Whenever a vacancy exists, by resignation, removal or otherwise,
in the office of a Director of any City department, the Mayor may
temporarily fill such vacancy in cases not specifically provided for
in the Charter or ordinances by appointing an Acting Director from
among the existing officers and employees of the City, who shall perform
all the duties and functions of such department head, until the office
shall be filled permanently. Any such appointment of an Acting Director
shall terminate not later than 90 days after the date of the appointment,
unless the Council shall, by resolution, authorize one or more extensions
thereof.
Whenever any administrative officer or the head of any administrative
department or division thereof is, by reason of absence or disability,
unable to perform his or her official duties, one or more officers
or employees under his or her supervision whom he or she has designated
may perform the ministerial duties of such office during such time
as the absence or disability of the officer may continue. It shall
be the duty of the head of each department and division to designate
one or more such persons. When any person so designated to perform
the duties of an officer during his or her absence or disability is
required to sign any official document pertaining to such office,
it shall be signed in the name of such officer and by the subordinate
as designee.
