SECTION IV. APPLICABLE REVIEW CRITERIA AND FINDINGS
18.790 Urban Forestry Plan:
18.790.030 Urban Forestry Plan Requirements
A. Urban forestry plan requirements.An urban forestry plan shall:
1. Be coordinated and approved by a landscape architect(the project landscape architect) or a
person that is both a certified arborist and tree risk assessor(the project arborist),except for
minor land partitions that can demonstrate compliance with effective tree canopy cover and
soil volume requirements by planting street trees in open soil volumes only;
A revised Urban Forestry Plan that was coordinated and approved by a certified arborist and tree risk
assessor(the project arborist) has been submitted.This standard is met.
2. Meet the tree preservation and removal site plan standards in the Urban Forestry Manual
(UFM);
A revised tree preservation and removal site plan (Sheet 6) that meets the standards set forth in the Urban
Forestry Manual has been submitted.This standard is met.
3. Meet the tree canopy site plan standards in the Urban Forestry Manual;and
A revised tree canopy site plan (Sheet 15) that meets the standards set forth in the Urban Forestry Manual
has been submitted. In addition, the project arborist has included a signature of approval and statement
attesting that the revised tree canopy site plan meets all of the requirements in Section 10, Part 2 of the
Urban Forestry Manual.This standard is met.
4. Meet the supplemental report standards in the Urban Forestry Manual.
A revised supplemental report wasrepared and submitted by the project arborist, Brandt D. Thissell of
AKS Engineering & Forestry, LLC This report indudes the required inventory data for existing open
grown trees, as outlined in Section 10, Part 3, Subsection D of the Urban Forestry Manual. The site is
zoned R-4.5;accordingly, the minimum required effective tree canopy for the entire site is 40 percent,and
15 percent per lot (Section 10, Part 3, Subsection M of the Urban Forestry Manual). Through the
supplemental report, the project arborist demonstrates how the effective tree canopy for the entire site
exceeds 40 percent,and meets 15 percent per lot This standard is met.
18.790.070 Modification to the Urban Forestry Plan Component of an Approved Land Use
Permit
C. Application procedures. Modifications to the urban forestry plan component of an
approved land use permit that are not exempted by subsection B of this section shall be
UFR2015-00003 Oak Street Estates Subdivision Urban Forestry Plan edification 2
processed as a Type I procedure, using approval criteria contained in subsection D of this
section.
The proposed modification to the Urban Forestry Plan Component of the approved Oak Street Estates
Subdivision (SUB2014-00001) does not meet any of the exemptions listed under subsection B;
therefore, this modification shall be processed as a Type I procedure using the following approval
criteria:
D. Approval criteria. The director shall approve the modification to the urban forestry plan
component of an approved land use permit upon determining:
1. The project arborist or landscape architect has provided a report and statement certifying
that the previously approved urban forestry plan did not account for the circumstances
that lead to the proposed modification;
The project arborist provided a report and statement (Written Narrative, dated June 8, 2015) certifying
that the previously approved Urban Forestry Plan did not account for the circumstances that lead to
the proposed modification. The applicant proposes to remove a 35-inch Oregon White Oak located on
Lot 9 (Tree No. 31142) that was originally planned for preservation. On June 23, 2015, the project
engineer submitted an addendum stating the project team encountered rocky soils during trench
excavation, thereby requiring the storm line to be wider and deeper than originally anticipated. The
applicant concludes that this tree removal is necessary to accommodate the revised storm drainage pipe.
In addition to the applicant's submitted materials, a city-contracted arborist conducted a site visit and
provided an assessment of Tree No. 31142. The city-contracted arborist's memorandum verifies that
the change in design for the storm drainage pipe will cause severe impacts to the tree's health and
stability,thereby necessitating its removal.This criterion is met.
2. The project arborist or landscape architect has provided a report and statement
certifying that there is no practicable alternative to the proposed modification; and
The project arborist provided a revised report and statement (dated June 8,2015) certifying that there is
no practicable alternative to the proposed modification. In addition, the city-contracted arborist's
memorandum confirms that there is no practicable alternative to the tree's removal, due to the site's
existing conditions, and the circumstances surrounding the storm drainage pipe's new design. This
criterion is met.
3. The project arborist or landscape architect demonstrates through a revised urban
forestry plan, compliance with Section 18.790.030.
The project arborist submitted a revised Urban Forestry Plan and supplemental report that demonstrate
compliance with Section 18.790.030,including tree preservation,protection and canopy standards. This
criterion is met.
FINDING: As demonstrated in the analysis above, the proposed modification to the Urban
Forestry Plan Component of the approved Oak Street Estates Subdivision (SUB2014-
00001) meets all applicable approval criteria,and can be approved.

CITY OF TIGARD
PLANNING/ENGINEERING
Lina and Mike,
In order to expedite this decision, I am going to respond with a brief email rather than preparing a memo.
AKS Engineering has requested a Type I Modification to the Urban Forestry Plan Component of the Oak Street Estatea
Subdivision to remove tree 31142, a 35-inch DBH Oregon white oak (Quercus garrayana).The reason for the requested
modification is unanticipated changes to the stormline excavation due to the presence of rocky soils. Below are my
finding for the Type I Modification approval criteria:
1.The project arborist or landscape architect has provided a report and statement certifying that the previously
approved urban forestry plan did not account for the circumstances that lead to the proposed modification;
The project arborist provided a report dated June 8, 2015 which did not clearly explain what conditions have changed
that lead to the modification. The project engineer subsequently produced an addendum to the report dated June 23,
2015 stating that due to the presence of rocky soils, excavation for the stormline is required to be wider and deeper than
typically required. Based on my field visit with City inspector, Mike White, the excavation will be within four feet of the
face of trunk of tree 31142. Typical minimum setback requirements for trees range from six times the tree diameter to
three times the tree diameter. This would equate to 17.5 feet to 8.75 feet for the subject tree. The setback for the
excavation would be less than four feet from the tree, which would cause severe impacts to the tree's health and
stability.
2.The project arborist or landscape architect has provided a report and statement certifying that there is no practicable
alternative to the proposed modification; and
The project arborist indicated in his June 8, 2015 report that relocating the storm line to retain the tree is not a
practicable alternative. I discussed with the City the alternative of relocating the stormline underneath the staircase or
pathway to retain the tree. This option would require an additional manhole, which the City's Public Works staff has
determined is not a practicable alternative due to maintenance difficulties on the steep slope. Therefore, it does not
appear that there are any practicable alternatives to relocating the stormline to avoid impacting the tree.
3.The project arborist or landscape architect demonstrates through a revised urban forestry plan, compliance with
Section 18.790.030.
The June 8, 2015 report includes a revised urban forestry plan that demonstrates compliance with Section 18.790.030.
Do not hesitate to contact me with any questions or concerns.

RE: Oak Street Estates—Tree#31142 Removal, Change of Conditions
Ms.Smith:
The purpose of this letter is to address a change of conditions associated with the trench excavation near
tree#31142,a 35" Oregon white oak.The tree sits adjacent to a proposed storm sewer line which is to be
constructed with the Oak Street Estates project. During the trench excavation, rocky soils have been
encountered, which causes the trench excavation to be wider and closer to the tree than originally planned.
This excavation will encroach too far into the trees root zone for the tree to be stable and healthy after
construction. We recommend that the tree be removed at this time. If you have any questions or
comments, please contact me at(503)563-6151 or alex@aks-eng.com.

RE: Oak Street Estates(SUB2014-00001)— Urban Forestry Plan Modification
Mr. Pagenstecher:
The purpose of this application is to modify the approved urban forestry plan for the above referenced project.
18.790.70 Modification to the Urban Forestry Plan Component of an Approved Land Use Permit
A. General provisions. Except as exempted in subsection B of this section, a modification to the urban
forestry plan component of an approved land use permit shall be processed as a Type I land use decision
as described below.
C. Application procedures. Modifications to the urban forestry plan component of an approved land use
permit that are not exempted by subsection B of this section shall be processed as a Type I procedure,
using approval criteria contained in subsection D of this section.
Response: The applicant is proposing to remove tree#31142, which was originally proposed for preservation
in the project's approved urban forestry plan. Construction of an adjacent public storm drainage pipe will
result in significant impacts to the tree's root zone, necessitating its removal. This modification is not
exempted by subsection B of this section;therefore,this modification is required to be processed as a Type
procedure using the approval criteria contained in subsection D(addressed below). This application includes
a completed Minor Modification—Type I Application form and supporting documentation.
D. Approval criteria. The director shall approve the modification to the urban forestry plan component of an
approved land use permit upon determining.
1. The project arborist or landscape architect has provided a report and statement certifying that the
previously approved urban forestry plan did not account for the circumstances that lead to the proposed
modification;
Response: The design of the public storm drainage pipe adjacent to tree#31142 was modified during
the final engineering and construction permitting phases of the project. The modified storm pipe design
will result in significant impacts to the root zone of the tree,necessitating its removal. The approved
urban forestry plan prepared and approved during the planning phase of the project did not account for
the modified storm pipe design. The standards of this section have been met.
2. The project arborist or landscape architect has provided a report and statement certifying that there is no
practicable alternative to the proposed modification;and
Response: The proposed storm pipe is located adjacent to a proposed concrete walkway and staircase.
Relocating the storm pipe a sufficient distance to the west to preserve tree#31142 is not a practicable
alternative as the storm pipe would conflict with the walkway and staircase. Additionally,these
features(storm pipe,walkway,and staircase)pass through a tree grove. Modifying the locations of
these features to preserve tree#31142 would necessitate the removal of several other trees,which is not
a practicable alternative. The standards of this section have been met.
3. The project arborist or landscape architect demonstrates through a revised urban forestry plan,
compliance with Section 18.790.030.
Response: Included with this application is a revised urban forestry plan(tree preservation and
removal plan,tree canopy plan,and supplemental arborist report)that demonstrates compliance with
Section 18.790.030. The standards of this section have been met.

Project Summary
This is a 38 lot residential subdivision project located in the R-4.5 Medium Density Residential
District requiring an effective tree canopy cover of 40%. Ninety trees are being preserved (14 trees
of which are in poor condition and are not included in the qualifying existing mature canopy per the
Urban Forestry Manual),and 86 trees are being planted. The net developed site area is 317,175
square feet +/-. Forty percent of that area equals 126,870 square feet +/-. The site will have a total
qualifying mature tree canopy area of 246,998 square feet,which is above the required 40% for this
zone. Therefore, since the effective canopy area of the existing trees and trees to be planted is
greater than 40% of the total area,no additional tree canopy fee is required. In addition,each of the
38 lots individually meets the City's lot canopy coverage of 15%effective canopy. Since all of the
City's canopy requirements are met,no tree canopy fee is required.

Oak Street Estates - Urban Forestry Plan — REVISED Supplemental Arborist Report
Tree Preservation Specifications:
A. No changes shall be made to any aspect of the approved urban forestry plan without written
consent from the project arborist and city arborist.
B. Timeline for clearing,grading,and installation of tree protection measures:Tree protection
fence shall be installed prior to any ground disturbance work.
C. Placing materials near trees: No person may conduct any activity within the protected area of
any tree designated to remain,including,but not limited to,parking equipment,placing
solvents,storing building material and soil deposits,dumping concrete washout and locating
burn holes.
D. Attachments to trees during construction: No person shall attach any object to any tree
designated for preservation.
E. Protective barrier. Prior to any ground disturbance by the contractor:
1. Shall erect and maintain readily visible tree protection fencing along the outer edge and
completely surrounding the protected area of all protected trees or groups of trees as shown.
Fences shall be constructed of 5 foot tall metal,secured to eight foot tall metal posts.Posts
shall not be placed further than 8 feet o.c. Apart.
2. May be required to cover with mulch to a depth of at least six (6) inches,or with plywood or
similar material,over the root zone of a tree in order to protect roots from damage caused
by heavy equipment.
3. Shall prohibit excavation or compacting of earth or other potentially damaging activities
within the tree protection zone.
4. May be required to minimize root damage by excavation of a two (2) feet deep trench,at the
edge of the tree protection zone, to cleanly sever the roots of trees to be retained.
5. May be required to have corrective pruning performed on preserved trees in order to avoid
damage from machinery or building activity. May be required to maintain trees throughout
construction period by watering and fertilizing.
6. Shall maintain the tree protection fencing in place until the project arborist and city arborist
authorizes their removal.
7. Shall ensure that any landscaping done in the tree protection zone subsequent to the removal
of the barriers shall be accomplished with light machinery or hand labor. Use plant materials
with compatible water requirements to tree to be preserved and direct spray irrigation away
from trunks.
F. The grade shall not be elevated or reduced within the tree protection zone without the
project arborist's authorization.The project arborist may allow coverage of up to one half of
AKS Engineering & Forestry Page 2
Oak Street Estates - Urban Forestry Plan — REVISED Supplemental Arborist Report
the area of the tree's root zone with light soils (no clay) to the minimum depth necessary to
carry out grading or landscaping plans,if it will not imperil the survival of the tree.Aeration
devices may be required to ensure the tree's survival.
G. If the grade adjacent to a preserved tree is raised such that it could slough or erode into the
tree protection zone,it shall be permanently stabilized to prevent suffocation of the roots.
H. An impervious surface shall not be installed within the tree protection zone of any tree to be
preserved without the authorization of the project arborist. The project arborist may require
specific construction methods and/or use of aeration devices to ensure the tree's survival
and to minimize the potential for root induced damage to the impervious surface.
I. To the greatest extent practical,utility trenches shall be located outside of the tree protection
zone of trees to be preserved. The project arborist may require that utilities be tunneled
under the roots of trees to be preserved if the project arborist determines that trenching
would significantly reduce the chances of the trees survival.
J. Directional felling of trees shall be used to avoid damage to trees designated for
preservation.
K. The project arborist may require additional tree preservation measures which are consistent
with tree care industry standards.
Root protection zone notes:
Encroachment into the root protection zone may be allowed with project arborist approval as
described in the following notes:
1. Excavation in the top 24" of the soil in the critical root zone area should begin at the excavation
line that is closest to the tree.
2. The excavation should be done by hand/shovel or with a backhoe and a man with a shovel,
pruning shears,and a pruning saw.
3. If done by hand,all roots 1" or larger should by pruned at the excavation line.
4. If done with a backhoe (most likely scenario),then the operator shall start the cut at the
excavation line and carefully"feel" for roots/resistance.When there is resistance, the man with
the shovel hand digs around the roots and prunes the roots larger than 1" diameter.
Stand Preservation Specifications:
No existing stand trees. Not applicable to this project.
Soil Characteristics and Specifications for Improvement:
Areas of Tree Growth Limiting Soils:
There are no known areas of tree growth limiting soils identified. If soil compaction
occurs,backhoe turning should be used to loosen soil. Remove any layers of good
topsoil. Spread 3"-4" of organics (high-lignin) compost or ESCS (Expanded
shale/Calcine Clay) amendment over the area prior to turning the soil. Maintaining a safe
distance from paving,sidewalks,and structures,use backhoe to turn soil to 36"
AKS Engineering & Forestry Page 3
Oak Street Estates - Urban Forestry Plan — REVISED Supplemental Arborist Report
depth. Break soil and loosely incorporate the soil amendment. Maintain a slope of
compacted soil at the edge of the paving so as not to undermine the paving sub-
base. Hand turning may be necessary along the edges of paving and at walls. Do not till
to a depth greater than the bottom of footing. After turning,re-spread topsoil and add
3"-5" of yard waste organic amendment over the surface and lightly till to break the soil
into texture suitable to fine grade.
Removal.Storing.and Amended Soils for Planter Areas:
Contractor shall removal all debris from planter areas and excavate to a depth of 36
inches. Slope sides of excavations at 1:1 slope or shore edges to prevent undermining of
vehicle load areas and to provide a sloped profile transition between soil types and
structural fill. Dispose of debris and subsoil. Stockpile excavated topsoil in approved
area off site.
Existing and imported topsoil amendments shall be determined by the Landscape
Architect and approved by the City Arborist. Soil mixing shall be done in designated
areas or in the supplier's yard. Mix amendments with topsoil when soil is in a friable
condition only(damp and not muddy with adequate moisture to break into clods when
turned and will not leave a mud stain on the hand when squeezed). Contractor to provide
certificate of content and percent of soil mixes with all amended soil to the City prior to
installation.
Blended Soil Placement and Compaction:
Soil shall be friable when placed and compacted. Place soil in layers of not more than 12"
in depth. Provide 3 passes with a 2"compact plate vibrating compactor. Compact to 80-
85%maximum dry density as measured by the proctor test or as approved for specific
blended soil mixes.
Tree Planting Specifications: Tree plantings shall conform to the City of Tigard design standards
and to American Nursery Standards ASN 1260.1. Plant in accordance with standards adopted by
the Oregon Landscape Contractors Board (OLCB). Trees to be planted shall meet the requirements
of the American Association of Nurserymen (AAN) for nursery stock (ANSI Z60.2) for Grade No.
1 or better. Double stake all trees. Root barrier shall be used on all trees adjacent to sidewalks,
roads,curbs,utility boxes,and other hardscape per the City of Tigard's Urban Forestry Manual
Section 2,Part 1.G.
Stand Planting Specifications:
No proposed stand trees. Not applicable to this project.

Tree Canopy Fee Calculation (if applicable)
If the percentage of effective tree canopy cover is less than the applicable standard percentage for
the overall development:
1. Find the required ft2 of tree canopy: 317,175 sf* 40%= 126,870 sf
(overall development site area) x (standard required% (40%,33%,o r25%)).
2. Find the ft2 of tree canopy the development is short: 126,870—246,998= -120,128; therefore
it meets the site canopy requirement.
(required ft2 of tree canopy from 1 above) - (proposed ft2 of tree canopy).
3. Find the $value of tree canopy: NA
(PNW-ISA wholesale median cost for a 3" deciduous tree in the Willamette Valley) _ 59.
4. Find the required tree canopy fee: NA
(amount of ft2 of tree canopy from 2 above) x (the$value of tree canopy from 3 above).
If the overall development meets the applicable standard percentage,but the percentage of effective
tree canopy cover is less than 15% for any individual lot or tract:
1. Find the required ft2 of tree canopy for deficient lot or tract: N/A
(lot or tract area) x 15%. All lots have at least 15%tree canopy cover.
2. Find the ft2 of tree canopy the lot or tract is short: NA
(required ft2 of tree canopy from 1 above) - (proposed ft2 of tree canopy).
3. Find the$value of tree canopy: NA
(PNW-ISA wholesale median cost for a 3" deciduous tree in the Willamette Valley) _ 59.
4. Find the required tree canopy fee: NA
(amount of ft2 of tree canopy from 2 above) x (the$value of tree canopy from 3 above).
Signature of Approval
I hereby attest that:
1. The Tree Preservation and Removal site plan meets all of the requirements in Section 10,
Part 1 of the Urban Forestry Manual;
2. The Tree Canopy site plan meets all of the requirements in Section 10, Part 2 of the Urban
Forestry Manual;and
