(a) Upon review of a petition, the local soil and water conservation district commissioners may approve designation of an agricultural district. A designated agricultural district shall be established for a period of five (5) years and reviewed for redesignation every five (5) years thereafter. However, the soil and water conservation district may review the status of designation at any time upon the written request and justification of the respective county board of supervisors, city board of aldermen, city council, city selectmen, city commissioners, city manager or mayor or upon a decision of the district commissioners that such a review is appropriate. The soil and water conservation district commissioners may sustain or repeal designation of an agricultural district based upon the following:

(i) The continued viability of the agricultural district. An agricultural district may become reduced in acreage based upon the voluntary withdrawal of any of the ownerships. However, the agricultural district shall cease to exist if the total acreage drops below twenty (20) acres;

(ii) The impacts and consequences of proposed land development; and

(iii) Other factors that the district commissioners may find relevant.

(b) Any ownership, or any successor heir of the ownership, within an agricultural district may withdraw from the agricultural district upon notifying the local soil and water conservation district in writing.

(c) Landowners may submit or resubmit petitions for designation or redesignation at any time to the local soil and water conservation district.

(d) If a petition is rejected or the local soil and water conservation district commissioners repeal designation of an agricultural district, the ownerships within the agricultural district may appeal the decision of the district commissioners to the State Soil and Water Conservation Commission. Based upon a review of all relevant information and following a public hearing, the State Soil and Water Conservation Commission may either sustain or overturn the decision of the local soil and water conservation district.
