TREE PRESERVATION AND REPLACEMENT ORDINANCE Page 1
Section 1: FINDINGS, INTENT AND STATEMENT OF PURPOSE
Columbus, Georgia, is situated in an area covered with a wide variety of
deciduous and evergreen trees and shrubs which are a vital part of the heritage
passed to us by nature and our forefathers.
Trees are recognized to be a valued asset providing a healthier and more
beautiful environment in which to live. Trees are economically beneficial in
attracting new residents and tourists. Tree preservation enhances the value and
marketability of property and, thereby, promotes the stability of residential
neighborhoods making them more livable and desirable, and thus helps prevent
the emergence of blighted neighborhoods, slum conditions and urban sprawl.
Trees aid in preventing erosion, storm drainage, siltation of streams and
reservoirs, and flash flood damage. Trees are valuable in providing shade and
cooling effects, and in preventing air, noise, and visual pollution.
The purpose of this chapter is to:
(a) Make Columbus, Georgia a more attractive and healthy environment in
which to live, and better control stormwater runoff, noise, glare, heat, and
soil erosion;
(b) Provide the necessary information to facilitate development
project design, plan review, and enforcement processes in order that the
provisions of this Ordinance are administered in the most effective, efficient
and economical manner;
(c) Establish and maintain the maximum sustainable amount of tree cover on
public and private lands in the city;
(d) Maintain city trees in a healthy and non-hazardous condition; and
(e) Establish and maintain appropriate diversity in tree species and age
classes to provide a stable and sustainable urban forest.

(b) On sites 2 acres or smaller, additions or expansions greater than 5,000
square feet shall be subject to this Ordinance. This includes additions
cumulatively totaling more than 5,000 square feet since the adoption of the
Ordinance. On sites greater than 2 acres, additions or expansions greater than
10,000 square feet to an existing structure shall be subject to this
Ordinance. This includes additions cumulatively totaling more than 10,000
square feet since the adoption of the Ordinance.
(1) Any site or development which falls under the provisions of this Ordinance
by virtue of additions or expansions as defined in this subsection shall be
required to meet the applicable Tree Density Unit (TDU) requirements as
established hereafter only and without regard to any specified placement of
trees contained in Section 8 (a), Parking Areas, and (b) (1) Perimeter
Plantings.
(2) To determine the required number of TDU?s specified in this sub-section,
you may either:
(A) Calculate the total surface area of any proposed new impervious surface
and/or improvements and plant new trees sufficient to meet the required TDU?s
for that area (existing trees elsewhere on the site may not be counted with
this option;) or
(B) Calculate required TDU?s for entire site area according to zoning
classification and with this option, existing trees on the site may be counted
to achieve required TDU?s.
Page 13
(c) For planned developments including the operations of clearing or grading,
the Owner shall be required to follow at a minimum the
standards set forth herein and the standards of stabilization as set forth in
the Erosion Control Ordinance. Plantings shall not be required until a
Certificate of Occupancy is requested for the developed parcels and at that
time only the plantings for each developed parcel should be required. Plantings
shall be completed prior to the issuance of a Certificate of Occupancy or
performance of a Final Building Inspection. This shall ensure that the proper
plantings are established for each use as well as provide for the appropriate
timing of plant installation. (See Section 11, Tree Planting Standards,
Subsection (b) Planting Specifications and Section(10) Out of Season Planting,
and Section 14, Fiscal
Surety for procedures providing for delayed plantings in the
appropriate planting season.)
(d) Redevelopment of a site shall require the application of the
Ordinance. Redevelopment is defined as the demolition and rebuilding or

required TDU?s for that area (existing trees elsewhere on the site may
not be counted with this option;) or
(B) Calculate required TDU?s for entire site area according to zoning
classification and with this option, existing trees on the site may be
Page 14
counted to achieve required TDU?s.
(f) Any site or development which falls under the provisions of this
Ordinance by virtue of redevelopment as specified in (d) above shall be
required to meet the applicable Tree Density Unit (TDU) requirements
only and without regard to any specified placement of trees contained in
Section 8 (a), Parking Areas, and (b) (1) Perimeter Plantings.
(g) (e) The provisions of this Ordinance shall apply to all public
entities and owners of public property within Columbus, Georgia and it shall be
unlawful for said owners to fail to comply with all provisions of this
Ordinance.
Section 7: DENSITY REQUIREMENTS
(a) How Site Density Requirements Are Calculated:
(1) Formula for Calculation. The Tree Density Units required by
the Tree Preservation and Replacement Ordinance may be achieved by
counting existing trees to be preserved, planting new trees, or some
combination of the two as represented by the formula: Total Tree Density Units
(TTDU) = Existing Tree Density Units (ETDU) + Replacement Tree Density Units
(RTDU) (see below). The tree density requirement must be met whether or not a
site had trees prior to development.
(2) Total Tree Density Units (TTDU) Requirements for a Site. The
Total Tree Density Unit requirement for a site is the minimum Tree
Density Units (TDU) required to be maintained on a developed site. It is
calculated by multiplying the number of site acres by the appropriate Tree
Density Unit (TDU) number for the applicable zoning classification. Determine
the affected site acreage by starting with the area of the parcel(s) of land on
which the project is located. Subtract the area of any utility easement and
pond or lake and dam over one (1) acre in area.
(3) Existing Tree Density Units (ETDU). Existing Tree Density
Units (ETDU) is the density of existing trees to be preserved on a
site. Trees that exist in any utility easements cannot be counted
toward meeting tree density requirements. The ETDU is calculated by converting
the diameter of individual existing trees to density factor units. (See Tables
B-1 and B-2 below.)
Page 15
(4) Replacement Tree Density Units (RTDU). Replacement Tree Density Units
(RTDU) is the density of new trees to be planted on a site, excluding utility
easements. Calculate the RTDU by subtracting the ETDU from the TTDU. The
density factor credit for each caliper size of replacement (new) trees is shown
in Table A below.
(b) Low and Medium Density Single Family Residential Lots and
Subdivisions.
Prior to the issuance of (1) a Site Development Permit or a
Residential Development Permit for any property to be developed as a
residential subdivision within a low density single family residential or
agricultural zoning classification, or (2) a Building Permit for any lot not in
a previously approved single family residential subdivision for which a Tree
Protection and/or Tree Planting Plan has been approved, a Tree Protection
and/or Planting Plan shall be prepared and approved indicating compliance with
the appropriate tree density standards of density units per acre which
corresponds to the zoning classifications below:
Zoning Classification Tree Density Units
A-1 Agricultural 12
R-1 Low Density Residential 10
R-1A Low Density Residential 8
R-2 Low Density Residential 6
R-3 Medium Density Residential 4
Trees must be protected and preserved in accordance with the provisions of
Section 10: Tree Protection During Construction Standards of this Ordinance and
any trees required to be planted to meet the requirements herein shall be
planted in accordance with the provisions of Section 11: Tree Planting
Standards of this Ordinance and shall be a species listed on Appendix A,
"Recommended Maturing or Small Maturing Tree Planting Lists" of this Ordinance.
All trees required by any required zoning buffer or on any individual lot as
provided hereafter or by any other legal requirement shall be counted in
calculating whether said property meets the required TDU standard.
Page 16
Additionally, every residential lot containing 7,500 square feet area or
greater shall have a minimum of two trees located thereon, one of which must be
between the front set back line and the right-of-way. At least one of said
trees on lots containing 7,500 square feet or greater area shall be a large
maturing / canopy / shade tree. Lots containing less than 7,500 square feet
of surface area shall have a minimum of one tree which may be located anywhere
on the lot. These individual trees per lot may be counted as part of the
required tree density units per acre for the development, but they may be an
additional requirement if the appropriate units per acre requirement is met
elsewhere on the site. This tree per lot requirement shall apply to the
developer or home builder, whoever is responsible for obtaining the building
permit for the individual lot, but if it is to be applied to the home builder,
the developer will be given credit on the whole project for the trees which
will be required to be planted on the lots which may be built upon
later.
In the event final planting of the one or two tree per lot requirement of
Subsection 7 (b) or other required plantings cannot be accomplished on a single
family residential lot in a previously approved residential subdivision due to
the planting season, inclement weather, or other exigent circumstances whereby
the owner desires to move into said home prior to said planting,
owners/developers may submit a ?Request for Delay Affidavit? to the Arborist.
In the case of a single family residential home being built on any lot or tract
zoned as specified above in this sub-section 7 (b) greater than two acres in
surface area, the tree density units required to be met for said site shall be
those applicable to two acres irrespective of the greater size of said lot or
tract upon which said home is built.
(c) All Other Residential Lots and Subdivisions, Commercial and
Industrial Developments.
Prior to the issuance of a Site Development Permit or Residential
Development Permit, or Building Permit for any lot not in a previously approved
single family residential subdivision if a site is eligible for Self Permitting
under the provisions of Section 17C, Soil Erosion & Sedimentation Ordinance,
for any property to be developed within any zoning classification other than
those specified for Low and Medium Density Single Family Residential Lots and
Subdivisions above, a Tree Protection and/or Planting Plan
Page 17
shall be prepared and approved indicating compliance with a tree density
standard of ten (10) density units per acre.
All trees required by any required zoning buffer, street or perimeter trees and
trees required to be planted in any parking lot as provided hereafter or by any
other legal requirement shall be counted in calculating whether said property
meets the required TDU standard.
Trees to be counted in arriving at required TDU standards must be
protected and preserved in accordance with the provisions of Section 10: Tree
Protection During Construction Standards of this Ordinance and any trees
required to be planted to meet the requirements herein shall be planted in
accordance with the provisions of Section 11: Tree Planting Standards of this
Ordinance and shall be a species listed on Appendix A , "Recommended Large
Maturing or Small Maturing Tree Planting Lists" of this Ordinance.
Section 8: ADDITIONAL REQUIREMENTS
In addition to the provisions of Section 7, Density Requirements,
above, the following requirements also apply:
(a) PARKING AREAS
(1) For lots one and one/half (1 1/2) acres or less. Trees may be
planted in the parking areas but are not required to be planted there. However,
a minimum of seventy per cent (70%) of the required TDU's for said lots shall
be either retained or planted as the case may be in the front or side yards of
said lots, or adjacent to the city roadways.
(2) For lots larger than one and one-half (1 1/2) acres containing
parking areas with a total of twenty (20) or less spaces. In parking areas of
twenty (20) or less spaces, landscaping may be provided in landscaping islands
and/or medians as provided below, but is not mandatory so long as every parking
space is within 60 feet or less from a perimeter or ?street? tree, or other
large maturing canopy/shade tree retained or planted on the development.
(3) For lots larger than one and one-half (1 1/2) acres containing
parking areas of twenty (21) or more spaces. In parking areas of twenty one
(21) or more spaces, landscaping shall be provided in landscaping islands
and/or medians. Landscaping islands shall be placed so that no line of more
than sixteen (16) adjacent (side by
Page 18
side) parking spaces exists. All landscaping islands and medians shall have
raised curbs or wheel stops around them, however the use of at-grade planting
areas in parking lots to promote storm water runoff treatment and to supplement
irrigation needs is encouraged.
Interior linear landscape medians. Interior linear landscape medians may be
provided between parking bays. Landscape medians shall be a minimum eight (8)
foot width, measured from back of curb to back of curb. Each tree planted in
an interior landscape median is required to have a minimum of 200 square feet
of planting area. When the landscape median extends to the end of a parking
bay, a contiguous median end island, perpendicular to the landscape median, is
required. Combination drainage swale/planting strips are permitted, in lieu of
curbed and sloped islands, provided that adequate drainage is provided for the
chosen species.
Interior landscape islands. Interior landscape islands may be
provided within parking lots and other paved areas. The first tree planted in
an interior landscape island is required to have a minimum of 200 square feet
of planting area, with at least eight (8) feet in one direction, measured from
back of curb to back of curb. If the landscape island contains more than one
tree, eighty (80) square feet of planting space shall be added for each
additional tree. The interior landscape islands may be contiguous with an
interior landscape median or a perimeter planting strip.
Landscape end islands. Landscape end islands shall be provided at
the end of a parking bay. Each tree planted in an end island is
required to have a minimum of 200 square feet of planting area, with a minimum
length equal to the length of the adjoining parking space, and a width of at
least eight (8) feet, measured from back of curb to back of curb. If the
landscape island contains more than one tree, eighty (80) square feet of
planting space shall be added for each additional tree. The landscape end
islands may be contiguous with an interior landscape median or a perimeter
planting strip.
Required plantings. Interior and terminal landscape islands for a
single row of parking spaces shall be planted with a least one (1) large
maturing canopy/shade tree. Interior or terminal islands for a double row of
parking spaces shall contain not less than two (2) large maturing canopy/shade
trees.
Large maturing canopy/shade trees must be planted or retained within the
landscape medians and/or islands so that each parking space is 80 feet or less
from a tree in an interior planting area,
Page 19
median or island, or 60 feet or less from a perimeter or ?street? tree, or
other large maturing canopy/shade tree retained or planted on the
development. If significant tree save areas or natural areas, or planned
alternatives which exceed the requirements of this Ordinance as to numbers of
trees and/or spacing distances exist within a parking area, the City Arborist
may make such exceptions to these requirements, as he or she deems appropriate
in their sole discretion.
Minimum planting area. The minimum unpaved landscape area per tree in said
landscaping islands shall be 200 square feet with a minimum
dimension of 8 feet. Understory trees may be substituted for large
maturing canopy/shade trees in any landscape median or island if such tree
would be within 20 feet of an overhead utility line.
Curbs and wheel stops. Trees shall be planted a minimum of three (3) feet from
any curb or wheel stop, so as to prevent injury to trees by vehicle bumpers.
Where landscaped areas are located adjacent to vehicle overhangs, trees shall
be planted in line with the striping between parking spaces in order to avoid
injury to trees by vehicle bumpers.
Landscaping of islands and medians. All landscape islands within
parking lots shall be one hundred percent (100%) landscaped with trees (as
specified above), evergreen shrubs (not to exceed 30" in height at maturity),
ground cover (excluding those requiring mowing), mulch, and/or flowers in
mulched beds in the area within three (3) feet of the base of the tree. The
same planting requirements shall apply to medians in parking lots. Grass may
be used in landscape medians and islands so long as it stops three (3) feet
from the base of the tree. Pedestrian traffic through landscape medians and
islands should be directed away from the trees' critical root zones and toward
appropriate pathways
through appropriate landscaping.
Preplanting preparation of compacted soil. All landscape islands and medians
where trees and shrubbery will be planted shall be prepared to a uniform depth
of two and one-half (2.5) feet of uncompacted soil. The final soil in the
landscape islands and medians shall be obtained on site or imported from a
suitable source. Dumping of construction debris, trash, concrete residue,
paint residue or other items toxic to trees and plants shall not be allowed in
landscape islands and medians. No gravel, stone, or other impervious material
greater than one (1) inch in diameter shall be allowed in the landscape islands
or in a landscape
Page 20
median within eight (8) feet radius of a tree planted in an interior linear
landscape median, unless it is used as mulch. Site-lighting standards should
be coordinated for new planting locations or avoided in planting islands for
Ordinance-required trees.
(4) Exceptions.
Multi-level or covered parking areas are exempt from the requirements of
subparagraphs (1) , (2) AND (3)above.
The provisions of sub-paragraphs (2) and (3) above relating to landscape
medians and islands and maximum distances between parking spaces and trees do
not apply to areas used principally for motor vehicle, boat or mobile home
sales, storage or display lots, and loading and shipping docks and areas of
heavy truck traffic thereto, which shall be clearly delineated to separate them
from employee and customer parking areas.
All other requirements of this Ordinance, including but not limited to
perimeter planting and tree density requirements for the whole
development, shall apply to such exempted areas, however.
(b) PERIMETER PLANTINGS
(1) General: In all developments and substantial improvements on
parcels excepted by the provisions of the Buffering, Screening and
Landscaping Ordinance (Code of Ordinances Section 18A-71 et seq; Ord. No.
99-25, 4/29/99; Ord No. 00-58, 6/13/00), other than areas zoned C-1 and CRD on
the Official Zoning Atlas of Columbus, Georgia, the following provisions shall
apply:
A continuous perimeter planting strip is required along the perimeter of the
property. The perimeter planting strip shall be a minimum width of 10 feet.
Perimeter planting strips may occur within required buffers or yards. The
minimum number of trees required in the perimeter planting strip shall be one
(1) large maturing tree for every fifty (50) linear feet of perimeter, or
portion thereof, or one (1) small maturing tree for every thirty (30) linear
feet of perimeter, or portion thereof. If a small maturing tree is planted
next to a large maturing tree, the maximum distance between the two trees shall
be thirty (30) feet, subject to the grouping provision below. Existing trees
to be preserved in the landscape strip may count toward perimeter planting.
Page 21
At least fifty percent (50%) of the trees in the perimeter planting
strip must consist of large maturing trees, except that no large
maturing tree shall be planted within twenty (20) feet of an overhead utility
line. Trees may be grouped or spaced to allow sight corridors. In the event
of grouping of trees as permitted herein, a portion of said grouped trees may
be planted inward of the perimeter planting strip if necessary to maintain a
minimum distance between trees of 20 feet.
Where evenly spaced street trees exist within the public right-of-way, planted
trees should be staggered to prevent conflict with existing trees and
accommodate the full potential growth of the trees. Each tree planted in a
perimeter planting strip is required to have a minimum of 200 square feet of
planting area which may not be encroached upon by parking spaces or driveway
surfaces.
(2) The provisions of this sub-section as to perimeter plantings also apply to
the portions of those Low and Medium Density Single Family Residential Lots and
Subdivisions specified in Section 7 (b) of this Ordinance where said
subdivision or lot abuts the right of way of a public freeway, arterial or
collector street as defined by the Ordinances of Columbus, Georgia.
(3) Storm Water Detention and Retention Facilities: In addition to the above
requirements, a visual screen shall separate and screen all storm water
detention and/or retention facilities adjacent to a public street or
right-of-way from said public street or right-of-way, and any adjoining or
contiguous property. The screen shall be a minimum of thirty six (36) inches
in height within twenty-four (24) months after planting and may be formed
through creation of a planted hedge, wall, earth berm or combination of such.
When using an earth berm, the slope shall not exceed three to one (3:1) with a
maximum crown width of two (2) feet, and shall be planted with turf or other
landscaping materials. The visual screen may be included in the required
perimeter planting strip.
(4) Non Residential Uses in Residential Zoned Areas: All provisions of this
section apply to all non-residential uses on parcels zoned for residential
purposes. (This includes but is not limited to clubhouses, public uses
including buildings, structures and uses of land by a unit of government such
as schools, libraries, parks, playgrounds, recreation centers and fire
stations, public, private and parochial schools, churches and other places of
worship, convents, monasteries, recreational/ meeting facilities constructed in
connection with a residential development or owned and operated by a
neighborhood association, utility substations and wireless communication
facilities.
Page 22
Section 9: TREE PROTECTION AND PLANTING PLAN REQUIREMENTS
(a) Tree Protection and Planting Plan Required - All applications for site
development permits shall be accompanied by a Tree Protection and Planting Plan
drawn to a standard scale and size which includes the following:
(1) A tree and root protection zone plan for:
(A) all existing trees on the public right-of-way;
(B) all trees to be retained for credit under any of the
provisions of this Ordinance; and
(C) TDU and any applicable parking lot and/or perimeter planting requirements
and attainment.
(2) A planting plan for all trees required to be planted under
any of the provisions of this Ordinance on public and private property. Plans
that are only for required street planting may be in written form. This plan
shall be approved prior to construction where street trees may be effected.
(3) This Tree Protection and Planting Plan may be included on
other required plans.
(4) For subdivisions, this plan may be in narrative form with
sketch sufficient to identify tree save areas and how the project will meet the
requirements of this Ordinance. For residential subdivisions, a copy of this
plan shall be forwarded to the Building Inspections and Code Department. All
proposed site plans for any development for which a planting plan has been
approved shall make reference to the specified number of Tree Density Units
(TDU?s) or trees for that lot, and shall make reference to the builder?s
acknowledgement to meet these previously imposed requirements.
(b) Tree replacement and protection - When trees retained or planted as
required by this Ordinance die or are removed for any reason, except in single
family residential lots, they must be replaced during the next suitable
planting season in a manner, quantity and size agreed upon by the owner and the
Arborist. If they cannot agree, then the determination shall be made by the
Tree Board, with right of appeal by any aggrieved party. Trees shall be
allowed to grow to their natural height and form. Topping of any
Page 23
tree necessary to attain compliance with any provision of this Ordinance is
prohibited.
Section 10: TREE PROTECTION DURING CONSTRUCTION STANDARDS
The following standards shall apply to trees proposed to be preserved for
credit toward meeting the minimum required Tree Density Units on a property.
(a) Tree and Root Protection Zone.
The root system within the dripline is the Critical Root Zone (CRZ). To
protect these critical root zones, a Tree Protection Area (TPA) shall be
established around each tree or group of trees to be retained.
(1) The Tree Protection Area shall include no less than the total area beneath the
tree canopy as defined by the dripline of the tree or group of trees
collectively, unless prior approval is received from the City Arborist.
(2) Layout of the project site utility and grading plans shall
avoid disturbance in the Tree Protection Area. Trenching shall not be allowed
within the Tree Protection Areas, unless prior approval is received from the
City Arborist.
(3) Construction site activities, including but not limited to
parking, materials storage, concrete washout, burnhole placement, shall not be
allowed within the Tree Protection Areas.
(4) Root disturbance due to cuts or fill shall not be allowed
within the Tree Protection Areas. All exposed roots one (1) inch and greater
in diameter at the edge of the Tree Protection Area shall be pruned with a
clean cut flush to the soil edge.
(5) Soil compaction shall not be allowed within Tree Protection
Areas.
(6) Erosion and sedimentation control measures shall be installed in a manner
designed to prevent the accumulation of sediment within the Tree Protection
Areas.
(b) Protective Barriers. Tree protection devices shall be installed as shown
on the plans or otherwise completely surround the Tree Protection Areas.
Page 24
(1) All tree protection fencing shall be installed prior to and
maintained throughout the land disturbing and construction process, and shall
not be removed until final landscaping is installed.
(2) Tree protection fencing shall consist of chain link, orange
laminated plastic, wooden post and two rail fencing, or other equivalent
restraining material.
(c) Extra TDU Credits: Any tree with a single-stem trunk diameter of 21" or
greater (at DBH) that is shown on the plan will receive double the normal Tree
Density Unit credit if appropriate tree protection standards are employed for a
ground area equivalent to 1.5 feet in radius for each 1 inch in diameter (at
DBH). These trees must be represented on the plan by a circle the size of the
Protected Root Zone.
(d) Signage: Posting "Tree Save Area" signs is recommended in addition to the
required tree protection fencing. Signs requesting subcontractor cooperation
and compliance with the tree protection standards are recommended for site
entrances.
(e) Pruning: Pruning of tree limbs to provide clearance for equipment and
materials or for any other reason shall be done in accordance with standard
arboricultural practices.
(f) Encroachment: If encroachment into a Tree Protection Area occurs which
causes irreparable damage to one or more trees, based on the assessment of the
City Arborist, the damaged tree(s) shall no longer count toward the required
Tree Density Units for the property and must be replaced.
Section 11: TREE PLANTING STANDARDS
The following standards shall apply to all trees and shrubs proposed to be
planted for credit toward meeting the minimum required Tree Density Units on a
property.
(a) Plant Material Specifications.
(1) All plant material shall meet American Standard of Nursery Stock standards.
(2) Trees selected for planting must be free from injury, pests,
disease, nutritional disorders or root defects, and must be of good
vigor in order to assure a reasonable expectation of survivability.
Page 25
(3) Large Maturing (Canopy) Tree species shall be a minimum of eight (8) feet
in height and have a caliper of at least two (2) inches immediately after
planting. See Appendix A: Recommended Large Maturing and Small Maturing Tree
Planting Lists for suitable species choices.
(4) Small Maturing (Understory) Tree species shall be a minimum of
five (5) feet in height and have a caliper of at least one and one-half (1 1/2)
inches immediately after planting. See Appendix A: Recommended Large Maturing
and Small Maturing Tree Planting Lists for suitable species choices.
(5) No Large Maturing Tree species shall be planted within twenty
(20) feet of overhead wires.
(6) All plantings that die or are destroyed must be replaced, except in single
family residential lots, during the next suitable planting season. Trees which
are planted on single family residential lots to meet the requirements of this
Ordinance must be alive and in good vigor at the time of the sale of the
property, or the developer or builder who planted the tree shall replace the
same during the next suitable planting season.
(b) Planting Specifications.
Plantings shall be installed to current nursery industry standards.
See Appendix B for an illustrative example.
(1) The diameter of the planting hole shall be a minimum of three
(3) times the diameter of the root ball.
(2) The planting hole sidewalls shall be scored or roughened to
eliminate the smooth, slick surface caused by the shovel or auger.
(3) If containerized material is to be planted, any circling roots
shall be cut by slicing the root ball vertically from top to bottom in two to
three well spaced lines around the root ball with a sharp knife.
(4) The root ball shall rest on undisturbed soil in the planting
hole with the top of the root ball on level with the natural ground
level or slightly raised (not to exceed a height of two (2) inches above the
natural ground level).
Page 26
(5) Any tree planted with the top of the root ball below natural
ground level shall not be counted towards the required Tree Density
Units for the property.
(6) The soil used to backfill around the root ball shall be
uncompacted, native soil free of rocks, trash, or any construction
debris.
(7) Stakes and guy wires should only be installed when absolutely necessary.
Supporting devices shall not interfere with vehicular or pedestrian movement
and shall be removed after twelve (12) months.
(8) Mulch in the form of pine straw, pine bark, or wood chips shall
be evenly distributed over the planting hole to a settled depth of two (2)
inches.
(9) Permanent built-in or temporary irrigation systems shall be
installed to ensure the plants will survive the critical establishment period.
(10) Out-of-season planting is discouraged. Property
Owners/Developers may submit a "Request for Delay Affidavit" to allow for plant
installation to occur at a time which better coincides with the normal planting
season (November 1st to March 31st).
Section 12: ALTERNATIVE COMPLIANCE
The intent of this Tree Protection and Replacement Ordinance is to
insure that a minimum density of trees is maintained on all developed sites.
Occasionally, this intent cannot be met because a project site will not bear
the required density of trees. To provide some alternatives in such cases, two
methods of compliance are acceptable:
- planting at a location on public property or an appropriate
conservation easement remote from the project site; or,
- contributing to the Columbus, Georgia Tree Replacement Fund.
The following standards have been established for administering these
alternative compliance methods:
Page 27
The City Arborist must review and approve all requests for alternative
compliance. In no instance, shall 100 percent of the required site density
factor be met through alternative compliance. As many trees as can reasonably
be expected to survive must be planted on the site in question.
The land disturbance permit will only be issued after the City Arborist has
approved the request and received the necessary documentation and/or funds.
(a) Off-Site Planting.
If trees are to be planted at another location, the following criteria must be
observed:
The off-site location should be in the same area of the City as the
project site and will be selected by joint consultation between the
developer and the City Arborist. If they are unable to agree upon a mutually
acceptable site, then the Tree Board will select the site.
A Tree Planting Plan meeting all applicable standards required in
Section 9 of this Ordinance must be reviewed and approved.
The following note must be shown on the approved plan:
"A Tree Planting Plan addendum for this project shall be submitted to the
Columbus, Georgia City Arborist within 30 days from the date of this land
disturbance permit. This plan shall include the species, size and location of
trees to be planted off-site to meet the tree density deficit shown. Release
of this project is subject to approval of this plan as well as verification of
the installation of the trees."
(b) Tree Replacement Fund.
As another method of alternative compliance, Columbus, Georgia will
accept donations to the Columbus, Georgia Tree Replacement Fund, which will be
used for the sole purpose of planting trees on public property in the same area
of the City as the project site.
(1) Calculating Contribution Amounts:
Contribution calculations are based on two-inch caliper replacement
trees with a value of $220.00, representing the average size and cost of
materials, labor and guarantee for trees planted in the Columbus, Georgia area.
Page 28
To determine the appropriate contribution, first calculate the Density Factor
Deficit (DFD) or unit value that cannot be planted on the site. Divide the DFD
by .5 (the unit value of a 2? caliper replacement tree) and multiply by $220.00.
EXAMPLE: A 2.2 acre site has a required Total Tree Density Units (TTDU)
standard of 22.0, Existing Tree Density Units (ETDU) OF 11.4, and can only
accommodate Replacement Tree Density Units (RTDU) of 9.0.
Determine the Density Unit Deficit (DUD) using the formula:
DUD = TTDU - ETDU - RTDU
In this example, DFD = 22.0 ? 11.4 ? 9.0 = 1.6
Determine the acceptable contribution amount as follows:
1.6 divided by .5 multiplied by $220.00 = $704.00
(2) Fund Administration:
The Columbus, Georgia Tree Replacement Fund will be administered by the
Landscape and Forestry Division. A quarterly report shall be submitted to the
City Manager showing amounts collected, amounts spent, and the types and
locations of trees planted. The report will be made available to the Mayor and
Council upon their request.
Section 13: INSPECTIONS
(a) Inspections.
Inspections shall be performed at any time during the development
process, and from time to time, as determined by the City Arborist.
Said inspections shall be performed by the Arborist or one of her
designees, which may include officials of the Building Inspections and Code
Department for single family residential lots. Prior to the release of the
certificate of occupancy, final plat approval or final building inspection, an
inspection will be performed to assure compliance with the Tree Protection and
Planting Plan. Any required irrigation must be operational at this time. Hose
bibs and other watering devices specified on the plans will be verified, and
all plantings and trees retained for TDU credit will be inspected. Any
certificate of occupancy or final building inspection may be granted prior to
any required plantings having been fully installed if a ?Request for Delay
Affidavit? has been filed and approved by the Arborist.
Page 29
(b) Maintenance Inspection.
Any planted materials that are dead or missing at the time of that
inspection must be replaced by the responsible party.
The City Arborist shall provide the responsible party with a written evaluation
of what trees need to be replaced and the time frame within which replacement
is to occur.
Any trees in a state of decline will be noted and subject to monitoring at
later dates. If such trees die, they will become the responsibility of the
current owner to replace.
Section 14: VARIANCES
Written requests for a variance, filed on forms prescribed by the City Arborist
and sworn to by the owner of the property concerned, are required. The
requests shall state clearly what adjustments or
requirements are being requested and reasons such adjustments are
warranted and such supplementary data as is deemed necessary to
substantiate the adjustment shall accompany the request. The City
Arborist shall have the authority to grant variances not to exceed
twenty percent (20%) of the minimum or maximum standards of this
Ordinance. Where requested variances exceed twenty percent of the
minimum or maximum standards of this Ordinance, or if the applicant is
dissatisfied with the action of the City Arborist on a request for a lesser
variance or any other finding of the City Arborist, the application for
variance or any appeal of a decision of the City Arborist shall be made to the
Tree Board.
Where the City Arborist, in the case of requests for variances not to exceed
twenty percent (20%) of the minimum or maximum standards of this Ordinance, or
the Tree Board, if the requested variance exceeds twenty percent of the minimum
or maximum standards of this Ordinance, finds that extraordinary hardships or
practical difficulties may result from strict compliance with these regulations
and/or the purposes of these regulations may be served to a greater extent by
an alternative proposal, the Board shall be authorized to grant a variance from
the requirements of this Ordinance where such modification will not be contrary
to the public interest where, due to special conditions, a literal enforcement
of the provisions of this Ordinance will, in an
Page 30
individual case, result in unnecessary hardship provided that such
variances shall not have the effect of nullifying the intent and purpose of the
Ordinance. Such variances may be granted in such case of unnecessary hardship
upon the finding of the Arborist or Tree Board as the case may be that:
(a) The granting of the variance will not cause substantial detriment to the
public health, safety, or welfare; be injurious to other property; or impair
the purpose and intent of this Ordinance.
(b) There are extraordinary and exceptional conditions pertaining to the
property in question that would result in a particular hardship to the owner,
as distinguished from a mere inconvenience, if the strict letter of these
regulations were carried out.
(c) The strict application of this Ordinance would deprive an
applicant of reasonable use of the land, or would create an unnecessary
hardship as distinguished from a mere inconvenience.
(d) Such special circumstances are not the result of actions of the
applicant taken subsequently to the adoption or amendment of this
Ordinance.
The City Arborist or Tree Board, as the case may be, may approve, modify or
deny the requested adjustment, but shall approve or modify only if it
determines that approval of any adjustments would not be contrary to the intent
of this chapter, and that literal enforcement of the above standards would be
impractical and would result in unreasonable and unnecessary hardships. The
City Arborist, or Tree Board shall act as expeditiously as possible
on all requests for variance and appeals. The Tree Board shall approve or
reject any request for a variance of more than twenty percent (20%) of the
minimum or maximum standards of this Ordinance, or affirm or reverse any appeal
from a decision of the Arborist, within forty (40) days after the filing
thereof. If a meeting of the Tree Board has not been scheduled within the next
thirty (30) days of the filing of a request for variance of more than twenty
percent (20%) or appeal, the Chair shall call a meeting. The decision of the
Board shall be issued within ten (10) days of the consideration of the request
or appeal. Notification of all actions on requests for variance or appeal,
whether by the Arborist or Tree Board, shall be forwarded to the applicant by
Page 31
certified or registered mail, return receipt requested, and posted in a
conspicuous place, or in the office of the City Arborist, in the form of a
short, concise statement of the action taken. Within fourteen (14) days after
posting of decision, but not thereafter, any decision of the City Arborist or
Tree Board may be appealed by the applicant. The appeal of any decision by the
City Arborist shall be to the Tree Board, and the appeal of any decision of the
Tree Board shall be filed with the Clerk of Council for action by the Council
of Columbus. The appeal to the Council of Columbus is a de novo appeal, and
the Council may affirm, modify, or reverse the ruling of the Tree Board.
Variances under this Ordinance shall be granted under the same
procedures and conditions as set forth in Section 22-37 of the Columbus Code of
Ordinances, excluding the notification of property owners, except that the Tree
Board will be acting as the appellate body on all matters under this Chapter
rather than the Board of Zoning Appeals. The Tree Board is granted the same
powers for hearing appeals and granting variances involving this Chapter as the
Board of Zoning Appeals is granted in hearing the appeals before it.
Section 15: NUISANCES, DISEASE, INFECTION, AND EMERGENCIES
(a) Public nuisances.
(1) The City Arborist has the authority to declare as a nuisance any tree or
shrub or parts thereof growing on public or private property, and interfering
or endangering the use of the public streets or sidewalks or obscuring sign
distances and creating a traffic hazard on intersections or endangering the
life, health, safety or property of the public. The City Arborist shall notify
in writing the owner or interested parties of such tree or shrub of the
existence of the nuisance and give a fifteen (15) day period of time for
contracting for correction or removal of the nuisance or for requesting a
hearing.
(2) If the owner or interested parties have not corrected or removed the
nuisance or contracted for correction or removal of the nuisance within such
fifteen (15) day period, the City Manager or his designated agent shall hold a
hearing not less than fifteen (15) days nor more than thirty (30) days
following the notice of the City Arborist, at a time and place certain within
Columbus, Georgia. The owner or parties in interest shall be given the right
to file an answer to the notice, to appear in person, or be represented by an
attorney, and give testimony,
Page 32
at the time and place fixed, as to why he or she has not complied with the
notice from the City Arborist. Rules of evidence prevailing in courts of law or
equity shall not control in hearings before the City Manager or his designated
agent. The City Manager or his designated agent shall determine at the hearing,
on the basis of the evidence presented, whether or not the tree or shrub is a
nuisance to the public of Columbus, Georgia and the owner?s responsibility
therefor.
(3) If the City Manager or his designated agent determines that the
tree or shrub is a nuisance, he or she shall issue an order, which shall be
served upon the owner or parties in interest, requiring them to remove or
correct the nuisance within fifteen (15) days. If not corrected or removed
within such period, the City Arborist shall cause the nuisance to be corrected
or removed and the cost shall be assessed to the owner or interested parties.
(4) The cost of the correction or removal shall be a lien against the real
property upon which the tree or shrub is or was situated. Said lien shall be
prepared and entered by the Finance Department and recorded in the office of
the Clerk of the Muscogee County Superior Court in the same manner which liens
for costs for removal of weeds and other vegetation are filed.
(5) The owner or parties in interest shall pay the full amount due on such lien
to the Director of Finance of Columbus, Georgia within thirty (30) days of
perfection of such lien, and if such lien is not paid in full within thirty
(30) days of the perfection of such lien, the owner or parties in interest
shall pay twenty-five (25) percent of the total lien amount plus seven (7)
