The zones established by this chapter are based on geologic, cultural, and other natural or man-made physical conditions of the Township as identified in the Master Plan of Delaware Township. Any party seeking a change in zone designation shall make a written request, along with the reasons for the request, to the Planning Board. If the Planning Board finds that the information justifies a change in the zone designation, the Board shall take actions necessary to make the change. If the proposed change is in conflict with the Master Plan, the Board shall consider an appropriate amendment to the Master Plan. If the Master Plan is amended, the Planning Board shall submit to the Township Committee for its consideration an appropriate amendment to this chapter. If the Planning Board finds by majority vote that the information justifies a change in a zone designation and no amendment to the Master Plan is needed, the Planning Board shall submit an amendment to this chapter for consideration by the Township Committee.
