11/12/2013 16.D.6.
EXECUTIVE SUMMARY
Recommendation to revise the Freedom Park and Gordon River Greenway Park Land
Management Plan to reflect accurate height limitations for structural and natural obstructions.
OBJECTIVE: To revise the Freedom Park and Gordon River Greenway Park Land Management Plan to
reflect accurate height limitations for structural and natural obstructions.
CONSIDERATIONS: The Freedom Park and Gordon River Greenway Park Land Management Plan,
page 9, end of 2 paragraph, provides the following information about height restrictions for natural and
man-made structures within the Airport Overlay Zone:
There is an existing Airport Overlay Zone that limits the height of obstructions on parts
of the Gordon River Greenway Park to 150 feet; however, this provides no potential
conflict regarding the uses or management of the project site.
This information was taken from the Land Development Code, Section 4.02.06, E. and G.
The Naples Airport Authority advises, however, that the height limitations are more nuanced and that a
F.A.R. Part 77 Surfaces Map provides more comprehensive height restriction information and shows
heights for a conical plane that rises from each runway with obstruction surfaces that are lower than 150
feet in some locations.
The text should read:
There is an existing Airport Overlay Zone that limits the height of obstructions on parts of the
Gordon River Greenway Park as described in Collier County, FL Land Development Code,
Section 4.02.06- Standards for Development in Airport Zones and as attached as Exhibit P to
the Manapement Plan, which is consistent with State and Federal laws This provides no
potential conflict regarding the uses of the project site, but may require removal or reduction of
trees deemed by the Naples Airnort Authority as obstructions
Two exhibits will also be added to the Plan:
• Exhibit O — LDC Section 4.02.06 — Standards for Development in Airport Zones
• Exhibit P — Federal Aviation Regulations (FAR) Part 77 Imaginary Surfaces Map for Naples
Airport
FISCAL EWPACT: The obstruction surfaces may require that some native pines are removed or topped.
The number of native pines affected, though expected to be minimal, along with the cost associated with
removing them is unknown at present. However, the Naples Airport Authority is working with the
County to provide funding for exotic vegetation removals tied to an Avigation Easement over parts of the
Gordon River Greenway. This funding will be used for any necessary removals of native pines.
GROWTH MANAGEMENT IMPACT: There is no growth management impact resulting from this
action.
LEGAL CONSIDERATIONS: This item is approved as to form and legality and requires a majority
vote for Board action.

4.02.06 Standards for Development in Airport Zones
A. There are hereby created and established certain surfaces which include all of the land lying
beneath the approach, transitional, primary, horizontal, and conical surfaces as they apply to
a particular airport. Such zones are shown on the Naples Municipal, Marco Island
Executive, Everglades City, and Immokalee Regional Airport zoning maps and declared to
be made a part of this LDC. An area located in more than one of the described zones is
considered to be only in the zone with the most restrictive height limitation.
B. Primary surface. An area longitudinally aligned along the runway centerline, extending 200
feet beyond each end of the runway with the width so specified for each runway for the most
precise approach existing or planned for either end of the runway.
C. Primary surface height. No structure or obstruction will be permitted within the primary
surface area that is not part of the landing and takeoff area and is of greater height than the
nearest point on the runway centerline with the exception of FAA approved navigation aids.
D. The width of each primary surface is as follows:

Horizontal zone height. No structure or obstruction will be permitted in the horizontal zone
that has a height greater than 150 feet above the airport height.
G. Conical zone. The conical zone is the area extending outward and upward from the
periphery of the horizontal zone for a distance of 4,000 feet. Height limitations for structures
in the conical zone are 150 feet above airport height at the inner boundary with permitted
height increasing one (1) foot vertically for every twenty (20) feet of horizontal distance
measured outward from the inner boundary to a height of 350 feet above airport height at
the outer boundary.
H. Approach zone. The approach zone is an area longitudinally centered on the extended
runway centerline and extending outward and upward from each end of the primary surface.
An approach zone is designated for the end of each runway based upon the type of
approach available or planned for that runway end.
1 Approach zone width. The inner edge of the approach zone is the same width as the
primary surface. The outer width of the approach zone is prescribed for the most
precise approach existing or planned for that runway end expanding uniformly to the
following widths:

4. Precision instrument runway(s). One (1) foot vertically for every fifty (50) feet
horizontally for the first 10,000 feet, increasing to one (1) foot vertically for every forty
(40) feet horizontally for additional 40,000 feet.
5. Non - precision instrument runways. One (1) foot vertically for every thirty -four (34) feet
horizontally.
6. Visual runways. One (1) foot vertically for every twenty (20) feet horizontally.
Transitional zones. The area extending outward from the sides of the primary surface and
approach zones connecting them to the horizontal zone or for a horizontal distance of 5,000
feet from the side of the part of the precision approach zone that extends beyond the conical
zone. Height limits within the transitional zone are the same as the primary surface or
approach zone at the boundary line where it adjoins and increases at a rate of one (1) foot
vertically for every seven (7) feet horizontally, with the horizontal distance measured at right
angles to the runway centerline and extended centerline until the height matches the height
of the horizontal zone or for a horizontal distance of 5,000 feet from the side of the part of the
precision approach zone that extends beyond the conical zone.
Heliport primary zones. The area of the primary zone coincides in size and shape with the
designated take -off and landing area of a heliport. This surface is a horizontal plane at the
established heliport elevation.
1 Heliport approach zone. The approach zone begins at each end of the heliport
primary zone with the same width as the primary zone, and extends outward and
upward for a horizontal distance of 4,000 feet where its width is 500 feet. The slope of
the approach zone is eight (8) to one (1) (one (1) foot vertically for every eight (8) feet
horizontally.)
2. Heliport transitional zone. These zones extend outward and upward from the lateral
boundaries of the heliport primary zone and from the approach zone at a slope of two
(2) to one (1) (one (1) foot vertically for every two (2) feet horizontally) for a distance
of 250 feet measured horizontally from the centerline of the heliport primary and
approach zone.
K. Other areas. In addition to the height limitations imposed in sections 4.02.06(E) -(H) above, ^
no structure or obstruction will be permitted within Collier County that would cause a

minimum obstruction clearance altitude (MOCA), a minimum descent altitude (MDA),
decision height (DH), or a minimum vectoring altitude (MVA) to be raised nor which would
impose either the establishment of restrictive minimum climb gradients or nonstandard
takeoff minimums.
1 • Except as expressly provided in these APO regulations, no structure or object of
natural growth shall be erected, altered, allowed to grow, or be maintained to a height
which exceeds the height of any zone created in these APO regulations.
2. Except as otherwise provided in these APO regulations, no structure, or object of
natural growth shall be erected, altered, allowed to grow or be maintained, which is or
would be an obstruction to air navigation within Collier County or of a height greater
than any of the following:
a• A height of 500 feet above ground level at the site of the object.
b• A height that is 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 an airport, excluding heliports, with its longest runway more
than 3,200 feet in actual length, and that height increases in the proportion of
100 feet for each additional nautical mile of distance from the airport up to a
maximum of 500 feet.
C. A height within a terminal obstacle clearance area, including an initial approach
segment, a departure area, and a circling approach area, 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. (Refer to FAR 77.21(a)(2)).
L Exemptions. Development of the Marco Shores Golf Course Community that comports with
the location and height requirements of Ordinance No. 81 -6, as amended by Ordinance No.
85 -56 and Ordinance No. 94-41, is exempted from the provisions of section 4.02.06 only to
the following extent:
1 The agreement between Johnson Bay Development Corporation Collier County
Airport Authority and the BCC, dated August 8, 1995.
2. Prior issuance of a Federal Aviation Administration "Determination Of No Hazard To
Air Navigation."
M. Airport land use restrictions. Notwithstanding any other provision of this LDC, no use may
be made of land or water within any zones established by this LDC in such a manner as to
interfere with the operation of an airborne aircraft. The following special requirements shall
apply to each permitted use:
1 All lights or illumination used in conjunction with street, parking, signs, or use of land
or structures shall be arranged and operated in such a manner that it is not
misleading to pilots or dangerous to aircraft operating from a public use airport or in
the vicinity thereof.
2. All flood lights, spot lights, or any type of pulsating, flashing, rotating, or oscillating
light shall be modified or prohibited if determined by the executive director who has
authority over that public airport to be a possible risk to safety of aircraft operation.
3• No operations of any type shall produce smoke, glare, or other visual impairment to
pilots within three (3) miles of any usable runway of a public airport.
4• No operations of any type shall produce electronic interference with navigation signals
n or radio communication between the airport and aircraft, or other air traffic control
facility.

Exhibit O 11/12/2013 16.D.6.
Land within runway clear zones (runway protection zones) shall be prohibited from
use for high density residential use, schools, hospitals, storage of explosives, or Al—N
flammable material, assemblage of large groups of people or any other use that could
produce a major catastrophe as a result of an aircraft crash.
6. Based on the possibility that solid waste management facilities may attract birds, any
solid waste management facility located so that it places the runways and /or
approach and departure pattern of an airport between bird feeding, water, or roosting
areas shall be considered as an incompatible use and is therefore prohibited in and
around the airports in Collier County.
7. Any type of tethered dirigible, balloon, or other type of hovering or floating object the
height of which exceeds the airspace notification limits outlined in section 4.02.06 E.
shall be limited as provided in section 4.02.06 E.
$• No structure of any height, type or material shall be constructed or altered which
could possibly cause interference to any airport surveillance radar system as
determined by the Federal Aviation Administration, or by the executive director who
has jurisdiction over the airport deemed to be effected.
N. Naples Municipal Airport noise zones, land use restrictions, sound level requirements (SLR)
for buildings or structures, and SLR design requirements.
1 The purpose of this section 4.02.06 is to establish standards for land use and for
sound level reduction requirements with respect to exterior noise resulting from the
legal and normal operations at the airports within Collier County. This section
establishes noise zones of differing intensities and land use in the vicinity of the
Naples Municipal airport, as identified in the most recent Naples airport FAA Part
150 Study; establishes permitted land uses in the noise zones; establishes
soundproofing requirements for residential development within the noise zones; and
establishes notification procedures to prospective purchasers of real estate within the
noise zones.
2. In addition to the prior three (3) noise zones, there is hereby created and established
a fourth noise zone D; there are now noise zones A, B, C, and D. Such zones are
shown on the Naples Airport noise zone map(s) which are incorporated and made a
part herein and are described in section 4.02.06 N.3. below. The noise zones
contained herein are based on a projection of future aircraft operations at the Naples
Municipal Airport. The purpose of these noise zones is to define and set forth specific
regulations for all properties within the described areas.
3. Noise zone boundaries.
a. Zone A. That area commencing at the outermost boundary of the airport and
extending outward therefrom to a boundary indicated on the noise zone map as
"B." The outer contour of noise zone A approximates a noise level of seventy-
five(75)Ldn.
Zone B. That area commencing at the boundary indicated on the noise zone
map as the outer boundary of noise zone A and extending outward therefrom
to the boundary indicated on the noise zone map as "C." The outer contour of
noise zone B approximates a noise level of seventy (70) Ldn.
C. Zone C. That area commencing at the boundary indicated on the noise zone
map as the outer boundary of noise zone B and extending outward therefrom
to the boundary indicated on the noise zone map as "D ". The outer contour of
noise zone C approximates a noise level of sixty -five (65) Ldn.
d.

Exhibit O 11/12/2013 16.D.6.
Zone D. This new noise zone commences at the boundary indicated on the
i-� noise zone map as the outer boundary of noise zone C and extending outward
therefrom to the furthermost boundary indicated on the noise zone map. The
outer contour of noise zone D approximates a noise level of sixty (60) Ldn and
is the Naples Airport noise zone (This area is referenced in the 1996 Naples
Airport FAA Part 150 Study).
4. Where boundaries of a described noise zone are shown to extend over a portion, but
not all, of a platted lot or unsubdivided property, the owner or owners of the entire
property will be notified of potential noise impact in accordance with notice procedures
set forth in Chapter 10.
a. Where boundaries of a described noise zone are shown to extend over a
portion, but not all of a platted lot or un- subdivided property, the owner or
owners of the entire property will be notified of potential noise impact in
accordance with notice procedures set forth in Chapter 10.
b. Where boundaries of more than one (1) described noise zone are shown on a
platted lot or unsubdivided property, provisions of the most restricted zone
shall apply.
5. Land use restrictions.
a. Permitted and restricted activities. All land uses shall be permitted in the noise
zone pursuant to the applicable zoning district and as provided in the activities
and /or land use guidance chart made a part hereof. Those activities and land
uses not specifically listed in the land use guidance chart are permitted or
restricted in the noise zones based on their similarity to noise tolerance as
exhibited by the activities and land uses which are listed in the guidance chart.
b. Nonconforming uses. The regulations prescribed by this section shall not be
construed to require the sound conditioning or other changes or alteration of
any preexisting structure not conforming to this part as of the effective date of
this section or to otherwise interfere with the continuance of any such
preexisting nonconforming use. Nothing herein contained shall require any
such change in the construction of or alteration of a structure which has
commenced construction prior to the effective date of this section and which is
diligently pursued.
6. Sound level requirements (SLR) for buildings or structures.
a. The provisions of these APO special regulations shall apply to the construction,
alteration, moving, demolition, repair, and use of any building or structure
within unincorporated Collier County except work located primarily in a public
right -of -way, on public utility towers, poles, and mechanical equipment not
specifically regulated by these APOs. Additions, alterations, repairs, and
changes of use in all buildings and structures shall comply with the
provisions of these APOs.
b. Buildings or structures constructed prior to the initial adoption of this
amended section, to which additions, alteration, or repairs are made to the
exterior walls and ceilings of rooms having one (1) or more exterior walls or
ceilings shall be required to meet the SLR requirements of these APOs.
C. Alterations or repairs which are nonstructural and do not affect the exterior
walls or ceilings of an existing building or structure may be made with the
same materials of which the building or structure is constructed and shall not
be required to meet SLR requirements.

Exhibit O 11/12/2013 16.D.6.
d. Buildings in existence at the time of the initial adoption of these APOs may
have their existing use or occupancy continued if such use or occupancy was
legal at the time of the initial adoption of these APOs provided such continued
use is not dangerous to life. A change in the use of a structure may require
additional sound level reduction.
e• Buildings or structures moved into or within the vicinity of the established
noise zone must comply with applicable provisions of these APOs.
f. The County Manger or his designee may approve any type construction that
complies with the SLR requirements of the activities and /or land use guidance
chart (appendix III of Appendix D). The SLR requirements specified in appendix
III of Appendix D shall be achieved by the use of assemblies having the South
Transmission Class Ratings specified in table 403.2, Minimum Sound
Transmission of Assemblies, of the Southern Building Code Congress
International, Inc., Standard for Sound Control, SSTD 8 -87, incorporated herein
and adopted by reference as appendix IV of appendix D.
9• The SLR requirements of the land use guidance chart at appendix III of
Appendix D may be achieved by any suitable combination of building design,
choice of building materials, and execution of construction details in
accordance with established architectural and acoustical principles. The SLR
requirements shall apply to the exterior walls and ceilings only of all rooms
having one (1) or more exterior walls or ceilings. Regulations to achieve the
SLR requirements specified in appendix III of Appendix D, shall be found in
appendix IV of Appendix D and shall be used by the County Manger or his
designee during the building plan review process.
h• No building or structure for which an SLR 25, SLR 30, or SLR 35 is required
by appendix III of Appendix D may be constructed, altered, moved,
demolished, or repaired unless and until a building permit has been issued.
No such permit shall be issued unless and until the requirements contained in
appendix III of Appendix D are met as indicated by plans and specifications for
the building or structure. Such plans and specifications shall result in a sound
level reduction for the applicable exterior walls and ceilings only of room(s)
having one (1) or more exterior walls or ceilings, at least as great as the SLR
value specified in appendix III of Appendix D for the particular usage involved.
These plans and specifications shall be reviewed during the building plan
review process in accordance with the sound transmission ratings specified in
table 403.2 of appendix IV of Appendix D.

permit. (Furthered by Management Objective 5.)
The Future Land Use designation for Freedom Park is Public Land Use - Recreation (City
of Naples Future Land Use), changed on February 7, 2007. The zoning classification
(City of Naples Zoning) was changed to Transitional Conservation District on March 21,
2007. The Future Land Use designation for the Gordon River Greenway Park and
Conservation Collier Preserve sites is currently Urban Mixed -Use District, Urban
Residential Subdistrict (Collier County future Land Use). A petition to change the
designation to a Public Use District is in process and will be completed by the end of
2012. . Original zoning on the Greenway and Conservation Collier sites included Rural
Agricultural, Conservation, Commercial Intermediate and Residential Multi - family
District -6, with a Special Treatment overlay covering a portion of the project along the
Gordon River. These lands were rezoned to Public Use on July 26, 2011. The Special
Treatment overlay remains, with a permit approved on February 14, 2012 authorizing
project construction within this area. There is an existing Airport Overlay Zone that limits
the height of obstructions on parts of the Gordon River Greenway Park as described in
Collier County, FL Land Development Code, Section 4.02.06- Standards for
Development in Airport Zones and as attached as Exhibit P to the Management Plan,
which is consistent with State and Federal laws. to '� ; h9m ,4This provides no
potential conflict regarding the uses °r- maflarg „ ^+ ^f the project site. but may require
removal or reduction of trees deemed as obstructions.
The project sites will be identified in all literature and advertising as acquired with funds
from the Florida Communities Trust and operated as natural conservation and outdoor
recreation areas.
III. NATURAL AND CULTURAL RESOURCES
Natural Communities / Invasive Exotic Plants
The two primary natural communities found on both Freedom and Gordon River
Greenway Parks are classified by the Florida Natural Areas Inventory as Scrubby
Flatwoods and Tidal Swamp. There are also smaller areas of Freshwater Tidal Swamp
that contain a mix of wetland hardwood tree species and cabbage palms.
The 39.5 acres of uplands at Freedom Park were once cleared and drained for citrus
production. The grove is long-abandoned and succession of a Scrubby Flatwood
occurred. Much of this area was cleared for the construction of the stormwater filtration
ponds. Previously existing canopy vegetation in this area generally included scattered
