Applicants shall provide a list of the reciprocal actions being proposed and the rationale for choosing the particular actions which, in the determination of the applicant, justify the granting of a zoning incentive. Examples of actions which warrant consideration by the Board are:
(1) 
Providing publicly available, non-patron, off-street parking in excess of the minimum number of spaces required by § 208-103. The number of spaces to be provided shall be at least an additional 20% above the required minimum or 10 spaces, whichever is greater.

Parking. Each use shall comply with the off-street parking and off-street loading requirements of §§ 208-103 and 208-104, except that a minimum of 2.25 parking spaces per dwelling unit shall be provided for each multifamily dwelling use. Loading spaces serving multifamily uses shall be located as close as possible to entranceways for the purpose of facilitating the efficient handling of household items such as laundry and groceries. When this chapter imposes a different restriction upon the use of buildings or premises than are imposed or required by §§ 208-103 and 208-104, the provisions of this chapter shall prevail.
(1) 
Surface parking lots.
(a) 
Surface parking must be located between the principal structure and the side and rear lot line, provided that, where no structure exists between the street and the surface parking facility, such facility shall be enclosed by a knee-high wall or row of landscaping. In no case shall surface parking facilities be located within 20 feet of a street line.
[Amended 1-27-2014 by Ord. No. HR-403]
(b) 
On corner lots, the parking shall be located along the street with the lesser amount of commercial and pedestrian activity.
(c) 
Parking areas must be interconnected, to the extent feasible, with parking areas on adjacent properties to facilitate pedestrian and vehicular circulation. When interconnected parking areas are not immediately feasible, the applicant must provide access easements and design the parking area to facilitate future connections.
(d) 
A surface parking lot is not permitted as a standalone use if the property on which it is located abuts or is across the street from a property in the R-1, R-2 or R-3 Residential Zoning District.
[Added 4-28-2008 by Ord. No. HR-370]
(2) 
Structured parking.

Structured parking is encouraged. Structured parking facilities are required to be designed to enhance the pedestrian-friendly streetscape and the character of the surrounding buildings and uses.
(b) 
Facades that are visible from the street or sidewalk shall be complementary to nearby commercial facades in terms of building materials and architectural design. Exterior finish materials shall be of an enduring quality. Synthetic stucco, concrete block and simulated wood products may not be used as primary exterior finish materials. Vehicular entrances to parking structures should be designed using residential or neighborhood commercial architectural treatments such as recesses, peaked roof forms and arches with the intention of minimizing the appearance of a parking garage. The use of chains, bars or similar security devices that are visible from a street shall be prohibited.
(c) 
Any structured parking facility with frontage on a major arterial highway shall contain retail or commercial space along the entire length of each first floor facade which faces a street. Such commercial or retail space may be relieved only by the vehicular entranceway to the garage area.
(d) 
Any structured parking facility with frontage along a street other than a major arterial highway shall not be required to contain retail or commercial space but shall be required to contain facades that enhance the streetscape of the existing neighborhood. Such facades may be relieved only by the vehicular entranceway to the garage area.
(e) 
If the property on which the structured parking is located abuts or is across the street from a property in the R-1, R-2 or R-3 Residential Zoning District, structured parking is not permitted as a standalone use and is permitted as an accessory use only on the ground floor or below.
[Added 4-28-2008 by Ord. No. HR-370]
(3) 
Shared parking. In order to encourage the efficient use of land and resources, applicants are permitted to share off-street parking facilities for mixed-use developments or for uses located sufficiently close to one another that have different peak parking demands or operating hours. In order to utilize this provision, applicants must:
(a) 
Provide a parking demand analysis for each use that exceeds 2,400 square feet of gross floor area for approval by the Township Engineer that demonstrates adequate parking will be provided for the uses on site during peak hours. The analysis should generally be consistent with the published recommendations of the Institute of Traffic Engineers (ITE). Data collected from similar or comparable uses to the proposed use may also be submitted for review. For any change of use involving shared parking, a new parking demand analysis shall be submitted as determined necessary by the Zoning Officer.
(b) 
Demonstrate that the shared parking shall be located no further than 500 feet from the entrance to the buildings and uses they are intended to serve.
(c) 
Provide a written, legally-binding agreement among the owners of record, their tenants, and those with which parking facilities are shared for review and approval by the Township.
E. 
Design standards. Each use shall comply with the following design standards:
(1) 
Front facade.
(a) 
The front facade of any building shall promote an attractive and pedestrian-friendly streetscape. Characteristics to be considered in making such assessment shall include, but not be limited to, style, location, materials, scale and window/door placement. Varied building designs that avoid long flat facades are required.
(b) 
No more than 40 feet of continuous facade shall be created for any new building at the first floor level. Any building which is wider than 40 feet at the first floor level shall have a recess of at least four feet at intervals of 20 feet.
(c) 
A continuous facade shall be created along the sidewalk frontage, except for a first floor break in the street wall that may be created for a vehicular entranceway to a structured parking facility, where such break in the street wall does not exceed 30 feet in width.
(2) 
No building shall be a windowless box. Doors and windows shall constitute no less than 60% of the front façade for buildings containing nonresidential uses.
[Amended 1-27-2014 by Ord. No. HR-403]
(3) 
No building shall have opaque windows.
(4) 
If the first floor front facade is set back from the edge of sidewalk by more than five feet, the area between the front facade and the edge of sidewalk shall be used for enhanced pedestrian spaces and amenities, such as a landscaped plaza or courtyard, a sculpture garden, or other civic-like space accessible to pedestrians.
(5) 
Exterior amenities, to be owned and maintained by the property owner, such as benches, information kiosks, bike facilities, bus shelters and/or publicly-accessible privately-owned plazas, shall be provided on private property or within adjoining public rights-of-way.
