Sec. 29-14. Applicability.
   (a)   These regulations apply to all lots or parcels of land existing as of April 25, 1991, that are adjacent to the washes listed in table 1.
   (b)   These regulations do not apply to the following:
   (1)   A lot or parcel existing on April 25, 1991, to be developed with one (1) single- family residence or single-family residence accessory structure.
   (2)   A subdivision plat, development plan, or site plan approved prior to April 25, 1991, provided that construction occurs within five (5) years of the effective date of this article [April 24, 1991].

Notice and hearing for adoption of an ordinance establishing the applicability of these regulations to annexed areas shall be in the same manner as for adoption of an ordinance establishing original zoning boundaries for newly annexed areas.
