A.   Authorizing Variance: Where the subdivider can show that a provision of this title would cause unnecessary hardship if strictly adhered to and where, in the opinion of the council, because of topographical or other conditions peculiar to the site or density, a departure may be made without destroying the intent of such provision, then the council may authorize a variance. Any variance recommended by the commission is required to be entered in writing in the minutes of the commission and the reasoning on which the departure was justified shall be set forth.
   B.   Zoning Compliance: Notwithstanding subsection A of this section, no design provision of this title shall necessarily be applied to plats developed under planned unit zoning, title 11, chapter 9 of this code, or of plats developed under planned residential overlay districts unless cross referenced or unless specifically approved as part of a particular planned project. (2008 Code § 28-4)
