In considering a tentative map for a condominium, stock cooperative, or community apartment project, or for any subdivision wherein physical constraints or the extraordinary amenities to be provided render application of the design and improvement standards of this title inappropriate, the advisory agency, with the concurrence of the city engineer, may agree to the substitution of alternate design and improvement standards which do not literally comply with the requirements of these subdivision regulations but which serve to facilitate the ultimate development of the property in a manner that will be consistent with the general plan. (Ord. 3515 § 1, 1993)
