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 (Attachment D) 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 (Attachment E) 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 was prepared and submitted by the project arborist, Morgan Holen &
Associates,ILC.This report includes 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 exceeds 40 percent for the entire site, and 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
UIa2015-00004 Cokcicy Partition Urban I orestry Plan Modification 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 Cokeley Partition
(MLP2015-00004) 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 (Urban Forestry Plan Supplement Report, dated
September 7,2015) certifying that the previously approved Urban Forestry Plan did not account for the
circumstances that led to the proposed modification. The applicant proposes to remove one 28-inch
Douglas Fir and one 30-inch Douglas Fir located on Parcel 2 (which were originally planned for
preservation) in order to accommodate the construction of a new detached, single-family dwelling. In
addition, the applicant proposes to replace the two Douglas Firs with one 6-foot Western Redcedar and
one 1.5-inch Pacific Dogwood.
The arborist states, "The March 29, 2015 report was provided for a two-lot Minor Land Partition and
no construction was proposed at that time. This report was revised on September 7, 2015 based on the
proposed site plan for construction of a new single-family home" on Parcel 2. The arborist also adds,
"The previously approved Urban Forestry Plan did not account for the circumstances leading to the
proposed modifications...because a site plan for construction was not available."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 September 7, 2015) certifying that
there is no practicable alternative to removing the two Douglas Firs. The arborist states, "These trees
are located within the proposed building footprint for new home construction and protection is not
possible. There is no practicable alternative to the proposed modifications because these trees are
situated within the allowable building footprint" for Parcel 2. 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 Cokeley Partition (MLP2015-00004) meets
all applicable approval criteria,and can be approved.

Urban Forestry Plan - Supplemental Report
2-Lot Partition
6617 SW Walnut Terrace, Tigard, Oregon
March 29, 2015
Revised: September 7, 2015
M HA15021
Purpose
This Urban Forestry Plan for the two lot partition located in an R-4.5 zoning district at 6617 SW Walnut
Terrace in Tigard, Oregon, is provided pursuant to the City of Tigard Urban Forestry Manual. This report
describes the existing trees located on the project site, provides arborist recommendations for tree
preservation and planting, and describes the effective tree canopy cover needed to meet City
requirements.This report is based on observations made by International Society of Arboriculture (ISA)
Certified Arborist and Qualified Tree Risk Assessor Morgan Holen (PN-6145A) during a site visit
conducted on March 23, 2015.
The March 29, 2015 report was provided for a two-lot minor land partition and no construction was
proposed at that time. This report was revised on September 7, 2015 based on the proposed site plan
for construction of a new single-family home on vacant lot 2. Two trees originally planned for retention
on lot 2 are now recommended for removal for the purposes of construction and two new trees are
proposed to be planted on lot 2;tree protection specifications have also been added. Modifications to
an existing tree plan require a Type I land use decision. This revised Urban Forestry Plan demonstrates
compliance with Section 18.790.030 of the code and satisfies the approval criteria of Section
18.790.070.D.
General Description
The site is located along the north side of SW Walnut Terrace and includes one existing single family
residential home near the street and five on-site trees scattered in the rear yard to the north. A two lot
partition is proposed, with lot 1 encompassing the existing home in the southern portion of the site and
lot 2 to the north including a 15-foot access strip bordering the west side of lot 1. A new home will be
built on lot 2 with a driveway and utilities.
The existing on-site trees include one mature Oregon white oak(Quercus garryana) on lot 1 and two
mature Douglas-firs (Pseudotsuga menziesii) and one relatively young ornamental cherry(Prunus spp.)
on lot 2. These trees are all in generally good condition. One black walnut (Juglans nigra)with poor
structure and substantial dieback is also located on lot 2. The Oregon white oak on lot 1 is suitable for
preservation with special protection during lot 2 construction.The trees located on lot 2 are
recommended for removal either because of poor condition or for the purposes of construction.
In addition to the five on-site trees,four trees are located on adjacent properties within 25-feet of the
subject site. This includes a remarkable ponderosa pine (Pinus ponderosa) east of lot 1, a mature Oregon
white oak that is codominant in crown class with the on-site oak located on lot 1, and a Douglas-fir
bordering lot 2 to the west and a red maple (Acer rubrum) bordering lot 2 to the east, which are both in
good condition.

Walnut Terrace Partition,Tigard,Oregon
Page 2
A complete description of the nine individual trees inventoried on-and off-site is provided in the
enclosed existing tree inventory data (attachment A). With the proposed modifications to the Urban
Forestry Plan,treatment recommendations have been revised to account for the removal of trees 103
and 104 on lot 2.
The previously approved Urban Forestry Plan did not account for the circumstances leading to the
proposed modifications to remove trees 103 and 104 because a site plan for construction was not
available. These trees are located within the proposed building footprint for new home construction and
protection is not possible. There is no practicable alternative to the proposed modifications because
these trees are situated within the allowable building footprint for lot 2.
Effective Tree Canopy Cover
Of the five existing on-site trees, one tree recommended for preservation on lot 1 provides double
canopy cover credit to meet the City's effective tree canopy cover requirements.
Street trees are required to be planted in the right-of-way along SW Walnut Terrace. The required
number of street trees is based on the linear right-of-way frontage divided by 40. The total frontage is
85.97 linear feet;therefore,two street trees are required.The new street trees will be installed in a
vacant landscape island measuring approximately 33-feet long by 12-feet wide. Assuming a soil depth of
three feet,the total available soil volume is in excess of 1,000 cubic feet. Attachment B is the Planted
Tree Inventory describing the two trees proposed for planting, which are non-native and small statured
Eastern red buds (Cercis Canadensis). The proposed new street trees comply with the street tree planting
standards in Section 2 of the Urban Forestry Manual and with the soil volume standards in Section 12.
These trees also provide canopy cover credit to meet the City's effective tree canopy cover
requirements.
In addition, the Planted Tree Inventory was revised with the proposed modifications to the Urban
Forestry Plan to provide two new native trees on lot 2, including one large statured western redcedar
(Thuja plicata) and one medium statured pacific dogwood (Cornus nuttallii).
A summary of the effective tree canopy cover by lot and across the overall development site is included
as attachment C. Proposed lot 1 is 7,502 square feet and has 88.4% effective tree canopy cover and
proposed lot 2 is 10,151 square feet and has 17.4%effective tree canopy cover. The minimum required
effective tree canopy for lots 1 and 2 is 15%each; therefore, the effective tree canopy cover
requirement is met for each lot.
The overall development site is 17,653 square feet and has 47.6% effective tree canopy cover. The
minimum required effective tree canopy for the overall development site is 40%;therefore,the effective
tree canopy cover requirement for the overall development site is also met.
The Tree Preservation and Removal Site Plan and Tree Canopy Site Plan are enclosed as attachments D
and E as required by Section 10 of the Urban Forestry Manual, which illustrate how the Urban Forestry
Plan requirements are met. With the proposed modifications to the Urban Forestry Plan,the original
mark-ups prepared by Morgan Holen &Associates were revised and a new plan showing the proposed
construction on lot 2 was added for additional information.

Specifications
A. Tree Protection Specifications
1. Tree Protection Zone.The project arborist shall designate the Tree Protection Zone
(TPZ). Where feasible,the TPZ shall be established at the dripline of protected trees
as a minimum. If infrastructure must be installed closer to the trees,the TPZ may be
established within the dripline area if the project arborist determines that the trees
will not be unduly damaged. The location of the TPZ shall be shown on construction
drawings.
2. Protection Fencing.All trees to be retained shall be protected by orange plastic
construction fencing or other fencing as approved by the project arborist. Protection
fencing shall be secured to steel posts placed no further than 8-feet apart and shall
be installed at the edge of the TPZ.
3. Preconstruction Conference. The project arborist shall be on site to discuss methods
of tree removal and tree protection prior to any construction.
4. Pruning. The project arborist can help identify if and where pruning is necessary
once trees recommended for removal have been removed and the site is staked and
prepared for construction. Pruning shall be performed by a Qualified Tree Service.
5. Tree Protection Zone Maintenance.The protection fencing shall not be moved,
removed, or entered by equipment except under direction of the project arborist.
6. Storage of Material or Equipment.The contractor shall not store materials or
equipment within the TPZ.
7. Excavation. Excavation within the TPZ shall be avoided if alternatives are available. If
excavation within the TPZ in unavoidable,the project arborist shall evaluate the
proposed excavation to determine methods to minimize impacts to trees. All
construction within the TPZ shall be under the on-site technical supervision of the
project arborist.
8. Tree Protection Inspection.The project arborist shall inspect and verify the location
of protection measures prior to construction, monitor tree protection measures
regularly, and provide biweekly written reports to the City during periods of active
construction.
9. Final Report.After the project has been completed,the project arborist shall provide
a final report that describes the measures needed to maintain and protect the
remaining trees.
B. Soil Characteristics and Specifications for Improvement
Native soils at the project site are Cascade silt loam, which are relatively shallow and
somewhat poorly drained. Prior to street tree planting, excavate to a depth of 36-inches three
times the width of each rootball, and replace the excavated material with amended topsoil;
topsoil amendments should be determined by the landscape contractor at the time of
installation.
