UN
(T-4)
Building Orientation
1
All buildings must be oriented toward a primary public street.
2
All public entrances must include direct pedestrian connections between street facing doors to adjacent sidewalks. All buildings must have a public entrance from the sidewalk along the primary building facade. Public entrances must be visually distinctive from the remaining portions of the facade along which they are located.
3
Garage doors must not be located on the front of buildings, but rather must face the side or the rear of the property. If placement on the front of the building is unavoidable, garage doors must be located a minimum of 15 feet behind the principal building line, and are limited to a total 20 feet in width.
Facade Design
4
Building facades that abut a public right-of-way (excluding alleys) must not contain blank wall areas that exceed 30 linear feet, measured per story parallel to the street.
5
Facades abutting a public right-of-way (excluding alleys) must be divided into multiple "modules," expressed through significant architectural changes such as a change in materials, a change in pattern elements such as fenestration, columns or pilasters, or a change in building setback through recesses or projections. For buildings 150' in length or greater, such modules may be no wider than 50 feet.
6
Public entrances must include design elements to ensure clear visibility and architectural prominence, such as:
a.
Details including but not limited to awnings, arches, friezes, columns, pilasters, transom or sidelight windows mosaic or tile work, murals, or other public art as an integral feature.

Integral landscape or seating elements such as planters and benches or seat walls.
c.
Three-dimensional elements such as corner towers, porticos, arcades or colonnades.
7
Buildings must be designed with consistent building materials and treatments that wrap around all facades visible from a public street. Where material or color treatments change, there should be a significant change in surface plane of a minimum of six inches in difference. Differing materials are encouraged to terminate at inside corners.
8
Facades must express a traditional visual distinction between the ground floor and upper stories through architectural features or detailing, change in materials, or a change in pattern elements such as fenestration. Where existing adjacent buildings contain such horizontal features or datum lines distinguishing the ground floor from upper stories, new building facades must complement the heights of such features to create visual continuity along the face of a block.
9
Commercial storefronts must include traditional pedestrian-oriented elements such as display windows, knee walls, transoms, and/or cornices.
10
All architectural openings, including windows, doorways, arches, porch framing, etc., should be sympathetic to the repetition of prevailing horizontal or vertical elements of the structure.
11
Window shutters, whether functional or used as a decorative element, must be used consistently across the building facade, and must be proportioned so as to cover the window opening when closed.
12
Mechanical equipment and structural components such as vents must be located and screened to minimize visibility.

The ground floor of the front facade must maintain a minimum transparency of 35%, measured between two and 10 feet in height.
14
Upper floors of the front facade must maintain a minimum transparency of 15% of the wall area of the story.
Roof Design
15
Roof forms may include symmetrical pitched roofs or flat roofs with cornice treatments. Slopes of pitched roofs should be no less than 5:12, and that porch roofs should be shed roofs with pitches no less than 3:12.
16
Rooflines of 100' in length or more must be varied through the use of architectural design elements such as dormers, gables, or projected wall features. Such elements of variation may be no wider than 50'.
17
Reflective roof surfaces that produce glare are prohibited, except for cool roofs intended to radiate absorbed or non-reflected solar energy and reduce heat transfer to the building.
18
Where parapet walls are used, they must feature three-dimensional cornice treatments or other shadow-creating details along the top.
Site Design
19
Sites must be designed to ensure safe pedestrian and bicycle access from the public right-of-way, and safe pedestrian and bicycle circulation within the development.
20
A cohesive character must be established through the use of coordinated hardscape (paving materials, lighting, street furniture, etc.) and landscape treatments within the development.
21
Vehicular access to parking and service areas must be provided from an alley wherever possible. This also applies to corner lots served by alley access.

Commercial mixed-use districts development bonus. In order to exceed the maximum building height listed in Table 4-C, a proposed development must meet additional standards listed in this section.
1. 
Height bonus. Up to 15 feet of additional building height may be granted through a voluntary bonus system. To obtain a development bonus, one or more actions in Table 4-D are required.
2. 
Application of bonus points. Bonuses for additional height are subject to the process of this section, and earned and applied as indicated in Table 4-D.
a. 
The Design Review Board will determine the amount of height, up to the maximum of 15 feet, that the development is eligible for. As part of the request for additional height, the applicant must submit mass and scale drawings of the proposed development.
b. 
Following the Design Review Board determination of the eligible amount of height bonus and partial approval of the mass and scale drawings, the approval will be forwarded to the Planning Board. The Planning Board will make a determination that the bonus action(s) proposed by the applicant meet the standards and intent of this section, the zoning district, and this chapter to achieve the height bonus.
c. 
For items 1 and 2 of Table 4-D for affordable housing, the additional height is the full bonus amount (15 feet).
d. 
For items 3 through 7 of Table 4-D, the additional building height is awarded by a point system. Acquired points may be used to increase building height by one foot for each point earned, up to the maximum height bonus the Design Review Board has approved, up to the maximum of 15 feet.

Bonus Action
Bonus Awarded
1
Affordable Housing Option A. Devote 20% of Gross Floor Area (calculated to number of units) for the number of floors above the base maximum height to affordable housing, using local unit size averages. Units must be set aside for households earning 60% AMI or less for a minimum of 30 years.
Example: UC District Maximum Height with Bonus (70' maximum + 15' additional = 85') Additional 15' would typically be used to build one additional floor, so 20% of the units on one floor of the building must be devoted to affordable housing.
Full bonus (15' of height)
2
Affordable Housing Option B. Devote 5% of Gross Floor Area (calculated to number of units) of the total building to affordable housing, using local unit size averages. A minimum of 80% of the affordable units must be set aside for households earning 80% AMI or less, with no more than 20% set aside for households earning between 81% and 110% AMI, for a minimum of 30 years.
Full bonus (15' of height)
3
Provision of Public Civic Space. An additional 5% or more of total lot area is devoted to public civic space above the public civic space required by § 240-9.3.
Up to 5 points
4
High Performance Construction I. Points are awarded on a sliding scale based on level of certification the building is designed to achieve: certified, silver, platinum, gold. Alternatively, up to five bonus points may be awarded for building that is designed to meet or exceed the provisions of the NY Stretch Energy Code, which includes elements more stringent than the base Energy Code that is in effect in NYS at the time of construction. An evaluation from a certified third party that demonstrates that buildings and sites meet LEED certified standards (US Green Building Council); however, LEED certification is encouraged, but not required.

B. 
Gateway commercial districts design standards.
1. 
Design standards.
a. 
The following design standards apply in the gateway commercial districts to new construction and to any additions to a structure existing as of the effective date of this chapter that exceed 30% or more of the existing structure's square footage. Table 4-I: Gateway Commercial Districts Design Standards establishes the design standards for the gateway commercial districts. In the table, a "✓" indicates that the standard is applicable in the district indicated. The absence of a "✓" indicates that the standard does not apply to the district.
b. 
Design standards may be exempted by the Design Review Board or Planning Board as follows:
(i) 
Standards within the category of site design may be exempted by the Planning Board.
(ii) 
Where the Design Review Board reviews and approves development, including but not limited to within the Historic Review Overlay District or Architectural Review Overlay District, the Design Review Board may exempt standards in categories outside of those delineated in Subsection B1b(i) above.
(iii) 
Where the Design Review Board does not review and approve development, the Planning Board may exempt standards in all categories and may request a recommendation from the Design Review Board.
(iv) 
Design standards in the GC-R District may be exempted by the Design Review Board or Planning Board with a written explanation detailing the exemption as follows:
(1) 
The uses in the structure are unique and preclude meeting the rural design standards of the chapter; or
(2) 
The lot configuration is unique and precludes meeting the rural character of the chapter; or
(3) 
That there are extraordinary circumstances unique to the parcel that demonstrate that the design standards cannot meet the rural character objectives of the chapter.
c. 
Single-family, single-family attached, two-family, and townhouse dwellings are not subject to these standards but rather subject to the design standards by dwelling type of Article 8. Multi-family dwellings are subject to the design standards of Table 4-I.
d. 
The area designated as GC-R bound by Crescent Avenue to the north, Route 9 to the west, and lands currently zoned as INST-PR to the east and approximately 3,300 feet to the south shall incorporate the following design standards in addition to the GC-R standards listed below:
(i) 
Pedestrian systems should be trails that link commercial nodes to other use areas (i.e., neighborhoods). Trails shall meet the requirements under § 240-18.5.

Facade Design
1
Building facades that abut a public right-of-way (excluding alleys) must not contain blank wall areas that exceed 30 linear feet, measured per story parallel to the street.
2
Facades abutting a public right-of-way (excluding alleys) must be divided into multiple "modules," expressed through significant architectural changes such as a change in materials, a change in pattern elements such as fenestration, columns or pilasters, or a change in building setback through recesses or projections. For buildings 80' in length or greater, such modules may be no wider than 40 feet.
3
Commercial storefronts must include traditional pedestrian-oriented elements such as display windows, bulkheads, transoms, and cornices.
4
All architectural openings, including windows, doorways, arches, porch framing, etc., must maintain a height equal to or greater than their width to emphasize the verticality of such elements.
5
Window shutters, whether functional or used as a decorative element, must be used consistently across the building facade, and must be proportioned so as to cover the window opening when closed.
6
Buildings must be designed with consistent building materials and treatments that wrap around all facades visible from a public street. Where material or color treatments change, there should be a significant change in surface plane of a minimum of six inches in difference. Differing materials are encouraged to terminate at inside corners.
7
Mechanical equipment and structural components such as vents must be located and screened to minimize visibility.
Fenestration Design
8
The ground floor of the front facade must maintain a minimum transparency of 25%, measured between two and 10 feet in height.
9
The ground floor of the front facade must maintain a minimum transparency of 40%, measured between two and 10 feet in height.
Roof Design
10
Buildings must exhibit a typical rural, pitched roof form, including but not limited to gabled, hipped, gambrel, and barn roof forms.
11
Roof forms may include symmetrical pitched roofs or flat roofs with cornice treatments. Slopes of pitched roofs may not be less than 5:12, except that porch roofs may be sheds with pitches not less than 3:12.
12
Where parapet walls are used, they must feature three-dimensional cornice treatments or other shadow-creating details along their tops.
13
Reflective roof surfaces that produce glare are prohibited, except for cool roofs intended to radiate absorbed or non-reflected solar energy and reduce heat transfer to the building.
Site Design
14
Sites must be designed to ensure safe pedestrian and bicycle access from the public right-of-way, and safe pedestrian and bicycle circulation within the development.
15
Vehicular and pedestrian circulation systems must reflect a rural character through the use of curvilinear forms that acknowledge and work to complement site features such as vegetation and topography.
16
Off-street parking and traffic flow must not interfere with the flow of pedestrian travel or otherwise detract from the aesthetic character of a development or redevelopment. All off-street parking must be screened or aligned so that light from vehicle headlights do not adversely impact abutting properties.
17
Existing on-site vegetation and topography must be preserved to the extent practicable. Where topography must be altered, cut and fill slopes must be graded to mimic existing slopes, at a maximum of 1:5, and blend smoothly into the surrounding landform.
18
Site designs must employ techniques such as variation in the height and placement of buildings, as well as clustering of structures and vegetation to reinforce the rural character of the area, and to help preserve scenic views of the surrounding natural landscape.
19
Shared driveways are strongly recommended with the minimum spacing between adjacent driveways on the same side of the street at 500 feet. Access connections on opposite sides of the street should be aligned or off-set so as to eliminate left-turn conflicts. The Planning Board, as part of site plan review, should evaluate the effect of proposed driveway locations on development of abutting properties. Proposals for shared driveways may require cross access easements.
