The Board or the hearing officer, as the case may be, shall render a written decision or, when no decision is called for, make written findings on the application within 45 days after the last hearing before the Board or hearing officer. Where 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 this chapter or the Planning Code, or any rule or regulation, shall contain a reference to the provision relied on and the reasons why the conclusion is deemed appropriate in the 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 within 45 days, and the parties shall be entitled to make written representations thereon to the Board prior to final decision or entry of findings, and the Board's decision shall be entered no later than 30 days after the report of the hearing officer. Where the Board fails to render the decision within the period required by this chapter or the Planning Code, or fails to hold the required hearing within 60 days from the date of the applicant's request for a hearing, 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. When 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 in the same manner as provided in Section 908(1) of the Pennsylvania Municipalities Planning Code. Nothing in this subsection shall prejudice the right of any party to appeal the decision to a court of competent jurisdiction.
