MEMORANDUM
CITY OF TIGARD, OREGON
TO: Tree Task Force
FROM: Dick B. and Carol L.
DATE: April 17, 1995
SUBJECT: Revised tree ordinance
Based on the group's comments at its last meeting, the following
changes were made to the draft ordinance:
1. 18. 150.010 - added # 8 to regulate commercial forestry
2. . 18 . 150.020 - added definition of commercial forestry (10 trees
per year per acre for sale)
3 . 18. 150. 025 - changed registered arborist to certified
arborist; Tog ain certification an arborist must meet
experience, schooling and test requirements. Urban forester
is a title used in some cities and does not necessarily mean
that person is certified.
4 . 18. 150.025 - added a range of mitigation based on the amount
of tree removal; This still may be a burdensome requirement.
5. 18. 150. 030 - added the word "only' relative to sensitive lands
and tree permits;
- added a provision to prohibit commercial forestry as defined
by this code; The State Forest Practices Act does not limit
the amount of harvest and relates primarily to water quality,
fish and wildlife. Referencing the State Forest Practices Act
as the standard does not work for urban areas according to
State Forest Practice Act administrators. The State will
provide consulting services but does not want to review
commercial forest removal inside cities and we would,
therefore, not be able to require state sign off on review of
applications. City staff is not equipped to administer the
Forest Practices Act, much of what is irrelevant to urban
areas. Wildlife/fish issues are goal five related and staff
believes venturing into this area would create difficulty and
delay adoption of tree removal requirements.
6. 18. 150.040 - changed the distance from a stream or wetland to
50 feet; There are two ways to look at this change. There
could be some concern that this added distance will unduly
complicate the development process, require more permits and
administration costs as well as potentially lower urban
density. On the other hand, 50 feet could be considered more
appropriate because greater density increases the threat of
damage to wetlands.
7. 18.150.045 - Attached is a memo from the City Attorney's
office indicating there would be no cloud on the title due to
the original wording of this section. To ease concern,
however, an attempt has been made to further clarify that the
deed restriction state that trees retained under the incentive
section may be removed only if a tree dies or is hazardous and
that the deed restriction may be removed or will be considered
invalid if such a tree is removed because it died or was
removed as a hazardous tree.

Memo re: Tigard Proposed Ordinance Section 18.150 - Tree Removal
Apldl 10, 1995 -
Page 2
A tree removal permit shall not be required for the removal of a
tree which:
1. Interferes with, or prevents safe access to,underground or overhead utility
lines;
2. Obstruct visual clearance as defined in Chapter 18.102 of the Code; .
+ 3. Is a dead or hazardous tree;
4. Is a nuisance affecting public safety as defined in Chapter 7.40 of the
Code;
It is apparent from the foregoing that both Sections 18.150.045,B and 18.150.030.B permit
removal of dead or hazardous trees or other trees which interfere, obstruct or constitute a
nuisance as set forth above. Under the circumstance, this would appear to be a reasonable and
valid restriction, not m the class of restrictions prohibited by ORS 93.270 (dealing with
dxscnminatory restrictions in conveyancing instrwments) and as such is a valid and appropriate
exercise of the authority of the City of Tigard.
As indicated above, marketable dile can clearly be conveyed subject to the dead restriction.
Therefore, there is no "cload" on title in the ordinary usage of that tem. However, the
recording of a deed restriction would place all parties on constructive notice that removal of
trees can only be accomplished without a permit in accordance with provisions of Section
18.150.030.B.1 through 18.150.030.8.4.
The effect of this restriction on marketability or resale value of a property cannot be foreseen
with complete accuracy. However, the ordinanaes cited clearly _mecMDicros for
removal of trees both with and without a permit- Any reasonable interpretation of the proposed
Ordinances establishes that a property owner could remove trees which would become a hazard
or a nuisance, even if such a tree was one originally "preserved" for the purpose of qualifying
for the incentives specified in Section 18.150.045.A of the ordinances. Accordingly, it is
anticipated that the impact on marketability of lots receiving incentives would be minimal-
I hope this satisfies your concerns regarding the proposed ordinance. Should you have any
questions regarding the foregoing, please do not hesitate to call-

provided by existing trees over twelve inches in caliper
EXHIBIT "A" TO ORDINANCE No. 94-
Page 4
that are preserved and incorporated into a development
plan, a one percent (1%) bonus may be applied to density
computations of Chapter 18.92. No more than a twenty
percent (20%) bonus may be granted for any one

applied to the number of dwelling units allowed in the
underlying zone.
2 . Lot Size Averaging. In order to retain existing trees
over twelve inches in caliper in the development plan for
any land division under Chapter 18. 160, lot size may be
averaged to allow lots less than the minimum lot size
allowed by the underlying zone as long as the average lot
area for all lots and private open space is not less than
that allowed by the underlying zone. No lot area shall
be less than eighty percent (80%) of the minimum lot size
allowed in the zone.
3 . Lot Width and Depth. In order to retain existing trees

percent (2%) of canopy cover provided by existing trees
over twelve inches in caliper that are preserved and
incorporated into a development plan for commercial,
industrial or civic uses listed in Section 18. 106.030,
Minimum Off-Street Parking Requirements, a one percent
(1%) reduction in the amount of required parking may be
granted. No more than a twenty percent (20%) reduction
in the required amount of parking may be granted for any
one development.
5. Commercial Industrial Civic Use Landscaping. For each
/ /
two percent (2%) of canopy cover provided by existing
trees over twelve inches in P
are caliper that reserved
P
and incorporated into a development plan, a one percent
(1%) reduction in the required amount of landscaping may
be granted. No more than twenty percent (20%) of the
required amount of landscaping may be reduced for any one
development.
6. Setback Adjustment. The Director may grant a
modification from applicable setback requirements of this
Code for the purpose of preserving a tree or trees on the
site of proposed development. Such modification may
reduce the required setback by up to 50%, but shall not
be more than is necessary for the preservation of trees
on the site. The setback modification described in this
section shall supersede any special setback requirements
or exceptions set out elsewhere in this Code, including
EXHIBIT "A" TO ORDINANCE No. 94-
Page 5
but not limited to Chapters 18.96, 18. 146, and 18 . 148,

tree plan according to Section 18. 150.025, and shall not be
subject to removal under any other section of this Chapter.
The property owner shall record a deed restriction that such
tree may be removed only if the tree dies or is hazardous
according to a certified arborist to this effect as a
condition of approval of any development permit impacted by
this section. The deed restriction may be removed or will
considered invalid if a tree preserved in accordance with this
section should either die or be removed as a hazardous tree. )
The form of this deed restriction shall be subject to approval
by the Director.

D. Replacement of a tree shall take place according to the
following guidelines:
1. A replacement tree shall be a substantially similar
species considering site characteristics.
2 . If a replacement tree of the species of the tree removed
or damaged is not reasonably available, the Director may
allow replacement with a different species of equivalent
natural resource value.
3 . If a replacement tree of the size cut is not reasonably
available on the local market or would not be viable, the
Director shall require replacement with more than one
tree in accordance with the following formula:
The number of replacement trees required shall be
determined by dividing the estimated caliper size of the
tree removed or damaged by the caliper size of the
largest reasonably available replacement trees. If this
number of trees cannot be viably located on the subject
property, the Director may require one or more
replacement trees to be planted on other property within
the City, either public property or, with the consent of
the owner, private property.
4. The planting of a replacement tree shall take place in a
manner reasonably calculated to allow growth to maturity.
