The minimum number of accessory off-street parking spaces shall conform to the requirements of § 210-56 of this article, except that:
A.
The Planning Board, in conjunction with site development plan approval as provided in Article IX of this chapter, may permit a reduction in the number of developed parking spaces where adequate accessible reserve areas are available and designated on the plan as areas for overflow parking.
B.
The Planning Board may reduce the required number of parking spaces upon demonstration by the applicant that number exceeds the requirement for the estimated peak period and a demonstration by the applicant that such reduction would not induce parking on public ways or result in hazardous conditions for vehicles and pedestrians within or proximate to the site. This reduction by the Planning Board may not exceed 25% of the normally required amount. Further, the Board may require that the site plan leave sufficient space for additional parking should future use(s) of the site, as may be anticipated by this chapter, require it.
