The Board or the hearing officer, as the case may be, shall render a written decision or, if no decision is called for, provide written findings on the application within 45 days after the last hearing before the Board or hearing officer. If the application is contested or denied, each decision shall be accompanied by findings of fact and conclusions based thereon, together with the reasons therefor. Conclusions based on any provisions of the chapter or any other ordinance, rule or regulation shall contain a reference to the provisions relied upon and the reasons why the conclusion is deemed appropriate in light of the facts found. If the hearing is conducted by a hearing officer, and there has been no stipulation that his decision or findings are final, the Board shall make his report and recommendations available to the parties of record within 45 days. The parties shall be entitled to make written representations thereon to the Board prior to final decision or entry of findings, with the Board's decision entered no later than 30 days after the report of the hearing officer. If the Board fails to commence, conduct or complete the required hearing as provided for under § 27-1406, Subsection 1D, the decision shall be deemed to have been rendered in favor of the applicant, unless the applicant has agreed in writing or on the record to an extension of time. If a decision has been rendered in favor of the applicant because of the failure of the Board to meet or render a decision as herein above provided, the Board shall give public notice of said decision within 10 days from the last day it could have met to render a decision in the same manner as provided under § 27-1406, Subsection 1A, and written notice of the decision shall be mailed to those parties identified under § 27-1406, Subsection 1B. If the Board fails to provide such notice, the applicant may do so. Nothing contained within this section shall prejudice the right of any party opposing the application to appeal the decision to a court of competent jurisdiction.
