3. Existing Roadway Improvements and Right-of-Way Adjacent To and Near the Site
• Eagle Road is improved with three lanes and no curb, gutter, or sidewalk, all within 73 to 120-
feet of right of way (33 to 60-feet from centerline) abutting the site. Sidewalk improvements
exist along Eagle Road north of, south of, and opposite the site.
• Plaza Drive is improved as a three-lane, 40-foot street section with vertical curb, gutter, and
detached sidewalk on the east side of Eagle Road near the site's northeast corner.
4. Existing Access: The site currently has three unimproved driveways and one curb-cut driveway
onto Eagle Road.
5. Site History: ACHD has not previously reviewed this site for a development application.
6. Adjacent Development: Several former single family structures north of the site are converting to
commercial retail use.
Development Impacts
7. Trip Generation: This development is estimated to generate 2,627 additional vehicle trips per day
(VTD), based on the Institute of Transportation Engineers Trip Generation Manual for 16,622
square feet of pharmacy; 7,600 square feet of restaurant; and 4,400 square feet of specialty retail.
8. Impact Fees: There will be an impact fee that is assessed and due prior to issuance of any building
permits. The assessed impact fee will be based on the impact fee ordinance that is in effect at that
time.
9. Current Condition of Impacted Roadways:
Roadway Frontage Functional Traffic Count Level of Speed
Classification Service* Limit
Eagle Road 290' Minor Arterial 17,370 north of SH 44 Exceeds 30 MPH

*Acceptable level of service for a five-lane principal arterial is "E" (37,000 ADT).
**ACHD does not set level of service thresholds on State Highways.
10.Capital Improvements Plan (CIP)/Five Year Work Plan (FYWP): There are currently no
roadways, bridges or intersections in the general vicinity of the project that are currently in either the
Five Year Work Plan or the Capital Improvements Plan.
B. Findings for Consideration
1. Eagle Road
Right-of-Way Policy: District policy requires 96-feet of right-of-way on arterial roadways (Figure
72-F1 B). This right-of-way allows for the construction of a 5-lane roadway with curb, gutter, 5-foot
concrete detached sidewalks and bike lanes.
Sidewalk Policy: District policy requires 7-foot wide attached (or 5-foot detached) concrete
sidewalk on all collector roadways and arterial roadways (7204.7.2).
Applicant Proposal: The applicant is proposing to construct 8-foot detached concrete sidewalk
along Eagle Road abutting the site.
2 ERZ-10-08 EDR-58-08 EDR-59-08
Staff Comment/Recommendation: Eagle Road transitions from a 3-lane arterial north of the
site to a 5-lane arterial south of the site. The applicant will be required to dedicate 38-feet of right-
of-way from the centerline of Eagle Road abutting the site. This will allow for future widening of
Eagle Road to extend the two southbound travel lanes from SH-44 to the Plaza Drive intersection.
This will allow for dual left turn lanes from Plaza westbound to Eagle southbound in the event that
a signal is installed at this intersection in the future. The applicant will also be required to
construct the detached sidewalk 41-feet from the centerline of Eagle Road South of Plaza Drive,
and transitioning to 25-feet from the centerline north of Plaza Drive. The applicant will be required
to align the sidewalk with existing improvements north and south of the site, and provide an
easement for the sidewalk located outside of the right-of-way.
2. Driveways
Access Policy: District policy 7207.8 states that direct access to arterials and collectors is
normally restricted. The developer shall try to use combined access points. If the developer can
show that the use of a combined access point to a collector or arterial street is impractical, the
District may consider direct access points. Access points for proposed developments at
intersections should be located as far from the intersection as practical, and in no case closer
than as illustrated on Figure 72-F4, unless a waiver for the access point has been approved by
the District Commission.
Driveway Offset Policy: District policy 72-F4 (1) requires driveways located on arterial
roadways near a signalized intersection to be located a minimum of 440-feet from the signalized
intersection for a full-access driveway and a minimum of 220-feet from the signalized intersection
for a right-in/right-out only driveway.
Commercial Driveways: District policy 7207.9.3 restricts commercial driveways with daily traffic
volumes over 1,000 vehicles to a maximum width of 36-feet. Most commercial driveways will be
constructed as curb-cut type facilities if located on local streets. Curb return type driveways with
15-foot radii will be required for driveways accessing collector and arterial roadways.
Driveway Paving: Graveled driveways abutting public streets create maintenance problems due
to gravel being tracked onto the roadway. In accordance with District policy, 7207.9.1, the
applicant should be required to pave the driveway its full width and at least 30-feet into the site
beyond the edge of pavement of the roadway and install pavement tapers with 15-foot radii
abutting the existing roadway edge.
Applicant Proposal: The applicant is proposing to enter into a cross access agreement with
adjacent properties to the north and south, and to create a four-way intersection at Eagle Road
and Plaza Drive by constructing one 40-foot wide curb-return type driveway aligning with Plaza
Drive. This driveway will serve as a combined access to the businesses on the west side of
Eagle Road.
Staff Comment/Recommendation: District staff is supportive of the applicant's proposal.
District staff recommends a modification of policy to allow a 40-foot driveway in order to match the
width of Plaza Drive on the east side of the road.
3. Eagle Road — Plaza Drive Intersection
Although the intersection of Eagle Road and Plaza Drive is ranked 17`h on the District's signal
priority list for warrants, its proximity to signals on Eagle Road to the north and south present
challenges, and the District does not currently have plans to install a signal at this location. In the
event that a signal is installed at this location in the future, the District will likely require that
access points to the south be closed, and that those parcels take all access from the signalized
intersection. The City of Eagle should take proper measures to ensure that cross-access
easements are in place to allow for access consolidation.
3 ERZ-10-08 EDR-58-08 EDR-59-08
4. Other Access
Eagle Road and SH-44 are classified as a minor arterial and principal arterial roadway,
respectively. Other than access specifically approved by ACHD during the development process,
direct lot access to these roads is prohibited.
C. Site Specific Conditions of Approval
1. Dedicate 38-feet of right-of-way from the centerline of Eagle Road abutting the parcel. The right-
of-way purchase and sale agreement and deed must be completed and signed by the applicant
prior to scheduling the final plat for signature by the ACHD Commission or prior to issuance of a
building permit (or other required permits), whichever occurs first. Allow up to 30 business days
to process the right-of-way dedication after receipt of all requested material. The District will
purchase the right-of-way which is in addition to existing right-of-way from available Corridor
Preservation Funds.
2. Construct a minimum 5-foot detached concrete sidewalk no closer than 41-feet from the
centerline of Eagle Road south of Plaza Drive abutting the site. The sidewalk shall transition to
align and connect with existing improvements to the north and south of the site. Provide a
sidewalk easement for the sidewalk located outside of the right-of-way.
3. Construct one 40-foot wide curb-return driveway onto Eagle Road, aligning with Plaza Drive
(centerline-to-centerline). The driveway shall be paved its full width at least 30-feet into the site.
4. Other than access specifically approved with this application, direct lot access to Eagle Road and
SH-44 is prohibited.
5. Comply with all Standard Conditions of Approval.
D. Standard Conditions of Approval

other required permits), which incorporates any required design changes.
9. Construction, use and property development shall be in conformance with all applicable
requirements of the Ada County Highway District prior to District approval for occupancy.
10. Payment of applicable road impact fees are required prior to building construction. The assessed
impact fee will be based on the impact fee ordinance that is in effect at that time.
4 ERZ-10-08 EDR-58-08 EDR-59-08
11. It is the responsibility of the applicant to verify all existing utilities within the right-of-way. The
applicant at no cost to ACHD shall repair existing utilities damaged by the applicant. The
applicant shall be required to call DIGLINE (1-811-342-1585) at least two full business days prior
to breaking ground within ACHD right-of-way. The applicant shall contact ACHD Traffic
Operations 387-6190 in the event any ACHD conduits (spare or filled) are compromised during
any phase of construction.
12. No change in the terms and conditions of this approval shall be valid unless they are in writing
and signed by the applicant or the applicant's authorized representative and an authorized
representative of the Ada County Highway District. The burden shall be upon the applicant to
obtain written confirmation of any change from the Ada County Highway District.
13. Any change by the applicant in the planned use of the property which is the subject of this
application, shall require the applicant to comply with all rules, regulations, ordinances, plans, or
other regulatory and legal restrictions in force at the time the applicant or its successors in interest
advises the Highway District of its intent to change the planned use of the subject property unless
a waiver/variance of said requirements or other legal relief is granted pursuant to the law in effect
at the time the change in use is sought.
E. Conclusions of Law
1. The proposed site plan is approved, if all of the Site Specific and Standard Conditions of Approval
are satisfied.
2. ACHD requirements are intended to assure that the proposed use/development will not place an
undue burden on the existing vehicular transportation system within the vicinity impacted by the
proposed development.

facilities. Said letter of review is to be provided within thirty calendar days after the date of the
plan review conference.
3) Revisions: The developer is responsible to provide utilities with any revisions to preliminary
plans. Utilities may request an updated plan review meeting if revisions are made in the
preliminary plans which affect the utility relocation requirements. Utilities shall have thirty days
after receiving the revisions to review and comment thereon.
4) Final Notification: The developer will provide highway entities, utility owners and the UCC with
final notification of its intent to proceed with right of way improvements and include the
anticipated date work will commence. This notification shall indicate that the work to be
performed shall be pursuant to final approved plans by the highway entity. The developer shall
schedule a preconstruction meeting prior to right of way improvements. Utility relocation activity
shall be completed within the times established during the preconstruction meeting, unless
otherwise agreed upon.
Notification to the Ada County UCC can be sent to: 50 S. Cole Rd. Boise 83707, or Visit

PRELIMINARY TREE MAINTENANCE GUIDELINES
INTRODUCTION
This guideline establishes the minimum standard of care and maintenance of the City of
Eagle's Regulated Trees. These standards apply to all persons who own or are engaged in
the business of repairing, maintaining, or preserving these trees. The following standards
of care are set forth for pruning (including utility, fire and traffic encroachment),
planting, watering, soil and nutrient requirements, insect, and disease. Guidelines for
selecting an arborist are also given. These standards and guidelines are based on sound
arboricultural principles and are applicable to trees, shrubs and woody plants.
CARE OF REGULATED TREES
All owners of Regulated Trees are to follow the required maintenance standards set forth
in this guideline. If special pruning or situations require a variance from these
Standards, it is the responsibility of the project arborist and property owner to clarify why
the changes are needed and review them with the City Forester.
PROHIBITED ACTS
Improper maintenance may constitute a prohibited act as defined by the Eagle City Code,
Chapter 8-2A-7 (G) and a violation which may be subject to penalty.
The following permitted and prohibited maintenance practices for protected and
designated trees apply.
A.Excessive Pruning
Except for clearance pruning of utility lines, traffic or abating a Public
Nuisance, excessive pruning shall be considered a prohibited act.
B.Topping
Topping shall be considered a prohibited act. Seek alternatives to topping.
C. Other prohibited actions
Taking any action foreseeably leading to the death of a tree or permanent damage to its
health, including but limited to excessive pruning, cutting, girdling, poisoning, over
watering,unauthorized relocation or transportation of a tree, or trenching, excavating,
altering the grade, or paving within the dripline area of a tree .
STANDARDS FOR PRUNING REGULATED TREES
The most compelling reason to prune trees is to develop a strong, safe framework. All
work to be performed on Regulated Trees shall be in accordance with the following
standards.
A. Specifications
All specifications for working on protected and designated trees shall be written and shall
be administered by a certified and qualified arborist, and shall be designed to promote the
preservation of tree structure and health.
Pge1of5
C:\Documents and Settings\bcerda\Local Settings\Temporary ternet Files\Content.Outlook VG'9PXMEX\Tree Maintenance Guidelines.doc
B.Industry Standards
All work on Regulated Trees shall be in accordance with the most current edition of the
following industry standards: (see Performance Standards. Standard Practices for Tree
Care Operations -ANSI A300-most recent version; Safety Standards, ANSI Z133.1-most
recent version.
PRUNING MATURE TREES
There are four types of pruning that may be required for use on mature Regulated
Trees (see ISA Tree Pruning Guidelines). Prior to entering the tree,the tree worker is
required to be familiar with these types of pruning as stated in the Pruning Standards,
ANSI, A300-2008. `Species-specific' pruning promotes the natural shape of the tree (i.e.
excurrent, decurrent, vase-shaped, fast growing, etc.).
A. Types of Pruning
• Crown Cleaning
• Crown Thinning
• Crown Raising
• Crown Reduction
B.Tree Injury
Climbing and pruning practices shall not injure the tree except for the pruning cuts.
C. Timing of Pruning
To reduce the probability of insect infestation,disease or infection, the following
seasonal restrictions apply, except when public safety is a concern.
• All species: Do not prune during the flush of spring shoot growth
• Trees with thin•bark: Do not prune in summer when sun scald injury may be a
factor
• Deciduous trees (leafless in winter): Best pruned November- February
• Hazardous trees of any species may be pruned any time of the year for abatement
reasons;,
PRUNING DISTRESSED TREES
Distressed trees require as much leaf area as possible to overcome stressed conditions. To
avoid additional injury,the following measures shall be followed for these trees.
A.Injury or Disturbance
If a tree has been damaged by injury or disturbance, delay pruning until deadwood
becomes evident (typically 1-3 years after injury). Crown cleaning is then recommended.
B.Neglect
Trees that have received little or no care or maintenance may need moderate crown
thinning,reduction of end weights or entire crown restoration.
PRUNING YOUNG TREES
Page 2 of 5
C:\Documents and Settings\bcerda\Local Settings\Temporary Internet Files\Content.Outlook\XP9PXMEX\Tree Maintenance Guidelines.doc
The average life expectancy for trees growing in harsh urban conditions is 7-10 years.
By pruning trees early, it will improve life expectancy and is a proven, cost-effective
measure. Added benefits are also reflected in safer trees with fewer branch failures.
For trees that serve as a replacement for protected or designated trees, they shall be
pruned in the following way:
• Young trees should be pruned during the second year after planting to improve
their structure, and only minor crown cleaning every 3-7 years thereafter. Refer to
ISA Tree Pruning Guidelines.
• Do not top the main leader except to position the lowest main branch. Other main
branches should be spaced at least 18-inches apart to alleviate a tight grouping
branches.
• Select permanent branching and allow temporary low branching on the lowest
part of the trunk to remain.
FERTILIZING STANDARDS
This section outlines performance standards for fertilizing and applies only if fertilizing is
specified. Fertilizing mature trees is generally not necessary.Fertilizing may be specified
for trees that will be impacted by upcoming disturbance, grade changes or a modified
environment. Benefits gained from the increase stored resources may aid the tree to
overcome the stress caused by disturbance.
A. Specifications
Fertilizing, if necessary shall be tailored to the specific needs of the trees and be based on
a soil sample. A plan should include coverage of the following items:
• Method of application
• Material and Rates
• Timing
WATERING SCHEDULE
Newly installed trees planted, including drought tolerant species, are dependent upon
supplemental irrigation until established,typically for two years. Periods of extreme heat,
wind or drought may require more or less water than recommended in these
specifications♦The method and amount that is applied may vary depending upon soil
composition, heat,,:wind, planted in turf or ground cover, periods of abnormal rainfall or
in poorly drained soils. The watering of protected or designated trees or their
replacements shall follow these standards:
A.New trees
During the establishment period(1-2 years)trees should be watered thoroughly to their
root depth as frequently as needed. A watering schedule is to be submitted at the
preconstruction meeting. The schedule is to include watering frequency and quantity. The
minimum standards shall be as follows:
• 1-3 months in the ground: 4 times per month or as necessary
• 4-6 months in the ground: 4 times per month or as necessary
• 7-12 months in the ground: 4 times per month or as necessary
Page 3 of 5
C:\Documents and Settings\bcerda\Local Settings\Temporary Internet Files\Content.Outlook\XP9PXMEX\Tree Maintenance Guidelines.doc
B. Mature trees
• Most species: 4 times per month during irrigation season (usually March through
September)
• For oaks already in the vicinity of irrigated conditions, automatic sprinklers or
regular watering shall not be allowed to spray on or within three feet of the trunk.
The water shall not be allowed to pool or drain towards the trunk.
INSECT AND DISEASE CONTROL
Generally, insect populations do not threaten tree health to the point of mortality. More
often, when their populations become too great they create a nuisance. For example, scale
on tulips or aphids feeding on purple leaf plums produce sticky honeydew that may be a
nuisance if dripping on cars or at a storefront entry. Occasionally, however, pests such as
Oak or Tussock Moth larvae can defoliate and severely damage a tree. If action is
warranted, Integrated Pest Management (I.P.M.) suggests that the pest source be
identified and targeted with a specific and timely treatment-. If insects or disease can lead
to the death of a protected or designated tree, then it is the responsibility of the property
owner to evaluate the condition according to the following guidelines and treat the
problem in a timely fashion to prevent further deterioration of the tree.
A.Insects
Nontoxic materials should be used whenever possible to control leaf-chewing insects.
B.Disease and Decay- above ground
Disease such as heart-rot decay that erodes the health or weakens the structure of a
protected or designated tree may compromise the safety of people or property. It is the
property owner's responsibility to correct a known hazardous condition in a timely
fashion.
• Consult with a certified arborist for remedy possibilities, for example, pruning out
infected branches,thinning,-or the application of a chemical treatment.
C.Disease-:below ground notes:
Often, a poor landscape design surrounding old trees encourages harmful and often lethal
diseases. The following conditions that favor a disease environment must be avoided.
• :'.Conditions to avoid: Compacting of the soil within the tree's dripline, adding fill
dirt,rototilling,trenching, removing soil from the tree root area, and excessive or
regular watering on or near the tree trunk area and planting incompatible water-
loving plants within the tree's dripline. Combined with poorly-drained soil, these
factors often activate normally dormant fungi to become opportunistic and infect
the tree to cause the decline and eventual death of the tree. This decline can be
slow and may not be evident for many years.
• Landscape Design. When planning landscaping around a protected or designated
tree, an evaluation of the tree and soil must be performed to determine if there is a
disease present. If the tree is diseased and landscaping will contribute to decline,
permanent damage or render it hazardous, it is the obligation of the property
Page 4 of 5
C:\Documents and Settings\bcerda\Local Settings\Temporary Internet Files\Content.Outlook Vff9PXMEX\Tree Maintenance Guidelines.doc
owner to take reasonable measures to reduce or eliminate the conditions that may
cause the decline of the protected or designated tree.
• To identify cultural conditions that may lead to diseases such as Oak Root
Fungus, Verticillium, Phytophthora or other soilborne fungi, consult with a
Certified Arborist
• Use plants under oaks that have low to moderate water needs.
D.Foliar disease
Leaf spot or galls may be chronic or reoccur with specific seasons. Though many of these
diseases destroy leaf tissue and become unsightly, they may not significantly reduce the
trees health and therefore need not be treated.

PRELIMINARY TREE PROTECTION AND PRESERVATION PLAN
GUIDELINES
PROTECTION OF TREES DURING CONSTRUCTION
INTRODUCTION
The objective of this guideline is to reduce the negative impacts of construction on trees
to a less than significant level. Trees vary in their ability to adapt to altered growing
conditions. Mature trees have established stable biological systems in the preexisting
physical environment. Disruption of this environment by construction activities interrupts
the tree's physiological processes causing depletion of energy reserves and a decline in
vigor, often resulting in the tree's death. Typically,this reaction may develop from one to
twelve years or more after disruption. The tree protection regulations are intended to
guide a construction project to insure that appropriate practices will be implemented in
the field to eliminate undesirable consequences that may result from uninformed or
careless acts, and preserve both trees and property values. "Tree Protection and
Preservation Plan"means a plan prepared by a certified arborist qualified in tree
protection and preservation that outlines measures to protect and preserve trees on a
project. This plan shall include requirements for preconstruction; treatments during
demolition and/or construction; establish a tree protection zone for each tree; tree
monitoring and inspection schedule; and provide for continued maintenance of those
trees after construction according to the requirements in this guideline.
Typical negative impacts that may occur during construction include:
• Mechanical injury to roots,trunk or branches
• Compaction of soil (compression of the soil structure or texture by any means that
creates an upper layer that is impermeable; compaction is injurious to roots and
the health of a tree) , which degrades the functioning roots and inhibits the
development of new ones and restricts drainage, which desiccates roots and
enables water mold fungi to develop.
• Changes in existing grade which can cut or suffocate roots
• "Alteration of the water table -either raising or lowering
• , Microclimate change, exposing sheltered trees to sun or wind
• Sterile soil conditions, associated with stripping off topsoil.
TREE PROTECTION AND PRESERVATION PLAN
Prior to commencement of a development project, the property owner shall have prepared
a Tree Protection and Preservation Plan. The Tree Protection Plan will be prepared by
an International Society of Arboriculture certified arborist qualified in tree protection and
preservation to assess impacts to trees,recommend mitigation to reduce impacts to a less
Page 1 of 9
C:\Documents and Settings\bcerda\Local Settings\Temporary Internet Files\Content-Outlook\XP9PXAEX\Construction preservation procedure.doc
than significant level, and identify construction guidelines to be followed through all
phases of a construction project.
PRE-CONSTRUCTION REQUIREMENTS
The following six steps shall be incorporated within the Tree Protection and Preservation
Plan prior to building permit issuance.
A. Site Plan
On all improvement plans for the project,plot accurate trunk locations and the `dripline
areas'of all trees or groups of trees to be preserved within the development area. In
addition, the plans shall accurately show the trunk diameter, dripline and clearly indicate
the tree protection zone to be enclosed with the specified tree fencing as a bold dashed
line.
B.Verification of tree protection
The project arborist or contractor shall verify, in writing, that all preconstruction
conditions have been met(tree fencing, erosion control, pruning,etc.) and is in place.
Written verification must be submitted to and approved by the Planning and Zoning
Department prior to demolition, grading or building permit issuance.
C.Pre-construction meeting
The demolition, grading and underground contractors,construction superintendent and
other pertinent personnel are required to meet with the Project Arborist at the site prior to
beginning work to review procedures,tree protection measures and to establish haul
routes, staging areas, contacts,watering, etc.
D.Protective Tree Fencing for Protected Trees,Street Trees or
Designated Trees
Fenced enclosures shall be erected around trees to be protected to achieve three primary
goals, (1)to keep the foliage crowns and branching structure clear from contact by
equipment,materials and-activities, (2)to preserve roots and soil conditions in an intact
and non-compacted state and,(3)to identify the tree protection zone (TPZ) in which no
soil disturbance is permitted and activities are restricted.
Size and type of fence
All trees to be preserved shall be protected with five or six (5' - 6') foot high chain link
fences.Fences are to be mounted on two inch diameter galvanized iron posts, driven into
the ground to a depth of at least 2-feet at no more than 10-foot spacing. This detail shall
appear on grading, demolition and improvement plans.
Area to be fenced
The fences shall enclose the entire area under the canopy dripline or TPZ of the tree(s)
to be saved throughout the life of the project, or until final improvement work within the
area is required,typically near the end of the project. Parking Areas: If the fencing must
be located on paving or sidewalk that will not be demolished,the posts may be supported
by an appropriate grade level concrete base. Tree fencing shall be erected before
Page 2 of 9
C:\Documents and Settings\bcerda\J.+ral Settings\Temporary Internet Files\Content.Outlook\P9PXMEX\Construction preservation procedure.doc
demolition, grading, or construction begins and remain in place until final inspection of
the project permit, except for work specifically required in the approved plans in which
case the project arborist or City Forester must be consulted.
`Warning' Sign
Warning signs shall be prominently displayed on at least four sides of the trees. The signs
shall be a minimum of 24 x 24 -inches and clearly state: 1) State champion tree--
"CAUTION - Tree Protection Zone - This tree is the Idaho State Champion English
Oak. It has been valued at$59,500. The value reflects the condition, significance, and
importance of this tree as a community asset. Entering the Critical Root Zone with heavy
equipment will damage the tree and is not allowed under penalty by the General
Contractor." 2)Remaining two trees-- "CAUTION - Tree Protection Zone Entering
the Critical Root Zone with heavy equipment will damage the tree and is not allowed
under penalty by the General Contractor."
E.Tree Protection Zone or(TPZ)
Each tree to be retained shall have a designated TPZ identifying the area sufficiently
large enough to protect the tree and roots from disturbance. The TPZ shall be shown on
all site plans for the project. Improvements or activities such as paving, utility and
irrigation trenching and other ancillary activities shall occur outside the TPZ. Unless
otherwise specified,the protective fencing shall serve as the TPZ.
1. Activities prohibited within the TPZ include:
• Storage or parking vehicles,building materials, refuse, excavated spoils or
dumping of poisonous materials on or around trees and roots. Poisonous materials
include,but are not limited to, paint, petroleum products, concrete or stucco mix,
dirty water or any other material which may be deleterious to tree health.
• The use of tree trunks as a winch support, anchorage, as a temporary power pole,
sign posts or other similar function.
• Cutting of tree roots by utility trenching, foundation digging,placement of curbs
and trenches and other miscellaneous excavation.
• Soil disturbance or grade change
• Drainage changes:
2. Activities permitted or required within the TPZ include: notes:
• ' Mulching. During construction, wood chips may be spread within the TPZ to a 4-
to 6-inch depth, leaving the trunk clear of mulch to help inadvertent compaction
and moisture loss from occurring. The mulch may be removed if improvements or
other landscaping is required. Mulch material shall be 2-inch unpainted, untreated
wood chip mulch or approved equal.
• . Irrigation, aeration, fertilizing or other beneficial practices that have been
specifically approved for use within the TPZ.
F.Tree Pruning,Surgery and Removal
Prior to construction, various trees may require that branches be pruned clear from
structures, activities, building encroachment or may need to be strengthened by means of
Page 3 of 9
C.\Documents and Settingstbcerda\Local Settings\Temporary Internet Files\Content.Outlook\XP9PXMEX\Construction preservation procedure.doc
mechanical support or surgery. The most compelling reason to prune is to develop a
strong, safe framework and tree structure. Such pruning, surgery or the removal of trees
shall adhere to the following standards:
1. Pruning limitations:
• Minimum Pruning: If the project arborist recommends that trees be pruned, and
the type of pruning is left unspecified,the standard pruning shall consist of
`crown cleaning' as defined by ISA Pruning Guidelines and the following:
o Excessive Pruning means: removing in excess, one-fourth(25 percent) or
greater, of the functioning leaf, stem or root area. Pruning in excess of 25
percent is injurious to the tree and is a prohibited act. Excessive pruning
typically results in the tree appearing as a `bonsai', 'lion's-tailed', `lolly-
popped' or overly thinned.
o Unbalanced Crown. Excessive pruning also includes removal of the leaf or
stem area predominantly on one side, topping, or excessive tree canopy or
crown raising. Exceptions are when clearance from overhead utilities or
public improvements is required or to abate a hazardous condition or a
public nuisance.
o Roots. Excessive pruning may include the cutting of any root two (2)
inches or greater in diameter and/or severing in excess of 25 percent of the
roots.
• Trees shall be pruned to reduce hazards and develop a strong, safe framework.
• Maximum Pruning: Maximum pruning should only occur in the rarest situation
approved by the City Forester.No more than one fourth(25 percent) of the
functioning leaf and stem area may be removed within one calendar year of any
protected or designated tree,or removal of foliage so as to cause the unbalancing
of the tree. It must be recognized that trees are individual in form and structure,
and that pruning needs may not always fit strict rules. The project arborist shall
assume all responsibility for special pruning practices that vary from the standards
outlined in this guideline.
• Tree-Workers Pruning shall not be attempted by construction or contractor
personnel, but shall be performed by a qualified tree care specialist or certified
tree worker,according to specifications contained within this guideline.
ACTIVITIES DURING CONSTRUCTION&
DEMOLITION NEAR TREES
Soil disturbance or other injurious and detrimental activity within the Tree Protection
Zone (TPZ) is prohibited. If an injurious event inadvertently occurs, then the following
mitigation is required:
A. Soil Compaction
If compaction of the soil occurs, it shall be mitigated as outlined as follows in the Soil
Improvement sub-section.
Page 4 of 9
C:\Documents and Settings\bcerda\Local Settings\Temporary Internet Files\Content.Outlook\XP9PXMEX\Construction preservation procedure.doc
Soil Improvement
During development, compaction of the soil is the largest single factor responsible
for the decline of oaks and older trees.Ninety percent of the damage to the upper
eighteen inches of soil occurs during the first pass of heavy equipment- and
cannot be reversed. Every effort to avoid compaction of soil porosity within the
tree protection zone shall be taken at all times. When required by the conditions
of Discretionary Development Approval for a project or as mitigation for injury or
a prohibited action, the following performance standards for improvement of
compacted or damaged soil shall be implemented:
A.Aeration
Soil that is damaged or compacted within the dripline of protected or designated
trees shall be loosened or aerated to promote root growth and enhance tree
vitality. One of the following aeration methods shall be specified an in effort to
correct compacted soil conditions:
• Vertical Mulching: auger holes 2 to 4-inch diameter, 2 to 3-feet deep, on
4-foot centers and backfilled with porous material such as perlite,
vermiculite or volcanic rock.
• Radial Trenching: with an air excavator, excavate a soil trench 3 to 6-
inches wide and a minimum of 12-inches deep from (approximately) 3-
feet from the trunk out to the dripline area. The trenches shall radiate out
from one foot apart at the closest point.
• Soil-fracturing with a pneumatic air-driven device.
• Subsurface injections under moderate hydraulic pressure using a three foot
probe and applied on 3-foot centers under the dripline.
B. Grading Limitations within the Tree Protection Zone
• Grade changes outside of the TPZ shall not significantly alter drainage to the tree.
• . Grade changes within the TPZ are not permitted.
• Grade changes under specifically approved circumstances shall not allow more
than 6-inches of fill soil added or allow more than 4-inches of existing soil to be
removed from natural grade unless mitigated.
Injury Mitigation
A mitigation program is required if the approved development will cause drought stress,
dust accumulation or soil compaction to trees that are to be saved. To help reduce impact
injury, one or more of the following mitigation measures shall be implemented and
supervised by the project arborist as follows:
1. Irrigation Program. Irrigate to wet the soil within the TPZ to a depth of 24-inches to
30-inches. Or, apply sub-surface irrigation at regular specified intervals by injecting on
approximate 3-foot centers, 10- gallons of water per inch trunk diameter within the TPZ.
Duration shall be until project completion.
2. Dust Control Program. During periods of extended drought, wind or grading, spray
wash trunk, limbs and foliage to remove accumulated construction dust.
Page 5 of 9
C\Documents and Settings\bcerda\Local Settings\Temporary Internet Files\Content.Outlook�9PXMEX\Construction preservation procedure.doc
3. Soil Compaction Damage. Compaction of the soil is the largest killer of trees on
construction sites due to suffocation of roots and ensuing decline of tree health. If a
compaction event to the upper 12-inch soil horizon within the tree protection zone has or
will occur by any means, then one or more of the of the following mitigation measures
shall be implemented.
• . Mitigation. If inadvertent compaction of the soil has occurred within the TPZ, the
soil shall be loosened by one or more of the following methods to promote
favorable root conditions: vertical mulching, soil fracturing, core-venting, radial
trenching or other method approved by the City Forester.
C.Trenching,Excavation and Equipment Use
Trenching, excavation or boring activity within the TPZ is restricted to the following
activities,conditions and requirements if approved by the City Forester. Mitigating
measures shall include prior notification to and direct supervision by the project arborist.
1.Notification. Contractor shall notify the project arborist a minimum of 24 hours in
advance of the activity in the TPZ.
2. Root Severance. Roots that are encountered shall be cut to sound wood and repaired.
Roots 2- inches and greater must remain injury free.
3. Excavation. Any approved excavation, demolition or extraction of material shall be
performed with equipment sitting outside the TPZ. Methods permitted are by hand
digging,hydraulic or pneumatic air excavation technology. Avoid excavation within the
TPZ during hot, dry weather.
• If excavation or trenching for drainage,utilities, irrigation lines, etc., it is the duty
of the contractor to tunnel under any roots 2-inches in diameter and greater.
• Prior to excavation for foundation/footings/walls, grading or trenching within the
TPZ, roots shall first be severed cleanly 1- foot outside the TPZ and to the depth
of the future excavation. The trench must then be hand dug and roots pruned with
a saw, sawzall,narrow trencher with sharp blades or other approved root pruning
equipment.
4. Heavy Equipment. Use of backhoes, steel tread tractors or any heavy vehicles within
the TPZ is prohibited unless,approved by the City Forester. If allowed, a protective root
buffer is required. The protective buffer shall consist of a base course of tree chips spread
over the root area to a minimum of 6-inch depth, layered by 3/4-inch quarry gravel to
stabilize 3/4-inch plywood on top. This buffer within the TPZ shall be maintained
throughout the entire construction process.
DAMAGE TO TREES
A.Reporting
Any damage or injury to trees shall be reported within 6-hours to the project arborist and
job superintendent or City Forester so that mitigation can take place. All mechanical or
chemical injury to branches,trunk or to over 2-inches in diameter shall be reported in the
monthly inspection notes: In the event of injury,the following mitigation and damage
control measures shall apply:
1. Root injury: If trenches are cut and tree roots 2-inches or larger are encountered they
must be cleanly cut back to a sound wood lateral root. The end of the root shall be
Page 6 of 9
C:\Documents and Settings\bcerda\Local Settings\Temporary Internet Files\Content.Outlook'XP9PXMEX\Construction preservation procedure.doe
covered with either a plastic bag and secured with tape or rubber band, or be coated with
latex paint. All exposed root areas within the TPZ shall be backfilled or covered within
one hour. Exposed roots may be kept from drying out by temporarily covering the roots
and draping layered burlap or carpeting over the upper 3-feet of trench walls. The
materials must be kept wet until backfilled to reduce evaporation from the trench walls.
2. Bark or trunk wounding: Current bark tracing and treatment methods shall be
performed by a qualified tree care specialist within two days.
3. Scaffold branch or leaf canopy injury: Remove broken or torn branches back to an
appropriate branch capable of resuming terminal growth within five days. If leaves are
heat scorched from equipment exhaust pipes, consult the project arborist within 6 hours.
The project arborist retained by the applicant shall conduct the following required
inspections of construction sites containing protected and designated trees. Inspections
shall verify that the type of tree protection is consistent with the standards outlined within
this guideline and Conditions of Approval for discretionary projects. For each required
inspection or meeting, a written summary of the changing tree related conditions, actions
taken, and condition of trees shall be provided to the City of Eagle. Monthly Inspection
Reports shall be faxed to the City Forester at (208)938-3854.
PAVEMENT AND HARDSCAPE CONFLICTSWITHTREE ROOTS
Conflicts may occur when tree roots grow adjacent to paving, foundations, sidewalks or
curbs (hardscape). Improper or careless extraction of these elements can cause severe
injury to the roots and instability or even death of the trees. The following alternatives
must first be considered before root pruning within the TPZ of a Regulated Tree.
INSPECTION SCHEDULE

TREE PROTECTION AND PRESERVATION REPORT
All protected or designated trees to be retained on a development site shall be shown on
approved sets of civil, building and landscape plans and shall be protected during the
construction process.A Tree Protection and Preservation Plan submitted for review by
the Planning and Zoning Department is required. The tree preservation plan shall assume
compliance with standards outlined in this guideline. In addition, the following submittal
information must be included in the report:
A. Scope& Construction Phasing
The Tree Protection and Preservation Plan shall identify, but not be limited to,written
recommendations for the health and long-term welfare of trees that are to be followed
during the following distinct phases and conditions: preconstruction; during construction,
post construction,demolition activities; methods of avoiding injury, damage treatment
and inspections. Schedules shall be included.
B.Tree Protection Zone
The Tree Protection and Preservation Plan shall establish a tree protection zone (TPZ)
for each tree to be fenced and clearly outline site-specific measures for protection of the
trees during construction and describe a plan for continued maintenance of those trees
after construction. After project approval, any changes to the protection measures must be
approved in writing, by the City Forester. The tree protection plan shall include the
following site plan elements:
SITE PLAN
A.Disclosure of all trees on and near the site
The property owner or designee shall provide accurate information to the project arborist
to develop the tree protection measures and to enable accurate recommendations to insure
their survival. This site plan shall accurately show the surveyed location, species, size of
trunk and leaf canopy; show the dripline of any neighboring trees that may overhang the
site and street trees that are within 30-feet on each side of the project. Failure to show a
tree on the plans and later determined to be affected by construction may require the
work to stop until mitigation can be agreed upon by the property owner and the City.
B.Plans submitted to the City
In addition to the above information, final improvement plans shall include and show the
following information: show the tree protection zone of any tree to be retained and denote
a 5-foot chain link type fencing around the protected zone of each tree or group of trees
(to be clearly identified as such on all plans as a bold-dashed line); permeable paving
located within the dripline area; approved utility pathways; grade changes; surface and
subsurface drainage and aeration systems to be used; walls,tree wells, retaining walls and
grade change barriers, both temporary and permanent; landscaping and irrigation within
dripline of trees.
C.Plans must show tree protection
Protective tree fencing identified within the arborist report, both written and
diagrammatic, shall be clearly shown as a bold, dashed line on the approved site plans
