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. Each decision shall be
accompanied by findings of fact and conclusions based thereon, together
with the reasons therefor. Conclusions based on any provisions of
any ordinance, 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, and the parties shall be entitled to make
written representations thereon to the Board prior to the final decision
or entry of findings. Where the Board has the power to render a decision
and the Board or the hearing officer, as the case may be, fails to
render the same within the period required for by this chapter, the
decision shall be deemed to have been rendered in favor of the applicant.
