squaring the tree's DBH (diameter at breast height) and multiplying this number by the
appli~able quaiity points factor. If the calculated tree quality points is less than that
given for planted trees in Table 2, then the greater number will apply.

COMPLIANCE.
All improvements shown in the Greenspace Plan shall be constructed and all plant materials
shall be in place and approved by the Augusta-Richmond County Trees & Landscape Department
before a Certificate of Occupancy will be issued for any use of land or structure(s) that is not
exempted from this Ordinance. If at the time of request for a Certificate of Occupancy the required
landscaping is not in place and it can be determined by the Trees & Landscape Department that
unavailability of plant materials or that weather conditions prohibit completion of this planting, then
the developer may, at the discretion of the Executive Director, provide an executed contract binding
for one (1) year from the date of application that provides for the completion of such landscaping
work, and also a performance bond or an irrevocable letter of credit from a federally insured lender in

ILLUSTRATED GUIDE TO IMPLEl\1~NTING
THE AUGUSTA-RICHMOND COUNTY TREE ORDINANCE
1. Purpose
This document provides standards and specification for use in determining
whether or not a development project as defined in Section VIII (A) of the Augusta-
Richmond County Tree Ordinance is in compliance with the provisions of that
Ordinance. Specifically the standards and specifications contained herein shall be used to
determine compliance with the tree protection and tree establishment provisions of the
Greenspace Plan as required by Section VIII (C) of the Augusta-Richmond County Tree
Ordinance.
II. Calculations for Tree Protection and Tree Establishment Elements of a
Greenspace Plan
A. Standard - It must be demonstrated that land to be cleared for development or land being
proposed for development shall have, after development, not less than 1,000 tree quality
points per acre on a given site (Ref. Section VIII (F) of Augusta-Richmond County Tree
Ordinance). In order to receive tree quality points, any planted tree must be provided
with a minimum Tree Protection Zone based upon its mature size as defmed in the tree
list. Trees that are to be preserved on a site must be protected (i.e. tree fences, no
grading, fill or vehicular encroachment) within an area that is defined by a diameter in
feet that is one and one half times the DBH of the tree in inches in order to qualify for
Tree Quality Points. For example:
. A tree with a 40 inch DBH must be protected within a radius of 30 feet from the tree. (Refer to
lllustration 1: Tree Protection Zone)
40" x 1.5 = 60 foot diameter
Radius = Y2 x diameter
= Y2 x 6- = 30 feet
The area of this Tree Protection Zone is calculated as follows:
Area = (pi)(r)2
=3/141 (30)2
=2826.9 square feet
Guidelines for tree protection are found in Section V - IX of this guide.
Tree Quality Points quantify the relative value of one tree to another based on three
,criteria:
1. Species Quality: This is a mixture of objective and subjective measures based
upon maintenance records, scientific research, and the experience of experts in
the field. The relative value of species has been determined specifically for the
Augusta area and environment. Species' quality is ranked in order of increasing
desirability as Acceptable, Recommended, or Preferred.

2.
Space Requirement: This factor applies to trees that are retained on a site. Since
large diameter trees require proportionately larger areas to be set aside as a Tree
Protection Zone, Tree Quality Points are assigned in proportion to this space
requirement.
3.
Expected Mature Value: For trees that are planted on a site, Tree Quality Points
assignment is in proportion to the potential size of the tree species and the
minimum planting space in which that species can develop ina safe and healthy
manner. The mature size is categorized in terms of small, medium, or large.
B. Method: For preserved trees, Tree Quality Points assignment is calculated by
multiplying the (DBH)2 by the Tree Quality Points Factor. If the calculated Tree Quality Points is
less than that given for planted trees, then the greater number shall apply. The Tree Quality
Points Factors for preserved trees are as follows:

c. . Example Calculation: A restaurant is being planned. The number of Tree Quality
Points required for the site calculated by multiplying the area of the site by 1,000 (1.75 acres x
1,000 =1750 Tree Quality Points). The developer wishes to save six existing trees on the site.
The formula for calculating Tree Quality Points for preserved trees is: (DBH)2 x (Quality Points
Factor) = Tree Quality Points. The calculation of Tree Quality Points that would accrue to the six.
preserved trees is as follows:

(12)2 x 0,6 = 86.4 TQPs
(16)2 X 1.4= 358.4TQPs
(10)2 x 1.4 = 140,0 TQPs
(16)2 x 1.4 = 358.4 TQPs
(8)2 x 1.4 = 89.6 TQPs or 91 TQPs*
(4)2 x 1.4 = 22.4 TOPs
Total 1056.6 TQPs
*Note that the TQPs are less than what is given for planted trees, so the greater number will
apply,
The Developer must therefore plant enough trees on the site to make up the difference between
the 1750 required Tree Quality Points and the 1056,6 points he will receive for preserved trees, or
693.4 TQPs. The Tree Protection and Tree Establishment of the Greenspace Plan for the project
show that twenty-nine new trees will be planted on the site for the street yard and parking lot
requirement.
Tree Symbol Species #Trees TQPs . -TotaITQPs

WO Willow Oak 2 x 90 180
RM Red Maple 5 x 90 450
1M Japanese Maple 2 x 30 60
H Holly 2 x 30 60
GR Golden Rain Tree 6 x 30 180
Total TQPS 1410
Quality points are assigned to each tree to be planted by comparing the species rating to the size
at maturity. By adding the individual tree quality points of all twenty-nine trees to be planted, it
is determined that the sum is 1410 TQPs. This exceeds the 693.4 points needed so the Tree
Protection and Tree Establishment Elements of the Greenspace Plan are acceptable.
m. Tree Suedes Lists The following pages list species by size classifications that shall be
used to determine the Quality Rating of trees to be preserved or planted as well as the
quality points. Tree species or cultivars not listed will be considered by the Tree
Commission upon request and quality points assigned accordingly.

be protected from the following damages during all pha,ses of land disturbances and
construction processes, in ~rder to qualify for Tree QualitY Points.
1, Direct physical root damage,
2. 'Indirect root damage.
3. Tnmk and crown disturbances.
B. Direct physical root damage most frequently occurs during site clearing and grading
operations where transport or feeder roots are cut, torn, or removed.
1. Transport and absorptive roots tend to tangle and fuse among the roots of adjacent
trees, The removal of trees with heavy machinery along the outer periphery of a tree
save area can result in considerable damage within the tree save area.
2. The most substantial form of physical root damage for all root types occurs in the
form of cut roots. Roots are cut in grade reduction, or from trenching for
underground utilities, sanitary sewer, or storm sewer lines.
3. . A more subtle form of root damage is the loss of absorptive roots. Absorptive roots
"'normally occur in the top four inches of soil, and can be damaged by the track action
. from a single bulldozer pass. The stripping of top soil within a tree's critical root
zone can totally eliminate its feeder root system. Critical root zone is illustrated:in
illustration 3.
C.
Indirect root damage through site modification can result from positive grade changes,
temporary storage of fill materials, the sedimentation of erosion materials, soil
compaction, and soil chemical changes.
1. Grade changes from fill and sedimentation causes a decrease in soil oxygen levels.
An increase in soil carbon dioxide and other toxic gases can also occur, leadmg to
large areas of anaerobic conditions. Anaerobic soil conditions cause a decrease in the
root respiration process which is essential for the uptake and transport of minerals
and nutrients.
2. Anaerobic soil conditions are also produced soil compaction, the increase in soil bulk
density with a decrease in soil pore space. Compacted soil is also impervious to root
penetration, and thus inhibits root development. Soil compaction is generally caused
by the weight and vibrations of heavy machinery, vehicle parking, and the storage of
fill and/or construction materials within the critical roots zones of trees.
3. Changes in soil chemistry will adversely affect tree survival. The most frequent
occurrence is the change (decrease) in soil acidity by concrete washout which is
highly basic. The leakage or spillage of toxic material such as fuels or paints can be
fatal to trees.

D, Trunk and crown disturbances are generally mechanical in nature and are either caused
directly by clearing and grading machinery, or indirectly by debris being cleared and
falling into trees marked for p,rotection.
t:ir '-1: '~~~ ~;~r';~~Vl.
1, Common forms of damages include stripped bark and cambium, split trunks, and
broken limbs.
2. 'Damage also occurs from the posting of signs such as building permits, or survey
markers on trees.
3. Indirect damage can be caused by the placement of burn holes or debris fires too
close to trees. The possible range of damages include scorched trunks with some
cambial dieback, the loss of foliage due to evaporative heat stress (leaf dissication),
and completely burned trunks and crowns.
V. METHODS OF TREE PROTECTION
A.
Planning considerations. Tree space is the most critical factor in tree protection
throughout the development process, The root systems of trees can easily extend beyond
the drip line of the tree canopy, The root system within the drip line region is generally
c~nsidered to be the critical root zone. (Illustration 3). Disturbance within this zpne can
<!ifec.!ly affect a tree's chances for survival. To protect these critical zones, the foRo~ing
~"t~J?dards shall apply: ~{;"
~ l~
~( ~~
ht'The minimum Tree Protection Zone, shall be an area centered on each tree..with a
... diameter in feet, equivalent to one and one half times the tree diameter in inches,
measured at breast height (Illustration I). Provided, however, in no case shall the
area be less than the minimum Tree Protection Zone for a planted tree of the same
. species found on Table 1, Section VIII (G.7) in the Tree Ordinance for Richmond
County, Georgia.

2. If more than one tree is included in one preserved area, the total minimum preserved
area shall include the minimum Tree Protection Zone for each tree in the preserved
area.
r
3. For initial clearing of the site, an additional area of not less than twenty feet 920) in
width shall be added to the perimeter of the Tree Protection Zones until approved tree
protection devices are erected.
4. Layout of the project site utility and grading plans should accommodate the required
Tree Protection Zones. Utilities must be placed along corridors between Tree
Protection Zones.
5. Construction site activities such as parking, materials storage, concrete washout, bum
hole placement, etc... shall be arranged so as to prevent disturbances within the Tree
Protection Zones.
18
~,
. ,.
. ,
6. No disturbances shall cover within the Tree Protection Zone of trees or stands of
trees without prior approval by the Department of Public Works.
B. Protective Barriers
1, The minimum tree protection device shall be a fence constructed at and around the
perimeter of the Tree Protection Zone, Minimum fence height shall be four feet (4)
(Illustration 4), The Administrator shall approve protective fencing which provides
an adequate level of protection.
2. Tree protection devices shall be erected as soon as practical prior to the start of
construction and shall remain in place until [mal inspection and approval of the
project. Broken or dislodged tree protection devices shall be immediately repaired.
3, All Tree Protection Zones should be designated as such with "Tree Protection Zone"
signs posted visibly on all sides of the fenced in areas. These signs are intended to
inform subcontractors of the tree protection process. Signs requesting subcontractor
cooperation compliance with tree protection standards are recommended for site'
entrances.
4. All designated Tree Protection Zones must be protected from the sedimentation of
erosion materia1. '
a) . Silt screening must be placed along the .outer ,uphill edge of the Tree Protection
Zone. ' 'Minimum fence' height. shall be: four feet (4), (Illustration 4). The
Administrator shall approve protective ,fencing .which:provides "an"adequate level
of protection.
b)' Tree protection devices shall be erected as soon as' practical prior :to ,the start of
construction and shall remain in place until final inspection and approval of the
project. Broken or dislodged tree protection devices shall be immediately
repaired.
5. All tree fencing and erosion control barriers must be installed prior to and maintained
throughout the land disturbance process, and should not be removed until
landscaping is installed.

TECHNICAL TERMS
1. Cambium - Tissue within the woody portion of trees and shrubs which gives rise to the
woody water and nutrient conducting system, and the energy substrate transport system
in trees. Cambium growth activity results in a tree's radial development, i.e, increase in
diameter.
2. Cambial dieback - The irreparable radial or vertical interruption of a tree's cambium,
usually caused by mechanical damage, such as "skinning bark", or from excessive heat.
3. Absorptive roots - A complex system of small annual roots growing outward and
predominantly upward from the system of transport roots. These roots branch four or
more times to form fans or mats of thousands of fine, short, non-woody tips. Many of
these small roots and their multiple tips are 0.2 to 1 mm or less in diameter and less than
2 mm long. These roots constitute the major fraction ofa tree's root system surface area,
and are the primary sites of absorption of water and nutrients.
4. Root collar - The point of attachment of major woody roots to the tree trunk, usually at or
near the ground line and associated with a marked swelling of the tree trunk.
5. Root respiration - An active process occurring throughout the absorptive root system of
,trees, and involving the consumption of oxygen.and sugars,with.the,release of energy and
carbon-dioxide. ,Root respiration facilitates .the uptake 'and transport of minerals and
nutrients essential for tree surviva1.
6. Soil compaction- Achange in soil.physicalproperties which includes an'increase in soil
'weight per unitvolume,.and a decrease in soilpore space. Soil compaction is caused by
repeated vibrations, frequent traffic and weight. As related to tree roots, compacted soil
can cause physical damage, a decrease in soil oxygen levels and an increase in toxic
gases, and can be impervious to new root development.
