AGENDA BILL
Monday, January 23, 2023
Subject: Tree Management Code Amendments
Category: City Business
Staff Contact: Steven R. Wilcox, Development Services Director
Summary
The purpose of this Agenda Bill is for Council to consider directing city staff to perform two tasks:
1. Prepare draft amendments to Medina Municipal Code Chapter 16.52 Tree Management Code
according to the six (6) “Short-term Solutions” as presented by our City Arborists.
2. Prepare a plan for an approach to a comprehensive review of MMC Code Chapter 16.52 Tree
Management Code.
In 2022 Medina employed two new arborist consultants, Sean Dugan (Tree Solutions, Inc.) and
Andy Crossett (Tree Frog, LLC). Following a consistent 15-years of success with our previous
consulting arborist Tom Early, our two new arborists have brought us a fresh perspective and
have voiced their observations regarding the effectiveness of our Tree Management Code while
considering the defined Purpose and Intent.
Ordinances adopted by municipalities require amendments from time to time. A discussion about
the effectiveness of our Tree Management Code is appropriate now that we have new information.
Presenting our arborist’s observations is important for Council to hear so that decisions about
possible actions can be made.
Sean Dugan is a Principal with Tree Solutions, Inc. Sean performs development project work for
Medina. Sean is involved with proposed development projects from pre-application through final
inspection approval. Sean primarily interacts with property developers and contractors. More
information about Sean and his company may be found at Tree Solutions Inc. - a tree consulting
company in the Pacific Northwest.
Andy Crossett is owner of Tree Frog LLC. Andy performs non-development work for Medina.
Any request by a Medina resident for tree removal, tree health assessment, and general tree
related code enforcement outside of new development projects including the public right of way,
are assigned to Andy. Andy primarily interacts with our residents and finds himself often guiding
people through our permit process. More information about Andy and his LLC may be found at
Tree Frog LLC.
The proposed project meets and supports Council priorities 3, 4, and 5.

PowerPoint presentation prepared by Sean Dugan and Andy Crossett
MMC Ch. 16.52 with our arborist’s and staff comments
Budget/Fiscal Impact:
1. Code amendment draft preparation estimated at $25,000. This is an estimated cost to draft
simple code amendments necessary to affect short-term solutions to matters involving the
Tree Management Code.
2. Comprehensive review plan draft estimated at $2,000 preparation. This is not the cost to
comprehensively review the entirety of the Tree Management Code.
Estimates are for consulting arborists and attorney’s costs. There is no defined budget for this
work.
Recommendation: Approve.
City Manager Approval:
Proposed Council Motions:
1. I move to direct city staff to prepare for Council consideration draft amendments to the Medina
Municipal Code Chapter 16.52 Tree Management Code according to the six (6) “Short-term
Solutions” bullet points as presented at the 1/23/23 meeting by our tree code consultants.
2. I move to direct city staff to prepare for Council consideration a plan for a comprehensive
review of the Medina Municipal Code Chapter 16.52 Tree Management Code.

Created: 2022-10-03 13:32:36 [EST]
(Supp. No. 4)
Page 1 of 25
16.52.010. Purpose and intent.
A. The purpose of the tree management code is to preserve the existing sylvan appearance through long-term
preservation and planting of trees that contribute to the community's distinct features including proximity to
the lakeshore, views, heavily landscaped streetscapes, and large tracts of public and private open spaces. The
city recognizes that trees:
1. Contribute to the residential character of the city;
2. Provide a public health benefit;
3. Provide wind protection, ecological benefits to wetlands and watercourses, and aid in the stabilization
of geologically hazardous areas;
4. Improve surface water quality and control and benefit Lake Washington; and
5. Reduce noise and air pollution.
B. The intent of this chapter is to establish regulations and standards that:
1. Protect and preserve the existing tree canopy;
2. Provide homeowners flexible standards that encourage the preservation of trees while recognizing the
importance of having access to sunlight and views;
3. Recognize through the standards in this chapter that certain factors may require the removal or
pruning of certain trees due to circumstances such as disease, danger of falling, proximity to structures
and improvements, interference with utility services, protection of view and sunlight, and the
reasonable enjoyment of property;
4. Encourage best practices for the planting and managing of trees appropriately to minimize hazards,
nuisances, and maintenance costs while allowing access to sunlight and views;
5. Prevent the indiscriminate removal or destruction of trees except as provided for in accordance with
this chapter;
6. Promote building and site planning practices consistent with the purpose and intent of this chapter;
7. Ensure prompt development, restoration, replanting and effective erosion control of property after
tree removal with landscape plans and other reasonable controls; and
8. Foster public education on the local urban forestry program and encourage good tree management
consistent with this chapter.
(Code 1988 § 20.52.010; Ord. No. 1012 , § 2, 7-11-2022; Ord. No. 923 § 9, 2015; Ord. No. 909 § 2 (Att. A), 2014)
16.52.020. General provisions and applicability.
Where land is designated as under development pursuant to MMC 16.52.090, the preservation of healthy
trees shall be considered in accordance with the following guidance:
1. Tree preservation shall be included as a primary step in site planning and shall be achieved by meeting
the minimum required tree units established in Table 16.52.090(B).
2. Site design strategies and specific development site areas demonstrating preservation of significant
trees shall be presented at the pre-application meeting with the city.
Commented [se1]: Purpose of review: What additional
can be addressed to ensure the preservation and protection
of trees, especially larger trees
Commented [se2]: The intent of the code discuses tree
canopy but the minimum standards focus on the number of
trees. Canopy retention and the number of retained trees is
not always a direct correlation when trying to address the
items identified within the purpose of the code.
Commented [se3]: This section of the code is a tool that
is used to help prevent the indiscriminate removal of trees
not associated with development.
Commented [se4]: Need more clarity and direction
regarding how the city arborist is to qualify the reasonable
enjoyment of property.
Commented [se5]: This requires the city arborist to be an
advocate for the code's intent.
Commented [se6]: Need to identify what specific sections
of the code the city arborist needs to reference to
document that a proposed tree removal is considered
indiscriminate.
Commented [se7]: City arborist will need to request and
suggest alternative construction methods. Reference to use
should include ISA BMP's for construction.
Commented [se8]: City arborist will need to work with
city's grading and drainage consultant. Suggested approach
should be to reach out following pre-app and before permit
approval.
Commented [se9]: How do we know that preservation of
the required minimum tree units is working to achieve the
codes purpose and intent? To be inline with the intent,
should there be an account of existing canopy, canopy
retained, and canopy removed?
Commented [se10]: This is not how the process always
goes. Often the applicant is presenting a significantly
developed plan set. The 2022 code revisions provides the
city arborist with better tools to address how development
can exist with trees.

3. A tree preservation plan shall be required that demonstrates the objectives outlined in MMC
16.52.170.
4. Any applicable grading plans, pursuant to MMC Chapter 16.43, shall be developed to avoid significant
alteration to the grades around preserved trees.
5. Multiple applications of the tree preservation requirements in this chapter over a ten-year period shall
not cause the number and size of trees required to be retained to be reduced below the number and
size of trees required to be retained with the first application.
6. When calculating tree preservation requirements, trees excluded from preservation requirements shall
not be included in the calculation.
7. For the purpose of calculating tree density requirements, critical areas and their associated buffers
shall be excluded from the lot area used for calculation (example: a 16,000 square foot lot has a stream
on site that encompasses 1,500 square feet including the stream buffer. The lot area used for tree
density calculation would be 14,500 square feet (16,000 - 1,500 = 14,500) provided:
a. Critical areas shall be limited to wetlands, streams, geologically hazardous areas, conservation
easements, and their associated buffers as described in MMC chapters 16.50 and 16.67; and
b. Removal of any vegetation or woody debris, including trees, from a critical area is subject to the
regulations in MMC chapters 16.50 and 16.67.
8. All of the following shall be excluded from the requirements of this chapter:
a. Hazard trees designated pursuant to MMC 16.52.120;
b. Nuisance trees designated pursuant to MMC 16.52.130 and where, if applicable, re-development
does not remedy the conditions causing the nuisance;
c. Those significant trees having less than a 24-inch diameter breast height size and located within
the footprint of the principal building on the lot.
(Ord. No. 1012 , § 2, 7-11-2022)
Editor's note(s)—Ord. No 1012 , § 2, adopted July, 11, 2022, amended the Code by adding a new § 16.52.020, and
renumbering former §§ 16.52.020—16.52.060 as §§ 16.52.030—16.52.070.
16.52.030. Applicability of the tree management code.
A. No person or their representative, directly or indirectly, shall remove or destroy trees located on private
property or public property within the jurisdictional boundaries of the city except as provided for in
accordance with this chapter.
B. Additional tree management requirements are set forth in the Medina shoreline master program as provided
in MMC 16.66.050.
(Code 1988 § 20.52.020; Ord. No. 1012 , § 2, 7-11-2022; Ord. No. 923 § 10, 2015; Ord. No. 909 § 2 (Att. A), 2014)
Note(s)—Former § 16.52.020. See editor's note, § 16.52.020.
16.52.040. Exemptions.
The following are exempt from the requirements in this chapter:
Commented [se11]: The language is still not 100% clear.
Does this mean just make sure minimum standards are
followed? Need to establish a tracking method to ensure
this requirement is met.
Commented [se12]: Per sections of code, exclude: non
approved species, hazard, nuisance, hedge trees, non-
healthy trees, trees <24" in the building envelope
Commented [se13]: This section is unclear if trees in the
critical area are included in the calculation. It only reads the
critical area and buffer. As I interpret this, while the critical
areas are excluded from the calculations the trees in the
critical areas are not excluded and can be used for tree
credits.
This is concerning in that there might be a 10,000 sq. ft. lot
with 2,000 sq feet of steep slope. Four trees on the slope
can achieve the minimum tree units for the entire lot.
The remaining 8,000 sq. ft. can be cleared.
If the trees on the slope are excluded, then there needs to
be at least 4 trees for the 8,000 sq. ft. portion of the lot.
Per Stephanie K: The intent was to exclude critical areas and
their buffers and not count those trees in the calculations.
The thought was that critical areas have their own section of
the code and you’re very limited with what you can remove
in that area period. We had a discussion in Planning
Commission similar to what you pointed out in that we
didn’t think the intent of the code was to allow someone
with a critical area on their property be able to clearcut
everything outside of the critical area.
Commented [se14]: Conflicts with 16.52.160.B.4.a; also
should be in exemption 16.52.040

A. Trees less than six inches diameter breast height unless the tree is used to satisfy a requirement of this
chapter;
B. Normal and routine trimming and pruning operations and maintenance of trees and vegetation on
private property following the most current ANSI standards;
C. Emergency tree removal or hazard pruning for any tree that poses an imminent threat to life or
property provided:
1. The city is notified within seven days after the emergency tree removal or hazard pruning takes
place and evidence is provided of the imminent threat supporting the emergency tree removal;
and
2. If evidence of the imminent threat is not provided, or the director determines the evidence does
not warrant an emergency tree removal, the director may require the responsible person to
obtain a permit as prescribed by this chapter and require compliance with the requirements of
this chapter;
D. Trimming and pruning operations and maintenance of trees and vegetation following the most current
ANSI standards or removal of trees performed by the city or a contractor contracted by the city within
a public right-of-way or city-owned parkland;
E. Removal of trees and vegetation management by the city or an agency under contract with the city for
purposes of installing and maintaining fire hydrants, water meters, pumping stations, or similar
utilities; or
F. The removal of a dead tree where the director pre-determines that the tree died from naturally
occurring causes.
(Code 1988 § 20.52.030; Ord. No. 1012 , § 2, 7-11-2022; Ord. No. 923 § 12, 2015; Ord. No. 909 § 2 (Att. A), 2014)
Note(s)—Former § 16.52.030. See editor's note, § 16.52.020.
16.52.050. Using this chapter.
This chapter prescribes the requirements for tree preservation and planting on lands undergoing
development, and the requirements for removal of significant trees on private and public lands. Diagram
16.52.050 offers a user's guide that outlines the general process for applying the provisions of this chapter.
Commented [se15]: There are no sections within the
code that outline violations or appeal process. Both are
common in tree code. Recommend clarifying violations
process.

Note(s)—Former § 16.52.040. See editor's note, § 16.52.020.
16.52.060. Designation of significant tree species.
A. A list of suitable tree species consisting of coniferous and deciduous trees is set forth in the document
entitled "City of Medina List of Suitable Tree Species," adopted by Ordinance No. 923 and on file with the city
for the purpose of establishing significant tree species on private property, public property, and city rights -of-
way; and tree species that are eligible for credits in this chapter.
B. The director shall maintain the "City of Medina List of Suitable Tree Species" document at Medina City Hall
and may administratively modify the list consistent with the following criteria:
1. The designation of coniferous trees should include all species excluding tree species known to have
invasive root structures and to be fast growing such as Leyland cypress and should also exclude trees
planted, clipped or sheared to be used as a hedge;
2. The designation of deciduous trees should include those suitable to United States Department of
Agriculture Plant Hardiness Zones 8 and 9, excluding those trees with crown diameter of ten feet or
less at maturity;
3. Plantings of the following tree species within the city's rights-of-way shall be prohibited: London plane,
quaking aspen, Lombardy poplar, bolleana poplar, cottonwood, and bigleaf maple.
C. The director shall submit proposals to modify the "City of Medina List of Suitable Tree Species" to the city
council for their consideration. The city council may approve, modify or deny the proposed modifications.

The city council may also decline to take action on the proposed modifications, in which case the
modifications shall be incorporated into the list and take effect five days after the date the city council
declines to take action.
D. The "City of Medina List of Suitable Tree Species" is used in conjunction with the definition of significant tree
set forth in MMC 16.12.200 to denote the term significant tree as used in this chapter.
(Code 1988 § 20.52.050; Ord. No. 1012 , § 2, 7-11-2022; Ord. No. 923 § 14, 2015; Ord. No. 909 § 2 (Att. A), 2014)
Note(s)—Former § 16.52.050. See editor's note, § 16.52.020.
16.52.070. Designation of land under development.
Land is designated as under development for purposes of this chapter if one or more of the following
conditions is present:
A. Any development activity requiring a building permit where:
1. Construction of a dwelling having a gross floor area of 2,500 square feet or more;
2. Construction of accessory buildings on property containing a residential use, or supporting a
residential use, where the total gross floor area of all accessory buildings on the lot is 1,000
square feet or more;
3. Any building constructed to be occupied principally by a nonresidential use where the gross floor
area of the building is 1,000 square feet or more;
4. Any series of exterior alterations, modifications or additions that over a four-consecutive-year
period increases the total building footprint on a lot by more than 500 square feet or 15 percent,
whichever is larger;
5. Construction of any structures, including but not limited to driveways, decks, patios, and
walkways, that over a four-consecutive-year period increases the impervious surface on the lot
by a total of 2,000 square feet or more;
6. Grading that over a four-consecutive-year period totals 2,000 cubic yards or more.
B. Any development activity requiring a building permit, a right-of-way permit, and/or a land use or
shoreline permit where:
1. One or more significant trees are removed, with at least one tree having a ten-inch diameter
breast height or larger size; or
2. Four or more significant trees are removed, provided each has less than a ten-inch diameter
breast height size; and
3. The criteria in subsections (B)(1) and (2) of this section shall include the following trees:
a. Significant trees removed within two years prior to the submittal of an application for such
permits; or
b. Significant trees removed within two years after such permits are finalized by the city and
the project completed.
C. Clearing or grubbing of land that:
1. Is located outside of city rights-of-way;
2. Requires no permits, except for a tree permit; and
Commented [se17]: Recommend updating list to allow
for some deciduous non-native trees that can attain a large
size to be supplemental trees.
The current list of native only deciduous trees is small, the
nursery stock is not always available at the required size,
the native trees are experiencing many biotic issues making
them poor choices to establish. The conditions the trees are
being planted in are not native.
Commented [se18]: Should there be a square footage
clearing component that would trigger a land to be under
development, such as clearing of 10K square feet?

3. Removes four or more significant trees, with at least four trees having a ten-inch diameter breast
height or larger size, over a four-consecutive-year period.
D. The counting of removed trees under subsections (B) and (C) of this section shall not include those
trees designated as a hazard or nuisance tree pursuant to MMC 16.52.120 and 16.52.130, respectively.

This section applies to trees designated as legacy and landmark trees, which are native trees that because of
their age, size and condition are recognized as having outstanding value in contributing to the character of the
community. Legacy and landmark trees within the shoreline jurisdiction are regulated in MMC 16.66.050.
A. A legacy or landmark tree shall be designated by meeting the following criteria:
1. Legacy tree:
a. The tree species is denoted as a legacy tree on the "City of Medina List of Suitable Tree
Species"; and
b. The diameter breast height of the tree is 36 inches or larger but less than 50 inches; and
c. The city arborist determines the tree to be healthy with a likelihood of surviving more than
ten years based on assumptions that:
i. The tree is properly cared for; and
ii. The risk of the tree declining or becoming a nuisance is unenhanced by any
proposed development.
2. Landmark tree:
a. The tree species is denoted as a legacy tree on the "City of Medina List of Suitable Tree
Species"; and
b. The diameter breast height of the tree is 50 inches or larger; and
c. The city arborist determines the tree to be healthy with a likelihood of surviving more than
ten years based on assumptions that:
i. The tree is properly cared for; and
ii. The risk of the tree declining or becoming a nuisance is unenhanced by any
proposed development.
B. Legacy and landmark trees shall be preserved and retained unless replacement trees are planted in
accordance with the following:
1. Legacy tree:
a. The quantity of replacement trees is calculated by multiplying the diameter breast height
of each subject legacy tree by the required percentage standards in Table 16.52.080(B) to
establish the number of replacement inches; and
Commented [se19]: Why not include not native trees?
Non-native would capture redwood, which has the potential
to achieve this size and is a great tree for the region.

Less than 10,001 10% removed DBH
From 10,001 to 13,000 15% removed DBH

From 15,001 to 20,000 35% removed DBH
Greater than 20,000 50% removed DBH
The following example illustrates how to calculate legacy tree replacement units on a lot that is less than 10,001
square feet:
Lot size: 8,120 square feet.
Required tree units: 8,120 / 1,000 x 0.4 (tree density ratio) = 3.2 (rounded up to the next whole number) = 4
Total existing tree units on site: 6.5 units
Eight 10-inch DBH trees - 4 units (.5 units per tree)
Two 24-inch DBH trees - 1.5 units (.75 units per tree)
One 44-inch DBH Tree - 1 unit (1 unit per tree)
Total tree units removed: 3
Four 10-inch DBH trees = 2 units removed
One 44-inch DBH tree = 1 unit removed
Net tree units: 3.5
Supplemental units required: Yes (4 required tree units - 3.5 net tree units) = .5 or 1 tree
Legacy tree removed: Yes - One 44-inch DHB tree
Legacy tree supplemental units: 10 percent x 44 = 4.4 (rounded up to the next whole number) = 5 legacy
replacement inches
Landmark tree removed: No
Total supplemental requirements = 1 tree plus 5 inches = 4 2-inch trees
2. Landmark tree:
a. The quantity of replacement inches is calculated by multiplying the diameter breast height
of each subject landmark tree by 100 percent to establish the minimum number of
replacement inches; and
b. All fractions of this section shall be rounded up to the next whole number.
C. In lieu of planting the replacement trees prescribed in subsection (B) of this section, an applicant may
satisfy the tree replacement requirements by meeting the criteria set forth in MMC 16.52.180.
D. Other provisions.
1. Each replacement tree shall meet the standards prescribed in MMC 16.52.090;
Commented [se20]: This section should reference where
the tree unit value is coming from for clarity.

2. The tree replacement requirements set forth in subsections (B) and (C) of this section shall apply
to the removal of legacy and landmark trees in lieu of and in addition to requirements for
removing nonlegacy trees;
3. The tree replacement requirements set forth in this section for a legacy and landmark tree shall
not be used to satisfy requirements for removing nonlegacy trees or a pre-existing tree unit gap;
4. If the minimum preservation standards in MMC 16.52.090 are used, and if supplemental tree
units are required, the tree replacement requirements set forth in subsections (B) and (C) of this
section shall together count as one supplemental tree unit;
5. Off-site tree planting as described in MMC 16.52.100 (C)(2) are acceptable alternatives to on-site
replacement tree planting provided the director or designee approves of the off-site location in
writing.

16.52.090. Minimum preservation standards for land under development.
A. The requirements and procedures set forth in this section shall apply to lands that are designated as under
development pursuant to MMC 16.52.070. Figure 16.52.090 outlines the primary steps prescribed by this
section in establishing requirements and determining compliance with this chapter.
B. Lots with land under development shall contain a sufficient number of significant trees to meet the minimum
required tree units established by the following procedures:
1. The lot area is divided by 1,000 square feet; and
Commented [an21]: Is this still applicable? Last time I
spoke to Tom, he said Medina didn't have any suitable off-
site locations for replanting.
Commented [se22]: The code is based on a tree unit
formula approach and using replacement trees to achieve
the minimum standards. Does this approach ahieve the
code's purpose and intent in regard to preserving and
protecting canopy? Is it measurable? Is it enforceable?
Commented [se23]: There is no method to address trees
that straddle the property line.

2. The quotient is multiplied by the corresponding tree density ratio applicable to the lot as set forth in
Table 16.52.090(B); and
3. The resulting product is rounded up to the next whole number to establish the minimum number of
required tree units.

C. To determine compliance with the required tree units applicable to the lot, apply the following procedures:
1. Inventory all existing significant trees on the subject lot; and
2. Assign a tree unit to each significant tree using the corresponding tree unit set forth in Table
16.52.090(C); and
3. Add the tree units together to compute the total existing tree units and subtract the tree units of those
significant trees removed to determine the net existing tree units (do not round fractions); and
4. Subtract the net existing tree units from the required tree units determined in this subsection (C) to
establish:
If the net existing tree units equal or exceed the required tree units then no supplemental trees
are required; or
If the net existing tree units are less than the required tree units then supplemental trees are
required pursuant to subsection (D) of this section.

Commented [se24]: This approach can still allow for a
substantial clearing of a site with little regard to canopy
cover or preservation/protection of canopy. Other
municipalities address this by allowing only a certain % of
the overall trees be removed or place annual limits on
removal, often tied to lot size. (ex. 1 tree/yr lots <10k feet;
2/yr 10k<20K;...

D. If supplemental trees are required, the quantity of trees is determined by applying the following procedures:
1. Determine if a pre-existing tree unit gap exists by subtracting the total existing tree units from the
required tree units:
If the difference is less than zero round to zero;
A difference of zero means no pre-existing tree unit gap is present;
If the difference is greater than zero, the difference is the pre-existing tree unit gap;
2. To calculate the quantity of supplemental trees required, apply the provisions in subsection (D)(3) of
this section first to those supplemental trees replacing an existing significant tree starting in order with
the largest tree to the smallest tree, and then, if applicable, apply subsection (D)(3) of this section to
those filling a pre-existing tree unit gap;
3. The quantity of supplemental trees is determined by:
(a) Assigning a tree unit to each supplemental tree using Table 16.52.090(D);
(b) Two supplemental trees shall be required for replacing each existing significant tree having a
diameter breast height of 24 inches and larger subject to the limitation in subsection
(D)(3)(d) of this section, and consistent with subsection (D)(2) of this section these shall be
counted first;
(c) The quantity of supplemental trees shall be of a sufficient number that their total assigned
tree units added to the net existing tree units shall equal or exceed the minimum required
tree units established in subsection (B) of this section; and
(d) Supplemental trees in excess of those needed to meet the minimum required tree units shall
not be required.
(e) See Diagram 16.52.090 for an example of calculating supplemental trees.

Commented [se26]: This allows for a substantial number
of trees to be removed. Does this achieve the intent of the
code or the comprehensive plan? In my opinion, this should
be removed. Has minimum 1:1 replacement ratio been
considered for trees less than 24"? Should there be
something similar to restoration 16.52.110?

16.52.100. Supplemental tree standards and priorities.
A. To be eligible as a supplemental tree, the tree species must be selected from the appropriate list set forth in
the "City of Medina List of Suitable Tree Species" established in MMC 16.52.060 and shall meet the following
general requirements:
1. Each supplemental tree shall have a minimum caliper of two inches, or, if the tree is coniferous, it shall
have a minimum height of six feet at the time of final inspection by the city;
2. Trees shall be planted in a manner of proper spacing and lighting that allows them to grow to maturity;
3. Existing trees within the boundaries of the lot having less than six inches diameter breast height may
count as supplemental trees provided the tree meets all other requirements applicable to a
supplemental tree;
4. Supplemental trees replacing existing significant trees shall have at least one tree be of the same plant
division (coniferous or deciduous) as the significant tree it is replacing; and
5. The owner of the subject lot shall take necessary measures to ensure that supplemental trees remain
healthy and viable for at least five years after inspection by the city and the owner shall be responsible
for replacing any supplemental trees that do not remain healthy and viable for the five years after
inspection by the city.
B. All trees used to satisfy the supplemental tree requirements of this chapter shall be included as a significant
tree for the purpose of this chapter.
C. Where supplemental trees are required pursuant to MMC 16.52.090(D), the trees shall be planted in the
following order of priority from most important to least important:
Commented [se27]: Projects are planting the same
species. Often vine maple and hinoki cypress, very small
trees. Require multiple species be planted, or only allow up
to a % of trees from a single species, or require same
species as replacement, or replacements need to be able to
achieve the size of the ones removed if canopy preservation
is the intent.
Commented [an28]: The list of suitable trees that count
for tree credits in Medina include several small trees. This
means that an existing on-site hinoki cypress or vine maple
could count as replacement trees when a Douglas fir or
Western Redcedar is removed. The small trees wont fill the
canopy like a native large tree.
Commented [se29]: There should be a limit on the
number of same species. Issue developing that everyone
wants to plant vine maple and hinoki cypress due to small
future stature of canopy and less resilient forest.
Commented [se30]: There is no system in place to ensure
the trees are being retained or are viable after 5 years. A
budget is needed to manage such an endeavor. Where is
the information to be housed?
Consider adding more trees to account for the ones that will
likely die over 5 years - typically 20% attrition.
Commented [se31]: There needs to be a way to track this
so that a new owner may be aware that a smaller diameter
tree is actually a significant tree.

G. Existing trees on site having less than six inches diameter breast height may be included as restoration trees
provided:
1. The subject tree is located within the boundaries of the lot; and
2. The subject tree meets all of the other requirements applicable to restoration trees.
H. The owner of the subject lot shall take necessary measures to make certain that restoration trees remain
healthy and viable for at least five years after inspection by the city and the owner shall be responsible for
replacing any restoration trees that do not remain healthy and viable for the five years after inspection by
the city.
I. All trees used to satisfy the restoration requirements of this chapter shall be included as a significant tree for
purposes of this chapter.
J. In lieu of the tree restoration requirements prescribed by this section, an owner may satisfy the
requirements for restoration trees by meeting the requirements for off-site tree planting set forth in MMC
16.52.100.
K. The restoration requirements in Table 16.52.110 for removing significant trees shall be waived if the
following criteria are satisfied:
1. The subject lot contains a sufficient number of significant trees to meet the preservation standard for
required trees established in MMC 16.52.090; and
2. The owner demonstrates that removal of the significant tree, including hazard and nuisance trees, will
not result in a failure to meet the preservation standards for required trees established in MMC
16.52.090.
Commented [se33]: Approvable reasons for removal are
identified in 16.52.010. B. 3. Are there other sections in the
code that provide other reasoning not to be considered
indiscriminate removal?
Commented [se34]: Why are lands under development,
where there is likely more issues related to tree canopy loss,
held to a lower replacement standard then lands not under
development?
Commented [se35]: Consider adopting enforcement
procedures for ensuring the supplemental tree 5-year
health/viability requirement.
Commented [se36]: Need to develop a tracking system to
ensure trees planted as supplemental trees are also
identified as significant trees.
Commented [se37]: You can remove trees as long as you
either replace or meet the minimum standards. This does
not meet the intent of 16.52.010 B 1& 5.

16.52.120. Hazard tree risk assessment.
A. Hazard trees are trees assessed by the city arborist as having a high to extreme risk rating using the
International Society of Arborists Tree Risk Assessment Qualification (TRAQ) method in its most current form.
B. Steps in the TRAQ method in developing a tree risk rating include the following:
1. Identify possible targets and estimate occupancy rate;
2. Inspect tree and identify tree parts that could fail and strike targets (referred to as failure mode);
3. For each significant failure mode identified:
a. The likelihood of failure is assessed;
b. The likelihood of a tree part impacting a target is assessed;
c. The likelihood of a tree failure impacting a target is assessed;
d. Consequences of failure are estimated;
e. The risk is designated pursuant to the matrix in Table 16.52.120(C);
f. Possible mitigation treatments to reduce the risk are identified;
g. The risk is again designated pursuant to the matrix in Table 16.52.120(C) after mitigation
treatment is completed.
4. When assessing the risk of a tree, the city arborist shall evaluate the tree based on existing conditions
and shall exclude possible impacts caused by new development, any land alteration activity, or other
similar such activities that might otherwise unnaturally cause the risk rating to increase.
C. The following table is from the International Society of Arborists TRAQ method and denotes the risk rating
matrix used to assess levels of tree risk as a combination of likelihood of a tree failing and impacting a
specified target, and the severity of the associated consequences should the tree or any part of the tree fail:
Table 16.52.120(C) Tree Risk Rating Matrix
Likelihood of
Failure or Impact
Consequences
Negligible Minor Significant Severe
Very likely Low risk Moderate risk High risk Extreme risk
Likely Low risk Moderate risk High risk High risk
Somewhat likely Low risk Low risk Moderate risk Moderate risk
Unlikely Low risk Low risk Low risk Low risk
1. The consequences listed in Table 16.52.120(C) have meanings as follows:
a. Extreme risk. This category applies to trees in which failure is "imminent" and there is a
high likelihood of impacting a target, and the consequences of the failure are "severe."

(Supp. No. 4)
Page 15 of 25
b. High risk. This category applies to situations in which consequences are significant and
likelihood is "very likely" or "likely," or when consequences are "severe" and likelihood is
"likely."
c. Moderate risk. This category applies to trees in which consequences are "minor" and
likelihood is "very likely" or "likely" or when likelihood is "somewhat likely" and the
consequences are "significant" or "severe."
d. Low risk. This category applies to trees in which consequences are "negligible" and
likelihood is "unlikely"; or when consequences are "minor" and likelihood is "somewhat
likely."
2. Definitions of TRAQ method terminology that are not set forth in this chapter or Chapter 16.12
MMC can be found in the article "Qualitative Tree Risk Assessment" by E. Thomas Smiley, Nelda
Matheny, and Sharon Lilly on file at Medina City Hall.
3. Potential targets are permanent structures or an area of moderate to high use. Where a target
does not exist, applicants should consider routine pruning and maintenance to mitigate hazards.
D. Where a tree is found to have a high or extreme risk, the city arborist may authorize hazard pruning to
mitigate the risk rather than removing the entire tree.
E. If the city arborist assesses a tree to have a high or extreme risk and mitigation of the risk through pruning or
moving of potential targets is not feasible, the city arborist shall designate the tree a hazard tree.
(Code 1988 § 20.52.200; Ord. No. 923 § 22, 2015)
16.52.130. Nuisance tree.
A. A nuisance tree, for purposes of this chapter, is a tree whose branches, stem and/or roots cause one or more
of the following conditions to exist:
1. Substantial physical damage to public or private structures;
2. A qualified professional provides verification based on conditions on the property that substantial
physical damage will occur within five years to a building containing a principal use;
3. Substantially impairs, interferes or restricts streets, sidewalks, sewers, power lines, utilities or other
public improvements;
4. Substantially impairs, interferes, or obstructs any street, private lane, or driveway; or
5. The tree is diseased and restoration of the tree to a sound condition is not practical.
B. Designation of a nuisance tree is by the director following receipt of a written request and findings are made
supporting a nuisance designation using the following criteria:
1. One or more of the conditions in subsection (A) of this section is present;
2. The nuisance associated with the subject tree cannot be corrected by reasonable measures including,
but not limited to, pruning, cabling, bracing, or if feasible, relocating structures and other
improvements; and
3. Other relevant information provided by the applicant and the city's inspection of the subject tree.

16.52.150. Notice of tree removal involving no construction.
A. Property owners removing a significant tree requiring a permit under MMC 16.52.160, but not undergoing
new construction or land alteration activity, shall notify the city at least ten calendar days prior to the date
the tree will be removed. The director may reduce this time with receipt of a written request from the
applicant and upon finding that the lesser time will provide the city reasonable notification.
B. All property owners removing a nonsignificant tree that does not require a permit are encouraged, but not
required, to notify the city of the tree removal at least 48 hours prior to the tree being removed.

requiring a permit must still comply with this chapter.
B. An administrative tree activity permit meeting the requirements set forth in MMC 16.70.050 is required for
the following activities unless a permit is required elsewhere under this section:
1. Land designated under development as determined in MMC 16.52.070;
2. Removal at of any time of a significant tree, including hazard and nuisance trees, located on private
property or state controlledstate-controlled land associated with the SR 520 highway;
3. Removal of any nonsignificant tree, including hazard and nuisance trees, located on private property or
state controlledstate-controlled land associated with the SR 520 highway that is located within 200 feet

4. Removal or pruning of any tree that is:
a. Six inches or larger diameter breast height size;
b. Located in any open or closed city right-of-way; and
c. Designated a hazard tree pursuant to MMC 16.52.120, or involving hazard pruning authorized by

regulations).
B. The director may authorize modifications to the tree preservation plan on a case-by-case basis that reduce
submittal requirements if the director concludes such information to be unnecessary.
C. The director may require additional information to be included with the tree preservation plan, such as tree
protection measures, where the director concludes the information is necessary to determine compliance
with this chapter.

plans.
B. Tree protection measures shall include, but are not limited to, the following:
1. Establish tree protection zones and install protective fencing at the drip line or other barriers that are
at least four feet in height, except where tree protection zones are remote from areas of land
disturbance, and where approved by the director, alternative forms of tree protection may be used in
lieu of tree protective fencing; provided, that the critical root zones of protected trees or stands of
trees are clearly delineated and protected;
2. Limit grading levels around subject trees to not raise or lower grades within the larger of the following
areas:
a. The drip line area of the tree; or
b. An area around the tree equal to one foot in diameter for each inch of tree diameter measured
at DBH;
3. Installation of a tree well, but only where necessary and only with pre-approval of the city;
4. Designation of areas on site for parking, material and equipment storage, construction ingress and
egress, and similar designated areas that do not negatively impact significant trees;
5. Locate trenches for utilities that minimize negative effects on the tree root structure with provisions
for filling the trenches with a suitable growing medium in the vicinity of the trees;
6. Employ measures to protect critical root systems from smothering and compaction;
7. Implement a tree care program during construction to include watering, fertilizing, pruning and pest
control; and
8. Measures for the disposal of potentially harmful items such as excess concrete, polluted water runoff,
and other toxic materials.
Commented [se49]: This guide does not have the fees
but has a method to determine a cost for replacement.
Commented [se50]: The tree care program should be
included either on a plan or a submitted report.
Unfortunately, this is often overlooked. There is no way to
know if the program is being implemented outside of
arborist inspections.
