§ 342. County or part-county health districts; withdrawal of a city.
1. The governing authorities of any city which has consented to be
included in a county or part-county health district, may, at any time
after three years shall have elapsed since such city has been included
in such health district, by resolution adopted by said authorities,
provide for the withdrawal of such city from the county or part-county
health district.

2. Before such action for the withdrawal of a city from a county or
part-county health district is taken an opportunity shall be given for a
public hearing before such governing authorities. Public notice shall be
given and the board of health of the county or part-county health
district shall be notified in writing, at least thirty days in advance,
of the time and place of such hearing.

3. The withdrawal of a city from a county or part-county health
district, shall become effective at a time to be stated in the
resolution adopted by the governing authorities of the city pursuant to
the provisions of this section, which said time shall be not less than
thirty days from the date of the adoption of said resolution. Upon the
date when such resolution shall become effective, the local health
district of such city shall be reinstated and it shall have all the
powers of a local health district as though such city had not been
included in the county or part-county health district pursuant to the
provisions of this article.
