[HISTORY: Adopted by the Town of Windsor Locks 3-29-1960 (Ch. IX, § 1,
of the Town Compilation). Amendments noted where applicable.]
As used in this chapter, the following words are defined, in
order that the regulations and references may be cleared and major
components of the zoning problem understood:
Any contrivance now known or hereafter invented, used or
designed for navigation of or flight in the air.
The Bradley Field Airport.
Any structure, tree or use of land which interferes with
communication between an airport and aircraft approaching or leaving
the same or which obstructs the aerial approaches of an airport or
which is otherwise hazardous to its use for landing or taking off
of aircraft.
These imaginary surfaces are established by reference to
the airport, as described under the title of, and consist of, the
approach surfaces, horizontal surface, conical surface and transitional
surfaces.
A point selected and marked at the approximate center of
the airport landing area.
Distance of zone floors or aerial contours above mean sea
level.
The ground lying under the approach surface.
An inclined plane located directly above the approach area.
The dimensions of the approach area are measured horizontally. The
approach area of Runway 1 has a length of 10,000 feet beginning 200
feet outward from the end of the runway and extending outward; the
approach area of Runway 19 has a length of 10,000 feet beginning 200
feet outward from the end of the runway and extending outward; the
approach area of Runway 6 has a length of 10,000 feet beginning 200
feet outward from the end of the runway and extending outward; the
approach area of Runway 24 has a length of 10,000 feet beginning 200
feet outward from the end of the runway and extending outward; the
approach area of Runway 15 has a length of 10,000 feet beginning 200
feet outward from the end of the runway and extending outward; and
the approach area of Runway 33 has a length of 10,000 feet beginning
200 feet outward from the end of the runway and extending outward.
In addition, the approach area of all runways which may be used for
instrument operation shall extend outward an additional 40,000 feet.
The approach area is symmetrically located with respect to the extended
runway center line, and for an instrument runway has a total width
of 1,000 feet at the end adjacent to the runway. The approach area
flares uniformly to a width of 4,000 feet at the end of the ten-thousand-foot
section and to a total width of 16,000 feet at the end of the additional
forty-thousand-foot section for all the runways not intended for instrument
operation; the approach area has a total width at the end adjacent
to the runway of 500 feet and the width of the approach end is 2,500
feet. For an instrument runway, the slope of the approach surface
along the runway center line extended is 50:1 for the inner ten-thousand-foot
section and 40:1 for the outer forty-thousand-foot section. For the
other runways, the slope is 40:1 for the inner ten-thousand-foot section
and 20:1 for the outer seven-thousand-foot section.
All the air space delineated horizontally by the boundaries
of the Approach Zone District, and in effect complies with and is
synonymous to the approach surface described above.
All that area on the ground lying under the approach zone,
and in effect complies with and is synonymous to the approach area
described under approach surfaces as the ground lying underneath it.
The conical surface extends upward and outward from the periphery
of the horizontal surface with a slope of 20:1 measured in a vertical
plane passing through the airport reference point. Measuring radially
outward, from the periphery of the horizontal surface, the conical
surface extends for a horizontal distance of 7,000 feet.
Distance above mean sea level of points on the earth's
surface, trees and existing or proposed structures.
The elevation of the highest point of the usable landing
area.
A plane, circular in shape, with its height 150 feet above
the established airport elevation and having a radius from the airport
reference point of 13,000 feet.
The area of the airport used for landing, take-off or taxiing
of aircraft.
Any structure, tree, or use of land or building which does
not conform to a regulation prescribed in this chapter or an amendment
thereto.
Objects which project above the landing area or any of the
airport referenced imaginary surfaces, described or defined under
that title and its extensions, shall be considered obstructions to
air navigation. Objects exceeding the limiting heights above ground,
described under that title in the chapter, shall be considered obstructions
to air navigation unless found not to be objectionable after special
aeronautical study.
Any individual, firm, copartnership, corporation, company,
association, joint-stock association or body politic, and including
any trustee, receiver, committee, assignee or other similar representative
thereof.
Any object or thing constructed, erected, placed or installed
above the surface of the ground, including, but without limitation,
buildings, fences, derricks, hay stacks, poles, wires, towers, smoke
stacks, etc.
Inclined planes with a slope of 7:1 measured upward and outward
to a vertical plane at right angles to the center line of the runway.
The transitional surfaces, symmetrically located on either side of
the runway, extend upward and outward from a line on either side of
the runway which is parallel to and level with the runway center line.
These parallel lines are at a horizontal distance from the runway
center line equal to 1/2 the minimum width of the approach area, or
250 feet or 500 feet, noninstrument or instrument runway, respectively.
Transitional surfaces extend from the edges of all approach surfaces
upward and outward to the intersection with the horizontal surface
or the conical surface. The approach surfaces for an instrument runway
projecting through and beyond the limits of the conical surface have
a 7:1 transitional surface extending a distance of 5,000 feet measured
horizontally from the edge of the approach surfaces and at right angles
to the runway center line.
All the air space fixed by the transitional surfaces previously
described and defined, lying above the floor of the surfaces.
All that area on the ground under the transitional surfaces
and transition zones.
Any object of natural growth.
All the air space horizontally within the limits for the
Turning Zone District and lying above the floor of the horizontal
surface and conical surface that together extend 20,000 feet out from
the airport reference point in the form of a circle.
All the area on the ground under the turning zone.
Coincides with the height limitations applying to the district
below it.
Three-dimensional, being the air space usable by aircraft.
A.
To carry out the purposes of this chapter, as approved on March 29,
1960, by Town Meeting, three types of airport zoning districts are
hereby established for Bradley Field Airport for all that land area
within a circle whose radius is 20,000 feet from the airport reference
point, the latitude of which is 41° 56' and the longitude is 72°
41' and for all that land area in the instrument runway, designated
No. 6-24 Approach Zone District extending 10 statute miles in either
direction along the center of said runway from the airport reference
point. The names of the districts are:
B.
There shall be six Approach Zone Districts, 12 Transition Zone Districts
and one Turning Zone District as shown on the Airport Zoning District
Map.
C.
Runway No. 6-24 shall be the instrument runway and Runway No. 1-19
and No. 15-33 shall be the noninstrument runways.
D.
The established airport elevation is 173 feet above sea level.
E.
The airport reference point is located 41° 56' latitude and 72°
41' longitude.
F.
The elevation of the horizontal surface is 323 feet.
The boundaries of each district are hereby established as shown
on a map entitled "Airport Approach Plan for Bradley Field Airport,"
which is attached hereto and is hereby made part of these airport
zoning regulations as though written herein. Copies of said map shall
be filed in the land record offices of the Town Clerk of Windsor Locks
and in the office of the Connecticut Department of Aeronautics.
In the Approach Zone Districts, the following height regulations
will prevail. The height of any structure or tree within the inner
or outer Approach Zone Districts shall not exceed the limitations
of slope defined under approach surface, so as to rise above it, or
exceed the height of the horizontal surface or conical surface of
the turning zone, if the approach surfaces should intersect them.
The height of any tree or structure within a Transition Zone
District shall not rise above the inclined plane of slope 7:1, i.e.,
one foot vertical rise for each seven feet of horizontal measure,
from the approach surfaces, until that plane or surface intersects
the horizontal or conical surfaces of the turning zone, or extending
beyond its limits are the bounds of 5,000 feet along the instrument
runway Approach Zone District, measured horizontally from the edge
and at right angles to the runway center line.
The height of any tree or structure within a Turning Zone District
shall not exceed the limiting heights fixed for the horizontal surface
or the conical surface, i.e., 150 feet above the established airport
elevation or 323 feet above sea level for the horizontal surface,
the conical surface extending from the edge of it, starting at 323
feet and rising one foot vertically in each 20 feet it extends horizontally
for 5,000 feet, with it terminating at a vertical height of 573 feet
above sea level.
In addition to the requirements of objects not extending above
the airport referenced imaginary surfaces, they shall also be considered
obstructions to air navigation and not permitted within the zoned
regions about the airport if they extend 500 feet above the ground,
or fall in the following categories:
A.
Objects more than 150 feet above the ground or more than 150 feet
above the established airport elevation, whichever gives the higher
elevation of the object, within three statute miles of the reference
points of the airport, and increasing in height in the proportion
of 100 feet for each additional mile of distance from the airport
but not to exceed a maximum of 500 feet above ground.
B.
Objects in the instrument Approach Zone Districts whose elevation
would increase the final approach minimum flight. This limitation
extends for a distance of 10 statute miles along the final approach
course outward from the radio facility.
Where districts overlap, the height permitted shall be that
of the district having the most restrictive height regulation.
Any permit that is approved as an exception or variance by the
Connecticut Department of Aeronautics shall be so approved, only on
condition that the owner of the structure or tree mentioned in the
application shall, at its own expense, install, operate and maintain
thereon such markers and lights as may be necessary to indicate to
flyers the presence of an airport hazard.
No permit for the use of land or buildings or for the construction,
extension or alteration of buildings or other structures that fall
within any airport zoning district shall be issued by the Building
Inspector of the Town of Windsor Locks until the application has been
approved as to airport zoning regulations by the Building Inspector
of the Town of Windsor Locks under his authority as administrative
officer, conferred by said ordinance passed March 29, 1960.
A.
The height regulations of this chapter shall be supplementary to
and in addition to the height regulations of the present general Zoning
Ordinance of the Town of Windsor Locks approved July 31, 1953, as
amended.
B.
Where the height regulations of this chapter bear a lower height
limit than the height regulations of the general Zoning Ordinance,
the height regulations of this chapter shall apply to structures and
trees.
C.
In the case of conflict between the requirements of this chapter
and any other regulations applicable to the same area of the airport
zoning district, the more restrictive regulation shall govern.
The rule set forth in Section 11.1 of the ordinance approved
July 31, 1953, as amended, shall apply to this chapter and its several
regulations.
Upon passage of this chapter by Town Meeting as evidence of
the authenticity of the Airport Approach Plan, the plan and all amendments
thereto shall be signed by and attested by the Town Clerk, Clerk of
said meeting.
