1.  Except as otherwise subsequently provided in this section, the formation of a special district shall not be approved by any board of county commissioners without the resolution of approval and the service plan required by the Special District Control Law. The approved service plan and the resolution of approval shall be incorporated by reference in the ordinance organizing the district after there has been a compliance with all other legal procedures for the formation of the proposed district. If the board of county commissioners fails to approve the service plan for any proposed special district and such failure is determined by any district court in this state for any county in which the district is located to be arbitrary, capricious or unreasonable, the court may order the formation of such district by the board of county commissioners of the county vested with jurisdiction as provided in NRS 318.050 without such resolution of approval; but an acceptable service plan in accordance with the provisions of the Special District Control Law, shall be filed with and approved by the court and incorporated by reference in and appended to the order of the court providing for the organization of the district after there has been a compliance with all other legal procedures for the formation of the proposed district. If the service plan is approved by the board of county commissioners, any interested party as defined in subsection 2 of NRS 308.070, if such party had appeared and presented his or her objections before the board of county commissioners, is entitled to appear and be heard at the hearing of the board of county commissioners so vested with jurisdiction for the organization of the district, and the district court may dismiss any pending legal proceedings contesting the failure of any board of county commissioners to approve a service plan upon a determination that the decision of the board of county commissioners was not arbitrary, capricious or unreasonable.

2.  Upon final approval by a board of county commissioners for the formation of the special district, the facilities, services and financial arrangements of the district shall conform to the approved service plan.

3.  After the organization of a special district pursuant to the provisions of chapter 318 of NRS, material modifications of the service plan as originally approved may be made by the board of such special district only by petition to and approval by the board of county commissioners of each county in which the district is located in substantially the same manner as is provided for the approval of an original service plan, except that the processing fee for such modification procedure shall not exceed $100. Such modifications are required only with regard to changes of a basic or essential nature and are not required for changes of a mechanical type necessary only for the execution of the original service plan.

4.  Any unreasonable departure from the service plan as originally approved, or, if the same has been modified, then from the service plan as modified, may be enjoined at any time by a district court upon motion of any board of county commissioners from which a resolution of approval is required by the Special District Control Law, or upon the motion of any interested party.
