This Planting Plan is reqs iced b
2 trees be replanted in its place. -She
breast height for deciduous trees or 6
trees are to be replaced.
The 4 trees that were removed were of significant size with large spreading canopies. These
trees provided significant slope protection from rainfall and contributed to ground water
absorption thus reducing erosion and ground water flow. It will take many years for the 8
mitigation trees to replace the slope protection and ecological functions that the 4 trees previously
provided. In my opinion, additional plants should be planted to protect the bare soil left on the
slope after the removal of the trees.
Because the 4 trees have been removed, it is difficult to tell exactly how much of the slope
was protected by the trees; however, it is safe to say that any planting will take many years to
replace their benefits. Given the bare soil and steep slope that was left after the tree removal, the
goal of any mitigation plan should be to cover the bare soil with plants and mulch: to -protect it
from further erosion and eventually replace the benefits that were lost with as much vegetation as
possible. Therefore, the following Planting Plan is recommended:
Plant List:
® 6 — 6' Shore Pine, Pinus contorta var. contorta (As shown on plan)
2 — I "caliper Kousa Dogwoods, Cornus kousa ehinensis (As shown on plan)
9 — 2 gallon Red Twig Dogwood, Cornus sericia (In groups of 3 10 feet apart as shown on
plan)
75-lgallon Kinnikinnik, Arctostaphylos uni-ursa (In groups of 10 as shown on plan)
* 75 — 2 gallon Sword fern, Polystichum munitum (In groups of 10 as shown on plan)
Planting Notes
1. Plants shall meet or exceed National Landscape Standard Specifications.
2. Plants shall be full, vigorous, and healthy with no visual defects.
3. Photos of plants shall be sent to Consulting Arborist before delivered to site for pre -
approval. Plants shall be inspected and approved by the Consulting Arborist on the site
before planting.
4. Contractor shall meet with Consulting Arborist for pre -construction meeting to confirm
plant layout and installation procedures.
5. Contractor shall follow the planting instructions on the attached Planting Detail.
6. The entire planting bed shall be covered with 3 inches of approved compost. Compost
shall meet the most current version of ASTM D2974 "Test Methods for Moisture, Ash,
and Organic Matter of Peat and Other organic Soils," and TMECC 05.07A "Loss -On -
Ignition Organic Matter Method". An analysis of the compost shall be submitted to the
Consulting Arborist and approved before it is delivered. An explanation of this soil
amending method is found in Client Assisted memo #531 from the Department of
Planning and Development. Go to www.seattle.gov/dpd.
7. The soils in the planting beds shall be scarified to a depth of 8 inches into sub -grade to
thoroughly mix the compost into the existing soil, either by hand onwith,a.sll,,-
excavator. The Consulting Arborist shall inspect and approve the depth of the scarified
soils.
8. Immediately after plant installation, contractor shall breakup all compacted soil adjacent
to and between all plants, from landscape work, to a minimum depth of 6 inches and

immediately cover the soil between plants with 3 inches of arborist woodchips. Mulch
shall be pulled 3 inches away from base of all plants.
9. Hand water all plants immediately and thoroughly.
10. Consulting Arborist shall be onsite when planting begins to approve plants and confirm
installation process. He shall approve the proper completion of the planting and report to
the owner and City.
Maintenance Plan
1.The contractor shall hand watered all plants once per week during the first growing season
which include the months of April through September.
2. The contractor shall hand watered all plants once every 2 weeksduring the second year.
3. All mortality shall be replaced immediately during the first growing season:
4. The Consulting Arborist shall inspect the planting once per month during the first growing
season and twice during the second growing season and report on establishment and
mortality immediately to the owner.
5. The contractor shall maintain 3 inches of Arborist's mulch over the entire planting site up
though the end of the first year.
6.The Consulting Arborist and property owner (Strands) shall report the progress and final
establishment of the plantings at the end of the first and second growing season for final
acceptance and approval.
Landscape Planting Detail
Attached is the Planting Detail that
illustrates the specified method for tree, shrub
and groundcover installation.
Landscape Planting Plan —
Attached is Landscape Planting Plan that
generally illustrates the layout of the plants
specified. This drawing is conceptual and
adjustments in the field will be required to
avoid the stumps of cut trees and other
existing plants.

include Red Alder, Ulnus rubra, Quaking Aspen, Populus tremuloides and some type of wild elm
variety, Ulmus, spp. Technically, I measured only 7 of the 34 trees to be. considered significant
by the city, meeting or exceeding 6 inches in diameter. They are growing as a large group of trees
with a very dense canopy and approximately 60 feet tall. They all appear to be healthy and

growing well although competing for the limited space they are in. Seethe attached site map for
their location.
In the Strand/ Hathaway Meeting Letter dated June 14, 2010, on the second page, Part B, it
states, "In a conversation on May 27th with the Strands Attorney Mr. Mendez, he inquired about
what would be necessary to perform work on the deciduous trees at the northeast corner of the
Stand's parcel as well as the duration of the Strand's conditional use permit. First, the
conditions of CU -08-40 still apply for the deciduous trees and each condition must be satisfied:
+ A management plan must be submitted for review and approval (Condition 91);
• If there are documented hazard trees, they could be removed but otherwise the management
plan should describe what arboricultural techniques are proposed for tree cutting and
maintenance (Condition #2)
• Any trees removed must be replaced per Condition #3-5.
I am assuming that `perform work' onthese trees refers to complete removal or pruning to
allow for increased views.
It is my understanding that the Strands, the owner of the trees are not requesting that they be
removed. It also appears that the city requires that the trees be considered hazardous to be eligible
for removal. They are not hazardous in my opinion so do not qualify to be removed for that
reason.
Another option to improve the view would be to prune or thin the trees or severely top the
trees. In my opinion, neither of these options is viable.
Pruning or thinning the tree canopies would do little if any good and would quickly regrow
and fill the opening left by the pruning. Pruning or thinning in this regard refers to selectively
cutting back lateral limbs.
Topping trees like this is never recommended because it ruins the structure of the tree,
leaves a large pruning wound open to disease and insects and stimulates excessive new growth.
This growth is usually denser than what was removed and is susceptible to failure because of poor
attachment. It would have to be repeated continually over the coming years and the trees would
slowly decline and die over time, and their appearance would be increasingly objectionable over
time.
Therefore, I do not recommend that the trees be pruned or topped. If the city allows the
removal of the trees even though they are healthy and the Strands make that request, then a tree
removal and mitigation plan will be submitted.
A follow-up to this report is to provide an Appraisal for the landscape value of the 4 trees
that were removed without authorization. This value is to determine compensation for the loss of
the trees that were not considered hazardous but rather were an amenity to the Strand property.
Let me know if you have any questions regarding this planting plan for the Strand property.
