GEOTECHNICAL ENGINEERING STUDY PROPOSED PLEASANT PATH PLAT 12204 - 148TH AVENUE SE RENTON, WASHINGTON G-2884 Prepared for Mr. Robert Johnseine Pleasant Path, LLC 9805 NE 116`h St, Suite 7499 Kirkland, WA 98034 November 6, 2012 GEO GROUP NORTHWEST, INC. 13240 NE 201h Street, Suite 10 Bellevue, Washington 98005 Phone: (425) 649-8757 Email:.wchang@&eoUoupnw.com or agaston@geogroupnw.com S MOCIlGroup Northwest, Inc. November 6, 2012 Mr. Robert Johnseine Pleasant Path, LLC 9805 NE 1161h St, Suite 7499 Kirkland, WA 98034 SUBJECT: GEOTECHNICAL ENGINEERING STUDY PROPOSED PLEASANT PATH PLAT 12204 - 148"u AVE SE RENTON, WASHINGTON Dear Mr. Johnseine: Geotechnical Engineers, Geologists & Environmental Scientists G-2884 GEO Group Northwest, Inc. has completed an investigation of subsurface soils at the above referenced site in Renton, Washington. This work was performed in accordance with our proposal to you dated October 25, 2012 and authorized on your behalf by Greg Sparhawk. GEO Group Northwest, Inc., explored subsurface soil conditions at the site by excavating four exploratory test pits on October 30, 2012 and two test pits in May of 2009. Soils encountered at the test pits consisted of loose to medium dense sandy SILT and silty SAND overlying dense to very dense and gravelly silty SAND and gravelly sandy SILT with some cobbles at depths ranging from 1.5 to 3.5 feet below ground surface (bgs). Based on the results of our study, it is our professional opinion that the site is geotechnically suitable for the proposed development. The proposed buildings can be supported on conventional spread footings bearing on the dense native site soils or on compacted structural fill placed on top of the dense native soils. The loose site soils and fills are not suitable to support foundations due to their loose and variable condition. Based on the findings from our soil investigation at the site, we anticipate that the dense soil under the building areas are present at depths of approximately 2 -feet below ground surface at most locations. Some over -excavation may be necessary at select locations but firm soil conditions are likely to be found at the anticipated foundation depths. Please refer to the text of the report for more specific recommendations regarding the site development. We appreciate this opportunity to have been of service to you on this project. We look forward to working with you as this project progresses. Should you have any questions regarding this report or need additional consultation, please feel free to call us. 13240 NE 20th Street, Suite 10 Bellevue, Washington 98005 Phone 4251649-8757 Fax 4251649-8758 November 6, 2012 Proposed Pleasant Path Plat, Renton, Washington Sincerely, GEO Group Northwest, Inc.

GEOTECHNICAL ENGINEERING STUDY PROPOSED PLEASANT PATH PLAT 12204 - 148THAVENUE SE RENTON, WASHINGTON G-2884 1.0 INTRODUCTION 1.1 Project Description The project site is located at the eastern side of 148'h Avenue SE at the subject address. This address is not currently associated with a building structure but property tax records indicate that the site has addresses of 684 and 650 Nile Ave NE with parcel numbers of 1123059092 and 1123059010, respectively. The project site consists of a 4.54 acre parcel. We have been provided with a PUD Site Plan for the proposed development by Core Design which is dated October 2012. According to the site plan the development will consist of 14 new residential lots containing 1,712 square foot buildings at each lot, as shown on Plate 2 - Site Plan. Finish floor elevations for the new buildings were not provided at the time of this study. A private access road with associated parking and a 400 square foot community center will also be constructed. An underground stormwater detention vault is proposed to be located below a portion of the parking area with an estimated depth of 11 -feet below the existing ground surface. The majority of development is limited to the western portion of the property. A soft surface trail and two boardwalks are proposed for the eastern half of the site which consists of open -space and wetland areas. The existing house and accessory buildings will be demolished. 1.2 Scope of Services The tasks we completed for this study were conducted in general accordance with the scope of work presented in our proposal dated October 25, 2012. The results of our subsurface investigation and our recommendations regarding the proposed development are summarized in the following report. GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 2 2.0 SITE CONDITIONS 2.1 Site Description We have been provided with the PUD Site Plan (Sheet 3) for the proposed development by Core Design which is dated October 2012. This plan has been modified and attached as Plate 2 - Site Plan. Based upon the site plan the site consists of a relatively flat 4.5 acre parcel occupied with one single family residence and two accessory structures. The existing buildings and development are located at the western side of the lot and the eastern side of the lot is undeveloped. 2.2 Geologic Overview According to the geologic map for the site vicinity the soils at the site are reported to be Ground Moraine Deposits (Qgt). The Ground Moraine soils typically consist of glacial till, a mixture of sand, silt and gravel, which was consolidated by overriding glacial ice. These soils can usually be divided into a surficial loose to medium dense weathered zone which overlies the dense to very dense and often gray or tan colored un -weathered soil zone. 2.3 Field Investigation GEO Group Northwest, Inc., explored subsurface soil conditions at the site by excavating and logging 6 exploratory test pits labeled TP -1 through TP -6. The test pits labeled TP -1 and TP -2 were excavated at the western portion of the site in 2009 in order to support a Pavement Design by GEO Group Northwest. Test pits TP3 through TP -6 were excavated on October 30, 2012 specifically to support the following geotechnical recommendations. The test pits were located near the proposed development areas, as shown on Plate 2 - Site Plan. The test pits were excavated to depths ranging between 3 and 6 feet below ground surface (bgs). Soil samples at varying depths were collected, classified and returned to our laboratory. The test pits were then backfilled with the excavated site soils. Backfilled soils were not compacted. GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 3 2.4 Soil Conditions Soils encountered in the test pits consisted of primarily loose to medium dense sandy SILT overlying dense to very dense gravelly sandy SILT and gravelly silty SAND with varying amounts of cobble. The underlying dense to very dense soils appear to be the glacial till soils which are noted on the geologic map. For the most part, the soils at the site appear to consist of predominately SILT size particles. At a few locations and depths we visually estimate that the predominate grain size is SAND followed closely by SILT. In either case the soils are anticipated to exhibit relatively impermeable characteristics due to both their fine-grained texture and underlying dense to very dense condition. In general, the underlying competent dense soils were encountered at depths ranging from 1.5 to 3.5 feet below ground surface. Copies of the Test Pit Logs are presented in Appendix A: Test Pit Logs. 2.5 Groundwater Conditions No groundwater seepage was encountered at the test pits. It should be noted that groundwater conditions may fluctuate seasonally, depending on rainfall, surface runoff and other factors. 3.0 Seismic Considerations Based upon our subsurface investigation at the site, it is our opinion that the project buildings may be designed using the Class C soil profile from the 2009 International Building Code, Section 1613. It is our opinion that the soils at the project site are not susceptible to liquefaction, due to the absence of groundwater within the loose soil zone. 4.0 INFILTRATION EVALUATION Based upon discussions with Mr. Rob Stevens of Core Design we understand that some of the site stormwater may be routed to stormwater systems such as rain -gardens which often rely partially upon infiltration for stormwater treatment. Consequently, we have included this discussion regarding the potential for infiltration at the site. GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 4 Based upon our subsurface investigation the soils at the site consist predominately of sandy SILT and gravelly sandy SILT. Because they are fine-grained these soils are relatively impermeable. Additionally, the underlying soil deposit is dense to very dense which further inhibits the permeability of the ground. Of course the soils will allow for some infiltration under certain conditions, however, the infiltration rate for these soils is generally low. We recommend that if infiltration is used to treat site stormwater then overflow to a stormwater system should be part of the design. Alternatively, stormwater treatment facilities such as dispersion trenches may be incorporated which will allow for dispersion at times when rainfall exceeds capability of the system to provide for infiltration. 5.0 CONCLUSIONS AND RECOMMENDATIONS 5.1 General Based upon the results of our study, it is our professional opinion that the site is geotechnically suitable for the proposed development. The proposed buildings and detention vault may be supported on conventional spread footings bearing on the dense native site soils or on compacted structural fill placed on top of the dense native site soils. The overlying loose site soils are not suitable to support foundations. We anticipate that the dense soils are located at depths ranging from 1.5 feet to 3.5 below ground surface (bgs). At most of the test pit locations the dense soils were encountered at or near standard shallow foundation depths of 1.5 to 2 feet bgs. Consequently, we anticipate that over -excavation may be required only at select locations and may be limited to the area near test pit TP -2. 5.2 Site Preparation and General Earthwork The building pad areas should be stripped and cleared of surface vegetation and forest duff soils. Silt fences should be installed around areas disturbed by construction activity to prevent sediment -laden surface runoff from being discharged off-site. Exposed soils that are subject to erosion should be compacted and covered with plastic sheeting. GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 5 5.2.1 Temporary Excavation and Slopes Under no circumstances should temporary excavation slopes be greater than the limits specified in local, state and national government safety regulations. Temporary cuts greater than four feet in height should be sloped at an inclination no steeper than 1H:1V (Horizontal: Vertical) in the Ioose site soils. Temporary cuts in the dense site soils may be excavated no steeper than 1H:2V provided that no seepage is encountered. If groundwater seepage is encountered during construction, excavation of cut slopes should be halted and the cut slopes should be re-evaluated by GEO Group Northwest, Inc. If necessary the underlying very dense soils may be capable of standing at steeper inclinations such as 1MV, however, this is dependent upon the conditions at the time of excavation. If it is necessary to form such steep excavation slopes than GEO Group Northwest, Inc., must be retained to evaluate the conditions at the excavation at the time of grading to provide an evaluation of stability. If the proposed temporary excavation slopes encroach upon adjacent properties then it may be necessary to obtain an excavation easement or plan for temporary shoring at those locations. Permanent cut and fill slopes at the site should be inclined no steeper than 2H:1 V. Surface runoff should not be allowed to flow uncontrolled over the top of slopes into the excavated area. During wet weather exposed cut slopes should be covered with plastic sheeting during construction to minimize erosion. 5.2.2 Structural Fill All fill material used to achieve design site elevations below the building areas and below non - structurally supported slabs, parking lots, sidewalks, driveways, and patios, should meet the requirements for structural fill. During wet weather conditions, material to be used as structural fill should have the following specifications: 1. Be free draining, granular material containing no more than five (5) percent fines (silt and clay -size particles passing the No. 200 mesh sieve); 2. Be free of organic material and other deleterious substances, such as construction debris and garbage; 3. Have a maximum size of three (3) inches in diameter. GEO Group Northwest, Inc. November b, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page b All fill material should be placed at or near the optimum moisture content. The optimum moisture content is the water content in soil that enables the soil to be compacted to the highest dry density for a given compaction effort. The majority of the surficial site soils will be moisture -sensitive because they consist of sandy SILT and silty SAND soils. The site soils should be suitable for use as structural fill as long as they are placed near their optimum moisture content. We anticipate that the site soils will most likely be too wet to achieve the compaction requirements unless work is performed during the dry summer months. Alternatively, an imported granular fill material may provide more uniformity and be easier to compact to the required structural fill specification. If the on-site soils are to be used as engineered structural fill, it will be necessary to segregate the topsoil and any other organic- or debris-containing soil, because such soils would be unsuitable for use as structural fill. Excavated on-site material that is stockpiled for later use as structural fill should be protected from rainfall or contamination with unsuitable materials by covering it with plastic sheeting until it is used. Structural fill should be placed in thin horizontal lifts not exceeding ten inches in loose thickness. Structural fill under building areas (including foundation and slab areas), should be compacted to at least 95 percent of the maximum dry density, as determined by ASTM Test Designation D- 1557-91 (Modified Proctor). Structural fill under driveways, parking lots and sidewalks should be compacted to at least 90 percent maximum dry density, as determined by ASTM Test Designation D-1557-91 (Modified Proctor). Fill placed within 12 -inches of finish grade should meet the 95% requirement. We recommend that GEO Group Northwest, Inc., be retained to evaluate the suitability of structural fill material and to monitor the compaction work during construction for quality assurance of the earthwork. 5.3 Spread Footing Foundations The proposed buildings can be supported on conventional spread footings bearing on the dense native site soils or on compacted structural fill placed on top of the dense native site soils. Based GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 7 on the findings from our soil investigation at the site, we anticipate that the dense soils are present between at between 1.5 and 3.5 feet below ground surface (bgs). Some over -excavation and placement of structural fill may be required at foundation locations, dependent upon the proposed finish grades and the conditions encountered at the building foundation excavations. We recommend that GEO Group Northwest, Inc., be retained to verify competent soils are present at each building foundation location, at the time of construction, prior to the foundation pour(s). Individual spread footings may be used for supporting columns and strip footings for bearing walls. Our recommended minimum design criteria for foundations bearing on the dense site soils or on compacted structural fill are as follows: - Allowable bearing pressure, including all dead and live loads Dense native soil = 2,500 psf Compacted structural fill = 2,500 psf - Minimum depth to bottom of perimeter footing below adjacent final exterior grade = 18 inches - Minimum depth to bottom of interior footings below top of floor slab = 18 inches - Minimum width of wall footings = 16 inches - Minimum lateral dimension of column footings = 24 inches - Estimated post -construction settlement = 114 inch - Estimated post -construction differential settlement; across building width = 114 inch A one-third increase in the above allowable bearing pressures can be used when considering short-term transitory wind or seismic loads. Lateral loads can also be resisted by friction between the foundation and the supporting compacted fill subgrade or by passive earth pressure acting on the buried portions of the foundations. For the latter, the foundations must be poured "neat" against the existing GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 8 undisturbed soil or be backfilled with a compacted fill meeting the requirements for structural fill. Our recommended parameters are as follows: - Passive Pressure (Lateral Resistance) 350 pcf equivalent fluid weight for compacted structural fill 350 pcf equivalent fluid weight for native dense soil. - Coefficient of Friction (Friction Factor) • 0.35 for compacted structural fill • 0.35 for native dense soil We recommend that footing drains be placed around all perimeter footings. More specific details of perimeter foundation drains are provided below in Section 5.6 - Footing Drains. 5.4 Permanent Basement and Conventional Retaining Walls At the time of report preparation finish grades for the proposed development were not shown on the site plan. We anticipate that little site grading is proposed and that the new construction will be primarily at -grade. We understand that a below -grade detention vault will be located at Tract B, as shown on the site plan, below the proposed parking area. We understand that the vault may have conventional concrete retaining walls and that the anticipated depth of the vault is approximately 11 -feet below the existing ground surface. The following design recommendations may be used for permanent basement and conventional retaining walls at the project site. Permanent basement walls restrained horizontally on top are considered unyielding and should be designed for a lateral soil pressure under the at -rest condition; while conventional reinforced concrete walls free to rotate on top should be designed for an active lateral soil pressure. Active Earth Pressure Conventional reinforced concrete walls that are designed to yield an amount equal to 0.002 times the wall height, should be designed to resist the lateral earth pressure imposed by an equivalent fluid with a unit weight of 35 pcf for level backfill. GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 9 At -Rest Earth Pressure Walls supported horizontally by floor slabs are considered unyielding and should be designed for lateral soil pressure under the at -rest condition. The lateral soil pressure design should have an equivalent fluid pressure of 60 pcf for level ground behind the walls. Passive Earth Pressure and Base Friction The available passive earth pressure that can be mobilized to resist lateral forces may be assumed to be equal to 350 pcf equivalent fluid weight in both undisturbed soils and engineered structural backfill. The base friction that can be generated between concrete and undisturbed native soils or engineered structural backfill may be based on an assumed 0.35 friction coefficient. Drainage We recommend that a vertical drain mat, Miradrain 6000 or equivalent, be used to facilitate drainage behind permanent concrete basement and conventional retaining walls. We recommend that the drainage mat be installed on the back side of the wall extending from the finish grade down to a footing drain pipe. The wall footing drain pipe should consist of a 4 -inch diameter perforated rigid PVC pipe surrounded by a bed of washed gravel and separated from site soils by filter fabric, Mirafi 140N or equivalent. The drain pipe should be tightlined to discharge to the stormwater system. Backfill behind conventional retaining walls should consist of free -draining sand or gravel soils which are compacted in lifts. Backfill in areas adjacent to basement or conventional retaining walls should be compacted with hand held equipment or a hoepack. Heavy compacting machines should not be allowed within a horizontal distance to the wall equivalent to one half the wall height, unless the walls are designed with the added surcharge. 5.5 Slab -on -Grade Concrete Floors Loose site soils should be excavated from all concrete slab subgrade areas or compacted to a firm and unyielding condition. Slab -on -grade concrete floors may be constructed on top of medium GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 10 dense to dense native site soils or on top of compacted structural fill placed on top of the competent site soils. The slab -on -grade floors should not be constructed on top of loose soils. To avoid moisture build-up on the subgrade, slab -on -grade floors should be placed on a capillary break, which is in turn placed on the prepared subgrade. The capillary break should consist of a minimum of a six (6) inch thick layer of free -draining crushed rock or gravel containing no more than five (5) percent finer than the No. 4 sieve. A vapor barrier, such as a 6 -mil plastic membrane, is recommended to be placed over the capillary break beneath the slab to reduce water vapor transmission through the slab. Two to four inches of sand may be placed over the barrier membrane for protection during construction. 5.6 Footing Drains We recommend that drains be installed around the perimeter of the foundation footings. The drains should consist of a four (4) inch minimum diameter perforated rigid drain pipe laid at or near the bottom of the footing with a gradient sufficient to generate flow, as schematically illustrated in Plate 3 - Typical Footing Dram Detail. The drain line should be bedded on, surrounded by, and covered with a free -draining rock, pea gravel, or other free -draining granular material. The drain rock and drain line should be completely surrounded by a geotextile filter fabric, Mirafi 140N or equivalent. Once the drains are installed, the excavation should be backfilled with a compacted fill material. The footing drains should be tightlined to discharge to the stormwater collection system. Under no circumstances should roof downspout drain lines be connected to the footing drainage system. All roof downspouts must be separately tightlined to discharge into the storm water collection system. We recommend that sufficient cleanouts be installed at strategic locations to allow for periodic maintenance of the footing drains and downspout tightline systems. 5.7 Pavements Based upon the site plan we understand that a new private access roadway and parking will be constructed at the western portion of the site. The adequacy of pavements is strictly related to the condition of the underlying subgrade. We recommend that all pavement subgrades be compacted by several passes of a large vibratory drum roller prior to placement of the crushed rock base. Before paving, we recommend that the subgrade be proof -rolled under the supervision of the GE4 Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page I I geotechnical engineer to verify that the subgrade is firm and unyielding at the time of paving. The proof -roll may be performed by driving a fully loaded dump truck over the subgrade areas. If Ioose or yielding soils are encountered it may be necessary to over -excavate and replace with compacted structural fill in some areas. For firm and unyielding native subgrade soils we recommend the following minimum pavement sections for driveways: Class "B" Asphalt Concrete (AC) 3 inches Crushed Rock Base (314 -inch minus) 6 inches X1 Concrete Pavement 6 inches Crushed Rock Base (3/4 -inch minus) 4 inches We understand that it may be beneficial to install a base pavement layer such as ATB (Asphalt - Treated Base) prior to completion of the project. Oftentimes this can help protect the subgrade from construction impacts and reduce cost related to subgrade repairs during wet weather periods. Consequently we have calculated that the 3 -inches of AC over 6 -inches of Crushed Rock Base noted above would be equivalent to the following total pavement thickness: Class "B" Asphalt Concrete (AC) 2 inches Asphalt Treated Base (ATB) 4 inches Crushed Rock Base (314 -inch minus) 3 inches In accordance with the Washington State Department of Transportation Construction Manual, transverse cracks will develop in concrete slabs at about 15 foot intervals along the length of slabs and a slab wider than 15 feet may crack longitudinally. To control cracking of the concrete, contraction joints should be installed. Contraction joints are weakened planes which collect the cracking into a controlled joint, creating a maintainable joint in the slab, and preventing random ragged cracks which spread and require expensive maintenance. We recommend that contraction and construction joints be connected with #5 dowel bars, 30 inches long, 18 inches on center. The contraction joints should be placed at maximum 14 foot intervals. GEO Group Northwest, Inc. November 6, 2012 G-2884 Proposed Pleasant Path Plat, Renton, Washington Page 12 6.0 LIMITATIONS This report has been prepared for the specific application to this site for the exclusive use of Mr. Robert Johnseine of Pleasant Path, LLC, and his authorized representatives. We recommend that this report be included in its entirety in the project contract documents for use by the contractor. Our findings and recommendations stated herein are based on field observations, our experience and judgement. The recommendations are our professional opinion derived in a manner consistent with the level of care and skill ordinarily exercised by other members of the profession currently practicing under similar conditions in this area and within the budget constraint. No warranty is expressed or implied. in the event the soil conditions are found to vary during site excavation, GEO Group Northwest, Inc. should be notified and the above recommendation should be re-evaluated. 7.0 ADDITIONAL SERVICES We recommend that GEO Group Northwest Inc. be retained to perform a general review of the final design and specifications of the proposed development to verify that the earthwork and foundation recommendations have been properly interpreted and implemented in the design and in the construction documents. We also recommend that GEO Group Northwest Inc. be retained to provide monitoring and testing services for geotechnically-related work during construction. This is to observe compliance with the design concepts, specifications or recommendations and to allow design changes in the event subsurface conditions differ from those anticipated prior to the start of construction. We anticipate the following construction monitoring inspections may be necessary: 1. Site clearing and grubbing; 2. Over -excavation and structural fill placement at building foundation locations; 3. Verification of bearing soil conditions for foundations; 4. Structural fill placement and compaction; GEO Group Northwest, Inc. November 6, 2012 Proposed Pleasant Path Plat, Renton, Washington 5. Slab -on -grade preparation; 6. Subsurface drainage installation; 7. Proof -rolling of pavement subgrade areas.

The site is bordered b} 148'F' Avenue SE to the west. sitigle family residences to the north and south, and i,vetlands to the east. The site is currentl} occupied by a single family residence and outbuildings. Clronnd cover is predominately grass and landscaping %Wh gravel vehicular access. The entire property slopes to the southwest acid sheet flows to the west property line. The eastern boundary of the site is the boundary setbacks of a treed and heavily brush covered wetland. The King County Basin map shows the runoff from the property flows into the lower Cedar River basin. Seethe Downstream Analysis in Section 3 of this Report for a description of the downstream system The proposed project includes constructing 14 single-family cottages with detached garages, associated roadway/allcy and utilities on 1.84 acres of the property. All existing structures will be removed. Access to the site will be via 148'h Avenue SE. Partial -street improvements on 148th Avenue SF, along the property's west frontage, including pavement widening and installation of eurb, gutter, and sidewalk, will be completed as part of the project. Developed drainage consists of several flow bmp regimes in an effort to minimize the detention facility. The BMP's are Rain Gardens, preserve wetland hydrology and a combination water quality/detention facility. The majority of the site will discharge into an existing ditch downstream and south of the property within the 148th Avenue SE Right -of -Way. The site is subject to the Conservation (Level Two) Flow Control and Basic Water Quality regnis'einents within the 2005 King County Surface Water Design Manual (2005 KCS)AhUM). f��� 7-11 BE 11Tf ST L car SITE z _ - --- 1 Ur NE 4T'N .ST - z - BE 11281+ ST LU r_ — z BE 136TH ST PT -7- - _ Iy — SE 144TH ST[ 1 VICINITY MAP NOT TO SCALE Figure 1.

Stevens, P.E. 14711 NE 29th Place, Suite 101 Bellevue WA 98007 RE: Road Variance L07VO022 -- Johnseine Short Plat Dear Mr. Stevens; Thank you for your application for a variance from the 1993 King County Road Standards (KCRS). You requested a variance from Section 2.10 of the KCRS concerning the intersection spacing for the proposed access onto 148th Avenue SE. This road is classified as a collector arterial, and the KCRS requires a minimum of 300 feet of intersection spacing. The proposed location of the site access is 169 feet north of SE 123rd Street and is supported by the Department of Development and Environmental Services. The access accommodates future development to the west. Moving the access to the north property line is not viable because a 15 - foot landscaping tract owned by a homeowner's association obstructs a potential half -street. I approve a variance for reduced intersection spacing for the access road as proposed at 169 feet north of SE 123rd Street. This decision applies only to KCRS identified in the variance request. All other design requirements in the KCRS and other regulations, such as surface water management and zoning, must still be satisfied for a land use permit application, The applicant retains the rights and privileges afforded by King County Code and adopted Public Rules pertaining to road valiance processing (KCC. 14.42, PUT 10-2). This variance decision is valid for one year from date of letter unless an associated land use permit is pending or submitted within the one year period. In these cases, the variance decision is valid for the duration of the permit processing. Rob,,n H.

According to Mr, Walton the nursery has been clearing land that could be considered a wetland. I walked the back property line of Mr. Walton`s property and discovered that he also has dons some work In the wetland to install a fence, Mr. Walton cleared In the wetland and disturbed a small stream. I told Mr, Walton that he needs to talk to DDES Grading section about a permit to do this work and to atop work In the wetland. I tried to access the property of the nursery to the south but was unsuccessful because they were closed. The nursery appears to have encroached the weUand with its clearing.

Where outwash soils are saturated or underlain at shallow depth (<5 feet) by glacial till, they should be treated as till soils. 2. These are bedrock soils, but calibration of HSPF by King County DNRP shows bedrock soils to have similar hydrologic response to till soils. 3. These are alluvial soils, some of which are underlain by glacial till or have a seasonally high water table. In the absence of detailed study, these soils should be treated as till soils. 4. Buckley soils are Formed on the low -permeability Osceola mudflow. Hydrologic response is assumed to be similar to that of till soils. 2005 Surface Water Design Manual 112•l:'00 3-25 1-I L'11'i y;J1 s -+,,l{ ai\UL.ltdllE h;ElIIVIJ I-1FAi,lLi.:1�.

STF ENS, P.E. 9805 NE 116TH STRFFT, SU17F 7499 ENGINEERING PLANNING SLlRYErlNG rRweZr MnNaeFrs K/RKLAND, WASHINGTON 94034 DEVELOPED CONDITIONS The proposed project includes constructing 14 single-family cottages with detached garages, associated roadway/alley and utilities on 1.84 acres of the property. All existing structures will be removed. Access to the site will be via 148th Avenue SE. Half -street improvements on 148th Avenue SE along the property's west frontage, including pavement widening and installation of curb, gutter, and sidewalk, will be completed as part of the project. FLOW CONTROL BMP REQUIREMENTS Per Section 1.2.3.3 in the 2005 KCSWDM, projects subject to Core Requirement 43 must apply now control BMPs to impervious surfaces as directed by this section to either supplement the flow mitigation provided by required flow control facilities or provide flow mitigation where flow control facilities are not required. Flow control BMPs must be selected and applied according to the basic requirements, procedures, and provisions detailed in Section 5.2 and the design specifications for each BMP in Appendix C, Section C.2. The implementation of flow control BMPs during site development is optional and can be deferred until a permit is obtained for construction on each lot. By implementing the flow control BMPs during the development of the project, all or some of the flow control BMPs can be moved outside of the individual lots themselves and placed in designated tracts within the development. Implementation during the development process not only allows for more options in placement of flow control BMPs, but also lets the development take credit for these flow control BMPs when sizing the onsite detention/water quality system. Per the Small Lot Requirements, lots less than 11,000 square feet, each lot must connect to the local drainage system with a perforated pipe connection, and must apply flow control BMPs to mitigate runoff from an impervious area equal to 1.0% of the lot area. These BMPs can either be applied individually on each lot or if done during development, the flow control BMPs can be distributed throughout the site. For the subject project, flow control BMPs will be applied during the development of the site. Each lot will connect to the onsite detention/water quality facility through a perforated pipe connection. A portion of the 10% of mitigation for Lots 1-4, 9-12, 14 and Tract B) will be provided through the use of Rain Gardens. The area needed to be mitigated for is broken down in the table below.

The amount of impervious surface area was determined using the example sizing calculation shown in Section C.2.5.2 of the 2005 KCSWDM, where V(cf)—Surl'ace Area(sf) X 0.25(ft). The surface area can be found by rearranging the equation, SA(sf) = V(cf)/0.25(ft). The roof area is 1,647 sf each lot. A portion of the impervious road (3,303sf) and all roof area from Garage #1(759sf) will be directed to the Tract B Rain Garden. The proposed mitigated area is broken down in the table below.

See attached KCRTS printouts, Per the KCRTS printout, the vault surface area is 3,875 square feet. The outfall from the vault (rdout.rdf) meets all of the requirements Conservation Flow Control standards. The primary overflow for the vault is the riser pipe on the control structure. The water surface elevation above the riser for the 100 year, 15 -minute developed flow is calculated assuming all orifices are plugged. '1-o pass the 100 -year, 15 -minute return period storm, 0.66 cfs, through a 12" overflow riser will require 0.17 feet of head per the following equation: Q = 9.739DH312 or 0.66 9.739(1.0)H312. See attached flow frequency analysis on the following pages for calculation of the 100 -year, 15 -minute return period storm.

Topographical data and aerial photos Nvere used to delineate the upstream tributary basin, The 7.56 acre basin consists of one single family residence with outbuildings and landscaping along 148'x' Avenue SE, and pasture and forest behind the residence to the east. Table 3.2.2.1) was used to calculate the impervious area outside of the right of Aay. The impervious area was conservatively calculated at 15% since the actually density of the basin is below one dwelling unit per acre. For the 7.56 acres tributary to the site, this would be 1.13 acres of impervious surfaces. In addition to the l .13 acres of impervious surfaces in the tributary lots, the 0.07 acres of inipervious1481h Ave SE right of way must also be included. The remaining site was delineated from the aerial photographs and is broken out below. For clarification, see the upstream exhibit on the following pages.

Re: Johnseine Property SWC Job# A6-209 October 10, 2006 Page 3 of 8 2.0 METHODOLOGY On July 20, July 28, and August 3, 2006, and again on August 7, 2006, Sewall Wetland Consulting Inc. inspected the site for jurisdictional wetlands and streams using methodology described in the Washington State Wetlands Identification Manual (WADOE, March 1997). This is the methodology currently recognized by the King County, the City of Renton and the State of Washington for wetland determinations and delineations. The Washington State Wetlands Identification Manual as well as the 1987 Federal Manual requires the use of the three -parameter approach in identifying and delineating wetlands. A wetland should support a predominance of hydrophytic vegetation, have hydric soils and display wetland hydrology. To be considered hydrophytic vegetation, over 50% of the dominant species in an area must have an indicator status of facultative (FAC), facultative wetland (FACW), or obligate wetland (OBL), according to the National List of Plant Species That Occur in Wetlands: Northwest (Region 9) (Reed, 1988). A hydric soil is "a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part." Anaerobic conditions are indicated in the field by soils with low chroman (2 or less), as determined by using the Munsell Soil Color Charts; iron oxide mottles; hydrogen sulfide odor and other indicators. Generally, wetland hydrology is defined by inundation or saturation to the surface for a consecutive period of 12.5% or greater of the growing season. Areas that contain indicators of wetland hydrology between 5%-12.5% of the growing season may or may not be wetlands depending upon other indicators. Field indicators include visual observation of soil inundation, saturation, oxidized rhizospheres, water marks on trees or other fixed objects, drift lines, etc. Under normal circumstances, indicators of all three parameters will be present in wetland areas. 3.0 OBSERVATIONS 3.1 Existing Site Documentation Prior to visiting the site, a review of several natural resource inventory maps was conducted. Resources reviewed included the King County Soil Survey, King County Sensitive Areas Folio: Wetlands, King County Sensitive Areas Folio: Streams, City of Renton Inventory and the National Wetland Inventory. 3.1.1 King County Soil Survey According to the King County Soil Survey, the site contains Alderwood gravelly, sandy loam (AgQ, which typically occurs on slopes of 6-15 percent. Alderwood soils. are moderately well drained, and were formed under conifers, in glacial deposits. According to the publication "Hydric Soils of the United States," Alderwood soils are not considered Hydric or wetland soils.

A low depressional draw near the center of the property extends from the southern property boundary to the northern property boundary. Re: Jolmseine Property SWC Jab# A6-209 October 10, 2006 Page 6of8 3.3 Uplands The upland portion of the site is typical of disturbed urban areas sites. The western portion of the property appears to have been historically cleared and graded in association with the existing single family residence. The eastern portion of the property has a deciduous forested canopy predominantly comprised of red alder (Alnus rubra) with a shrub underbrush dominanted by Himalayan blackberry (Rubes armeniacus). Other species located within the upland areas include beaked hazelnut (Corylus cornuta), red elderberry (Sambucus racemosa), holly (Ileac sp.), and snowberry (Symphoricarpos albus), Soil pits excavated within the upland areas of the site generally revealed a 16 -inch layer of gravelly, silt loam. Two recorded data points within upland areas revealed colors of 10YR 316 and I OYR 413. These areas were dry within 16 -inches of the soil surface during the time of our field investigation. 3.4 Wetland AIB Wetland AIB was flagged with pink "Wetland Delineation" flagging labeled A-1 through A-12 (western wetland edge) and B-1 through B-14 (eastern wetland edge.) Wetland AB is located near the center of the property and extend off-site to the north of the property and to the south of the property. Wetland AIB is a scrub -shrub and emergent wetland located near the center of the property. Although there are some tree species located within the wetland there are not enough trees greater than 20 -feet tall to comprise a forested wetland class. Dominant vegetation within Wetland AIB includes black cottonwood (Populus balsamifera), red alder (Alnus rubra), sahmonberry (Rubes spectabilis), hard hack (Spiraea douglasu), Himalayan blackberry (Rubus armeniacus), reed canary grass (Phalaris arundinacea), manna grass (Glyceria elata), skunk cabbage (Lysichitum americanum), soft rush (Juncus effusus), and buttercup (Ranunculus repens). Soil pits excavated within the wetland revealed a silt loam A -horizon with a color of l OYR 211; an underlying sandy, silt loam B -horizon revealed a color of 5Y 512. Soils within the wetland were typically saturated within 12 -inches of the soil surface during the time of our site visit. According to the United States Fish and Wildlife Service (USFWS) wetland classification method (Cowardin et al. 1979), Wetland AB would be considered a PSS1C (palustrine, scrub -shrub, broad-leaved deciduous, seasonally flooded), and PEM IC (palustrine, emergent, persistent, seasonally flooded) wetland. According to the King County Code (KCC §21A.24.380), Wetland AIB would be considered a Category 3 wetland based on an overall score of 46 (Water Quality 22, Hydrologic 7, Habitat 17) on the adopted Department of Ecology Wetland Rating Form for Western Washington. Typically, Category 3 wetlands with habitat scores less than 20 points and located within the urban growth area have 75 -foot buffer measured from the wetland edge. A 15 -foot building setback line (BSBL) is measured from the buffer edge. Re: John -wine Property SWC Job# A6-209 October 10, 2006 Page 7 of 8 Wetlands located within the urban growth area may receive a 25 -foot buffer reduction if all criteria pursuant to §21A.24.325 are followed. According to the City of Renton Municipal Code (RMC §4-3-050(B)(7)), Wetland AIB would be considered a Category 2 wetland due to is size being greater than 2,200sf and not being classified as a Category I or Category 3 wetland. Typically, Category 2 wetlands have a 50 -foot buffer treasured from the wetland edge (RMC§4-3-050(M)(6). 3.6 Wildlife and Habitat per Renton Study Requirements Research for wildlife species included field investigations and research of the Washington Fish and Wildlife habitat inventories. The site can be broken into two distinct vegetative communities based on the site visit and review of the aerial photographs provided by King County I -map and the City of Renton 2003 aerial photo. (Note: these sketches are not to scale and do not represent surveys of the mapped vegetative communities.) Re: Johnseine Property SWC .rob# A6-209 October 14, 2006 Page 8 of 8 No threatened or endangered species were observed during the time of our site visits. Likewise, no identifiable visual signs of any endangered or threatened species were observed on the property. A search of the Washington Department of Fish and Wildlife Habitat and Species Map for King County and. Vicinity did not reveal any Endangered, Threatened or Sensitive species located on or near the site. The inventory does reveal a State Candidate Species site located approximately 2 miles to the northeast of the site. 4.0 Proposed Project The proposed project is a single family subdivision. Under the King County Code the project has been designed to avoid impacts to the wetland and its associated buffer by utilizing the mitigation measures set forth by §21A.24.325. Therefore; with the 25 -foot buffer reduction the project will avoid impacts to the critical area. Upon acceptance of the conceptual mitigation plans, a final mitigation plan will detail the plant species, size, location, monitoring requirements of any degraded area within the reduced wetland buffer. Under the Renton Municipal Code the proposed project will avoid impacts to the wetland and its associated buffer.

Has the wetland been documented as a habitat far any Federally listed Threatened or Endangered plant or animal species (TIE species)? For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland been documented as habitat for any State listed Threatened or Endangered plant or animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. SP3. Does the wetland contain individuals of Priority species listed by the WDFW or the state? SP4. Does the wetland have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydrog_eomorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands in to those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands, Wet]and Ratine Form — westem Washington f 111041 Page I of 8 Wetland Name: Classification of Vegetated Wetlands for Western Washington Date: 1. Are the water levels in the wetland usually controlled by tides (i.e. except during floods)? N�O — go to 2 YES — the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) If your wetland can he classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and lI estuarine wetlands have changed (see p. ). 2. Is the topography within the wetland flat and precipitation is only source (>90%) of water to it. ®O — go to 3 YES — The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the wetland meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of open water (without any vegetation on the surface) where at least 20 acres (8ha) are permanently inundated (ponded or flooded); At least 30% of the open water area is deeper than 6.6 (2 m)? FO—F go to 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe) 4. Does the wetland meet all of the following criteria? The wetland is on a slope (slope can be very gradual). The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep). Fol —go to 5 YES — The wetland class is Slope 5. Is the wetland in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river? The flooding should occur at least once every two years, on the average, to answer "yes". The wetland can contain depressions that are filled with water when the river is not,flooding. �O — go to 6 YES -- The wetland class is Riverine 6. Is the wetland in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO — go to 7ES — The wetland class is Depressional 7. Is the wetland located in a very flat area with no obvious depressional and no stream or river running through it and Providing water. The wetland seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. No — go to 8 YES — The wetland class is Depressional Your wetland seems to be difficult to classify. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. Sometimes we find characteristics of several different hydrogeomorphic classes within one wetland boundary. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland being rated_ If the area of the second class is less than 10% classify the wetland using the first class.

The general location of the project site is shown on Plate 1 — Vicinity Map. Over most of the eastern two thirds of the site is a wetland and its buffer zones. We understand that the proposed development for the site is to plat the western portion of the site outside of the wetland buffer zone into eight single-family residential building lots. The site is bounded by 148th Avenue SE to its west and adjoined by residential developments on the other sides. The building lots of the subject plat will be accessed from 148th Avenue SE via a short roadway with a cul-de- sac turn -round in the middle of the to -be -developed western portion of the site and a driveway from the cul-de-sac to the southern lots. A stormwater detention vault is to be located near the southwest corner of the site to store storm runoff collected over the impervious surfaces of the proposed development of the site. 19213 Kenlake Place NE - Kenmore, Washington 98028 Phone (425) 483-9134 - Fax (425) 486-2746 November 10, 2008 Plat of Pleasant Path L&A Job No. 8AO98 Page 2 The purpose of this investigation is to characterize the subsurface conditions of the site and provide geotechnical recommendations for the design of the roadway and driveway and the stormwater detention vault. We did not conduct subsurface exploration on the site with test pits or test borings. Instead, this geotechnical investigation is based on the geologic and soil conditions shown on a published geologic map and our experiences of previous projects in the general area of the subject plat site. Presented in this report are our findings of the subsurface conditions and our recommendations. SITE CONDITIONS SURFACE CONDITIONS The subject plat site is situated on the top of a broad, gentle to very -gentle, westerly to southwesterly declining slope flanking the western fringe of a broad, southeasterly trending highland. A wetland traverses roughly south -southeasterly through the middle of the site. As shown on Plate 2 — Site and Plat Plan, the terrain within the site generally slopes down very gently at 2 to 8 percent grade from its east boundary westward towards the wetland, and again from the wetland towards its west boundary. The site is currently occupied by a single-family residence with a separate garage and a work shop within the northwestern quadrant of the site. We understand these existing structures will be demolished for the proposed development of the site. The area surrounding the existing structures is cleared and covered with sporadic grass. The eastern portion of the site is dotted with young deciduous trees and covered with dense underbrush. GEOLOGIC SETTING AND SOIL CONDITIONS The Geologic Map of the Renton Quadrangle, King County, Washin tion, by D. R. Mullineaux, published by U. S. Geological Survey in 1965, was referenced for the geologic and soil LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path L&A Job No. 8AO98 Page 3 conditions of the subject plat site. According to this publication, the surficial soil unit at and in the vicinity of the site is mapped as Ground Moraine (Qgt), as shown on Plate 3 — Geologic Map. The geology of the Puget Sound Lowland has been modified by the advance and retreat of several glaciers in the past and subsequent deposits and erosion. The latest glacier advanced to the Puget Sound Lowland is referred to as the Vashon Stade of the Fraser Glaciation, which has occurred during the later stages of the Pleistocene Epoch and retreated from the region some 14,500 years ago. The ground moraine soil unit is composed of a thin layer of ablation till over lodgmont till, deposited by Puget glacial lobe of the Vashon Stade of the Fraser Glaciation. The underlying lodgmont till is generally a compact mixture of unsorted clay, silt, sand, gravel and cobble, commonly referred to as "hard pan". The surficial ablation till is similar to lodgmont till, but is much less compact and coherent. The thickness generally varies from 2 to 4 feet for the ablation till deposit, and 5 to 30 feet for the lodgmont till deposit. The lodgmont till deposit is practically impervious, except local lenses of sand and gravel. It has a compressive strength comparable to that of low-grade concrete and can stand in steep natural or cut slopes for a long period. The lodgmont till can provide excellent foundation support with little settlement expected. The overlying ablation till is generally in a looser state, and is more compressible and permeable. GROUNDWATER CONDITION The very -dense, weakly -cemented lodgmont till deposit underlying the site at shallow depth is of extremely low permeability, and would perch stormwater infiltrating into the more permeable surficial soils. The amount of and the depth to this near -surface perched groundwater would fluctuate seasonally, depending on precipitation, surface runoff, ground vegetation cover, site LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path L&A Job No. 8A098 Page 4 utilization, and other factors. The perched groundwater may dry up completely during the dryer summer months and accumulate and rise in the wet winter months. DISCUSSIONS AND RECOMMENDATIONS GENERAL The to -be -developed area in the western portion of the site is most likely mantled by a thin layer of topsoil, underlain by a layer of ablation till of medium -dense silty sand to about 2 to 3 feet deep, which is in turn underlain by a lodgmont till deposit of very -dense, weakly -cemented, gravelly, silty sand with occasional cobble. The to -be -developed area is gently to very -gently sloped. The underlying very -dense lodgmont till soils are of very -high shear strength and are capable of providing excellent foundation support to the proposed storinwater detention vault and the residential buildings to be constructed on the site. Conventional footing foundations constructed on or into the lodgmont till soils may be used to support the stormwater detention vault and the buildings. SITE PREPARATION AND GENERAL GRADING Vegetation should be cleared and grubbed within construction limits and should be preserved and maintained beyond construction limits. Topsoil and loose to medium -dense ablation till soils in the to -be -developed areas of the site should be completely stripped down to the very -dense lodgmont till soils within building pads of the building lots, and topsoil and the unsuitable soils in the root zone should be stripped down to the medium -dense ablation soils and/or the lodgmont till soils within the paved roadway/driveway. Fill, if required for grading, should be constructed on proof -rolled, unyielding, undisturbed, firm native soils following the stripping of the surficial unsuitable soils. LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path. L&A Job No. 8AO98 Page S SEISMIC HAZARD AND DESIGN CONSIDERATION The Puget Sound region is in an active seismic zone. The subject site is underlain at shallow depth by very -dense lodgmont till soils of very -high shear strength. There is a lack of continuous, extensive, static groundwater table at shallow depth under the site. The site is generally gently to very -gently sloped. The combination of the above makes it rather unlikely for seismic hazards, such as landslides, liquefaction or soil lateral spreading, to occur on the site during strong earthquakes. Therefore, the seismic hazard of the site should be minimal. The residential buildings to be constructed on the site, however, should be designed to withstand seismic forces induced by strong earthquakes. Based on the soil conditions encountered by the test pits, it is our opinion that Seismic Use Group I and Site Class D should be used in the seismic design of the proposed residences in accordance with the 2006 International Building Code (IBC). EXCAVATION AND FILL SLOPES Under no circumstance should excavation slopes be steeper than the limits specified by local, state and federal safety regulations if workers have to perform construction work in excavated areas. Unsupported temporary cuts greater than 4 feet in height should be no steeper than 1 H:1 V in topsoil and ablation till soils, and no steeper than 1/2H:1 V in the underlying lodgmont till soils. Pennanent cut banks should be no steeper than 2H:1 V in topsoil and ablation till soils, and no steeper than 1-1/4H:1 V in the underlying very -dense lodgmont till soils. The soil units and the stability of cut slopes should be observed and verified by a geotechnical engineer during excavation. Permanent fill embankments required to support structural or traffic load should be constructed with compacted structural till placed over undisturbed, proof -rolled, firm, native, fresh till soils after the surficial unsuitable soils are completely stripped. Permanent fill to be placed over LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path L&A .fob No. 8A098 Page b slopes steeper than 15 percent grade should be retained structurally. The exposed ground exceeding 20 percent grade should be benched with vertical steps not exceeding 4 feet tall after stripping of surficial unsuitable soils and prior to placing structural fill. The slope of permanent fill embankments should be no steeper than 2H:1 V. Upon completion, the sloping face of permanent fill embankments should be thoroughly compacted to a non -yielding state with a hoe - pack. The above recommended cut and fill slopes are under the assumption that groundwater seepage would not be encountered during construction. If groundwater is encountered, the construction work should be immediately halted and the slope stability re-evaluated. The slopes may have to be flattened and other measures taken to stabilize the slopes. Stormwater should not allowed to flow uncontrolled over cut and fill slopes. Permanent cut slopes or fill embankments should be seeded and vegetated as soon as possible for erosion protection and long-term stability, and should be covered with clear plastic sheets, as required, to protect them from erosion until the vegetation is fully established. STRUCTURAL FILL Structural fill is the fill that supports structural or traffic load. Structural fill should consist of clean granular soils free of organic, debris and other deleterious substances and with particles not larger than three inches. Structural fill should have a moisture content within one percent of its optimum moisture content at the time of placement. The optimum moisture content is the water content in the soils that enable the soils to be compacted to the highest dry density for a given compaction effort. Onsite clean silty sand to gravelly sand soils, meeting the above requirements, may be used as structural fill. Imported material to be used as structural fill should be clean, free -draining, LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path L&A Job No. 8A098 Page 7 granular soils containing no more than 5 percent by weight finer than the No. 200 sieve based on the fraction of the material passing No. 4 sieve, and should have individual particles not larger than three inches. The ground over which structural fill is to be placed should be prepared in accordance with recommendations in the SITE PREPARATION AND GENERAL GRADING and EXCAVATION AND FILL SLOPES sections of this report. Structural fill should be placed in lifts no more than 10 inches thick in its loose state, with each lift compacted to a minimum percentage of the maximum dry density determined by ASTM D 15 57 (Modified Proctor Method) as follows: Application Within building pads and under foundations Roadway/driveway subgrade Retaining/foundation wall backfill Utility trench backfill STORMWATER DETENTION VAULT % of Maximum Dry Density 95% 95% for top 3 feet and 90% below 92% 95% for top 4 feet and 90% below An underground concrete detention vault is to be constructed near the southwest corner of the site to store stormwater collected over impervious surfaces of the proposed development of the site. The bottom of the vault is to be at about 8 to 15 feet below the existing ground surface. At such depths, the vault pit would be excavated into the very -dense lodgmont till deposit The vault may be supported on footings founded on the lodgmont till soils and an allowable soil bearing pressure of 4,000 psf may be used for the design of the vault footing foundations. LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path L&A Job No. 8A098 Page 8 A drain line consisting of perforated, rigid PVC, drain pipe or slotted, corrugated ADS, drain pipe, at least 6 inches in diameter, should be installed at a few inches below bottom of the perimeter footings of the vault walls to intercept and drain away groundwater which may flow towards the vault. The drain line should have sufficient slope (0.5% minimum) to generate flow by gravity, and water collected in the drain line should be tightlined to discharge into a storm sewer line or a suitable stormwater disposal facility. The vault footing drain line should be completely embedded in washed gravel wrapped in a layer of non -woven filter fabric, such as 14ON by Mirafi Inc. or approved equal. A vertical drainage blanket at least 12 inches thick horizontally, consisting of compacted pea gravel or washed gravel, should be placed against the perimeter vault walls. The remaining backfill behind the vertical drainage blanket should be constructed of structural fill. Alternatively, a vertical drain mat, such as Miradrain 6000 by Mirafi Inc. or equivalent, may be placed against the perimeter vault walls in lieu of the gravel vertical drainage blanket. The vertical drainage blanket or drain mat should be hydraulically connected to the drain line at the base of the vault perimeter walls. Sufficient number of cleanouts at strategic locations should be installed for periodical cleaning of the vault wall drain line to prevent clogging. The perimeter wails of the detention vault would also serve as retaining walls to support cut banks and backfill. The perimeter vault walls capped with a lid would be restrained at their top from horizontal movement and should be designed for at -rest lateral soil pressure. For the condition that groundwater behind the perimeter vault walls can be fully drained by the drain line provided at the base of the walls, we recommend an at -rest soil pressure of 50 pcf equivalent fluid density (EFD) be used for the design of vault perimeter walls. To counter the at -rest soil pressure, a passive lateral soil pressure of 375 pcf EFD may be used, except that the passive pressure within the top 12 inches of the finish subgrade should be ignored. The above passive pressure assumes the backslope of the walls is level or ascending away from the walls. The at- LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path L&A Job No. 8A098 Page 9 rest soil pressure may also be resisted by the friction force between the footings and the subgrade soils based on a coefficient of friction of 0.55. If the site grades are such that it is not feasible to completely drain groundwater behind the vault walls with a gravity drain line system, the hydrostatic pressure on the perimeter vault walls should also be taken into consideration for the design of the vault perimeter walls. For the condition that a perimeter drain line has to be placed higher than the footing level, the perimeter vault walls should be designed for a lateral soils pressure of 50 pcf EFD above the drain line level and a combined lateral soil and hydrostatic pressure of 80 pcf EFD below the drain line level. The above lateral pressures on the walls may be countered by a passive soil pressure of 375 pcf EFD above the drain line and 210 pcf EFD below. The detention vault should also be designed for seismic loading based on a 100 -year seismic event. For seismic design of the detention vault walls, a pseudo static soil pressure diagram of inverted triangle from the finished ground level to the bottom of the foundations should be used. Based on the soil conditions in the detention vault area, we recommend the lateral soil pressure at the top of the triangle be 8H psf for a 100 -year seismic event, where H is the height from finish grade on top of the vault to bottom of footings in feet. A one-third increase in the above recommended allowable soil bearing pressure may be used when considering the seismic loading condition. The above design parameters are unfactored ultimate values. Proper factors of safety should be applied for the design of the vault walls against sliding and overturning failures. LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path L&A Job No. 8A098 Page 10 PAVED ROADWAY/DRIVEWAY Performance of roadway/driveway pavement is critically related to the conditions of the underlying subgrade soils. We recommend that the subgrade soils under the roadway/driveway be treated and prepared as described in the SITE PREPARATION AND GENERAL EARTHWORK section of this report. Prior to placing base material, the subgrade soils should be compacted to a non -yielding state with a vibratory roller compactor and proof -rolled with a piece of heavy construction equipment, such as a fully -loaded dump truck. Any areas with excessive flexing or pumping should be over -excavated and re -compacted or replaced with a structural fill or crushed rock placed and compacted in accordance with the recommendations provided in the STRUCTURAL FILL section of this report. We recommend that a layer of compacted, 718 -inch crushed rock base (CRB), be placed for the roadway/driveway. This crushed rock base should be at least 6 inches for the roadway off 148`h Avenue SE and 4 inches for the driveway off the cul-de-sac end of the roadway. This crushed rock base may be reduced to a 2 -to -3 -inch layer of leveling course consisting of 7/8 -inch crushed rock if the roadway/driveway bases are cut into undisturbed, very -dense, lodgmont till soils. This crushed rock base should be overlain with a 3 -inch asphalt treated base (ATB) topped by a 2 - inch -thick Class B asphalt concrete (AC) surficial course for the roadway and overlain with a 3 - inch -thick Class B asphalt concrete (AC) surficial course for the private driveways. RISK EVALUATION STATEMENT The subject site is underlain at shallow depth by very -dense lodgmont till soils. These soils are of very -high shear strength and the site should be quite stable. It is our opinion that if the recommendations in this report are fully implemented and observed during construction and following the completion of construction, the areas disturbed by construction will be stabilized and will remain stable, and will not increase the potential for soil movement. In our opinion, the LIU & ASSOCIATES, INC. November 10, 2008 Plat of Pleasant Path. L&A Job No. 8A098 Page 11 risk for damages to the proposed development and from the development to adjacent properties from soil instability should be minimal. LIMITATIONS This report has been prepared for the specific application to this project for the exclusive use by Bola Holm Company and their associates, consultants and contractors.

The numbers of these trees correspond to the numbers on the accompanying map and on the data form, but have not been labeled on the trees in the field since this is in feasibility stage at present. Of the total, 15 are in poor condition with the following condition results: Poor condition with root crown decay and thinning crowns — These trees are located in the horse pasture and have suffered damage at the root crown resulting in trunk decay. Either as a result of the root crown damage or as a result of compaction of the soils, or both, these trees are showing symptoms of advanced stages of stress in the form of thinning crowns. Poor condition, lopped with multiple leaders — These trees have been topped or have suffered failure of the terminal leader (same as being topped) resulting in regrowth from the point of topping or failure. Poor condition, trunk decay and crown dieback — This tree is a big -leaf maple with considerable trunk decay in both the lower and upper portions and is showing symptoms of crown dieback. All of these trees listed as being in poor condition are candidates for removal as retaining them would retain hazardous situations and for many, given their state of decline, would only retain trees that would need to be removed in the very near future, after development of the site, when doing so would prove much more difficult.

Special circumstances The Thorn Property is approximately 2.8 acres in size with 87 significant tree scattered across the site. The property currently contains three structures; a large house, a four car garage, and one out building. The existing large house and garage are to be retained as part of the proposed 9 lot short plat. Development of the site requires NE 121st Street to be extended to the east, saving the existing house and garage, and building appropriate house plans for this neighborhood, dictate to a great extent the layout of the lots and their impacts to existing landmark trees. In addition the layout has been carefully considered, retaining a substantially higher proportion of significant trees then is required by city code. Code requires retaining 35 %, this application is proposing 60 % of the significant trees to be retained. 2. Reasonable use of the property: Current zoning of the property is R-4, this zone requires a minimum density of 80% of the allowed net density. The property would allow for 11 lots based on a total site area of 2.8 acres. Given the site plan constraints of saving the existing house and garage, the extension of NE 121St street, and saving 60% of the existing significant tree, this is a reasonable use of the property. 3. Proposed vegetation protection and mitigation measures: All required significant tree protection measures will be applied to this application per RZC 21.72.072. All significant tree replacement requirements will be installed on site per RZC 21.72.080 or per the allowed Fees in lieu subject to the approval of the administrator. 4. Proposed request will not be detrimental to the public welfare or injurious to other property: 60% of the significant trees are proposed to be retained as an integral part of the proposed 9 lot short plat. The proposed trees to be removed are predominantly located on the interior of the property and pose no significant impacts to adjoining neighbors. 7. OTHER PERMITS: A permit from Water District 90 and the City of Renton Sewer District is required for the water and sewer construction. 8. CSWPPP ANALYSIS AND DESIGN: Design of the ESC plan was completed in conformance with Core Requirement #5 per the 2005 KCSWDM. Compliance with the 9 minimum requirements is summarized below. 1. Clearing Limits: Clearing limits have been delineated on sheet 4 of the preliminary civil plans. The clearing limits extend only to those areas that will be disturbed during construction of the subject project. 2. Cover Measures: Temporary and permanent cover measures will be installed. 3. Perimeter Protection: Silt fence will be used for perimeter protection. Silt fence will be installed along the perimeters of those areas that will be receiving silt - laden runoff. 4. Traffic Area Stabilization: A construction entrance will be installed at the entrance to the project site. 5. Sediment Retention: The proposed detention/water quality vault will be used for sediment retention. Sediment retention will be designed per the 2005 KCS WDM Appendix D. Surface Area: Q10 (06083dev.tsf) = 0.38 cfs (See attached KCRTS Flow Frequency Analysis in Section 4B of this Report) SA = 2080 sf/cfs * Qio SA = 2080 sf/cfs * 0.38 cfs = 791 SF SA Provided = 2,660 SF > 791 SF 7:--> OK Dewater Orifice: The dewatering orifice will be placed at the outlet to the vault. The sizing of the orifice is below: As (2h).o.' Ao = 0.6x3600TgD 5 Ao = 2,660 (2 x 3.5)5 294,166 Ao = 0.024 D=24xrAAO D=24x F�OO D = 2.10" 6. Surface Water Collection: Interceptor swales will be used to direct all sediment - laden runoff to the sedimentation vault. 7. Dewatering Control: A note will be on the final design sheets addressing the procedure for discharge/treatment of runoff from dewatering. Dust Control: Dust control will be be implemented should soils become too dry. 9. Flow Control. The proposed detention/water quality facility will be used for sediment retention therefore, discharge from the facility will be per the Conservation (Level Two) Flow Control standard. Design of the SWPPS plan was completed in conformance with Section 2.3.1.4 in the 2005 KCSWDM. The ESC and SWPPS plan contains notes establishing what materials will not be allowed on the site along with notes describing BMPs for treatment of materials that will be on the site. Since no storage of liquids including fuel will be allowed on the site, no spill prevention report and/or clean up report is required. Vehicle maintenance will not be allowed on the site. Storage of construction materials and wastes will be stored within a designated stockpile area. Any concrete waste or waste from sawcutting or surfacing will be discharged to formed areas awaiting installation of concrete or asphalt and/or to a lined sump as specified in the notes and shown on the ESC and SWPPS plan. The contractor shall designate a personas the responsible representative in charge of erosion control and maintenance of all erosion control and stormwater pollution prevention facilities. 9.

Grantors) hereby grants, covenants, and agrees as follows: 1. Owner(s) of the Property shall retain, upfold, and protect the stormwater management devices, features, pathways, limits, and restrictions, known as flow control best management practices ("Flow Control BMPs"), shown on the approved Flow Control BMP Site Plan for the Property attached hereto and incorporated herein as Exhibit A. 2. Owner(s) of the Property shall at their own cost, operate, maintain, and keep in good repair, the Property's Flow Control BMPs as described in the approved Design and Maintenance Details for each BMP attached hereto and incorporated herein as Exhibit B. [b] MAINTENANCE AND OPERATION INSTRUCTIONS FOR PERFORATED PIPE CONNECTION Your property contains a stormwater management flow control BMP (best management practice) called a "perforated pipe connection," which was installed to reduce the stormwater runoff impacts of some or all of the impervious surface on your property. A perforated pipe connection is a length of drainage conveyance pipe with holes in the bottom, designed to "leak" runoff, conveyed to the pipe, into a gravel filled trench where it can be soaked into the surrounding soil. The connection is intended to provide opportunity for infiltration of any runoff that is being conveyed from an impervious surface (usually a roof) to a local drainage system such as a ditch or roadway pipe system. The size and composition of the perforated pipe connection as depicted by the flow control BMP site plan and design details must be maintained and may not be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. The soil overtop of the perforated portion of the system must not be compacted or covered with impervious materials. MAINTENANCE AND OPERATION INSTRUCTIONS FOR RAIN GARDEN Your property contains a stormwater management flow control BMP (best management practice) called a "rain garden," which was installed to mitigate the stormwater quantity and quality impacts of some or all of the impervious or non-native pervious surfaces on your property. Rain gardens, also known as "bioretention," are vegetated closed depressions or ponds that retain and filter stormwater from an area of impervious surface or non-native pervious surface. The soil in the rain garden has been enhanced to encourage and support vigorous plant growth that serves to filter the water and sustain infiltration capacity. Depending on soil conditions, rain gardens may have water in them throughout the wet season and may overflow during major storm events. The size, placement, and design of the rain garden as depicted by the flow control BMP site plan and design details must be maintained and may not be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. Plant materials may be changed to suit tastes, but chemical fertilizers and pesticides must not be used. Mulch may be added and additional compost should be worked into the soil over time. Rain gardens must be inspected annually for physical defects. After major storm events, the system should be checked to see that the overflow system is working properly. If erosion channels or bare spots are evident, they should be stabilized with soil, plant material, mulch, or landscape rack. A supplemental watering program may be needed the first year to ensure the long-term survival of the rain garden's vegetation. Vegetation should be maintained as follows: 1) replace all dead vegetation as soon as possible; 2) remove fallen leaves and debris as needed; 3) remove all noxious vegetation when discovered; 4) manually weed without herbicides or pesticides; 5) during drought conditions, use mulch to prevent excess solar damage and water loss. MAINTENANCE AND OPERATION INSTRUCTIONS FOR BASIC DISPERSION Your property contains a stormwater management flow control BMP (best management practice) called "basic dispersion," which was installed to mitigate the stormwater quantity and quality impacts of some or all of the impervious surfaces or non-native pervious surfaces on your property. Basic dispersion is a strategy for utilizing any available capacity of onsite vegetated areas to retain, absorb, and filter the runoff from developed surfaces. This flow control BMP has two primary components that must be maintained: (1) the devices that disperse runoff from the developed surfaces and (2) the vegetated area over which runoff is dispersed. Dispersion Devices The dispersion devices used on your property include the following as'indicated on the flow control BMP site plan: D splash blocks, D rock pads, D gravel filled trenches, D sheet flow. The size, placement, composition, and downstream flowpaths of these devices as depicted by the flow control BMP site plan and design details must be maintained and may not be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. Dispersion devices must be inspected annually and after major storm events to identify and repair any physical defects. When native soil is exposed or erosion channels are present, the sources of the erosion or concentrated flow need to be identified and mitigated. Concentrated flow can be mitigated by leveling the edge of the pervious area and/or realigning or replenishing the rocks in the dispersion device, such as in rock pads and gravel filled trenches. Vegetated Flowpaths The vegetated area over which runoff is dispersed must be maintained in good condition free of bare spots and obstructions that would concentrate flows.
