[Added 12-28-2011 by G.O. No. 5-2011]
The following districts comprise the downtown districts:
A. 
D-MX Mixed-Use District. The D-MX Mixed-Use District is a high concentration of commercial, residential and institutional developments in the downtown. The D-MX District encourages ground-floor commercial uses to activate the street-level environment. In order to create a concentration of pedestrian-oriented commercial uses networked throughout the D-MX District, certain streets are designated "key streets" and require commercial ground-floor uses within a storefront design.
(1) 
Key streets. The key streets of the D-MX District are shown in Map A: Key Streets.[1] The purpose of key streets is to preserve and enhance the pedestrian-oriented commercial environment and promote economic development focused on active uses such as retail, restaurant, service and entertainment uses. To achieve this, regulations require certain ground-floor uses, a storefront design at the street level, and increased transparency requirements. The following streets are designated as key streets in the D-MX District:
(a) 
Main Street between Buena Vista Avenue and Getty Square/North and South Broadway.
(b) 
New Main Street between Getty Square/North and South Broadway and Vark Street/Park Hill Avenue.
(c) 
Nepperhan Street between Buena Vista Avenue to Warburton Avenue.
(d) 
Dock Street from Buena Vista Avenue to Warburton Avenue.
(e) 
Riverdale Avenue/Warburton Avenue between Prospect Street and Wells Avenue.
(f) 
South Broadway/North Broadway between Nepperhan Avenue and Manor House Square.
(g) 
Palisade Avenue between Main Street/Getty Square and Elm Street.
B. 
D-IRT Downtown Industrial Research and Technology District. The D-IRT District supports the industrial uses in the northern portion of downtown. This district with its close proximity to the Metro-North and Amtrak train lines is a prime location for office, industrial, research and development and technology-based uses. It also allows certain commercial uses to serve the work force. Residential uses are prohibited to avoid conflicts with industrial users and encroachment into industrial land.
C. 
UR-LD Low-Density Urban Residential District. The UR-LD Urban Residential Low-Density District is intended to address urban neighborhoods, adjacent to the downtown, that contain a mix of single-family, detached and attached two-family, and townhouse dwellings. The UR-LD District is intended to maintain the residential environment of these urban neighborhoods, continuing the development patterns of these areas established in mid-to-late-nineteenth and early-twentieth centuries.
D. 
UR-MD Medium-Density Urban Residential District. The UR-MD Urban Residential Medium-Density District is intended to address urban neighborhoods, adjacent to the downtown, that contain a mix of all dwelling types, including apartment house dwellings. The UR-MD District is intended to maintain the residential environment of these urban neighborhoods, continuing the development patterns of these areas established in mid-to-late-nineteenth and early-twentieth centuries.
E. 
UR-HD High-Density Urban Residential District. The UR-HD Urban Residential High-Density District encourages a high-density residential development, located adjacent to the downtown to increase the downtown residential population, build a critical mass for the commercial uses located downtown and take advantage of existing transportation resources. Limited commercial establishments are also allowed at select locations within the district.
A. 
Principal uses. The schedule of principal uses permitted within the downtown districts is shown in Table 43-6, Schedule of Principal Uses and UR-HD Accessory Uses.[1] Principal uses are allowed as permitted (P), permitted with supplemental standards (Ps) or special uses (S). In addition, the following use regulations apply:
(1) 
Within the D-MX District, certain uses are required on the ground floor of key streets in order to create a concentration of pedestrian-oriented uses. See § 43-219A(1) and Map A[2] for key street designations. Table 43-6, Schedule of Principal Uses and UR-HD Accessory Uses shows those uses that are required on the ground floor of buildings along the key streets.
(2) 
Within the UR-HD District, limited commercial uses are allowed on the ground floor of apartment houses for lots that front on Riverdale Avenue. (NOTE: The nonresidential uses allowed on the ground floor of apartment houses that front Riverdale Avenue are accessory uses to the residential uses permitted in the UR-HD District.) Table 43-6, Schedule of Principal Uses and UR-HD Accessory Uses shows the nonresidential uses that are allowed along that frontage. Such nonresidential uses must comply with the following conditions:
(a) 
Such uses must be conducted entirely inside a building.
(b) 
Such uses must front on Riverdale Avenue and provide access to the commercial uses from Riverdale Avenue only.
(c) 
No more than one wall sign on the exterior of the structure for each commercial use is permitted. Such wall sign is limited to letters no more than 12 inches in height and a total sign length that equals 70% of the width of the store's Riverdale Avenue facade.
(d) 
Window signs are permitted and limited to no more than 25% of each window and door area.
(e) 
New construction requires a minimum first floor height of 12 feet and fifty-percent transparency of the first floor facade. A minimum eighteen-inch-high knee wall is required beneath glazing. Knee walls are limited to a maximum height of 36 inches.
(f) 
Any security gates must comply with the design standards for security gates in the downtown districts for nonresidential and mixed-use buildings. Security gates are discouraged in the downtown districts and are not required during any rehabilitation of a building or for new construction.

Interior landscape is required for off-street parking lots of 20 or more spaces.
[3] 
All planting materials used must be of good quality and meet the American Standard for Nursery Stock, latest edition, as published by the American Nursery and Landscape Association, hereafter referred to as "ANLA," for sizes, grading, root spread, dimension of root ball, and quality. The use of native species is encouraged. Size and density of plant material, both at the time of planting and at maturity, are additional criteria to be considered when selecting plant material. All landscape must use noninvasive species.
[4] 
All landscape materials must be installed in accordance with the current planting procedures established by ANLA. Planting material should be grown in a climate similar to or more severe than that of the City of Yonkers, typical of its species in branch structure, free of cultural or mechanical injury, insect eggs or their larvae and plant diseases, and is accompanied by certification of inspection from authorities having jurisdiction over use and shipment. All plant material must be installed so that soil is of sufficient volume, composition and nutrient balance to sustain healthy growth.
[5] 
All landscape must be maintained in good condition, present a healthy, neat and orderly appearance, and be kept free of weeds, refuse and debris.
(b) 
Perimeter landscape. A perimeter landscape yard is required for all off-street parking lots, and the landscape treatment must run the full length of the parking lot where it abuts a street, excluding driveways and access points. The perimeter parking lot landscape yard must be improved as follows:

[4] 
All perimeter parking lot landscape areas must be protected with raised concrete, Belgian block or granite curbs.
(c) 
Interior landscape. For off-street parking lots consisting of 20 or more spaces, interior parking lot landscape is required.
[1] 
One parking lot island must be provided between every 10 contiguous parking spaces. As part of site plan approval, parking lot island locations may be varied based on specific site requirements or design scheme, to be approved as part of the landscape plan, but the total number of islands must be no less than the amount required: one island for every 10 spaces.
[2] 
In addition to parking lot islands, additional landscaped areas must be provided within the interior of parking lots. All rows of parking spaces must terminate in a parking lot island or landscaped area. The minimum landscaped area, including parking lot islands, is 10% of the parking lot area. Perimeter parking lot landscape is not considered part of the ten-percent calculation and is not included in the area used to calculate the required 10%.
[3] 
Parking lot islands or landscaped areas must be at least 125 square feet in area. However, parking lot islands must be the same dimension as the parking stall. Double rows of parking must provide parking lot islands that are the same dimension as the double row.
[4] 
Parking lot islands or landscaped areas must be at least six inches above the surface of the parking lot and protected with concrete, Belgian block or granite curbing, except where designed to apply sustainable techniques allowing the flow and access of stormwater. Such islands and landscaped areas must be properly drained and irrigated as appropriate to the site conditions to ensure survivability.
[5] 
Shade trees must be the primary plant materials used in parking lot islands and landscaped areas. One shade tree is required for every parking lot island or landscaped area. If the island extends the width of a double row, then two shade trees are required.
[6] 
Shrubs must be planted within the parking island to provide a second layer of planting for visual interest.
[7] 
A minimum of 75% of every parking lot island must be planted in live ground cover, perennials or ornamental grasses. Mulch is required to fill in planting areas for early growth protection until the ground cover is established and covers the planting area. It is encouraged to mulch bare areas for three to five years, or until the plant material is fully established in the parking islands.
[8] 
Plant materials must not be installed to create visibility concerns for automobiles and pedestrians.

Parking structures.
(1) 
Ground-floor uses.
(a) 
Parking structures on key streets (Map A)[1] shall maintain ground-floor uses as required in Table 43-6, Schedule of Principal Uses.[2]
[2]
Editor's Note: Table 43-6 is included at the end of this chapter.

FIGURE 33: PARKING GARAGE GROUND-FLOOR USES
(2) 
Parking ramps.
(a) 
On parking structure facades that front on key streets, the exterior articulation of internal vertical vehicle circulation, such as ramped portions of the structure used to access higher parking levels, are prohibited. Where internal ramps front on public streets, facade design and screening shall be required to mask the internal ramps.
(b) 
On parking structures that front other streets within the downtown districts, the exterior articulation of internal vertical vehicle circulation, such as ramped portions of the structure used to access higher parking levels, are discouraged. Where internal ramps front on other public streets, facade design and screening is encouraged to mask the internal ramps.

(3) 
Facade design.
(a) 
The design of the facade that fronts on a public street shall include horizontal design elements, such as knee walls and cornices, which reflect the design of other structures in the downtown districts.
(b) 
On portions of the ground floor facade where parking spaces are visible, a decorative screen shall be required above the knee wall to screen traffic and pedestrians in the public right-of-way from headlight glare. The total height of the knee wall plus the decorative screen must be a minimum of four feet.
(c) 
A parking structure accessory to a principal building shall be constructed with materials and design elements that reflect the principal building.
(d) 
For parking structures with rooftop open-air parking, a parapet wall of four feet shall be required. Additional screening of rooftop open-air parking is encouraged in addition to the parapet wall.
C. 
Mechanical parking. All mechanical parking shall be located completely within a structure and meet the design standards for parking structures.
D. 
Curb cuts and access.
(1) 
Any new curb cuts proposed after the adoption of the downtown districts, (December 28, 2011), requires site plan review and approval. Site plan review will consider the following site design standards in the review and approval of new curb cuts:
(a) 
The location of new curb cuts will minimize potentially dangerous traffic movements and will not create a hazard for pedestrians.
(b) 
The property owner has considered the use of alternate methods as a means to minimize curb cuts, including, but not limited to, cross-access easements and shared parking.
(c) 
New curb cuts are discouraged on key streets (Map A)[3] and may be permitted only after proof of efforts at access by curb cuts on other streets has been considered.
(2) 
Single-family and two-family detached and attached dwellings located on corner lots must provide parking access from the side front setback. For the purposes of this provision, the side front setback is defined as the longer front setback. Access must be designed to minimize curb cuts along front setbacks along the block face.
E. 
Cross-access easements.
(1) 
Uses with adjacent parking areas are encouraged to provide a cross-access to allow circulation between sites. Joint-use driveways are encouraged where feasible. If cross-access is provided, as a condition of its approval, the approving agency requires a legal instrument satisfactory to the Corporation Counsel of the City of Yonkers assuring the continued existence and use of such cross-access with the uses and structures that it serves.
(2) 
Cross-access easements must incorporate the following:
(a) 
Internal circulation allows the smooth circulation of traffic between both parking lots and safe access to and from the street.
(b) 
Driveways shall meet City standards. No driveway may exceed 24 feet in width.
(c) 
Bump-outs and other design features are required to make it visually obvious that the abutting properties are tied together.
(d) 
A site plan is required for coordinated or shared parking areas.
(3) 
Property owners who establish cross-access easements must:
(a) 
Record an easement allowing cross-access to and from properties served by the joint-use driveways.
(b) 
Record a joint maintenance agreement defining the maintenance responsibilities of each property owner.
