Article 1. Administration of California Health And Safety Code >> Division 26. >> Part 3. >> Chapter 2. >> Article 1.

Except as provided in Section 40100.5, a county board of supervisors shall be ex officio the county district board of the county.

(a) The membership of the governing board of each county district shall include (1) one or more members who are mayors, city council members, or both, and (2) one or more members who are county supervisors.
  (b) The number of those members and their composition shall be determined jointly by the county and the cities within the district, and shall be approved by the county, and by a majority of the cities that contain a majority of the population in the incorporated area of the district.
  (c) The governing board shall reflect, to the extent feasible and practicable, the geographic diversity of the district and the variation of population between the cities in the district.
  (d) (1) The members of the governing board who are mayors or city council members shall be selected by the city selection committee. When selecting a member of the governing board, the city selection committee may also select a mayor or another city council member as an alternate to serve and vote in place of the member who is absent or disqualified from participating.
  (2) In districts where the county and the cities have agreed that each city shall be represented on the governing board, each city shall select its own representative to the governing board. When selecting a member of the governing board, each city may also select its mayor or another city council member as an alternate to serve and vote in place of the member who is absent or is disqualified from participating.
  (3) The members of the governing board who are county supervisors shall be selected by the county.
  (e) This section does not apply to any district in which the population of the incorporated area of the county is 35 percent or less of the total county population, as determined by the district on June 30, 1994, or to a county district having a population of more than 2,500,000 as of June 30, 1990.
  (f) If a district fails to comply with subdivisions (a) and (b), the membership of the governing board shall be determined as follows:
  (1) In districts in which the population in the incorporated areas represents between 36 and 50 percent of the total county population, one-third of the members of the governing board shall be mayors or city council members, and two-thirds shall be county supervisors.
  (2) In districts in which the population in the incorporated areas represents more than 50 percent of the total county population, one-half of the members of the governing board shall be mayors or city council members, and one-half shall be county supervisors.
  (3) The number of those members shall be determined as provided in subdivision (b), and the members shall be selected pursuant to subdivision (d).
  (4) For purposes of paragraphs (1) and (2), if any number that is not a whole number results from the application of the term "one-third," "one-half," or "two-thirds," the number of county supervisors shall be increased to the nearest integer, and the number of mayors or city council members decreased to the nearest integer.

(a) Section 40100.5 shall not apply to a county district if each city in the county consents, by the adoption of an ordinance or resolution, to the exclusion of the county district from the requirements of Section 40100.5.
  (b) Within 60 days from the date of the adoption of an ordinance or resolution by all cities in the county to exclude the county district from the requirements of Section 40100.5, if requested by a majority of the cities in the county, the county district shall establish an advisory committee consisting of a mayor, or a city council member, from each city in the county. The members shall be selected by the city selection committee.
  (c) Subdivision (a) shall become inapplicable, and Section 40100.5 shall apply, if, at any time after the condition prescribed in subdivision (a) has been met, a majority of the cities which contain a majority of the population in the incorporated areas of the county, as established by the most recent census data, have adopted resolutions requesting the application of Section 40100.5.

(a) (1) The board of supervisors of a county in which a county district is functioning may appropriate funds to the county district, which funds shall be deposited in the treasury of the county district.
  (2) All such appropriations are legal charges against the county.
  (b) A county district may contract, by a memorandum of understanding, joint powers agreement, or other agreement, with the county in which the county district is functioning, to provide facilities and administrative, legal, health coverage, risk management, clerical, and other support services, including, but not limited to, those facilities and services that the county provided to the county district prior to July 1, 1994.

A county district which is included entirely within another district created by special law, or pursuant to Chapter 5 (commencing with Section 40300), shall cease to function and exercise its powers upon the date the other district commences to function and exercise its powers.

When a county district ceases to function and exercise its powers because it is included entirely within a regional district created pursuant to Chapter 5 (commencing with Section 40300), the regional district shall succeed to all the funds, property, and obligations of the county district. Where the county district is included within two or more such regional districts, the funds, property, and obligations of the county district shall be apportioned to the regional districts as agreed upon by the regional districts and county district.

Notwithstanding any other provision of law, a county may delegate air pollution rulemaking and enforcement duties to a duly created joint powers authority established for air pollution control purposes of which the county is a member.
