California Code, Government Code - GOV § 61141

(a) At the hearing, the board of directors shall hear and consider any protests to the formation of the zone. If, at the conclusion of the hearing, the board of directors determines either that more than 50 percent of the total number of voters residing within the proposed zone have filed written objections to the formation, or that property owners who own more than 50 percent of the assessed value of all taxable property in the proposed zone have filed written objections to the formation, then the board of directors shall terminate the proceedings. If the board of directors determines that the written objections have been filed by 50 percent or less of those voters or property owners who own 50 percent or less than the assessed value of all taxable property, then the board of directors may proceed to form the zone.

(b) If the resolution or petition proposes that the zone use special taxes, benefit assessments, fees, standby charges, bonds, or notes to finance its purposes, the board of directors shall proceed according to law. If the voters or property owners do not approve those funding methods, the zone shall not be formed.
