The Board of Trustees may, on its own motion or on petition or on recommendation of the Planning Board or the Board of Appeals supplement or repeal the regulations of this chapter or amend this chapter as provided in Village Law. Every such proposed amendment or change, however, shall first be referred to the Planning Board for study, public hearing and recommendation.

In their interpretation and applications, the provisions of this chapter shall be held to be the minimum requirements adopted for the promotion of the public health, morals, safety or the general welfare. Whenever the requirements of this chapter are at variance with the requirements of any other lawfully adopted rules, regulations or ordinance, the most restrictive, or that imposing the highest standards, shall govern.

In the event that a site plan involves a need for a variance or special use permit, an application for the site plan shall be submitted to the Planning Board prior to submission to other boards. The Planning Board shall convey any information or documents which it deems appropriate to the applicable board, with respect to the variance or special use permit requested, and the Planning Board may convey any opinions or recommendations which it may have with respect to the application. If the appropriate board grants the variance or special use permit, the applicant may seek final approval of the site plan.
