§ 155-4.3 Commercial Center NC, VC and TC Districts.

[Amended 7-21-2021 by Ord. No. 4223; 2-15-2023 by Ord. No. 4260]

The intent of the Neighborhood Center (NC), Village Center (VC), and Town Center (TC) Districts is to preserve and enhance the multifaceted uses of the Township's established commercial areas by graduating the intensities thereof, with NC being the least intensive in terms of usage and density, VC being of moderate intensity in terms of usage and density, and TC being the most intensive in terms of usage and density and consisting of commercial, residential, and mixed uses. NC and VC Districts are the small commercial areas that function as neighborhood or village centers, generally compact, walkable in scale, with local retail, and occasional residential uses above the first floor. The purpose of the NC and VC Districts is to preserve and enhance small commercial centers that serve and are bounded by residential neighborhoods. TC Districts are the medium to larger commercial areas, related to major transportation corridors, mixing local, regional and national retail, with some residential uses above the first floor. The TC1 Districts are the Township's traditional shopping districts that developed around train stations and grew as corridors over time. These are pedestrian-oriented with buildings entered from street-front sidewalks, with a variety of retail and service uses, and may include shared and municipal parking. The TC2 Districts are corridor extensions of TC1 Districts, with varied front setbacks that serve as a transitional zone.

Lot occupation:

Lots shall comply with standards in § 155-3.4, Lot occupation.

Building frontage shall be according to Table 4.3, Commercial Center Form Standards.

Street screens.

Street screens shall be located along the same plane as the building façade or elevation.

Projections shall be allowed as specified in § 155-3.6, Projections.

Building height shall be as specified in § 155-3.3, Building height, and shall be as shown in Table 4.3, Commercial Center Form Standards.

The first floor elevation of a building at a frontage shall be established at the midpoint of the front property line, and may extend a maximum of 2.5 feet above the lowest point of the sidewalk grade. A finished floor elevation more than 2.5 feet above the lowest point of the sidewalk grade shall be considered the second floor. At building interior, side or rear dimension from grade to first floor may range.

In determining the mean level of the ground or the lowest level of the ground surrounding the building, the following may be excluded: openings in the foundation wall which provide for ingress and egress and/or light and air; openings up to 25 feet in length providing access to required underground parking spaces; openings required to comply with the building exit provisions in the Building and Fire Codes; and, openings required for ventilation wells or shafts to comply with the Mechanical Code.

Chimneys, enclosed stairwells, roofed and unenclosed roof terraces and roof trellises, spires and uninhabitable ornamental building features may be allowed to exceed maximum building height up to an additional 12 feet and occupy a maximum 20% of roof area.

The developer shall contribute a sum of money equal to 5% of the construction costs of the building. This fund shall be controlled by the Township and be dedicated to use for moderate-income housing units as described in § 155-10.13, Moderate-income housing. The method of payment of this contribution shall be established during the land development approval process.

The height of a nonresidential building in TC1 may be increased to a maximum of four stories, provided that public gathering space in compliance with § 155-4.3C(5)(a) is provided.

A minimum of 2,000 square feet of dedicated contiguous public gathering space is provided for any lot with less than 20,000 square feet of land area. A minimum of 10% of the total lot area shall be dedicated to contiguous public gathering space for lots over 20,000 square feet. Land area dedicated to public ingress/egress easements shall not be included in the total lot area calculation for demonstrating compliance with the 10% of public gathering space requirement.

§ 155-4.4 Institutional districts.

Intent. The intent of the institutional districts is to provide a regulatory context for institutional uses, with two main goals: to support the sustainability of institutions, and to render them compatible with the residential neighborhoods in which they may be located. These regulations recognize a diversity of institutional locations and goals, the institutional need to adapt to changing circumstances (including functions and growth), and neighborhood desires to minimize incompatibilities (including activities and expansion).

Districts. There are four principal institutional districts: Institutional Nature Preserve (IN), Institutional Civic (IC), Institutional Education (IE), and Institutional Housing (IH). These categories correspond to the variety of activities and range of impacts that might be expected of each. The Institutional Civic (IC), Institutional Education (IE), and Institutional Housing (IH) Districts are divided into subdistricts with varying development standards designed to assure compatibility with adjacent residential development. See Table 5.2, Uses for Institutions, for specific uses permitted in each district.

Institutional Nature Preserve (IN) is intended to collectively define sites and buildings operated for types of uses including but not limited to cemeteries, environmental and open space preserves, golf clubs, and institutional residential.

Institutional Civic (IC1, IC2, IC3) is intended to collectively define communally beneficial land uses, including but not limited to organizations dedicated to the arts and culture, social and religious use, senior housing, wellness and recreation.

Institutional Education (IE1, IE2, IE3) is intended to collectively define sites or buildings operated for the provision of full-time or part-time educational services for students of all ages.

Institutional Housing (IH1, IH2, IH3) is intended to collectively define sites or buildings operated for the provision of housing and health and long-term care for the elderly and people with disabilities.

Applicability.

Property zoned institutional shall be developed according to the applicable requirements of each individual institutional district and each institutional subdistrict.

Institutional district regulations apply to all institutional uses according to the definitions, and Table 5.2, Uses for Institutions.

An institutional district property shall conform to the requirements of this article.

All properties in the institutional district shall conform to Article IV, District Specific Standards, Article V, Uses, Article X, Supplemental Use Regulations, Article XI, Process and Procedures, of this chapter and Chapter 135, Subdivision and Land Development, Article III, Plan Filing, Processing and Review.

[Amended 5-18-2022 by Ord. No. 4244]

Changes to the institutional primary use of a property located within an existing institutional district shall conform to the requirements of this article.

(6)

All previous conditions imposed by the Zoning Hearing Board on the approval of institutional uses by special exception and all imposed conditions by the Board of Commissioners by conditional use shall remain in force but may be modified by conditional use. All previous conditions imposed by the Board of Commissioners on the grant of land development approval for institutional uses shall remain in force but may be modified by the Board of Commissioners, by amendment of the land development approval.

(7)

Public schools may be located in every zoning district. In LDR and MDR Districts, Institutional Civic (IC), and Institutional Housing (IH) Zoning Districts, public schools shall be developed according to the requirements of the Institutional Educational District, IE2, Table 4.4.3.B. In all other zoning districts, public schools shall be subject to the regulations of that district.
