The applicant demonstrates that the number of off-street parking spaces is adequate for a proposed use.
(2) 
On-street parking is available within a reasonable distance.
(3) 
Off-street parking in public lots is not available.
(4) 
Granting the waiver will not create excess congestion, hazardous, or unsafe conditions in the neighborhood.

All driveway entrances and exits shall be kept free from visual obstructions higher than three feet above street level for a distance of 15 feet measured along the intersecting driveway in order to provide the required visibility for entering and exiting vehicles. Continuous internal walkways shall be provided from the public sidewalk to the principal customer entrances, connecting pedestrian activity. All internal pedestrian walkways shall be distinguished from driving surfaces through use of durable surface materials to enhance safety and comfort, as well as the attractiveness of the walkways.
D. 
Lighting. Artificial lighting used to illuminate parking spaces shall be arranged so that no direct rays from such lighting falls upon neighboring properties.

G. 
Shared parking. The Planning Board may allow a reduction in the off-street parking requirements for properties that share parking. To obtain such an approval, the applicant must conclusively demonstrate that one or more proposed uses will generate a demand for parking spaces primarily during periods when the other use or uses are not in operation.
H.

I. 
In the MB District, parking shall be located to the side and rear of buildings.
J. 
Parking held in reserve. If the applicant can clearly demonstrate to the Planning Board that, because of the nature of the operation or use, the parking or loading requirements of this chapter are unnecessary or excessive, the Planning Board shall have the power to approve a site plan showing less parking or loading area than required; provided, however, that a landscaped area of sufficient size to meet the deficiency shall be set aside and reserved for the purpose of meeting future off-street parking and loading requirements in the event that a change of use of the premises shall make the use of such additional off-street facilities necessary. The applicant, at the time of the initial application, shall submit for Planning Board approval a design of this possible future parking area. The reserved area shall be converted to parking in whole or in part whenever the owner desires, or when deemed necessary by the Planning Board. In addition, a reevaluation of the parking requirement shall be required upon a change of use, expansion, or renovation. Notations describing these arrangements shall be included on the face of the plan.
