The ordinance shall be subject to voter approval by the electors in those portions of the district to which the tax applies and shall be consistent with Section 102350.

(1) The incorporated area of each city and of contiguous cities within the district shall be either wholly included within that portion or wholly excluded from that portion. For purposes of this paragraph, “contiguous cities” means two or more cities with shared borders.

(2) The entire unincorporated area of the district shall either be wholly included within that portion or wholly excluded from that portion.

(3) The revenues derived from the tax shall be spent within, or for the benefit of, the portion of the area of the district to which the tax applies, and shall be spent only on allowable transportation and transit infrastructure and services.
