Our participation on this project has included the completion of a subsurface exploration and geotechnical design report, dated January 27, 2005, and the design of this reinforced rockery. We understand that a rockery is proposed along the south sides of Lots 9, 10, and 11, and will face primarily structural fill to raise site grades on this project. The maximum rockery height is planned to be about 6 feeL appropriate equipment such that a minimum compaction level of 95 percent of the modified Proctor maximum dry density (American Society for Testing and Materials [ASTMJ:D 1557) is achieved. Once the reinforced fill is constructed, it is typically shaped at the face, and the rockery facing is constructed conventionally. For this project, we have designed the rockery for a maximum height of 6 feet. We have assumed that the on-site soil will be used. Based on these criteria, we have calculated a minimum vertical spacing of 2 feet, a minimum top embedment length of 3 feet, and a minimum embedrnent length of 6 feet behind tl1e face of the fill embankment for each geogrid-reinforcement layer. We recommend the use of a geogrid that has a minimum allowable long-term design strength of 2,000 pounds per foot. All rockery sections with heights between 3 and 6 feet should include the above- recommended geogrid reinforcements. Rockeries less than 3 feet in height do not require reinforcement We recommend that we be aJlowed to observe construction of the reinforced rockery to confirm that our design recommendations are adequately interpreted and incorporated into the project. We would also perform a number of density readings as work proceeds to verify that the recommended minimum compaction levels have been achieved. We appreciate the opportunity to be of service on this project. Please do not hesitate to call ifwe can be of further assistance, or if you have any questions regarding this letter.

TH£ FOLLOWING ITEMS SHALL HA VE INSPECTlON: MONITOR AND APPROVE 71-1£ PLACEMENT OF ALL STRUCTURAL FILL INCLUDING 71-1£ POND BERMS, AND STRUCTURAL FILL ADJACENT TO TH£ ROCKER/ES. .:;; In general, all aspects of the planned rockery wall should be constructed in accordance with applicable guidelines for such features as face batter angle, toe ernbcdment, rock size, placement, and drainage features. Examples of acceptable rockery construction guidelines are the Associated Rockery Contractors' Standard Rockery Construction Guidelines, King County Building and Land Development's Rockery Standards, or other applicable local guidelines. VERIFY TH£ SUITABILITY OF BEARING :" SOILS AFTER £XCAVAT10N AND PRIOR TO PLACEMENT OF STRUCTURAL FILL, RETAINING WALLS IF ANY, ROCKER/ES, ROADS AND FOOTlNGS. Reinforced rockeries are designed to perform as a stable reinforced fill, protected from erosion by a rockery facing. As such, performance of the finished system is dependent on adequate construction of both the reinforced fill and the facing. Sheet I of 1, attached to this letter, provides a graphical representation of the reinforced rockery construction, as described. Geogrid reinforcing should be placed at the specified elevations shown on the referenced plan sheet, and should be laid flat. The geogrid-reinforcing material should be free of wrinkles and folds. The joints between the separate geogrid-reinforcing material should be completed in accordance with the manufacturer's recollllllended procedures, which vary depending on the specific product selected. Adequate length should also be taken into consideration for the wrap around face height and top embedment length of the geogrid-reinforcing layer. Suitable fill material should be placed in loose lifts not exceeding 8 inches in thickness and should be uniformly compacted with the !MlanJOffire• 911 BliliA=u,,Su;re 100 • Kiddand, WA 98033 •PI (425) 827-7701 •FI (425)827-5424 ~ttOffice• 2911112 HewiaAvenue,Suite2 • Everett, WA 98201 • l' j (425) 259-0522 • F j (425)252-3408 www.acsgeo.com :, .•.

Tract's A within this plat contain trees that must be retained per said approved Tree Retention Plan. Any proposed clearing, grading or construction activiUes that will (or may) impact a significant tree within said lots must be reviewed and approved by Klng County ODES Land Use Services Divislon and/or successor, for compliance with said Tree Retention Plan. The current landowner and future landowners shall maintain and protect said trees and secure permits as required to perform any maintenance and/or related activity such as hazard tree remediation. • The pennit applicant shall determine that the final tree retention plan does not include significant trees unable to survive more than ten years after the date of project completion. • Significant Tree Protection: 1.Prior to any clearing all trees to be retained shall be flagged. 2. Prior to grading and throughout construction, a temporary chalnllnk, wire or plastic net fence shall be used to identify the protected area (drip line) of any significant tree designated for retention. The height of such fendng shall be adj.Jsted according to the topographic and vegetative conditions of the site to provide clear visual delineation of the protected area. The size of the protected area around the tree shall be equal to one foot diameter for each inch of tree trunk diameter measured four feet above the ground or at the drip line of the tree. • At no time dudng and after construction shall the following be permitted within the significant tree protection area: ( a) i'mpervious surfaces, fill, excavation, or storage of construction materials (b) grade level changes, except In limited circumstances where proposed improvements using permeable materials are determined by an arborist to be non-detrimental to the trees root system. •Significant Tree Maintenance: (a) All significant trees shall be maintained for the llfe of the project including monitoring. (b} Al! significant trees shall be pruned and trimmed as necessary to malntain a healthy growing condition or to prevent primary limb failure. This requirement shall not be interpreted to allow: (1) topping of primary sloms (2) pruning that results in the loss of 20 percent of vegetative mass (3) cutting of major roots, except i'n preparation for transplantation or as deemed nece$sary and/or acceptable by a certified arborist (4) mth the exception of dead, diseased or damaged trees specifically retained to provide wildlife habltat; other dead, diseased, damaged or stolen planting shall be replaced immediately or the next plantlng season ff the loss does not occur ln a planting season. • The Significant Trees to be retained as shown on the approved Slgnlflcant Tree Retention Plan shall be mai'ntained by the future owners of the proposed lots, consistent wlth KCC 16.82.156. Note: All tree's to be removed, pruned, or limbed from public right of wa)S requires a right of way use permit from the appropriate public agency and needs to be secured and submltted to KC ODES prior to any clearing ln these areas.

Any unsatisfactory conditions shall be corrected prior to start of work. ahen conditions detrimental to plant growth are encountered, such as rubble fill, adverse drainage conditions, significant vegetation, or obstructions, the landscape con tractor /developer shall notify KC DOES prior to planting. Beginning of work constitutes acceptance of conditions as satisfactory. • Plants installed in undisturbed areas shall be integrated with existing native vegetation, and planted in a random, naturalistic pattern. LQCA TE/STAKE/VERIFY PLANTING AR(AS • Landscape contractor/Developer shall field locate, stake, and verify planti'ng areas and configurations prior to planting. This shall approximate what is shown on the ODES approved Signmcant Tree Retention plan. All revisions/changes shall be pre-approved by DOES and documented for recording at final plat approval. APPROVE PLANTING LQCA 770NS AND SPACING • Planting locations shown on planting plans are approximate, based on anticipated site conditions. Actual planting locations may vary from those shown due to final site conditions and locations of existing vegetation. Nevertheless, any variations from the planting plan will require prior approval by KC DOES. • Significant tree spacing shall be a minimum of fifteen feet (15' for non-street trees or 40' on center for street trees) or as stated on the approved planting plan. Spacing shall be adequate to allow significant tree's room to expand through the future years. PART 2 PLANT MATERIAL STANDARDS • Landscape contractor/developer shall examine plant material prior to planting. Any material not meeting the required specifications shall be immediately removed from the site and replaced with like material that meets the required standards. Plant material shall meet the requirements of County, State and Federal laws with respect to plant disease and infestations.

These certificates shall be made available to KC DDES as requested by the inspector. • Plant materfals shall be locally grown (Western WA, Western OR, or Western BC), healthy, bushy, in vigorous growing condition, and be guaranteed true to size, name and variety. If replacement of plant material ls necessary due to construction damage or plant failure within three (3) years of installation, the sizes, species and quantities shall be equal to specified plants as indicated on the approved plans. • Plants shall be nursery grown, well-rooted of normal growth and habit, and free from disease or infestation. KC ODES reserves the right to require replacement or substitution of any plants deemed unsuitable. • Trees shall have uniform branching, single straight trunks and the central leader intact and undamaged. Balled and burfapped stock shall have been root-pruned at least once within the previous two years, and the plant stock shall have been grown In a container for at least one full growing season. Container stock shall be fully rooted but not root-bound. Plant matedal with damaged root zones or broken root balls will not be accepted. • Coniferous trees shall be nursery grown, full and bushy, and with uniform branching and a natural non-sheared form. Original central leader must be healthy and undamaged. •Landscape contractor/developer shall submit a list of plant supplier names, addresses, phone numbers and storage/growing location of the material to KC DDES prior to planting. SUBSTIWT/Qt/$ • Substitution!/ of specified plant species, size or condition will be allowed only with prior written appraval from KC DOES. PART 3 PLANT INSTALLATION SOIL PREPARATION/AMENDMENTS • Prior to instalfatlon of plantings, all construction debris and any other non-native material shall be removed from the mitigation area. Trees and shrubs shall be pit planted as shown in the approved plan deta,1s. A soil moisture retention agent (polymer) shall be lncluded In planting backfill per manufacturer's specification. • In non-graded planting areas, planting pits shall be backfilled with a 50/50 mixture of imported, weed free topsoil and the native soil from the plan ting pit. In graded areas, plantings shall be Installed directly into newly placed topsoil. Imported topsoil shall be a 3-way mix acquired from an approved local supplier. • Soi/Moist, or equivalent, shall be added to the topsoil backfill of all planting pits. The 5011Moist shall be hydrated before being added to topsoil backfill. Manufacturers recommended application rates and usage shall be followed. • Woody plantings shall be fertillzed with a slow release (8 month} high nitrogen, low phosphorus granular fertilizer (21-3-7), with application rates as specified by the manufacturer. Fertilizer shall be applied after planting pit is backfilled, and prior to application of mulch. Fertilizer shall not be applied between November and March. • Outside of wetland areas, a 3 inch layer of mulch (medium Doug Fir bark} shall be placed around the base of each new tree to a 36" diameter for erosion, weed con trot and moisture retention. • Existing natural or landscaped areas that are damaged during construction shall be restored to their original condition, unless improvements or modifications are specified for those areas. •Landscape contractor/developer shall exercise care to protect from injury to trunk, roots, or branches of any trees or shrubs that are to remain. Any living woody plant that is damaged during construction shall be treated within 24 hours of occurrence. Contractor shall prune wounded portions of plant immediately after damage occurs. Injured plants shall be thoroughly watered and additional measures shall be taken (as appropriate} to aid in plant survivability. Grading: The duff layer and native topsoil shall be retained In an undisturbed state to the maximum extend practfcable.

The material shall be reapplied to other portions of the site where feasible. Areas that have been cleared and graded shall hove the soil moisture holdi'ng capacity restored to that of the original undisturbed soil native to the site to the maximum extent practicable. The so11 in any area that has been compacted or that has had some or all of the duff layer or underlying topso11 removed shall be amended to mitigate for lost moisture-holding capacity. The amendment shall take place between May 1 and October 1. Replaced topsoil shall be a minimum of 8 Inches thick, unless the applicant demonstrates that a different thickness will provide conditions equivalent to the soil moisture holding capacity native to the site. Replaced topsol/ shall have an organic matter content of between 8 to 13 percent dry weight and a pH suitable for the proposed landscape plants. CLEAN UP • Landscape contractor/developer shall be responsible for the removal of construction material and debris on the site following installation of plant materials.

Plants replaced shall be re/nitiated under plant guarantee conditions. The monitoring period shall be three (J) years from installation acceptance in writing by the ODES lnspector. PART 5 -FINAL ACCEPTANCE • Upon completion of plant,'ng, the landscape contractor/developer shall provide the DDES Inspector with a set of clearly marked prints designating the actual locations of plantings within the mitigation area. Landscape contractor/developer shall keep a complete set of prints at the job site during construction for the purpose of 'red lining' changes or modifications to the approved plans and shall update said information on a daily basis. • KC DDES shall approve planting locations as depicted on the approved replanting plan. If items are to be corrected a punch list shall be prepared by the ODES Inspector and submitted to the Landscape contractor/developer for completion. After punch list Items have been completed, ODES Inspector shall review the project for final acceptance of plan implementation. • AS BUILT SUBMITTAL ON PLATS Note: If revisions and/or changes have been tree retention plan submit an As-Built plan. As-Built Plan is not required. made to the initial ODES approved significant If no changes/revisions have been made an Prior to final plat inspection for the Significant Tree Retention Plan permittee shall submit an AS-BUILT Significant Tree Retention Plan to the ODES Inspector showing all plan revisions/changes and verifying that the DDES approved Significant Tree Retention plan (approved at the DDES Engineering Review stage) has been completed per plan requirements. This AS-BUILT plan shall be reviewed and approved by the Site Development Specialist/Forester that it conforms to 50-220 and can be recorded. If approved the plan wi1/ be ser/t back to the DOES Inspector for final plat inspection processing. Mitigation monltorin<j for Significant Tree shall commence upon acceptance and approval of this AS-BUil r plan and last for 3 years or growing seasons.

MARTIN PROPERTY Significant Tree Retention Notes & Details Project Number: LOSPOO 19 Parcel Number: I 023059383 PART 6 MAINTENANCE ANO CONTIGENCY Note: If street tree's to be planted also qualify for significant tree's then the street tree maintenance and monitoring process shall be used. • Mai'ntenance will be performed twice per year to address any conditions that could jeopard1'ze the success of the mitigation area. Established performance standards for the project will be compared to the moniton'ng results to judge the success of the mitigation project. If there is a significant problem with achieving the performance standards, the bond holder shall work w;th KC DDES to develop a contingency plan. Contingency plans can include, but are not limited to: regrading, additional plant installation, erosion control, mediations to hydrology, and plant substitutions of type, size, quantity and location. Such contingency plan shall be submitted to the KC DDES Inspector by December 31 of any year when deficiencies are discovered. Contingency will include many of the items listed below and would be implemented if these performance standards are not met. Maintenance and remedial action on the site wJ11 be implemented immediately upon completion of the monitoring event (unless otherwise specifically indicated below). • During year one, two and three replace all dead plant material. • Water all plantings at a rate of 1" of water at least every week between June 15 - September 15 during the first year after installation, and for the first year after any replacement plontlngs (C & M). • Replace dead plants with the same species or a substitute species that meets the goal and objectives of the enhancement plan, subject to KC DDES approval. • Re-plant area after reason for failure has been identified (e.g., moisture regime, poor plant stock, disease, shade/sun conditions, wildlife damage, etc}. • Remove/control weedy or exotic invasive plants (e.g., Scot's broom, reed canary grass, Himalayan blackberry, purple Joosestrife, etc.) by manual or chemical means as approved by KC DOES. Use of herbicides or pesticides within the mitigation area would only be implemented if other measures fa11ed or were considered unlikely to be successful, and would require prior KC DDES approval. Trees and shrubs should be weeded to the dripline and mulched to a depth of J inches. All non-native vegetation must be removed and dumped off site at an approved location. • Clean-up trash and other debris. • Selectively prune woody plants to thin and remove dead or diseased portion of trees. PART Z PERFORMANCE BOND • To assure the success of the mitigation, a performance bond will be posted with KC ODES by the Developer at the time of plat approval for the cost of implementing the mitigation plan to be monitored for three (J) years. It will be the Developer / permittee responsibility to request a final Inspection at the end of the three (J) year monitoring period and to release the posted bond. The bond quantity ca/cu/at/on form for both existing significant trees and trees to be planted shall be completed and submitted to ODES Site Development Services prior to approvr;I of the Significant Tree Retention Plan (the bond form will be provided by the SDS Forester at the time of the Significant Tree Retention plan review stage). The actual bond w,11 need to be submitted to DDES prior to project acceptance for field inspection by the Land Use Inspection Unit. Note: The Significant Tree Retention Plan shall include depiction of tree planting details with written planting 1'nstallation notes. Street trees shall be provided as fallows (per KCRS 5.03 ond KCC 2/A.16.050): • Trees shall be planted at a rate of one tree for every 40 feet of frontage along all roads. Spacing may be modified to accommodate sight distance requirements for driveways and intersections. • Trees shall be located within the street right-of-way and planted in accordance with Drawing No. 5-009 of the 1993 King County Road standards, unless King County Department of Transportation determines that trees should not be located in the street right-of-way. • If King County determines that the required street trees should not be located within the right-of-way, they shall be located no more than 20 feet from the street right-of-way line . • The trees shall be owned and maintai'ned by the abutti'ng lot owners or the homeowners association or other workable organization unless the county has adopted a maintenance program. Ownership and mai'ntenance shall be noted on the face of the final recorded plat. • The species of trees shall be approved by DDES if located within the right-of-way, and shall not include poplar, cottonwood, soft maples, gum, any fruit bearing trees, or any other tree or shrub whose roots are likely to obstruct sanitary or storm sewers, or that is not compatible with overhead utility lines (see list of acceptable trees above). • The street tree plan shall be reviewed and approved by the ODES project review engineer in coordination with the ODES Forester if combi'ned with the Significant Tree Retention Plan. • The street trees must be installed and inspected or a performance bond posted prior to recording of the plat. If a performance bond is posted, the street trees must be installed and inspected within one year of recording of the plat. At the time of inspection, if the trees are found to be installed per the approved plan, a maintenance bond must be submitted or the performance bond replaced with a maintenance bond, and held for one year. After one year, the maintenance bond may be released after DDES has completed a second inspection and determined that the trees have been kept healthy and thriving.

Section 2.120, of the 199J Ki11g; County Road Standards, allows DDES to apprpve illuminlltion as a means of mitigating deficient sag vertical curves for night time conditions. 1n an effort to eliminate inconsistencies in illumination designs, this office met with Puget Power regarding ciiteria for illumina1lng sag vertical cutves on residential streets. We mutually agreed on a minimum light level of0.4 foot-candles and a 6: I m1iformlty ratio. To meet these criteria, design reSidential street lighting as follows; 100 watl High Pressure Sodium luminaires 25 foot mounling height 100 to 120 foot spacing, thro,1ghout lhe sag curve. as defi~ed by King County Road Standards Illumination plans. which incorporate these elemen1s, will pro"ide· night time stopping sigllt distanoe on roadway widlhs of22 to lG feel, without e:,ceessive U]umina'tion ofneighborh1g liomes.

Our participation on this project has included the completion of a subsurface exploration and geotechnical design report, dated January 27, 2005, and lhe design of this reinforced rockery. We understand that a rockery is proposed along the south sides of Lots 9, 10, and 11, and will face primarily structural fill tu raise site grades on this project. The maximum rockery height is planned to be about 6 feet. In general, all aspects of the planned rockery wall should be constructed in accordance with applicable guidelines for such features as face batter angle, toe embcdment, rock size, placement, and drainage features. Examples of acceptable rockery construction guidelines are the Associated Rockery Contractors' Standard Rockery Construction Guidelines, King County Building and Land Development's Rockery Standards, or other applicable local guidelines. Reinforced rockeries are designed to perform as a stable reinforced fill, protected from erosion by a rockery facing. As such, performance of the finished system is dependent on adequate construction of both the reinforced fill and the facing. Sheet I of 1, attached to this letter, provides a graphical representation of the reinforced rockery construction, as described. Geogrid reinforcing should be placed at the specified elevations shown on the referenced plan sheet, and should be laid flat The geogrid-reinforcing material should be free of wrinkles and folds. The joints between the separate geogrid-reinforcing material should be completed in accordance with the manufacturer's recommended procedures, which vary depending on the specific product selected. Adequate length should also be taken into consideration for the wrap around face height and top embedment length of the geogrid-reinforcing layer. Suitable fill material should be placed in loose lifts not exceeding 8 ioches in thickness and should be uniformly compacted with the KltldandOffice• 911 HfrhA,,nu,,Suite 100• Kid<l.md, WA 98033• PI (425) 827-7701 •FI (425) 827-5424 FNerettOffice• 29ll 112HewmA,enuo, Suire2• l><reu, WA 98201 • 1' I (425) 259-0522• Fl (425)252-3408 www.a.esgeo.com ! appropriate equipment such that a minimum compaction level of 95 percent of the modified Proctor maximum dry density (American Society for Testing and Materials [ASTM]:D 1557) is achieved. Once the reinforced fill is constructed, it is typically shaped at the face, and the rockery facing is constructed conventionally. For this project, we have designed the rockery for a maximum height of 6 feet. We have rssumed that the on-site soil will be used. Based on these criteria, we have calculated a mini.mm~ vertical spacing of 2 feet, a minimum top embedment length of 3 feet, and a minimum embedment length of 6 feet behind the face of the fill embankment for each geugrid-reinforcement layer. We recommend the use of a geogrid that has a minimum allowable long-term design strength bf 2,000 pounds per foot. All rockery sections with heights between 3 and 6 feet should include thb above- recommended geogrid reinforcements. Rockeries less than 3 feet in height do uotf require reinforcement. ! We recommend that we be allowed to observe construction of the reinforced rockery to 1confirm that our design recommendations are adequately interpreted and incorporated into the pro}ect. We would also perform a number of density readings as work proceeds to verify that the recoclmended minimwn compaction levels have been achieved. ; Vle appreciate the opportunity to be of service on this project.

Tract's A within this plat contain trees that must be retali1ed per said approved Tree Retention Plan. Any proposed clearing, grading or construction activities that will (or may) impact a significant tree within said lots must be reviewed and approved by Ki'ng County ODES Land Use Services Division and/or successor. for compliance with said Tree Retention Plan. The current landowner and future landowners shall maintain and protect said trees and secure permits as required to perform any maintenance and/or related activity such as hazard tree remediation. • The permit applicant shall determine that the final tree retention plan does not include significant trees unable to survive more than ten years after the date of project completfon. • Significant Tree Protection: 1.Prior to any clearing all trees to be retained shall be flagged. 2. Prior to grading and throughout construction, a temporary chain/ink, wire or plastic net fence $hall be used to identify the protected area (drip line) of any signlflcant tree designated for retention. The height of such fencing shall be adjusted according to the topogrc;phic and vegetative conditions of the site to provide clear visual delineation of the protected area. The size of the protected area around the tree shall be equal to one foot diameter for each inch of tree trunk diameter measured four feet above the ground or at the drip li'ne of the tree. •At no time duri'ng and after construction shall the following be permitted withi'n the significant tree protection area: ( a) impervious surfaces, fill, excavation, or storage of construction material.s (b) grade level changes, except in limited circumstances where proposed improvements using permeable materials are determi'ned by an arborist to be non-detrimental to the trees root system. • Significant Tree Maintenance: {a) All significant trees shall be maintained for the fife of the project including monitoring. (b) All significant trees shall be pruned and trimmed as necessary to maintain a healthy growing condition or to prevent primary limb faifure. This requirement shall not be interpr'eted to allow: (1) topping of primary stems (2) pruni'ng that results in the loss of 20 percent of vegetative mass (3) cutting of major roots, except in preparation for transplantation or as deemed necessary and/or acceptable by a certified arborist ( 4) With the exception of dead, diseased or damaged trees specifically retained to/rovide wl'ldlife habitat; other dead, diseased, damaged or stolen planting shall be replace immediately or the next plan ting season if the loss does not occur in a planting season. • The Significant Trees to be retained as shown on the approved Significant Tree Retention Plan shall be maintained by the future owners of the proposed Jots, consistent with KCC 16.82.156. Note: All tree's to be removed, pruned, or 1/mbed from public right of ways requires a right of way use permit from the appropriate pub/le agency and needs to be secured and submitted to KC DOES prior to any clearing in these areas.

MARTIN PROPERTY Significant Tree Retention Notes & Details Project Number: LOSPOO 19 Parcel Number: I 023059383 PART 6 MAINTENANCE AND CONTIGENCY Note: If street tree's to be planted also qualify for significant tree's then the street tree maintenance and monltori'ng process shall be used. • Maintenance will be performed twice per year to address any conditions that could jeopardize the success of the mitigation area. Established performance standards for the project w111 be compared to the monitoring results to judge the success of the mitigation project. If there is a significant problem with achieving the performance standards, the bond holder shall work with KC DOES to develop a contingency plan. Contingency plans can include, but are not llmited to: regrading, additional plant installation, erosion control, mediations to hydrology, and plant substitutions of l)'pe, size, quantity and location. Such contingency plan shall be submitted to the KC DOES Inspector by December 31 of any year when deficiencies are discovered. Contingency will include many of the items listed below and would be implemented if these performance standards are not met. Maintenance and remedial action on the site wl'll be implemented immediately upon completion of the monitoring event (unless otherwise specifically Indicated below}. • During year one, two and three replace all dead plant material. • Water all plantings at a rate of 1" of water at least every week between June 15 - September 15 during the first year after installation, and for the first year after any replacement plantings (C & M). • Replace dead plants with the same species or a substitute species that meets the goal and objectives of the enhancement plan, subject to KC ODES approval. • Re-plant area after reason for fa11ure has been identified (e.g., moisture regime, poor plant stock, disease, shade/sun conditions, wildlife damage, etc). • Remove/control weedy or exotic invasive plants {e.g., Scot's broom, reed canary grass, Himalayan blackberry, purple loosestrife, etc.) by manual or chemical means as approved by KC DOES. Use of herbicides or pesticides within the mitigation area would only be implemented if other measures failed or were considered unlikely to be successful, and would require prior KC DOES approval. Trees and shrubs should be weeded to the dripline and mulched to a depth of J inches. All non-native vegetation must be removed and dumped off site at on approved location. • Clean-up trash and other debris. • Selectively prune woody plants to thin and remove dead or diseased portion of trees. PART Z -PERFORMANCE BOND • To assure the success of the mitigation, a performance bond w,1/ be posted with KC DOES by the Developer at the time of plat approval for the cost of Implementing the mitigation plan to be monitored for three (3) years. It will be the Developer / permittee responsibility to request a final inspection at the end of the three (3) year monitoring period and to release the posted bond. The bond quantity calculation form for both existing significant trees and trees to be planted shall be completed and submitted to ODES Site Development Services prior to approval of the Significant Tree Retentfon Plan (the bond form will be provided by the SOS Forester at the time of the Significant Tree Retention plan review stage}. The actual bond will need to be submitted to DDES prior to project acceptance for field inspection by the Land Use Inspection Unit. Note: The Significant Tree Retention Plan shall include depiction of tree planting details with written planting installation notes. Street trees shall be provided as follows (per KCRS 5.03 and KCC 21A.16.050): • Trees shall be planted at a rote of one tree for every 40 feet of frontage along all roads. Spacing may be modified to accommodate sight distance requirements for driveways and in tersectlons. • Trees shall be located withi'n the street right-of-way and planted In accordance with Drawing No. 5-009 of the 1993 King County Road standards, unless King County Department of Transportation determines that trees should not be located in the street right-of-way. • If King County determines that the required street trees should not be located within the right-of-way, they shall be located no more than 20 feet from the street right-of-way llne. • The trees shall be owned and maintained by the abutting lot owners or the homeowners association or other workable organization unless the county hos adopted a maintenance program. Ownership and mai'ntenance shall be noted on the face of the final recorded plat. '" The species of trees shall be approved by DOES If located with1'n the right-of-way, and shall not Include poplar, cottonwood, soft maples, gum, any fruit bearing trees, or any other tree or shrub whose roots are likely to obstruct sanitary or storm sewers, or that is not compatible with overhead utility lines (see list of acceptable trees above). c The street tree plan sha/J be reviewed and approved by the ODES project review engineer in coordination with the ODES Forester if combined with the Significant Tree Retention Plan. • The street trees must be installed and inspected or a performance bond posted prior to record1'ng of the plat. If a performance bond Is posted, the street trees must be installed and inspected within one year of recording of the plat. At the time of inspection, if the trees are found to be installed per the approved plan, a maintenance bond must be submitted or the performance bond replaced with a maintenance bond, and held for one year. After one year, the maintenance bond may be released after DOES has completed a second inspection and determined that the trees have been kept healthy and thriving.

Lots Tract A within this plat contain trees that must be retai'ned per said approved Tree Retention Pion. Any proposed clearing, grading or construction activities that will (or may) lmpact a significant tree within said Jots must be reviewed and approved by King County DOES Land Use Services Division and/or successor, for compliance with said Tree Retention Plan. The current landowner and future landowners shall maintain and protect said trees and secure permits as required to perform any maintenance and/or related activity such as hazard tree remediation. • The permit applicant shall determine that the final tree retention plan does not include significant trees unable to survive more than ten years after the date of project completion. •Significant Tree Protection: 1.Prior to any clearing all trees to be retained shall be flagged. 2. Prior to grading and throughout construction, a temporary chain/ink, wlre or plastic net fence shall be used to identify the protected area (dri'p line) of any significant tree designated for retention. The height of such fenci'ng shall be adjusted according to the topographic and vegetative conditions of the site to provide clear visual delineation of the protected area. The size of the protected area around the tree shaJ/ be equal to one foot diameter for each Inch of tree trunk diameter measured four feet above the ground or at the drip line of the tree. •At no time during and after construction shall the following be permitted within the significant treei protection area: (a) i'mpervious surfaces, fill, Bxcavation, or storage of construction materials (b) grade level changes, except in limited clrcumstances where proposed improvements using permeable materials are determined by an arborist to be non-detrimental to the trees root system. •Significant Tree Maintenance: (a) All significant trees shall be mai'ntained for the life of the project including monitoring. (b) All significant trees shall be pruned and trimmed as necessary to maintain a healthy growing condition or to prevent primary limb fal'lure. Thls requirement shall not be Interpreted to allow: (1) topping of primary stems (2) pruning that results in the loss at 20 percent of vegetative mass (3) cutting of major roots, except in preparation for transplantation or as deemed necessary and/or acceptable by a certified arborist (4) With the exception of dead, diseased or damaged trees specifically retained to provide wildlife habitat; other dead, diseased, damaged or stolen planting shall be replaced i'mmediately or the next planti'ng season if the loss does not occur in a planting season. • The Significant Trees to be retained as shown on the approved Significant Tree Retention Plan shall be maintalned by the future owners of the proposed Jots, consistent with KCC 16.82.156.

Grading: The duff layer and native topsoil shall be retained in an undisturbed state to the maximum extend practicable. Any duff layer or topsoil removed during grading shall be stockpiled on-"·site in a designated, controlled area not adjacent to public resources and critical areas. The material shall be reapplied to other portions of the site where feasible. Areas that have been cleared and graded shall have the soil moisture holding capacity restored to that of the original undisturbed soil native to the site to the maximum extent practicable. The soil in any area that has been compacted or that has had some or all of the duff layer or underlying topsoil removed shall be amended to mitigate for lost moisture-holding capacity. The amendment shall take place between May 1 and October 1. Replaced topsoil shall be a minimum of 8 inches thick, unless the applicant demonstrates that a different thickness will provide conditions equivalent to the soil moisture holding capacity native to the site. Replaced topsoil shall have an organic matter content of between B to 13 percent dry weight and a pH suitable for the proposed landscape plants. CLEAN UP • Landscape contractor/developer shall be responsible for the removal of construction material and debris on the site followi'ng installation of plant materials.

PART 4 -PLANT WARRANTY AND MONITORING • Landscape contractor/developer's warranty shall /nclude replacement of plants (same size and species shown on the approved plans) that prove either to be mislocated or unsuitable as to plant material standards. Except for loss due to excessively severe climatological conditions (substantiated by 10 -year recorded weather charts), installed plant material are required to be guaranteed for three years against defects and unsatisfactory growth. Plants replaced shaft be reiriitiated under plant guarantee conditions. The monitoring period shall be three (3) years from Installation acceptance ln writing by the DDES inspector. PART 5 -FINAL ACCEPTANCE • Upon completion of planting, the landscape contractor/developer shall provide the DOES Inspector with a set of clearly marked prints designating the actual locations of plantings within the mitigation area. Landscape contractor/developer shall keep a complete set of prints at the job site during construction for the purpose of 'red lining' changes or modifications to the approved plans and shall update said information on a daily basis. • KC ODES shall approve planting locations as depicted on the approved replanting plan. If items are to be corrected a punch list shall be prepared by the ODES Inspector and submitted to the Landscape can tractor /developer for completion. After punch list Items have been completed, ODES Inspector shall review the proj'ect for flnal accspfancB of plan 1'mplemen ta tion. • AS mm T 5(/BMITTAL ON PLATS Note: If revisions and/or changes have been made to the initial DDES approved significant tree retention plan submit an As-Bu17t plan. If no changes/revisions have been made an As-Built Plan is not required. Prior to final plat inspection for the Significant Trse Retention Plan permittee shall submit an AS-BUILT Significant Tree Retention Plan to the DOES Inspector showing all plan revisions/changes and verifying that the ODES approved Sfgniflcant Tree Retention plan (approved at the ODES Engineering Review stage) has been completed per plan requirements. This AS-BUil T plan shall be reviewed and approved by the Site Development Specialist/Forester that it conforms to S0-220 and can be recorded.

MARTIN PROPERTY Significant Tree Retention Notes & Details Project Number: LOSPOO 19 Parcel Number: I 023059383 PART 6 -MAINTENANCE AND CONTIGENCY Note: If street tree's to be planted also qualify for significant tree's then the street tree maintenance and monitoring process shall be used. • Maintenance will be performed twicB per year to address any conditions that could jeopardize the success of the mitigation area. Established performance standards for the project will be compared to the monitoring results ta judge the success of the mitigation project. If there is a significant problem with achievlng the performance standards, the bond holder shall work with KC DOES to develop a contingency plan. Contingency plans can 1'nclude, but are not 1/mlted to: regrading, additional plant installation, erosion control, mediations to hydrology, and plant substitutions of type, size, quantity and location. Such contingency plan shall be submitted to the l<C ODES Inspector by December 31 of any year when deficiencies are discovered. Contingency will include many of the Items fisted below and would be implemented if these performance standards are not met, Maintenance and remedial action on the sNe will be implemented immediately upon completion of the monitoring event (unless otherwise specifically Indicated below). • During year one, two and three replace all dead plant material. • Water all plantings at a rate of 1" of water at least every week between June 15 - September 15 during the first year after installation, and for the first year after any replacement plantings (C &: M). • Replace dead plants with the same species or a substitute species that meets the goal and objectives of the enhancement plan, subject to KC ODES approval. • Re-plant area after reason for fa11ure hos been identified (e.g., moisture regime, poor plant stock, disease, shade/sun conditions, wlldllfe damage, etc). • Remove/control weedy or exotic invasive plants (e.g., Scot's broom, reed canary grass, Himalayan blackberry. purple loosestrlfe, etc.) by manual or chemical means as approved by KC ODES. Use of hBrbicides or pesticides within the mitigation area would only be implemented if other measures failed or were considered unlikely to be successful, and would require prior KC DOES approval. Trees and shrubs should be weeded to the dripfine and mulched to a depth of J inches. All non-native vegetation must be removed and dumped off slte at an approved location. • Clean-up trash and other debris. • Selectively prune woody plants to thin and remove dead or diseased portion of trees. PART 7 -PERFORMANCE BONO • To assure the success of the mitigation, a performance bond will be posted with KC ODES by the Developer at the time of plat approval for the cost of implementing the mitigation plan to be monitored for three (3) years. It will be the Developer / permittee responsibl1ity to request a final inspection at the end of the three {J) year monitoring period and to release the posted bond. The bond quantity ca/cu/atfon form for both existing significant trees and trees to be planted shall be completed and submitted to ODES Site Development Services prior to approval of the Slgnificant Tree Retentlon Plan (the bond form will be provided by the SOS Forester at the time of the Significant Tree Retention plan review stage). The actual bond will need to be submitted to DOES prior to project acceptance for field lnspection by the Land Use Inspection Unit. Note: The Significant Tree Retention Plan shall Include depiction af tree planting details with written planting installation notes. Street trees shall be provided as follows {per KCRS 5.03 and KCC 21A.16.050): • Trees shall be planted of a rate of ane tree for every 40 feet of frontage along all roads. Spacing may be modified to accommodate sight distance requirements for driveways and intersections. • Trees shall be located within the street right-of-way and planted in accordance with Orawi'ng No. 5-009 of the 1993 King County Road standards, unless King County Department of Transportation determines that trees should not be located in the street right-of-way. • If King County determines that the required street trees should not be located within the right-of-way, they shall be located no more than 20 feet from the street right-of-way line. • The trees shall be owned and maintained by the abutti'ng lot owners or the homeowners association or other workable organization unless the county has adopted a maintenance program. Ownershi'p and maintenance shall be noted on the face of the final recorded plat. • The species of trees shall be approved by DOES if located within the right-of-way, and shall not include poplar, cottonwood, soft maples, gum, any fruit bearing trees, or any other tree or shrub whose roots are likely to obstruct sanitary or storm sewers, or that is not compatible with overhead uWity lines (see list of acceptable trees above). • The street tree plan shall be reviewed and approved by the DOES project review engineer in coordination with the ODES Forester if combined with the Significant Tree Retention Plan. • The street trees must be instafled and inspected or o performance bond posted prior to recording of the plat. If a performance bond is posted, the street trees must be installed and inspected withi'n one year of recording of the plat. At the time of inspection, if the trees are found to be installed per the approved plan, a maintenance band must be submitted or the performance bond replaced with a maintenance bond, and held for one year. After one year, the maintenance bond may be released after ODES has completed a second inspection and determ1'ned that the trees have been kept healthy and thriving.
