area;
      2. for #enlargements# to existing #buildings#, any proposed modifications of height and setback requirements and the requirements of Section 81-66 are necessary because of the inherent constraints or conditions of the existing #building#, that the modifications are limited to the minimum needed, and that the proposal for modifications of height and setback requirements demonstrates to the satisfaction of the Commission that an integrated design is not feasible for the proposed #enlargement# which accommodates the transfer of development rights due to the conditions imposed by the existing #building# or configuration of the site; and
      3. for #developments# or #enlargements# on #zoning lots# of more than 40,000 square feet of #lot area# that occupy an entire #block#, any proposed modifications of #bulk# regulations are necessary because of inherent site constraints and that the modifications are limited to the minimum needed; or
   6. any proposed modifications to #street walls#, height and setback regulations and mandatory plan elements meet the applicable application requirements and findings set forth in Section 81-634 (Permitted modifications in conjunction with additional floor area).
4. Additional requirements
   
   Prior to the grant of a special permit, the applicant shall obtain approvals of plans from the MTA and any other entities that retain control and responsibility for the area of the proposed improvement, and, if appropriate, the applicant shall sign a legally enforceable instrument running with the land, setting forth the obligations of the owner and developer, their successors and assigns, to construct and maintain the improvement and shall establish a construction schedule, a program for maintenance and a schedule of hours of public operation and shall provide a performance bond for completion of the improvement.
   
   The written declaration of restrictions and any instrument creating an easement on privately owned property shall be recorded against such private property in the Office of the Register of the City of New York (County of New York) and a certified copy of the instrument shall be submitted to the Commission.
   
   No temporary certificate of occupancy for any #floor area# of the #development# or #enlargement# on a #receiving lot# shall be granted by the Department of Buildings until all required improvements have been substantially completed as determined by the Chairperson of the City Planning Commission and the area is usable by the public. Prior to the issuance of a permanent certificate of occupancy for the #development# or #enlargement#, all improvements shall be 100 percent complete in accordance with the approved plans and such completion shall have been certified by letter from the MTA.

The Commission may prescribe appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area.

For #developments# and #enlargements# on #zoning lots# located within the Vanderbilt Corridor Subarea, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, the City Planning Commission may allow, by special permit, #floor area# in excess of the basic maximum #floor area ratio# established in the table in Section 81-63 (Special Floor Area Provisions for the Vanderbilt Corridor Subarea), up to the maximum #floor area# set forth in the table, in accordance with the provisions of this Section.

All applications for a special permit for additional #floor area# pursuant to this Section shall include on-site or off-site, above- or below-grade improvements to the pedestrian or mass transit circulation network, or a combination thereof, in the Grand Central Core Area, as shown on Map 2.

2. Findings
   
   The Commission shall find that:
   1. for a #development# or #enlargement# not located on two #wide streets#, the amount of additional #floor area# being granted is appropriate based on the extent to which any or all of the following physical factors are present in the #development# or #enlargement#:
      1. direct access to subway stations and other rail mass transit facilities;
      2. the size of the #zoning lot#;
      3. the amount of wide #street# frontage; and
      4. adjacency to the open area above Grand Central Terminal;
   2. for above-grade improvements to the pedestrian circulation network that are located:
      1. on-site, the proposed improvements will, to the extent practicable, consist of a prominent space of generous proportions and quality design that is inviting to the public; improve pedestrian circulation and provide suitable amenities for the occupants; front upon a #street# or a pedestrian circulation space in close proximity to and within view of and accessible from an adjoining sidewalk; provide or be surrounded by active #uses#; be surrounded by transparent materials; provide connections to pedestrian circulation spaces in the immediate vicinity; and be designed in a manner that combines the separate elements within such space into a cohesive and harmonious site plan, resulting in a high-quality public space; or
      2. off-site, the proposed improvements to the public right-of-way, to the extent practicable, will consist of significant street and sidewalk designs that improve pedestrian circulation in the surrounding area; provide comfortable places for walking and resting, opportunities for planting and improvements to pedestrian safety; and create a better overall user experience of the above-grade pedestrian circulation network that supports the surrounding area as a high-density business district. Where the area of such improvement is to be established into a pedestrian plaza that will undergo a public design and review process through the Department of Transportation subsequent to the approval of this special permit, the Commission may waive this finding;
   3. for below-grade improvements to the pedestrian or mass transit circulation network, the proposed improvements will provide:
      1. significant and generous connections from the abovegrade pedestrian circulation network and surrounding #streets# to the below-grade pedestrian circulation network;
      2. major improvements to public accessibility in the below-grade pedestrian circulation network between and within subway stations and other rail mass transit facilities in and around Grand Central Terminal through the provision of new connections, or the addition to or reconfiguration of existing connections; or
      3. significant enhancements to the environment of subway stations and other rail mass transit facilities including daylight access, noise abatement, air quality improvement, lighting, finishes, way-finding or rider orientation, where practicable;
   4. the public benefit derived from the proposed above- or below-grade improvements to the pedestrian or mass transit circulation network merits the amount of additional #floor area# being granted to the proposed #development# or #enlargement# pursuant to this special permit;
   5. the design of the ground floor level of the #building#:
      1. contributes to a lively streetscape through a combination of retail #uses# that enliven the pedestrian experience, ample amounts of transparency and pedestrian connections that facilitate fluid movement between the #building# and adjoining public spaces; and demonstrates consideration for the location of pedestrian circulation space, #building# entrances, and the types of #uses# fronting upon the #street# or adjoining public spaces;
      2. will substantially improve the accessibility of the overall pedestrian circulation network, reduce points of pedestrian congestion and, where applicable, establish more direct and generous pedestrian connections to Grand Central Terminal; and
      3. will be well-integrated with on-site, above- or below-grade improvements required by this Section, where applicable and practicable;
   6. the design of the proposed #building#:
      1. ensures light and air to the surrounding #streets# and public spaces through the use of setbacks, recesses and other forms of articulation, and the tower top produces a distinctive addition to the Midtown Manhattan skyline which is well-integrated with the remainder of the #building#;
      2. demonstrates an integrated and well-designed facade, taking into account factors such as #street wall# articulation and fenestration, that creates a prominent and distinctive #building# which complements the character of the surrounding area, especially Grand Central Terminal; and
      3. involves a program that includes an intensity and mix of #uses# that are harmonious with the type of #uses# in the surrounding area;
   7. the proposed #development# or #enlargement# comprehensively integrates sustainable measures into the #building# and site design that:
      1. meet or exceed best practices in sustainable design; and
      2. will substantially reduce energy usage for the #building#, as compared to comparable #buildings#; and
   8. in addition:
      1. the increase in #floor area# being proposed in the #development# or #enlargement# will not unduly increase the #bulk#, density of population or intensity of #uses# to the detriment of the surrounding area; and
      2. all of the separate elements within the proposed #development# or #enlargement#, including above- or below-grade improvements, the ground floor level, #building# design, and sustainable design measures, are well–integrated and will advance the applicable goals of the #Special Midtown District# described in Section 81-00 (GENERAL PURPOSES).
3. Additional requirements
   
   Prior to the grant of a special permit pursuant to this Section, and to the extent required by the Metropolitan Transportation Authority (MTA) or any other City or State agencies with control and responsibility for the area in which a proposed improvement is to be located, the applicant shall execute an agreement, setting forth the obligations of the owner, its successors and assigns, to establish a process for design development and a preliminary construction schedule for the proposed improvement; construct the proposed improvement; where applicable, establish a program for maintenance; and, where applicable, establish a schedule of hours of public access for the proposed improvement. Where the MTA, or any other City or State agencies with control and responsibility for the area of a proposed improvement, deems necessary, such executed agreement shall set forth obligations of the applicant to provide a performance bond or other security for completion of the improvement in a form acceptable to the MTA or any other such agencies.
   
   Where the proposed #development# or #enlargement# proposes an off-site improvement located in an area to be acquired by a City or State agency, the applicant may propose a phasing plan to sequence the construction of such off-site improvement. To determine if such phasing plan is reasonable, the Commission may consult with the City or State agency that intends to acquire the area of the proposed improvement.
   
   Prior to obtaining a foundation permit or building permit from the Department of Buildings, a written declaration of restrictions, in a form acceptable to the Chairperson of the City Planning Commission, setting forth the obligations of the owner to construct, and, where applicable, maintain and provide public access to public improvements provided pursuant to this Section, shall be recorded against such property in the Office of the Register of the City of New York (County of New York). Proof of recordation of the declaration of restrictions shall be submitted in a form acceptable to the Department of City Planning.
   
   Except where a phasing plan is approved by the Commission, no temporary certificate of occupancy shall be granted by the Department of Buildings for the portion of the #building# utilizing bonus #floor area# granted pursuant to the provisions of this Section until the required improvements have been substantially completed, as determined by the Chairperson, acting in consultation with the MTA, or any other City or State agencies with control and responsibility for the area where a proposed improvement is to be located, where applicable, and such improvements are usable by the public. Such portion of the #building# utilizing bonus #floor area# shall be designated by the Commission in drawings included in the declaration of restrictions filed pursuant to this paragraph.
   
   No permanent certificate of occupancy shall be granted by the Department of Buildings for the portion of the #building# utilizing bonus #floor area# until all improvements have been completed in accordance with the approved plans, as determined by the Chairperson, acting in consultation with the MTA, or any other City or State agencies with control and responsibility for the area where a proposed improvement is to be located, where applicable.

The Commission may prescribe appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area.

In conjunction with the grant of a special permit pursuant to Section 81-633 (Special permit for Grand Central public realm improvements), the City Planning Commission may permit modifications to #street walls#, height and setback regulations and mandatory plan elements, as set forth in paragraph (a) of this Section, provided that the Commission determines that the application requirements set forth in paragraph (b) and the findings set forth in paragraph (c) of this Section are met.

1. The Commission may modify the following, whether singly or in any combination:
   1. the #street wall# regulations of Sections 81-43 (Street Wall Continuity Along Designated Streets) or 81-671 (Special street wall requirements), inclusive;
   2. the height and setback regulations of Sections 81-26 (Height and Setback Regulations - Daylight Compensation), inclusive, 81-27 (Alternate Height and Setback Regulations - Daylight Evaluation), inclusive, or 81-66 (Special Height and Setback Requirements); or

   2. to the #street wall# or height and setback regulations will result in an improved distribution of #bulk# on the #zoning lot# that is harmonious with the height and setback goals of the #Special Midtown District# set forth in Section 81-251 (Purpose of height and setback regulations).

The Commission may prescribe appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area.

For #non-residential buildings# or #mixed buildings# on #qualifying sites# in the East Midtown Subdistrict, the basic maximum #floor area ratios# of the underlying districts shall apply as set forth in this Section. Such basic maximum #floor area ratio# on any #zoning lot# may be increased by bonuses or other #floor area# allowances only in accordance with the provisions of this Chapter, and the maximum #floor area ratio# with such additional #floor area# allowances shall in no event exceed the amount set forth for each underlying district in the following table:

1. For #zoning lots# located east of Third Avenue between the centerline of East 46th Street to the centerline of East 51st Street, the maximum #floor area ratio# shall be the basic maximum #floor area ratio# set forth in Row A.

All #developments# or, where permitted, #enlargements# on #qualifying sites# located within the Grand Central Transit Improvement Zone Subarea, or the Other Transit Improvement Zone Subarea, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, that exceed the basic maximum #floor area ratio# set forth in Row A of the table in Section 81-64 (Special Floor Area Provisions for Qualifying Sites) shall comply with the provisions of this Section.

The Chairperson of the City Planning Commission shall allow, by certification, #floor area# on a #qualifying site# to be increased above the applicable basic maximum #floor area ratio# provided that such resulting increase in #floor area ratio# is not less than the minimum specified in Row B of the table in Section 81-64, nor more than the maximum specified in Row C, as applicable, and further provided that a transit improvement, or a combination of transit improvements, will be constructed in the Grand Central Transit Improvement Zone Subarea, or the Other Transit Improvement Zone Subarea, in accordance with the provisions of this Section.

1. The following requirements shall be completed prior to application for certification by the Chairperson:
   1. the applicant shall select a transit improvement that has been identified on the Priority Improvement List in Section 81-682 (Priority Improvement List for qualifying sites) and is commensurate with the minimum #floor area# required, and results in a #floor area ratio# increase not exceeding the maximum #floor area ratio# permitted to be achieved through the provisions of this Section. The process for such selection shall also comply with paragraph (a) of Section 81-682;
   2. the applicant shall submit preliminary plans for the proposed transit improvement to the Chairperson and any applicable City or State agencies with jurisdiction over and control of the proposed transit improvement;
   3. the applicant shall obtain and provide to the Chairperson a conceptual approval of the proposed transit improvement from any applicable City or State agencies with jurisdiction over and control of the proposed improvement in letter form, wherein such agencies state that such improvements meet the requirements set forth in Section 81-682; and

2. The following items shall be submitted to the Chairperson as part of an application for certification:
   1. all of the materials required pursuant to paragraph (a) of this Section;
   2. site plans and zoning calculations for the proposed #development# or, where permitted, #enlargement# on the #qualifying site# showing the additional #floor area# associated with the completion of such transit improvement; and
   3. drawings including, but not limited to, plans, sections, elevations, three-dimensional projections or other drawings deemed necessary or relevant by the Chairperson for the transit improvement, and any such other information as may be required by the Chairperson.

When an applicant has submitted materials to the Chairperson that satisfy the requirements of paragraphs (a) and (b) of this Section, the Chairperson shall certify to the Department of Buildings that the #development# or, where permitted, #enlargement# on a #qualifying site# is in compliance with the provisions of this Section. Such certification shall be a precondition to the issuance of any foundation permit or new building permit by the Department of Buildings allowing a #development# or, where permitted, an #enlargement# on a #qualifying site# in the Grand Central Transit Improvement Zone Subarea, or the Other Transit Improvement Zone Subarea. All applications pursuant to this Section shall be referred to the affected Community Board, the local Council Member and the Manhattan Borough President. No certification shall be granted prior to 60 days after such referral.

No temporary certificate of occupancy shall be granted by the Department of Buildings for the portion of the #building# identified as utilizing the additional #floor area# granted pursuant to the provisions of this Section until the Chairperson, acting in consultation with the applicable City or State agencies having jurisdiction over and control of the proposed improvement, has certified that the improvements are substantially complete and usable by the public. Such portion of the #building# shall be designated by the applicant in drawings included in the instruments filed pursuant to paragraph (b) of this Section and shall be noted on the temporary certificate of occupancy.

No permanent certificate of occupancy shall be granted by the Department of Buildings for the portion of the #building# utilizing such additional #floor area# until the improvements have been finally completed in accordance with the approved plans and such final completion has been certified by the Chairperson, acting in consultation with the applicable City or State agencies having jurisdiction over and control of the proposed improvement.

In addition, the Chairperson shall allow, by certification, a reduction in, or waiver of, the minimum #floor area ratio# required pursuant to Row B of the table in Section 81-64, where there are an insufficient number of available projects on the Priority Improvement List in Section 81-682. The Chairperson shall also allow, by certification, the maximum #floor area ratio# for a #qualifying site# to be increased beyond the limit set forth in Row C of the table in Section 81-64, where the Metropolitan Transportation Authority requires improvements to the Fifth Avenue and East 53rd Street Station to be combined in order to adequately phase improvements and avoid practical difficulties in operating the station.

The Chairperson of the City Planning Commission shall allow, by certification, a transfer of development rights from #zoning lots# occupied by #landmark buildings or other structures# within the East Midtown Subdistrict to a #qualifying site#, provided that the provisions of this Section are met.

1. The transfer of development rights shall be subject to the following conditions:
   1. For #qualifying sites# in the Grand Central Transit Improvement Zone Subarea, or the Other Transit Improvement Zone Subarea, as shown on Map 2 (East Midtown Subdistrict and Subareas), the applicant shall obtain a certification pursuant to Section 81-641 (Additional floor area for transit improvements on qualifying sites) prior to, or in conjunction with, meeting the requirements of this Section.
   2. The maximum amount of #floor area# that may be transferred from a #granting lot# shall be the applicable basic maximum #floor area# set forth in Section 81-64 (Special Floor Area Provisions for Qualifying Sites), less the total #floor area# of all existing #buildings# on the landmark #zoning lot#, and any previously transferred #floor area#. In no event shall a #granting lot# transfer any previously granted bonus #floor area# received for subway station improvements, #publicly accessible open areas# or the provision of district improvements pursuant to the provisions of this Chapter, or any preceding regulations.
   3. For each #receiving lot#, the increased #floor area# allowed by the transfer of development rights pursuant to this Section shall not exceed the amount resulting in the maximum #floor area ratio# set forth in Row D of the table in Section 81-64.
   4. Each transfer, once completed, shall irrevocably reduce the amount of #floor area# that may be #developed# or #enlarged# on the #granting lot# by the amount of #floor area# transferred. If the landmark designation is removed from the #landmark building or other structure#, the #landmark building or other structure# is destroyed or #enlarged#, or the #zoning lot# with the #landmark building or structure# is redeveloped, the #granting lot# may only be #developed# or #enlarged# up to the amount of permitted #floor area# as reduced by each transfer.
   5. Prior to the issuance of a building permit, as set forth in paragraph (c) of this Section, the owners of the #granting lot# and the #receiving lot# shall submit to the Chairperson a copy of the transfer instrument legally sufficient in both form and content to effect such a transfer. Notice of the restrictions upon further #development# or #enlargement# of the #granting lot# and the #receiving lot# shall be filed by the owners of the respective lots in the Office of the Register of the City of New York (County of New York). Proof of recordation shall be submitted to the Chairperson.
      
      Both the transfer instrument and the notices of restrictions shall specify the total amount of #floor area# transferred and shall specify, by lot and block numbers, the #granting lot# and the #receiving lot# that are a party to such transfer.
   6. Prior to the issuance of a building permit, as set forth in this Section, a non-refundable contribution shall have been deposited by the applicant into the #Public Realm Improvement Fund#. Such contribution shall be equal to the greater of:
      1. 20 percent of the #sales price# of the transferred #floor area#; or
      2. an amount equal to 20 percent of the #Public Realm Improvement Fund Development Rights Valuation# multiplied by the amount of transferred #floor area#.
2. An application filed with the Chairperson for certification pursuant to this Section shall be made jointly by the owners of the #granting lot# and the #receiving lot#. The following items shall be submitted to the Chairperson as part of an application for certification:
   1. for #qualifying sites# in the Grand Central Transit Improvement Zone Subarea, or the Other Transit Improvement Zone Subarea, materials that are sufficient to demonstrate compliance with the provisions of Section 81-641;
   2. site plans and zoning calculations for the #granting lot# and #receiving lot# showing the additional #floor area# associated with the transfer, and any such other information as may be required by the Chairperson;
   3. materials to demonstrate the establishment of a program for the continuing maintenance of the #landmark building or other structure#;
   4. a report from the Landmarks Preservation Commission concerning the continuing maintenance program of the #landmark building or other structure#; and
   5. for those #receiving lots# that are contiguous to a lot occupied by Grand Central Terminal or a lot that is across a #street# and opposite the lot occupied by Grand Central Terminal, or, in the case of a #corner lot#, one that fronts on the same #street# intersection as the lot occupied by Grand Central Terminal, a report from the Landmarks Preservation Commission concerning the harmonious relationship of the #development# or, where permitted, #enlargement# to Grand Central Terminal.
   All applications pursuant to this Section shall be referred to the affected Community Board, the local Council Member and the Borough President of Manhattan. No certification shall be granted prior to 60 days after such referral.
   
   The Chairperson shall certify to the Department of Buildings that a #development# or, where permitted, an #enlargement# on a #qualifying site# is in compliance with the provisions of this Section only after the following have been received:
   1. the instrument of transfer and notice of restrictions required by paragraph (a) of this Section have been executed and recorded with proof of recordation provided to the Chairperson;
   2. documents confirming the #sale price# have been provided to the Chairperson, including, but not limited to, the real property transfer tax return form recorded with the New York City Department of Finance and the details of consideration schedule; and
   3. payment of a non-refundable contribution to the #Public Realm Improvement Fund# in the amount required by paragraph (a) of this Section has been made.

Such certification shall be a precondition to the filing for or issuing of any building permit allowing more than the basic maximum #floor area ratio# for such #development# or, where permitted, #enlargement# on a #qualifying site#. Additional provisions are set forth in Section 81-686 for applicants undertaking a sidewalk improvement immediately adjacent to their #qualifying site#.

A separate application shall be filed for each transfer of development rights to an independent #receiving lot# pursuant to this Section.

For #non-complying commercial buildings# existing on December 15, 1961 with #non-complying floor area#, the provisions of Section 54-41 (Permitted Reconstruction) may be modified to allow such #non-complying building# to be demolished or altered, to the extent of 75 percent or more of its total #floor area#, and reconstructed on a #qualifying site# to retain the amount of pre-existing #non-complying floor area# in accordance with the applicable district #bulk# regulations of this Chapter, upon certification by the Chairperson of the City Planning Commission to the Department of Buildings first, that prior to demolition or alteration, the applicant meets the provisions of paragraph (a) of this Section, as applicable, and, subsequently, prior to reconstruction, the proposed #development# will comply with the applicable provisions of paragraph (b) of this Section. For purposes of this Chapter, the reconstruction of such #non-complying floor area# shall be considered a #development#. Any #enlargement# of a #non-complying commercial building# on a #qualifying site# shall be permitted only pursuant to paragraph (a) of Section 81-684 (Authorizations for qualifying sites), or Section 81-685 (Special permit to modify qualifying site provisions).

1. Certification to demolish or alter a #non-complying building#
   
   The Chairperson shall certify the amount of #non-complying floor area# existing within a #non-complying building# that may be reconstructed pursuant to the provisions of paragraph (b) of this Section, based on calculations submitted to the Chairperson. Such calculations shall be based on either the #building’s# construction documents previously approved by the Department of Buildings at the time of such #building’s# construction, #enlargement#, or subsequent alterations, as applicable; or on an as-built drawing set completed by a registered architect.
   
   For the purpose of calculating the amount of #non-complying floor area# to be retained on #zoning lots# with multiple existing #buildings# at the time of application, the maximum amount of #non-complying floor area# that may be reconstructed shall be equivalent to the #floor area# of the #zoning lot# at the time of application, less the total #floor area# of all existing #buildings# to remain.
   
   Certification pursuant to the provisions of paragraph (a) of this Section shall be a precondition to the issuance of any demolition or alteration permit by the Department of Buildings for a #zoning lot# reconstructing #non-complying floor area#.
2. Certification to reconstruct #non-complying floor area# The amount of #non-complying floor area# established pursuant to paragraph (a) of this Section may be reconstructed, provided that the Chairperson certifies that:
   1. all requirements for #qualifying sites# set forth in the definition in Section 81-613, inclusive, have been met, except that no publicly accessible space shall be required notwithstanding the provisions of paragraph (f) of the definition of #qualifying site#; and
   2. a non-refundable contribution has been deposited by the applicant into the #Public Realm Improvement Fund#. Such contribution shall be an amount equal to 20 percent of the #Public Realm Improvement Fund Development Rights Valuation# multiplied by the amount of such pre-existing #non-complying floor area#.
The payment of the non-refundable contribution to the #Public Realm Improvement Fund# pursuant to the provisions of paragraph (b) of this Section, shall be a precondition to the issuance of any foundation permit or new building or alteration permit by the Department of Buildings allowing a #development# on a #qualifying site#.

All applications pursuant to this Section shall be referred to the affected Community Board, the local Council Member and the Borough President of Manhattan. No certification shall be granted prior to 60 days after such referral.

Except for #zoning lots# located east of Third Avenue between the centerline of East 46th Street to the centerline of East 51st Street, any proposed #floor area# in the #development# beyond the amount contained in the pre-existing #non-complying building# may be obtained by utilizing the applicable provisions of Section 81-64 (Special Floor Area Provisions for Qualifying Sites). For the purposes of applying the provisions of such Section, the reconstructed #floor area ratio# shall be considered the basic maximum #floor area ratio#. However, the maximum #floor area ratios# of Row E and Row H of the table in Section 81-64 shall continue to apply.

For #qualifying sites# located in the Grand Central Transit Improvement Zone Subarea, or the Other Transit Improvement Zone Subarea, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, the City Planning Commission may permit an increase in the amount of #floor area ratio# permitted on such #zoning lots#, up to the amount specified in Row F of the table in Section 81-64 (Special Floor Area Provisions for Qualifying Sites), as applicable, where subway station improvements are made in accordance with the provisions of Sections 81-292 (Subway station improvements) and 74-634 (Subway station improvements in Downtown Brooklyn and in Commercial Districts of 10 FAR and above in Manhattan).

As a pre-condition to applying for such special permit, an applicant shall demonstrate that the maximum as-of-right #floor area ratio# for #qualifying sites# set forth in Row E of the table in Section 81-64 has been achieved prior to, or in conjunction with, the special permit application.

For #qualifying sites#, the City Planning Commission may permit an increase in the amount of #floor area ratio# permitted on such #zoning lots#, up to the amount specified in Row G of the table in Section 81-64 (Special Floor Area Provisions for Qualifying Sites), as applicable, where an above-grade public concourse, in the form of an open or enclosed, publicly accessible space for public use and enjoyment, is provided on the #qualifying site#. Such publicly accessible spaces shall include amenities that are characteristic of #public plazas# or public atriums, as applicable, for the comfort and convenience of the public.

As a pre-condition to applying for such special permit, an applicant shall demonstrate that the maximum as-of-right #floor area ratio# for #qualifying sites# set forth in Row E of the table in Section 81-64 has been achieved prior to, or in conjunction with, the special permit application.

In order for the City Planning Commission to approve a special permit application for additional #floor area#, the Commission shall determine that such #development# or, where permitted, #enlargement#, complies with the conditions and application requirements of paragraph (a), the findings of paragraph (b) and the additional requirements of paragraph (c) of this Section.

1. Applications shall include information and justification sufficient to provide the Commission with the basis for:
   1. evaluating the benefits to the general public;
   2. determining the appropriate amount of increased #floor area# to grant; and
   3. determining whether the applicable findings set forth in paragraph (b) of this Section have been met. Such application materials shall also include initial plans for the maintenance of the proposed improvements.
2. The Commission shall find that:
   1. to the extent practicable, the open or enclosed public concourse will:
      1. consist of a prominent space of generous proportions and quality design that is inviting to the public;
      2. improve pedestrian circulation and provide suitable amenities for the occupants;
      3. front upon a #street# or a pedestrian circulation space in close proximity to and within view of, and accessible from, an adjoining sidewalk;
      4. provide or be surrounded by active #uses#;
      5. be surrounded by transparent materials;
      6. provide connections to pedestrian circulation spaces in the immediate vicinity; and
      7. be designed in a manner that combines the separate elements within such space into a cohesive and harmonious site plan, resulting in a high-quality public space; and
   2. the public benefit derived from the proposed public concourse merits the amount of additional #floor area# being granted to the proposed #development# or, where permitted, #enlargement#, pursuant to this special permit;
3. Prior to obtaining a foundation permit or building permit for a #development or, where permitted, an #enlargement# on a #qualifying site#, from the Department of Buildings, a written declaration of restrictions, in a form acceptable to the Chairperson of the City Planning Commission, setting forth the obligations of the owner to construct, maintain and provide public access to public improvements provided pursuant to this Section, shall be recorded against such property in the Office of the Register of the City of New York (County of New York). Proof of recordation of the declaration of restrictions shall be submitted in a form acceptable to the Department of City Planning.
   
   No temporary certificate of occupancy shall be granted by the Department of Buildings for the portion of the #building# utilizing increased #floor area# granted pursuant to the provisions of this Section until the required improvements have been substantially completed, as determined by the Chairperson, and such improvements are usable by the public. Such portion of the #building# utilizing increased #floor area# shall be designated by the Commission in drawings included in the declaration of restrictions filed pursuant to this paragraph.
   
   No permanent certificate of occupancy shall be granted by the Department of Buildings for the portion of the #building# utilizing increased #floor area# until all improvements have been finally completed in accordance with the approved plans, as determined by the Chairperson.

For #non-residential buildings# or #mixed buildings# on #non-qualifying sites# in the East Midtown Subdistrict, the basic maximum #floor area ratios# of the underlying districts shall apply as set forth in this Section. Such basic maximum #floor area ratio# on any #zoning lot# may be increased by bonuses or other #floor area# allowances only in accordance with the provisions of this Chapter, and the maximum #floor area ratio# with such additional #floor area# allowances shall in no event exceed the amount set forth for each underlying district in the following table:

For #non-qualifying sites# in subareas outside the Grand Central Core Area, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, the basic maximum #floor area ratio# permitted on such #zoning lots# shall be increased, up to the amount specified in Row B of the table in Section 81-65 (Special Floor Area Provisions for All Non-qualifying Sites), where a #public plaza# is provided in accordance with the provisions of Section 81-23 (Floor Area Bonus for Public Plazas).

For #non-qualifying sites#, the City Planning Commission may permit an increase in the amount of #floor area ratio# permitted on such #zoning lots#, up to the amount specified in Row D of the table in Section 81-65 (Special Floor Area Provisions for All Non-qualifying Sites), as applicable, where subway station improvements are made in accordance with the provisions of Sections 81-292 (Subway station improvements) and Section 74-634 (Subway station improvements in Downtown Brooklyn and in Commercial Districts of 10 FAR and above in Manhattan).

For #non-qualifying sites#, the City Planning Commission may permit the transfer of development rights from a #granting lot# to a #receiving lot#, pursuant to the provisions of Section 74-79 (Transfer of Development Rights From Landmark Sites), provided that:

1. the maximum amount of #floor area# that may be transferred from a #granting lot# shall be the applicable basic maximum #floor area# set forth in Section 81-65 (Special Floor Area Provisions for All Non-qualifying Sites), less the total #floor area# of all existing #buildings# on the landmark #zoning lot#, and any previously transferred #floor area#. In no event shall a #granting lot# transfer any previously granted bonus #floor area# received for subway station improvements, #publicly accessible open areas# or the provision of district improvements pursuant to the provisions of this Chapter, or any preceding regulations;
2. for each #receiving lot#, the increased #floor area# allowed by the transfer of development rights pursuant to this Section shall not exceed the amount resulting in the maximum #floor area ratio# set forth in Row F of the table in Section 81-65; and
3. each transfer, once completed, shall irrevocably reduce the amount of #floor area# that may be #developed# or #enlarged# on the #granting lot# by the amount of #floor area# transferred.

For #buildings# which are #developed# or #enlarged# within the East Midtown Subdistrict, the applicable height and setback regulations of Sections 81-26 (Height and Setback Regulations – Daylight Compensation), inclusive, and 81-27 (Alternate Height and Setback Regulations – Daylight Evaluation), inclusive, are modified by the provisions of this Section, inclusive.

For #buildings# on #non-qualifying sites# within the Grand Central Core Area, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, the provisions of Sections 81-26 (Height and Setback Regulations – Daylight Compensation), inclusive, or 81-27 (Alternate Height and Setback Regulations – Daylight Evaluation), inclusive, are modified as follows:

1. where such #buildings# are governed by Section 81-26, no #compensating recess# shall be required for the #encroachment# of that portion of the #building# below a height of 150 feet, as measured from #curb level#; or
2. where such #buildings# are governed by Section 81-27, the computation of daylight evaluation shall not include any daylight blockage, daylight credit, profile daylight blockage or available daylight for that portion of the #building# below 150 feet above #curb level#. However, the passing score required pursuant to paragraph (i) of Section 81-274 shall apply.

For #buildings# on #qualifying sites# in the East Midtown Subdistrict using the daylight compensation method of height and setback regulations, the provisions of Section 81-26 (Height and Setback Regulations – Daylight Compensation) are modified as follows:

1. for the purposes of determining permitted #encroachments# and #compensating recesses# pursuant to Section 81-264 (Encroachments and compensating recesses):
   1. no #compensating recess# shall be required for the #encroachment# of that portion of the #building# below a height of 150 feet, as measured from #curb level#;
   2. #compensating recesses# provided for #encroachments#, or portions thereof, above a height of 400 feet, as measured from #curb level#, need not comply with the provisions of paragraph (c)(1) of Section 81-264. In lieu thereof, for any portion of the #building# located above a height of 400 feet, the amount of #compensating recess# required for any particular level of the #building# shall be equal to the amount of #encroachment# provided at such level. The remaining provisions of paragraph (c) of Section 81-264 shall continue to apply to such #compensating recess#; and
   3. for #buildings# on #qualifying sites# with frontage along the easterly side of Vanderbilt Avenue, the full width of Vanderbilt Avenue may be considered part of the #zoning lot# for the purposes of determining permitted #encroachments# and #compensating recesses#. Such modified #zoning lot# shall be constructed by shifting the westerly boundary of the #zoning lot# to the westerly #street line# of Vanderbilt Avenue, and by prolonging the #narrow street lines# to such new westerly boundary. The Vanderbilt Avenue portion of such modified #zoning lot# may be considered a #compensating recess# for encroachments along such #building’s narrow street frontage zone#, provided that any portion of the #building# fronting along Vanderbilt Avenue above a height of 100 feet, as measured from #curb level#, is set back a minimum 15 feet from the Vanderbilt Avenue #street line#, and further provided that the #street frontage zone# calculation along Park Avenue shall not include Vanderbilt Avenue;
2. for the purposes of determining the permitted length of #encroachments# pursuant to Section 81-265 (Encroachment limitations by length and height rules) the minimum length of recess required by Formula 2 in paragraph (c) of Section 81-265 shall be modified to 20 percent of the length of the #front lot line#; and
3. for #buildings# on #qualifying sites# with frontage along Park Avenue, as an alternative to the setback requirements of Table A, B or C in paragraph (b) of Section 81-263 (Standard setback requirements), the Park Avenue wall of such #building# shall be set back behind the applicable #setback line# to the depth of the #setback line# required at that particular height, in accordance with the applicable requirements of the table in this Section.

For #buildings# on #qualifying sites# in the East Midtown Subdistrict using the daylight evaluation method of height and setback regulations, the provisions of Section 81-27 (Alternate Height and Setback Regulations – Daylight Evaluation) are modified as follows:

1. for the purposes of calculating the daylight evaluation score pursuant to Section 81-274 (Rules for determining the daylight evaluation score):
   1. the computation of daylight evaluation shall not include any daylight blockage for that portion of the #building# above the curved line representing 70 degrees in the applicable Daylight Evaluation Charts, and below a height of 150 feet, as measured from #curb level#. However, such computation shall include the daylight blockage created by extending the lines representing the outermost edges of the portion of the #building# above a height of 150 feet downwards to such 70 degree line;
   2. the computation of unblocked daylight squares which are below the curved line representing an elevation of 70 degrees, pursuant to paragraph (c) of Section 81-274, may apply along designated #streets# where #street wall# continuity is required;
   3. the profile penalty for #profile encroachment#, set forth in paragraph (a) of Section 81-274, shall not apply; and
   4. the provisions of paragraph (i) of Section 81-274 shall be modified to require an overall passing score of 66 percent. Notwithstanding such modifications, no single #street# frontage shall have a street score of less than 66 percent;
2. the reflectivity provisions of Section 81-276 may be utilized to raise both an individual score and the overall score by up to six percentage points;
3. for #buildings# on #qualifying sites# with frontage along the easterly #street line# of Vanderbilt Avenue, the full width of Vanderbilt Avenue may be considered part of the #zoning lot# for the purposes of constructing the #daylight evaluation chart# pursuant to Section 81-272 (Features of the Daylight Evaluation Chart). Such modified #zoning lot# shall be constructed by shifting the westerly boundary of the #zoning lot# to the westerly #street line# of Vanderbilt Avenue, and by prolonging the #narrow street lines# to such new westerly boundary. Such modified #zoning lot# may be utilized to create a modified pedestrian view along Vanderbilt Avenue and intersecting #narrow streets# provided that:
   1. any portion of the #building# fronting along Vanderbilt Avenue above a height of 100 feet, as measured from #curb level#, is set back a minimum of 15 feet from the Vanderbilt Avenue #street line#;
   2. #vantage points# along Vanderbilt Avenue are taken 30 feet west of the westerly #street line# instead of the #center line of the street#; and
   3. #vantage points# along #narrow streets# are taken from the corner of the modified #zoning lot#; and
4. for #buildings# with frontage along Park Avenue:
   1. for the purposes of establishing #vantage points# along Park Avenue to construct a #daylight evaluation chart# pursuant to the provisions of Section 81-272, the definition of #centerline of the street#, as set forth in Section 81-271 (Definitions), shall be modified along Park Avenue to be a line 70 feet from, and parallel to, the Park Avenue #street line# of the #zoning lot#; and
   2. for the purpose of plotting #buildings# on the #daylight evaluation chart# pursuant to Section 81-273 (Rules for plotting buildings on the daylight evaluation chart), Chart 4 (Daylight Evaluation Diagram – Park Avenue) in Appendix B of this Chapter shall be utilized in lieu of the chart for #streets# 100 feet or more in width.

For #buildings# which are #developed# or #enlarged# within the East Midtown Subdistrict, the applicable provisions of Section 81-40 (MANDATORY DISTRICT PLAN ELEMENTS) shall be modified in accordance with the provisions of this Section, inclusive.

The requirements of Section 81-43 (Street Wall Continuity Along Designated Streets) shall be applicable within the Subdistrict, except as modified in this Section.

On 42nd Street, the #street wall# shall be at the #street line#. The width of the required #street wall# shall be at least 80 percent of the length of the #front lot line#. The minimum height of such #street walls# without any setback shall be 120 feet above #curb level# or the height of the #building#, whichever is less, and the maximum height shall not exceed 150 feet above #curb level#. Where a #zoning lot# is bounded by the intersection of Park Avenue, Lexington Avenue, Madison Avenue, Vanderbilt Avenue, 42nd Street or Depew Place and any other #street#, these #street wall# height regulations shall apply along the full length of the #zoning lot# along the other #street# or to a distance of 125 feet from the intersection, whichever is less.

However, for #developments# or, where permitted, #enlargements# on #qualifying sites# within an area bounded by East 43rd Street, Second Avenue, East 42nd Street and a line 200 feet east of Third Avenue, such #street wall# location requirements shall not apply to the portion of the frontage where an open publicly accessible space is provided in accordance with paragraph (b) of Section 81-681 (Mandatory requirements for qualifying sites).

Beyond 125 feet of the intersection, the maximum height of the #street wall# above #curb level# shall not exceed 120 feet. For such #buildings#, the provisions of Section 81-262 (Maximum height of front wall at the street line) shall not be applicable.

However, the ten-foot setback requirement of paragraph (a) of Section 81-263 (Standard setback requirements) shall apply only to those portions of the #building# above 120 feet.

All sidewalk widenings provided pursuant to the provisions of this Section shall be improved as sidewalks to Department of Transportation standards, shall be at the same level as the adjoining public sidewalks, and shall be accessible to the public at all times. The design provisions set forth in paragraph (f) of Section 37-53 (Design Standards for Pedestrian Circulation Spaces) shall apply, except as modified in this Section. All sidewalk widenings provided in accordance with the provisions of this Section shall constitute pedestrian circulation space, as required pursuant to Section 81-45 (Pedestrian Circulation Space).

1. Mandatory sidewalk widenings along Madison and Lexington Avenues
   
   #Developments# or, where permitted, #enlargements# on #qualifying sites# with frontage along Madison and Lexington Avenues, shall provide mandatory sidewalk widenings as follows:
   1. where such #zoning lot# occupies the entire #block# frontage, a sidewalk widening shall be provided to the extent necessary so that a minimum sidewalk width of 20 feet is achieved, including portions within and beyond the #zoning lot#. However, no sidewalk widening need exceed 10 feet, as measured perpendicular to the #street line#;
   2. where such #zoning lot# does not occupy the entire #block# frontage, a sidewalk widening shall be provided where all existing #buildings# on the #block# frontage have provided such a widening. Such required widening shall match the amount of widened sidewalk provided on adjacent #zoning lots#, provided that no sidewalk widening need exceed 10 feet, as measured perpendicular to the #street line#.
2. Permitted sidewalk widenings
   
   Sidewalk widenings may be provided, in accordance with the applicable size and design standards established in Section 37-50 (REQUIREMENTS FOR PEDESTRIAN CIRCULATION SPACE), inclusive:
   1. along #narrow streets# in the Grand Central Subarea, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, for #developments# or #enlargements# on #zoning lots# with a #lot width# of 100 feet or more, as measured along such #narrow street line#; and

1. On #qualifying sites#
   
   Where a #zoning lot# contains an easement volume for pedestrian access to a subway station or rail mass transit facility and such #zoning lot# is proposed to be #developed# or, where permitted, #enlarged# in accordance with the provisions for #qualifying sites#, such existing easement volume shall be preserved, or reconfigured in accordance with standards and terms approved by the Metropolitan Transportation Authority (MTA), as part of such #development# or #enlargement#. Any reconfiguration shall be constructed by the owner of the #development# or #enlargement#.
   
   For such #developments# or, where permitted, #enlargements#, the owner shall submit a site plan showing a proposed location and size of the transit easement volume that would provide access between the #street# and the below-grade subway station or rail mass transit facility and be compatible with the proposed #development# or #enlargement# on the #zoning lot# for joint approval and final certification by the MTA and the Chairperson of the City Planning Commission. The MTA and the Chairperson shall comment on such site plan within 45 days of its receipt and may, within such 45-day period or following its expiration, permit the granting of an excavation permit while the location and size of the transit easement volume is being finalized. Upon joint approval of a site plan by the MTA and the Chairperson, copies of such certification shall be forwarded by the Chairperson to the Department of Buildings.
   
   Legal instruments creating a transit easement volume shall be executed and recorded in a form acceptable to the City. The execution and recording of such instruments shall be a precondition to the issuance of any foundation permit, new building permit, or alteration permit by the Department of Buildings allowing such #development# or #enlargement#.
2. On #qualifying sites# in the Grand Central Transit Improvement Zone Subarea or in the Other Transit Improvement Zone Subarea
   
   For #developments# or, where permitted, #enlargements# involving ground floor level construction on #qualifying sites# in the Grand Central Transit Improvement Zone Subarea, or in the Other Transit Improvement Zone Subarea, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, in addition to the provisions of paragraph (a) of this Section, as applicable, a transit easement volume may be required on such #zoning lot# for public access between the #street# and a below-grade subway station or rail mass transit facility.
   
   Prior to filing any applications with the Department of Buildings for an excavation permit, foundation permit, new building permit or alteration permit for a #development# or #enlargement#, the owner of the #zoning lot# shall file an application with the MTA and the Chairperson requesting a certification as to whether or not a transit easement volume is required on the #zoning lot#.
   
   Within 60 days of receipt of such application, the MTA and the Chairperson shall jointly certify whether or not a transit easement volume is required on the #zoning lot#. Failure to certify within the 60-day period will release the owner from any obligation to provide a transit easement volume on such #zoning lot#.
   
   When the MTA and the Chairperson indicate that a transit easement volume is required, the owner shall submit a site plan showing a proposed location and size of the transit easement volume that would provide access between the #street# and the below-grade subway station or rail mass transit facility and be compatible with the proposed #development# or #enlargement# on the #zoning lot# for joint approval and final certification by the MTA and the Chairperson. The MTA and the Chairperson shall comment on such site plan within 45 days of its receipt and may, within such 45-day period or following its expiration, permit the granting of an excavation permit while the location and size of the transit easement volume is being finalized. Upon joint approval of a site plan by the MTA and the Chairperson, copies of such certification shall be forwarded by the Chairperson to the Department of Buildings.
   
   Legal instruments creating a transit easement volume shall be executed and recorded in a form acceptable to the City. The execution and recording of such instruments shall be a precondition to the issuance of any foundation permit, new building permit, or alteration permit by the Department of Buildings allowing such #development# or #enlargement#.

   1. where such mass transit access improvement is constructed and maintained by the owner of the #development# or #enlargement#:
      1. such mass transit access shall be improved to the standards set forth in Section 81-48 and shall be approved by the MTA, and shall comply with the following:
         1. where the lobby of the #building# adjoins such mass transit access, in addition to mass transit access to the #street#, such mass transit access shall provide a direct connection to the lobby of the #building# that is open during normal business hours; and
         2. such mass transit access shall provide directional #signs# in accordance with the provisions of Section 81-412 (Directional signs). Such #signs# shall be exempt from the maximum #surface area# of non-#illuminated signs# permitted by Section 32-642 (Non-illuminated signs); and
      2. no temporary certificate of occupancy shall be granted by the Department of Buildings for the #building# until the Chairperson of the City Planning Commission, acting in consultation with the MTA, has certified that the improvements are substantially complete and usable by the public.
   2. where such mass transit access improvement is constructed and maintained by the MTA:
      1. where construction of the transit easement volume by the MTA is not contemporaneous with the construction of the #development#:
         1. any underground walls constructed along the #front lot line# of a #zoning lot# shall contain a knockout panel, not less than 12 feet wide, below #curb level# down to the bottom of the easement. The actual location and size of such knockout panel shall be determined through consultation with the MTA; and
         2. temporary construction access shall be granted to the MTA on portions of the #zoning lot# outside of the transit easement volume, as necessary, to enable construction within and connection to the transit easement volume; and
      2. in the event that the MTA has approved of obstructions associated with the #development# or #enlargement# within the transit easement volume, such as building columns or footings, such construction and maintenance shall exclude any such obstructions within the transit easement volume.
3. In other locations
   
   For portions of the #Special Midtown District# within the #Special Transit Land Use District#, where, as part of a #development# or #enlargement# involving ground floor level construction, a transit easement volume is required by the MTA to accommodate, whether singly or in any combination, light wells, stairs, ramps, escalators, elevators, passageways, or ancillary facilities required to support the functioning of subway station or rail mass transit facilities, including, but not limited to, emergency egress or ventilation structures, the MTA shall, in consultation with the owner of the #zoning lot# and the City Planning Commission, determine the appropriate type of transit easement and reasonable dimensions for such transit easement volume.

The floor space occupied by any transit easement volume required pursuant to this Section shall not count as #floor area#. Where access improvements are constructed by the owner of the #zoning lot#, each square foot of mass transit access may constitute three square feet of pedestrian circulation space required pursuant to Section 81-45 (Pedestrian Circulation Space), not to exceed 3,000 square feet.
