Section 45-437.03 - Impediments to efficient irrigation; substitution of acres; definitionsA. In an irrigation non-expansion area, a person who owns acres of land which are contiguous and which may be irrigated pursuant to section 45-437 may apply to the director to permanently retire a portion of those acres from irrigation and substitute for the retired acres the same number of acres. The director may approve the substitution of acres if the owner demonstrates to the director's satisfaction that all of the following apply: 1. A limiting condition associated with the acres to be retired from irrigation substantially impedes the implementation of more efficient irrigation practices on the legally irrigated acres.2. The substitution of acres will substantially reduce the limiting condition and will substantially facilitate the implementation of more efficient irrigation practices.3. The substitute acres are within the same farm unit as the legally irrigated acres that will not be retired.4. The substitution will not reduce the number of acres of land within the farm unit that are eligible to receive central Arizona project water.5. If the acres to be retired are located within the exterior boundaries of an irrigation district, the substitute acres will be located within the exterior boundaries of the same irrigation district.6. The area of land within the substitute acres that is physically capable of being irrigated at the time the application for substitution of acres is filed does not exceed the area of land within the acres to be retired that is physically capable of being irrigated at the time the application for substitution of acres is filed.B. For purposes of this section: 1. "Legally irrigated acres" means acres of land which are contiguous and which may be irrigated pursuant to section 45-437.2. "Limiting condition" means any condition that limits the achievement of more efficient irrigation on the legally irrigated acres, including irregularly shaped legally irrigated acres and poor quality soils.
