Wat. Code, § 35535

No zone shall be established or varying rates of assessments fixed under Section 35534 unless the board by resolution declares that it intends to do so and that a public hearing will be held thereon at a specified day and place where all interested persons may appear and be heard. This resolution shall be published in the district pursuant to Section 6066 of the Government Code in a newspaper of general circulation published in Kern County, with the first publication to be at least 14 days prior to the time fixed for hearing, and a copy of said resolution shall be mailed, postage prepaid, to each holder of title to land within the district at his address as shown upon the last equalized assessment roll of Kern County. Any error, omission or mistake in such mailing, or any failure of any person to receive such copy, shall not invalidate the proceedings pursuant to this chapter. The hearing may be adjourned from time to time at the discretion of the board and at its conclusion the board shall by resolution determine the zones of benefit established, if any, the share of benefits received by each zone arising from the district’s operations, expressed as a percent, the criteria for establishing each such zone and the percentage expressed, together with a map in such detail to delineate the geographical area of such zone. The zones and the percentages may be amended from time to time or abolished in the same manner required for original adoption.
