If any application for subdivision approval hereunder contains any lot with a minimum area of less than four acres, the applicant shall also submit a document to be entered of public record, restricting in perpetuity further subdivision of any lot containing six acres or more in such subdivision; such document, creating the restriction, shall be fully executed and approved as to form by the Township Solicitor prior to final approval of the subdivision.
