12-104759f � CITY OF Federal Way October 1, 2013 Mr. Sam Keller, Facilities Engineer Archbishop Brunett Retreat Center 4700 SW Dash Point Road Federal Way, WA 98023 CITY HALL 33325 8th Avenue South Federal Way, WA 98003-6325 (253) 835-7000 www. cityofiederalway.. com FILE Re: File #12-104759-00-AD; RESPONSE TO INQUIRY/APPROVAL Archbishop Brunett Retreat Cener; 4700 SW Dash Point Road, Federal Way Dear Mr. Keller: The Community and Economic Development Department has received your request to implement a vegetation management plaft'fonthe bluff areA located,at-the above-refereneed addr-ess-.�The. subject site is located within a designated geologically hazardous area and shoreline planning area. Therefore, removal does not qualify as an exempt action listed in Federal Way Revised Code (F)ArRC) 19.120.030. The department has issued Interpretation #10-01 that provides clarification of the proper procedure, application materials, and decisional criteria for vegetation removal within identified critical areas. DECISION Proposed tree removal, tree pruning, removal of invasive vegetation (blackberries) and replanting with native tree species, and ongoing vegetation management through the year 2023 as specified in the submitted August 7, 2013, report entitled "Vegetation Management Plan" prepared by Washington Forestry Consultants is hereby approved subject to the condition, and per the findings and conclusions provided below. CONDITION OF APPROVAL 1. Per FWRC 15.05.090(3)(e), the area within the required shoreline setback, which is a minimum of 50 feet landward from the ordinary high water mark, shall be maintained as a vegetation conservation area and no more than 15 percent of the area with existing native shoreline vegetation shall be removed and a minimum of 80 percent of existing native trees shall be retained. DECISIONAL CRITERIA Planning Division staff reviewed the request and provided a bulleted response to each of the director's decisional criteria below. Mr. Sam Keller Page 2 October 1, 2013 The proposed activity will not adversely affect water quality. Tree roots will not be disturbed and adequate erosion protection to the slope will be retained. Further, the decision has been conditioned to allow removal via hand tools only to limit impact on surrounding soils. 2. The proposed -activity will not destroy nor damage a significant habitat area. The bluff area of the site iAeavily forested and will contain a large number of trees, even after vegetation maintenance is completed. In addition, the applicant is proposing to plant native trees and shrubs that will require less maintenance in the future and therefore, result in less site disturbance of the habitat area over time. 3. The proposed activity will not adversely affect drainage or stormwater retention capabilities. Tree stumps and root systems will be retained, so work will not alter the drainage course or contribute to drainage and stormwater retention failures. 4. The proposed activity will not lead to unstable earth conditions, nor create erosion hazards. The tree removal is limited in scope. Tree stumps along with the remaining vegetation will stabilize potential erosion. 5. The proposed activity will not be materially detrimental to any other property, nor to the city as a whole, including the loss of significant open space. The tree work is not proximate to adjacent properties and as tree roots and stumps are being retained and replanting is proposed, the result of the tree work will not contribute to loss of open space. Proposed work within the designated 50-foot shoreline setback area, which coincides with Zone 3 as identified in the vegetation management plan, is limited to removal of hazard trees, which is consistent with the applicable vegetation management standards in FWRC Title 15, "Shoreline Management." 6. The proposed activity is necessary to: a) maintain existing pathways and landscaping, ensure the health of existing vegetation, achieve limited pruning to allow for view maintenance, reduce tree mass or redirect tree growth, or similar purposes; and/or b) the proposed activity is necessary to minimize potential impacts from dead, dying, diseased, or otherwise dangerous or nuisance vegetation. The proposed tree removal, crown reduction, and removal of invasive species is proposed to address many of the above issues. While an overarching goal appears to be view preservation, the removal of invasives and replanting with natives of a smaller stature requiring less maintenance in the future will result in more stable habitat on the bluff. In addition, trees that pose a potential risk to the staircase and its users will be pruned. 7. The proposed activity does not require review under the State Environmental Policy Act (SEPA). The department concludes that this activity is exempt from SEPA review. 8. The proposed activity is consistent with the requirements of FWC Chapter 19.120, "Clearing, Grading, and Tree and Vegetation Retention. " The proposed vegetation management is consistent with the purpose statement and regulations of FWRC Chapter 19.120.

You noted that maintenance of the vegetation is of interest to preserve the view from the upper slope of the property. You also submitted two photos showing the existing vegetation. Because the trees and vegetation you wish to remove are located within an environmentally sensitive area (geologically hazardous area) and the designated shoreline environment, director approval is required for vegetation removal and maintenance. In order to review the trees and vegetation proposed to be removed/trimmed, please provide a professionally prepared arborist's report that identifies the location, number, type, condition, and size of trees, and general description and location of vegetation to be removed; the method of removal (noting if any stumps are to be retained); clarify if any replacement vegetation is proposed; and identify how they proposed tree removal/ trimming is consistent with the provisions of Director's Interpretation 10-01 (enclosed). Specifically address how the tree and vegetation removal and any replanting will be done so as to preserve the integrity of the slope. You mention in your letter that ongoing maintenance of the vegetated slope is important. Therefore, it is advisable that you have an arborist prepare a long-term vegetation maintenance plan for city review. Upon review and approval of a vegetation maintenance plan, ongoing maintenance that falls within the parameters of the approved plan may be done on an ongoing basis without need of subsequent requests for vegetation maintenance in the area covered by the approved plan. Please use the enclosed Resubmittal Information Form and reference file #12-104759-AD. The city will reply in writing to the request to trim/remove trees and vegetation once the submitted information has been reviewed. Please do not hesitate to contact me at janet.shull@cityoffederalway.com, or 253-835-2644, if you have any questions about this letter. Sincerely, ti ! net Shull, AICP, CSBA, LEED Green Associate enior Planner Enc: Resubmittal Form Interpretation 10-01 Doc LD 62497 RESUBMITTED AUG 2.3 2013 CITY OF FEDERAL WAY CDS - Vegetation Management Plan - ARCHBISHOP BRUNETT RETREAT CENTER 4700 SW Dash Point Road Federal Way, WA 98023 Prepared for: GeoEngineers, Inc. Prepared by: Washington Forestry Consultants, Inc. Date of Report: August 7, 2013 City of Federal Way Ref. #: 12-104759000-AD Introduction and Scope of Work I have completed a review of the trees and vegetation east of the Archbishop Brunett Retreat Center project. The purpose of the review was to develop a plan for management of the trees and vegetation on the slopes west of the project. This plan is a re -submittal and is prepared in response to the City of Federal Way letter of October 29, 2011. The report addresses all of the requirements of Interpretation #10-01. Specifically we were to evaluate alternatives (prioritized in order of importance) that: ■ Enhance the view of Puget Sound and the Olympic Mountains from the Archbishop Brunett Retreat Center • Protect slope stability and minimize disturbance of soils • Enhance wildlife habitat values ■ Protect healthy, long-term trees • Provide long-term solutions to slope and tree management issues ■ Minimizes future tree management and site disturbance Methodology A map and inventory (Appendix II and III) of the existing tree conditions on the slope were prepared by Synthos, LLC and provided to Washington Forestry Consultants, Inc. (WFCI). The information (collected by the owner) included tree number (tag placed on tree), tree species, diameter at breast height, and the number of stems. The locations of Archbishop Erunett Retreat Center— Vege.taLioil Management Plan these trees were mapped using a Trimble GeoXH 6000 GPS. A map with plotted tree locations and a spreadsheet inventory was provided to WFCI. I did not find that the property lines were marked in the field, so the assessment assumes that the GPS's tree locations are all on the subject property. WFCI then evaluated the trees, vegetation, and other site conditions and discussed the slope and vegetation conditions with GeoEngineers to prepare recommendations for vegetation management. GeoEngineers was also on site to complete a geologic reconnaissance of the slope and assist in identifying areas where vegetation modifications could be accomplished without increasing the risk of slope instability. The slope was divided into 3 zones along a specific elevation (Appendix I and 11), and a prescription for management was developed to accomplish the tree and vegetation management for protection of views and the slopes using these zones. Pruning and tree removal prescriptions were then developed. The Synthos, LLC tree list (Appendix III) is attached. Tree by tree prescriptions are provided in the 'Prescriptions' section of the report where necessary. All prescribed work is within the ANSI A300I standards for proper pruning. Existing Conditions The trees on the upper portion of the slope have been managed for view protection in the past. The number of cuttings is unknown, however it has occurred more than 2 times based on viewing of larger trees near the middle slope. Photo A. Typical view from top of bank. Shows heavy stocking of bigleaf maple sprouts. 1 American National Standards Institute — ANSI A300 (Part 1). Pruning for Tree Care Operations — Tree Shrub and Other Woody Plant Maintenance — Standard Practices (Pruning). American National Standards Institute, Inc. Washington, D.C. Washington Forestry Consultants, Inc. 2 Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan Management Zones The slope is divided into 3 zones for management, which will be titled Zone 1 (upper), Zone 2 (middle), and Zone 3 (lower). The following list summarizes the approximate elevations of the breaks between zones. It is important to note that the slopes in Zone 1 are gentle - ranging from 5% to 20%. There is a distinct break between Zone 1 and Zone 2, where slopes increase to 30 to 70% (in short stretches). The slopes in Zone 3 range from 50 to 80% in short stretches. Area Elevations Top of Bank 175 ft. a.s.l. Zone 1 (Upper) 175 ft. to 140 ft. Zone 2 (Middle) 140 ft. to 90 ft. Zone 3 (Lower) 90 ft. to the beach Zone 1 - Existing Conditions The upper slope is predominantly small trees and shrubs. Bigleaf maple (Acer macrophyllum), Pacific madrone (Arbutus menziesii), Douglas -fir (Pseudotsuga menziesii), and bitter cherry (Prunus emarginata) dominate the area. Most have been cut just above the groundline in the past, or topped at 6 to 12 ft. in height. The shrub layer is predominantly western hazelnut (Corylus cornuta), oceanspray (Holodiscus discolor), sword fern (Polystichum munitum), and Himalayan blackberry (Rubes armeniacus). The trees and vegetation occur as scattered individual stems and clusters, with contiguous patches of Himalayan blackberry in areas. Photo B. Shows typical Zone 1 vegetation. Washington Forestry Consultants, Inc. 3 Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan Zone 2 - Existing Conditions Zone 2 starts at a topographic break. The steepness of the staircase is noticeably different, as it goes straight down slope for about 50 feet, then jogs south to a hairpin turn, then down to the beach. Zone 3 starts at about this hairpin turn in the staircase. The tree species in Zone 2 include bigleaf maple, Scouler willow (Salix scouleriana), European white birch (Betula pendula), red alder (Alnus rubra), Douglas -fir, western red cedar (Thuja plicata), and western hemlock (Tsuga heterophylla). They range in size from 2 to 24 inches DBH. Many of the bigleaf maples are multi -stemmed from previous cutting. Photo C. View of tree #69, a bigleaf maple. Shows how the trees are numbered as well as the density of shrub and tree cover in Zone 2. Many of the trees in the upper part of Zone 2 have been topped in the past - most to a height of about 5 to 30 ft. above the groundline. The bigleaf maples and Scouler willows, in particular have resprouted vigorously and now are multi -stem trees. Red alder has naturally seeded into mineral soil in the gaps and now occurs as saplings to pole sized trees (2 to 8 inches DBH). Tree size in Zone 2 is quite irregular, as is the stocking. The stocking ranges from open to dense stands of smaller trees (mostly red alder). Most older trees are pistil -butted, which is typical of trees that grow on steep slopes. The understory shrub layer is dense with salal (Gaultheria shallon), oceanspray, baldhip rose (Rosa gymnocarpa), swordfern, and western hazelnut being the predominant species. Washington Forestry Consultants, Inc. 4 Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan Zone 3 - Existing Conditions This zone is heavily stocked. with red alder and bigleaf maple ranging from 4 to 14 inches DBH, which scattered larger trees. A few native conifers (Douglas -fir) also occur. The trees range from young to older trees and most all are pistil -butted. Photo C. View of Zone 3 from beach. The understory shrub layer in Zone 3 includes a dense layer of western hazelnut, Indian plum (Oemleria cerasiformis), oceanspray, salal, swordfern, salmonberry (Rubus spectabilis), and invasive English ivy (Hedera helix). Broadleaf weeds (nettles), English ivy, and grasses occur as well in some areas. Recommendations The goal of these prescriptions is to create a low growing plant community of small trees, shrubs and forbs that will occupy the site and require minimal work in the future. This means less site disturbance, less potential for exposing mineral soils to erosion, and less disturbance of wildlife habitat over time, while protecting views. Contractors are limited to the use of chainsaws and other hand tools due to the slope steepness in the subject area. Zone 1- Prescription The view protection work can be accomplished in Zone 1 using a combination of 3 treatments: 1. Cut - to stump height of 6 inches and allow to resprout (called coppicing) 2. Cut and treat with an approved herbicide to prevent resprouting 3. Crown reduce - lowering the height of the trees crown using cuts to lateral branches. Washington Forestry Consultants, Inc. Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan Bigleaf maple is the dominant species in Zone 1. Resprouts from cutting only, can grow back quickly, often exceeding 6-8 ft. of growth in year 1, slowing to 2-3 ft. per year thereafter. Because the site is heavily stocked with grasses, shrubs and other trees, it is recommended that the bigleaf maple be controlled using the cut and treat prescription. The following is a specific summary by species for the prescribed work in Zone 1: 1. Cut all bigleaf maple sprout clumps as low as possible and treat the remaining stumps/canes with a 25% solution of Garlon 4 Ultra mixed with mineral oil. The guidelines for application are attached. This will control regrowth from the stumps. 2. Cut all cherry and Scouler willow and treat with Garlon 4 Ultra similar to the bigleaf maple. 3. Cut all conifer seedlings below the first live branch. 4. Cut the western hazelnut, oceanspray, and serviceberry 6-12 inches above the groundline and allow to resprout. Do not treat with Garlon 4 Ultra. These plants will resprout vigorously and restock the site. Their root systems will continue to provide soil stability. 5. Treat the patches of Himalayan blackberry with a low volume foliar application of Garlon 4 Ultra (5%) mixed with 2 ounces/acre rate of Escort. This will provide good control of the blackberry, though there will be some resprouting next year that will require retreatment. Three weeks after treatment, cut the blackberry using chainsaws - dice it up into short pieces so it lies flat to the ground. The cut up canes can be used as mulch for new plantings. 6. In the late -winter or sprung (Feb. 151h to March 151h) of the following year, plant into the gaps where no trees or shrubs occur (primarily the blackberry areas) with red -twig (Cornus sericea) and yellow -twig dogwood (Corpus sericea Tlaviramea). These trees have a mature height of 15 ft., and can be top pruned to create more of a shrub form. They are available as 2-0 bare -root stock and the 18- 24 inch tall seedlings are recommended. These trees should be planted on 5 ft. centers within the gaps, and at least 5 ft. away from other desirable trees or shrubs. Mulch each seedling with an 18 inch diameter ring of bark mulch that is 2-3 inches deep. Planting in late winter or early spring and mulching, will eliminate the need for watering in the summer. The required number of trees will need to be determined after the blackberry is controlled and other tree work is done. 7. If the mountain beaver population begins to forage on the newly planted tree seedlings, then it is recommended that the population be reduced by trapping.

Slash Disposal. -- The branches (4 inches and smaller) from the pruning and removal in Zone 1 are to be piled in small brush piles no larger than 8 ft. wide and 6 feet tall. The piles should be created in spots with undesirable (blackberry) or no desirable shrubs. These brush piles will create areas for small mammal protection and shelter. The larger stem wood is to be lopped into 3 ft. lengths and scattered to add value to the soils. With more light reaching the forest floor, the understory plants will flourish providing more forage and cover for wildlife. This new growth coupled with the new plantings of red -twig and yellow -twig dogwood will provide lush, green buffers of live vegetation between piles. This slash disposal plan is in accordance with recommendations made in the 2006 Urban Wildland Interface Code Sections 603 and 604 and Table 603.2 in the appendices. Zone 2 - Prescription The trees in Zone 2 are contiguous and range from 30 to over 80 feet tall. Pruning will need to be done on many of the trees. Selective removal is prescribed where stand density is high. In all cases, the site is to remain fully stocked with root systems intact for slope stability. The following is the prescription for Zone 2: 1. Cut the Scouler willow 6 inches above the groundline - but do not treat. There are only a small number of these trees, located at the topographic break south of Washington Forestry Consultants, Inc. 7 Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan the staircase. The trees will resprout and the root system will continue to provide slope stability. 2. Bigleaf maple and red alder that was previously topped 2-10 ft. above the groundline or is multi -stemmed with 4 or more stems - cut at 6 inches above the groundline - Do not Treat. 3. All other bigleaf maple, red alder, and Douglas -fir - crown reduce to a height of 30 ft. 4. Selectively remove the following trees by cutting to a stump height of 6 inches: # Species DBH (in) Work Final Tree Height ft 22 Alder 10 Cut 0.5 23 Alder 10 Cut 0.5 26 Alder 10 Cut 0.5 30 Alder 8 Cut 0.5 66 Douglas -fir 6 Crown reduce 6 91 Willow 16 Cut 0.5 197 Alder 12 Cut 0.5 198 Dou las-fir 20 Cut 0.5 200 Bigleaf maple 6 Cut and treat 0.5 236 Willow 8 Cut and treat 0.5 237 Willow 12 Cut and treat 0.5 239 Willow 12 Cut and treat 0.5 [:240 Bigleaf maple 9 Cut 0.5 *Tree numbers and species from Synthos, LLC for #22 through 91 in this inventory. There are nine conifers north of the building. They are in the vicinity of tree #'s 199 and 200. These include Douglas -firs, western hemlock and Port Orford Cedar ranging in diameter from 10 to 28 inches DBH. The required work is to raise the crowns on all of these 9 trees an additional 15 ft. from the existing height of branches. Photo D. Conifers in right of photo to have crowns raised an additional 15 feet. Washington Forestry Consultants, Inc. 8 Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan Slash Disposal. -- The slash disposal prescription is the same as for Zone 1, with the exception of trees numbered 198 through 240 in the above table and the 9 conifers that have their crowns raised. The branches of these trees should be chipped and removed from the site and the wood removed to at least 25 ft. behind top of bank. Hazard Trees. -- Trees that may be hazardous to the staircase and its users will be mitigated by the crown reduction pruning applied across Zone 2. Zone 3 - Prescription All of the Zone 3 trees are below the plane of view from the buildings and top of bank. This zone includes actively eroding slope areas. No work is prescribed for Zone 3 other than mitigation of hazard trees. If any trees are determined to be hazardous to the staircase, then they should be crown reduced to minimize the risk to the targets. The root systems of the trees in this zone will be maintained and the risk of destabilization of the slope is reduced.

The work will provide protection of the views for the project owner, protect surface soils and slope stability, improve wildlife and habitat protection, and will, over time, reduce the necessary impacts to the slope and it's vegetation to protect views. No `arboriculturally improper' tree topping would be done. All work is required to conform to the ANSI A300 standards for proper pruning. This includes the initial tree management activity and all subsequent tree management activity in future years. By selectively removing and controlling resprouting of some tree species such as bigleaf maple, coupled with planting small scale trees in the gaps and protecting desirable shrubs, a more stable low -growing plant community will be developed in Zone 1. Future entries will need to be made in Zone 2 since the slopes prevent significant tree removal. Trees that are crown reduced will require repeated treatments about every 5 years into the future to protect views. Also, invasive plant species (blackberry and English ivy) will be reduced as the new trees/shrubs colonize the open areas at the top of the slope. All tree pruning is to be completed by or under the supervision of an International Society of Arboriculture Certified Arboristo. Washington Forestry Consultants, Inc. 10 Olympia, WA Arcbbishol2 Brunett Retreat Center— Vegetation Management Plan Once the above prescribed work is complete, WFCI should inspect the created views and prescribe selective, but minimal additional work if necessary.

Washington Forestry Consultants, Inc. 19 Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan APPENDIX IV Glossary of Forestry and Arboricultural Terminology DBH: Diameter at Breast Height (measured 4.5 ft. above the ground line on the high side of the tree). Live Crown Ratio: Ratio of live foliage on the stem of the tree. Example: A 100' tall tree with 40 feet of live crown would have a 40% live crown ratio. Conifers with less than 30% live crown ratio are generally not considered to be long-term trees in forestry. Coppice: Cutting a deciduous tree 6 inches above the groundline with the goal of creating resprouts that can be cultured into new trees. Commonly done with oaks, Pacific madrone and other resprouting tree species. Works well for many deciduous shrub species. Crown: Portion of a trees stem covered by live foliage. Crown Position: Position of the crown with respect to other trees in the stand. Dominant Crown Position: Receives light from above and from the sides. Codominant Crown Position: Receives light from above and some from the sides. Intermediate Crown Position: Receives little light from above and none from the sides. Trees tend to be slender with poor live crown ratios. Suppressed Crown Position: Receives no light from above and none from the sides. Trees tend to be slender with poor live crown ratios. Crown Raising: Pruning the lower branches on a tree for ground clearances, tree health, and views. Crown Reduction: Pruning to proper lateral branches to reduce the size of a tree. Removal: Remove the tree by cutting at the base. Sidetrimming: Pruning branches from one or more sides of a tree to create a `window' or view corridor. Topping: Removal of the top of a tree with indiscriminant placement of cuts. Promotes sprouting and decay in the stubs and shortens the life of a tree. Washington Forestry Consultants, Inc. 20 Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan APPENDIX IV Herbicide Treatment Guidelines Cut Stump Treatment for maples, willow, chegy, and alder Cut stump treatments are done with oil soluble products that have an oil carrier. They differ from Cut Surface treatments in that the cambial region, the bark on the sides of the deciduous stumps and exposed roots are treated. ACTIVE PRODUCT INGREDIENT RATE COMMENTS Garlon 4'' Ultra Triclopyr (ester) 25% Garlon 4 Ultra Apply to cambial layer, w/ Oil with Mineral Oil bark, and exposed roots. * All product mixes should include an oil soluble blue dye. Pathfinder II and Garlon 4 Ultra with mineral oil can be applied anytime after cutting and must be applied to the bark on the sides of the stump, as well as exposed roots. It is very important to achieve 100% coverage of all bark and exposed roots. If rainfall, wet stumps, or snow prevent treatment, note the area on circuit maps and return when weather conditions allow treatment of stump(s). When treating cut stumps, treat the cambial region just inside the bark, treat any ingrown bark, treat exposed bark, and any exposed roots. The treatment is like spray painting with no runoff of product. It is very important that no bark, cambial region, or exposed roots are skipped. Dormant buds in untreated areas may break and form new trees. Stumps should be cut as low as possible to reduce the amount of product necessary to treat the stump. Treat ingrown barker / Treat cambial layer (ring) Treat all exposed bark j1'real exposed roots Always read and follow the herbicide label. Washington Forestry Consultants, Inc. 21 Olympia, WA Archbishop Brunett Retreat Center — Vegetation Management Plan Low Volume Foliar - Backpack for BlackbeEEy and English Iv Low volume backpack treatments are made during the growing season from full leaf in early May to leaf coloration. Better control will be achieved early than late season. Resprouting stumps and seedlings should be treated before they get over 6-7 feet tall. All foliage of the tree should be targeted for coverage with the spray solution to achieve the best control. A light coverage is all that is required. This target tree size will occur 2- 3 growing seasons after cycle maintenance. The same backpack configuration as described for low volume basal can be used. The adjustable cone tip can be used to achieve the desired pattern for small versus larger trees. The precautions are the same as for low volume basal - all streams, lakes, and ponds have a required 10 ft. buffer along with any other labeled precautions for the individual products. FORMULATION TARGET SEASON OF COMMENTS" APPLICATION Crossbow (5 % solution) + Blackberry Keep off of Escort XP (2 oz./acre rate) and English Full -leaf - in growing desirable + season vegetation R-11 0.5%) IVY Be sure to read and follow label directions.

Note: Even healthy trees can fail under normal or storm conditions. The only way to eliminate all risk is to remove all trees within reach of all targets. Annual monitoring by an ISA Certified Arborist or Certified Forester will reduce the potential of tree failures. It is impossible to predict with certainty that a tree will stand or fail, or the timing of the failure. It is considered an `Act of God' when a tree fails, unless it is directly felled or pushed over by man's actions. Washington Forestry Consultants, Inc. Olympia, WA 23 �z�— io4q-Sq -oo'Af� } RECEIVED BY COMMUN.. , DEVELOPMENT DEPARTMENT OCT 15 2012 10-10-12 Planning Specialist: Janet Shull City of Federal Way Department of Community Development Services Janet, thank you for taking the time with me two weeks ago. This letter is in reference to the conversation about maintaining our view over Puget Sound that is a vital aspect to the environment of our facility. In the past we have been more active in keeping the brush down to maintain the view of what we call the upper slope which is much gentler than the lower slope. The upper slope consists of many varieties of growth. Some Douglas fir that have been managed by topping. The same with Two Madrona trees. All of the deciduous trees have been kept at knee height and we love salal. Black Berries not so much. On the lower slope there are a couple maple and alder trees that are in bad shape and are a danger to the slope. I am planning to get the work this fall. The tree cutting on the lower slope likely will be phased to differ some of the expense. What exactly can we cut without making conflict? Sam Keller ?
