a. 
Building heights shall be varied within the development.
b. 
Buildings of greater than three stories adjacent to residential districts shall be of varying size and heights and with varying setbacks so as to avoid long building lines, which tend to act as a barrier.
c. 
The common open space available for public use shall be designed to include a setting for outdoor cultural or entertainment activities.
d. 
The common open space available for public use shall connect with existing or planned adjacent pedestrian ways, plazas, and other open space and shall be readily accessible to the public. Open walkways between building masses to access common open space shall be encouraged.
e. 
All building facades shall have full architectural treatment and architectural elements, equivalent in quality to those on the facade on the front entrance and landscaping so as to avoid monotony and enhance their visual appeal. Windows shall be provided on all sides of the building.
[Ord. No. 2011-16, § 2.]
In AET districts, accessory off-street parking spaces shall be provided for all construction and for conversions, and accessory off-street loading berths, open or enclosed, shall be provided for new permitted nonresidential uses, in accordance with the regulations set forth and referred to in this part, except that loading berths are not required for education buildings and other nonresidential buildings on lots greater than one acre. All such parking spaces (except higher educational institutions, which shall be governed by subsection (b) of this section, below) and loading berths shall be subject to the provisions of section 10B-282, et seq., of this article.
Parking spaces made available to the proposed use whether within the AET or adjacent zoning districts shall be included in the calculation of parking spaces provided for a proposed use. In addition, shared use of parking spaces for different uses, e.g., theater use would use parking spaces in the evening that would be available to a commuter use during the daytime, shall be encouraged, and shared parking spaces shall be counted for each such use in determining compliance with the parking space requirements in AET districts in accordance with accepted standards and methodologies for shared parking analysis. These methodologies consist in applying a percent presence ratio for each critical time period to the respective parking and zoning ratio of each proposed use. Applicant shall produce a matrix showing this calculation for each use and each typical critical time period. The total parking demand for the time period with the highest sum of the parking demands for each use shall be used as the required parking supply. The shared parking methodology can also be used for a single proposed use whereby the applicant can demonstrate that for certain critical time periods for that use there is a guaranteed supply of available parking spaces in nearby parking facilities.
Commuter parking shall be provided within the AET Zone in the Township or E5 Zone in Princeton Borough on parcels held in common ownership within a multi-lot project or on lots adjacent thereto, and consistent with any then existing agreements between the property owner and the rail service operator. Train stations for heavy rail service to/from Princeton Junction shall have within 1,000 feet thereof a minimum of 180 parking spaces for monthly permit, daily meter and partial-day users within the project parcel or lots adjacent thereto, which spaces shall be considered in the shared parking provisions of this section after 7:00 p.m. and on weekends. Special provisions shall provide for twenty-four-hour, forty-eight-hour, and seventy-two-hour overnight permits. Parking spaces for kiss and ride users shall be provided adjacent to the rail station and shall not be used to satisfy the minimum 180 space requirement.

The educational institution shall also certify the percentage of eligible graduate students. The sum of all faculty and staff employed in the subject structure and all eligible graduate students assigned to that structure constitutes the commuting population employed in or assigned to the structure.
a. 
For each 1.25 commuting population employed or assigned to the structure, one parking space shall be provided within the AET district, or within campus facilities in the adjoining E-1 or E-2 districts or in adjoining municipalities. Visitor parking is included in determining this ratio.
b. 
For places of public assembly, such as lecture halls of over 100 seats, auditoriums, theatres, chapels or gymnasiums, but not including libraries or dining halls, one space shall be provided for each five seats. Parking spaces provided for normal daytime activity for other purposes shall be considered to be available for such public uses as are normally conducted in the evening or weekends.
c. 
At least once a year following approval of a structure, every educational institution shall certify to the development enforcement officer the aggregate number of employees (faculty and staff) and eligible graduate students. Whenever that number exceeds the number certified at the time of application, the development enforcement officer shall notify the board of original jurisdiction, if there was one, and recommend such additional parking spaces as may be required. In the case of prior approval by a board of jurisdiction, such board shall reopen the application, and the educational institution shall propose such changes to the approved site plan as are necessary to provide the additional parking spaces in accordance with the standards as to the number, location, and design of such spaces set forth in this article. In the case of prior approval by the development enforcement officer, such officer shall require that the educational institution provide the additional parking spaces in accordance with the standards as to the number, location, and design of such spaces set forth in this article, and the institution shall promptly do so. With every application for development, the applicant shall submit an affidavit that it has submitted all the certifications required by this section for all property within the township under its ownership or control. No application for development shall be deemed complete if the applicant fails to submit such affidavit or if the certifications required by this section have not been submitted.
