1. The board of county commissioners of any county may by ordinance, but not as in a case of emergency, impose a tax for infrastructure pursuant to this section and NRS 377B.110.
2. An ordinance enacted pursuant to this chapter may not become effective before a question concerning the imposition of the tax is approved by a two-thirds majority of the members of the board of county commissioners. Any proposal to increase the rate of the tax or change the previously approved uses for the proceeds of the tax must be approved by a two-thirds majority of the members of the board of county commissioners. The board of county commissioners shall not change a previously approved use for the proceeds of the tax to a use that is not authorized for that county pursuant to NRS 377B.160.
3. An ordinance enacted pursuant to this section must:
(a) Specify the date on which the tax must first be imposed or on which an increase in the rate of the tax becomes effective, which must occur on the first day of the first month of the next calendar quarter that is at least 120 days after the date on which a two-thirds majority of the board of county commissioners approved the question.
(b) In a county whose population is 700,000 or more, provide for the cessation of the tax not later than:
(1) The last day of the month in which the Department determines that the total sum collected since the tax was first imposed, exclusive of any penalties and interest, exceeds $2.3 billion; or
(2) June 30, 2025,
whichever occurs earlier.
4. Notwithstanding the provisions of an ordinance described in subsection 3, in a county whose population is 700,000 or more, the tax may continue to be imposed after the date set forth in the ordinance for the cessation of the tax if the board of county commissioners determines by an affirmative vote of at least two-thirds of its members that the cessation of the tax is not advisable.
5. The board of county commissioners in a county whose population is 700,000 or more and in which a water authority exists shall review the necessity for the continued imposition of the tax authorized pursuant to this chapter at least once every 10 years.
6. Before enacting an ordinance pursuant to this chapter, the board of county commissioners shall hold a public hearing regarding the imposition of a tax for infrastructure. In a county whose population is 700,000 or more and in which a water authority exists, the water authority shall also hold a public hearing regarding the tax for infrastructure. Notice of the time and place of each hearing must be:
(a) Published in a newspaper of general circulation in the county at least once a week for the 2 consecutive weeks immediately preceding the date of the hearing. Such notice must be a display advertisement of not less than 3 inches by 5 inches.
(b) Posted at the building in which the meeting is to be held and at not less than three other separate, prominent places within the county at least 2 weeks before the date of the hearing.
7. Before enacting an ordinance pursuant to this chapter, the board of county commissioners of a county whose population is less than 700,000 or a county whose population is 700,000 or more and in which no water authority exists, shall develop a plan for the expenditure of the proceeds of a tax imposed pursuant to this chapter for the purposes set forth in NRS 377B.160. The plan may include a regional project for which two or more such counties have entered into an interlocal agreement to expend jointly all or a portion of the proceeds of a tax imposed in each county pursuant to this chapter. Such a plan must include, without limitation, the date on which the plan expires, a description of each proposed project, the method of financing each project and the costs related to each project. Before adopting a plan pursuant to this subsection, the board of county commissioners of a county in which a regional planning commission has been established pursuant to NRS 278.0262 shall transmit to the regional planning commission a list of the proposed projects for which a tax for infrastructure may be imposed. The regional planning commission shall hold a public hearing at which it shall rank each project in relative priority. The regional planning commission shall transmit its rankings to the board of county commissioners. The recommendations of the regional planning commission regarding the priority of the proposed projects are not binding on the board of county commissioners. The board of county commissioners shall hold at least one public hearing on the plan. Notice of the time and place of the hearing must be provided in the manner set forth in subsection 6. The plan must be approved by the board of county commissioners at a public hearing. Subject to the provisions of subsection 9, on or before the date on which a plan expires, the board of county commissioners shall determine whether a necessity exists for the continued imposition of the tax. If the board determines that such a necessity does not exist, the board shall repeal the ordinance that enacted the tax. If the board of county commissioners determines that the tax must be continued for a purpose set forth in NRS 377B.160, the board shall adopt, in the manner prescribed in this subsection, a new plan for the expenditure of the proceeds of the tax for such a purpose.
8. If the plan approved pursuant to subsection 7 by the board of county commissioners of a county whose population is 100,000 or less includes the expenditure of the proceeds of a tax imposed pursuant to this chapter for a purpose set forth in paragraph (f) or (g) of subsection 3 of NRS 377B.160, the board must review the plan at least once every 4 years.
9. No ordinance imposing a tax which is enacted pursuant to this chapter may be repealed or amended or otherwise directly or indirectly modified in such a manner as to impair any outstanding bonds or other obligations which are payable from or secured by a pledge of a tax enacted pursuant to this chapter until those bonds or other obligations have been discharged in full.
