A director must be appointed for each municipal and county or regional emergency management agency. A director of an emergency management agency may not be at the same time an executive officer or member of the executive body of a municipality or interjurisdictional or county or regional agency of the State or a county commissioner. Notwithstanding this section or any other law, a town manager or administrative assistant may also be appointed to serve as the director of an emergency management agency. A director may be removed by the appointing authority for cause. [2003, c. 510, Pt. A, §35 (RPR).]
