Upon review, the City Council may affirm, remand, reverse, or modify in whole or part a determination or requirement of the decision that is under review. When the City Council modifies or renders a decision that reverses a decision of the review body, the City Council shall set forth its findings and state its reasons for taking the action. When the City Council elects to remand the matter back to the previous review body for such further consideration as the City Council deems necessary, it may include a statement explaining the error found to have materially affected the outcome of the original decision and the action necessary to rectify such.
