The O-A Overlay Airport District prevents the
establishment of flight or safety hazards within the vicinity of the
Rochester - Monroe County Airport. The district recognizes the approach-departure
corridors where development might endanger the lives and property
of residents of the area, airport operations or aircraft. The Overlay
Airport District shall not be independently mapped upon the Zoning
Map but shall be overlaid upon existing zoning districts. When so
mapped, the Overlay Airport District shall provide regulations and
review procedures in addition to those required in the underlying
district.
The Overlay Airport District shall consist of
two sections, an inner section and an outer section.
A. Inner district. The O-A Overlay Airport District (Inner)
shall be established over the area within one mile from the boundary
line of the Rochester - Monroe County Airport and within the approach-departure
corridors of instrument-equipped runways at the airport over an area
not to exceed three miles from the end of the runway and one mile
in width. The boundaries of the Overlay Airport District (Inner) may
be changed from time to time as necessary to reflect the current configuration
and utilization of the airport and its facilities. The Manager of
Zoning shall request annually from the Monroe County Department of
Planning and Development information concerning any changes or projected
changes involving instrument runway layout, airport boundaries or
general airport operations or use.
[Amended 6-16-2009 by Ord. No. 2009-179; 6-20-2017 by Ord. No. 2017-170]
B. Outer district. The O-A Overlay Airport District (Outer)
shall be established over the remainder of the area within the corporate
limits of the City of Rochester not covered by the Overlay Airport
District (Inner).
Referral required prior to City action. The
following applications shall require referral to the Monroe County
Department of Planning and Development in accordance with the provisions
of § C5-4A of the Monroe County Charter:
A. Inner district. Any application for any of the following
actions within the O-A District (Inner):
(2) Changes in land use by amendment of the provisions
of this chapter, special permit or variance.
(3) Other significant changes in land use.
(4) Development of vacant land.
(5) Any land use which might create a flight or safety
hazard by reason of electronic interference, impairment of visibility,
glare, flammability, radiation, height or any other feature.
B. Outer district. Any application for any of the following
actions within the Overlay Airport District (Outer):
(1) Any land use which might create a flight or safety
hazard by reason of electronic interference, impairment of visibility,
glare, flammability, radiation, height or any other feature.
(2) Any application for a special permit for height or
a variance in accordance with the provisions of this article.
Within the Overlay Airport District, both inner
and outer sections, no building, structure or use that is not specifically
limited to a lower maximum height by the zoning district in which
it is to be located shall be permitted to extend above an imaginary
plane the height of which is determined as follows:
A. Vertical height. Vertical height of the imaginary
plane shall be measured from an elevation of 559 feet above mean sea
level, which is the elevation of Rochester - Monroe County Airport
Runway 10-28.
B. Horizontal distance. Horizontal distance shall be
measured from the airport location point (ALP) defined by the United
States Department of Commerce, National Oceanic and Atmospheric Administration,
as being located within the Rochester - Monroe County Airport at a
latitude of 43º 07' 11.2" and a longitude of 77º 40' 18.2".
C. Location-determined height and distance.
(1) For all locations less than 8,000 feet from the ALP,
the height of the imaginary plane shall be 40 feet.
(2) For all locations between 8,000 and 10,000 feet from
the ALP, the height of the imaginary plane shall begin at 50 feet
and shall increase one foot in height for every 40 feet of horizontal
distance to a maximum height of 100 feet at a distance of 10,000 feet.
(3) For all locations between 10,000 and 25,000 feet from
the ALP, the height of the imaginary plane shall begin at 100 feet
and shall increase one foot in height for every 50 feet of horizontal
distance to a maximum height of 400 feet at a distance of 25,000 feet.
(4) For all locations beyond 25,000 feet from the ALP, the height of the imaginary plane shall be 400 feet. Any building, structure or use may extend above this plane subject to the issuance of a special permit as provided in §
120-192.
D. Table of dimensions. The following table illustrates
the height of the imaginary plane, measured from 559 feet above mean
sea level, defined in this section:

Any tree, shrub or other object of natural growth
located within the Overlay Airport District that exceeds the maximum
permitted heights defined in this article or otherwise impairs visibility
may be declared to be a flight hazard and may be required to be removed,
trimmed or otherwise altered at the owner's expense.
No building, structure or use shall be established,
created or constructed which creates or is expected to create a flight
or safety hazard. No certificate of zoning compliance shall be issued
for such a building, structure or use.
