What We Asked
02 | Engagement Report Back
Q1: What key tree regulation issues are the most important to you?
(n=772)
Benefits or incentives for retaining existing trees.
Ensure tree permit rules apply consistently across all types of projects.
Clear and objective standards for residential development.
Define who is responsible for taking care of street trees in the public ROW.
Require replacement trees that can grow to be large whenever possible.
Create clear rules for increasing the amount of tree canopy in commercial and industrial areas.
Make more types of tree removal permits include requirements to plant replacement trees.
Update tree rules to support wildfire-safe landscaping.
Set soil standards for street and parking lot trees so they stay healthy and have room to grow.
Improve the appeals process so it’s faster and less confusing.
Develop more efficient permit process for public agencies/utilities to manage trees.
Find solutions to balance trees with solar panels and other sustainable practices.

Q2. What are your biggest concerns about Lake Oswego's Urban Forest?
○Safety and Hazard Risk: Large old trees falling in storms.
○Developer Removals: Developers can easily removal a massive number of trees for
projects, fairly easily, and can use subdivisions to remove even more.
○Homeowner Regulatory Burden: Permit process is too restrictive, expensive, and time
consuming for the average property owner.
○Inadequate Mitigation and Replacement: Replacement requirements are seen as
inefficient and the dogwood problem is not ensuring long term integrity.
○Wildfire Risk and Prevention: Current code doesn’t support wildfire-safe landscaping.
○Invasive Species and Forest Health: Ivy and EAB are top concerns.
○Lack of City Maintenance (Public Trees): City isn’t leading by example in maintaining
trees in the ROW.
○Climate Change and Drought: More climate resilient, drought tolerant species and
natives are needed.
“Developers who
work around the
rules by lot
subdivision”.

03 Code Concepts
Update and Wrap Up
Discussion
●Concept Overview
●Report Back: PC and Council Feedback
●Discussion and Questions/Clarification
Creating clear and
objective standards
for residential
development
Concept 1 of 4
●Applicants choose between options to
retain a minimum of:
1.Percentage (50% or TBD) total trees
over 15” DBH or
2.Percentage (33% or TBD) total DBH
preservation over 6” DBH
Code Concept
03 | Code Concept Update
1. Creating clear and objective standards for residential development
●Exemptions for trees within the building
envelope for:
1.Small lots only (5000 SF or less) or
2.Lots that are no larger than 15% (or
TBD) of the minimum lot size
required in that zone.
●Alternatives analysis not needed,
can go straight to the percentage of
trees or DBH to determine if
removal is ok.
●Exemptions for dead, dying, hazard,
and nuisance trees.
●Bonus credits for high value native
trees (e.g. Oregon white oak, Pacific
madrone, Douglas-fir, bigleaf maple,
and western redcedar etc.)
(no change)
Concept Overview
03 | Code Concept Update
Which option do you prefer for clear and objective tree
retention standards?
●Retain a minimum % of total DBH over 6” DBH
●Retain a minimum % of total trees over 15” DBH
●Allow both
●Only small lots (≤ 5,000 SF)
●Small and modestly sized lots (no larger than 15%
of the minimum lot size required in that zone)
●All lots (no size limit)
●Yes
●No
●Need criteria defined first
Should exemptions for trees within the building envelope
apply to:
Should bonus retention credits be provided for
preserving high-value native trees (e.g., Oregon
white oak, Douglas-fir)?

Affordable housing exemptions
and/or incentives
●Suggestion: allow flexibility (lower
bar) of C/O preservation percentages
on lot for developers doing low
income housing.
●Risk: Reduction of tree canopy and
benefits of trees for low income
residents
●Existing conditions: There are
currently fee exemptions for
affordable housing.
Need more feedback on this slide pros/cons list from
Todd and others.
Or other mechanisms to incentivize affordable
housing through tree code or reduce barriers of the
tree code for affordable housing development.

●Applicants choose between
options to retain a minimum of:
1.Percentage (50% or TBD)
total trees over 15” DBH
and,
2.Percentage (33% or TBD)
total DBH preservation
over 6” DBH
Code Concept
●Peer cities: Look at what percentages they are using.
●Case Studies: How different percentages appear on
various lots.
●Comparative Past Projects: Look at recent projects
and compare how the existing code would compare to
various percentages of total trees and total DBH.

What information would be the most
helpful to consider when determining
an appropriate threshold for these
percentages?
●Peer cities: Look at what percentages they are using.
●Case Studies: How different percentages appear on
various lots.
●Comparative Past Projects: Look at recent projects
and compare how the existing code would compare to
various percentages of total trees and total DBH.
Lots ≤ 5000 sq. ft.
●25% of all residential and mixed use
zones that permit residential use
(4,065 total)
●15% of the residential zones that
have minimum lot size requirements.
R-3 high-density zone would be
impacted the most.

Discussion
Exemptions for trees within the building
envelope for small lots only (5000 SF or
less):
“Allowing trees to be removed within
building envelopes on smaller lots
recognizes the challenges of retaining
trees where there are space constraints.”

4. Consistency between development and non-development tree
permitting
For non-development Type II permits, applicants are given a path
to permitting removal of moderate-risk trees, even if removal will
have a significant negative impact on the character or aesthetics
of the neighborhood, if a:
(1) Tree Risk Assessment Qualified arborist to classify tree with a
“moderate” overall risk rating…. AND
(2) Arborist
determines there
are no alternatives
to reducing risk
rating to low;
(2) Arborist determines
demonstrable history
of similar tree failure in
the immediate area.

Should non-housing development
applicants be allowed to remove
moderate-risk trees when:
-A qualified arborist determines the
tree is moderate risk,
-And there are no feasible
mitigation options,
-And there’s a history of similar
failures nearby?
●Yes
●No
