The existing site lies within a portion of NW 1/a Section 8, Township 23 North, Range 5 East, in the City of Renton, Washington (see Figure 2 — �, Vicinity Map). The site is approximately 13.2 acres in size. The site stormwater currently discharges offsite to the existing tightline system in Garden Ave N which is conveyed north to Lake Washington. The site is located in a direct discharge basin. The proposed development will include buildings with associated drive aisles, pazking, and landscape. These buildings are to be used primarily for parking garages, retail shops and commercial purposes. As directed by the City of Renton, the hydrologic analysis and ' design will be based on the 2001 Department of Ecology Stormwater Management Manual for Western Washington (Ecology Manual). Conveyance facilities will be based on the 1990 King County Surface Water Design Manual (KCSWDIV�. 1.2 Existing Conditions The existing site consists of asphalt parking lots, existing buildings, and landscape islands (See Figure 3 - Ezisting Conditions). The site is composed of three drainage subbasins, all of which are part of the John's Creek drainage basin which combine in the Garden Ave N tightline system before being discharged to Lake Washington. The existing site direct discharges, and does not contain flow control or water quality facilities with the exception of an oiUwater separator. A more detailed description of each subbasin can be found in Section 4. 1.3 Developed Conditions The proposed development will include buildings with associated drive aisles, parking, and landscape. These buildings are to be used primarily for parking garages, retail shops and commercial purposes. All drainage facilities and water quality treatment facilities were designed to a complete build-out condition, and were designed per the 2001 Department of Ecology Manual and the City of Renton Standards. The proposed , development will consist of asphalt parking, drive aisles, buildings, and landscaping I throughout the entire site (See Figure 4 - Developed Conditions). A more detailed � description of each subbasin can be found in Section 4. The site was divided into three drainage subbasins per the drainage report prepared by ' Berryman and Henigar (BHC), titled South Lake Washington Roadway Improvements — �' Conveyance System Analysis and Design, dated August 2006, with approximately half the site draining west into the tightline system in Park Ave N, and the other half (two subbasins) draining east into Garden Ave N. Baseline and design drainage basin maps from this report are included in the Section 3 for review. {i'&HPac�c,bic. TIR The Larrdrn,q—Han�est Partners ti'ovember 2006 1 1.0 PROJECT OVERVIEW The proposed storm system includes utilization of the existing tightline system where applicable. The site was divided into three subbasins: north, east, and south. The north and south basins are conveyed through a new tightline system before being routed through respective wetvaults for water quality treatment, and then combine before dischazging into Pazk Ave N. The east subbasin is conveyed through the existing tightline system before being routed through a wetvault and discharging into Garden Ave N at the existing point of discharge. I «`&H Pac�c,L�c. TIR The Landi�rg—Han�est Parmers .'�-ovember?006 � 2.0 PRELIMINARY CONDITIONS SUMMARY 2.1 Core Requirements ➢ Core Requirement�l: Discharge at the'.�Tatural Location The BHC report splits Lot 3 into three drainage subbasins, all of which are part of the John's Creek drainage basin. Approximately half the site is proposed to be discharged to Park Ave N while the other half (tvvo BHC basins) are proposed to discharge to Gazden Ave I�T. The north and south basins «-i11 discharge at a stub location into Park Ave I�T as part of the City's South Lake Washington roadway improvements. The east basin conveyance system will utilize the same discharge point into the 48-inch diameter pipe along Garden Ave N. ➢ Core Requirement#2: Off-Site Analysis The off=site analysis is found in Section 3 of this report. Upstream runoff does not enter the Lot 3 site. ➢ Core Requirement#3: Runoff Control The project is exempt from providing formal flow control facilities because it meets the direct discharge requirements found in the 2001 Ecology Manual. The requirements aze listed in Section 4.4 of this report. ➢ Core Requirement#4: Conveyance System The new pipe tightline system is designed with sufficient capacity to convey and contain the 25-year, 24-hour peak flow using the SBUH method for hydrologic analysis. A backwater analysis is included in this report which uses HGL elevations at the discharge points provided by BHC. ➢ Core Requirement#5: Temporary Erosion and Sediment Control Erosion and sediment controls were installed during demolition and pre-loading of the proposed building pads as detailed in the King County Erosion and Sediment Control (ESC) Standards. ➢ Core Requirement#6: Maintenance and Operations King County maintenance standazds are included for flo�� restrictors, catch basins, pipe systems, landscaping, and wetvaults. 1�'&H Pacif c,Inc.

The three subbasins each have a corresponding wetc�ault designed to the 2001 Ecology Manual standards. Ii'81I Paci�c,Inc. TIR The Landing—Harvest Parmers :Vovember 2006 4 3.0 OFF-SITE ANALYSIS 3.1 tipstream Drainage Analysis There is no upstream flow that enters the site. See Figure 3 —E�isting Conditions. 3.2 Downstream Drainage Analysis Existing and proposed do��nstream drainage maps were completed by BHC and included in Section 3 for reference. These maps show the existing and proposed tightline system from Lot 3 to the Lake Washington outfall. These maps include reference to the structures located between Lot 3 and eventual outfall at Lake Washington. The proposed Lot 3 site falls within the John's Creek drainage basin tributary. In the proposed condition, approximately half the site drains west into the tightline system in Park Ave N, and the other half drains east into Garden Ave N. The runoff to Park Ave N flows in a newly proposed 36-inch pipe north for approximately 800 feet before being directed to the northeast for approximately 1,500 feet and entering a 42-inch pipe, a 48- inch pipe, and then discharging into BHC named `Pond B'. The runoff to Garden Ave N flows north in the existing 48-inch pipe approximately 1,500 feet before discharging into BHC named `Pond A'. The ultimate proposed site flows and volume of runoff generated will be similar to the existing condition since the site does not add any new impervious surface. Therefore, the development of Lot 3 would not aggravate a "severe flooding problem" or "severe erosion problem". r F�'&H Pac�c;Inc.

The site is bound to the west by Park Ave ! N, to the east by Garden Ave N, and to the south by N 8�' Street. and the east side of the 'i site is bound by Garden Ave. N. (See Figure 3 - Existing CondiNons). The lot is relatively flat with elevations that range from 28 feet to 33 feet. The existing site area is nearly 94% impervious surface. Soils on the site consist primarily of Urban Land (Ur) which is fill soil. See the Geotechnical Report found in Section 6 for more information on site soils. The site lies outside the 500-year flood plain, per FEMA panel 53033C0977 F, dated may 16�' 1995. Existing Lot 3 => 13.19 acres Impervious surface => 12.36 acres ' Pervious surface => 0.83 acres ' 4.2 Developed Site Hydrology ,I This proposed development of Lot 3 will consist of retail shops and restaurants with an I� asphalt parking lot. Landscaping will be provided around each building and in landscape I islands. The developed site consists of three subbasins: North, South, and East. The �1orth and South subbasins combine and discharge into Park Ave N to the west, and the East subbasin discharges to Garden Ave N (See Figure 4 - Developed Conditions). Develo�ed Lot 3 => 13.19 acres Impervious surface => 12.35 acres Pervious surface => 0.84 acres 4.3 Water Quality The site is required to meet Basic Treatment Facility standards. The three subbasins each have a corresponding wetvault designed to the 2001 Ecology Manual standards. The water quality sizing was performed using StormShed software. This software performs hydrologic modeling using the Santa Barbara Urban Hydrograph (SBUH) method. This method computes a 24-hour hydrograph (flow versus time) based on the WdcH Pacifrc,Inc.

Wetvaults are proposed for each of the three subbasins w�ill be used for water quality treatment. The vaults were sized based on the volume of the water quality design storm using the 2001 Ecology Manual, or 72 percent of the 2-year, 24-hour storm volume. The entire site is routed through wetvaults for water quality treatment except for roof runoff (4.54 acres total) and four sma11 areas (0.38 acres total) of bypass ���hich v��ere not able to be conveyed in the proposed Lot 3 storm system. The StormShed output for each basin is found in this section along with the water quality volume and flow rate calculations. South Basin Impervious area => 0.89 acres Pervious landscape azea => 0.08 acres Total WQ area => 0.97 acres Water Quality Volume required => 4,554 cf A 48' x 16' x 8.4' two celled concrete wetvault is proposed.

TIR The LaratinR—Harvest Partners .�%ovember 2006 � 4.0 RETENTION/DETENTION ANALYSIS AND DESIGN A 120' x 40' x 7.�' two celled concrete weri�ault w-ith interior wall is proposed. One foot of average sediment storage is provided along the entire vault bottom. Preceding each ���etvault is a flow splitter which is designed to send the water quality flow rate to the wetvault and flows exceeding this amount to a bypass line. The type of flow splitter used contains a baffle wall within the catch basin sized to provide the appropriate hydraulic head acting on an orifice sized for the vvater quality flow rate. The orifice is attached to a closed top half-tee riser which is connected to a pipe leading to the �vetvault. The water quality flow rate was sized according to the 2001 Ecology Manual. This rate is computed by multipl}�ing the 2-yr, 24-hr flow rate by a ratio found in Volume 5, Table 4.1 in the Ecology Manual. The ratio is determined by the effective impervious area for each basin. The water qualit�� flow rates for each basin are as follows: Water uality flow rate South Basin 0.13 cfs East Basin 0.30 cfs North Basin 0.66 cfs The flow splitter calculations are found in this section along with plan and profile views of the structure. Oil Control Facility Requirements Calculations were performed to determine if Lot 3 qualified as a "high-use site". Based on average daily traffic (ADT) counts, it was determined this site does not require oil control facilities. The calculations are found in this section. 4.� Detention Flo«�control is not required of Lot 3, since flows from the site will directly discharge to Lake Washington. The project area meets the following requirements for exemption: • The area must be drained by a conveyance system that is entirely comprised of manmade conveyance elements and extends to the ordinary high water line of the receiving water. • Any erodible elements of the manmade conveyance system for the area must be adequately stabilized to prevent erosion. i{'&H Paci�c,Inc.

A o�i N � � <n O1 � o`4m A Ut v, I 5.0 CONVEYANCE SYSTEMS ANALYSIS A1�D DESIGN 5.1 Roof Do��nspout System The building downspouts will bypass the water quality treatment facilities and enter the bypass line directly. The East basin receives 2.92 acres of roof tributary area which enters Garden Ave N. The North and South Basins combine to send 1.48 acres of roof tributary to the Park Ave N system. 5.2 Proposed On-site Conveyance System The project conveyance system is a conventional storm drainage collection system that will collect runoff from the entire site, including asphalt, roof areas, and landscaping via catch basins and pipes. The new pipe system is designed with sufficient capacity to convey and contain the 25- year, 24-hour peak flow using the SBUH method of hydrologic analysis. At the catch basin CB#2B, which is located at the low point in a truck loading dock, the HGL elevation overtops the catch basin lid by approximately 0.07 feet for the 25-year, 24-hour storm event. This is found to be acceptable since this situation does not create an adverse site condition, and the temporary inability to use the truck dock does not create a long term problem. Included in this section is the complete conveyance and backwater analysis for the entire Lot 3 site for the 25-year and 100-year, 24-hour peak flows using the SBLJH method. The corresponding 25-year HGL elevations at each discharge point, 27.28 in Park Ave N and 28.33 in Garden Ave N, were obtained from BHC. The corresponding 100-year HGL elevations at each discharge point, 27.92 in Park Ave N and 28.62 in Garden Ave N, were obtained from BHC. A 100-year flood map, Figure 8, is included in this section.

'� SUMMARY GENERAL I This report presents the results of the geotechnical engineering study performed by Kleinfelder, Inc. (Kleinfelder) for the proposed Target retail store, which will be part of , the 40-acre Landing mixed use project in Renton, Washington. I SUBSURFACE CONDITIONS �I''� The nature of the deposition of the soils underlying the site results in variable conditions with limited lateral or vertical continuity. The project site is generally underlain by 5 to ' 10 feet of fill, which underlain by highly variable, discontinuous layers and lenses of ' alluvial and lacustrine soils extending to the full depth explored, or over 120 feet. For engineering purposes, the subsurface conditions can be divided into three major units: • Upper Dense Fill: For pavement support purposes, this zone includes the upper few feet of very dense fill that appears to have been cement treated. This material has provided an excellent subgrade for the existing asphalt pavement areas. • Upper Loose/Soft Soils (Includes lower fill): This zone extends to a depth of about 50 to 60 feet (locally deeper) and is generally composed of loose/soft silty sands and organics with zones of compact sands. These upper soils are considered weak, compressible and/or susceptible to liquefaction. • Lower Primarilv Dense Sands: Below a depth of about 50 to 60 feet (locally deeper), the soils can be assumed to be composed primarily of very dense sands with zones of sand and gravel. However, these soils can contain zones of firm/stiff organics, compact silt, and soft/stiff clay. The depth to groundwater is 6 to 10 feet below the ground surface based on piezometer readings in December 2005. FOUNDATION DESIGN RECOMMENDATIONS • Foundation Type: Based on the presence of the loose/soft upper soils, the main structural loads should be supported on a pile foundation bearing in the lower 66677rSEA6R049.doc Page 1 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. ' I very dense granular soils. Based on costs and other factors, auger cast piles are the typical pile type used in the project area. Thus, the recommendations presented in this report pertain primarily to auger casts piles. Another appropriate pile type is the DeWitt proprietary driven grout pile. The DeWitt pile has several advantages over auger cast piles, particularly for the anticipated ground conditions. Since it is a proprietary pile type, the pile is usually presented by the contractor as an alternative to auger-cast piles with the pile design, required driving resistances and depths to be determined by the contractor. . Auqer Cast Piles: Figure 4 provides allowable axial capacity for auger cast piles accounting for downdrag loads, which may develop after a major seismic event. Based on the assumed building loads presented in the Target Developer Guideline version 2.5, building interior columns could be supported on single 18- inch auger cast piles with about 30 to 35 feet of penetration into bearing or two 14-inch piles with about 20 to 25 feet of penetration. The perimeter columns and slab could be supported on single 14-inch piles with about 16 to 18 feet of penetration into bearing. We recommend that the top of bearing be assumed to occur at 60 feet below the current ground surface except for the eastern 75-feet of the building, where bearing should be assumed to occur at a 75 feet. It may be possible to modified these depths during installation based on the drilling action. . DeWitt Piles: As discussed above, the DeWitt pile is a driven grout pile and will obtain the design capacity with less penetration into the bearing zone. This is due to both the densification caused by driving and the fact that the driving resistance data allows us to be confident that the pile is not terminated in one of the looser/softer zones within the otherwise very dense bearing stratum. Based on discussions with DeWitt, who have installed piles in the area, it is likely that the DeWitt piles will require a smaller diameter and/or less penetration to meet the design load criteria as compared to auger cast piles. The DeWitt piles will also need to be designed for downdrag loads, which includes correcting the required driving resistances to account for the resistances in the upper 60 feet reversing into a downdrag load in the event of an earthquake and liquefaction. . Lateral Load Resistance: Lateral load resistance can be developed as passive pressures against the pile caps and grade beams and in the lateral stiffness of 66677/SEA6R049.doc Page 2 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. the piles. Base friction cannot be used due to the slab and structure being pile supported. Section 4.3.3 presents design recommendations for lateral load resistance including effects of liquefaction. OTHER DESIGN RECOMMENDATIONS Sections 4.4 through 4.10 present general design recommendations rated to slabs, under drains, retaining walls, earthwork, utilities and pavements. In general, these recommendations are typical for any Target Development. Section 4.8 presents some recommendations related to minimizing utility damage due to long-term or post liquefaction settlement. CONSTRUCTION RECOMMENDATIONS Section 5.0 presents general geotechnical construction recommendations. In general, these recommendations are typical for any Target Development. Section 5.1 and 5.2 present some specific recommendations related to pile installation and monitoring. � � i � , � � , , � `� ; , � 66677/SEA6R049.doc Page 3 of 24 March 1,2006 Copyright 2006 Kleinfelder, Inc. I 1.0 INTRODUCTION ' 1.1 GENERAL I This draft report presents the results of the geotechnical engineering study performed I, by Kleinfelder, Inc. (Kleinfelder) for the proposed Target retail facility as part of The Landing mixed use development. The proposed Target building will be located northwest of the intersection of 8th Street and Garden Avenue NE in Renton, Washington, as shown on the Vicinity Map, Figure 1. The purpose of this report is to provide geotechnical data and recommendations suitable for design and construction of the Target store in accordance with the Target Developer Guide Version 2.5. 1.2 PROJECT DESCRIPTION Based on the conceptual site plan for Target facility provided by Callison Architecture, Inc. dated January 26, 2006, the project will consist of a 126,000 square foot retail store, light and heavy duty pavement areas, underground utilities, light poles, signs, decorative sidewalks and walkways, and landscape areas. The Target facility will be a portion of the much larger Landing development that will include additional retail buildings abutting the western side of the Target building and numerous other retail stores, restaurants and parking areas. Based on the Target Developer Guide, typical column loads range from about 170 to 205 kips (DL plus LL) with typical perimeter column loads of 68 kips (DL plus LL). Slab LL are on the order of 125 psf with pile supported slabs having loads on the order of 60 kips. 1.3 SCOPE OF SERVICES Kleinfelder performed a preliminary geotechnical evaluation of The Landing project site during the summer of 2006, the results of which are presented in a preliminary report titled "Draft Geotechnical Engineering Report, Proposed Lakeshore Landing Development" and dated July 15, 2006. The purpose of our additional geotechnical , investigation was to explore and further evaluate the subsurface conditions at the proposed site and provide geotechnical conclusions and recommendations for design of the Target facility. , The scope of work completed for this project is consistent with that presented in our January 12, 2006 proposal and included a subsurface exploration program consisting of 66677/SEA6R049.doc Page 4 of 24 March 1,2006 I' Copyright 2006 Kleinfelder, Inc. 2 cone penetration tests and five mud rotary borings; laboratory testing and engineering analyses to develop geotechnical recommendations; and preparation this report. Information from previous geotechnical studies completed for the general project area have utilized in preparing this report. These other studies included: • Draft Geotechnica! Engineering Report, Proposed Lakeshore Landing Deve/opment, Renton, Washington prepared by Kleinfe►der dated July 15, 2005. • Geotechnica/ Report, South Lake Washington Roadway lmprovements, Renton, Washington prepared by Kleinfelder dated January 23, 2006. 2.0 FIELD EXPLORATION AND LABORATORY TESTING 2.1 FIELD EXPLORATION During the preliminary investigation for The Landing Development, a total of 50 borings were drilled throughout the site. Eight borings were advanced within the Target building footprint and 6 borings were advanced within the Target parking lot. The supplemental exploration program was conducted to support development of design level � recommendations in accordance with exploration program guidelines presented in Target's Development Guide version 2.5. An additional 5 borings and 2 cone penetration tests were advanced within the building footprint to bring the total number of explorations within the building footprint to 15. The exploration program was discussed with Mr. Loren Braun, who we understand provides third party geotechnical review for Target and has indicated that the proposed exploration plan was appropriate. The exploration locations are shown in the Site and Exploration Plan, Figure 2. Borings B-22 through B-28, B-38 through B-43, and B-50 were completed for The Landing preliminary site investigation in June 2005. The first phase of exploration for this supplemental report included advancing two cone penetration tests to depths of approximately 43 and 57 feet on December 29, 2005. The cones were advanced to provide quality data regarding the strength and liquefaction susceptibility of the loose/soft layers encountered at the site. The cones met refusal on gravel soils and I, were not able to fully penetrate to the depths of the deeper bearing layers. The second ' phase of exploration for this supplemental work included advancing 5 mud rotary borings, designated B-51 through B-55, to depths ranging from 98 to 138�/2 feet. The 66677/SEA6R049.doc Page 5 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. borings were drilled on January 18 through January 27, 2006, under full-time observation of a Kleinfelder geotechnical engineer. Exploration locations were determined in the field using a compass and a 100-foot tape and based on site features - such as the edge of existing roads. The approximate locations of the explorations are ' plotted on the Site and Exploration Plan, Figure 2. Appendix A presents a summary of our exploration program including boring and cone penetration test logs. Additional exploration information for the other areas of the Landing site is available in our July 15, 2005, preliminary report. 2.2 LABORATORY TESTING Laboratory testing was conducted on selected samples obtained from the borings to help characterize the site soils and determine relevant engineering and index properties. Laboratory testing performed for the Target property during the preliminary Landing report and this supplemental Target study included 121 moisture content tests, 7 Atterberg tests, 10 grain-size distribution tests, and 2 consolidation tests. The tests were conducted in general accordance with appropriate American Society for Testing and Materials (ASTM) Standards and the results are presented in Appendix B and displayed on the boring logs in Appendix A, as appropriate. � 3.0 SITE CONDITIONS 3.1 SURFACE CONDITIONS The general project area is bordered on the north by Lake Washington, on the west by the Cedar River, which is located about '/z mile from the site and flows north into Lake Washington, on the east by Interstate 405, and on the south by commercial and residential development that extends into downtown Renton. The project area is primarily used for retail and industrial purposes. The Target site is bordered on the east by Garden Avenue North, on the south by North 8th Street, on the north by a parking lot, and on the west by building pads prepared for other retail development. The site is relatively flat and ranges in elevation from approximately 27 to 30 feet (Mean Sea Level Datum, MSL) with no trending slope; the average elevation of the site is approximately EI. 29 feet. Approximately 2 feet of fill has been placed in the building pad area. 66677,�SEA6R049.doc Page 6 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. The project site was previously occupied by a parking lot. The asphalt and base material have been removed from within the building footprint but asphalt remains in place north of the building. 3.2 REGIONAL GEOLOGY The project site is located at the north end of the Cedar River Valley approximately '/2 mile from where the river enters Lake Washington. Post-glacial geologic conditions at the site are dictated by the presence of Lake Washington and the Cedar River. The channel of the Cedar River is believed to have migrated across the full width of the valley several times since end of the last Puget Sound glaciation and the river used to flow out of Lake Washington before the level of the lake was lowered. Accordingly, site soils are expected to consist of a variable mixture of alluvial (river) and lacustrine (lake) deposits. In general, the river is slow flowing near the lake; therefore, low energy alluvial and over-bank deposits are expected. These generally include clay, silt, peat, organic silt and sand and are typically loose and soft. Lacustrine deposits are lake deposits deposited in a very low energy environment and generally consist of silt and clay and are typically very loose and soft. Organics can be found within both types of deposits and can range from non-fibrous plant matter to fibrous partially decayed timber. Because of the migration of the Cedar River channel and the inherent variability of alluvial deposits, site soils are expected to be highly variable. General geologic information for the project site was obtained from the Geologic Map of King County (Booth, et. al., in press). According to the map, surficial soils at the project site consist of modified land, or fill. Surficial soils near the site that are not covered with fill are mapped as Holocene Alluvium. Holocene Alluvium is a post-glacial river deposit that has not been consolidated by glaciers. 3.3 SUBSURFACE CONDITIONS 3.3.1 General As discussed in Section 3.2, the nature of the deposition of the soils tends to result in variable conditions with limited lateral or vertical continuity. The project site is underlain by 5 to 10 feet of fill underlain by highly variable, discontinuous layers and lenses of alluvial and lacustrine soils extending to the full depth explored by our borings, or over 120 feet. Figure 3 presents a subsurface cross-section through the site. 66677/SEA6R049.doc Page 7 of 24 March 1,2006 Copyright 2006 Kleinfelder,Inc. Generally, loose/soft native soils occur within the upper 50 to 60 feet with the soils I!, below about 60 feet generally being very dense or stiff. The upper loose/soft native ��, soils above a depth of about 50 to 60 feet were composed primarily of layers of silts and �' silty sands with about 30 percent zones of organics and 20 percent zones of clean sands. The lower dense/stiff native soils below a depth of about 60 feet were composed primarily of layers of sands or sands and gravels with about 15 percent zones of soft organics and 15 percent zones of silts, silty sands. On the eastern side of the building area, several borings encountered soft to stiff clays at depth. Several borings encountered deeper soft soils such as boring B-28, which encountered loose silt and soft peat from about 55 to 75 feet and B-54 where soft clay was encountered between about 96 and 100 feet. Based on SPT (Standard Penetration Tests) values generally over 50 blows/foot (b/ft), the granular soils below 50 to 60 feet appear to be advanced deposits over ridden by the glaciers. However, because the lower blow count material including some soft soils were encountered within these soils even at depths over 100 feet, the soils are considered geologically recessional in nature and are not thought to be glacially overridden. 3.3.2 Soi! Types The site soils can be grouped into a total of five different types as follows: . Fill: Fill material was encountered at the ground surface or below the pavement in all borings and generally extended to depths ranging from 5 to 10 feet. In general, the fill consisted of silty sand with gravel or sandy silt with gravel. There appears to be an upper one to three feet of the fill that may have been cement treated based on its very dense consistency and excavation difficulty. In other areas of the site, a D-8 dozer with ripping teeth was used to excavate the fill so that it could be picked up by scrapers. Below this "hard" zone, the fill was variable ranging from loose to dense. • Orc1anic Silt and Peat: The borings encountered layers of peat and organic silt ranging from less than a foot to over 10 feet thick. Within the upper 50 to 60 feet, these soils were generally soft to firm with SPT blow counts in the range of 2 to 6 b/ft. Encountered below depths greater than about 60 feet, the organic layers were generally firm to stiff with SPT values in the range of 10 to 25 b/ft. Many of the borings encountered a 5 to 10 foot zone of these stiff organic layers at a 66677%SEA6R049.doc Page 8 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. depth of about 65 to 70 feet. The geologic explanation of these stiff organic soils is not well understood but may have involved drying and desiccation in a near surface environment before being buried under sediment. • Clay: Several borings on the eastern side of the proposed building encountered 5 to 10 foot thick clay layers at depths between about 75 to over 100 feet. The clay was soft to stiff with SPT values in the range of 5 to 25 b/ft. The geologic explanation of the stiffer clays is not well understood, but may have involved drying and desiccation in a near surface environment before being buried under sediment. • Silt and Silty Sands: The borings encountered zones consisting of silt, sandy silt and silty sands. These soil types were predominate in the upper 50 to 60 feet and decreased in frequency below these depths. In the upper 50 to 60 feet, the soils tended to be loose to compact with SPT values in the range of 2 to 10 b/ft. At depth, the material became compact to dense with SPT values in the range of 10 to 30 b/ft. • Sand and Gravel: The borings encountered zones consisting of clean sand and sand and gravel. These soil types were limited in the upper 50 to 60 feet but were the predominate soil type below these depths. In the upper 50 to 60 feet, the soils tended to be compact to dense with SPT values in the range of 10 to 30 b/ft. At depth, the material became very dense with SPT values generally over 50 bl/ft. The thickness of individual layers of these lower dense soils were generally about 10 to 15 feet in the 50 to 75 foot depth zones and increased to 15 to over 30 feet thick below about 75 feet. 3.3.3 Engineering Units For engineering purposes, the subsurface conditions can be divided into three major engineering units: • Upper Dense Fill: For pavement support purposes, this zone includes the upper few feet of very dense fill that appears to have been cement treated. This material has provided an excellent subgrade for the existing site asphalt pavement areas. 66677/SEA6R049.doc Page 9 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. • U�per Loose/Soft Soils (Includes lower fill): To a depth of about 50 to 60 feet (locally deeper), the soils can be assumed to be composed of loose/soft silty sands and organics with zones of compact sands. These upper soils are considered weak, compressible and susceptible to liquefaction. . Lower Primarilv Dense Sands: Below a depth of about 50 to 60 feet (locally deeper), the soils can be assumed to be composed primarily of very dense sands with zones of sand and gravel. However, the soils can contain zones of firm/stiff organics, compact silt, and soft/stiff clay. 3.3.2 Groundwater Conditions The depth to groundwater was not identified in the majority of borings due to use of mud rotary drilling techniques. Mud rotary drilling involves circulation of a drilling fluid within the borehole, thereby obscuring groundwater seepage that may otherwise be observed in samples and on equipment. However, as part of our work for the adjacent roadway improvement report, we installed and monitored nine piezometers around the general site area. Based on piezometer readings obtained in December 2005 for another project in the immediate area, the depth to groundwater is 6 to 10 feet below ground surface. Groundwater levels will fluctuate depending the time of the year and are likely to be highest during the wetter winter months. It should be noted that Kleinfelder did not install groundwater monitoring piezometers, nor did we perform a hydrogeologic evaluation at this site. The annual variability in groundwater depth at this site has not been measured. 4.0 CONCLUSIONS AND DESIGN RECOMMENDATIONS ' 4.1 GENERAL As discussed in Section 3.3, the site is underlain by a 50 to 60 foot (locally deeper) loose/soft zone composed primarily of silty sands and organics which are considered weak, compressible and susceptible to liquefaction. Below these upper soils, the borings generally encountered a lower zone of very dense sands with zones of sand and gravel. However, these lower soils can contain zones of firm/stiff organics, compact silt, and soft/stiff clay. We recommend the proposed structure be founded auger cast or DeWitt driven grout piles that bear in the soils primarily comprised of very 66677,'SEA6R049.doc Page 10 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. dense sands. Due to the presence of some variable layers of organics and soft/stiff clay in the lower dense sand, the auger cast piles should be designed as friction piles with a relatively low end bearing capacity. We understand that Target has elected to use structural floor slabs supported on piles rather than preload the site and utilize concrete slab-on-grade floors. The following sections present recommendations for seismic design considerations, pile foundation design and construction, floor slabs, earthwork, drainage, retaining walls and pavements. 4.2 SEISMIC CONSIDERATIONS 4.2.1 Code Based Design We understand that the project will be designed in accordance with the 2003 IBC. The site soils are liquefiable and therefore the site is classified as Site Class F. Section 1615.1 of the IBC does not require that a site-specific response spectrum be developed unless the period of the structure will be greater than �/2 second. Based on our understanding of the proposed structure, we anticipate that the building period will be less than �/2 second and a site-specific response spectrum is not necessary. Accordingly, use of Site Class D is appropriate for developing a design response I spectrum using the General Procedure. Table 1 presents seismic coefficients for use with the General Procedure described in Section 1615 of the 2003 IBC. The seismic ground motion procedure contained in IBC 2003 is based upon a Maximum Considered Earthquake (MCE} with a 2 percent probability of exeedence in 50 years (i.e. recurrence interval of approximately 2500 years). Ground motions for the MCE in the 2003 IBC are linked to probabilistic earthquake hazard mapping efforts that have been conducted by the United Stated Geologic Survey (Grankel, et. al., 1996, 2002). Parameters presented in Table 1 are based on the latitude and longitude lookup for the 2002 maps provided on the USGS web site. 66677/SEA6R049.doc Page 11 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc.

Design PGA (g) = SpS/2.5 4.2.2 Liquefaction Seismic design parameters in the 2003 IBC are based on a Maximum Considered Earthquake (MCE) with ground motions having a 2 percent chance of being exceeded in a 50 years. This corresponds to an event with a return period of about 2,500 years. As a minimum, all structures must meet life safety requirements when liquefaction is considered for the 2,500 year event. Based on the soil types and low SPT values, the native sand and silty sands in the upper 50 to 60 feet have a high probability of liquefying under the design event. In accordance with Target Developer Guide requirements, we have estimated liquefaction-induced ground settlement under two earthquake scenarios, a lower lever event (LLE) and an upper level event (ULE). The LLE is defined as a ground motion with a 50 percent probability of being exceeded in 50 years and corresponds to a retum period of about 72 years. The corresponding peak ground acceleration for this event is about 0.12g. The ULE is defined as an event with a 10 percent probability of being exceeded in 50 years and corresponds to a return period of about 475 years. The corresponding peak ground acceleration is about 0.32g. As discussed in section 4.2.1, the peak ground acceleration corresponding to the MCE is 0.39g. For comparison purposes, seismographs in the Renton area recorded peak ground accelerations of about 0.05 to 0.10 g during the 2001 Nisqually earthquake. This corresponds to ground shaking levels that are slightly weaker than what is expected for the 72-year event. Liquefaction potential was estimated using the latest available, widely accepted empirical relationships that relate SPT blow counts to liquefaction resistance (Youd et. 66677/SEA6R049.doc Page 12 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. ' al, 2001). The corresponding ground surface settlement was estimated using a volumetric strain method (Ishihara and Yoshimine, 1992). In general, under the LLE, ground surface settlements could be on the order of 3 inches. Under the ULE and MCE events, ground surface settlements could be on the order of 6 inches or more. Liquefaction induced settlement estimates assume a uniform liquefiable layer and should only be considered approximate. We do not anticipate that liquefaction settlement will pose a life safety hazard for pile-supported structures. � 4.2.3 Fault Rupture In our opinion, the probability of fault rupture at the site is low because there documented active faults near the project site. 4.2.4 Landsliding and Lateral Spreading In our opinion, the probability of landsliding or lateral spreading at the site is low due to the relative flatness of the site and lack of a widely continuous layer of liquefiable soil. 4.3 FOUNDATION RECOMMENDATIONS 4.3.1 General Based on the presence of the loose/soft upper soils, the main structural loads should be supported on a pile foundation bearing in the lower very dense granular soils. Since the location of these softer, looser zones is variable and does not appear to be laterally continuous, the auger cast pile capacity calculations need to assume that some zones of organics and soft clays may be present and the piles should be designed as friction piles with a relatively low end bearing capacity. Several of the other buildings to be constructed at the Lakeshore Landing site will utilize a preload to limit post construction static settlement with the floor slabs supported on grade. This preload, slab-on-grade design will be susceptible to earthquake induced liquefaction settlements as discussed Section 4.2. We understand that Target has made the decision to use a pile supported structural slab based on preload schedule constraints and the preference to eliminate the risk of liquefaction settlement damage to the floor slabs. Due to the liquefaction risks, the piles must be designed to account for post earthquake downdrag loads. Several pile types are technically feasible including driven piles and auger cast piles. Driven pile types could include close end steel pipe piles and pre-cast concrete piles. Based on costs and other factors, auger cast piles are the typical pile type used in the 66677/SEA6R049.doc Page 13 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. area. Thus, the recommendations presented in this section pertain primarily to auger casts piles. Another appropriate pile type is the DeWitt proprietary driven grout pile. The pile involves a mandrel driven casing, which after driving to the required tip elevation, is grouted under pressure as the casing is removed. This results in a continuous grout pile similar to the auger case pile. The DeWitt pile has several advantages over auger cast piles, particularly for the anticipated ground conditions. Since the DeWitt pile is a driven pile, pile driving information is obtained which can be used to insure that the pile tip is bearing on a dense bearing layer and not on one of the looser/softer zones that are present at depth. In addition, the driven piles densify the surrounding soils and develop a higher capacity for a given diameter as compared to auger cast piles. DeWitt piles also generate limited spoils as compared to auger cast piles. Since the DeWitt pile is a proprietary pile type, the pile is usually presented by the contractor as a pile alternative with the pile design, required driving resistances and depths to be determined by the contractor. The contract would require that the contractor demonstrate an equivalent pile capacity and performance to the auger cast piles. This is normally accomplished by one or more pile load tests combined with pile driving resistance information provided by the contractor from other pile projects in the area. Normal minimum pile spacing should be 3 times the pile diameter. 4.3.2 Auger Cast Axia! Compression Pile Capacity Allowable axial compression capacities for auger cast piles were calculated based on the possibility that the auger cast pile tip could be bearing on one of the softer/looser _ zones within the otherwise very dense sand bearing stratum. Thus, we assumed a nominal allowable end bearing capacity of 8 ksf and reduced the average allowable adhesion value to 1.5 ksf in the bearing zone. For the downdrag calculation, we assumed that the zones of liquefied soils would cause settlement but would have limited strength. Thus the main downdrag loads came from the zones of fill, compact sands, and organics, which will not liquefy but will settle in the event that underlying soils liquefy and decrease in volume. Figure 4 presents a plot of allowable axial compression capacity versus embedment in to the bearing soils. We recommend a minimum penetration of 10 feet into bearing soils and a minimum pile diameter if 14-inches. Based on Figure 4, the interior columns (DL plus LL 170 to 205 kips) could be supported on single 18-inch auger cast piles with about 30 to 35 feet of penetration into bearing or two 14-inch piles with about 20 to 25 66677/SEA6R049.doc Page 14 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. feet of penetration. The perimeter columns (68 kips DL plus LL) could be supported on single 14-inch piles with about 18 feet of penetration with the slab (60 kips loads) supported on single 14-inch piles with about 16 feet of penetration. Normal minimum pile spacing should be 3 times the pile diameter. The depth to bearing is variable across the site and needs to be conservatively estimated since it may not be apparent when bearing is encountered during pile installation. We recommend that the top of bearing be assumed to occur at 60 feet below the current ground surface except for the eastern 75-feet of the building where bearing should be assumed to occur at a 75-foot depth. It may be possible to modified these depth during installation based on the drilling action. 4.3.2 DeWitf Axial Compression Pile Capacity As discussed above, the DeWitt pile is a driven grout pile and will obtain the design capacity with less penetration into the bearing zone. This is due to both the densification caused by driving and the fact that the driving resistance data allows us to be confident that the pile is not terminated in one of the looser/softer zones within the otherwise very dense bearing stratum. Since the DeWitt pile is a proprietary pile type, the estimated pile depths and allowable capacities should be determined by the contractor and demonstrated to the owner through pile loads tests combined with pile driving resistance information from other pile projects in the area. Based on discussions with DeWitt who have had experience in the area, it is likely that the required DeWitt piles will have a smaller diameter and/or less penetration to meet the design load criteria. The DeWitt piles will also need to be designed for downdrag loads, which includes correcting the required driving resistances to account for the resistances in the upper 60 feet reversing into a downdrag load. 4.3.3 Settlement In general, settlement of auger cast piles bearing in the very dense sands should be minimal, on the order of 1/2 inch. Since the auger cast piles are designed based on minimal end bearing, occurrence of any softer zones near the pile tip, such as encountered in boring B-52 from 96 to 105 feet, should not adversely impact settlement. In general, settlement of driven DeWitt piles bearing in the very dense sands should also be minimal, on the order of '/2 inch. In fact, the DeWitt plies should generally settle ; 66677iSEA6R049.doc Page 15 of 24 March 1, 2006 I Copyright 2006 Kleinfelder, Inc. less than the auger cast piles since they are driven piles. However, DeWitt piles will likely be designed to utilize a significant end bearing component. Thus, the presence of compressible soils below the tip could impact settlement. We assumed that any compressible soils within about 3 to 4 feet of the pile tip would be evidenced in a reduced driving resistance and as a result the pile would be driven through the compressibte layer. Pile settlement estimates were developed based on an assumed thickness and compressibility of a compressible zone, and assuming the zone is located about 4 feet below the pile tip. The results indicate that the theoretical increase in settlement, even for this unlikely case, would be less than �/a inch for a single 18-inch diameter pile. However, the theoretical settlement will be higher for a multi-pile group. Assuming a group of four 18-inch diameter piles with a center-to-center spacing of 4.5 feet, we estimated an additional settlement of about '/rinch in addition to that estimated for a single pile. In general, based on the current pile loads and capacities, it is unlikely that pile groups larger than two piles would be required. However, if larger pile groups are required, Kleinfelder should be notified and have the opportunity to review the design and possible implications of the design. 4.3.4 Latera! Resistance Lateral load resistance can be developed as passive pressures against the pile caps and grade beams and in the lateral stiffness of the piles. Base friction cannot be used due to the slab and structure being pile supported. For resisting lateral loads we recommend the following: • Passive Pressures: Allowable passive pressures on the sides of the grade beams and pile caps can be calculated assuming a fluid with a density of 250 pcf with a 1/3 increase for transient loads. This value assumes that any backfill against the foundation elements will be properly compacted as discussed in Section 4.7. For exterior foundation elements, the upper 18-inches should be neglected unless the paving extends up to the building. • Lateral Pile Resistance: The lateral resistance on vertical piles can be evaluated using programs such as LPILE, which model the load-deformation behavior of the soil-pile system. Recommended parameters for LPILE analyses assuming no liquefaction are presented in Table 2. 66677/SEA6R049.doc Page 16 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc.

Typically, the structural engineer will use the full, non-liquefied parameters with the full response spectra as the main seismic case evaluated. To assess liquefaction, he will often use a reduced response spectra (typically '/2 to 1/3 the peak) with the liquefied LPILE parameters. Recommended parameters for LPILE analyses assuming liquefaction and a reduced ground response spectra are presented in Table 3. For the , , liquefied case, the liquefied sands are modeled as a soft cohesive soil with the undrained strength based on published data for liquefied sands.

We recommend a capillary break consisting of at least 6-inches of 3/4 inch minus well graded base material containing no more than 5 percent passing the Number 200 U.S. standard sieve size. The layer should be compacted to at least 95 percent compaction based on the modified Proctor (ASTM D 1557). We recommend the capillary break be 66677/SEA6R049.doc Page 17 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. overlain by a vapor barrier consisting of a minimum 10-mil plastic sheet overlapped at II least 12 inches at the seams. A layer of sand can also be placed over the vapor barrier if required by the structural engineer or recommended by the contractor. 4.5 DRAINAGE RECOMMENDATIONS Building underdrains are generally not required since the slab will be at or above the adjacent exterior ground surface. Footing drains are recommended only adjacent to a depressed loading dock area as discussed in Section 4.8. Due to the depth to the groundwater table and the granular nature of the fill material, special pavement under drain provisions are not recommended except in loading dock areas. 4.6 EARTHWORK 4.6.1 Existing Subgrade Condifions The building pad was constructed by remo�ing asphalt parking lot pavement from within the building area and excavating some of the existing subgrade soils for use as pre-load surcharge fill elsewhere on the site. The pad elevation was subsequently raised approximately 1 to 2 feet with fill. � Subgrade exposed after removal of the asphalt and during excavation consisted of a variable mixture of silt, sand, gravel and recycled concrete material. The subgrade was very compact as evidenced by firm and unyielding solid support and lack of rutting under heavy construction equipment traffic including scrapers and off-road dump trucks. Excavation was accomplished by a large track hoe excavator with ripping teeth and a D- 9 Bulldozer. Fill placed to raise the building pad was evaluated by Kleinfelder on a performance basis rather than by density testing due to the highly variable grain size content that would have made reliable testing difficult. The fill consisted of a well-graded mixture of sand, gravel and recycled asphalt and concrete and was placed in lifts with a maximum thickness of approximately 8-inches. The fill was trafficked by scrapers and continuously compacted during placement with a ride-on double smooth drum roller. During recent prolonged heavy rains the pad has remained firm and provided solid support for drilling equipment. In our opinion, the pad will provide adequate support for construction activates and material lay down areas. The building pad is not suitable for supporting concrete slab- 66677/SEA6R049.doc Page 1 S of 24 March 1,2006 Copyright 2006 Kleinfelder, Inc. I on-grade floors or structures due to the presence of the underlying soft, compressible and liquefiable soils. 4.6.2 Excavation Kleinfelder performed part-time observation of exca�ation and demolition of the existing storm water utilities within the building pad. The excavations encountered dense to very dense fill soils that exhibited a cementation behavior. Excavation for site utilities will encounter the dense to very dense building pad and pre-existing fill soils. These soils will require significant excavation effort. We recommend use of large track hoe excavators with narrow buckets and/or ripping teeth. Backhoes will generally be inefficient at excavating through the hard layer of fill soils and the contractor should be aware of these potentially difficult excavation conditions. 4.6.3 Grading Recommendafions The site is essentially flat thus design permanent cut and fill slopes are not required. We anticipate that fills to re-establish grade around the building pad will be on the order of 2 feet or less. Typically, the recommended maximum landscape slopes would be 3H:1 V, depending on landscape requirements. 4.7 STRUCTURAL FILL MATERIALS AND COMPACITON All material placed in parking lots should be considered structural fill. Structural fill should consist of well-graded, free-draining sand and gravel free from organics or other deleterious matter and have a maximum particle size of 6 inches. We anticipate that any material graded from the existing pad will be suitable for use as structural fill. Imported structural fill material should conform to Section 9-03.14(1), Gravel Borrow, of the Standard Specifications. The contractor should submit samples of each of the required earthwork materials to the geotechnical engineer for evaluation and approval prior to use. The samples should be submitted at least 4 days prior to their use and sufficiently in advance of the work to allow the contractor to identify alternative sources if the material proves unsatisfactory. Structural fill should be moisture conditioned to within 3 percent of the optimum moisture content prior to compaction and should be placed in maximum 12-inch thick loose lifts. All structural fill should be compacted to a dense and unyielding condition ' 66677iSEA6R049.doc Page 19 of 24 March 1,2006 I�� Copyright 2006 Kleinfelder; Inc. I l and to the following minimum percentages of the modified Proctor maximum dry density as determined per ASTM D1557: Fill below sidewalks: 95 percent Pavement subgrade within 2 feet of finished subgrade: 95 percent Pavement subgrade more than 2 feet below finished subgrade: 90 percent Trench backfill placed within 4 feet of finished subgrade: 95 percent Trench backfill placed more than 4 feet below finished subgrade: 90 percent 4.8 RETAINING WALLS The site is essentially flat thus retaining walls will generally not be required. Locally, such as adjacent to the loading dock area, low retaining walls may be required. The walls can be designed based on the following: . Active Earth Pressure (wall free to rotate): Design based on a fluid with a density of 35 pcf plus any surcharge loads. • At Rest Earth Pressure (wall not free to rotate�: Design based on a fluid with a density of 55 pcf plus any surcharge loads. • Lateral Resistance: See section 4.3.4. 4.9 UTILITY RECOMMENDATIONS Typical design procedures can be used for the utilities based on the City of Renton Standards. As discussed in Section 4.2, there is a potential for liquefaction induced settlement on the order of several inches. Since the building and s►ab are pile supported, sharp differential settlements may occur that damage utilities entering the building. We recommend the following to minimize an adverse effects of liquefaction induces settlements: • Support all interior utilities from the slab. The design needs to account for the load that could be imposed on the utility by backfilled soil settling over and around the utility. We feel that this can best be done by not backfilling around the utility and placing plywood as a form over the utility trench to support the slab pour. A geomembrane such as visqueen should be placed over the plywood to minimize concrete leaks during the slab pour. 66677�SEA6R049.doc Page 20 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. • Use flexible connections wherever a utility transitions from at grade support to pile support. Liquefaction induced settlement is likely to be non-uniform and may result in some utility damage after a major seismic event. These types of risks are normally accepted by the owners since it is considered uneconomical to eliminate the risks. However, the risks can be reduced by providing a more flexible pipes and connections as appropriate. 4.10 TEMPORARY EXCAVATIONS, SLOPES AND DRAINAGE In general, there will be limited cut or fill slopes except as required for utilities or to place foundation elements. All excavations and slopes must comply with applicable local safety regulations. Construction site safety is the sole responsibility of the Contractor, who shall also be solely responsible for the means, methods, and sequencing of construction operations. The contractor should be responsible for the safety of personnel working in utility trenches. We recommend all utility trenches, but particularly those greater than 4 feet in depth, be supported in accordance with the referenced regulations. The contractor is also responsible for maintain a dry excavation including all utility work. This may require dewatering for the deeper utilities. The contractor should be made responsible for insuring proper drainage of surface runoff during construction. The contractor should maintain grades such that there is not unwanted ponding of water anywhere on the site. All collected water should be conveyed under control to a positive and permanent discharge system, such as a storm sewer. The contractor should be required to submit in writing is plan for construction drainage. 4.11 PAVEMENTS A majority of the project site is currently paved. Based on pavement exposures at the edges of the areas where pavement has been removed, the existing pavements range from approximately 4 to 6 inches thick. We understand that most of the existing pavements will be overlaid with approximately 1-inch of asphalt to provide an attractive surface and match new pavement grades. Based on our observations, the existing pavements appear to be in good condition as evidenced by lack of cracking and rutting. In addition, these pa�ements have not 66677/SEA6R049.doc Page 21 of 24 March 1,2006 Copyright 2006 Kleinfelder, Inc. developed signs of distress such as cracking or rutting under heavy construction equipment. The existing pavement subgrade soils are very dense and are anticipated to provide soil support to the existing and new pavements. In our opinion, overlying of the existing pavements is feasible. In areas that will require paving, we recommend light duty pavement sections consist of a minimum of 3 inches of asphalt over 4 inches of crushed surfacing and heavy duty pavement sections consist of a minimum of 4 inches of asphalt over 6 inches of crushed surfacing. 5.0 CONSTRUCTION RECOMMENDATIONS 5.1 AUGER CAST PILE INSTALLATION Auger cast piles are particularly sensitive to the installation methods and the contractor's experience. Poor equipment and/or inexperienced contractors can result in piles that are improperly installed and do not adequately support the loads. Thus, it is essential that the auger cast piles be installed by a qualified, experienced contractor with the full-time construction monitoring of an experienced geotechnical field engineer. The contractor should be required to submit in writing the list of equipment and personnel to be used. The pile superintended should have at least 5 years of experience installing these types of piles. General monitoring requirements include the auger down pressure, auger penetration rate, identification of cuttings, the rate of auger withdrawal, grout pressure and grout take. It is also recommended, as a minimum, one nominal diameter rebar be placed full depth into the grout after auger removal as a check on hole "necking". If the rebar cannot be installed to the bottom, the pile should be rejected. The required pile penetration depths presented on Figure 4 assume that it will not be possible based on the drilling action to assess the nature of the soils at the pile tip. If observations can definitively differentiate between the very dense bearing sands and the layers of firm clay/peat, it may be possible to shorten the required pile lengths. The contractor bid should consider the difficulty of drilling through the very dense, partially cemented upper fills. The need for pre-drilling or pre-excavating should be included in his bid as appropriate. The contract should have language to address I 66677/SEA6R049.doc Page 22 of 24 Maroh 1,2006 'I Copyright 2006 Kleinfelder, Inc. encountering obstructions that would likely be shallow enough to be removed with a trackhoe excavator. 5.2 DRIVEN GROUT PILE INSTALLATION Since the DeWitt driven grout pile is a proprietary pile, the contractor is responsible for the design of the piles, required depth of penetration, required driving resistance and pile performance. In addition to the design and installation criteria, the contractor should be required to submit in writing the list of equipment and personnel to be used. The estimated pile depth, capacity and driving criteria should be supported with at least two pile loads tests combined with pile driving resistance information from other pile projects in the area. The pile superintended should have at least 2 years of experience installing these types of piles. Pile installation should be monitored on a full time basis by an experienced geotechnical field engineer. 5.3 SUBGRADE PREPARATION Prior to pacing fill in parking and sidewalk areas, the exposed subgrade soils should be proofrolled with a minimum of two passes of fully loaded dump truck, scraper, or front- end loader. Proofrolling should be performed under the full-time observation and guidance of a representative of the geotechnical engineer. Any areas that are identified as being soft or yielding during proofrolling should be over-excavated to a firm and unyielding subgrade or to the depth determined by the geotechnical engineer. Based on our observation of the existing subgrade soils, we do not anticipate that significant over-excavation will be required. 6.0 LIMITATIONS Recommendations contained in this report are based on the field explorations and our understanding of the proposed project. The investigation was performed using a mutually agreed upon scope of services. It is our opinion that this study was a cost- effective method to explore the subject site and evaluate the potential geotechnical concerns. The soil data used in the preparation of this report were obtained from exploratory borings completed for this study. If the conditions encountered in these locations are different than what was previously encountered at the site, we will make any necessary revisions to our recommendations. It is possible that variations in soil and groundwater conditions exist between the points explored. The nature and extent of these variations 66677/SEA6R049.doc Page 23 of 24 March 1, 2006 Copyright 2006 Kleinfelder, Inc. i may not be evident until construction occurs. If soil or groundwater conditions are encountered at this site that are different from those described in this report, our firm, and the design team, should be immediately notified so that we may make any necessary revisions to our recommendations. In addition, if the scope of the proposed project, locations of facilities, or design loads change from the descriptions given in this report, our firm, and the design team, should be notified. The scope of our services does not include services related to construction safety precautions and our recommendations are not intended to direct the contractor's methods, techniques, sequences or procedures, except as specifically described in our report for consideration in design.

Soil samples collected during the field exploration were classified in accordance with ASTM D2487. All samples were sealed in plastic bags to limit moisture loss, labeled, and returned to our laboratory for further examination and testing. The borings were monitored by our field engineer who examined and classified the materials encountered, obtained representative soil samples, and recorded pertinent information including soil sample depths, stratigraphy, soil engineering characteristics, and groundwater occurrence. Upon completion of the borings, the holes were backfilled with Bentonite chips. Soil classifications were made in the field in accordance with the Unified Soil Classification System, presented on Appendix A-1. Sample classifications and other related information was recorded on the boring logs, which are included in this appendix. The stratification lines, shown on the individual logs, represent the approximate boundaries between soil types; actual transitions may be either more gradual or more severe. The conditions depicted are for the date and location indicated only, and it should not necessarily be expected that they are representative of conditions at other locations and times. 66677/SEA6R049.doc Page 1 of 1 March 1, 2006 Copyright 2006 Kleinfelder, Inc.

APPENDIX B GEOTECHNICAL LABORATORY TESTING B.1 GENERAL We conducted laboratory tests on several representative soil samples to better identify the soil classification of the units encountered and to evaluate the material's general physical properties and engineering characteristics. A brief description of the tests performed for this study is provided below. The results of laboratory tests performed on specific samples are provided at the appropriate sample depths on the individual hand auger logs. However, it is important to note that these test results may not accurately represent in-situ soil conditions. All of our recommendations are based on our interpretation of these test results and their use in guiding our engineering judgment. Kleinfelder cannot be responsible for the interpretation of these data by others. In accordance with standard of practice requirements, the soil samples for this project will be retained a period of 6 months following completion of this report, or until the foundation installation is complete, unless we are otherwise directed in writing. B.2 SOIL CLASSIFICATION Our representative visually examined soil samples in the field, at the time they were obtained. They were subsequently packaged and returned to our laboratory where they were reexamined and the original description checked and verified or modified. With the help of information obtained from the other classification tests, described below, the samples were described in general accordance with the Unified Classification System, ASTM Standard D2488. The resulting descriptions are provided at the appropriate locations on the individual boring and test pit logs, located in Appendix A, and are qualitative only. B.3 GRAIN-SIZE DISTRIBUTION Detailed grain-size distribution analysis was conducted in general accordance with ASTM Standard D422 to determine the grain-size distribution of the on-site soil. The information gained from this analysis allows us to provide a detailed description and classification of the in-place materials. In turn, this information helps us to understand how the in-place materials will react to conditions such as heavy seepage, loading, potential liquefaction, and so forth. 66677iSEA6R049.doc Page 1 of 2 March 1, 2006 Copyright 2006 Kleinfelder, Inc. B.4 MOISTURE CONTENT Moisture content tests were performed to approximately ascertain the in-place moisture content of the soil sample at the time it was collected. The moisture content is determined in general accordance with ASTM Standard D2216. The information obtained assists us by providing qualitative information regarding soil compressibility. The results of these tests are presented at the appropriate sample depths on the boring logs and in this appendix. e66677/SEA6Ro49.doc Page 2 of 2 March 1, 2006 Copyright 2006 Kleinfelder, Inc. _ _ — - -- - _ _— r I� 110.0 - - - I 100.0 -- - - - i 90A - - - , 80A — - -- � ' 70.0 - - - _ _ _ _ oq .� 60.0 - - - - _ � � a. � 50.0 --- -- � ___- -- — _ __ 4 a� a. 40.0 _ 30.0 _ _ _ - - -- 20.0 - - -- - 10.0 - - � i � 0.0 - - - -1 - - � 100.00 10.U0 1.00 O.IU 0.01 Grain Size in Millimeters i - Sa.No. 520-7/35' 2405 140th Ave.NE Sieve Analysis Suite A 101 L04W Loc.
