Whenever any subdivision of land is proposed, and before any permit for the erection of any structure in such proposed subdivision shall be granted, the subdivider, owner or his authorized agent shall secure approval from the city officers and agencies in accordance with the procedures set forth below. When deemed unnecessary by the director of public works under the circumstances of a specific subdivision, he may waive such of the formally required procedural steps or other requirements provided for herein as deemed by the director of public works to be unnecessary under such circumstances; provided, however, that waiver of any specific requirement shall not prevent the public works director or his designee, or the planning and zoning commission, or the city council from later requiring such specific requirement(s) in the event it is later determined necessary under the circumstances. The waiver of any such procedural or other requirement in any given circumstance shall not constitute precedence in respect to any other circumstances, and every subdivision shall be considered upon the individual circumstances for such purpose. (2005 Code)
