The rate of tax authorized by this section, when combined with the rate of tax authorized by voter approval of Measure R pursuant to Section 130350.5 during any period when that tax is in effect, and upon the expiration of that tax, shall not exceed 1 percent.

(b) The ordinance imposing the tax shall contain all of the following:

(1) An expenditure plan that lists the transportation projects and programs to be funded from net revenues from the tax. The expenditure plan shall appear in the ordinance as an exhibit. The expenditure plan shall include all of the following:

(A) The most recent cost estimates for each project and program identified in the expenditure plan.

(B) The identification of the accelerated cost, if applicable, for each project and program in the expenditure plan.

(C) The approximate schedule during which the MTA anticipates funds will be available for each project and program.

(D) The expected completion dates for each project and program within a three-year range.

(2) Provisions conforming to the Transactions and Use Tax Law (Part 1.6 (commencing with Section 7251) of Division 2 of the Revenue and Taxation Code), except as otherwise provided in subdivision (f).

(3) A provision limiting the MTA’s costs of administering the ordinance and the net revenues from the tax to 1.5 percent of the total tax revenues.

(4) A requirement that the net revenues from the tax, defined to mean the total tax revenues less any refunds, costs of administration by the State Board of Equalization, and the MTA’s administration costs, shall be used by the MTA to fund transportation projects and programs identified in the expenditure plan.

(5) The rate of the tax.

(c) The MTA shall do both of the following:

(1) Develop a transparent process to determine the most recent costs estimates for each project and program identified in the expenditure plan.

(2) At least 30 days before submitting the ordinance described in subdivision (b) to the voters, post the expenditure plan on its Internet Web site in a prominent manner.

(d) The ordinance shall be adopted by the MTA board, which shall also adopt a resolution that submits the ordinance to the voters.

(e) The ordinance shall become operative pursuant to Section 130352 if approved by two-thirds of the voters voting on the measure, pursuant to subdivision (d) of Section 2 of Article XIII C of the California Constitution.

(f) (1) If the voters approve the ordinance authorized by this section, the expenditure plan included as an exhibit to the ordinance pursuant to paragraph (1) of subdivision (b) shall also be included in the revised and updated Long Range Transportation Plan within one year of the date the ordinance takes effect. The revised and updated Long Range Transportation Plan shall also include capital projects and capital programs that are adopted by each subregion that are submitted to the MTA for inclusion in the revised and updated Long Range Transportation Plan, if the cost and schedule details are provided by the subregions, in a manner consistent with the requirements of the plan. Inclusion of a capital project or a capital program in the Long Range Transportation Plan is not a commitment or guarantee that the project or program shall receive any future funding.

(2) For purposes of this subdivision, “subregion” shall have the same meaning as defined in the Long Range Transportation Plan.

(g) The MTA may incur bonded indebtedness payable from the net revenues of the tax pursuant to the bond issuance provisions of Chapter 5 (commencing with Section 130500) and any successor act.

(h) The tax authorized by this section shall be imposed pursuant to the Transactions and Use Tax Law (Part 1.6 (commencing with Section 7251) of Division 2 of the Revenue and Taxation Code), notwithstanding the combined rate limitation in Section 7251.1 of the Revenue and Taxation Code.
