(C) The Tower Portion of a project shall have a horizontal separation of at least 30 feet from any Mid-Rise Portion on the same development lot, except that a bridge between the Tower Portion and the Mid-Rise Portion may be permissible up to a height of 130 feet if the bridge is no more than one story in height, is set back a minimum of 15 feet from any property line, and is visually subordinate to the buildings it connects.
