(a)This section applies to:
(1)an existing public use airport; and
(2)a public use heliport.
(b)If any of the obstruction standards set forth in this subsection are
exceeded, the proposed structure is presumed to have a substantial
adverse effect upon the safe and efficient use of the navigable airspace
and would be a hazard to air navigation if constructed. Except as
provided in section 9 of this chapter, the department shall not issue a
permit for any proposed structure that would exceed any of the
following obstruction standards:
(1)A height that is five hundred (500) feet above ground level at
the site of the object anywhere in the state.
(2)A height that is two hundred (200) feet above ground level or
above the established airport elevation, whichever is higher,
within three (3)

(a) This section applies to:
(1) an existing public use airport; and
(2) a public use heliport.
(b) If any of the obstruction standards set forth in this subsection are
exceeded, the proposed structure is presumed to have a substantial
adverse effect upon the safe and efficient use of the navigable airspace
and would be a hazard to air navigation if constructed. Except as
provided in section 9 of this chapter, the department shall not issue a
permit for any proposed structure that would exceed any of the
following obstruction standards:
(1) A height that is five hundred (500) feet above ground level at
the site of the object anywhere in the state.
(2) A height that is two hundred (200) feet above ground level or
above the established airport elevation, whichever is higher,
within three (3) nautical miles of the established reference point
of a public-use airport, excluding heliports, and that height
increases in the proportion of one hundred (100) feet for each
additional nautical mile of distance from the airport up to a
maximum of five hundred (500) feet.
(3) A height within a terminal obstacle clearance area, including
an initial approach segment, a departure area, and a circling
approach area, as defined by federal law and regulations, which
would result in the vertical distance between any point on the
object and an established minimum instrument flight altitude
within that area or segment to be less than the required obstacle
clearance.
(4) A height within an enroute obstacle clearance area, as defined
by federal law and regulations, including turn and termination
areas of a federal airway or approved off-airway route that would
increase the minimum obstacle clearance altitude.
(5) The surface of a takeoff and landing area of a public-use
airport or heliport or any imaginary surface as established under
section 8 of this chapter. However, no part of the takeoff or
landing area itself will be considered to be an obstruction.
(c) Except for traverse ways on or near an airport with an operative
ground traffic control service, furnished by an air traffic control tower
or by the airport management and coordinated with the air traffic
control service, the standards set forth above in subsection (b) apply to
traverse ways used or to be used for the passage of mobile objects only
after the heights of these traverse ways are increased by the following:
(1) Seventeen (17) feet for an interstate highway where
overcrossings are designed for a minimum of seventeen (17) feet
vertical distance.
(2) Fifteen (15) feet for any other public roadway.
(3) Ten (10) feet or the height of the highest mobile object that
would normally traverse the road, whichever is greater, for a
private road.
(4) Twenty-three (23) feet for a railroad.
(5) For a waterway or any other traverse way not covered by
subdivisions (1) through (4), an amount equal to the height of the
highest mobile object that would normally traverse it.
