SECTION 02150
TREE PROTECTION
PART 1: GENERAL
1.1 RELATED DOCUMENTS: The General Contract Conditions, Drawings, and Division - 1
Specification sections apply to Work of this section.
1.2 SUMMARY: The work of this section consists of retention and protection of trees during
the construction of the project.
1.3 GENERAL REQUIREMENTS:
A. All tree pruning, removal and protection shall adhere to the requirements found in
the City of Fort Collins Tree Management Standards and Best Management
Practices approved by the City Manager 3-31-10.
B. If it appears that the completion of the construction may cause damage to the
branches of any tree, the Service Provider shall contact the City Forester’s
Office. The Forester will make a determination as to whether such damage is
eminent.
C. To prevent or minimize soil compaction, designated routes for equipment and
foot traffic by work crews shall be determined prior to commencing construction
activities. These routes shall be marked at the site, prior to commencement of
construction, with tree protection fencing.
D. Motorized equipment and trailers, including tractors, bobcats, bulldozers,
trackhoes, trucks, cars, and carts shall not be allowed access within tree
protection areas. Should access be necessary within designated tree protection
areas, the existing grade shall be covered with six (6) to eight (8) inches of wood
mulch to help distribute the weight of equipment and to minimize soil compaction
and rutting. Plywood and/or mulch is not acceptable bridging material for driving
over exposed tree roots. Exposed tree roots shall not be driven over. The City
Forester or Project Consulting Arborist shall be notified and shall approve of the
access and driving surface prior to its use.
E. Materials and supplies shall not be stockpiled or stored within the tree protection
area. Should temporary storage be necessary within designated tree protection
areas, the existing grade shall be covered with double, overlapping sheets of ¾
inch thick plywood, or six (6) to eight (8) inches of wood mulch to help distribute
the weight of materials or supplies and to minimize soil compaction.
F. Under no circumstances shall any objects or materials be leaned against or
supported by a tree's trunk, branches, or exposed roots. The attachment or
installation to trees of any sign, cable, wire, nail, swing, or any other material that
is not needed to help support the natural structure of the tree is prohibited.
Standard arboricultural techniques such as bracing or cabling that are performed
by professional arborists are acceptable upon approval by the City Forester or
Project Consulting Arborist.

1.4 DEFINITIONS:
A. TREE PROTECTION AREA: Generally, a tree protection area should consist of
the ground encompassing from 1.5 (minimum) to 2.0 times the distance between
the trunk and dripline, or one linear foot away from the trunk base for every inch
diameter of the trunk, whichever is greater. (See section below). Areas of
ground covered by pavement, buildings, or other permanent structures where the
presence of roots is minimal or negligible, are excluded. The area under or
within the tree's dripline is also referred to as the "Critical Root Zone" (see
below).
1. With groups of trees or where an array effect is present, there may be
discontinuous (non-overlapping) perimeters of tree protection areas,
which result in difficult to maintain or ineffective tree protection fencing. In
these cases, even though tree protection areas do not overlap, they
should be treated as though they do if the distance between the
perimeters of such areas is less than thirty (30) feet. In effect, this will
artificially enlarge the area of tree protection, but will result in a more
clearly defined, manageable area.
B. DRIPLINE: The outermost edge of the tree's canopy or branch spread. The
area within a tree's dripline is all the ground under the total branch spread.
C. CRITICAL ROOT ZONE: Generally, all of the ground area included in the
dripline.
D. DIAMETER (CALIPER): The size (in inches) of a tree's trunk is measured at:
1. six (6) inches above grade for trunk diameters up to and including four (4)
inches;
2. twelve (12) inches above grade for trunk diameters from four (4) inches
up to and including eight (8) inches; and
3. four and a half (4½) feet above grade for trunk diameters greater than
eight (8) inches; in accordance with guidelines established in the "Guide
for Plant Appraisal". All measurements should be rounded to the nearest
inch.
E. HIGH-VALUE SHRUB: Any specimen shrub with an appraised value of $100.00
or more.
F. PROJECT CONSULTING ARBORIST: An independent consultant with a degree
in a field related to arboriculture, and at least five years field experience in tree
preservation or on-site monitoring of public works or construction projects
involving tree retention and protection. The Consultant should be an active
member in the American Society of Consulting Arborists and International
Society of Arboriculture.
1.5 REFERENCE STANDARDS AND GUIDELINES:
A. Service Provider shall comply with applicable requirements and
DocuSign Envelope ID: 84864AFA-242C-4038-A51C-234D91084212
Service Agreement – Work Order Type
8197 Small Landscape & Irrigation Annual Page 57 of 88
recommendations of the most current versions of the following standards and
guidelines. Where these conflict with other specified requirements, the more
restrictive requirements shall govern.
1. ANSI Z133.1-1988: American National Standard for Tree Care
Operations
2. ANSI A300-1994: Standard Practices for Trees, Shrubs and Other
Woody Plant Materials
3. NATIONAL ARBORIST ASSOCIATION STANDARDS: Pruning, Cabling
and Bracing, Fertilization
4. GUIDE FOR PLANT APPRAISAL-8TH EDITION: Authored by the Council
of Tree and Landscape Appraisers; published by the International Society
of Arboriculture
PART 2: PRODUCTS - Not applicable
PART 3: EXECUTION
3.1 CONSTRUCTION REQUIREMENTS: This section provides standards and guidelines for
the retention and protection of trees and high-value shrubs for any proposed public
works or construction project.
3.2 ROOT PRUNING:
A. Avoid cutting surface roots whenever possible. At any location where roots need
to be disturbed or cut, contact the owner representative to review prior to any
disturbance or cutting.
B. Tree roots shall not be pruned or cut unless their removal is unavoidable or
absolutely necessary. The City Forester or Project Consulting Arborist shall be
notified prior to any operation known or suspected to involve cutting of roots two
(2) inches and greater in diameter. The City Forester or Project Consulting
Arborist shall be notified immediately in the event that roots in excess of that
described above are cut, torn, ripped, or otherwise injured.
C. Root cuts from excavation should be done rapidly. Smooth flush cuts should be
made. Backfill before the roots have a chance to dry out and water the tree
immediately.
D. Removal of roots greater than one (1) inch diameter or parts of roots that are
injured or diseased should be performed as follows:
1. Preserve the root bark ridge (similar in structure and function to a branch
bark ridge). Directional root pruning is the recommendation technique
and should be used during hand excavation around tree roots. Roots are
similar to branches in their response to pruning practices. With
directional root pruning, objectionable and severely injured roots are
properly cut to a lateral root, if possible, that is growing downward or in a
favorable direction.

Service Agreement – Work Order Type
8197 Small Landscape & Irrigation Annual Page 58 of 88
2. All roots needing to be pruned or removed shall be cut cleanly with sharp
hand tools, with oversight by the City Forester or Project Consulting
Arborist. No wound dressings shall be used.
3. Recommended root pruning tools:
a. Scissor-type lopper.
b. Scissor-type pruner.
c. Large and small hand saws.
d. Wound scriber.
e. Trowel or small shovel.
f. Garden Fork.
g. Hand broom.
E. Root Pruning Near Sidewalks
1. Root pruning should be done carefully, by hand, to achieve the objective
of reducing future sidewalk problems as well as preserving the trees.
Removing anchoring roots or causing injuries in anchoring roots and root
flares can cause future decay and windthrow hazards. Indiscriminate
cutting of vigorous roots results in their re-sprouting so that several more
new roots may grow from the cut end, back under the sidewalk, thereby
reducing the time between sidewalk repairs. Roots can be managed in
the ground without significant harm to trees, if care is taken to avoid
injuries that lead to root and trunk decay.
2. Directional root pruning is recommended because it considers the tree's
response to root pruning and decay. With directional root pruning, roots
are cut to a large lateral, if possible, that is growing downward or in a
more favorable direction. The pruned root ends will be less likely to re-
sprout, since a large lateral can assume the new terminal role of the root.
3. Proper removal of selected roots or parts of roots can direct roots away
from sidewalks in the future. Procedures for root pruning directly next to
sidewalks are as follows:
a. Hand dig a trench six (6) to eight (8) inches in depth at the edge of
the planting strip and sidewalk.
b. Remove all roots less than two (2) inches diameter in this trench
back to a desirable lateral root, preserving the root bark ridge. If
careful excavation does not reveal a desirable lateral root within
twelve (12) inches of the exposed root in question, then the
exposed root shall be pruned properly so that a minimal amount of
root is removed.
c. Small root bundles, the source of future sidewalk problems,
should also be removed at this time.
F. All roots between two (2) and four (4) inches in diameter should be examined by
the City Forester or Project Consulting Arborist in terms of their role in anchoring
the tree.
1. All roots that contribute significantly to anchorage should be preserved.
Remove all other roots in this size range to sound, downward growing
lateral roots that are at least one half (½) the size of the root being
removed.
2. All roots larger than four (4) inches in diameter are to be preserved unless
DocuSign Envelope ID: 84864AFA-242C-4038-A51C-234D91084212
Service Agreement – Work Order Type
8197 Small Landscape & Irrigation Annual Page 59 of 88
their removal is absolutely necessary. Preservation of large roots may
require:
a. reducing the sidewalk width near the root flare; and/or
b. ramping or bridging the sidewalk over the roots to allow for root
growth.
G. Irrigation lines or any underground fixture requiring excavation deeper than two
inches within the critical root zone shall be accomplished by hand digging to
expose existing roots or by boring under the root system of protected existing
trees at a minimum depth of twenty four inches.
3.3 TREE PROTECTION FENCING:
A. Tree protection fencing shall be installed as designated on construction
documents, and fencing locations should be staked for approval by the
Construction Manager and City Forester or Project Consulting Arborist.
B. Tree protection fences should be constructed of one of the following:
1. Galvanized chain-link - six (6) feet in height. Posts should be installed on
ten (10) foot centers (maximum), at a depth of three (3) feet minimum.
Installation of post shall not result in injury to surface roots or root flares of
trees.
2. Colored (orange), molded plastic construction fencing-five (5) feet in
height supported by 1”x1” or similar sturdy stock.
C. All existing trees to retain in close proximity to any construction as shown the on
the plans shall receive concrete blanket wrapped from trunk base to a minimum
of six (6) foot height.
D. Fencing should be installed to completely surround the limits of tree protection
areas, and should extend at least ten (10) feet beyond the designated
construction limits.
3.4 COMPACTION
A. Mulching over a portion of the root system of existing trees may be directed at
individual locations to adequately prevent soil compaction during construction
activity.
3.5 GRADE CHANGES WITHIN CRITICAL ROOT ZONE
A. When raising the grade around a tree, a dry well is required. When lowering the
grade around a tree, a retaining wall is required. In such instances approval is
required by the owners representative.
B. For sodding operations, do not change grade and for cultivation no more than
two (2) inches of depth shall occur within the drip line of any existing protected
tree.
3.6 INJURIES TO EXISTING PLANTS - DAMAGE PENALTIES:
A. Tree and High-Value Shrub Appraisal: All trees and high-value shrubs will
evaluated and appraised by the City Forester or Project Consulting Arborist, and
a list of all tree values for the project will be on file in the Construction Manager's
DocuSign Envelope ID: 84864AFA-242C-4038-A51C-234D91084212
Service Agreement – Work Order Type
8197 Small Landscape & Irrigation Annual Page 60 of 88
office. Any tree or other plant requiring retention or protection that is not on the
list shall be appraised by the City Forester or Project Consulting Arborist as
necessary to comply with this damage penalty.
B. Documentation for appraisals will consist of :
1. measurement of plant size;
2. identification by common and botanical names;
3. current condition (overall health, injuries, overt hazard status, etc.) and
4. location factors as described in the "Guide for Plant Appraisal".
Photographs may be taken of certain trees and shrubs to document
debilitating condition factors.
C. Trees and other plants designated as requiring retention or protection shall be
identified at on-site conference meeting. Loss of, or partial injury to, any of these
plants due to Service Provider neglect or improper construction activities will
result in a penalty of up to treble damages of the assessed value of the tree as
determined by the City Forester or Project Consulting Arborist. A fine of one-
thousand dollars ($1,000.00) will be levied against the Service Provider for each
incident of construction damage (including construction traffic) within designated
tree protection areas. Any fine shall be independent of any applicable damages
for the assessed value of the tree or tree part.
3.7 SUBMITTALS:
A. Proposed methods, materials, and schedule for root pruning, branch pruning,
and other tree maintenance shall be submitted for approval. The City Forester or
Project Consulting Arborist shall mark the location of root pruning lines in the field
prior to the operation. If possible, root pruning should occur between autumnal
leaf fall and spring foliation. Root pruning during the growing season shall
require approval of the City Forester or Project Consulting Arborist.

the work of this section. Verify that grading operations have been
satisfactorily completed and that topsoil of adequate quantity and quality has
been placed in areas as specified. Verify that the areas to be revegetated are
protected from concentrated runoff and sediment from adjacent areas. Note
previous treatments to the areas such as temporary seeding or mulching and
discuss with the Owner’s Representative how these treatments will affect
permanent revegetation. Report irregularities affecting work of this section to
the Owner’s Representative before initiating work. When the Contractor
begins work under this section, it implies acceptance of existing conditions.
2. Contractor shall notify Owner’s Representative prior to start of work. Owner’s
Representative will be responsible to monitor the work.
B. Pre-planting Inspections:
1. Plant material shall be inspected by an Owner’s Representative before
planting. Inspection of materials may be sequenced by major planting areas
to accommodate efficient planting operations. Plants for inspection must be

removed from the site, replaced and re-inspected before planting. If the
supplier is a local nursery, tagged plants may be inspected at the nursery.
Photographs of the plant materials to be obtained from non-local sources
may be submitted to the City’s Owner’s Representative for preliminary
inspection. This preliminary inspection is subject to final approval of plants at
the job site. The Owner reserves the right to reject plant material at any
stage of construction or guarantee period.
2. Soil amendments, backfill mixes and mulches will be inspected at the site by
the Owner’s Representative before they are used in planting operations.
3. Owner’s Representatives will inspect staked locations and condition of trees
before digging for those plants occurs. Owner’s Representatives will inspect
the location and condition of shrubs in their containers at the proposed
locations before digging commences. Contact Owner’s Representative at
least two days in advance. Tree planting permit must be obtained from City
Forestry prior to any planting.
C. Substantial Completion Inspection:
1. As soon as all planting is completed, a review and preliminary inspection to
determine the condition of the vegetation will be held by the Owner’s
Representatives upon request by the Contractor.
2. The inspection will occur only after the following conditions have been met:
a. Landscape areas will be free of weeds and neatly cultivated;
b. Plant basins shall be in good repair;
c. Irrigation systems shall be fully operational with heads properly adjusted;
d. Debris and litter shall be cleaned up and walkways and curbs shall be

vegetation is in satisfactory growing condition, he will give the Contractor
Written Notice of Acceptance and the Guarantee Period shall begin.
4. Work requiring corrective action in the judgment of the City Representative
shall be performed within the first ten (10) days of the guarantee period. Any
work not performed within this time will necessitate an equivalent extension of
the guarantee period. Corrective work and materials replacement shall be in
accordance with the Contract Documents, and shall be made by the
Contractor at no cost to the Owner.
5. Final approval notice will be given when all deficiencies are corrected.
D. End of Guarantee Period Inspection:
1. At the end of the second full growing season the Owner’s Representatives
will inspect trees for satisfactory condition. The inspection shall take place in
September and the Owner’s Representative shall contact the Contractor
concerning replacements. Replacements may take place the following spring
if deemed proper or necessary.
2. The Contractor is responsible for removal of tree stakes, tree wrap, wire and
webbing at the end of the guarantee period.
1.07 Plant Material Guarantee/Warranty
A. Provide a two growing season warranty (unless noted otherwise) from the date of
Final Approval. Final Approval is hereby defined as the point at which the
Landscape Contractor is 100% complete with installation and is ready for a Final
Approval Review. The Owner's representative will have sole authority to grant
Final Approval. The minimum growing season warranty includes all aspects of
this section including installation, and materials.
B. Guarantee plant material used in this section against defects due to any cause
for a period of two full growing seasons from the date of acceptance of all
work. This guarantee includes insect infestation or infection by disease
organisms.
C. Replace woody vegetation when it is no longer in a satisfactory condition as
determined by the City Representative for the duration of the Warranty Period.
Make replacements within fourteen days of notification from the City
Representative. Replacement planting for trees shall be done in the spring
planting season, except as approved otherwise. If a tree is in marginal condition
at the end of the guarantee period it may be agreeable to both parties to wait
until the end of the growing season before deciding whether to replace that tree.
Plant materials that are replaced during the warranty period shall be replaced
one time at the Contractor's expense. Cost of subsequent replacements, if
required, shall be negotiated with the Owner's Representative. Warranty
replacement plant materials planted within 6 months after Final Approval shall
have the same end of warranty as the original installation. Plants replaced within
6 months of the end of the warranty shall be warranted an additional 6 months
after the date of completion of the initial warranty period.
D. This guarantee will not be enforced should woody vegetation die due to
