N.Y. County Law § 261: Administration of the county district

§ 261. Administration of the county district. When a county district

shall have been established, the board of supervisors shall appoint,

designate or establish an officer, board or body as the administrative

head or body of the district. All matters relating to the membership of

such administrative head or body, including but not limited to, numbers,

method of selection, tenure, qualifications and compensation, shall be

determined by the board of supervisors. A member of the board of

supervisors or any other county officer or official may be appointed as

administrative head or as a member of the administrative body provided

that he shall receive no additional salary or compensation for such

services. The administrative head or body of one or more county

districts shall be considered to be the administrative head or body of

an administrative unit of county government. The title of such

administrative head or body, if such functions are not conferred on an

existing officer or body, and the name of such administrative unit, if

the county district is made a separate administrative unit of county

government, shall be prescribed by the board of supervisors, and such

officer or body shall have all the powers generally conferred on heads

of administrative units by this chapter, not inconsistent with the

provisions of this article, and shall be subject to all of the duties

imposed upon such heads by this chapter, not inconsistent with the

provisions of this article.
