Decision. Within 60 days following the conclusion of the public hearings, the Borough Manager shall, by official written communication, either grant tentative approval of the development plan, as submitted; grant tentative approval of the development plan, subject to specified conditions not included in the development plan as submitted; or deny tentative approval. Failure to act within said period shall be deemed to be a grant of tentative approval of the development plan as submitted. In the event, however, that tentative approval is granted subject to conditions, the landowner may, within 30 days after receiving a copy of the official written communication of the Borough, notify the Borough of his refusal to accept all said conditions, in which case, the Borough shall be deemed to have denied tentative approval of the development plan. In the event that the landowner does not, within said period, notify the Borough of his refusal to accept all said conditions, tentative approval of the development plan, with all said conditions, shall stand as granted. The decision will be filed with the Secretary of the Borough and the applicant. The decision shall include an approved schedule of final plan application filing which shall not be less than three months from the tentative approval date.
