All uses that are not expressly permitted in this article are prohibited. An applicant for a nonpermitted use, after application for a permit has been denied, may apply to the Zoning Board of Adjustment and at the same time shall apply to the Planning Board in order that the Planning Board may review and make a recommendation of standards to the Zoning Board of Adjustment in time for the public hearing of the Zoning Board of Adjustment on the applicant's case. The Planning Board may offer an opinion as to whether such proposed new use is compatible with the uses specifically permitted in the limitations for the district in which the applicant's land is located and whether the new use will not seriously impair the intent of this article and of the Master Plan.
