16.14.010 Findings.

The city council makes the following findings:

A. The trees of Lake Forest Park, a reminder of the city’s namesake, offer historic, aesthetic, ecological, economic, health, safety and welfare values to the community. Trees in the city of Lake Forest Park:

1. Improve the value of properties;

2. Reduce runoff via canopy interception, uptake of water from the soil and evapotranspiration back into the atmosphere;

3. Reduce runoff which results in less soil erosion and stormwater which aids in protecting surface waters from sedimentation and pollution;

4. Reduce the risk of flooding and infrastructure costs;

5. Improve air quality by removing dust and particulates from the air, and remove carbon dioxide while creating oxygen;

6. Provide cooling shade for homes, buildings, and asphalt/concrete surfaces, reducing heating and cooling costs for residences and other buildings;

7. Provide screening between different land uses or other objectionable views while buffering traffic and other noise;

8. Provide food and habitat for a variety of wildlife;

9. Provide visual relief from hard lines of concrete structures and other buildings;

10. Increase consumer patronage for commercial properties and boost occupancy rates for well-treed shopping areas;

11. Store carbon;

12. Contribute to human health improvement by lowering levels of fear of residents, and less violent and aggressive behavior by its citizens;

13. Encourage better neighbor relations and better coping skills for its residents; and

14. Provide a valuable asset to the community as a whole.

B. Removal of trees from urban areas such as Lake Forest Park has resulted in the loss to the public of these and many more beneficial functions of trees. (Ord. 1015 § 2, 2010)

16.14.020 Purpose and intent.

The purpose and intent of this chapter is to:

A. Implement certain strategies for the management and protection of Lake Forest Park’s urban forest resources described in those goals and policies of the Lake Forest Park community forest management plan that were accepted by the city council;

B. Preserve and enhance the tree canopy of Lake Forest Park by encouraging the protection of existing trees and stands of trees, and the replanting of new trees to replace those lost to old age, storms, development and other maladies;

C. Mitigate the economic, environmental, and aesthetic consequences of tree loss through protection and tree planting on public and private lands;

D. Provide guidelines to protect trees from adverse impacts during construction;

E. Encourage project designs that utilize existing trees in the landscape, or allow replacement of select native tree species to maintain the forested feel of Lake Forest Park;

F. To protect private property rights and allow property owners to make reasonable use of their property while protecting suitable and appropriate trees for that site; and

G. Maintain and protect the public health, safety, and general welfare. (Ord. 1015 § 2, 2010)

16.14.030 Definitions.

For the purposes of this chapter, the following terms are defined as follows:

“Administrator” means the planning director or the planning director’s designee.

“Best management practices (BMPs)” means adherence to tree health care standards detailed in

the current edition of the American National Standards Institute (ANSI) A300, the standards for proper tree care, including but not restricted to the following elements of tree protection and care:

1. Avoidance of physical damage to tree roots, stem, branches, and foliage;

2. Prevention of soil compaction from equipment operation and placement or storage of construction materials in the vicinity of the critical root zone (CRZ);

3. Protection of the critical root zone (CRZ) of saved trees from changes in drainage that impact soil moisture content;

4. Protection of existing trees from the impacts of exposure caused by removal of adjacent trees; and

5. Plant health care practices as published by the International Society of Arboriculture in their series of best management practices for the various aspects of tree care.

“Caliper” means the industry standard for measurement of nursery stock size. Caliper is measured six inches above the root collar for nursery stock four inches in diameter and smaller.

“Canopy” means the part of the tree crown composed of leaves and small twigs or the collective branches and foliage of a group of trees’ crowns.

“Canopy coverage” means a measure of the lot area that is covered by the canopies of existing trees and/or the canopy of the total of existing trees, immature trees, and newly planted trees. The canopy coverage of the immature trees and newly planted trees is determined using the projected canopy areas in the Lake Forest Park general tree list.

“Critical root zone (CRZ)” means the International Society of Arboriculture (ISA) definition of CRZ as an area equal to one-foot radius from the base of the tree’s trunk for each one inch of the tree’s diameter at 4.5 feet above grade (referred to as diameter at breast height). Example: A 24-inch diameter tree would have a critical root zone radius (CRZ) of 24 feet. The total protection zone, including trunk, would be 50 feet in diameter.

“Crown” means that portion of the trees stem that is occupied by branches with live foliage.

“DBH” is an acronym for tree diameter at breast height which means the diameter of existing trees measured 4.5 feet above the ground line on the high side of the tree. Multiple stemmed tree diameters shall be determined by equating the canopy coverage of the tree to that of a single-stemmed tree. For example, three 12-inch DBH stems on a multi-stemmed bigleaf maple tree may have the same canopy coverage as a single-stemmed 20-inch DBH bigleaf maple. Refer to the general tree list maintained by the city. For the purposes of code enforcement, if a tree has been removed and only the stump remains, the size of the tree shall be the diameter of the top of the stump adjusted to DBH using published tables or regression curves.

“Development activity” means any activity that requires federal, state, or local approval for the use or modification of land or its resource. These activities include, but are not limited to, variances; shoreline substantial development; clearing activity; excavation; embankment; fill and grade work; converting fallow land or undeveloped land to agricultural purposes; activity conditionally allowed; building or construction; revocable encroachment permits; and septic approval.

“Dripline” for a tree is delineated by a vertical line extended from the outermost branch tips to the ground, or six-foot radius from the stem of the tree, whichever is greater.

“General tree list” means a list of trees species that is maintained by the city and approved by the city’s qualified tree professional for planting as replacement and mitigation trees. The general tree list also establishes which tree species that are prohibited from being planted as replacement and mitigation trees. The general tree list may also contain additional information that is deemed by the city to be the basis for determining how many replacement trees may be required to meet the standards of this chapter.

“Hazard tree” means a tree that is dead, dying, diseased, damaged, structurally defective, or exposed by recent removal of adjacent trees which increases the risk of tree failure. The tree or tree parts have a target and the reasonable person would expect the tree to strike the target when failure occurs. A target is a person or property that may be injured or damaged by failure of the tree or its parts. Tree removal may be necessary if the tree cannot be made safe by pruning or moving of the target.

“Impact” means a condition or activity that affects a part of a tree including the trunk, branches, and roots within the dripline or critical root zone (CRZ).

“Landmark tree” means a tree that is at least 28 inches in diameter.

“Limits of disturbance” means the boundary between the area of minimum protection around a tree and the allowable site disturbance as determined by the city’s qualified tree professional.

“Live crown ratio” is the percentage of the total height of the tree that is occupied by the live green crown. For example, if the crown length, measured from the leader tip to the base of the live crown, is 55 feet and the total tree height is 100 feet, then the live crown ratio is 55 percent.

“Native” means trees and plants native to western Washington.

“New development” means construction associated with new subdivisions or short subdivisions as defined and applied in Chapter 58.17 RCW.

“Nuisance tree” means a tree that is causing obvious physical damage to structures, including but not limited to sidewalks, curbs, the surfaces of streets, parking lots, or driveways, or building foundations. The prescription to reduce the problem should include root or branch pruning, installation of root barriers, or other structures to eliminate or reduce potential for further damage. Tree removal should be considered as a last resort.

“Person” means an individual, corporation, municipal corporation, association, LLC (limited liability corporation), or any legal entity.

“Protected tree” means a tree and associated understory vegetation identified for retention and protection on an approved tree protection and replacement plan and/or permanently protected by easement, tract, or covenant restriction.

“Qualified tree professional” is an individual who is a certified professional with academic and field experience that makes them a recognized expert in urban forestry and tree protection during development. A qualified tree professional shall be a member of the International Society of Arboriculture (ISA) and/or the Association of Consulting Arborists and shall have specific experience with urban tree management in the state of Washington. Additionally the city’s qualified tree professional shall be a certified arborist or board certified master arborist, as certified by the International Society of Arboriculture, and have the necessary training and experience to use and apply the appraisal methodology prescribed in the current edition of the ISA Plant Appraisal Guide.

“Significant tree” means any healthy tree six inches or greater in diameter (DBH).

“Specimen tree” means a tree of exceptional size, form, or rarity.

“Street tree” means any planted tree on public rights-of-way.

“Tree” means a self-supporting woody plant characterized by one main trunk or, for certain species, multiple trunks, that is recognized as a tree in the nursery and arboricultural industries.

“Tree removal” means the direct or indirect removal of a tree(s) or vegetation through actions including, but not limited to: clearing, cutting, girdling, topping, or causing irreversible damage to roots or stems; destroying the structural integrity of trees through improper pruning; poisoning; filling, excavating, grading, or trenching within the dripline that results in the loss of more than 20 percent of the tree’s root system; or the removal through any of these processes of greater than 50 percent of the live crown of the significant tree.

“Understory vegetation” means small trees, shrubs, and groundcover plants, growing within the dripline or critical root zone (CRZ) of a significant tree.

“Viable tree” means a significant tree that a qualified tree professional has determined to be in good health with a low risk of failure, is relatively windfirm if isolated or exposed, and is a species that is suitable for its location.

“Wildlife snag” means the remaining trunk of a dead, dying, diseased, or hazard tree that is reduced in height and stripped of all live branches. To be considered as a wildlife snag, the tree must be at least 12 inches DBH and 20 feet tall. The actual snag height must consider the surrounding targets.

“Windfirm” means a tree that is healthy and well-rooted and the city’s qualified tree professional has evaluated and determined that it can withstand normal winter storms in Lake Forest Park. (Ord. 1015 § 2, 2010)

E. All removal tree permits issued as part of a subdivision or short subdivision shall have a condition on the face of the subdivision or short subdivision plat stating that minimum canopy must be achieved and maintained on each lot. For tree permits associated with any other new development proposals, including new residential or commercial development, variance requests, conditional use permits and reasonable use exceptions, a notice on title in the form required by LFPMC 16.16.190 shall be recorded by the permittee disclosing the tree permit and associated tree retention conditions required by this subsection. (Ord. 1015 § 2, 2010)

16.14.080 Tree retention and replacement standards.

This section provides standards for determining when and how trees must be retained or replaced. The city will apply these standards when considering an application for a tree permit under LFPMC 16.14.040.

A. The minimum standard for tree retention is determined by tree canopy coverage goal for the lot sizes and land use types set forth in Table 2 below. Tree canopy coverage is measured by the percentage of canopy provided by existing trees or the projected canopy coverage to be provided by newly planted or immature trees (when such trees reach 30 years of age).

Table 2


Canopy Coverage Goal

Single-family lots greater than 15,000 square feet


Single-family lots 10,000 – 15,000 square feet


Single-family lots less than 10,000 square feet






1. A person whose tree removal causes a lot’s canopy coverage to fall below the canopy coverage goal shown in Table 2 above shall obtain administrator approval of and implement a tree replacement plan that brings canopy coverage to the applicable percentage specified in Table 2 above (when the replacement trees reach 30 years of age).

2. Where the lot on which tree removal occurs is below the canopy coverage goal shown in Table 2 prior to tree removal, the person removing the tree shall obtain administrator approval of and implement a tree replacement plan that brings canopy coverage to the percentage that existed prior to the proposed tree removal (when the replacement trees reach 30 years of age).

3. A person obtaining an arborist review permit associated with new development shall obtain administrator approval of and implement a tree replacement plan that achieves the applicable minimum canopy coverage specified in Table 2 above (when the replacement trees reach 30 years of age).

B. New subdivisions, short plats, and new multifamily or commercial developments are required to create a tree tract equal to five percent of the gross project area. This tract shall be selected to save existing high quality, windfirm, long-term existing trees on the site. If suitable trees are not present, then the tree tract should abut other existing stands of off-site trees, or sensitive, or other undevelopable areas such as steep slopes. If all or portions of the tree tract are not treed, then the tract shall be replanted to achieve canopy coverage when the newly planted trees reach 15 years of age.

C. The priority for protection of healthy trees in developing, redeveloping, or existing lots that are being modified is:

1. Landmark trees;

2. Specimen trees or other high quality open-grown, windfirm trees;

3. Trees in critical area buffers, or adjacent to critical area buffers:

a. Trees that are interdependent with and therefore critical to the integrity of stands of other protected trees;

b.  Existing healthy trees in groups or stands;

c.  Other individual trees that will be windfirm, high quality trees if retained;

d.  Other trees that provide wildlife or riparian habitat, screening, buffering or other amenities;

e.  Trees that help to protect neighbors’ trees from windthrow, or other trees within required yard setbacks or on the perimeter;

f. Trees next to parks or other open space areas.

D. The administrator may require an applicant to implement other measures designed to mitigate the loss of trees, such as requiring the restoration of all or parts of the forest landscape and its associated benefits, including but not limited to:

1. Creation of wildlife snags from trees which would otherwise be removed;

2. Replacement of ornamental trees with native shrubs and groundcover;

3. Replacement of hazardous or short-lived trees with healthy new trees more likely to survive;

4. Restoration of stream corridors with native vegetation; or

5. Protection of nonsignificant trees to provide for the successional stages of forest development.

E. Measurement of Canopy Coverage.

1. Existing Open-Grown Trees.

a. Measure the radius of the tree’s canopy at its widest and narrowest points and calculate the average canopy radius for the tree.

b. Calculate the tree’s canopy coverage (ft2) using the average canopy radius and the formula: πr2 where π = 3.1416 and r = the canopy radius in feet.

c. Add up the calculated canopy coverage for all trees on the parcel in square feet and divide by the total lot area to determine the percentage canopy cover.

2. For contiguous stands of trees, traverse the perimeter of the stand within the parcel to calculate the area under the tree canopy and the resulting canopy percentage. In some cases, use of high-resolution aerial photography may be used for larger stands.

3. For newly planted or immature trees less than 30 years old, calculate the projected canopy coverage at age 30 using the information provided in the approved general tree list for the city of Lake Forest Park. Sum these canopy coverage areas to project the lot canopy coverage as trees reach an age of 30 years.

F. Incentives for Higher Levels of Tree Retention for New Development. The administrator may grant reductions or adjustments to other site development standards if doing so will allow retention of a sufficient number of existing, healthy significant trees and tree canopy coverage in excess of the goal required by Table 2 above. On a case-by-case review, the administrator shall determine the balance between tree protection that exceeds the established minimum percentage and variations to site development requirements. Authorized adjustments include:

1. Reductions or variations of the area or width of required open space, tree tract requirement, and/or landscaping;

2. Variations in parking lot design and/or access requirements; or

3. Reduction in the width of certain easements.

G. Tree Replacement Requirements. For lots under the canopy coverage goal that propose tree removal activity requiring an arborist review permit, native conifers shall comprise at least 30 percent of the replacement trees. The number of required replacement trees is determined by the number of trees that will, at age 30, achieve tree canopy coverage equal to or greater than the minimum canopy coverage required by Table 2 above for the type of lot. The replacement tree species shall be selected from the approved general tree list for the city of Lake Forest Park which is maintained by the city. Trees listed as prohibited in the general tree list are not acceptable for replacement or mitigation trees. Any substitutions of trees that are not on the list or alternative methods of replacement must be approved by the city’s qualified tree professional.

1. The minimum size of replacement trees should be:

a. Deciduous trees, two inches caliper.

b. Conifers, a minimum of six feet tall.

2. All trees must be containerized or balled and burlap stock and be planted according to industry standards.

3. All trees shall meet the minimum standards for size and quality according to the current edition of the ANSI Z60.1 standard for nursery stock.

4. A maintenance bond of 125 percent of the projected cost of tree replacement is required for required tree replacement on all new development projects. This bond will be maintained for 60 months after planting of the new trees.

5. The applicant is required to provide watering until replacement trees are independently viable. Replacement trees that die prior to meeting the definition of significant tree must be replaced by a replacement tree meeting the criteria of this section and any canopy coverage goal requirements that the expired tree was intended to provide.

H. On-Site Replacement. Replacement trees shall be planted on the site from which significant trees are removed. The administrator may waive the on-site tree replacement requirement; provided, that the applicant pays an amount determined by a qualified tree professional into the city tree account that is equivalent to the total cost for purchase and installation of each replacement tree and three years of maintenance for each replacement tree. (Ord. 1015 § 2, 2010)

16.14.090 Tree protection and design measures.

A. Tree Protection Measures. To ensure long-term viability of trees identified for protection:

1. All required tree protection measures shall be shown on the demolition, grading, and tree protection plan along with a timeline for tree protection activity.

2. All construction activities, including staging and traffic areas, shall be prohibited within five feet of the dripline of protected trees.

3. Tree protective fencing shall be installed at the limits of disturbance and completely around trees to be protected prior to any land disturbance unless otherwise delineated by the qualified tree professional.

4. Tree protective fencing shall be a minimum of four feet high, constructed of chain link or polyethylene laminar safety fencing or similar material, subject to approval by the city. The fence must be constructed on steel posts with a minimum spacing of eight feet on center. “Tree Protection Area – Keep Out” signs shall be posted visibly on all sides of the fenced areas.

5. Where tree protection areas are remote from areas of land disturbance, and where approved by the city, alternative forms of tree protection may be used in lieu of tree protective fencing; provided, that the critical root zones of protected trees or stands of trees are clearly delineated with continuous rope or flagging and accompanied by “Tree Protection Area – Keep Out” signs.

B. Tree Health. In addition, the applicant shall support tree protection efforts by employing, as appropriate, the following preventative measures, consistent with best management practices (BMPs) for maintaining the health of the tree:

1. Pruning of visible deadwood on trees to be protected;

2. Application of fertilizer to enhance the vigor of stressed trees;

3. Use of soil amendments and soil aeration in tree protection and/or replanting areas;

4. Mulching over tree dripline areas; and

5. Providing watering during and immediately after construction.

C. Alternative Methods. The city may approve the use of alternative tree protection techniques if a protected tree will be protected to an equal or greater degree than through the techniques listed above, as determined by the city’s qualified tree professional.

D. Grading and Proximity to Structures, Utilities, and Roadways.

1. Structures, utilities, and roadways shall be set back at least five feet from the dripline or critical root zone (CRZ), whichever is greater of a protected tree, except where such structure is a raised deck, bay window, or other structure cantilevered or otherwise raised above the ground’s surface so as not to disrupt the tree’s roots.
