LANDSCAPING
Perimeter landscape includes an 8’ planter strip with a combination of evergreen and deciduous
trees, and ground cover. Parking lot landscaping require landscaped islands, and no parking stall
be located more than 50 feet from a tree.
Per Chapter 18.55.020.A YMC
a dense sight barrier is required to provide a physical buffer to significantly separate conflicting
uses and land use districts. The property to the south is currently a church and the property to
the west is currently residential therefore a dense sight barrier must be created following Chapter
18.55.020 A guidelines:
All plant materials and living groundcover must be selected and maintained so that the entire
landscape area will be covered within three years.
Any combination of trees, shrubs, fences, walls, earthen berms and related plant materials or
design features may be selected; provided, that the resultant effect is sight-obscuring from
adjoining properties.
A minimum of 15 feet of width shall be required when dense site barrier landscaping design is
utilized.
Parking lot landscaping can be found under 18.55.020 D. YMC and is listed in this section as
well:
•Parking areas shall have a minimum of at least 24 square feet of landscape development
for each parking stall proposed.
•Each area of landscaping must contain at least 100 square feet of area and must be at
least six feet in any direction.
•Live groundcover shall be provided throughout each landscaping area. Groundcover may
be a combination of shrubs and trees that provide the desired effect of providing visual
relief and green space within the parking area. Groundcover shall be selected and
maintained so that the entire landscaped area will be covered within three years
Trees shall be spaced 35 feet on center starting 15 feet from the property line. Tree spacing may
be adjusted to allow unobstructed sight distance on either side of a driveway and at street
intersections. Tree spacing may also be adjusted when in conflict with luminaire poles.
If stormwater retention/detention areas are included it must have the proper landscaping
following Chapter 18.55.020 E YMC:
The floor and slopes of any stormwater retention/detention area shall be planted in vegetation
that is suitable and will thrive in hydric soils.
The landscaping of the stormwater facility shall be incorporated with all on-site landscaping.
When biofiltration swales and ponds are used in any development other than residential
subdivisions, they shall be incorporated into overall site design through one of the following
means listed in order of preference:
o Locate biofiltration swales, pond, or other approved biofiltration systems at the side or
rear of the lot and incorporate as part of a landscape screen.
o Locate biofiltration swale, wet pond, or other approved biofiltration system within the
paved parking or service area.
o Locate swale along the front edge of the property. Incorporate landscaping and
screening to visually enhance the swale.
o If the biofiltration swale is located and/or designed as a positive landscaping feature with
an approved design and plant materials, it may be counted as part of the required site
landscaping

GENERAL LANDSCAPE NOTES
1.Contractor is responsible for obtaining all necessary permits from the appropriate agency prior to commencing work.
Contractor shall contact Line Locators (811) a min. of 48 hours prior to any digging or trenching. If there are any
discrepancies with existing lines and landscaping, it is the contractor's responsibility to contact the landscape architect and
request a site visit to address the conflicts. Contractor shall comply and conform to any and all local and state codes for
work, schedules and any other project related requirements.
2.Contractor shall coordinate directly with the landscape architect for all landscape related issues, concerns, inspections and
approvals. Contractor shall provide the landscape architect with a written request for a site visit to address any related items.
3.Scope of work shall include any and all specified and unspecified but related incidental work to achieve the design indicated
on the landscape plans. All labor, materials, subcontractors, equipment, and related incidental items shall be supplied and
installed to achieve a complete project, unless directed otherwise by the general contractor or landscape architect.
4.Contractor to verify all sub grades are set below required amendments to insure the finished grade will match what is
intended by civil or drainage design. All sub grades and finished or final grades shall be graded to drain to the designed
drainage system with positive drainage away from all structures.
5.Grade Preparation:
a.Slopes used for grass plantings or turf shall be less than 3:1 or 33 percent. Otherwise plantings should not require
mechanized mowing equipment. Any invasive / toxic vegetation shall be removed and treated with herbacide (hand
applied to minimize treatment to specific plant) prior to any new planting. Native vegetation shall not be disturbed.
Soil Preparation.
a.Where soils are compacted and in informal grassy play areas, planting beds should be deep tilled to a depth of at least 12
inches. Soils shall be enhanced through the addition of the following materials: bark and forestry by-products, organic
matter such as composted yard waste, organics and other amendments as needed through a soils test. Soils that meet a
balanced PH between 6-8PH, do not required amending. Where Pit Planting, see planting detail for planting ring sizes
and depths. Scarify the edges of planting pits to encourage root expansion.
b.On project sites where topsoil is limited or nonexistent, a minimum depth of 6 (six) inches of sandy loam topsoil should be
tilled into the soil to a depth of 12 inches through all planting areas with compacted soils.
c.For all newly planted areas, three cubic yards of composted organic matter per 1,000 square feet of landscape area
should be added to a depth of four inches to the top of the soil and Tilled in.
d.Seeded areas shall be fine graded and rolled. New Soil depths in lawn areas shall be 4 Inches.
e.Native undisturbed areas with new trees shall be pit planted per tree planting details.
f.In order to utilize on site Top Soil, contractor shall submit a soil test showing the PH (acid) level of existing Top Soil on
site. A ziploc type bag of soil can be delivered to Spectra Lab in the Tacoma Tideflats - 2221 Ross Way, Tacoma, WA
98421 or a similar testing lab to measure PH level in soils.
6. Mulching of Newly Planted or Replanted Areas.
a.Mulches must be applied to the following depths: a minimum 3 (three) inches over bare soil, and two inches where plant
materials will cover.
b.Mulches must include organic materials, such as wood chips and shredded bark.
c.Nonporous materials, such as plastic sheeting, shall not be used in any area of the landscape because of down-slope
erosion and potential soil contamination from herbicide washing.
d.Mulch should be applied regularly to and maintained in all planting areas to assist soils in retaining moisture, reducing
weed growth, and minimizing erosion.
7. Contractor shall field layout all plant material and contact the landscape architect for a site visit to approve the layout. Any
field modifications shall be done by the landscape architect prior to planting.
8. Contractor shall immediately notify the landscape architect of any poor drainage condition in landscape areas. No standing
water shall be permitted in any landscape areas - either on the surface or below the topsoil. The landscape architect shall
coordinate the drainage solution with the general contractor and civil engineer. Once the concerns have been remedied planting
shall commence.
9. All groundcover to be planted in a triangular spacing formation, equal in all directions to the centers of the groundcovers in
distances indicated in the legend. Contractor shall verify all quantities of groundcovers by area calculations and spacing
requirements.
10. Landscaping is to be per plan. Plant substitutions due to availability or otherwise will be allowed only with landscape
architect, owner and agency approval. Any substitutions will be with material of similar size, growth characteristics, and quality.
11. All trees must be staked as necessary so as to maintain material in a healthy, vigorous growing condition.
12. Landscaping shall be installed in a professional workmanlike manner that is consistent and accepted throughout the
industry. All landscape and irrigation work shall be performed by experienced persons familiar with scope of project.
13. All landscape material and labor is to be guaranteed for a period of one full year from the time of completion.
14. When planting 'Balled and Burlapped' product, remove all burlap, string & wire from any B&B plant material, cut and remove
jute strings. Gently place in tact Rootbal into planting pit. If rootball breaks or is not solid - the plant is unacceptable and shall
be replaced.
15. Street trees shall be high branching with canopy that starts at least 6' above finish grade.
16. All plant I.D. tags are to remain on the plant material until final inspection has been completed. Once approved all plant I.D.
tags shall be removed and discarded appropriately.
17. Trees shall be cared for in accordance with the American National Standards Institute (ANSI) standard practices for trees,
shrubs and other woody plant maintenance (ANSI 300) in order to allow them to reach there mature height and form.
18. Pruning of street trees shall be performed per the ANSI 300 standards so as to maintain the natural form of the tree,
encourage vigorous growth to a mature spread and height, and avoid weakening the tree to create a hazard. Street trees shall
not be topped pollarded, or otherwise pruned in a manner contrary to these goals, unless there is no practicable alternative that
would preserve essential utility services.
19. IRRIGATION: Plant material selected is drought tolerant or native species. A permanent irrigation system shall be
installed per plans.
It is recommended to install the landscaping in the Spring (February - April) or Fall (October - December)when dormant but
before hard freeze.
TEMPORARY IRRIGATION
The project proponent shall ensure that a minimum of one (1) inch of water is supplied each week to the restoration area
between May 1 and October 15 for a least the first two years following initial planting. The calculated amount of required
water shall include both natural rainfall and temporary irrigation.
