More than one conditional use on a lot. In the event that more than one conditional use is proposed on a lot, or which, in the opinion of the Board, could reasonably be anticipated to involve more than one conditional use, the more restrictive conditional use standard shall apply. In applying this provision, the Board shall not be limited to the conditions and standards of any one of the conditional uses involved, but may apply a specific standard or condition from either or any of the uses involved. It is not intended that this provision apply to part-time schools on the same lot with and which are conducted as an adjunct or supplement to the activities of a house of worship or religious organization, such as, but not limited to, Sunday schools, nursery schools, catechism, Hebrew schools, adult education and the like, or as an adjunct or supplement to the activities or programs of chartered membership organizations.
