W: Word Processing\Ordinances\Landscaping Code update -TMC 18.52 final 2-28-17
CL:bjs Page 4 of 23
2. Shrubs. Shrubs shall be spaced based on the mature size of the plant
material selected and shall achieve a continuous vertical layer within 3 years. The
shrubs will provide 4 feet clearance when mature when adjacent to any fire hydrant or
fire department connection.
3. Groundcover.
a. Sufficient live groundcovers of varying heights, colors and textures to
cover, within 3 years, 100% of the yard area not needed for trees and shrubs.
b. If grass is being used as the groundcover, a 4-foot diameter ring of
bark mulch is required around each tree.
4. Bioretention may be used as a Type I or 11 landscape perimeter, provided the
intent of the screen is achieved. To support bioretention facility function and plant survival,
flexibility in plant materials and placement shall be allowed, provided public safety is not
compromised.
5. The amount of landscaping on commercially-zoned properties may be
reduced by 15% if buildings are moved to the front of the site with no parking between the
building and the front landscaping, to create a more pedestrian-friendly site design.
B. Type I — Light Perimeter Screening.
1. The purpose of Type I landscaping is to enhance Tukwila's streetscapes,
provide a light visual separation between uses and zoning districts, screen parking
areas, and allow views to building entryways and signage.
2. Plant materials shall consist of the following:
a. Trees: A mix of deciduous and evergreen trees.
b. One shrub per 7 linear feet.
c. Groundcover.
C. Type 11 — Moderate Perimeter Screening.
1. The purpose of Type 11 landscaping is to enhance Tukwila's streetscapes,
provide a moderate visual separation between uses and zoning districts, screen blank
building walls and parking areas, and allow views to building entryways and signage.
2. Plant materials shall consist of the following:
a. Trees: A mix of deciduous and evergreen trees.
b. One shrub per 4 linear feet, excluding curb cuts.
c. Groundcover.
D. Type III — Heavy Perimeter Screening.
1. The purpose of Type III landscaping is to provide extensive visual
separation along property lines between highly incompatible development, such as
warehousing and residential uses.
W: Word Processing\Ordinances\Landscaping Code update-TIVIC 18.52 final 2-28-17
CL:bjs Page 5 of 23
2. Plant materials shall consist of the following:
a. Trees consisting of at least 50% evergreen along the applicable
property line (75% along property line adjacent to residential uses).
b. Privacy screen utilizing evergreen shrubs, screening walls or fences
(up to 7 feet tall).
c. Groundcover.
E. Parking Lot Landscaping. This landscaping is required to mitigate adverse
impacts created by parking lots such as noise, glare, stormwater run-off, and increased
heat and to improve their physical appearance.
1. Trees shall be evenly distributed throughout the parking lot. Planting in
continuous, landscaped planting strips between rows of parking is encouraged. Surface
water management design may also be combined with landscaping in parking lots. In
industrial districts (C/LI, LI, HI, MIC/L, MIC/H), clustering of interior parking lot
landscaping may be permitted to accommodate site usage.
2. Landscape islands.
a. Landscape islands must be a minimum of 6 feet wide, exclusive of
overhang, and a minimum of 100 square feet in area. All landscaped areas must be
protected from damage by vehicles through the use of curbs, tire stops, or other
protection techniques.
b. Landscape islands shall be placed at the ends of each row of parking
to protect parked vehicles from turning movements of other vehicles.
c. The number and stature of trees shall be based on the area available
in the landscape island. A minimum of one large stature evergreen or deciduous tree or
two medium stature trees are required for every 100 square feet of landscaped island,
with the remaining area to contain a combination of shrubs, living groundcover, and
mulch.
d. For parking lots adjacent to public or private streets, if landscape
islands are designed into the parking lot layout to divide continuous rows of parking
stalls, the islands must be placed at minimum spacing of 1 for every 10 parking spaces.
For parking areas located behind buildings or otherwise screened from public or private
streets or public spaces, if landscape islands are used, islands shall be placed at a
minimum of 1 for every 15 parking stalls.
3. Bioretention, which includes trees, shrubs and groundcover, may be used
to meet interior parking lot landscaping requirements. The bioretention facility must be
designed by a professional trained or certified in low impact development techniques as
set forth in TIVIC Chapter 14.30. All bioretention facilities must be protected by curbing
to prevent vehicle damage to the facility and for public safety.

(4) At least 7-1/2 feet from driveways.
(5) At least 3 feet from pad-mounted transformers (except 10 feet in
(6) At least 4 feet from fire hydrants and connections.
d. Planting and lighting plans shall be coordinated so that trees are not
planted in locations where they will obstruct existing or planned street or site lighting,
while maintaining appropriate spacing and allowing for their size and spread at maturity.
e. Planting plans shall consider the location of existing or planned
signage to avoid future conflicts with mature trees and landscaping.
2. Tree grates.
a. Tree grates are not encouraged, but when used, shall be designed so
that sections of grate can be removed incrementally as the tree matures and shall be
designed to avoid accumulation of trash.

Notes:
1. Minimum required front yard landscaped areas in the MDR and HDR zones
may have up to 20% of their required landscape area developed for pedestrian and
transit facilities subject to the approval criteria in TIVIC Section 18.52.100.6.
2. In order to provide flexibility of the site design while still providing the full
amount of landscaping required by code, the front yard landscape width may be divided
into a perimeter strip and one or more other landscape areas between the building and
the front property line if the perimeter strip is a minimum of 10 feet and the landscape
materials are sufficient to provide landscaping along the perimeter and screening of the
building mass.
3. Required landscaping may include a mix of plant materials, pedestrian
amenities and features, outdoor caf6-type seating and similar features, subject tothe
approval criteria in TIVIC Section 18.52.100.B. Bioretention may also be used as
required landscaping subject to the approval criteria in TIVIC Section 18,52.100.E.
Required plant materials will be reduced in proportion to the amount of perimeter area
devoted to pedestrian-oriented space.
4. Increased to 10 feet if any portion of the yard is within 50 feet of LDR, MDR
or HDR.
5. Increased to 15 feet if any portion of the yard is within 50 feet of LDR, MDR
6. Increased to Type 11 if the front yard contains truck loading bays, service
areas or outdoor storage.
7. Increased to Type 11 if any portion of the yard is within 50 feet of LDR, MDR
8. Increased to Type III if any portion of the yard is within 50 feet of LDR,
MDR or HDR.
9. Only required along public streets.
10. Increased to 10 feet if adjacent to residential uses or non-TSO zoning.
11. In the MDR and HDR districts and other districts where multifamily
development is permitted, a community garden may be substituted for some or all of the
landscaping. In order to qualify, a partnership with a nonprofit (501(c)(3)) with
community garden expertise is required to provide training, tools and assistance to
apartment residents. Partnership with the nonprofit with gardening expertise is required
throughout the life of the garden. If the community garden is abandoned, the required
landscaping must be installed. If the garden is located in the front landscaping, a
minimum of 5 feet of landscaping must be placed between the garden and the street.

CL:bjs Page 10 of 23
12. To accommodate the types of uses found in the C/1-1, LI, HI and MIC
districts, landscaping may be clustered to permit truck movements or to accommodate
other uses commonly found in these districts if the criteria in TMC Section 18.52.100.D
are met.
13. For NCC and RC zoned parcels in the Tukwila International Boulevard
District, the front landscaping may be reduced or eliminated if buildings are brought out
to the street edge to form a continuous building wall, and if a primary entrance from the
front sidewalk as well as from off-street parking areas is provided.
Section 9. Regulations Established. A new TMC Section 18.52.040, "Screening

and not less than 60% of the height of the material stored. The screens shall be
specified on the plot plan and approved by the Community Development Director. In
the MDR and HDR zones, outdoor storage shall be fully screened from all public
roadways and adjacent parcels with a high obscuring structure equal in height to the
stored objects and with a solid screen of exterior landscaping.
b. Ground level mechanical equipment and garbage storage areas shall
be screened with evergreen plant materials and/or fences or masonry walls.
c. Fences. All fences shall be placed on the interior side of any required
perimeter landscaping.
2. A mix of evergreen trees and evergreen shrubs shall be used to screen
blank walls.
3. Evergreen shrubs and evergreen trees shall be used for screening along
rear property lines, around solid waste/recycling areas, utility cabinets and mechanical
equipment, and to obscure grillwork and fencing associated with subsurface parking
garages. Evergreen shrubs and trees shall be pruned so that 18 inches visibility at the
base is maintained.
B. Visibility.
1. Design of new landscaping and maintenance of existing landscaping shall
consider Crime Prevention Through Environmental Design (CPTED) principals and
visibility for safety and views. Appropriate plant species shall be specified to avoid the
need for excessive maintenance pruning.

CL:bjs Page 11 of 23
2. Landscaping shall not obstruct views from or into building windows, the
driveway, sidewalk or street. Landscape design shall allow for surveillance from streets
and buildings and avoid creating areas that might harbor criminal activity.
3. Landscaping at crosswalks and other locations where vehicles and
pedestrians intersect must not block pedestrians' and drivers' views.
4. In general, deciduous trees with open branching structures are
recommended to ensure visibility to retail establishments. More substantial shade trees
or evergreens are recommended in front of private residences.
Section 10. Regulations Established. A new TIVIC Section 18.52.050,
"Significant Tree Retention," is hereby established to read as follows:
18.52.050 Significant Tree Retention
A. All significant trees located within any required landscape area that are not
dead, dying, diseased, or a nuisance species, as identified in the Tukwila Approved
Tree List, and that do not pose a safety hazard or conflict with overhead utility lines as
determined by the City or an ISA certified arborist, shall be retained and protected
during construction with temporary fencing or other enclosure, as appropriate to the site
and following Best Management Practices for tree protection (see TIVIC Chapter 18.54).
B. Retained significant trees may be counted towards required landscaping. For
each 2% of effective canopy cover provided by preserved trees incorporated into a
development plan, a 2% reduction in the minimum landscape requirement may be
granted. No more than 20% of the minimum landscape requirement may be reduced
for any one development. Approval is required per TIVIC Section 18.52. 100.
C. The area designated for protection will vary based on the tree's diameter,
species, age, and the characteristics of the planted area, and Best Management
Practices for protection shall be utilized (see TIVIC Chapter 18.54). Property owners
may be required to furnish a report by an ISA certified arborist to document a tree's
condition if a tree is to be retained. The Director may require that an ISA certified
arborist be retained to supervise tree protection during construction. Grade changes
around existing trees within the critical root zone are not allowed.
Section 11. Regulations Established. A new TIVIC Section 18.52.060, "Plant
Material Requirements and Tree Standards," is hereby established to read as follows:

Section 12. Regulations Established. A new TIVIC Section 18.52.070, "Soil
Preparation, Planting and Irrigation," is hereby established to read as follows:
18.52.070 Soil Preparation, Planting and Irrigation
A. Soil Preparation and Planting.
1. For landscaping in sidewalks and parking lots, or in limited areas of soil
volume, structural soils (Cornell University product or similar) must be used to a
preferred depth of 36 inches to promote tree root growth and provide structural support
to the paved area. Minimum soil volumes for tree roots shall be 750 cubic feet per tree
(see specifications and sample plans for CU-Structural Soils). Trees and other
landscape materials shall be planted according to specifications in "CU Structural Soils
— A Comprehensive Guide," as it now reads and as hereafter amended, or using current
Best Management Practices (BMPs) as approved by the Director. Suspended
pavement systems (Silva Cells or similar) may also be used if approved by the Director.
2. For soil preparation in bioretention areas, existing soils must be protected
from compaction. Bioretention soil media must be prepared in accordance with
standard specifications of the Surface Water Design Manual, adopted in accordance
with TMC Chapter 14.301 to promote a proper functioning bioretention system. These
specifications shall be adhered to regardless of whether a stormwater permit is required
from the City.
3. For all other plantings (such as large planting areas where soil volumes are
adequate for healthy root growth), soils must be prepared for planting in accordance
with BMP T5.13, "Post Construction Soil Quality and Depth," from the Washington
Department of Ecology Stormwater Management Manual for Western Washington (as it
now reads and as hereafter amended), regardless of whether a stormwater permit is
required by the City.
4. The applicant will be required to schedule an inspection by the City of the
planting areas prior to planting to ensure soils are properly prepared. Soil must be
amended, tilled and prepped to a depth of at least 12 inches.
W: Word Processing\Ordinances\Landscaping Code update-TIVIC 18.52 final 2-28-17
CL:bjs Page 15 of 23
5. Installation of landscape plants must comply with BMPs including:
a. Planting holes that are the same depth as the size of the root ball and
two to three times wider than the root ball.
b. Root balls of potted and balled and burlapped (B &B) plants must be
loosened and pruned as necessary to ensure there are no encircling roots prior to
planting. All burlap and all straps or wire baskets must be removed from B &B plants
prior to planting.
c. The top of the root flare, where the roots and the trunk begin, should
be placed at grade. The root ball shall not extend above the soil surface and the flare
shall not be covered by soil or mulch.
d. If using mulch around trees and shrubs, maintain at least a 6 -inch
mulch -free ring around the base of the tree trunks and woody stems of shrubs. If using
mulch around groundcovers until they become established, mulch shall not be placed
over the crowns of perennial plants.
B. Irrigation.
1. The intent of this standard is to ensure that plants will survive the critical
establishment period when they are most vulnerable due to lack of watering and to
ensure their long term viability.
2. All required plantings must be served by a permanent automatic irrigation
system, unless approved by the Director.
a. Irrigation shall be designed to conserve water by using the best
practical management techniques available, including BMPs, for daily timing of irrigation
to optimize water infiltration and conservation. These techniques may include, but not
be limited to: drip irrigation (where appropriate) to minimize evaporation loss, moisture
sensors to prevent irrigation during rainy periods, automatic controllers to ensure proper
duration of watering, sprinkler head selection and spacing designed to minimize
overspray, and separate zones for turf and other landscaping and for full sun exposure
and shady areas to meet watering needs of different sections of the landscape.
b. Exceptions to the irrigation requirement may be approved by the
Director, such as xeriscaping (i.e., low water usage plantings), plantings approved for
low impact development techniques, established indigenous plant material, or
landscapes where natural appearance is acceptable or desirable to the City. However,
those exceptions will require temporary irrigation until established.
3. All temporary irrigation must be removed at the end of the 3 -year plant
establishment period.

"Maintenance and Pruning," is hereby established to read as follows:
18.52.080 Maintenance and Pruning
A. Any landscaping required by this chapter shall be retained and maintained by
the property owner for the life of the development in conformance with the intent of the
approved landscape plan and this chapter. Maintenance shall also include keeping all
planting areas free of weeds and trash and replacing any unhealthy or dead plant
materials.
B. Green roofs or rooftop gardens shall be maintained to industry standards and
any dead or dying plant material replaced.
C. Pruning of trees and shrubs is only allowed for the health of the plant material,
to maintain sight distances or sight lines, or if interfering with overhead utilities. All
pruning must be done in accordance with American National Standards Institute (ANSI)
A-300 specifications, as it now reads and as hereafter amended.
D. No tree planted by a property owner or the City to fulfill landscape
requirements, or any existing tree, may be topped or removed without prior approval
from the City. Any tree topped or removed without approval shall be subject to code
enforcement action per TMC Chapter 8.45 in addition to the requirements of TMC
Section 18.52.110, "Violations."
E. Private property owners shall collect and properly dispose of all landscaping
debris. Private property landscaping debris shall not be placed or blown into the public
right-of-way for City collection. Violations will be subject to code enforcement action per
TMC Chapter 8.45.
F As trees along the street frontages mature, they shall be limbed up, using
proper ISA pruning techniques, to a minimum height of 8 to 18 feet depending on
location of tree (over sidewalk, adjacent to road, etc.) to allow adequate visibility and
clearance for vehicles. Trees may be pruned to improve views of signage and
entryways by using such techniques as windowing, thinning, and limbing up; however,
no more than 1/4 of the canopy may be removed within any 2-year period. All pruning
shall be done in accordance with ANSI Standard A-300 specifications, as it now reads
and as hereafter amended.
G. Trees may only be pruned to lower their height to prevent interference with an
overhead utility line with prior approval by the Director. The pruning must be carried out
under the direction of an ISA certified arborist. The crown shall be maintained to at
least 2/3 the height of the tree prior to pruning. Otherwise, trees shall not be topped.
