§ 100. Board of supervisors. 1. A county adopting an alternative form
of county government shall continue to have a board of supervisors. The
supervisors of the several cities and towns in the county, when lawfully
convened, shall constitute the board of supervisors.

2. If the petition or resolution for the adoption of an alternative
form of county government or for the modification or change of an
alternative form previously adopted shall so provide and the adoption,
modification or change shall be approved by the voters as herein
provided, the members of the common council or other legislative
governing body of each city within the county shall serve as the members
of the county board of supervisors representing such city and no
separate city supervisors shall be elected. In such case each city shall
continue to have the number of votes on the board of supervisors which
it would have had if this option had not been exercised and the votes of
each city shall be divided equally among the members representing such
city.
