RE: File #11- 104429- 00 -AD; RESPONSE LETTER
Dumas Bay Center, 3200 SW Dash Point Road, Federal Way
Dear Mr. Ikerd:
In response to your tree removal request dated November 14, 2011, we requested that you submit a maintenance
and revegetation plan prior to the removal of trees located at the Dumas Bay Center. This plan would be in
accordance with the newly adopted Shoreline Master Program (SMP). The City received your plan on December
9, 2011, and finds your proposal fulfills the intent of Federal Way Revised Code (FWRC) Shoreline Management
section 15.05.080 (3)(e), which states that the director may allow removal of vegetation in a vegetation
conservation area where an applicant agrees to replacement plantings that are demonstrated to provide greater
benefit to shoreline ecological processes.
You propose to cut down leaning, dead, dying, or diseased trees and leave stumps and roots in place for
stabilization, in addition to cutting down saplings to one foot high stumps. Stumping will provide stabilization to
the slope while new plantings take root, with additional annual maintenance for the next four years to keep sucker
growth on the stumps from overshadowing the new plantings. Lastly you propose to replant the area with vine
maple and smaller native species to provide greater stabilization to the area by creating a thicker root mass, which
reduces the chances of erosion by slowing the runoff. Replanting with native species will also provide a new food
source and habitat for local wildlife.
Based on analysis of submitted information, the City finds that tree removal and revegetation within the
vegetation conservation area is acceptable. Therefore, landscaping activity is subject to the following conditions:
CONDITIONS
1. Any work within the vegetation conservation area is consistent with FWRC Interpretation #10-0 1 and is
limited to the use of hand tools (including hand power tools).
2. Continued maintenance to the area shall stay consistent with your maintenance plan.
If you have any further questions, feel free to contact Alexa Heidrich, Planning Intern, at 253 -835 -2622 or by

RE: File #1 1- 1 04429- 00 -AD; TREE REMOVAL REQUEST
Dumas Bay Center, 3200 SW Dash Point Road, Federal Way
Dear Mr. Ikerd:
On November 2, 2011, the City of Federal Way's Department of Community and Economic Development
received your request to implement a maintenance management plan to recover two sections of view
corridor at the Dumas Bay Center, located on parcel #122103 -9146. As an I.S.A. Certified Arborist you
identify two sections of young trees as vulnerable to disease and decay, and recommend removal of these
two sections to ensure integrity of the slope and to reclaim views of Puget Sound.
The subject property is zoned Residential 15.0 (RS) and is located within a "natural environment"
designation pursuant to the city's Shoreline Master Program (SMP). The proposed removal is also
located in a critical area, pursuant to maps produced by the City, and therefore is subject to our
geologically hazardous areas section of Federal Way Revised Code (FWRC).
Interpretation #10-0 1 of FWRC addresses temporary intrusions into environmentally sensitive and
associated buffer areas for vegetation maintenance. It states that trees located in a critical area may be
removed if granted Director's approval. Criteria evaluated in your proposed action plan were consistent
with Interpretation #10-0 1, and demonstrated that the removal of the identified sections of trees did not
adversely affect the slope or natural environment. Additional consideration was given due to your
concerns that the young trees, which have filled in the previously maintained corridor, will likely develop
decay and are structurally unsound, which could create a potential erosion effect on the slope. Lastly,
pursuant to the Interpretation, consideration for restoration of the Puget Sound view corridors is also
given. It is important to note that any work within the hazardous area would be limited to the use of hand
tools (including power tools). Additionally, the approval stipulated that you would perform any
reasonable mitigation efforts the City determines necessary to restore or maintain the health of the slope.
NEW SHORELINE MASTER PLAN (SMP)
The City has been working to update the SMP and within the month will adopt the newest version. Due to
the imminent timing of the revised SMP, it is necessary to acknowledge the impact the updated program
would have on your proposal. The 2011 revised SMP implements a vegetation conservation requirement
within the l 00 -foot setback from the ordinary high water mark. It is likely part or all of your proposal
would become subject to regulations of the vegetation conservation area. Vegetation removal is permitted
within the setback, with Director's approval; however, the applicant must provide a maintenance and
revegetation plan that demonstrates a greater benefit to the shoreline than adherence to the vegetation
conservation standard.

With consideration for the intent of the new SNIP, the City would like to request a maintenance plan,
which includes a plan for revegetation that provides greater benefit to the area, prior to the approval of
tree removal.

Subject: Tree removal request
Dumas Bay Centre located at 3200 Dash Point Road is a combined City Conference
Center and Theater situated on a public park setting. One of the main features that draw
conferences as well as the general public to this facility is the panoramic view of Puget
Sound and the Olympic mountains. Over the past several years many native trees have
seeded themselves and now a thick grove of young trees have grown up to block the view
completely on the north side of the site. A section of the south is also filling in and
reducing the view that was present when the facility was purchased in 1993.
Historically the Sisters of Visitation kept the corridors in question trimmed to preserve
the views. After the City purchased the facility they continued to trim for view until a
past Superintendent decided to no longer trim.
Staff now realized that not only are these views important to the marketing of the facility
but they are important to the general public who needs a safe public place to come and
experience a great panoramic view of the Sound, Olympic mountain range and many
wildlife species.
Conditions:
The locations of concern include two sections shown on the attached photo where young
trees have grown up to block the original view. The primary species of concern consist of
red alder-, Alnus rubra, big leaf maple; Acer macrophyllum with some bitter cherry;
Prunus emarginata and scouler willow; Salix hookerina mixed in. These trees are
growing on the western property slope overlooking Dumas Bay. There is a rock bulkhead
in place to protect the base of the slope from wave action. There are also sections of large
mature, big leaf maple, alder and Douglas fir on this same slope that are helping to
stabilize the slope and give a visual benefit to the setting. These mature tree groves also
provide important wildlife habitat for a variety of birds and mammals and will be kept
intact.
Concerns:
1. Loss of two significant view corridors for both the users of the conference center
and the park grounds which are open to the public.
2. Some of the young trees have been damaged and will one day fail from disease
and decay.
3. Many of the young trees that have filled in the view corridors, are multi stemmed
and as such will develop decay pockets. RECEIVED

4. The large amount of young trees growing close together has created a situation
where they have grown quickly competing for light and become spindly which in
a few years sets them up to become more prone to blow down. Any uprooting
from a blow down opens up a new potential erosion condition.
Request:
Approval to implement a Maintenance Management plan to recover two sections of view
corridor and then maintain these areas on an ongoing basis.
Action plan:
The Parks Department proposes:
1. Cut down leaning, dead, dying or diseased trees on the slope but leave the stumps
and roots in place for stabilization.
2. Cut down all the young alder, maple, cherry and willow in the attached marked
corridors to a one foot high stump. Stumping will allow for sucker growth to
occur on these particular varieties; which will keep the established roots alive for
stabilization. A routine Maintenance program will keep this sucker growth in
check so they don't grow too large and block the views again. The trees closest to
the top of the slope will be cut and chipped back onto the slope and the remainder
will be cut up and scatter to decompose.
3. Prune a few select limbs on the existing mature maples, fir and alder as needed for
health and view enhancement,
Prune trees between these two viewpoints

I.S.A. Certified Arborist #PN1942A
Subject: Dumas Bay Centre — maintenance and re- vegetation plan
This is a follow -up to a tree removal request which has been assigned a file number of:
#11- 104429- 00 -AD. The Federal Way Department of Community and Economic
Development have requested that a maintenance and re- vegetation plan be submitted
before final approval is given prior to any vegetation removal.
Maintenance plan:
The Parks Department proposes:
1. Cut down leaning, dead, dying or diseased trees on the slope but leave the stumps
and roots in place for stabilization.
2. Cut down all the young alder, maple, cherry and willow in the attached marked
corridors to a one foot high stump. Stumping will allow for sucker growth to
occur on these particular varieties; which will keep the established roots alive for
stabilization until new proposed plantings can establish. As the new plants are
establishing Park staff will cut back the sucker growth from the stumps at the end
of each season for at least 4 years or until the new plants have naturalized. Once
the new plants have established, the stumps will be flushed cut. In addition a few
select limbs on the existing mature maples, fir and alders will be pruned to
remove damaged or decaying limbs.
Re- vegetation plan:
The Parks Department proposes:
1. Improving the slope area where the tree removal will occur. Currently there are
areas where very little understory have developed as the trees in question are
producing a lot of shade. By removing the trees in question and re- planting with
smaller native species the slope will have more chance to fill in and provide added
stabilization with a thicker root mass. The development of a heavier understory
can provide new habitat for the local wildlife, provide a new food source and
reduce the chances of erosion by slowing the runoff.
2. The proposed species for re- vegetation will include the following native plants:
Acer circinatum — vine maple
Mahonia aquifolium — Oregon grape (tall variety)
Mahonia nervosa - Oregon grape (shorter variety)
Gaultheria shallon — salal
3. See attached planting plan.
