Development Activities Report
Staff Lead: Shane Hope
Department: Planning Division
Prepared By: Diane Cunningham
Background/History
In recent years, the Development Services Department has been reporting annually on key development
projects and activities.
Staff Recommendation
Narrative
2017 was a strong year for development in Edmonds. The most ever building permits were issued in
2017 and the total valuation for those projects was greater than any other year. While this level of
activity is not likely to continue year after year, it is a sign of two things: (1) the regional economy and
market is strong; (2) Edmonds is a place that both residents and businesses want to be.
A slideshow will be presented on April 24 to highlight some of the more significant developments that
either were recently built or are "in the pipeline", along with a few other related department activities.

Public Hearing on the Draft Urban Forest Management Plan
Staff Lead: Shane Hope
Department: Planning Division
Prepared By: Diane Cunningham
Background/History
Although old growth trees in most parts of Edmonds were removed long ago, today, a variety of trees
can be found on every block. The City of Edmonds has, for many years been involved in the protection,
planting, and management of trees. The subject is not without controversy.
Edmonds has certain regulations in its code about the cutting, maintenance, and planting of trees.
Permits are required for removing trees in environmentally critical areas. It also has a Street Tree Plan,
identifying types and locations for planting trees along specific streets, and a Comprehensive Plan that
refers in several sections to the desirability of trees. Furthermore, the City has a Parks Department and
Public Works Department that provides services for trees in parks and the public rights -of -way. The City
also sponsors or co-sponsors events for tree planting and tree care. A City Council -appointed Tree
Board carries out a range of duties and activities, including annual Arbor Day planting. Edmonds is a
certified city in the Tree City USA program.
About two years ago, a proposal came forward, initiated by the Tree Board, to amend the code in a way
that would set significant tree requirements on private property. The resulting draft ordinance was met
with a mix of support and resistance. After a public hearing on the proposal, the Planning Board
recommended that the draft ordinance not move forward for adoption and that tree issues be
considered in an alternative manner, particularly through an urban forest management plan.
[NOTE: "Urban forest" is a term that refers to all the trees in an urban area.]
The City Council accepted the Planning Board's recommendation and, in the following year, allocated
funding to develop an urban forest management plan. The primary focus --though not the only one --was
to consider forest issues on public property. In addition, the plan was intended to identify opportunities
for encouraging good tree management on both public and private property. The Department of
Development Services, in consultation with the Parks and Recreation Department and the Public Works
Department, took the lead in hiring an experienced consultant to help develop the urban forest
management plan.
In April 2017, as part of an initial outreach program, members of the consultant team (led by Davey
Resources Group) and City staff met with the Tree Board about their interests and ideas for the plan.
Additional research and stakeholder information followed. In July 2017, the consultant and City staff
met with the Planning Board to get the Board's initial input. (See attached minutes, Exhibit 1, from that
Packet Pg. 43
6.A
meeting.)
Other public information and input opportunities have included:
Press releases and local news articles
Special City webpage with information updates
Public Open House - June 22, 2017
Online survey (posted for about 3 months)
Tree Board meeting - April 5, 2018
Public Open House - April 19, 2018.
Following the April 2018 meetings, the City received several written public comments (see Exhibit 2).
Minutes from the Tree Board's April 5 meeting are attached as Exhibit3.
Highlights from the April 19 Open House are attached as Exhibit4.
Staff Recommendation
Consider information and prepare a recommendation to the City Council.
Narrative
OVERVIEW
The draft Urban Forest Management Plan (UFMP), dated May 2018, is attached as Exhibit 5. It is slightly
revised from the March 2018 version reviewed in public meetings held in April. The revisions reflect
minor corrections and clarifications to the background information. Probably the biggest change is that
the "Benefits" section has a brief new section about "Challenges" for the urban forest. Also, a reference
to forest information from the Washington State Department of Natural Resources has been added.
The actual recommendations for future City action were not modified (except for any "housekeeping"
changes).
[NOTE: The May draft still is missing some photos that can be added later. It also does not yet have an
approximate time period or level of cost for achieving the proposed objectives. Presumably, some
objectives and actions, if adopted, could be part of regular City activities during the next year or so;
others may take additional resources.]
According to the draft UFMP, about 30% of the City is covered by tree canopy. The majority of tree
canopy is on private property, where owners maintain the trees. The City has a role in regulating some
aspects of private tree management and also in encouraging/educating people to plant and protect
appropriate trees. Meanwhile, the City directly manages and is responsible for all trees on City property
and in the public right-of-way.
Recommended goals and actions comprise a large part of the draft UFMP. These include:
7 "urban forest" goals
8 "municipal" goals
6 "community" goals.
Although the 21 goals are categorized for ease of reference, many of them are interrelated. That is,
"municipal" and "community" goals are not exclusive of one another. Also, each of the goals is
Packet Pg. 44
6.A
associated with multiple actions. For example, the goal of conducting an inventory of publicly -managed
trees to document tree condition and risk (UF Goal # UA 6, page 64 of the draft plan) has four key
implementation actions: (A) Develop a tree inventory policy for public trees; (B) Develop a standard tree
inspection protocol; (C) Integrate inventory data into easily accessed software or data management
system; and (D) Develop a policy and responsibility for keeping inventory data up-to-date.
Achieving each of the goals and actions (as ultimately adopted) will take time and resources. Some of
them may be relatively easy and others more difficult. The draft plan also notes that monitoring and
measuring results of the strategies will be important.
The Planning Board is encouraged to pay particular attention to the proposed goals and actions on
pages 59-80 of the draft plan. Adoption and implementation of UFMP goals will require considerable
attention and resources over the coming years.
NEXT STEPS
The May 9 public hearing is another opportunity for the public to comment on the draft UFMP and for
the Planning Board to consider information. (See Exhibit 6 for the presentation that will be given on
May 9.) After the public hearing --either on the same night or later --the Planning Board may make a
formal recommendation to the City Council about actions to take. If the Planning Board wishes to
recommend any changes to the background part of the draft UFMP, that would be helpful in finalizing
the draft before it goes to the Council. (Staff is working with the consultants on adding background
information to the draft UFMP, for example, regarding tree species, diseases, and insect damage.) Any
proposed changes to the plan's recommendations--i.e., the Objectives and accompanying Actions,
should be identified as part of the Board's formal recommendation to the City Council.
Again, the Planning Board may make its formal recommendations on May 9 after the public hearing or
may set aside time at a subsequent Board meeting to finalize recommendations. The Board's next
meeting (after May 9) is May 23. By that date, additional information may have been added to the
background sections of the draft UFMP.
On June 19, the City Council is tentatively scheduled to hold a public hearing on the draft UFMP. Further
Council consideration is expected at a June 26 meeting. Another tentative date, July 3, is for additional
discussion and potential action.
Potential Council actions may include:
1. Adopting the proposed UFMP without substantive change;
2. Making specific changes to the proposed UFMP before adoption;
3. Requesting changes to be made and then re -presented.
Once a plan is adopted, implementation would begin.

UPDATE ON DEVELOPING THE URBAN FOREST MANAGEMENT PLAN
Ms. Hope explained that the City is currently working to develop an Urban Forest Management Plan (UFMP) that will
primarily focus on managing trees on public properties and in public rights -of -way. She introduced Ian Scott, Davey
Resource Group, who was present to provide an update on the plan.
Ian Scott, Davey Resource Group, introduced the other members of the consulting team: Keeley O'Connell with Nature
Insight Consulting and Ian Lapport from the Davey Resource Group. He explained that the definition of an urban forest
includes both public and private trees within the City limits of Edmonds. Wherever the trees are, they provide benefits to the
entire City. The UFMP is being developed as a guiding document for forested land on City properties, public rights -of -way
and critical habitat areas. It should fall under the Comprehensive Plan, align with the Parks, Recreation and Open Space
(PROS) Plan, and provide an overarching guiding document for the Public Works, Planning and Parks Departments. The
plan will contain both long and short-term goals based on adaptive management principles. The intent is that it be a long-
term planning document with the expectation that it would go through routine revision exercises over time as community
values change.
Mr. Scott said a UFMP is important to promote a shared vision, communicate the value and benefits of trees, and allow
multiple city departments to manage all of the challenges and opportunities that come up relative to trees. The plan is
intended to create a pathway for pro -active management. The process starts by determining what the City has and wants, and
then identifies goals that will help the City move towards its vision.
Mr. Scott reviewed that the process thus far has included stakeholder interviews with the Parks, Recreation and Cultural
Services staff, Development Services staff, Public Works Staff, and the City's Tree Board. These meetings have provided
opportunities to share thoughts, visions, and challenges with working with trees in the City. The team has also done
document research to pull together all code and Comprehensive Plan language related to trees. An Urban Tree Canopy
Assessment was completed, and one community visioning session was held on June 22nd. The team is poised to release a
virtual open house for those who were unable to attend the visioning session.
Mr. Scott stated that the Urban Tree Canopy Assessment started with a 2017 aerial imagery and used a computer -automated
process (GIS) to identify the existing tree canopy, impervious surfaces, grass/vegetation, bare soils, and water. As an
example, he displayed a graphic of the Edmonds Marsh. He summarized that the results of the assessment show that the
City's tree canopy covers about 30% of the City. He explained that the information obtained via the assessment allows for a
GIS overlay on various other mapping elements. For example, the data can be viewed based on:
• Land Type (commercial, public and private properties). He noted that 80% of the existing tree canopy is located on
private lands, so a good portion of the UFMP will require some volunteer buy -in from the community in order for it
to be successful.
• Forest Fragmentation. About 190 acres of the forested area is of core canopy that provides for habit for wildlife.
For movement, more of this type of canopy is needed. There is a potential for a stronger rebuild moving north to
south across the City using perforated canopy and patch canopy.
Canopy Benefits. To date, trees in Edmonds are storing 188,000 tons of carbon, valued at $6.8 million in
environmental benefit or avoided environmental degradation. Annually, trees in Edmonds provide $1.2 million in
stormwater benefits, $147,000 in air quality improvements, and $222,000 in carbon sequestration. If the trees are
removed, air quality would go down and illness would increase.
Mr. Scott provided a graph to show how the City's 30% tree canopy compares with other cities in the region. He noted that
both Bonney Lake and Lake Forest Park have a 40% canopy cover. The City of Edmonds' canopy is very similar to that of
Shoreline and Redmond.
Lastly, Mr. Scott reviewed the timeline for the project, noting that the consulting team is currently drafting the UFMP, and
the online survey is still open. The draft UFMP will be submitted to the City in August and September, and this will be
followed by a review period. The consulting team will present the draft plan to the Tree Board, City Council and Planning
Planning Board Minutes

Board. There will also be an additional public open house. He stressed the importance of public feedback as the document
moves forward. He concluded that a second draft of the UFMP will be available by November, followed by a final draft in
December. It is anticipated that the City Council will approve the document in the spring.
Mr. Scott advised that public voting boards were provided at the June 22nd open house to solicit public opinion. It appeared
that the majority of those in attendance lived in the bowl area, and there was strong concern that the plan would have negative
impacts to the Tree Code. Concern was raised about the previously -proposed tree code, and most indicated they did not want
the UFMP to go that direction again. He emphasized that the UFMP is not intended to revise City Code, only to propose
options that, if desired, would get you down the road into the future. He reviewed the results of the six questions that were
asked as follows:
• What tree benefits do you most appreciate? Most attendees indicated that water quality, wildlife habitat, air
quality and beauty/aesthetics were most important.
• What types of outreach and education are preferred/valued? The plan will include a component of education
and outreach to change people's attitudes and culture. Attendees specifically recommended education and outreach
pertaining to species selection and tree pruning.
• What is/are your biggest concerns for trees in Edmonds? Many attendees were concerned about trees blocking
views, but others were more conserved about healthy, mature trees being lost, canopy loss, and loss of wildlife
habitat.
• What level of maintenance would you prefer for public trees? A UFMP can result in increased activity
sponsored by the City or it can be reduced, as well. Most people indicated a desire for the City to take care of its
hazardous trees, and maintaining access and clearance on roadways. There was no support for doing nothing
moving forward, which means they want some level of care from the City.
• Where would you like to see more trees planted? Responses were spread nearly even across all of the options
(parks, open spaces, commercial properties, streets/medians, parking lots, and private properties). The consultant
team translates this to mean that anywhere trees are planted in the City provides a value to the community.
• What are the best ways to encourage tree planting and preservation on private property? Most attendees
indicated that education and outreach, as well as free or low-cost trees, would be the most effective way of
encouraging tree planting and preservation.
Mr. Scott invited the Board Members to share their ideas, for planting more trees along City streets, as well as opportunities
for education and community building. He also invited them to voice their issues and concerns. In addition, he encouraged
Board Members to participate in the on-line survey, which can be found at https:Hsurveymonkey.com/r/EdmondsUFMP.com.
For more information about the value and benefit of trees, he encouraged them to visit the following websites:
https://.treesare og od.org, hlWs://www.treebenefits.com, and https:Hitrectools.org.
Board Member Rosen asked how many people attended the public open house, and Mr. Scott answered that about 50 people
were in attendance. Board Member Rosen said Mr. Scott noted a 2.3% decrease in the City's tree canopy since 2005 and
asked if this represents a steady decline or was it caused by a single event. Mr. Scott answered that the methodology is not
conclusive on cause. Board Member Rosen asked if the analysis identifies where the losses occurred. Mr. Scott replied that
the change analysis was a statistical exercise that did not produce a map. Board Member Rosen asked how the City's current
rate of tree canopy loss compares to that of other jurisdictions. Mr. Scott said he does not have that information.
Board Member Lovell commented that much of the information presented to the Planning Board could be considered "off the
shelf." He said he attended the I't public open house and filled out a comment card, as did a number of other people who
attended. However, the consultant's presentation did not include any of the comments received to date. For example, some
people suggested that the City hire a full-time arborist, and it is likely that someone else suggested that the City create an
Open Lands Trust Fund. He suspects that a number of comments were received suggesting that the City not regulate trees on
private property. Mr. Scott agreed that the presentation was somewhat "off the shelf." He noted that a summary was

prepared of the public comments received at the meeting, and they will be considered as part of the planning process. Board
Member Lovell asked if the comments received to date represent any sort of trend. Mr. Scott said a number of people have
come forward voicing opposition to regulating trees on private property. There is also a number of people who are
passionate about trees and want to regulate trees on private property. He said he is hoping the online survey will provide a
greater indication of public sentiment. There is no urgency to close the survey at this time, and they are hoping to get more
people to respond.
Vice Chair Monroe referred to the goals that were presented by Mr. Scott. He suggested that rather than "placing trees in
Edmonds," a more appropriate goal would be to "place the right trees in Edmonds." He noted that some of the public trees
are not the right species, and they end up invading sidewalks and sewer systems. This should be addressed in the plan. He
also noted that, although the consultant provided a slide indicating the "benefits" of trees, there was no information about the
"costs." Mr. Scott responded that the consulting team is working with data from the Public Works and Parks Department to
address the costs associated with the care of trees. The biggest challenge is that the City does not have an inventory of the
existing trees they are spending money on or trees that have unresolved issues. The only data he has found is a list of all the
sidewalks that are heaving, likely caused by trees. He said the plan will include a list of trees that are subject to mortality
because they are not in the correct place for the species.
Vice Chair Monroe asked how the UFMP and Tree Plan would impact the Highway 99 Subarea Plan. Ms. Hope recalled that
the Highway 99 Subarea Plan talks about using the City's Street Tree Plan as an indicator of the types of trees that should be
planted. The Street Tree Plan has a section that specifically refers to the Highway 99 Subarea, but it needs to be updated at
some point in the near future. Information provided in the UFMP could inform this update. Mr. Scott said it is important to
recognize that the UFMP will be a strategic plan for the City, and the elements contained in the Street Tree Plan are more
operational planning tools. For example, to learn the right trees to plant along a street boulevard, you would go to a tree
planting pallet list contained in the Street Tree Plan. The UFMP will refer to the recommended tree planting list contained in
the Street Tree Plan.
Board Member Robles asked if the aerial photographs are only a data point, or are there other means for measuring trees,
such as measuring the mass of the tree stock to determine the difference between a shrub and a large tree. Mr. Scott said the
analysis used a multi -spectral imagery, which differentiates between tree canopy and low-lying vegetation. He agreed to
provide more information about how the differences are identified on the maps.
Rather than imposing more barriers on development, Board Member Robles asked if there are incentives the City could offer
to developers to retain trees or build structures that are not susceptible to tree damage. He recalled that the Board is also
working on an emerging "aging in place" plan that would allow property owners to build an extra dwelling unit on a single-
family lot, saving it from being redeveloped to a greater density. This would result in tree retention, as well. He asked if the
consultant has considered other tangential activities that could have an impact on the City's effort to retain trees. Mr. Scott
answered that the UFMP would not reach that level of detail, but it may describe some incentives to encourage alternative
building placement to encourage retention of larger trees. Another solution that other cities are exploring is developing a
type of "tree bank." This would allow developers of properties that do not have enough space to accommodate trees to pay
into a fund for planting to occur in another part of the City.
Board Member Robles asked if the canopy analysis accounts for tree growth. Mr. Scott answered no and explained that the
analysis can only describe the quantity of a forest and not the quality. He has heard reports from the Parks Department that
there are a number of alder trees that are aging and in decline. They are having to spend a significant amount of money to
replace them. He explained that the mortality rate for the urban forest canopy would require some additional study, and it is
very typical for a city to move from a canopy study to a tree inventory as a benchmark for studying tree growth. Board
Member Robles commented that if the City has an idea of how much the trees are growing, it will also have a better idea of
how many are being lost. This would allow them to better structure the plan to address the delta. He said he is looking
forward to seeing a higher level of data at some point in the future. Mr. Scott said the scope of the current project is to
establish some benchmarks, identifying what the City has and does not have. This additional information will likely be
identified as a goal item in the UFMP.
Board Member Robles suggested that the UFMP could recommend a program that allows property owners to self -register the
trees on their property. Given that trees grow at a certain rate, property owners could receive credits for tree growth. Mr.
Planning Board Minutes

6.A.a
Scott said there is a lot of precedence for this approach with the citizen science movements going on. With the advent of
handheld mobile devices, they are able connect property owners to the trees on their property and give them ways to
participate in the fact-finding process. Board Member Robles suggested that this concept be included in the list of things the
City wants to do.
Board Member Lovell asked if there is anything the consultant can show the Board that represents what the final report will
look like. Mr. Scott referred to the City of Kirkland's UFMP, which was recently done by his firm. He agreed to provide a
link to the document. There is emerging research and precedence in the industry that will provide guidance for the plan.
Board Member Lovell commented that there is a strong interest that emerges to compare Edmonds with other cities in the
region. It would be helpful to have information showing what the cities that have greater tree canopy than Edmonds look like
in 2017. A lot of development has occurred in these communities since 2011 and 2012, and their tree canopy has likely
decreased as a result. Mr. Scott said each of the cities pay for the analysis to be done, and he can only provide information
from cities that have made their findings publicly accessible. The comparison provided in his presentation was based on the
knowledge he had from doing work in the cities. Board Member Lovell asked if the City could order a colored graphic
spectrum analysis from the cities included in the comparison. Mr. Scott said it would be uncommon, but the City could
certainly do that. On the flip side, he would expect that most of the cities would be updating their analysis by 2022. Another
way that cities keep an eye on canopy change is via permit processes. Although the permits may not require tree retention,
noting it on the application would at least provide the City with a record of the number of trees lost.
Board Member Rosen asked if there is an ideal percentage for tree canopy based on best management practices and expert
knowledge. Mr. Scott answered no. The ideal percentage varies from city to city. American Forests used to promote a 40%
tree canopy that every City should have as a goal, but they have since retracted to recognize that different cities have different
capabilities. Vice Chair Monroe summarized that Lake Forest Park's 40% canopy may not be better, it is just different. Mr.
Scott agreed and added that Lake Forest Park has a different character than Edmonds.
Board Member Robles noted that the United States Forest Service (USFS) does Lydar surveys of their assets, and perhaps
cities could get together to fund a similar study. Mr. Scott agreed that is possible. He noted that USFS ran a Forest Inventory
Assessment in 2013 for not only forested lands, but various urban areas, as well. This information is available to the public.
Board Member Robles asked if this type of study would be a better asset than the City's current methodology. Mr. Scott
answered affirmatively, because it talks about the quality of the forest. The condition assessment is missing from the Urban
Tree Canopy (UTC) survey, but the UTC survey is still very cost effective. Board Member Robles commented that, although
it would be too costly for Edmonds to do its own Lydar survey, perhaps cities could get together to perform a Lydar survey
on a larger stretch of land. Mr. Scott suggested that Lydar is becoming more accessible and definitely will be part of the
future. Mr. Chave noted that the City has done some Lydar work, and it is available online.
Board Member Cloutier said he appreciates that the objective of the UFMP is not to maximize the tree canopy, which would
be impractical, but to find the right balance. It's important to make this clear to the public because there tends to be a
reflexive reaction of "all or nothing" either way. He reminded the Board that the City Council recently adopted a resolution
supporting the Paris Climate Accord. As part of that resolution, there were specific objectives for having Edmonds transition
to a completely carbon -free energy source. Given the City's location, that pretty much means solar energy. He suggested
that efforts to promote the use of solar photovoltaic energy should be done in conjunction with efforts to increase or find an
optimal tree canopy. He noted that concerns about trees shading yards could be related to the need for solar access for energy
or for gardens. He expressed his belief that the Street Tree Plan will need to be revised in concert with implementation of the
UFMP.
Board Member Cloutier suggested the UFMP should also include another tier of vegetation other than the very large trees.
For example, someone with a solar easement may still want vegetation on the ground. This would provide all of the benefits
that vegetation provides, just not at the scale of a huge Douglas Fir. Mr. Scott said the challenge is that woody plants will
sequester carbons, but not as much because they don't have the same leaf area. Studies show that while it is a challenge to
grow large trees in the urban environment, they provide the most long-term benefits. Board Member Cloutier expressed his
belief that "halfway there is better than none." Again, he suggested that another tier of vegetation be considered in places
where a massive tree is not appropriate. Mr. Scott said the UFMP will be strategic, allowing the City to make decisions that
Planning Board Minutes
July 26, 2017 Page 7
Packet Pg. 50
6.A.a
certain trees need to be removed. Planting trees in other places will allow the City to balance the canopy out to create a
sustainable urban forest. Right now, the City does not have adequate information to make these balanced decisions.
Due to the way the City is oriented towards the water, Board Member Cloutier cautioned that anything that affects views will
multiply any opinion by 1,000. Views will be the primary consideration for most people. Chair Rubenkonig pointed out that
trees planted within the public rights -of -way have obscured the views of the Sound that was once enjoyed.
Chair Rubenkonig commented that the Board is interested in facts, which will inform them as to the best way to address the
concerns raised by the citizens relative to trees in Edmonds. While she appreciates the information provided by the
consultant, she felt it would be helpful to have a historic overview of what has happened with the tree canopy over time.
Perhaps this could start with the 1960s photograph in the Public Works Building that shows how well treed the downtown
area was. They need to look at what has been done to the tree canopy as a result of the City's policies and the way that
business has been conducted. This information would help the Board consider the changes that are needed for the future.
Mr. Scott said the challenge with digging that far back is that aerial imagery from that period is black and white and not as
detailed. It is a safe assumption that the entire area was originally forested and later settled. The Planning Department has
indicated that most of the City has been developed at this point, and it is a matter of zoning amendments that have allowed
for greater density and resulted in loss of tree canopy. Chair Rubenkonig agreed that different tools would need to be used,
but she would like historic information to be part of the report.
Chair Rubenkonig said she does not consider the City's 30% tree canopy to be good enough. She suggested that the City of
Kirkland may have a greater percentage of tree canopy because they have a stronger tree policy within their development
regulations. She commented that her firm has worked on development projects in the City of Kirkland, and she knows that
they require a much higher tree retention, as does the City of Redmond. She summarized that the cities with greater tree
canopies may be reflective of more stringent tree retention policies.
Chair Rubenkonig suggested that in addition to addressing the issue of "planting the right tree in the right place," the UFMP
should also address using the right installation for trees that are planted. If a tree is planted in the right way within a sidewalk
area, it can prosper. Improper installation is often the cause of trees impacting sidewalks. She noted that, via the survey and
community open house, the public has indicated a desire for more educational information on how to plant trees correctly.
Mr. Scott commented that the UFMP can create great opportunities for community engagement by giving the City direction
towards setting up these relationships so that citizens can become stewards of their own land.
Chair Rubenkonig stressed the need for benchmark figures from the consulting team. She recalled that when the Board
conducted a public hearing on the Tree Board's previous recommendation, she got the feeling that citizens take trees very
seriously, particularly those on their own property. Most people have good intent to be good stewards of the land. However,
a lot of tree cutting has occurred in recent years as a result of people becoming afraid after major windstorms have occurred.
Many have felt the need to protect their properties.
Ms. Hope reminded the Board that the UFMP will come back to them for future work as the plan progresses. It will also be
presented again to the Tree Board. There will be a number of opportunities for the Board and members of the public to
comment as the plan progresses.
NEW BUSINESS
There was no new business.
REVIEW OF EXTENDED AGENDA
Ms. Hope reviewed the Board's extended agenda, noting that the August 9th agenda will include a presentation on completion
of the Sustainable Cities Partnership with Western Washington University (WWU). She reviewed that the WWU students
and faculty did a tremendous amount of work, and highlights of their work will be presented to the Board. The highlights
will also be made available online. The second item on the August 9th agenda is a presentation of information that has
recently been published about growth trends in the Central Puget Sound Region. This information will help provide context
for how Edmonds is performing as part of the larger region.

Edmonds UFMP Draft, March 2018
Comments on Part 1 "What Do We Have?" by Steve Hatzenbeler, Citizens' Tree Board
1. Page 1, column 2, "abundant": the use of subjective terms like this should be avoided.
2. Page 2, column 2, "comprehensive": No on -the -ground assessment was completed, so I would be
hesitant to call the review comprehensive.
3. Page 2, Table 1, $7.74: This was inflated in 2017 due to the UFMP expenditures. Not an accurate
representation of typical per capita investment.
4. Page 3, column 2, "the City does not have a method to take inventory or track the history, status,
or location of public trees": Seems like this is something that should be changed/fixed. Is DRB
recommending that the City start tracking it?
5. Page 5, column 2, "they also look for opportunities to plant trees in strategic public places": I don't
think this is accurate. Is City staff (besides the Parks Dept) really looking for opportunities to plant
trees?
6. Page 6, column 2, "20-year timeline concluding in 2048 (2038)... achieved by adapting the Plan
according to five-year cyclical review of operational objectives.": Is the City committing to these 5-
yr cyclical reviews of operational objectives?
7. Page 7, column 2, "...especially focusing on public land and rights of way. For private lands, the
UFMP would guide education and incentives to encourage good tree management practices.":
This sentence implies that the Comp Plan focuses on public right of way and land, but I don't think
that is actually in the Comp Plan. This should be reworded.
8. Page 9, column 2, Intercepting Rainfall: It may be beneficial to add context here that relates
rainfall interception to reducing stormwater runoff and urban flooding. I think people will
recognize these as problems in Edmonds.
9. Page 11, Table 3: Reduced atmospheric carbon (pounds): This is pounds per year, correct?
10. Page 12, column 1, "Impervious surfaces in 2011 were assessed as 34% of the total land base
(Edmonds, 2017).": This seems like awfully old data. Why not use the current data in the TCA. See
Land Cover Map 1 on page 22.
11. Page 12, Table 4: This is not mentioned in the text so it's hard to understand its value/place in the
report.
12. Page 13, Table 5: This data would benefit from being discussed in the text of the report.
13. Page 14, column 1, Aesthetic, Habitat, Socioeconomic, and Health Benefits: may be useful to
mention a counterpoint here that trees in view areas may contribute to lower property values and
strained neighbor relations. View areas are a significant complication in many parts of Edmonds,
and seem to not be accounted for in the UFMP so far.
14. Page 15, column 1, "...to understand and manage the urban forest has depended upon which
trees are being considered and where trees were located.": This is really awkward wording and
should be rewritten to get the point across.
15. Page 15, column 1, "In 2015, one of the efforts of this board was a proposal to the City for
updated tree -related municipal ordinances.": This is an incomplete representation of what
happened, and if it needs to be brought up in the UFMP (the value of mentioning it is
questionable, in my opinion), it should be more completely explained. Development Services was
intimately involved in the proposed ordinance every step of the way, it was not just the Tree
Board's proposal.
16. Page 16, column 2, "It is important that the City plan for all the trees in the urban forest as a
whole, not just critical areas.": If this is the case, shouldn't we address the other 83% of the
canopy that's not in public property and rights of way?
Packet Pg. 52
6.A.b
17. Page 17, column 1, "...should be integrated into land use and development codes.": Is this meant
to suggest that land use and development codes in Edmonds will be updated to include tree
retention requirements?
18. Page 18, column 2, "...care for the urban forest is mandated.": This statement implies the entire
urban forest, not just the 13% of it that happens to be on public right of way.
19. Page 18, column 2, "...strategies to improve the care and conservation of all trees.": All trees. So
how does this UFMP improve care and conservation of trees on private property?
20. Page 19, column 2, "Current operations in the City that care for the community trees do not keep
suitable records of their tree resource to summarize within this UFMP.": This sounds like
something that should be addressed/fixed.
21. Page 20, column 2, "...provide benefits to the community beyond property lines.": This point
should be hammered home more strongly; it is very important for the community to understand
trees as a community resource, not just individual trees on single parcels.
22. Page 21, column 2, "...suitable planting sites (1,651 acres)": Is this only on public property and
rights of way, or does it also include private property?
23. Page 25, column 2, "Haines Wharf is another example where the potential canopy (40.6%) is much
higher than the existing canopy (11.9%).": It should be noted that big increases in tree canopy
cover at HW Park would affect views on the hill above the park. This will not be practical or
accepted by the community. Situations like this will reduce the effective potential gains in canopy
gain at HW Park and other places like it, and the potential tree canopy gains should be adjusted to
reflect that.
24. Page 29, Table 10: View impacts (or potential view impacts) should be factored into this table,
maybe with a negative weight factor. This would lower the priority of planting in areas where
views could be affected by tree planting. View impacts cannot be ignored by this plan.
25. Page 30, Table 11: Much of the high and very high priority planting areas are in view and private
property areas. I don't think view impacts should be ignored. The impact on views should be
factored in and reduce priority of certain areas.
26. Page 31, column 1, "Edmond's": Correct spelling (numerous spelling errors throughout
document).
27. Page 31, column 1, "The stored carbon is valued at $6.8 million.": In my opinion it would be
valuable to provide an explanation of what this means, and how a value is assigned to stored
carbon.
28. Page 32, column 1, "Use GIS canopy and land cover mapping to explore under -treed
neighborhoods and identify potential planting sites.": Seems like this should be included in the
UFMP. This statement suggests that identifying future planting sites would be done later by urban
forest managers --who don't exist in Edmonds.
29. Page 32, column 1, "Incentivize tree planting on private property, particularly in high/very high
planting priority areas.": But be wary of impacts on views. Views just don't seem to be factored
into this UFMP yet, and in Edmonds, they can't be ignored in a successful and meaningful UFMP.
30. Page 32, column 2, "Define canopy goals and identify actions that will support these goal(s).": Isn't
this UFMP supposed to define the canopy goals and identify actions that support these goals?
That seemed to be one of the primary reasons the UFMP was proposed a few years ago.
31. Page 34, Table 13: Should be 2017, not 2016.
32. Page 34, Table 13: The total is inaccurate, and should be $319,542.
33. Page 38, column 2, "Currently the City of Edmonds dedicates $319,542 towards total community
forestry expenditure": Specifically in 2017. This statement suggests that the $319k expenditure is
a budgeted annual expense, which it is not.
Packet Pg. 53
6.A.b
34. Page 38, column 2, "...per capita investment of $7.74.": Significantly inflated in 2017 due to the
cost of the UFMP.
35. Page 39, column 1, "Create regulations...": This is odd wording; "These regulations are designed
to" create regulations? Should be stated differently.
36. Page 39, column 2, "All street trees are managed by the Public Works Department.": Seems to
more commonly be managed by Parks, not Public Works

Subject: UFMP Comments
Hello,
below are my comments regarding the Draft Urban Forest Master Plan for
Edmonds. First of all, thank you to the City for opening up this process to the public for
input and examination!
I think efforts to protect, maintain and foster health trees are supremely important. My
main comment would be to encourage the City to either implement, or find out how to
implement, more control over trees (and there removal) on private property. I
understand that ability to do so is -possibly- limited on private property, because trees
are that, property of the owner. However, I think that trees should be considered a
very important benefit to the community as a whole, and therefore more strongly
regulated.
If, as stated in the document, private owners control the majority of the tree canopies,
then I believe a great deal of the focus from the City should therefore be on protecting
those trees. If that amount of homeowners cut down all of those trees the City would
only be left with a 17% tree canopy.
Although it may seem a stretch, this could feasibly happen with current lack of
regulation. And what is stopping homeowners and developers from doing this? Do we
want to see an Edmonds that is void of it's beautiful trees?
Off site land owners may not care much whether or not there are trees on the property,
and often times it is easier to cut down the trees to make way for development, rather
than to try and preserve them.
Good, health, mature trees take a long time to grow. While developers may have to
plant new trees in place of any of those removed, it is not an apples to apples
exchange. A small, cheap, (possibly not native) deciduous tree purchased at a home
improvement store does not provide the same benefits to wildlife, and to the air, as a
long standing, native mature tree does. I believe it is extremely unfair and unwise to
allow that kind of exchange.
Please consider more regulations on private property owners, for the sake of the
beautiful community we live in.
Thank you,

Subject: Comments for the 4/5 Tree Board Meeting
Hello,
I am unable to attend the Tree Board meeting scheduled for tomorrow at 6pm. I wanted to
submit my public comments about the draft Urban Forest Management Plan (UFMP).
First of all, I very much appreciate that the City of Edmonds is pursuing an UFMP and the public
input that has been solicited in creating it. One of the reasons I moved to Edmonds was for its
lovely serene environment - one that is greatly enhanced by the City's trees! I've reviewed the
draft UFMP and agree with most of the points made. I would like to see the City set a goal of at
least maintaining the current percentage of canopy cover - as development increases we will
continue to see a decline in canopy cover unless additional steps are taken to preserve the
trees/canopy cover we currently have.
I do think the City of Edmonds can/should do more to protect trees on private property -
especially property that is in the process of being developed or redeveloped. There have
been several recent development projects in my neighborhood where the City said the developers
would do their best to preserve the trees - instead the lots were clear cut. Its easy for developers
to clear cut old trees and plant "replacement" trees; however this is not the best approach for our
neighborhoods, wildlife, or environment. "Replacing" second growth evergreens (50+ years old)
with small deciduous is not an equitable approach to our tree canopy or urban forest. I urge the
City to consider additional rules/restrictions to help preserve trees on privately owned property.
Thank you! I look forward to hearing more about this work and seeing the finalized Urban
Forest Management Plan.

Notes BY: P.B.

RE: UFMP [Urban Forest Management
Plan] April 7, 2018
PBL had volunteered to attend and feedback substance of Tree Board meeting on 4/5/18, which
featured a presentation of the DRAFT Urban Forest Management Plan under development for the
city by the consultant: Davey Resource Group [Ian Scott]. This writing reflects my notes from said
meeting/presentation with potential additional reference points for PB members in conjunction
with continuing reviews of the UFMP. Notes in no particular order or priority.
Board members should read both substance and commentary of the presentation
contained within My Edmonds News, posted April 5, 2018 [by Larry Vogel] for his more
detailed account of the presentation.
The procedures from here as to necessary revisions to the UFMP and any subsequent
substantive actions to be taken by the City appear to provide for a public review by the City
Council before any substantive revisions to the draft Plan are undertaken. This would mean
that the PB, after our scheduled review and discussion on April 11 and the public hearing
currently targeted for May 9 would take no final action' but could make comments and
recommendations on the draft Plan. (which might include any recommendations for
changes relative to subsequent City Council action). [Note that an additional public open
house is scheduled for April 19 at which further input from citizenry would be gathered].
These three input 'flows' [Tree Board review, Public open House, PB review/discussion]
would be compiled and forwarded to Council for their discussion and further input from
the public before any substantive revisions to the UFMP are undertaken by Davey.
(However, some corrections and clean-up to the background information may be done
ahead.) Process from that point forward would be determined later.
Specific comment/feedback points gleaned from the Tree Board meeting of April 5:
• Public comments received as to some shortfalls within DRAFT Plan data, specifically
➢ Tree species statistics applicable to Pacific NW appear to be lacking
➢ Plan refers to a 20 year process, but elsewhere refers to 'completion' as 2048
➢ Scientific data does not appear to be drawn from our area of the country,
particularly as to rainfall, tree species, diseases, and other environmental
data.
• Community 'responses' thus far [survey] only represent 175 responses —more
needed.
• Goals of both community and municipal participants should be to preserve
current 30.3% canopy citywide.
• DRAFT Plan identifies actions for which staff/dollar inputs would be needed.
For the City to implement Plan—amounts/projections will need to be carefully
considered.
• More discussion and direction needs to be undertaken to clarify both role of the
UFMP and any subsequent resultant Code revisions with respect to public
property trees vs. private property owners— citizens need to support UFMP
canopy maintenance goals for city, but plan should not dictate private property
rights.
• UFMP could incorporate guidance for potential future land development code
revisions to accommodate more effective land -clearing and tree preservation
criteria.
4. PBL is in process of collecting old historic photos on Edmonds hopefully illustrating early land
clearing and subsequent 'growth' of trees within the city —this would be to assist PB discussion

Comments on the Draft Urban Forest Master Plan (March 2018)
Ms. Shane Hope
Director of Development Services
City of Edmonds
My concerns about Tree Board and City of Edmonds moving forward are:
I thought that Tree Board would have as its mission to streamline some of process to comply with the
tree -related ordinances that City has. Instead of having to go from Person A to Person B to Person C,
streamline the process to have a Person A, known to be the Tree Authority for City, to answer any
questions that might arise. That's not what is happening and I am disappointed.
As a taxpayer, I am dismayed and appalled at the poor quality of work that the report contractor, Davey
Resource Group, is submitting for us to peruse or even read thoroughly. Much of the science that is
cited is based on studies in California. Many of the statistics cited in this report originate from
California. Has the writer or researcher of this expensive report walked around with a knowledgeable
arborist to see what trees grow well and are native to the area and take pictures if necessary? If the
Edmonds City Council approved an over six figure amount for this report, we are not getting our
money's worth!!
Trees are lovely. The big tall green conifers are one of many reasons we chose to move to Edmonds.
However, one would hope and desire practical uses and implementations of trees. Edmonds planted
street trees 20 years ago, but now homeowners are responsible for them, along with rigid guidelines
that are not clear, are hidden away, unless one asks many levels and layers of people. How is that the
best utilization of staff or trees?! How does that foster good will for citizens of the city?
Also the city plants or requires new homeowners or developers to plant trees in the sidewalk area.
Guess what? The sidewalks are buckling, the street sweeper must be employed and paid, and the street
sweeper truck must operate to pick up all of the leaves, the sidewalks must be grinded or replaced to
prevent falling by those of us who walk the streets of Edmonds for fun or business. Are all of the costs
and tedium worth the city's very rigid, costly agenda? Are all of those costs reflected in the Tree Plan?
Also if this new plan for trees encourages the coordination of at least three departments of the City's
workforce, why is it that only one area, Development Services, shows up for these public meetings? I
find that irregular, at best. If all three groups of the City workforce are to be held accountable, wouldn't
each group or entity want to show an interest or learn from the public what their concerns might be?

Hello Council Members,
There are certain points that do have to be addressed:-
1) Trees in the common areas that are the "showcase" for Edmonds that are planted on the
sidewalks and main streets. They provide beauty and shade and should be maintained by the
City and be under your area of domain. Some of them overgrow and homeowners do call the
City to ask for action.
2) Any new trees planted by the City on sidewalks, or otherwise, should be the appropriate tree for
the space.
3) Trees in areas not under the Edmonds Council control are: those trees in your citizens own
yards. You cannot mandate costs or rules for cutting them down (if too big or diseased, or incur
costs for replanting if required by home owners). These trees are not your business or your area
of control with fees or fines.
4) Hedges along sidewalks should be under your access with notifications should these hedges
overgrow into the sidewalk or grow higher than a 6' wooden fence. We have limited sidewalks
in this town, and to allow a homeowner to let their hedges (or large plants) impede sidewalks is
wrong.
5) We do not want a town where we are paying fines and under strict rules and regulations with
regard to our own homeowner trees. Many people plant the wrong trees that grow out of
control or are now too old to afford to apply for permits for cutting them down, have to pay a
fee for that, and then have to pay for an approved arborist to replant trees they don't need or
want in their yards. If the City is trying to pass these types of laws you will have a fiasco in the
City chambers soon.
6) The City already has rules on trees being protected if they grow by a stream (which we have
many in this town).
Thank you,

Dear Diane:
In the end, it was your penned e-mail address that endured, so here is my note in lieu of my
presence at the tree meeting on the 9th of May.
It appears that I've organized my notes according to the easel displays:
C-2 "outreach to arborists" is too weak. There needs to be something that you require of the
for the privilege of working in Edmonds (which will always decrease the canopy and so is a net
loss to our community). Perhaps they need to defend any tree -topping, which causes disease
and death of healthy trees, to the city arborist and then pay a special fee graduated according
to trunk diameter. They will pass this on to the homeowner, of course, but it will also be a
nuisance to them and they will be less likely to suggest it as an option.
The regulation needs to extend to lumberjacks, too, who have a saw and can climb a tree
but don't necessarily know the downside of their trade at all.
C-5 the Heritage tree program needs to involve the history and art groups of Edmonds and
should have a mapping on the Edmonds website, an app to tour the trees by sidewalk as well as
a paper map to hold as they do so (for those with that comfort zone). This program will utterly
fail if not thoroughly planned before it is implemented. And it will be worse than worthless
unless the trees are offered protection simultaneously with the status.
M-8 protecting canopy: 5-10 year plan is too short for trees. Soon you will have a bunch of 5-
10 year old trees and nothing else as all the rest are unprotected. Probably I miss the mark
here. but I'm right about the need for a longer view for NW trees that outlive us by generations.
Rotation of planning is important to consider. The iconic oaks at the fountain won't last
forever. Where are young oaks to be planted now to make sure we still have such shade in a
prominent place a generation or two from now? Variety of street trees by neighborhood gives a
sense of place as Seattle demonstrates. Variety and a planting schedule make for a lovelier
result.
Where pocket parks are designed (as on Dayton) be certain to consider shade trees. People
don't gravitate to cement in any season. We acknowledge global warming, so why not act like it
is coming.
This document ignores the view interests in Edmonds. That is the elephant in the room, but it
needs to be addressed head on. Every tree is in someone's potential "view", so without specific
regulation and zoning, we end up with a hot hardscape of a city with "views" of the sun in your
eyes.
This document ignores the aging- hippie desire to have solar -panels on your own roof (which
encourages you to cut your own trees and everybody else's). This is a city and the place for
solar panels is in a sunny field in Eastern Washington. I'm being facetious, but the reality of
these two questions has everything to do with any conversation about trees in Edmonds.
Respectfully,
Dawna Lahti

Edmonds City Council
121 5th Avenue North
Edmonds, WA 98020
Dear Councilmembers,
In response to Councilmember Buckshnis' request that residents voice opinions regarding the March
2018 draft Urban Forest Master Plan (UFMP), I submit this comment document to the Edmonds City
Council.
I have reviewed the draft UFMP, prepared by Davey Resource Group (Davey), from my perspective as an
Edmonds native and current resident, combined with 30 years of professional experience as a scientist
employed in environmental consulting across various states and internationally. The past 20 years of my
professional experience have been in the development, review, and management of environmental
impact analyses related to the National Environmental Policy Act. My review holds the draft UFMP to
the same standard as I expect from my draft Environmental Assessments and Environmental Impact
Statements: a scientifically objective document that informs decisionmakers in creating sound public
policy.
The Tree Board has adopted the slogan "Right Tree, Right Place" to summarize their objectives.
According to the draft UFMP, 87 percent of the current tree canopy is on private property, largely
outside of the City's control, making education a centerpiece of any successful urban forest
management strategy. If the City plans to turn the slogan into action, namely to help private landowners
answer the question "What is the right tree in this place?" and encourage them to plant and maintain
trees to serve that objective, it is essential to create a science -based UFMP that addresses benefits and
costs of trees within Edmonds. Unfortunately, the draft UFMP is stunning in its lack of a basic scientific
foundation, especially in the context of the unique characteristics of Edmonds.
Those of us who have had to opportunity to live in other regions of the country recognize the many
unique characteristics of the Puget Sound area as a whole, and Edmonds in particular. Some of those
characteristics are socio-geographic—our proximity to an urban area with world -class amenities and a
vibrant economy —while others relate to the caring and community -involved people who live here. But
it's the natural environment that separates us from many other cities. It's the water, the mountains, the
weather, the topography, and the trees. It is in tailoring the draft UFMP to these characteristics of
Edmonds that it fails —much of the draft UFMP feels like it was cut and pasted from a tree plan for a city
in California or Nevada.

Much of my review of the draft UFMP focuses on the Introduction, pages 7 through 14, which presents
the benefits of the urban forest. These benefits are key to developing the Urban Forest Asset Goals, the
management objectives of the urban forest, described beginning at page 57 of the draft UFMP. Each
management objective has a stated rationale, risk, and benefit that ties to the benefits described in the
Introduction. If science does not support the benefit, or if the benefit comes at great cost, then the
management objective must be reconsidered.
My comments follow. I appreciate the opportunity to comment on the draft UFMP.
Sincerely,
Ross Dimmick

Dimmick—Comments on Draft Urban Forest Master Plan, May 2, 2018 Page 1 1
Comment 1: The National Tree Benefit Calculator (www.treebenefits.com/calculator), used to determine
tree benefits shown in tables on pages 10, 11, 12, 13, and 14, is
1) more limited in its applicability than described in the draft UFMP,
2) far too inaccurate to produce meaningful results for a planning document, and
3) not transparent in its data sources and calculations.
The quantitative evaluation of benefits described in the Introduction (see tables on pages 10, 11, 12, 13,
and 14) is derived from the National Tree Benefit Calculator (http://www.treebenefits.com/calculator/),
co -designed by Davey Tree Expert Co. The calculator accepts four inputs: zip code, tree species, tree
diameter, and nearest land use (e.g., single-family residential, small commercial business). From these
four inputs, the calculator produces five different benefit values for a tree, corresponding to the draft
UFMP tables cited above: stormwater diversion, carbon (COA energy, air quality, and property value.
More limited in its applicability than described in the draft UFMP. In its descriptions and calculations of
tree benefits within the Introduction section, the draft UFMP confuses the three major categories of
trees in Edmonds that the plan is intended to address: city -owned street trees, trees in city -owned
parks, and trees on private property. On page 9, "Benefits of the Urban Forest," the draft UFMP states
"Individual tree owners can calculate the benefits of trees to their property by using the National Tree
Benefit Calculator (www.treebenefits.com/calculator) or with i-Tree Design
(www.itreetools.org/design)." The description at the website of the National Tree Benefit Calculator
states that the "tool is based on i-Tree's street tree assessment tool called STREETS." As the name would
suggest, i-Tree STREETS applies only to street trees, and is not designed to be applicable to "individual
tree owners." It is also not applicable to trees in city -owned parks. Therefore, the tables in the
Introduction apply to only a very small percentage of trees in Edmonds, street trees, likely comprising
well under 1 percent of the Edmonds tree canopy.
Far too inaccurate to produce meaningful results for a planning document. The calculator website itself
describes the calculations as "a first -order approximation." So, what does this mean? Edmonds is
included within a "Pacific Northwest" region, extending from the U.S./Canada border almost to
California, and from the Pacific Ocean to the Cascade Range. Entering the zip code from Aberdeen, with
more than double Edmonds' annual average rainfall, or Salem, Oregon, situated in the farmlands of the
Willamette Valley, produces exactly the same quantities and dollar values for a given tree. With the
differences among locations in this region, particularly climate, property values, and baseline air quality,
these values cannot be the same. For Davey to rely on such a crude tool for a paid report is
unacceptable. Davey needs to use the original documents that form the scientific basis for these
calculations and adapt them to the unique Edmonds setting, particularly precipitation frequency and
intensity, temperatures, baseline ambient air quality, and the mountain/water viewshed (a key
consideration in property value impacts).
Not transparent in its data sources and calculations. Central to any scientific document is the concept of
reproducibility —the reader should be able to achieve the same results by following the methodology
presented in the document and its references. On a high-school math test, this is called "show your
work." Davey's system does not provide verifiable sources or calculations of tree benefits. As such, it is
not possible to determine whether calculations are based on science that is relevant to our environment
in Edmonds, or even applicable to the question being asked.

Dimmick—Comments on Draft Urban Forest Master Plan, May 2, 2018 Page 12
Within my own work, I have been contracted on occasion to prepare documents to update existing
environmental impact analyses based on new information. It is frustrating (and expensive for the client)
when I have to reconstruct an analysis from scratch because the original author failed to adequately
document their calculations. For a UFMP to be useful for implementing a long-term strategy, it must
occasionally be updated to reflect:
• New science. Urban forestry is still a relatively new scientific field and strategies now being
implemented to manage urban forests will lead to new science on benefits and costs and case
studies on what works and what doesn't.
• Changes in development patterns. Edmonds continues to feel pressure from the heated Seattle
housing market, encouraging denser development in the form of apartments and townhouses.
• Changes in the natural environment. The draft UFMP's description of our current urban forest is
a snapshot in time that is ever -changing.
Because the draft UFMP poorly documents its methodologies and calculations, it will be difficult and
expensive for the City to update the UFMP to suit future needs. The City needs to ensure the
transparency of all analyses and reproducibility of data to allow for occasional updates of the plan and
to track progress against urban forest management goals.
Comment 2: The relationship between the urban forest and energy use, CO2, and carbon sequestration
are inadequately described and/or erroneously calculated.
Pages 11 and 12 of the draft UFMP claims that urban forests help reduce atmospheric greenhouse gases
through 1) sequestration of CO2 as wood and foliar biomass, and 2) lowering the demand for energy
used in heating and air conditioning, thereby reducing the emissions associated with electric power
generation and natural gas consumption. The draft UFMP claims that energy savings are achieved by:
shading dwellings and impervious surfaces; transpiration, the release of water vapor through tree
canopies causing atmospheric cooling; wind reduction, helping to avoiding winter heat loss; and green
roofs, putting native trees and vegetation on rooftops.
To test some of these statements, I used the i-Tree Design (www.itreetools.org/design) tool as
suggested in the draft UFMP. Somewhat randomly choosing a house on Alder Street between 6t" and 7tn
avenues, I used the design feature of the tool to place a single western red cedar, of 8-inch diameter at
breast height, in the front yard (south of the house). Other information about the house was
determined from a recent real-estate listing (constructed before 1950, no air conditioning) and entered
into i-Tree Design. The results related to CO2 and energy use over the next 20 years were stated by the
tool as follows:
$-44 of savings by reducing -2,463 lbs. of atmospheric carbon dioxide through CO2
sequestration and decreased energy production needs and emissions
• $0 of summer energy savings by direct shading and air cooling effect through evapotranspiration
• $-303 of winter energy savings by slowing down winds and reducing home heat loss
Note that the dollar savings and CO2 reduction values are negative. With the absence of air conditioning,
typical for houses in Edmonds, the effect of a single cedar tree was to increase energy use and,
correspondingly, CO2 generation by shading the house from sunlight in during the heating months of fall,
winter, and spring. According to the latest U.S. Census American Community Survey 5-year estimates,
Packet Pg. 65
Dimmick—Comments on Draft Urban Forest Master Plan, May 2, 2018 Page 13
6.A.b
approximately 57 percent of homes in Edmonds are heated by CO2-generating fossil fuels. Other tree
types and placements within i-Tree Design may produce more favorable results for the house analyzed
but are unlikely to show energy savings given our relatively mild winter climate and, typically, a lack of
air conditioning. But other tree placements may increase shading and energy consumption in
neighboring houses, which i-Tree Design does not model. This "neighbor effect" is particularly severe in
Edmonds —of the 1,001 communities in the U.S. larger than Edmonds (2016 U.S. Census Bureau
Estimates), only 5 are further north: Everett, Marysville, and Bellingham, Washington; Minot, North
Dakota; and Anchorage, Alaska. This means that the shadow cast by a tree in Edmonds, especially the
tall conifers native to this area, is long during the late fall and winter months, nearly 300 feet at noon for
a 100-foot-tall tree.
While it is true that the urban forest sequesters carbon through growth of biomass, the draft UFMP does
not address the fate of that carbon. Because urban trees are seldom used for wood products,
sequestered carbon is eventually returned to the atmosphere as part of the carbon cycle as trees die
and rot or are cut down and chipped or used as firewood. Theoretically, a mature urban forest will
release as much carbon as it takes in. This explanation provides needed context for the reader to better
understand the relationship of carbon sequestration and the urban forest.
Characteristics of Edmonds, particularly lack of air conditioning in most homes, low sun angles, and
abundant large conifers, cast doubt over claims that urban trees lead to net reduction in COz from
energy savings and carbon sequestration. The draft UFMP lacks any region -specific discussion of factors
that potentially affect its conclusions and its own modeling tool shows that net COz production and
energy use can increase in relatively common situations. It is inexcusable for the draft UFMP to omit
region -specific factors in drawing its conclusions and inappropriate to state any conclusions without a
thorough scientific analysis.
Comment 3: The costs of trees to the City are not adequately described nor calculated.
On page 34, the draft UFMP focuses its cost analysis on City expenditures for planting, maintenance, and
removal of trees, along with management and the cost of volunteer activities. The draft UFMP also lists
City departments and weekly estimated hours per week spent on urban forest -related activities. This
cost analysis appears to ignore other urban forest costs to the City. The following costs should be
quantified through interviews and data supplied by City staff, as well as the best available science:
• Assessment and repair of hardscape damage. A casual stroll around downtown Edmonds will
illustrate damage and repairs to sidewalks (Figures 1 and 2), gutters, and curbs from street
trees. Other damage may occur to stormwater drainage systems from tree roots.
• Street sweeping. Our wettest month, statistically, is November, when leaves shed from trees
reach their maximum. Also, our most severe windstorms tend to occur during the rainy months,
requiring the street sweeper to clean up leaves, boughs, and small limbs to maintain stormwater
drain performance.
• Catch basin and storm drain cleaning. Accumulation of leaves, needles, and other tree debris
can clog storm drains and require cleanout of catch basins.

Dimmick—Comments on Draft Urban Forest Master Plan, May 2, 2018 Page 15
There is a long list of other potential indirect costs, including:
• Carbon emissions. Pruning, tree removal, and street sweeping, among other activities, generate
carbon emissions from use of power equipment such as saws, chippers, trucks, and sweepers.
In determining net carbon value, the cost of these emissions must be included.
• Damage and injury from falling trees.
• Disruption to traffic during tree maintenance.
• Opportunity cost. The presence of trees precludes other potential uses of the space.
Recent scientific literature' addresses other potential costs, including utility company tree maintenance
and tree -related repair costs, which are passed on to ratepayers, as well as economic costs of power
interruption. The UFMP should list and evaluate whether these costs are relevant to Edmonds, and, if
so, should include them in the cost analysis.
Comment 4: The draft UFMP focuses only on urban forest management costs borne by the City. The cost
of trees to private landowners is all but ignored, despite representing 87 percent of the urban forest
canopy.
On page 34, the draft UFMP states: "Using the recent Urban Tree Canopy assessment as a benchmark
estimate, Edmonds' urban forest produces about $1,567,000 in environmental benefits and is
maintained with an annual budget of approximately $319,542." Subject to the caveats in my comments
regarding the accuracy of these numbers, this statement directly compares a benefit from the entire
tree canopy with the cost only to the City government. Obviously, the costs to private landowners for
maintaining their 87 percent of the canopy, including direct and indirect costs of pruning, leaf raking and
blowing, debris disposal, moss treatments, pressure washing, gutter cleaning, and hardscape repair, far
exceed the cost to the City. These activities also generate carbon emissions which need to be included in
the cost. If the draft UFMP intends to provide some sort of cost/benefit analysis, it needs to include the
costs to all parties.
Comment 5: Despite being shown as the largest environmental benefit (by dollar amount) provided by
the Edmonds tree canopy, the derivation of the stormwater management value remains an enigma.
On page 31, the draft UFMP states that the Edmonds tree canopy "Reduces 42.8 million gallons of
stormwater runoff, a benefit worth nearly $1.2 million." Note that this is 76 percent of the quantified
benefit for Edmonds. Two numbers are important to understanding this benefit: derivation of the value
of 42.8 million gallons of stormwater runoff diverted, and the cost per gallon assigned to that runoff,
approximately 2.8 cents. According to the draft UFMP, the 42.8 million gallons was derived from the
i-Tree Canopy model, which, in its web version, does not seem to produce estimates for stormwater
diverted. The complete input and output from this i-Tree Canopy model should be included as an
appendix for review.
During the April 19 Open House for the draft UFMP, I asked Ian Scott and Ian Lefcourte, both of Davey
Resource Group, how the 2.8 cents per gallon value for diverted stormwater was derived. Neither could

tell me, but Mr. Lefcourte said he would follow up on that information (the latest email I received from
Mr. Lefcourte said that he was checking with his geographic information system personnel). This value is
also used in the treebenefits.com model for calculating the benefits of individual trees, and in benefits
calculations in Table 2 of the draft UFMP. Through my own research, I found a value of 2.779 cents per
gallon in a report not cited in the draft UFMP (McPherson et al. 2002, Western Washington and Oregon
Community Tree Guide: Benefits, Costs and Strategic Planting); however, the reference cited by the
McPherson report as its source did not appear to support the value.
The difficulty in trying to track down how the largest quantified benefit in the draft UFMP was derived
should highlight a basic inadequacy with the document —its lack of transparency. Davey appears to be
asking us to take their word for it. All the documentation showing how these numbers are derived need
not be presented in the narrative of a plan that is intended for a non -technical audience, but it should be
included as an appendix to verify accuracy and to reduce the cost of future plan updates in response to
better data, changes in costs, and changes within the urban forest itself.
Comment 6: The canopy air quality benefit appears to ignore tree -generated pollen and volatile organic
compounds.
On page 31, the draft UFMP states that the Edmonds tree canopy "Improves air quality by removing
42.2 tons of pollutants (CO, NOz, Oa, SOz, and PMlo), valued at $146,823." 1 was unable to find any
accounting for the costs of pollens and biogenic volatile organic compound emissions (volatile organic
compounds generated by trees). Tree pollen levels are known to be high in this area, with visible
accumulations on cars and other surfaces, particularly in the spring. Pollen is known to have direct
health effects in this area, mostly as a nuisance either left untreated or treated with over-the-counter or
prescription medications; however, among some individuals, pollen can initiate an allergic reaction that
can, in turn, trigger asthma symptoms. The cost of both pollens and biogenic volatile organic compound
emissions should be included in the calculation.
Two additional questions should be answered within the air quality analysis in the draft UFMP: are air
quality values based on the mix of trees (particularly deciduous versus conifers) that we have in
Edmonds? What is the source of baseline air quality data used for Edmonds?
Comment 7: Mitigating the urban heat island effect is mentioned, but the draft UFMP presents no
information on the magnitude of the urban heat island in Edmonds, or whether one even exists.
At various places, the draft UFMP refers to trees mitigating the "urban heat island effect" through
shading of impervious surfaces; however the draft UFMP never presents data to establish whether
Edmonds even has a measurable urban heat island effect. On April 24, 2018, Seattle set a daily record
high temperature with 77°F recorded at SeaTac Airport. The high temperature recorded at the Port of
Edmonds weather station that day was only 60.5°F, more than 16°F cooler. With Edmonds' position at
the confluence of Puget Sound, Admiralty Inlet, and Possession Sound, the relatively cool temperature
of these water bodies in the summer, and the prevalence of an onshore flow, all of Edmonds, even along
the Highway 99 corridor, tends to be cooler in the summer, sometimes much cooler, than communities
located further away from the water or in the South Sound. The draft UFMP should either eliminate any
mention of urban heat island effect or present data defining the magnitude of the urban heat island
effect for Edmonds and science determining that mitigating the effect would have a net environmental
benefit (e.g., not increase COz emissions through increased fall/winter/spring heating needs).

6.A.b
Dimmick—Comments on Draft Urban Forest Master Plan, May 2, 2018 Page 17
Comment 8: To be useful in achieving its goal of enhancing wildlife habitat, the UFMP must list which
wildlife species need habitat to ensure that cultivating the correct types of trees is encouraged.
Wildlife habitat is mentioned numerous times as a benefit of the urban forest, but there is no list of
target wildlife species the City is attempting to provide habitat for. Without this list, a particular tree
may or may not provide suitable habitat. Some species have experienced population decline because
their habitat requirements are too specific. On page 9, the draft UFMP states "there is a widely accepted
guiding rule in tree resource management that no single species should represent greater than 10% of
the total population, and no single genus more than 20%." The UFMP needs to present a list of target
wildlife species and explain how the diverse forest goals help rather than hinder these species.
On pages 7, 14, 18, and 28, the draft UFMP mentions that trees provide "critical habitat" for wildlife.
The term "critical habitat" has a specific regulatory meaning under the Endangered Species Act. Is that
the intended meaning here? If so, for which wildlife species is the Edmonds urban forest considered
critical habitat?
Comment 9: Apparent math discrepancy.
On page 25 of the draft UFMP are the statements "The City of Edmonds includes 47 parks covering 344
acres (5.6% of all land area) (Map 3). Edmonds' parks have an average tree canopy cover of 44.1%." This
would indicate that park canopy covers 151.7 acres (344 acres x 0.441), yet the canopy cover of just the
five largest parks (Table 7, page 26) is 210 acres.

Chris Walton — He said he was totally in favor of supporting any aspect that related to trees. He said
he had many questions when reading the report: 1) there was some analyses of a 6% reduction in
canopy and it was unclear as to how that happened? 2) There was public trees of 12% and private
land of 88% on private land and could not understand how the report only addressed the 12% of trees
on public land? 3) There was a goal to increase canopy from 30% to 50% and yet it doesn't correlate
with the 6% reduction comment as well as only focusing on the 12% of Tree canopy. He wanted to
know how to increase tree canopy on both public and private land.
Gary Nelson - He enjoyed the graphics of the report but that there were many errors in the report: one
timeline error concluded in 2048? P 7 says Edmonds is oldest City in Snohomish Cty and he
questioned that fact. One table lists the prominent specifies of trees in Edmonds and he didn't think list
was long enough. Talked of GMA guidelines and private property rights. James Clarke has named
misspelled. Priority of planting and blockage of views is a big issue and report didn't seem to touch
upon this factor. P 37 gave a long list of pests but nothing prominent to Edmonds — anyone could have
provided that list. Survey — it's clear that 40% from Bowl (view) area answered the questions and these
people want control of the trees and protection of views.
Ross Dimmick — He is a scientist and writes EIS statements for a living and likes to focus on "purpose
and need" and "what and why". From a scientific perspective, this report is a disaster as example, it
refers to USFS region of HI and CA and the intercepting rainfall was in accurate as was the increased
soil capacity. The fundamental science was quite disappointing from this report.
Wendy Wisdom — Report needs a lot of work in the area of habitat and wildlife and that snag trees are
very important to the that eco system.
Dawna Lahti — She had not finished report but found that the report did not have a vision. The goals
were not clear in terms of private or public property or the issues of snags or corridors.

o Barbara is working with Debra Dill (City) on the Summer Market Tree Give Away.
o Gail and Frank are working are working on Edmonds in Bloom Tree Identification.
UFMP presentation by Ian Scott of Davev Resource Group (Power Point Presentation Part of notes
o Please refer to the entire Power Point Presentation for the full breakdown of overview, structure,
principals of adaptive management and goals. Each slide was highlighted with the main themes
being that the City is reactive rather than proactive. The City doesn't know the condition or
inventory of the urban forest. Comments were later made that some felt the City Staff did have a
pretty good understanding of the street trees and tree inventory. Davey's rebuttal was that it is not
documented.
o Examples of the City Resources were provided as well as city resources utilized. Comments were
brought forth regarding questioning this table and Davey's rebuttal was that the information was
given by staff personnel and only identified Administration and now volunteer groups.
o Survey was reviewed of which the data showed: 40% from Edmonds Bowl; 15% from Seaview
area (view area) and 29% from other neighborhoods and consensus was city is in reactive
management mode and regulations on private property should be limited. Comment was made
that the survey was skewered because it is based on over 50% of the population is in view area.
o Goals were then provided on How to get to the 50% canopy or to sustain a no new loss in canopy
and that City needs to move toward proactive management. City should establish a departmental
working team that could document trees and work towards work plans that have adaptive
management. Community goads were also given to assist in moving towards tree sustainability
and adaptive management.
o Next Steps came forth with meetings and public hearing at Planning Board then revisions and then
update to Council. Council Member Buckshnis requested that the Council be part of the "draft
revision stage" so that Council can provide the necessary input to the draft and that it would not fall
on the planning board.
QUESTIONS and Comments:
• Tree Board Commissioner Phipps - How did the plan come up with planting 700 trees a year. Davey's
Group said that was an example of a number to be used so to complete a no -net loss concept. Phipps
than stated that it seemed that this goal needs to go beyond the inventory of public trees.
• Chair Petersen — Stated that the report needs a lot of work and that the "tree" solution for public
property and private property seem different and that the models should reflect a solution for the entire
canopy.
• Tree Board Commissioner Chase — Stated that there should be a list of preferred trees and deal with
the goals of diversity. Some trees are more resilient and the report didn't really address the diseases
and the trees affected.
• Tree Board Commissioner Phipps asked to look at the priority of planting slides and said that the
majority of red area on the map was right below 9t" avenue which is in the area of views and that it
would appear to be fragmented and no one in Edmonds would want big trees below 91" Avenue.
Packet Pg. 74
6.A.c
Vice Chair Caruso (who has his doctorate in plant pathology) indicated that the report needs to provide
specific pest to the Edmonds region and he named a few that should be highlighted. He also said that
the conifers were not really discussed and he agreed with Ms. Chase that there needs to be more
distinction and diversity in the report.
Tree Board Commissioner Phipps brought up that there was not recommendations or discussion
regarding a Tree Ordinance and that the report merely cited all the areas in the code that related to
trees. Davey's Group stated that it was not the intent of the report to advise on any code and that Best
Available Science would be of use for any code.
Chair Peterson brought forth an email question regarding the cutting down of very old evergreens and
replacing them with flowering trees and that cutting down a Douglas Fir and replacing it with a
deciduous tree is not even addressed in the report. It was also commented that developers are just
clear cutting a lot and building. Davey's Group responded that clear cutting and retaining trees is a
Development Code issue and not a function for this report. He did say it is important to keep in mind
"how much canopy is at risk" and what are mortality rates and this all needs to be documented in a
proactive manner.
Tree Board Commissioner Olsen brought up the issue of the California Redwoods and that the City
needs to be cognizant as to where to place these trees that grown majestically and can be hundreds of
feet high.
New Business
• Logo and Banner. Discussed and looked at material for banner and then discussed a runner and table
cloth. Moved by Vivian and seconded by Frank to spend up to $400 for the banner (3x3 square) and table
runner.
• Suzanne provided a three -fold brochure of an example "small trees" and/or "trees in small places". She
was asked to send that to Diane and she will have the City try and convert it to a word doc or pdf for Tree
Board Members to review.

Executive Summary
Scope & Purpose
The purpose of the Urban Forest Management Plan
(UFMP)istoprovide aguide for managing, enhancing,
and growing trees in the City of Edmonds over the
next 20 years. The plan also includes long-range
goals to promote sustainability, species diversity,
and greater canopy cover. Publicly -managed trees
along streets, in parks, and at City facilities are
collectively referred to as the community urban
forest. Privately owned trees are also considered
part of the urban forest in this plan because of their
function and contribution to the sustainability of the
overall urban forest in Edmonds; however, the City
recognizes that it has a limited role in the care of
private trees.
Recognizing the significance of environmental and
socioeconomic benefits provided by trees and their
relationship with a high quality of life, the UFMP
aims to:
Illustrate the value and benefits of trees.
Promote shared vision and collaboration
between community residents.
Establish benchmarks and metrics
to monitor the long-term success of
management strategies.
Enhance the health and sustainability of the
community urban forest.
Increase the vital benefits that the trees
provide to Edmonds and the region.
• Ensure that resources are in place to
support the care and management of the
community's trees.
E.- W., - I
This UFMP includes goals and action strategies for
the long-term and short-term in support of this
purpose. It identifies appropriate resources to
adequately manage community trees. It is intended
to remain flexible and dynamic, allowing for the
exploration and implementation of the actions as
funding and resources permit.
The development of the UFMP included a
comprehensive review of existing policies and
regulations, currentfunding and maintenance levels,
analysis of the extent, condition, and composition
of the existing tree resources, stakeholder concerns,
and community input.
Plan Foundation
Spending any amount of time outdoors in the Citywill
reveal the abundant and diverse natural resources
that surround the residences and businesses in
Edmonds. Besides the obvious amenities available
to a city on the coastline of the Puget Sound,
another abundant natural wonder in Edmonds is
its trees. Interspersed amongst the buildings and
roads, trees provide the City with the shade, fresh
air, and softened landscape that help people achieve
the unique experience referred to as; "an Edmonds
kind of day." All of the trees in Edmonds make up
the City's urban forest tree resource. Without active
management, this urban forest is at risk.
In December 2016, the City adopted a Comprehensive
Plan that formally recognized that the community
places a high value on the conservation of the urban
forest. This Urban Forest Management Plan (UFMP)
is intended to be an element that aligns in support
of the Comprehensive Plan. In particular, this UFMP
aligns with the intentions of, "providing a framework
for moving the Edmonds community toward a
sustainable future that integrates and responds
to environmental, economic, and social needs in a
1 scope & Purpose
Packet Pg. 84
6.A.e
way which meets the needs of the present without
compromising the ability of future generations to
meet their own needs" (Comp Plan, 2016).
The following principlesforurban forest management
set the framework for the UFMP:
• Optimize the ecosystem services provided
by trees.
• Control tree maintenance costs to the com-
munity.
• Create pathways to stable and predictable
funding.
• Mitigate risks and liabilities associated with
trees.
The structure and organization of the UFMP are
based on the understanding of what we have, what
we want, how we get there, and how we are doing.
This structure, referred to as adaptive management,
is commonly used for resource planning and
management (Miller, R.W.,1988) and provides a good
conceptual framework for managing community
forest resources.
The plan development process involved a
comprehensive review and assessment of the
existing community tree resource, including
composition, value, and environmental benefits.
The process explored community values, existing
regulations, and policies that protect community
trees. In addition, there were multiple stakeholders,
internal and external, who played a role in the
planning, design, care, and advocacy around the
community forest. These stakeholders include the
general public, City departments, the Citizens' Tree
Board, and Snohomish Public Utility District (PUD).
Each of these stakeholders contributed to the
development of this Plan.

What Do We Have?
Edmonds was founded along the coast of the Puget
Sound in 1890. Similar to the rest of the region,
Edmonds had forestlands that were logged and
waters that were fished. As Edmonds has grown
in population, the forest has been urbanized
and divided for parks, homes, and businesses.
Recognizing the role of trees in the community and
the necessity to manage them, the City drafted a
Streetscape Plan in 2002 that included tree planting
guidelines as part of the general aesthetic goals for
the community. Revised in 2006 and again in 2015,
elements of this Plan introduced tree care policy
that has since been the source for many of the City's
tree management decisions.
In terms of regulations, the care for the urban forest
is generally understood to be required by the Growth
Management Act of 1990. Guidance is provided by
the City's Comprehensive Plan (2016), the Parks,
Recreation and Open Space Plan (2016), and the
Streetscape Plan (2015). These primary documents
define the reach of existing regulations and policies
within which care for the urban forest is mandated:
Comprehensive Plan (2016) - Environmental
Quality Goal A - "...Protect environmental
quality within the Edmonds community
through the enforcement of community -
based environmental regulations."
• Parks, Recreation and Open Space Plan
(2016) - Natural Resource and Habitat
Conservation Goal 4 — "Preserve and
provide access to natural resource lands
for habitat conservation, recreation, and
environmental education."
• Objective 4.5 - Expand the urban forest
and increase tree canopy in Edmonds.
• Action Plan 4.G - Steward the urban
forest using appropriate maintenance
of street and park trees, clear removal
and replacement policies and providing
information about urban forestry to
property owners.
Streettcape Plan (Revised 2015) - Celebrate
Sustainable Practices. In redesigning
the corridor, it is critical that the new
interventions improve the street's
performance. This includes enhancing
the street environment and gateways for
pedestrian benefits through an Urban
Forestry program in the Downtown/
Waterfront area.
The urban forest is a combination of both public
and private trees. Any trees that the City has direct
control of and responsibility for are defined as
the community tree resource. This includes public
trees in parks, along rights -of -way, and around
City facilities. Managing any resource begins with
defining what is being managed and establishing
benchmarks along with clearly defined goals and
expectations. While public trees along major
arterials and high -profile areas are well-known and
routinely cared for by City staff, other public street
trees are expected to be maintained by the adjacent
property owner. Aside from individual development
applications, the City does not have a method to take
an inventory or track the history, status, or location
of public trees. In addition, providing adequate care
for trees requires a level of knowledge and a skill set
that many property owners do not have.
The planning process for this UFMP included an
assessment of tree canopy. The results of the study
provide a clear picture of the extent and distribution
of tree canopy across Edmonds, benchmarking the
average tree canopy cover at 30.3%. Analysis of
historical change estimates that the City has lost 114
acres of its tree canopy since 2005. In 2005, there
was an average tree canopy cover of 32.3%.
The primary challenges and opportunities for urban
forest management are:
Private owners control the majority of tree
canopy (83.0%) with few regulations to limit
tree removal.
There is limited knowledge about the
condition of trees in the urban forest.
• There is an estimated 1,619 acres of priority
tree planting space to expand the urban
forest canopy.

What Do We Want� on trees as problems are discovered, but they also
• look for opportunities to plant trees in strategic
public places.
The plan development process included substantial
outreach to public stakeholders, residents, and
non-profit agencies. The process provided a broad
perspective of the challenges that face Edmonds'
urban forest. Through open house forums and
public meetings, the City has found an engaged
set of residents with varying opinions on matters
pertaining to the care of the urban forest.
City Staff were also consulted during plan
development, with City code and public safety
being the main considerations when making tree
care decisions. City Staff will often take a reactive
approach to tree management by performing work
In general, stakeholders from both the community
and City Staff share the following desired outcomes
for the UFMP:
• Preservation and Enhancement of Tree
Canopy
• Sustainability, Health, and Safety of the
Community Tree Resource
• Preservation and Enrichment of Wildlife and
Habitat
• Increased Outreach and Education
• Increased Collaboration with Volunteers and
Non-profit Groups

How Do We Get
There?
The long-range strategic goals provided in this Plan
are proposed to address the three components of a
sustainable urban forestry program:
• Urban Forest Asset Goals - which are
intended to improve the urban forest re-
source over the next 20 years by developing
detailed expectations for the urban forest.
• Municipal Resource Goals - which are
intended to drive improvements in City
policy and practices by developing efficiency
and alignment of efforts within City depart-
ments.
• Community Resource Goals - which are
intended to build stronger community en-
gagement and public participation in urban
forest stewardship.
How Are We Doing?
The UFMP presents opportunities to care for the
urban forest in Edmonds by providing an overarching
framework for urban forestry operations, policies,
and programs. It presents a high-level review of
urban forest management in the City, including
historical context and an exploration of the benefits
of Edmonds' trees. Building upon that information,
the Plan connects the community's vision for the
urban forest with appropriate goals and actions.
This Plan provides various goals to pursue along a
20-year timeline concluding in 2038. These short
and long-term goals will be achieved by adapting
the Plan according to a five-year cyclical review of
operational objectives. The success of the UFMP
will be measured through the realization of goals
and will be demonstrated through increased value
of the urban forest and increased environmental
benefits. Ultimately, it will lead to an enhancement
of tree canopy throughout the City. Furthermore,
the greatest measurement of success for the UFMP
will be how successful it is in meeting community
expectations for the care and preservation of the
community tree resource.

Packet Pg. 89
6.A.e
Introduction
Trees play an essential role in the community
of Edmonds, providing numerous tangible and
intangible benefits to residents, visitors, neighboring
communities, and wildlife. Research demonstrates
that healthy urban trees can improve the local
environment and lessen the impact resulting from
urbanization and industry (UEP, 2017). Trees improve
air quality, reduce energy consumption, help manage
stormwater, reduce erosion, provide critical habitat
for wildlife, and promote a connection with nature.
In addition to these direct improvements, healthy
urban trees increase the overall attractiveness of a
community. In Portland, Oregon, street trees were
found to add an average of $8,870 to homes' sales
price as well as reduce time on the market for home
sales by 1.7 days (Donovan et al., 2010). Studies
on the business benefits of trees have shown how
retail districts promote longer and more frequent
shopping and greater sales (Wolf, 2007). Urban
trees support a more livable community, fostering
psychological health and providing residents with a
greatersense of place (Kuo, 2003). Communitytrees,
both public and private, soften the urban hardscape
by providing a green sanctuary and making the City
of Edmonds a more enjoyable place to live, work,
and play. The City has emphasized the importance
of trees within the Comprehensive Plan (2016), so
much so that public trees are defined as a valued
community resource, a critical component of the
urban infrastructure, and a part of the City's identity.
Community
Edmonds was founded in Snohomish County
along the coastline of the Puget Sound in 1890.
Early settlements were built in the City to access
natural resources, where shingle mills became the
primary industry. Although construction of the
Great Northern Railway along the waterfront was
expected to be the main source of growth in the
City, most growth occurred due to its proximity to
Seattle. Passenger ferry service has also helped the
town grow and prosper.
Edmonds' population, from 2017 State estimates, is
41,260 people and covers a land area of 8.9 square
miles. It is the third largest city in the county after
Everett and Marysville. By 2035, the population is
expected to be 45,550.
Community Vision for the UFMP
Edmonds' Comprehensive Plan provides a vision of
the City as an attractive, sustainable community for
all ages. It specifically recognizes the value of trees
as contributing to that vision and directs that an
urban forest management plan be used as a guide
for decisions on managing the forest resource,
especially focusing on public land and rights -of -way.
For private lands, the UFMP would guide education
and incentives to encourage good tree management
practices.

Benefits and
Challenges of the
Urban Forest
Urban and natural forests work constantly to mitigate
the effects of urbanization and development, which
protects and enhances lives within the community.
This is increasingly evident as communities calculate
the benefits of their urban forest using a complete
inventory or sample data in conjunction with the
USDA Forest Service i-Tree software tools. This state-
of-the-art, peer -reviewed software suite considers
regional environmental data and costs to quantify
the ecosystem services unique to a given urban
forest resource.
Individual tree owners can calculate the benefits
of trees to their property by using the National
Tree Benefit Calculator (www.treebenefits.com/
calculator) or with i-Tree Design. (www.itreetools.
org/design). The National Tree Benefit Calculator
was developed by Casey Trees and Davey Tree
Expert Company to aid in the understanding of the
environmental and economic value trees provide
on an annual basis. In general, there are five (5)
important ways in which trees provide benefits:
Water Quality, Carbon Sequestration, Energy
Savings, Air Quality, and Socioeconomic benefits.
Water Quality
Urban stormwater runoff is a major source of
contamination for the Puget Sound and riparian
areas throughout Edmonds, threatening both human
health and wildlife, including salmon populations.
Requirements for surface water management
are becoming more stringent and costly for both
developers and the City.
By incorporating the right mix of urban trees into
stormwater management planning, runoff volumes,
peak stream flows and flooding incidents may all
be reduced; a strategy that may lessen the need for
constructing stormwater management facilities and
the cost of treatment to remove sediment and other
pollutants.
Trees improve and protect water quality by:
• Intercepting Rainfall — Trees intercept
rainfall in their canopy, which act as a mini -
reservoir. Some water evaporates from the
canopy and some slowly soaks into the
ground, reducing the total amount of runoff
(Xiao, et al., 2000). Canopy interception
also lessens soil compaction, which in turn
further reduces runoff.
• Increasing soil capacity and infiltration —
Root growth and decomposition increase
the capacity and rate of soil infiltration
by rainfall and snowmelt resulting in
slower percolation rates and increasing
the filtration of contaminants (Xiao, et al.,
2007).
• Reducing soil erosion — Tree roots reduce
the flow and volume of stormwater runoff,
avoiding erosion and preventing sediments
and other pollutants from entering streams,
rivers, Lake Washington, and the Puget
Sound (WA Department of Ecology, 2011).
• Providing salmon habitat — Shade from
trees helps to cool warm urban runoff,
which poses a threat to anadromous fish,
like salmon. Shade from trees provides
lakeside and riparian habitat for salmon
and cools water temperatures, increasing

salmon survival (Puget Sound Partnership,
2012).
In Edmonds, a mature (8" DBH) Bowhall Maple
growing along a residential street would intercept
an estimated 477 gallons of stormwater from city
storm sewers in 2017 avoiding $13.25 in stormwater
management cost (www.treebenefits.com, 2017).
Among the signature trees of the Edmonds
streetscape plan (2015), chanticleer pear intercepts
the most stormwater runoff (509 gallons valued
at $14.16) per tree. Japanese stewartia intercepts
the least stormwater runoff (153 gallons valued at
$4.26) per tree.

Carbon Sequestration
As environmental awareness continues to increase,
governments are paying particular attention to global
warming and the effects of greenhouse gas (GHG)
emissions. As energy from the sun (sunlight) strikes
the Earth's surface it is reflected back into space as
infrared radiation (heat). Greenhouse gases absorb
some of this infrared radiation and trap this heat in
the atmosphere, increasing the temperature of the
Earth's surface. Many chemical compounds in the
Earth's atmosphere act as GHGs, including methane
(CHj, nitrous oxide (N,O), carbon dioxide (CO),
water vapor, and human -made gases/aerosols. As
GHGs increase, the amount of energy radiated back
into space is reduced, and more heat is trapped in the
atmosphere. An increase in the average temperature
of the earth may result in changes in weather, sea
levels, and land -use patterns, commonly referred
to as "climate change." In the last 150 years, since
large-scale industrialization began, the levels of
some GHGs, including COz, have increased by 25%
(U.S. Energy Information Administration).
Trees absorb atmospheric carbon, which reduces
greenhouse gases. The carbon -related function of
trees is measured in two ways: storage (total stored
in tree biomass) and sequestration (the absorption
rate per year) (Jo, et al., 1995). Urban trees reduce
atmospheric carbon dioxide (CO) in two ways:
Directly —Through growth and the seques-
tration of CO2 as wood and foliar biomass.
Indirectly — By lowering the demand for
heating and air conditioning, thereby reduc-
ing the emissions associated with electric
power generation and natural gas consump-
tion.
In Edmonds, a mature (8" DBH) Bowhall maple
growing along a residential street would annually
reduce over 148pounds ofatmospheric carbon (www.
treebenefits.com, 2017). This can be represented as
about $0.46 in benefits both in carbon sequestered,
and avoided. Among the signature trees of the
Edmonds streetscape plan (2015), Japanes stewartia
reduces the most atmospheric pounds of carbon
(195 pounds valued at $0.62) per tree. Chanticleer
pear reduces the least atmospheric carbon (148
pounds valued at $0.48) per tree.

Energy Savings
Electric and gas utilities develop energy conservation
solutions to keep rates low for their customers,
reduce their need to build new lines, and, ultimately,
to be good environmental stewards. Energy services
delivered to Edmonds residents are provided by
Snohomish Public Utility District (SNOPUD). This
organization recognizes how trees can reduce
energy consumption and encourage Edmond
residents to consider trees as a cooperative strategy
for improving energy conservation (SNOPUD, 2017).
Urban trees and forests modify the environment
and conserve energy in four principal ways:
• Shade dwellings and impervious
surfaces — Impervious surfaces in 2011
were assessed as 34% of the total land
base (Edmonds, 2017). Shade from trees
reduces the amount of radiant energy
absorbed and stored by these impervious
surfaces, thereby reducing the urban heat
island effect, a term that describes the
increase in urban temperatures in relation
to surrounding locations (Simpson &
McPherson, 2000). Shade from trees also
reduces the amount of energy used to cool
a structure (Simpson, 2002).

• Transpiration —Transpiration releases
water vapor from tree canopies, which
cools the surrounding area. Through
shade and transpiration, trees and other
vegetation within an urban setting modify
the environment and reduce heat island
effects. Temperature differences of more
than 9°F (5°C) have been observed between
city centers without adequate canopy cover
and more forested suburban areas (Akbari,
et al., 1997).
• Wind reduction — Trees reduce wind speeds
by up to 50% and influence the movement
of air and pollutants along streets and
out of urban canyons. By reducing air
movement into buildings and against
conductive surfaces (e.g., glass, metal
siding), trees reduce conductive heat loss,
translating into potential annual heating
savings of 25% (Heisler, 1986).
• Green Roofs — Native trees and vegetation
on rooftops can help reduce the urban
heat island effect, decrease the heat loss
through rooftops and provide a beautiful
addition, not only for enjoyment to humans,
but also contribute to the success of the
community's ecosystem by increasing
habitat for all living creatures (Department
of Energy, 2004).

Air Quality
Urban trees improve air quality in five fundamental
ways:
• Reducing particulate matter (e.g., dust and
smoke)
• Absorbing gaseous pollutants
• Shade and transpiration
• Reducing power plant emissions
• Increasing oxygen levels
They protect and improve air quality by intercepting
particulate matter (PM,,,), including dust, ash, pollen,
and smoke. The particulates are filtered and held in
the tree canopy where they are eventually washed
harmlessly to the ground. Trees and forests absorb
harmful gaseous pollutants like ozone (0), nitrogen
dioxide (NO), and sulfur dioxide (SO). Shade and
transpiration reduces the formation of 03, which
is created during higher temperatures. Scientists
are now finding that some trees may absorb more
volatile organic compounds (VOC's) than previously
thought (Karl, T. et al 2010; Science NOW, 2010).
VOC's are a class of carbon -based particles emitted
from automobile exhaust, lawnmowers, and other
human activities.
By reducing energy needs, trees also reduce
emissions from the generation of power. And,
through photosynthesis, trees and forests increase
oxygen levels.

Aesthetic, Habitat,
Socioeconomic, and Health
Benefits
While perhaps the most difficult to quantify,
the aesthetic and socioeconomic benefits from
trees may be among their greatest contributions,
including:
• Beautification, comfort, and aesthetics
• Shade and privacy
• Wildlife habitat
• Opportunities for recreation
• Reduction in violent crime
• Creation of a sense of place and history
• Human health
• Reduced illness and reliance on medication
and quicker recovery from injury or illness
Some of these benefits are captured as a percentage
of property values, through higher sales prices
where individual trees and forests are located.
While some of the benefits of forests are intangible
and/or difficult to quantify (e.g., the impacts on
physical and psychological health, crime, and
violence), empirical evidence of these benefits does
exist (Kaplan, 1989; Ulrich, 1986; Kuo & Sullivan ,
2011). However, there is limited knowledge about
the physical processes at work, and their interactions
make quantification imprecise. Exposure to nature,
including trees, has a healthy impact on humans
(especially children), such as increased worker
productivity, higher test scores, reduced symptoms
of ADD, and faster recovery times following surgery
(Faber et al., 2006).
In addition, trees and forests have positive economic
benefits for retailers. There is documented evidence
that trees promote better business by stimulating
more frequent and extended shopping and a
willingness to pay more for goods and parking (Wolf,
2007).
Trees further generate socioeconomic and health
benefits by generating better school performance,
less workplace illness, increased concentration, all
of which yield an increase to overall productivity. In
addition, the trees throughout the built environment
(and especially among vacant lot conversions and
streets) promote active living connectors and reduce
crime rates. Thus, trees provide for their community
by generating new economic income and removing
judicial system costs (Wolf, 1998).
In addition, trees and forestlands provide critical
habitat (foraging, nesting, spawning, etc.) for
mammals, birds, and fish and other aquatic species,
along with limitless opportunities for recreation,
offering a healthful respite from the pressures of
work and everyday stress.

Challenges
Developing and caring for a healthy urban forest
requires the coordination of many different
stakeholders, with a clear vision, and dedicated
resources. As such, the urban forest intersects with
many other elements of the city. This can result in
conflict or challenges including:
Conflicts with Buildings and Infrastructure
- Tree canopy of a small -forested area that is
surrounded by non -forested land cover.
Hazard Trees - Trees can create hazards to
the community. Storm events, accidents,
improper maintenance, and the natural
death of trees can all create structural
weaknesses for trees and the surrounding
area.
• View Issues - Edmonds is known for the
majestic views of the Puget Sound. It is
possible for trees to block these views if
they grow too large or were planted in
improper locations.
• Maintenance - Trees are living
infrastructure. As such, they require active
and regular maintenance. Structural
pruning, irrigation, and the management
of pests and diseases are some critical
maintenance practices that must occur to
ensure a healthy and vibrant urban forest.
Choice of Tree Species - Different tree
species have different needs, growth
patterns, and resistances to pests and
diseases. A diverse palette of species
improves the resilience of the urban forest.

What Do We Have.?
To effectively manage the urban forest, it's essential
to have knowledge and understanding of what exists
today. This section lays the groundwork for the
UFMP with historical context, current policies and
practices and understanding about the existing state
of the urban forest.
History of Urban
Forestry in Edmonds
Trees have been an important part of the City's
character and economy since its founding. However,
to understand and manage the urban forest has
depended upon whichtreesare beingconsidered and
where the trees were located. This is evident from
the various locations where trees are referenced in
the City code as well as the variety of departments
whose staff oversee tree related matters. Edmonds
had been designated by the National Arbor Day
Foundation as a Tree City USA since 2011, but has
had city staff in different departments managing
tree issues within the City for decades.
Recognizing the role of trees in the community and
the necessity to manage them, the City drafted a
Streetscape plan in 2002 that included tree planting
guidelines as part of the general aesthetic goals of
the community. Revised again in 2006 and 2015,
elements of this plan introduced tree care policy
which has been the source for much of the City's
tree management decisions ever since.
In 2010, the City formed the Edmonds Citizens'
Tree Board to assist in the development of tree
ordinances and to encourage the planting and
maintaining of trees. This is an early example of
the City taking steps towards management of tree
resources as an integrated ecosystem of both public
and private trees. In 2015, one of the efforts of this
board was a proposal to the City for updated tree -
related municipal ordinances. These proposed tree
codes, through a public comment period, were
rejected in part due to public concerns about private
property rights, but also because the City felt that it
had insufficient tree policy direction to warrant the
recommended codes.
From these related events, it's clear that the
community has assumed an increasing level of care
for the urban forest that would benefit from long-
term strategic planning. Increasing regulations from
the State and Federal Government for environmental
stewardship requirements have also played a
significant role in defining the level of care for the
urban forest that exist in Edmonds today.
Of special note are three policy sources that directly
influence the management of urban forestry
and land use in Edmonds; The Washington State
Growth Management Act (1990), the Edmonds
Comprehensive Plan (2016), and the Edmonds Parks
Recreation and Open Space (PROS) Plan (2016) (The
PROS Plan is also an element of the Comprehensive
Plan.) Their backgrounds, roles, and influences on
the development and operation of Edmonds urban
forest are discussed below.
17 what Do we Have?

6.A.e
Growth Management Act (1990)
In 1990, the State Legislature adopted the
Washington State Growth Management Act (Chapter
36.70A RCW) on the basis that uncoordinated
and unplanned growth posed a threat to the
environment, sustainable economic development
and the overall quality of life in Washington. Unique
among states, the Act requires that municipalities
prepare their own comprehensive plans that provide
for growth and development in a manner that is
locally and regionally consistent, achievable, and
affordable. All cities and counties in Washington are
required to adopt critical areas regulations by the
Growth Management Act (GMA). The GMA defines
critical areas as:
"Critical areas" include the following areas and
ecosystems:
a. Wetlands;
b. Areas with a critical recharging effect on
aquifers used for potable water;
c. Fish and wildlife habitat conservation areas;
d. Frequently flooded areas; and
e. Geologically hazardous areas.
PLACEHOLDER:
Picture
Cities are required to include the best available
science in developing policies and regulations to
protect the functions and values of critical areas.
Further to that end, jurisdictions must review,
evaluate, and, if necessary, revise their critical areas
ordinances per an update schedule.
Edmonds has an outstanding inventory of critical
areas and protection of these critical areas overlaps
with the protection of the urban forest. The trees
in the urban forest increase soil security to protect
wetlands, waterways and flooded areas, and the
branches and canopy provide ample real estate for
wildlife to call home. It is important that the City
plan for all the trees in the urban forest as a whole,
not just critical areas.
This notion is reinforced in Washington
Administrative Code (365-190-060(1)) which
specifies when classifying forest land resources that
"Cities are encouraged to coordinate their forest
resource lands designations with their county and
any adjacent jurisdictions. Counties and cities should
not review forest resource lands designations solely
on a parcel -by -parcel basis."
Edmonds has established environmental qualitygoals
in support of the legislation and in order to protect
critical areas. Since the critical areas regulations
must be consistent with the Comprehensive Plan,
the Comprehensive Plan sets forth the underlying
policies for the jurisdiction's critical areas program.

The Comprehensive Plan (2016)
As an overarching guiding document, the
Comprehensive Plan aggregates other city visions
and plans into one cohesive document. The
Comprehensive Plan is structured by element, then
goals, then policies.
The Comprehensive Plan contains 9 elements. These
elements include goals and policies that can be
directly supported through this UFMP. These are the
community sustainability elements of the plan and
include goals and policies associated with:
• Sustainability
• Climate Change Goals and Policies, including
support for the Kyoto Protocol and the US
Mayor's Climate Change Agreement
• Community Health
• Environmental Quality
Theurbanforestisa keycomponentofthe community
sustainability element. Goal A in this element seeks
to protect environmental quality and sets the first
policy (A.1) as to: Ensure that the city's natural
vegetation, especially native vegetation, associated
with its urban forests, wetlands, and other wildlife
habitat areas are protected and enhanced..." A.2
sets to protect and retain the urban forest, native
vegetation, and wildlife habitat areas. This includes
techniques such as tree retention, which should be
integrated into land use and development codes. As
the urban forest grows, so too does the habitat and
environmental quality.
The community culture and urban design element's
implementation involves tree policy as well. In
this element, the streetscape section defines the
many ways that trees enhance the community:
"Trees are an asset to the community. They help
absorb stormwater, provide habitat for wildlife,
clean pollution from the air, and give both
summer shade and aesthetic pleasure." In this
way, the Comprehensive Plan addresses the policy
commitment to Community Health, through the
preservation and expansion of the urban forest.
Street trees are further explored in the Streetscape
Plan developed in 2002 by the Parks, Recreation, and
Cultural Services Department and updated in 2006.
The Streetscape Plan includes a Street Tree Plan for
the downtown corridor. In 2011 the City adopted a
"Complete Streets" program which accommodates
the needs of all users along streets, including a safe
space for pedestrians which necessitates a tree
management component. This section concludes
with Actions A.1 and A.2, which state that Edmonds
should update the Street Tree Plan and develop an
Urban Forest Management Plan by the end of 2017.
The community sustainability element also includes
two other sections that are interconnected with the
urban forest; Climate Change and Critical Areas.
Recognizing the importance of addressing the issues
surrounding the environment and climate change,
the City of Edmonds formally expressed support
for the Kyoto Protocols, adopted the U.S. Mayors
Climate Protection Agreement by Resolution No.
1129, and joined the International Council for Local
Environmental Initiatives (ICLEI) by Resolution No.
1130. A crucial component of these climate change
policies is the reduction of greenhouse gases with
several benchmarks:
1. By 2020, reduce overall emissions of green-
house gases in the state to 1990 levels;
2. By 2035, reduce overall emissions of green-
house gases in the state to twenty-five
percent below 1990 levels;
3. By 2050, the state will do its part to reach
global climate stabilization levels by reduc-
ing overall emissions to fifty percent below
1990 levels, or seventy percent below the
state's expected emissions that year.
The Edmonds urban forest is vital to the success of
meeting these benchmarks. Trees reduce carbon
through many ways including; reducing energy
demand for shaded buildings, acquiring carbon
dioxide for the photosynthesis, and sequestering
carbon. The potential for carbon sequestration
is determined by maximum tree sizes, lifespans,
growth rates, and tolerances to urban stress.
Therefore, growing long-lasting and healthy trees
directly contributes to the success of Edmonds
Comprehensive Plan climate change goals.

The PROS Plan (2016)
The Parks, Recreation and Open Space (PROS)
Plan provides comprehensive guidance on the
management and development of Edmonds' parks,
recreation and open spaces, and the services
provided by the Parks, Recreation and Cultural
Services Department. The PROS plan has been
regularly updated (1996, 2001, 2008, and 2014) to
remain relevant to Edmonds as the city evolves.
Edmonds updates the PROS Plan and Community
Cultural Plan on a six -year cycle, in alignment with the
requirements of the Washington State Recreation
and Conservation Office (RCO) to maintain eligibility
for federal and state grant programs. To this end,
the PROS plan contains detailed data on numerous
species and habitats in the city. The PROS Plan is
also an important tool in meeting Washington's
Growth Management Act (GMA) requirements and
achieving the important citywide goals outlined in
the Strategic Action Plan (April 2015). The PROS Plan
defines seven goals, of which Goal 4.0 specifically
addresses urban forestry.
Goal 4.0 (Natural Resource and Habitat
Conservation) seeks to preserve and provide access
to natural resources for habitat conservation,
recreation, and environmental education. The
eight objectives discuss preserving and protecting
areas with critical habitats and natural resources.
Of special importance to the UFMP is Objective
4.5, which states "Expand the urban forest and
increase tree canopy in Edmonds". Under each
goal, the PROS Plan recommends projects and
initiatives. A recommended project (4.G) under Goal
4 is: "Steward the urban forest using appropriate
maintenance of street and park trees, clear removal
and replacement policies and providing information
about urban forestry to property owners." This
demonstrates the value of the urban forest to the
people of Edmonds as manifested through existing
official documents addressing the urban forest and
urban tree canopy.
Summary Considerations for
UFMP
These documents demonstrate the existing
regulations and policies within which care for the
urban forest is mandated. It is clear from the scope
defined within these documents that the values of
the Edmonds community, and Washington State at
large, require that urban forest management include
strategies to improve the care and conservation of
all trees. This includes consideration for improving
and preserving trees near waterways, critical areas,
habitats, and on private parcels. Equipped with
this policy background and mandate to manage
the urban forest, it's essential to plan with as much
knowledge about the community tree resource as
possible.

What Do We Have c v

Community Tree
Resource
Trees belonging to the public, in parks, along rights -
of -way and around City facilities are the community
tree resource. These trees can be the most actively
managed population by the City and provide the
best indicators to showcase its vision of a well -
managed and sustainable urban forest condition.
A well -managed urban forest is healthier and more
resilient to pests, disease, and climate fluctuations.
As a result, a well -managed urban forest is also more
cost-efficient. As urban forests evolve over time,
managers revise their strategies for individual tree
species based on past performance and emerging
prospects. Because trees are relatively long-lived
organisms, urban forests, like those in Edmonds,
are often a combination of well -adapted, high-
performance species mixed with some species that
may be less desirable and require more attention.
There is a widely accepted guiding rule in tree
resource management that no single species should
represent greater than 10% of the total population,
and no single genus more than 20% (Clark et al,
1997). Achieving a diverse population of trees
can help to minimize detrimental consequences
in the event of storms, drought, disease, pests, or
other stressors that can severely affect an urban
forest and the flow of benefits and costs over time.
Catastrophic pathogens, such as Dutch elm disease
(Ophiostoma ulmi), emerald ash borer (Agrilus
planipennis) are both examples of unexpected,
devastating, and costly pests and pathogens that
highlight the importance of diversity and the
balanced distribution of species and genera.
Current operations in the City that care for the
community trees do not keep suitable records of
their tree resource to summarize within this UFMP.
Public trees along major arterials or high -profile
areas of the City are well-known and routinely cared
for by City Staff, but as an overall management tool,
the City does not maintain data about these trees
as a collective inventory of their green infrastructure
assets. Managing for appropriate tree species can
help control maintenance costs, reduce damage to
infrastructure, and manage the need for pest and
disease control measures.

6.A.e
Tree Canopy Cover
The amount and distribution of leaf surface area is
the driving force behind the urban forest's ability
to produce benefits for the community (Clark et al,
1997). As canopy cover increases, so do the benefits.
Tree canopy is the layer of leaves, branches, and
stems of trees and other woody plants that cover
the ground when viewed from above.
Understanding the location and extent of tree
canopy is critical to developing and implementing
sound management strategies that will promote the
smart growth and sustainability of Edmonds' urban
forest and the invaluable benefits it provides.
In addition to understanding the tree canopy as
a whole, the quality of the urban tree canopy is
often categorized by the amount of fragmentation.
Often, the health and diversity of the overall canopy
will vastly improve when there is less fragmented
canopy, and there are more linkages between
multiple patches of forest. These categories of
canopy include:
• Core Canopy - Tree canopy that exists
within and relatively far from the forest/
non -forest boundary (i.e., forested areas
surrounded by more forested areas).
• Perforated Canopy - Tree canopy that
defines the boundary between core forests
and relatively small clearings (perforations)
within the forest landscape.
• Patch Canopy -Tree canopy of a small -
forested area that is surrounded by non -
forested land cover.
• Edge Canopy - Tree canopy that defines
the boundary between core forests, and
large core forests and large non -forested
land cover features, approximately 328
feet. When large enough, edge canopy may
appear to be unassociated with core forests.
The City of Edmonds completed a canopy assessment
in June 2017 using a heads -up digitizing approach
and high resolution (4.8 inch), leaf -on aerial
imagery captured on August 7th, 2015. The overall
assessment does not distinguish between publicly -
owned and privately -owned trees because trees
provide benefits to the community beyond property
lines. The results of the study provide a clear picture
of the extent and distribution of tree canopy within
Edmonds.
The data developed during the assessment becomes
an important part of the City's GIS database. It also
provides a foundation for developing community
goals and urban forest policies. With these data,
managers can determine:
• The location and extent of canopy overtime
(tracking changes)
• The location of available planting space
(potential planting area)
• The best strategies to increase canopy in
underserved areas
• The data, combined with existing and
emerging urban forestry research and
applications, can provide additional
guidance in two ways:
• Finding a balance between growth and
preservation
• Identifying and assessing urban forestry
opportunities.

Canopy Cover Summary
The City of Edmonds encompasses a total area of
9.5 square miles (6,095 acres) with 1,844 acres of
tree canopy (Figure 1). This total area includes 8.9
square miles of land and 0.6 square miles of water.
By analyzing high -resolution aerial imagery, Davey
Resource Group (DRG) determined the following
land cover characteristics within the City of Edmonds:
• 30.3% existing canopy, including trees and
woody shrubs (525 acres)
• 1.6% (99 acres) dry vegetation and bare
ground
• 6.6% (402 acres) open water, where tree
canopy is unfeasible
• 27.4% (1,670 acres) of grass and low-lying
vegetation
• 34.1% impervious surfaces, including roads,
parking lots, and structures (2,080 acres)
• From 2005 to 2015 tree canopy decreased
from 32.3% to 30.3%
• Total possible canopy is 57.4%, considering
suitable planting sites (1,651 acres) and the
existing canopy (1,844 acres), for a total of
3,495 acres
• Private properties have most of the canopy
(83.0%), followed by public (12.9%), and
commercial (4.1%) properties.
• Among parks in Edmonds, Snohomish

Canopy Fragmentation
As a part of the UTC assessment, Edmonds' existing
UTC was analyzed for fragmentation to discover the
distribution of canopy (Map 2). The overall health
of the urban ecosystem is highly dependent on the
ability of the trees, plants, wildlife, insects, and
humans to interact collectively as a whole.
Often, the health and diversity of the overall canopy
will vastly improve by creating linkages between
multiple patches of forest.
Canopy fragmentation data serves as a valuable
management tool due to the importance of Edmonds'
critical areas and environmental stewardship. The
analysis found that Edmonds' urban forest includes
the following:
• 10.3% (190 acres) of Core Canopy
8.2% (151 acres) of Perforated Canopy
55.5% (1,023 acres) of Patch Canopy
26.0% (480 acres) of Edge Canopy

Park Canopy Cover
The City of Edmonds includes 47 parks covering
344 acres (5.6% of all land area) (Map 3). Edmonds'
parks have an average tree canopy cover of 44.1%.
Within those parks, canopy varied depending on site
and size. Edmonds' largest park, Snohomish County
Park (119 acres), has 117 acres of tree canopy and
an average canopy cover of 98.7%. The second-
largest, Yost Memorial Park (44 acres) has 41 acres
of canopy cover, which represents 93.5% of the
land area. The high canopy cover of Yost Memorial
Park reflects that it is one of the few areas of native
vegetation that remain in Edmonds. The park
contains mixed stands of western red cedar (Thuja
plicata), red alder (Alnus rugosa), bigleaf maple
(Acer macrophyllum) and western hemlock (Tsuga
heterophylla), which offer a glimpse into the natural
history of the area. Centennial Plaza is the smallest
park (less than 0.1 acres) with 0.02 acres of canopy
(9.9 % canopy cover).
Of the four largest parks (Snohomish County, Yost
Memorial, Meadowdale Beach, and Pine Ridge), all
have high tree canopy potential (greaterthan 96.7%).
However, of these parks, only Pine Ridge Park is not
currently near maximum potential canopy.
An acceptable strategy is to focus attention on the
parks where there is a much larger gap between
current canopy cover and potential canopy cover. For
example, Mathay Ballinger Park has 54.4% canopy
cover, but the potential is 93.8%. Haines Wharf
is another example where the potential canopy
(40.6%) is much higher than the existing canopy
(11.9%). The 5 biggest parks are listed at right.

Critical Areas
The Washington State Growth Management Act
(GMA) mandates that all cities and counties in
Washington are required to adopt critical areas
regulations. The GMA states that critical areas
include the following categories and ecosystems:
• Wetlands
• Areas with a critical recharging effect on
aquifers used for potable water
• Fish and wildlife habitat conservation areas
• Frequently flooded areas; and
• Geologically hazardous areas
Analysis of critical areas in conjunction with tree
canopy can reveal the important relationship that
trees provide in the conservation and protection of
these environments. Two critical area designations
are especially importantto urban forest management
in Edmonds; fish and wildlife habitat areas and steep
slopes (Tables 8 & 9).
Fish and wildlife habitat areas include high priority
habitats and species that have been identified for
conservation and management.
DRG analyzed the relationship between forest
fragmentation and the following priority habitat and
species list categories:
• Biodiversity and Corridor Areas (Breeding
and Refuge)
• Nesting Habitat (great blue heron)
• Sensitive Aquatic Habitat (Trout/Salmon)
• Sensitive Habitat (bald eagle)
• Wetlands Area
Biodiversity areas and corridors, identified by
the Washington Department of Fish and Wildlife,
are areas of habitat that are relatively important
to various species of native fish and wildlife. In
Edmonds, most of the biodiversity areas and
corridors are in core (58.6%) or edge (21.4%) forest.
This is congruent with what theory would suggest,
because corridors are continuous areas of habitat.
Nesting habitatforthe great blue heron is comprised
of several elements; the nesting colony, year-round
and seasonal buffers, foraging habitat, and a pre -
nesting congregation area. For a given nesting area,
habitats are delineated by a buffer created from the
outermost perimeter of great blue heron nests.
In addition, there is a larger seasonal buffer to
reduce human noise pollution during the breeding
months (February - September). Nesting habitat in
Edmonds is located primarily in non -forest areas
(58%). This value warrants further investigation to
determine optimal canopy levels.
Sensitive aquatic habitat is determined by in -stream
physical characteristics (e.g., temperature, water
quantity, structure, substrate conditions, etc.).
However, sensitive aquatic habitat is also strongly
influenced by watershed processes beyond the
waterline. This includes canopy cover, riparian

condition, large woody debris, impervious surfaces
and stormwater discharge, sediment delivery, road
location and maintenance, watershed hydrology,
and nutrient dynamics (Washington Department
of Fish and Wildlife, 2009). In Edmonds, 43.4% of
sensitive aquatic habitat is found in non -forest areas.
The second largest forest fragmentation category
for sensitive aquatic habitat is edge forest (29.9%).
Nesting habitat for bald eagles is typically defined
by areas of large, mature trees close to large bodies
of water and generally buffered from human activity
(Department of Fish and Wildlife, 2016). This nesting
behavior is reflected in the 11.9% of nesting area
located in edge type forests of Edmonds.
However, nest trees are often among the largest
trees in a forest patch (Department of Fish and
Wildlife, 2016). This tree preference is reflected in
18.6% of nesting habitat being found in patch forest.
Around wetlands, the Washington Department of
Ecology defines vegetated areas adjacent to aquatic
resources as buffers that can reduce impacts from
adjacent land uses (Washington Department of
Ecology, 2011). These buffers also provide some
of the terrestrial habitats necessary for wetland -
dependent species that require both aquatic and
terrestrial habitats. The quality of these buffers
could be described by their canopy fragmentation,
where 73.6% of wetlands were classified in non -
forest areas, and 16.8% were classified in edge
forest, with only 2.2% in the core forest.
The protection of steep slopes against landslides and
erosion is a key benefit of vegetation (Washington
Department of Ecology, 2011). Trees provide several
benefits to the structural integrity of slopes and the
prevention of soil erosion:
• Foliage intercepts rainfall, causing
absorptive and evaporative losses that
reduce rainfall available for infiltration.
Roots extract moisture from the soil which
is lost to the atmosphere via transpiration,
leading to a lower pore -water pressure.
Roots reinforce the soil, increasing soil shear
strength.
It is important to understand the significance of
steep slopes because of their influences on local
wildlife and habitat quality. For example, increased
erosion can negatively impact spawning salmon by
increasing sediment and particulates in streams and
other water bodies. In this way, riparian vegetation
that prevents erosion protects critical habitat for
wildlife.
Most steep slopes (66.1%) are in areas with tree
canopy. This figure presents an excellent baseline, as
trees are a vital tool for securing soil and minimizing
erosion. Among all areas with slopes over 12 degrees,
66.1% of the area is canopy, 14.3% is impervious,
19.0% is pervious, and 0.6% is bare soil.

Edmond's land cover data was used within i-Tree
Canopy to model the environmental benefits from
the entire urban forest (all public and private trees).
The trees in Edmond's are providing air quality
and stormwater benefits worth nearly $1.6 million
annually. To date, trees in Edmonds are storing
187,590 tons of carbon in their leaves and woody
biomass. The stored carbon is valued at $6.8 million.
Annually, tree canopy in Edmonds provides the
following environmental services:
• Reduces 42.8 million gallons of stormwater
runoff, a benefit worth nearly $1.2 million.
• Improves air quality by removing 42.2 tons
of pollutants (CO, NO2' 03, SOz) and PM10)1
valued at $146,823.

Summary Considerations for
UFMP
The UTC assessment establishes a GIS data layer
that can be used in conjunction with other map lay-
ers to prioritize planting sites and increase canopy
cover strategically. Edmonds' existing tree canopy
covers 30.3% of the City, and decision -makers can
set a target canopy cover goal to pursue. With this
UTC assessment, urban forest managers have the
following opportunities:
• Use priority planting site analysis to identify
new tree planting locations to reduce
erosion and soil degradation.
• Use GIS canopy and land cover mapping to
explore under -treed neighborhoods and
identify potential planting sites.
• Incentivize tree planting on private property,
particularly in high/very high planting
priority areas.
• Increase canopy with tree planting in areas
of patch and fragmented canopy to reduce
forest fragmentation and improve wildlife
habitat and corridors.
Conducting outreach to the community with
this report as an important tool for engaging
public interest and support.
• Define canopy goals and identify actions
that will support these goal(s).
• Develop clear policies and standards
to meet the 30% native vegetation
requirement codified by ECDC 23.90.040.0
(Retention of Vegetation on Subdividable,
Undeveloped Parcels) in undeveloped (or
redeveloped) Subdividable lands zoned
as RS-12 or RS-20, that contain a stream
or stream buffer, or a wetland or wetland
buffer.
Currently, forestry operations in the City do not
document the community tree resource according
to industry best management practices. A public
tree inventory is important because it provides
information on species diversity, forest age, and
relative performance of different tree species. An
inventory that is maintained with continued up-
dates also facilitates planning and prioritization of
tree maintenance duties. Based on this assessment,
urban forest managers have the following opportu-
nities:
Establish and continually update a public
tree inventory.
Integrate maintenance cycles with the
public tree inventory database.
Study genus/species compositions to
ensure best -management diversity

Existing Urban
Forest Practices
There are three departments within the City of
Edmonds that have influence over the management
of the urban forest; Development Services (DS),
Public Works and Utilities (PW), and Parks,
Recreation and Cultural Services (PRC). Although
they share and communicate any issues related to
tree care and urban forest management, decision -
making authority is determined based on the
location of the trees. There is no specific staff person
or leadership team with overarching responsibilities
for guiding the management of the entire urban
forest in Edmonds.
Tree Maintenance
Tree maintenance is important at all stages of tree
life, but is especially critical for young trees as they
benefit from early structural pruning and training.

Tree Planting
Minor corrections, such as removing double leaders
or crowded branches, can be conducted at ground
level with minimal cost when a tree is young.
However, if left unattended, defects can evolve into
very expensive structural issues and increase the
risk of failure as trees mature, at which point it may
be impossible to correct the issue without causing
greater harm.
Over -mature trees require more frequent inspection
and removal of dead or dying limbs to reduce the
risk of unexpected failure. By establishing a budget
for maintenance, urban forest managers can plan
the necessary tree care at the appropriate life stage
when it is most beneficial and cost-effective.
At the City, tree maintenance is addressed most
frequently with reactive tactics. As issues related
to trees are identified by City Staff, work is
prioritized based on existing and available budgets.
Planning associated with tree management on
public properties is minimal with priority attention
given to ensuring the successful establishment of
new tree plantings and responding to hazardous
tree conditions. Currently, the Parks Department
performs certain routine tree inspections and
provides limited proactive maintenance activities
(typically associated with the care of trees after
planting to encourage successful establishment).
Within City rights -of -way, tree issues are uncovered
as part of routine safety inspections of sidewalks
and streets, where trees are only identified when
infrastructure is damaged by roots, or when tree
hazards are observed by public works staff. Similarly,
in City parks, trees will be prioritized for maintenance
when safety concerns are observed through routine
park maintenance activities.

Tree Maintenance Budgets
The majority of tree maintenance costs are
accounted for as general line items through the
parks department budget. As part of the annual
Tree City USA application, departments will
summarize their expenses. In 2017, the Edmonds'
urban forestry expenditures were $7.74 per capita,
which is more than the minimum $2 per capita for
Tree City USA designation and more than the $7.50
national average reported by the National Arbor Day
Foundation. Documented Edmonds' expenditures
have been in the range of $3 per capita in prior years.
Using the recent Urban Tree Canopy assessment
as a benchmark estimate, Edmonds' urban forest
produces about $1,567,000 in environmental
benefits and is maintained with a 2017 budget of
approximately $319,542.
Service Levels
To assess current urban forest workload and staffing
levels, an estimated 11 city staff members were
identified as persons who work with tree issues on
at least an intermittent basis every week. From those
who are involved with forestry issues or operations
on a more regular time basis, 3 individuals were
identified with a quantifiable amount of time each
week working with trees or tree -related issues.

Overall, there is evidence of good interdepartmental
cooperation. These general conclusions about the
shared responsibilities among staff resources at
the City are very important when the City evaluates
future staffing needs for urban forestry. Currently,
no one single position is designated as a Full -Time
Employee (FTE) dedicated to urban forestry.

Staff Training
The science of arboriculture, and the management
of urban forests are domains that are increasingly
recognized as special areas of expertise. Credentials
are increasingly requested by many municipalities
as evidence of competency. Bachelor's degrees in
Forestry, Urban Forestry, Environmental Sciences,
and Horticulture are often the base requirements
for leadership roles in urban forest management.
Professional credentials can also demonstrate
competency, with the most widely accepted
credentials in Washington State coming from the
International Society of Arboriculture (ISA).
The City provides on -going training to any staff
handling tree maintenance equipment, including
chainsaw, chipper, and lift -truck safety. Stakeholder
interviews revealed that landscape maintenance
workers in Edmonds receive no formal training on
structural pruning or tree care. The following is a
summary description of staff resources and training
within individual City departments:
• In Development Services, staff are trained
to interpret ordinances related to trees, but
rely on reports by ISA certified arborists
when necessary to render decisions.
Staff within development services have
backgrounds in Urban Planning and one
(1) person with has an advanced degree in
Forestry. There are no ISA certified arborists
within development services staff.
• The Department of Public Works and
Utilities has a director with advanced
degrees in Biology and Aquatic Biology. In
addition, the department has engineers
on staff who can successfully consider
relevant tree issues in terms of asset and
infrastructure management, but tree care
expertise is not required for any staff in
this department. Tree- related issues are
resolved based on previous experiences
and through hired consultations with ISA
certified arborists when necessary.
• The Parks, Recreation and Cultural Services
Department has two staff members who
provide expertise on urban forestry topics.
The first is an ISA certified arborist who
is referenced by all City departments and
citizen groups for opinions on the best
practices associated with tree care. There is
also a staff member who has an advanced
degree in Forest Ecology who works
with citizen groups on tree planting and
stewardship projects.

Major and Emerging Diseases
and Pests
Another important aspect to tree maintenance is
staying alert to managing emerging diseases and
pests that can be costly to control with individual
trees. For sustainability of the entire urban forest,
these are potentiallycatastrophic matters to consider.
Further information on the pests and diseases that
threaten the forest ecosystems in Washington can be
found on the USDA's Forest Service website (https://
www.fs.usda.gov/detail/r6/forest-grasslandheaIth/
insects-diseases/?cid=stelprdb5287906).
Among the many diseases and pests that affect
trees, City Staff and residents remain alert to the
following:
• Asian Long -Horned Beetle (ALB), is an
invasive insect that feeds on a wide variety
of trees in the United States, eventually
killing them. The beetle is native to China
and the Korean Peninsula. Signs of ALB start
to show about three to four (3 — 4) years
after infestation, with tree death occurring
in ten to fifteen (10 - 15) years depending
on the tree's overall health and site
conditions. Infested trees do not recover,
nor do they regenerate. There are a broad
number of tree species this insect will feed
in and most common deciduous trees in
Edmonds are at risk.
• Emerald Ash Borer (EAB) has killed
Asian Long -Horned Beetle
py
� 1
hundreds of millions of ash trees in North
America. The EAB is a destructive, non-
native, wood -boring pest that exclusively
kills both stressed and healthy ash trees
two to three (2 — 3) years after infestation
(NASPF, 2005). EAB is a jewel beetle native
to Northeastern Asia. EAB larvae feed on
the vascular tissue of trees and populations
grow exponentially. This pest has been
identified as moving slowly into the Western
U.S. and is considered a catastrophic pest
for Ash tree populations.
• Dutch Elm Disease (DED) has devastated
American elm populations, one of the most
important street trees in the twentieth
century. Since first reported in the 1930s,
it has killed over 50 percent of the native
elm population in the United States (NASPF,
2005), although some elm species have
shown varying degrees of resistance.
• Swiss Needle Cast (SNC) is the name of
the foliage disease of Douglas -fir caused
by the fungal pathogen Phaeocryptopus
gaeumannii. SNC is known as a "cast"
disease because it causes the premature
shedding of needles (or casting) from
the tree. resulting in sparse tree crowns
and reduced growth. Although it is called
"Swiss" needle cast, the fungus is native to
the Western United States throughout the
range of Douglas -fir. SNC disease symptoms

include chlorotic (yellow) needles and
decreased needle retention, resulting in
sparse crowns and reduced diameter and
height growth (OSU, 2017). Mortality from
this disease is considered rare, but tree
care and maintenance of this disease can
be expensive and necessary in an urban
setting.
• Douglas -fir Tussock Moth (DFTM) is a
moth found in Western North America.
Its population periodically erupts in
cyclical outbreaks (Wickman et al., 1998).
Outbreaks of the Douglas -fir tussock moth
appear to develop almost explosively,
and then usually subside abruptly after a
year or two. The caterpillars feed on the
needles of Douglas fir, true fir, and spruce in
summer. Forestry management to prevent
tree damage from tussock moth outbreaks
include four activities: early detection,
evaluation, suppression, and prevention.
These four activities must be well integrated
to ensure adequate protection from the
pest.
• Other Diseases and Pests. Information on
specific diseases and insects that damage
trees in our region have been identified
by the Washington State Department
of Natural Resources. Current online
information is at: www.dnr.wa.gov/
ForestHealth.

Tree Acquisition and Quality
Control
Discussions with City Staff involved in acquiring and
planting trees did not reveal any standard practices
to ensure the quality of the trees during acquisition.
As trees are planted, there is no planned follow-up
or warranties managed with new trees
Tree City USA
The Arbor Day Foundation is a 501c3 nonprofit
conservation and education organization founded in
1972 in Nebraska, United States, by John Rosenow.
It is the largest nonprofit membership organization
dedicated to tree planting. The Foundation offers
Tree City USA certification. Cities can earn Tree City
USA certification by meeting four (4) core standards
of quality urban forestry management: maintaining
a tree board or department, having a community
tree ordinance, spending at least $2 per capita on
urban forestry, and celebrating Arbor Day.
Currently,the Cityof Edmonds dedicates$319,542.20
towards total community forestry expenditure, and
with a population of roughly 41,260, has a per capita
investment of $7.74. The Arbor Day Foundation has
recognized this per capita investment, as well as
recognizing the City of Edmonds' community tree
ordinance and observance of Arbor Day.

components relevant to urban forestry in the
Edmonds City Code and Community Development
Code. These regulations are designed to:
• Authorize the power of government to
manage the urban forest
• Define street trees and, as appropriate,
municipal responsibilities for their care
• Enumerate tree related fees and penalties
• Create regulations associated with tree
clearing on private land
• Require tree protection during construction
• Classify critical areas or buffers
These different regulations cover tree related
topics on a range of land types, and all influence
the direction and management of urban forestry
programs. The following summaries outline the
chapters and sections of city code.
Authorization of Power
The legitimacy of Edmonds' city government to
manage forestry domains and the definition of those
domains fall under the authorization of power:
• Chapter 18.45 provides for the City's
Planning Division Manager to direct and
enforce City codes related to land clearing
and tree cutting on public land and private
property. It exempts Public Works, Parks
and Fire Departments in specific situations
where safety is an issue.
• Chapter 18.85.030 provides for the Director
of Public Works to enforce and inspect work
done to maintain City street trees in healthy
condition, or remove trees from the public
right-of-way as necessary.
• Chapter 10.95.030 provides for a Tree
Bboard, made up of Edmonds City residents
in order to encourage civic engagement for
active stewardship of the urban forest. The
powers and duties of the Tree Board are to
advise and make recommendations to the
Mayor and City Council as appropriate on
tree related matters.
Street and Public Trees
The City of Edmonds is ultimately responsible for
the planting and maintenance of public trees.
These trees are on public property parcels or select
locations in the rights -of -way. Other planting strips
are the responsibility of adjacent land owners:
• Chapter 9.20.060, for sidewalk construction
and maintenance, declares that the
responsibility is with the abutting property
owner for maintaining or repairing adjacent
planting strips. This includes all tree care.
• Chapter 18.85 provides further clarity on
the regulation of street trees and trees
on public property. All street trees are
managed by the Public Works Department
and require permits for all persons who
wish to plant, remove, prune or otherwise
change a tree on a street, right-of-way,
parking strip, planting strip, or other public
place. This code chapter also includes
language defining abuse and damage to
street trees.
Tree Related Fees and Penalties
To facilitate compliance and remediation for
disregarding public tree codes, the City provides
penalties as a punitive deterrent:
• Chapter 18.45.070 defines the punitive
discretion for trees that are damaged from
disregard of City code of up to $1,000 for
trees less than 3" and $3,000 for trees
larger than 3". Fines can be tripled related
to trees in critical areas, buffers, or areas
dedicated to public use, including public
right-of-way.

6.A.e
Private Land Clearing
Land clearing on private property is often a critical
challenge to effectively reaching urban forestry
canopy goals. Individual private property rights and
objectives of private landowners can frequently
be at odds with the community aspirations for the
urban forest.
Chapter 18.45 contains regulations
associated with trees on private properties
for land clearing and tree cutting. This
code provides for a variety of purposes
that would preserve the physical and
aesthetic character of the City and prevent
indiscriminate removal or destruction of
trees. This chapter also implements policies
of the State Environmental Policy Act. It
provides special exemptions in 18.45.030
for improved single-family lots, partially
improved single-family lots or certain
unimproved lots, allowing private property
owners in these categories to maintain or
remove trees at their discretion without
permits. Additionally, these land clearing
codes provide exemptions for utility
vegetation maintenance or tree work by
City departments when situations involving
danger to life or property are found.
Tree Protection During
Construction
As new construction occurs throughout the Pacific
Northwest, many projects can damage or kill trees.
Regulations to protect trees during construction
are a mechanism to control canopy loss as sites are
developed.
Chapter 18.45 requires that trees that are
being retained during a land development
project are also protected. The codes
describe the protected area on a site
as being within the drip -line of the tree
and attempts to limit damage to trees by
controlling the impact to trees within this
area.
Critical Areas and Buffers
Washington State has special laws to protect critical
areas, which are defined for certain types of valuable
and environmentally significant areas.
• Chapter 23.40 establishes extra protections
and management requirements for trees
located near wetlands, streams, or steep
slopes. Tree pruning or removal is restricted
or prohibited without a report from an
ISA certified arborist, ASCA registered
consultant, or a registered landscape
architect that documents the hazard
and provides a replanting schedule for
replacement trees.

and Community Forestry (UCF) Program provides
technical, educational, and financial assistance
to Washington's cities and towns, counties,
tribal governments, nonprofit organizations, and
educational institutions. The mission of the UCF is:
"To provide leadership to create self-sustaining
urban and community forestry programs that
preserve, plant and manage forests and trees for
public benefits and quality of life."
A key service provided by the UCF is its collection of
financial assistance programs including; Community
Forestry Assistance Grants, Tree City USA Tree
Planting & Maintenance Grants, Arbor Day Tree
Reimbursements, Landscape Scale Restoration
Grants, Scholarships, and Internships. All forms of
financial assistance, their availability in a given year,
and their associated dollar amounts are dependent
on continued funding through annual grant
allocations from the USDA Forest Service. The UCF
communicates events, educational opportunities,
and other information through a Tree Link Newsletter.
The Washington Community Forestry Council
advises the DNR on policies and programs. The
program does this by teaching citizens and decision -
makers about the economic, environmental,
psychological, and aesthetic benefits of trees.
The program also helps local governments, citizen
groups, and volunteers plant and sustain healthy
trees throughout Washington. The council was
established under RCW 76.15.

Urban Forestry
Practices:
Case Studies
In order to remain progressive with its urban forestry
programs, the City of Edmonds recognizes that
there are urban forestry practices emerging from
other municipalities that could eventually add value
if developed within the City. Through stakeholder
interviews and discussions with City Staff, three
urban forestry practices were selected as important
for further consideration in implementation of this
UFMP: Tree Banks (orfee in -Lieu programs), Heritage
Tree Programs and Arborist Business Licensing. This
section explores some examples around how other
cities have adopted these programs.
Tree Banks - Fee -based
alternatives to tree replacement
Often in the course of urban forest management,
there can be logistical challenges associated with
replacing trees at the same site where trees are
removed. An increasingly common solution is
to provide developers and residents with the
opportunity to pay fees in -lieu of meeting their
landscaping requirements. Providing a fee or
financial guarantee option creates a system for
funding tree planting projects or even more
sophisticated landscape restoration projects that
improve the overall health and condition of the
urban forest.
Precedence for this option can be found at the
National level, with the U.S. Army Corp of Engineers.
In a Federal Rule published in April 2008, The U.S.
Army Corps of Engineers (the Corps) and the U.S.
Environmental Protection Agency (EPA) define an in -
lieu fee program as:
"A program involving the restoration,
establishment, enhancement, and/or
preservation of aquatic resources through
funds paid to a governmental or non-
profit natural resources management
entity to satisfy compensatory mitigation
requirements... Similar to a mitigation bank,
an in -lieu fee program sells compensatory
mitigation credits to permittees whose
obligation to provide compensatory
mitigation is then transferred to the in -lieu
program sponsor."
Snohomish County
Here, the government provides options for
permit applicants to engage the county, their own
contractor, or do the mitigation work themselves to
ensure that mitigation is achieved, even when it is
not possible at the proposed project site:
• 'Applicants may choose to perform the
off -site mitigation work on private property
either themselves or through their own
contractor, subject to all other provisions of
Section 30.62 SCC, or applicants may enter
into a voluntary mitigation agreement with
the County pursuant to RCW 82.02.020
under which the County will perform the
mitigation work on public property within
the same sub -drainage basin or watershed
resource inventory area (WRIA)." (POL-6210

MITIGATION FOR IMPACTS TO CRITICAL
AREAS ARISING OUT OF SINGLE-FAMILY
RESIDENTIAL CONSTRUCTION UNDER SCC

The following cities are examples of fee in -lieu
programs related to urban forestry. There is some
variation in how these fees are calculated, as well as
where the funds collected get administered.
City of Redmond
The City of Redmond calculates fee in -lieu to include
the cost of the trees. More importantly, the fee
also includes all costs associated with establishment
care. From Article IV Environmental Regulations:
• RMC 21.72.080 E.2. - Tree Replacement
Fee A fee in- lieu of tree replacement may
be allowed, subject to approval by the
Administrator after careful consideration
of all other options. A tree replacement fee
shall be required for each replacement tree
required but not planted on the application
site or an offsite location.

equipment), maintenance for two years,
and fund administration.
ii. The fee shall be paid to the City prior to the
issuance of a tree removal Permit.
iii. Fees collected under this subsection shall be
expended only for the planting of new trees
in City -owned parks, open spaces or rights -

City of Renton
The City of Renton has much more limited code
language. Fee in -lieu options are still at the City's
discretion, but only cover the cost of the tree and
installation. No funding for establishment care
is required in this code. However, the code does
directly designate the funds to be allocated to
the Urban Forestry Program fund, which provides
more discretion to the City with how the funds get
allocated:
• PAMC 11.13.050 B.3. Street tree
requirements in previously developed area.
In addition to the above requirements,
the following also apply: Where new
street trees cannot be planted due to
portions of rights -of -way having been
previously paved or otherwise rendered
unsuitable to plant trees, a fee -in -lieu
of planting is required. Such fee shall be
determined by the Community Forester
per City Policy and deposited into the
Community Forestry Fund. https://library.

recognized for their historical significance to the
community. This recognition is commonly referred
to as part of a Heritage Tree Program. These

City of Seattle
In the greater Puget Sound region, a number of cities
have heritage tree programs. One of the earliest
programs was for the City of Seattle in 1996 when
PlantAmnesty (a nonprofit) initiated a program
that eventually became co -sponsored by the City.
Seattle's program provides the broadest set of
categories for designating a tree as a heritage tree.
Trees can be designated according to the following
categories:
Specimen: A tree of exceptional size, form,
or rarity.
Historic: A tree recognized by virtue of its
age, its association with or contribution
to a historic structure or district, or its
association with a noted person or historic
event.
Landmark: Trees that are landmarks of a
community.
Collection: Trees in a notable grove, avenue,
or other planting.
City of Vancouver
The City of Vancouver, Washington, has had a
heritage tree program in place since 1998. Unlike
Seattle, which already regulates the care of
exceptional trees (including heritage trees) on
private property, the City of Vancouver uses this
designation to protect trees on private properties
where tree removal permits would not ordinarily
be required. This is a voluntary program for private
property owners, thus protecting the rights of the
property owner (https://www.cityofvancouver.us/
publicworks/page/heritage-trees).
City of Lynnwood
Closer to Edmonds, in the neighboring City of
Lynnwood, the Heritage Tree program is defined
in municipal code. Although many aspects of this
program are similarto other cities, their specific code
language binds all successive owners of the tree to
the protection obligations within this designation.
This language has the added benefit of ensuring
long-term protection and care for the tree unless it
is determined to be a hazard (LMC 17.5.070).
Arborist Business Licenses -
Ensuring Best Practices in Tree
Care
Businesses that operate in Edmonds only require
a general business license to work as an arborist.
This is not uncommon, but many cities are now
recognizing how the complexity of city codes
associated with tree care and the expectations
of the community necessitate special licensing
for businesses that perform tree work. Tree care
industry professionals and researchers in the
science of arboriculture routinely convene as the
International Society of Arboriculture (ISA), or the
Tree Care Industry Association (TCIA). These groups
collaborate to encourage best practices in tree care
and tree worker safety. To help ensure a community
has companies that are adequately trained and
qualified for tree work, the use of arborist licensing
that ties the business with these organizations is
increasingly popular. The following cities were
selected from throughout the U.S. as examples of
different approaches for arborist business licensing:
City of Herrington
• Herrington, KY — Businesses that practice
arboriculture must submit an application
to the City for a Tree Contractor license.
The application identifies the business
as practicing arboriculture and requires
proof of sufficient insurance (http://
www.cityofherington.com/pview.
aspx?id=32514&catl D=547).
City of Lincoln
• Lincoln, NE — In Lincoln, applications
for tree services and arborists not only
require proof of insurance, but also proof
of ISA credentials or a tree worker test
administered by the parks and recreation
department. http://Iincoln.ne.gov/city/
parks/communityforestry/arborist.htm
City of Denver
Denver, CO — Denver has two classes for
their "Tree Service License." This is a distinct
feature of their licensing process. Licenses

landscaping work on small trees that do
not require an aerial lift. https://www.

if they are doing work on public property
trees (e.g.,street trees and park trees).

Summary Considerations for
UFMP
Historical practices and regulatory requirements
provide a clear vision and mandate that direct the
City to manage the entire urban forest. In particular,
the City has special authority over property it owns
or that is within the public right-of-way. Yet, no
comprehensive public tree inventory exists. The City
also does not have a dedicated forestry specialist to
direct the City's urban forest management activities.
Instead, the City has multiple departments that
are guided by codes and policies for site -specific
decisions without overarching strategic level
guidance of the forest. An example encountered by
public works staff is when a tree removal is being
considered. One tree may need to be removed and
replaced for safety reasons, but additional trees may
get removed and replaced to maintain the aesthetic
of the streetscape. Without overarching urban forest
strategies, removals of trees for simple rights -of -
way improvements can be seen as reactive solutions
resolved through political discourse instead of
planned practical decisions for city managers.
This reactive approach to urban forest management
also extends to the tree care budget. The City does
not maintain sufficient tree related information
(such as tree quantity or condition data) to budget
for proactive tree care. Current urban forestry
benefits models show how trees in Edmonds
provide environmental and economic benefits that
are much greater than their reactive management
costs. There is tremendous opportunity to leverage
this disparity and direct forest management toward
proactive tactics such as tree planting, young tree
maintenance pruning, and tree inspections.
With the City having authority to care for
approximately 12% of the City's entire tree canopy,
other methods to encourage or require tree planting/
protection will be needed for the community to
have influence over tree care in the remaining
88% of the forest. Some strategies that have been
engaged in at other municipalities include the fee
in -lieu programs to support variances in any tree
replacement obligations, Heritage Tree Programs
that protect special trees, and arborist business
licensing to encourage best practices in tree care.
Finally, the City of Edmonds has both public and
nonprofit agencies committed to helping Edmonds
maintain a healthy urban forest. With continued
or greater engagement, the City may realize more
grant -funded opportunities, volunteer resources,
and engaged citizens who will help the City achieve
its urban forest management goals.

Stakeholder and Community Meetings
Community Input
Edmonds conducted substantial outreach to public
stakeholders, residents, and nonprofit agency
stakeholders. Connections and relationships that
develop among stakeholders are valuable outcomes
of the urban forest outreach process. This provided
a wide context for the challenges that face Edmonds'
urban forest. As community awareness and actions
associated with urban forestry move forward, it will
be the people of Edmonds that ultimately realize the
value of their contributions to their community in
the trees that grow around them.
Stakeholder Interviews
In the summer of 2017, a team from the Davey
Resource Group and Nature Insight Consulting
met with several municipal and regional urban
forest stakeholders. These stakeholder interviews
occurred over two days and included urban
planners, utility experts, public works staff, tree
board representatives, and City staff leadership.
Their valuable contributions guided the framework
of the UFMP.
Virtual Open House
Throughout the development process, the City
hosted a website that provided community access
to the planning process. In addition, the website
provided access to videos of public presentations,
surveys, and invitations for public comments. This
approach provided further opportunities for public
input outside of scheduled community meetings.
The first public meeting was held with the City of
Edmonds Citizens' Tree Board on May 4, 2017.
During this meeting, issues, concerns, and values
about the urban forest were explored with members
and visitors in attendance.
Later, on June 22, 2017, the City of Edmonds hosted
the first of two open houses (Appendix D) at City Hall
to share information about the UFMP development
process and gather input from community
residents. The open house included a presentation
and a brief discussion with the audience to answer
clarifying questions. Following the presentation,
attendees were invited to provide input (thoughts,
ideas, concerns, questions) on six opinion poster
boards. Each poster board contained a broad
topic followed by initial suggestions generated
through the prior stakeholder interview process.
Attendees were invited to express their opinions
using dots (where green = a positive "vote"/
agreement for the suggestion, yellow = concern/
hesitation of the suggestion, and red = a negative
"vote"/disagreement or dislike of the suggestion).
Attendees were invited to use as many dots of
each color as necessary to express their opinion of
each suggestion on each poster board. In addition,
each poster board provided an area for Additional
Suggestions, where attendees were invited to write
down their thoughts, ideas, concerns, and questions
on a sticky note. The sticky note was then adhered
to the poster board for other attendees to review
and "vote" on.
A third meeting which was with the Planning Board,
occurred on July 26, 2017 as another opportunity
to solicit public participation early in the UFMP
development process. The results of these public
meetings helped the City to understand the needs
and concerns of the community and guide the
development of the online survey.

Online Community Survey
From the initial stakeholder outreach, a survey was
developed with the intention of understanding and
benchmarking Edmonds' community values and
views on the urban forest. Survey data was collected
online. The survey platform only allowed one survey
response per household to control for multiple
entries from a single respondent. The survey closed
in September of 2017 with 175 responses having
been gathered through the summer (Appendix
C). Responses increased following the public open
house and a presentation to the planning board.
Although the intent was to gather feedback from a
broad representation of the community, 40.9%ofthe
respondents affiliated themselves with the Edmonds
Bowl area, with another 15.2% affiliating with the
Seaview neighborhood. Other neighborhoods had
less than fifteen (15) responses each, about 29.3%
of the combined total. 14.6% (24 responses) did not
affiliate within the survey -defined neighborhood
groups.
The results showed how seventy-five percent
(74.9%) of respondents "strongly agree" that public
trees are important to the quality of life in Edmonds.
Sixty-seven percent (66.9%) of respondents "agree"
or "strongly agree" that Edmonds needs more public

Summary Considerations for
UFMP
Already considered a valuable asset by Edmonds
residents, Edmonds has an opportunity to further
improve the urban forest through increased
public outreach and community engagement.
Public engagement on urban forestry issues has
demonstrated that the public is generally satisfied
with the City's activities on public property, but
prefers to have the City only provide guidance and
education as opposed to regulation when it comes
to stewardship of trees on private property.
There is general agreement from survey respondents
that trees impact views for many residents, and the
issue galvanizes residents as a primary tree issue
in Edmonds. In fact, views of the water and other
scenic places are fundamental to Edmonds' identity
as a community. Scenic views are also considered
a property right of long-established development.
At the same time, appreciation of trees —especially
"the right trees in the right place" —is a value shared
by almost everyone.

How Do We Get There?
Over the next twenty (20) years, the City of
Edmonds will be able to enhance management of
the urban forest through implementation of actions
recommended in this Plan. The decision to develop
a Plan with a 2038-time horizon was primarily based
on the precedence established by the City with
other long-range planning documents. Additionally,
growing and improving Edmonds' urban forest are
slow processes. Tree physiology for most trees in
Western Washington can take up to seven (7) years
to establish after planting, and anotherten (10) years
before they reach functional maturity. Trees provide
the majority of their ecosystem services when they
reach functional maturity. For this additional reason,
it is essential that urban forest planning consider at
least twenty (20) years within the Plan framework as
a reasonable expectation for achieving the desired
state of the urban forest.
The long-range strategic goals provided in this Plan
will address the three components of a sustainable
urban forestry program:
• Urban forest asset goals, which are
intended to improve the urban forest
resource over the next twenty (20) years
by developing detailed expectations for
the urban forest. To accomplish these
goals, the most common tactic will be to
increase the amount of information the City
maintains about its urban forest resource.
This includes activities like routine tree
canopy assessments and a public tree
inventory, both of which are fundamental to
management and are substantial expenses
to an urban forestry program requiring
significant consideration.
• Municipal resource goals, which are
intended to drive improvements in
City policy and practices by developing
efficiency and alignment of efforts within
City departments. The common tactics
for accomplishing these goals center
around developing policies that promote
routine tree inspection and formalized tree
management strategies for City -owned
trees. These goals encourage the City to
improve its awareness and mitigation of
tree hazards and eliminate barriers to
effective urban forest management.
• Community resource goals, which are
intended to build stronger community
engagement and public participation in
urban forest stewardship. The common
tactics for accomplishing these goals
coordinate with the public and encourage
the participation of citizens and businesses
to align with the City's vision for the urban
forest.
The research into current and historical efforts in
urban forestry at the City has revealed numerous
opportunities for Edmonds to enhance the
understanding of the urban forest resource as well as
improve efficiency in tree maintenance operations.
The criteria and indicators proposed by Kenney, et al.
(2011) were used as a standard to assess the current
urban forestry practices in the City, and provide
the management reference necessary to frame the
following recommended goals for this plan.

Urban Forest Asset Goals
Objectives
OF Goal #UA1- Maintain Citywide Canopy Coverage
Performance Measure -Tree Canopy Cover (% of City land covered by tree canopy)
Rationale - Edmonds has no set canopy goal. The current canopy 30.3% (1,844
Acres) is less than the 2005 Canopy cover (1,988 acres). This means that the City
has lost an estimated 6.2% (144 acres) since 2005.
Risk - Diminished canopy cover can increase flooding, urban heat island effects,
and energy use, reduce air quality, and degrade asphalt road surfaces. Canopy
loss also negatively impacts wildlife travel corridors and decreases habitat.
Benefit - Canopy cover can help optimize the ecosystem services provided by the
urban forest.
Actions:
A. Develop and adopt an overall canopy goal for Edmonds.
B. Adopt a City policy to avoid any net loss to the overall tree canopy.
C. Conduct urban tree canopy (UTC) analysis every ten (10) years to determine
changes and progress towards community canopy goals.

Rationale - Tree canopy in parks, steep slopes, and fragmented forest areas have
potential to reduce erosion risk and improve wildlife habitat.
Risk - Lack of tree canopy can result in erosion risk and reduced wildlife habitat.
Benefit - The City can develop efficient strategies for increasing canopy and
targeting specific areas to improve and distribute the benefits provided by the
urban forest.

Objectives
OF Goal #UA3 - Manage Tree Population Age Distribution for Diversity
Performance Measure - Distribution of trees per DBH Class (%) in city parks and
public Right -of -Way
Rationale - Maintenance costs and expensive end -of -life tree care are more
evenly distributed when a population has an ideal distribution of tree ages
(approximated by DBH).
Risk - City Staff suspect an uneven age distribution in many parks and natural
areas. There is concern about increased risks of whole tree failure due to a
growing number of trees in decline. Serious and substantial expenditures on tree
removals can be necessary in even -aged populations that reach the end of their
useful life in a few years.
Benefit- Annual costs for care of public trees can be more evenly distributed over
many years.
Actions:
A. For any tree inventory efforts, collect DBH to estimate tree age.
a. Create removal plans for the eventual decline (particularly for large
and risky trees).
B. Develop specific age distribution goals for different populations.

Performance Measure - % of City -managed property with Documented Tree
Inspection
Rationale - The City is not managing a database of trees. The City cannot quantify
tree assets, risks, or liabilities associated with its trees.
Risk - Without data on all publicly -owned trees, planning and prioritization of
urban forestry activities are based on conjecture and anecdotal evidence.
Benefit - The City can plan proactive tree management strategies and distribute
workloads efficiently.
Actions:
A. Develop a tree inventory policy for public trees.
B. Develop a standard tree inspection protocol.
a. Identify and prioritize plant health care needs/requirements.

Rationale - Aligning with the City's Comprehensive Plan elements, the City would
be favorably positioned to understand and optimize the ecosystem benefits
provided from trees by documenting and tracking the ecological function of
publicly -owned trees.
Risk- If services are not tracked, the value ofthe asset is unknown and preservation
and maintenance are more difficult to rationalize.
Benefit - Urban forestry projects will be easier to identify, finance, and secure
when cost -benefit relationships can be established and the information is shared
with the public.
Actions:
A. Complete a resource analysis (using i-Tree or another model).
a. Use i-Tree to evaluate the current composition, benefits, and benefit

Municipal Goal #M4 - Plant Trees Annually
Performance Measure - Number of Trees Planted Per Year
Rationale - To combat normal tree mortality, the City must engage in annual tree
planting or risk a decline in the size of the urban forest. Without data to quantify
the tree mortality rate, the number of trees that should be planted annually
cannot be determined. However, the 2017 canopy assessment suggests there
are 383 acres considered to be very high priority tree planting opportunities.
Risk - The number of trees in the City will decline without active replanting.
Benefit - This will guide the value of the ecosystem services provided by the
urban forest and control costs by proactively directing the future state of the
urban forest.
Actions:
A. Develop a tree planting and replacement plan as a supplement to the UFMP.
a. Use GIS mapping data to identify and prioritize planting sites and to
ensure coordination with planned improvements and construction.
b. Classify and prioritize available planting sites based on:
i. Space and minimum planting setbacks.
ii. Soil characteristics.
iii. Irrigation infrastructure.
iv. Landscape objectives and tree density.
v. Site constraints and existing infrastructure, including hardscape,
utilities (overhead and underground), bridges, and culverts.
vi. Invasive vegetation lack of native plants.
c. Place an emphasis on Right Tree Right Place.
i. Reducing hardscape and utility conflicts.
ii. Matching tree species to soil and water conditions.
iii. Matching tree species to planter size and intended use.
d. Optimize shade and environmental benefits by planting large stature
trees where feasible.
B. Set a replacement ratio of planting three trees for every one tree that is
removed in natural areas (3:1 ratio).
C. Ensure funding for trees and planting sites are included in projects funded
by Capital Improvement Funds (CIP).
a. CIP-funded projects should include adequate consideration of
trees and planter space, including the construction of planters and
pavements that support mature tree development and tree health
(e.g., suspended pavement, structural soils).

Municipal Goal #M5 - Update Street Tree Plan
Performance Measure -Updated City Policies on Street Tree Care
Rationale - Planting and tree care policies established within the Street Tree Plan
has been minimally updated since its original adoption. The City's Comprehensive
Plan also notes that the Street Tree Plan should be reviewed and updated
routinely. The plan should at a minimum comply with standards developed by
the American National Standards Institute (ANSI). The ANSI A300 Series applies
to tree care operations and ANSI Z133 safety requirements apply to employers
and employees engaged in arboricultural operations.
Risk - Without an updated Street Tree Plan, it is difficult for the public and
city staff to know the range of appropriate choices for street trees and related
information. Tree care practices and tree species selection could interfere with
elements of the UFMP strategic goals.
Benefit - An updated Street Tree Plan would identify a better range of choices for
street tree species. This will also help optimize daily operations and tactics with
alignment of long-term urban forest management strategies.
Actions:
A. A team composed of relevant City departments (especially, the Parks and
Recreation Department and the Public Works Department) would review
the current Street Plan, including previous draft revisions. The team will:
a. Identify key concerns and potential updates for the Street Tree Plan.
b. Get public input on proposed changes and take the revised Plan
through the appropriate adoption process.
B. Adopt as policy, the most current industry standards for all contractors and
in-house crews engaged in tree care operations.
a. City of Edmonds Tree Pruning Standards should adhere to current
industry standards and best management practices (BMPs).
b. Designate a City Staff member responsible for maintaining and
updating standards in accordance with industry standards and BMPs.
C. Ensure all public trees are on a regular pruning and maintenance cycle.
a. Incorporate trees at City facilities and parking lots into regular
maintenance and pruning cycles.
b. Incorporate significant trees and trees close to trails and accessible
open space areas into regular maintenance and pruning cycles.

Municipal Goal #M6 - Create a Dedicated Urban Forester/Arborist Staff
Position.
Performance Measure — As part of the City budget process, consideration of
adding a certified arborist to city staff resources.
Rationale —The City has a certified arborist as part of its Parks and Recreation
Department. The arborist helps advise on tree issues for City properties and
rights -of- way. This is effective for current needs of the Parks Department. The
City does not have a certified arborist as part of the Public Works Department
or Development Services Department. Adding a city arborist to either the
Development Services Department or Public Works Department would require
additional cityfunding. Currently, the Development Services Department requires
outside arborist assessments (paid for by the property owner) for various types
of tree removal and pruning.
Risk — Insufficient staff resources could limit active management of the urban
forest. Without a certified arborist in the Development Services Department, the
City would continue relying on outside expertise from certified arborists for issues
of tree removal and pruning on private property. Without a certified arborist in
the Public Works Department, public right-of-way work may be delayed.
Benefit — Having a certified arborist in the Development Services Department
would allow the Department to more quickly make decisions on tree removal
and pruning issues. This would add to General Fund costs but would save private
property owners time and/or money compared to obtaining outside professional
expertise for every required tree management decision. It would also result in
more consistency for such decisions.
If a certified arborist were added to the Public Works Department, that person
would be able to assist with tree maintenance issues without waiting for Parks
Department staff to be available or contracting with a non -City arborist to do the
work.
Actions:
A. Identify tasks and responsibilities for this position through an analysis of
the level of need for a certified arborist (for example, whether half-time,
full-time, or on contract) to assist the Development Services Department
and/or Public Works Department.
B. Further evaluate risks and benefits using contracted staff resources
C. The City Council will consider the level of need and the availability of funds
and, as part of a budget process, make a decision about adding an arborist

MF Goal #M8 - Update Development Regulations to Ensure Appropriate
Language for Protecting Trees and/or the Tree Canopy as Part of the
Development Process
Performance Measure — Ordinance Proposed to Update Tree -related Regulations
Rationale — The City's development regulations address tree protection
requirements in several places but staff and community have questioned whether
the language is consistent, clear, and adequate related to the development
process. Updating these requirements has been planned as part of a larger
code update but has not moved forward as rapidly as intended. Some updates
related to the urban forest could go forward sooner than the rest of the code
update. This would allow for the tree -related code language to be reviewed and
updated as appropriate to ensure that the city's tree canopy is maintained and
not compromised due to development.
Risk — If the regulatory language is not updated, tree protection requirements
for development may not be clear or adequate and the tree canopy could be
unnecessarily reduced.
Benefit — Development and change are part of urban life. At the same time,
management of the urban forest is important for overall quality of life. Code
language that is as clear as possible, especially related to trees and development,
will help ensure the best balance for the future. If a certified arborist were added
to the public works department, that person would be able to assist with tree
maintenance issues without waiting for Parks Department staff to be available or
contracting with a non -city arborist to do the work.
Actions:
A. Building on the City's past experience with tree codes, on examples from
other places, and on any other new information, the Development Services
Department should review the Edmonds Community Development Code
related to tree management and the development process.
B. The Development Services Department should confer with the Tree Board

among neighboring communities and regional groups.
Risk - Failure to integrate UFMP goals with regional goals may limit effectiveness
of Plan or risk conflicts with regional planning efforts.
Benefit - Regional partnerships can create pathways to stable and predictable
funding.
Actions:
A. Update existing planning documents to reference or validate the UFMP.
B. Identify organizations with urban forestry leadership roles at the regional
level.
a. Prioritize and formalize relationships
C. Maintain Tree City USA status.
D. Qualify and apply for Society of Municipal Arborists (SMA) Accreditation,
which requires:
a. At least one ISA Certified Arborist on staff.
i. ISA Certified Municipal Specialist preferred.
b. An Urban Forest Management Plan.
c. Tree City USA status.
d. A Tree City USA Growth Award within the past five (5) years.
e. Demonstrated preference to TCIA Accredited tree care companies
when private arborists are contracted.
f. Adherence to ANSI Z133.1 safety standards, and ANSI A300 tree care
performance standards.
g. A pledge of adherence to the SMA Code of Ethics and to promote SMA
objectives.

How Are We Doing?
Monitoring and
Measuring Results
The UFMP includes goals and actions for measuring
the success of planning strategies. It is intended
that the Plan serves as a living document. As new
information becomes available, this section of the
UFMP will be reviewed and amended using routine
plan updates, annual reports, and community
satisfaction surveys.
5-10 Year Plan Update (Plan
2023)
The UFMP is an active tool that will guide
management and planning decisions over the next
twenty ( 20) years. The goals and actions will be
reviewed every five to ten (5 -10) years for progress
and integration into an internal work plan. The
UFMP presents a long-range vision and target dates
are intended to be flexible in response to emerging
opportunities, available resources, and changes
in community expectations. Therefore, each year,
specific areas of focus should be identified. This can
inform budget and time requirements for Urban
Forest Managers.
Annual State of the Urban Forest
Report
This report, delivered annually, should include
numbers of trees planted and removed by the City,
and any changes to the overall community urban
forest (e.g., structure, benefits, and value). It will
serve as a performance report to stakeholders and
an opportunity for engagement.
The report is also an opportunity to highlight the
successful attainment of UFMP actions as well as to
inform stakeholders about any issues or stumbling
blocks. This information can be integrated into
urban forest managers' Annual Reports and used to
pursue additional project support and funding from
state agencies and Tree City USA applications.
Community Satisfaction
The results of the UFMP will be measurable in
improvements to efficiency and reductions in costs
for maintenance activities. Attainment of the goals
and actions will support better tree health, greater
longevity, and a reduction of tree failures. However,
perhaps the greatest measurement of success for
the UFMP will be its ability to meet community
expectations for the care and preservation of the
urban forest resource.
Community satisfaction can be measured through
surveys as well as by monitoring public support
for realizing the goals and actions of the Plan.
Community satisfaction can also be gauged by
the level of engagement and support for urban
forest programs. An annual survey of urban forest
stakeholders will help managers ensure activities
continue to be aligned with the community's vision
for the urban forest.

Community Survey Responses
Introduction:
The survey questions provided a public feedback
opportunity during the early stages of plan
development. They were designed to solicit
input from residents and businesses in the City of
Edmonds and help guide the plan development
by understanding about how respondents.
The questions were arranged into 4 groups:
• How do you value trees?
• Your opinion about public trees. (City
managed trees on streets and in parks)
• Your opinion about private trees.
(privately managed trees)
• Who are you? (Simple Demographics)
Question 2: Trees are known to provide benefits to the environment. Understanding which benefits
are most appreciated by residents can help guide long-term management strategies. Please rank (1-5)
the following ENVIRONMENTAL benefits in order of their value to you. (i.e., 1 = most valuable and 5 =
least valuable):

Appendix D: Open House
Summary Report
On June 22nd, 2017, the City of Edmonds hosted the
first of two open houses in the Brackett Room at City
Hall to share information about the City of Edmonds
Urban Forestry Management Plan and gather input
from citizens.
The open house included a presentation by Ian
Scott of Davey Resource Group and a brief Q and
A from the audience to ask clarifying questions.
The presentation provided attendees an overview
of Edmonds' urban forest, an introduction to what
will be included in the Urban Forest Management
Plan, and that the Davey Resource Group team has
completed to date. Following the presentation,
attendees were invited to provide input- thoughts,
ideas, concerns, questions- on six discussion/opinion
boards where a broad topic was introduced on each
board followed by initial suggestions generated
through the prior stakeholder interview process.
Attendees were invited to express their opinions
using dots (where green= a positive "vote"/
agreement for the suggestion, yellow= concern/
hesitation of the suggestion, and red= a negative
"vote"/disagreement or dislike of the suggestion).
Attendees were invited to use as many dots of
each color necessary to express their opinion of
each suggestion on each board. In addition, each
board provided an area for Additional Suggestions
where attendees were invited to write down their
thoughts, ideas, concerns, questions on a sticky note
and adhere it to the board for other attendees to
review and "vote" on, as well. Lastly, a confidential
and anonymous option was provided for attendees
to provide comments and feedback by writing their
thoughts, ideas, concerns and questions on index
cards that were placed inside a box and not shared
at the public meeting.
The Davey Resource Group team also provided a link
for attendees to give additional feedback through an
online survey. That survey can be accessed via the
home page on the City of Edmonds website, under
the "What's New..." section. The link provided is:
https://www.surveymonkey.com/r/EdmondsUFMP
Local media provided public announcements of the
open house leading up to the event:

This becomes a question of aesthetics- learn to see trees, which
are beautiful and characteristic of the luxuriant NW where we

have chosen to reside- as the "view". Trees are very connected
to the idea of "the commons" in which we have not much

Opinion Board #4: What level of
for oublic trees?
A. None (keep them natural)
B. Best possible care (all trees should look good)
C earance onl keep sidewalks and streets clear)
D. Take care of hazardous trees
E. Holistic plant health care (improve the urban forest, but
not necessarily every tree)
F. Additional Ideas
In past, City has been resistant to allow removal of dangerous
and dying trees even when 3 arborists said remove. Need
process to effectively deal with dangerous trees.
Utilize/ plant and replace trees that "heave" the sidewalks. ie-
avoid trees that interfere with built environment.
Native trees preferred. Alder are not trash trees
Edmonds is a City of Views- Very important that property
owner's views are protected. As a first step/tonight's meeting
working together to protect environment as well as property
owners will put this plan in a more optimistic mode.
There were not actually green dots placed on this Additional
Idea sticky note, but two other people wrote "Agree" directly on
the note itself.

Additional anonymous comments:
• Change name "Urban Forest"- bad
impression, oxymoron. Suggestion- Best
plant/tree for Best location
• Wondering what is/can be done to
encourage people to maintain views for
neighbors around them?
• Let's separate view areas from non -view
areas. Right tree for right location.
• I am concerned about safety regarding older
trees in both private and public spaces. We
have 70+ year old trees in our neighborhood
that lose branches with most wind storms.
Who watches out for the health of those
trees and probability of danger? Most
people would have no idea where to begin,
let alone be able to afford to do something
like hire an arborist. (signed J Thompson)
Questions from the public asked during the
presentation:
• Question regarding how the 30% canopy
cover was determined- comment that that
number seemed really high. Wondering if
there is a uniform process used by all cities.
Made comment that grants were judged
by how much canopy a City had. Asked for
clarification on what the process that was
used to determine 30% canopy cover.
• Question asking for clarification of the
intention of the UFMP- to handle City trees
(as stated in an early slide) or is it actually
expanded to handle private trees too.
• Commenter asked for clarification on
defining "what is a tree"- a 30ft lilac ... is that
a tree? A big rhododendron- is that a tree?
• Commenter referring to tree planting
suggestions (provided an sign in table on
yellow paper)- had a question about why is
there not any evergreen on that suggestion
guide?
• Commenter asked question regarding tree
topping being preferable to cutting a tree to
the ground. Expressed concern over making
a "blanket rule" that tree topping is bad or
not preferable.
• Question regarding information on what
kinds of trees do what kinds of things- eg. a
fir versus an oak- and where is that kind of
data available at?
• Question referring to the chart shown
in the presentation comparing Edmonds
with other cities- does that chart take
into consideration view property- does
it differentiate where there are view
properties and where there are not?
Commenter suggested that a significant
portion of the City [of Edmonds] has views.
