California Code, Government Code - GOV § 53338

(a) The hearing may be continued from time to time, but shall be completed within 30 days, except that if the legislative body finds that the complexity of the proposed changes or the need for public participation requires additional time, the hearing may be continued from time to time for a period not to exceed six months. At the conclusion of the hearing the legislative body may abandon the proceedings or may, after passing upon all protests, submit the question of levying a new special tax or of changing the rate or method of apportionment of an existing special tax or of changing the types of facilities and services to be financed by the district, or any combination, to the qualified electors of the district as specified in Article 2 (commencing with Section 53318).

(b) After the canvass of any election conducted pursuant to this section, the legislative body shall adopt a resolution of change determining that the proposed levy of a new special tax or of changes in the types of facilities and services to be financed by the district, or any combination, are lawfully authorized, if two-thirds of the votes cast on the proposition are in favor of the proposed levy or changes.

(c) Upon adoption of a resolution of change, the clerk of the legislative body shall record notice of the changes pursuant to Section 3117.5 of the Streets and Highways Code.
