Variances
Section 16.180 Variances
a) General.
Any person wishing to erect or increase the height of any structure or permit
any vegetation or use of his/her property not in accordance with this Part must
obtain a variance from the Division.
b) Marking
and Lighting. Any variance granted by the Division may be so conditioned as to
require the owner of the structure or vegetation to permit, at the expense of
the owner, the installation, operation and maintenance of markers and lights as
may be required to indicate to pilots the presence of the structure or
vegetation.
c) In
making a determination to allow a variance, the Division will consider, but is
not limited to considering:
1) the
proximity of the hazard to the normal flight path or traffic patterns at the
airport;
2) the
proximity of other non-conforming uses, structures or vegetation that would
impair the use of the airport;
3) the
height of the object;
4) the
volume of air traffic at the airport;
5) the
type of aircraft using the airport;
6) the
type of navigational aids used at the airport;
7) the
length and width of existing runways; and
8) the
plans for future expansion of the airport.
Variances
would be granted
when it is found that
a literal application or enforcement of
this Part
will
result in practical difficulty or unnecessary hardship and the relief
granted
is
not contrary to the public interest but
would
do
substantial
justice and
will
be in accordance with the spirit of the Act
.
(Section 24 of the Act)
d) A
decision to grant or deny a variance will be made by the Division within 30
calendar days after receipt of the notice (see Section 16.160) or within 30
calendar days after receipt of supplemental information (see Section
16.160(c)(2)(C)). The person or sponsor may appeal any decision made by the
Division (see Section 16.190).
