PROJECT AND SITE CONDITIONS 1.0 INTRODUCTION This report presents the results of our subsurface exploration, geologic hazard, and preliminary geotechnical engineering study for the proposed development at 141XX 57th Avenue S, north of the existing residence at 14112 57th Avenue S, Tukwila, Washington. Preliminary design plans were available at the time this report was prepared, and include the development of a single - family residence on two lots. Our recommendations are based on preliminary, assumed conventional residential loading. Once a final development plan is available, the conclusions and recommendations contained in this report should be reviewed and modified, or verified, as necessary to reflect the project elements. 1.1 Purpose and Scope The purpose of this study was to provide characterization of subsurface soil and shallow ground water to be utilized in the design and development of the subject project. Our study included a review of available geologic literature, excavation of exploration pits, and performing geologic studies to assess the type, thickness, distribution, and physical properties of the subsurface sediments and shallow ground water conditions. Geotechnical engineering studies were also conducted to determine the type of suitable foundation, allowable foundation soil bearing pressures, anticipated settlements, floor support recommendations, and drainage considerations. This report summarizes our current fieldwork and offers development recommendations based on our present understanding of the project. 1.2 Authorization Authorization to proceed with this study was granted by Mr. Lee Stenson of F. Lee Stenson Construction. This report has been prepared for the exclusive use of F. Lee Stenson Construction, and their agents for specific application to this project. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. No other warranty, expressed or implied, is made. 2.0 PROJECT AND SITE DESCRIPTION This report was completed with an understanding of the project based on our discussions with Mr. Lee Stenson. Present plans call for the development of a single - family residence equipped with standard utilities, an attached garage, and a daylight basement. The home will be located August 23, 2001 ASSOCIATED EARTH SCIENCES, INC. MAM /da - KEOI5S4AI'- D: \wp \da \8 -01 - W2K Page 1 141XX 57th Avenue S Tukwila, Washington Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical Engineering Report Project and Site Conditions on a naturally occurring bench on the property at an elevation below the street level. Access to the home will be provided by a driveway constructed of fill soils contained by a retaining wall along the south side of the driveway. The project site is located in Tukwila at a future address of 141XX 57th Avenue S. The project site is bordered along the west by 57th Avenue S, to the north and east by vacant land, and to the south by the existing residence at 14112 57th Avenue S. The project site slopes down gently towards the northeast from 57th Avenue S with a slope of less than 10 percent to the edge of a short slope. This slope increases down at a slope of about 30 percent to a bench area that provides access to the lower portion of the site. The bench area (where the proposed house will be located) is about 70 feet across. The slopes then increase again down toward the northeast toward the northeast property corner. This slope is about 40 percent and continues down to Interurban Avenue and the valley floor of the Duwamish River. The slope to the east property line is heavily vegetated with blackberries and other low growing vegetation. There are other residences located below the lot on the slope to the southeast.. Other on -site vegetation consists of deciduous trees and various shrubs around the existing residence. We understand it was an old orchard for the existing residence, and many of the trees are still present 3.0 SUBSURFACE EXPLORATION Our field study included the excavation of three exploration pits on August 17, 2001 using a small, limited access trackhoe provided by the owner, and a geologic hazard reconnaissance to gain information about the site. The various types of soils, as well as the depths where characteristics of the soils changed, are indicated on the exploration logs presented in the Appendix. The depths indicated- on the logs where conditions changed represent variations between soil types. The locations of our field explorations were determined by approximate measurement from the known site features presented on the site and exploration plan Figure 2. The conclusions and recommendations presented in this report are based on the three exploration pits completed for this study. The number, locations, and depths of the explorations were completed within site and budgetary constraints. Because of the nature of exploratory work below ground, extrapolation of subsurface .conditions between field explorations is necessary. It should be noted that differing subsurface conditions may sometimes be present due to the random nature of deposition. The nature and extent of any variations between the field explorations may not become fully evident until construction. If variations are observed at that time, it may be necessary to re- evaluate specific recommendations in this report and make appropriate changes. August 23, 2001 ASSOCIATED EARTH SCIENCES, INC.

The exploration logs presented in the Appendix are based on the field logs, track hoe operation, and inspection of the sidewalls of the excavation. 4.0 SUBSURFACE CONDITIONS Subsurface conditions at the project site were inferred from the field explorations accomplished for this study, visual reconnaissance of the site, and review of applicable geologic literature. As shown on the field logs, the exploration pits generally encountered stiff, sandy silts underlain by weathered bedrock. The following section presents more detailed subsurface information organized from the shallowest (youngest) to the deepest (oldest) sediments. 4.1 Stratigraphy Fill Fill soil (material not naturally placed) was encountered to a depth of 2.5 feet in exploration pits EP -2 and EP -3. As noted on the exploration logs, the fill generally consisted of loose, dry to damp, tan, silty fine to medium sand with some debris. Since the quality, thickness, and compaction of the fill materials is low or variable, the fill is unsuitable for direct structural support without improvement, as described later in this report. Topsoil Sediments encountered at the surface consisted of forest duff and black, organic, silty sand topsoil. The topsoil generally extended to a depth of 1 foot below the existing grade. This material is unsuitable for structural support. Weathered Bedrock The encountered soils on the site are stratagraphically above the bedrock in the area and are interpreted to be highly weathered andesite. These soils are moist, sandy silts with fragments of the parent rock material. The weathered bedrock graded into more competent andesite at depth in exploration EP -1. This material can provide suitable foundation support for the anticipated loads of residential construction.

The map shows Intrusive bedrock of basalt and andesite. We concur with the mapped sediments. 4.3 Hydrology No ground water seepage was encountered in any of the exploration pits at the time of excavation. If shallow ground water were to occur, we would anticipate it to form a perched layer atop the relatively impermeable bedrock. Seepage could also occur at random depths and locations in the unsupervised or non - uniform fills. The presence or abundance of perched ground water will depend on time of year, amount of precipitation, site development, and off - site usage. On the lot to the southeast, there is an apartment complex with a play area. Near the lot line there appears to be a trench drain along the toe of the slope. This likely indicates that groundwater may occur during certain times of the year, and should be considered when performing the excavation.

GEOLOGIC HAZARDS AND MITIGATION The following discussion of potential geologic hazards is based on the geologic, slope, and ground water conditions as observed and discussed herein. The discussion will be limited to potential seismic, and landsliding or mass wasting hazards. 5.0 SEISMIC HAZARDS AND RECOMMENDED MITIGATION Earthquakes occur in the Puget Lowland with great regularity. The vast majority of these events are small and are usually not felt by people. However, large earthquakes do occur as evidenced by the 1949, 7.2 magnitude event the 1965, 6.5 magnitude event, and the 2001, magnitude 6.8 event. Generally, there are four types of potential geologic hazards associated with large seismic events: 1) surficial ground rupture; 2) seismically induced landslides; 3) liquefaction; and 4) ground motion. The potential for each of these hazards to adversely impact the proposed project is discussed below. 5.1 Surficial Ground Rupture The nearest known fault trace to the project is the Seattle Fault. Recent studies by the U.S. Geological Survey (USGS) (e.g., Johnson et al., 1994, Origin and Evolution of the Seattle Fault and Seattle Basin, Washington, Geology, v. 22, p. 71 -74; and Johnson et al., 1999, Active Tectonics of the Seattle Fault and Central Puget Sound Washington -- Implications for Earthquake Hazards, Geological Society of America Bulletin, July 1999, v. 111, n. 7, p. 1042 -1053) suggest that a northern trace of an east -to- west - trending thrust fault zone (Seattle Fault) may project in the vicinity of Blakely Harbor. The recognition of this fault is relatively new, with the studies still ongoing, and data pertaining to it is limited. According to the USGS studies, the latest movement of this fault was about 1,100 years ago when about 20 feet of surficial displacement took place. This upward displacement (fault trace) can presently be seen in the form of raised, wave -cut beach terraces along Alki Point in West Seattle, and along Restoration Point at the south end of Bainbridge Island. The recurrence interval of movement along this fault system is still unknown, although it is hypothesized to be in excess of several thousand years. Due to the suspected long recurrence interval, the potential for surficial ground rupture is considered to be low during the expected life of the structure.

Page 5 141XX 57th Avenue S Tukwila, Washington Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical Engineering Report Geologic Hazards and Mitigations 5.2 Seismically Induced Landslides Because of the existing gentle slope angles and competence of underlying stratigraphy with no apparent ground water seepage, it is our opinion, that there is a minimal potential risk of seismically induced landslides to occur on the property within the proposed development area. 5.3 Liquefaction The encountered stratigraphy has a low potential for liquefaction due to its dense state, absence of adverse ground water conditions, and the shallow depth to bedrock. 5.4 Ground Motion Based on the site stratigraphy and visual reconnaissance of the site, it is our opinion, that earthquake damage to the proposed structure founded on a suitable bearing strata, and following recommendations presented within this report, likely would be caused by the intensity and acceleration associated with the event. Structural design of the building should follow Uniform Building Code (UBC) standards for Seismic Zone 3 (z =0.3) using soil type SD and take into consideration stress caused by seismically induced earth shaking. 6.0 EROSION HAZARDS Erosion protection and storm water control during development of this site are important so as not to increase the risk of slope instability or allow sediment -laden water to leave the site. Typically, the erosion hazard occurs from the start of the earthmoving process (vegetation removal) until permanent site drainage and erosion protection, usually in the form of vegetation, are established. Therefore, the measures outlined below should be utilized to mitigate this hazard. To mitigate the sheet and rill erosion hazard and potential for off -site sediment transport, the following should be completed during development at this site: 1) Silt fences should be constructed along or below the lower elevation of all disturbed areas and upslope or along any buffer area. This fencing should remain in place until construction and replanting is complete. 2) Soils that are to be used around the site should be stored away from sloping areas and in such a manner as to minimize erosion from the stockpile. Protective measures may include, but are not limited to, covering with plastic August 23, 2001 ASSOCIATED EARTH SCIENCES, INC.

After construction, all remaining exposed soil should be vegetated or otherwise permanently protected from erosion. Control of surface discharge during and following development of the site should be performed in order to reduce the hazard of erosion. Care should be taken to insure that surface runoff and domestic discharge will not be directed onto sloping areas. All devices used to collect surface discharge should be directed into a tightlined system which discharges away from slope areas and into the existing storm water control structures. Uncontrolled discharge on the slope areas may promote erosion and slope instability. S) . Sediment transport from the subject property out onto the local streets may occur during wet weather via delivery truck tires. This type of sediment loss should be controlled by using a quarry rock mat or other coarse, erosion resistant, crushed material surfacing at site access areas.

DESIGN RECOMMENDATIONS 7.0 INTRODUCTION Our explorations indicate that, from a geotechnical standpoint, the parcel is suitable for the proposed development provided the risks discussed are accepted and the recommendations contained herein are properly followed. The foundation bearing stratum is relatively shallow across much of the site and, conventional spread footing foundations may be utilized for support of all structures. 8.0 SITE PREPARATION Based upon the subsurface conditions encountered during exploration, the following site preparation procedures have been developed and include recommendations regarding site drainage, stripping, subgrade protection, proof - rolling, and subgrade compaction. However, the level of site preparation effort is expected to be dependent upon the time of year that construction proceeds. Therefore, bids for site preparation and earthwork should be based upon the time of year that construction will proceed. It is recommended that a representative of our firm observe the soil conditions prior to and during site preparation activities to evaluate the suitability of stripped subgrades prior to placement of structural fill for the driveway and construction of foundation elements and floors. 8.1 Site Drainage and Surface Water Control Adequate temporary and permanent control of surface water runoff and possible subsurface seepage will be required in order to allow for site access and grading for construction of the new home, and installation of underground utilities. Excavation, filling, subgrade and grade preparation should be performed in a manner and sequence that will provide controlled drainage at all times and proper control of erosion. Surface water should be collected and pumped or drained to provide a suitable working platform. Absolutely no surface water may discharge over the slope to the east. The site should be graded to prevent water from ponding in construction areas and /or flowing into excavations. Exposed grades should be crowned, sloped, and smooth -drum rolled at the end of each day to facilitate drainage. Accumulated water must be removed from subgrades and work areas immediately prior to performing further work in the area. Equipment access may be limited and the amount of on site soil rendered unfit for use as structural fill may be greatly increased if drainage efforts are not accomplished in a timely sequence. If a working August 23, 2001 ASSOCIATED EARTH SCIENCES, INC. MAM/da - KE01554A! - D: \wp\da \8 -01 - W2K Page 8 141XX 57th Avenue S Tukwila, Washington Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical Engineering Report Design Recommendations drainage system is not utilized, project delays and increased costs could be incurred due to the greater quantities of wet and unsuitable fill or poor access and unstable conditions. Final exterior grades should promote free and positive drainage away from all structures and the eastern slope at all times. Water must not be allowed to pond or to collect adjacent to foundations or within immediate building areas. It is recommended that a gradient of at least 3 percent for a minimum distance of 10 feet from building perimeters be provided, except in paved locations. In paved locations, a minimum gradient of 1 percent should be provided unless provisions are included for collection and disposal of surface water adjacent to the structure. 8.2 Subgrade Protection Site soils consist predominately of silty fine -to- medium sands and are considered to be moisture- and disturbance- sensitive. These soils will become unstable if disturbed by construction equipment while at elevated moisture contents, requiring additional soil removal. Therefore, in addition to the recommendations presented in the Site Drainage and Surface Water Control section of this report, site preparation and initial construction activities should be planned to minimize disturbance to the existing ground surface particularly during extended wet weather periods. Construction traffic should be restricted to specific drive areas to limit the area where disturbance of the subgrade will occur. If site stripping and grading activities are performed during extended dry weather periods, extensive subgrade stabilization is not expected to be necessary. However, intermittent wet weather periods during the summer months could delay earthwork if soil moisture conditions become elevated above the optimum moisture content. The use of a working surface of crushed rock, or quarry spalls may be required to protect the fine- grained, silty sand soils, particularly in areas supporting concentrated equipment traffic. 8.3 Cut Slope Recommendations In our opinion, stable construction slopes are the responsibility of the contractor, and adequate temporary slope inclinations should be determined during construction. For estimating purposes, we anticipate that temporary, unsupported cut slopes in the medium dense, natural sediments can be made at a maximum slope of 1H: 1V (Horizontal: Vertical), in accordance with WISHA regulations for Type B soils. As is typical with earthwork operations, some sloughing and raveling may occur, and cut slopes may have to be adjusted in the field. In addition, WISHA /OSHA regulations should be followed at all times. August 23, 2001 MAM /da - KE01554A1 - D: \wp \da \8-01 - W2K ASSOCIATED EARTH SCIENCES, INC. Page 9 141XX 57th Avenue S • Tukwila, Washington Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical Engineering Report Design Recommendations 8.4 Setbacks It is our understanding that the proposed home will be set back from the top of the steeper lower slope about 20 feet at the closest point. If. this is the case, no further setback requirements are needed. Should the new construction be located closer than 20 feet to the top of the slope, Associated Earth Sciences, Inc. (AESI) should review and modify this recommendation as necessary. 9.0 STRUCTURAL FILL Structural fill will be used to establish desired grades in the driveway area from the street down to the garage entrance. However, no fill will be placed east of the proposed residence. All references to structural fill in this report refer to subgrade preparation, fill type, placement, and compaction of materials as discussed in this section. If a percentage of compaction is specified under another section of this report, the value given in that section should be used. After overexcavation/stripping has been performed to the satisfaction of the geotechnical engineer, the upper 12 inches of exposed ground should be recompacted to at least 90 percent of the modified Proctor maximum density using ASTM: D 1557 as the standard. If the subgrade contains too much moisture, adequate recompaction may be difficult or impossible to obtain and should probably not be attempted. In lieu of recompaction, the area to receive fill should be blanketed with washed rock or quarry spalls to act as a capillary break between the new fill and the wet subgrade. Where the exposed ground remains soft and further overexcavation is impractical, placement of an engineering stabilization fabric may be necessary to prevent contamination of the free - draining layer by silt migration from below. After the recompacted, exposed ground is tested and approved, or a free - draining rock course is laid, structural fill may be placed to attain desired grades. Structural fill is defined as non- organic soil, acceptable to the geotechnical engineer, placed in maximum 8 -inch loose lifts with each lift being compacted to at least 95 percent of the modified Proctor maximum density using ASTM: D 1557 as the standard. In the case of driveway and utility trench filling, the backfill should be placed and compacted in accordance with current local or county codes and standards. The top of the compacted fill should extend horizontally outward a minimum distance of 3 feet beyond the location of the perimeter footings or roadway edge before sloping down at a maximum inclination of 2H: 11/. August 23, 2001 MAM /da - KE01554A1 - D:\wp\da\8 -01 - W2K ASSOCIATED EARTH SCIENCES, INC. Page 10 141XX 57th Avenue S Tukwila, Washington • • Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical Engineering Report Design Recommendations For fill placed on slopes steeper than 5H:1V, the base of the fill should be tied to firm, stable subsoil by appropriate keying and benching whose dimensions would be established in the field to suit the particular soil conditions at the time of grading. The keyway will act as a shear key to embed the toe of the new fill into the existing slope.. Generally, the keyway for hillside fills should be at least 4 feet wide. Level benches are then cut •horizontally across the hill, following the contours of the slope. No specific width is required for the benches, although they are usually a few feet wider than the dozer being used to cut them. The contractor should note that any proposed fill soils must be evaluated by AESI prior to their use in fills. This would require that we have a sample of the material 48 hours in advance of filling activities to perform a Proctor test and determine its field compaction standard. Soils in which the amount of fine- grained material (smaller than No. 200 sieve) is greater than approximately 5 percent (measured on the minus No. 4 sieve size) should be considered moisture- sensitive. Use of moisture- sensitive soil in structural fills or as utility trench backfill should be limited to favorable dry weather conditions. On -site soils may be used as structural fill and utility trench backfill, provided they are placed and compacted at a moisture content that allows for the minimum specified compaction. If earthwork proceeds during or shortly after rainy periods, some drying of wet soils should be anticipated prior to their compaction. In addition, construction equipment traversing the site when the soils are wet can cause considerable disturbance. If fill is placed during wet weather or if proper compaction cannot be obtained, a select import material consisting of a clean, free - draining gravel and /or sand should be used. Free - draining fill consists of non - organic soil with the amount of fine- grained material limited to 5 percent by weight when measured on the minus No. 4 sieve fraction. A representative from our firm should inspect the stripped subgrade and be present during placement of structural fill to observe the work and perform a representative number of in- place density tests. In this way, the adequacy of the earthwork may be evaluated as filling progresses and problem areas may be corrected at that time. It is important to understand that taking random compaction tests on a part-time basis will not assure uniformity or acceptable performance of a fill. As such, we are available to aid the owner in developing a suitable monitoring and testing program. 10.0 FOUNDATIONS Spread footings may be used for building support when founded on the natural, medium dense, silty sands, or dense to very dense weathered bedrock. We recommend that a maximum allowable soil bearing pressure of 2,500 pounds per square foot (psf) be utilized for design purposes, including both dead and live loads. An increase of one -third may be used for short- term wind or seismic loadings. Perimeter footings should be buried at least; 18 inches below final exterior grade for frost protection; interior footings require only 12 inches of burial. August 23, 2001 ASSOCIATED EARTH SCIENCES, INC. MAM /da - KEO1S54A1 - D: \wp \da \8 -01 - W2K Page 11 14IXX 57th Avenue S Tukwila, Washington • Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical Engineering Report Design Recommendations However, all footings must penetrate to the prescribed bearing stratum and no footing should be founded on or above loose soil, organic soil, or uncompacted fill soils. All footings should have a minimum width of 18 inches. It should be noted that the area bound by lines extending downward at 1H: 1V from any footing must not intersect another footing or intersect a filled area which has not been compacted to at least 95 percent of ASTM: D 1557. In addition, a 1.5H: 1V line extending down from any footing must not daylight because sloughing or raveling may eventually undermine the footing. Thus, footings should not be placed near the edge of steps or cuts in the foundation - bearing soils. Anticipated settlement of footings founded on the native bearing soils or approved structural fill should be less than 3/4 inch. However, disturbed soil not removed from the footing excavations prior to footing concrete placement could result in increased foundation settlements. We recommend that all footing excavations be observed by AESI prior to placing the footing concrete, to verify that the design bearing capacity of the soils has been attained and that construction conforms to the recommendations contained in this report. The governing municipality may require such inspections. Perimeter footing drains should be provided as discussed under the section on Drainage Considerations. 11.0 LATERAL WALL PRESSURES All backfill behind basement walls or around foundation units should be placed as per our recommendations for structural fill and as described in this section of the report. Horizontally backfilled walls that are free to yield laterally at least 0.1 percent of their height may be designed using an equivalent fluid equal to 35 pounds per cubic foot (pcf). Fully restrained, horizontally backfilled, rigid walls that cannot yield should be designed for an equivalent fluid of 50 pcf. Within the driveway area where traffic loads will be adjacent to the wall, a surcharge equivalent to 2 feet of soil should be added to the wall height in determining lateral design forces. It is imperative that proper drainage be provided so that hydrostatic pressures do not develop against the wall. This would involve installation of a minimum 1 -foot wide blanket drain for the full wall height to within 24 inches of final grade using imported, washed gravel against the walls. August 23, 2001 ASSOCIATED EARTH SCIENCES, INC. MAM /da - KE01554A1 - D: \wp\da \8 -01 - W2K Page 12 141XX 57th Avenue S Tukwila, Washington • • Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical Engineering Report Design Recommendations The lateral pressures presented above are based on the conditions of a uniform backfill consisting of on -site, sand compacted to 90 percent of ASTM:D 1557. A higher degree of compaction is not recommended, as this will increase the pressure acting on the wall. Surcharges from adjacent footings, heavy construction* equipment, or sloping ground must be added to the above values. Perimeter footing drains should be provided for all basement walls as discussed under the section on Drainage Considerations. 11.1 Passive Resistance and Friction Factors Basement wall footings /keyways cast directly against undisturbed, dense soils in a trench may be designed for passive resistance against lateral translation using an equivalent fluid equal to 300 pcf. The passive equivalent fluid pressure diagram begins at the top of the footing; however, total lateral resistance should be summed only over the depth of the actual key (truncated triangular diagram). This value applies only to footings /keyways where concrete is placed directly against the trench sidewalls without the use of forms. If footings are placed on grade and then backfilled, the top of the compacted backfill must be horizontal and extend outward from the footing for a minimum lateral distance equal to three times the height of the backfill, before tapering down to grade. The friction coefficient for footings cast directly on undisturbed, dense soils or rock may be taken as 0.35. Since it will be difficult to excavate these soils without disturbance, the soil under the footings must be recompacted to at least 95 percent of the above - mentioned standard for this value to apply. 12.0 FLOOR SUPPORT Slab -on -grade floors for structures may be placed over structural fill or natural, medium dense to very dense sediments after compacting the upper foot of soil to a minimum of 90 percent of ASTM:D 1557. A polyethylene plastic vapor barrier and a capillary break layer consisting of 4 inches of washed pea gravel should be used under the floors. Based on the American Concrete Institutes (ACI) criteria, we recommend placing a 2- to 3 -inch layer of clean sand over the vapor barrier to protect the vapor barrier from construction punctures, and to allow necessary moisture loss through the bottom of the slab to reduce concrete warping during curing.

MAM /da - KE01554A1 - D:\wp\da\8 -01 - W2K Page 13 141XX 57th Avenue S Tukwila, Washington • • Subsurface Exploration, Geologic Hazard, and Preliminary Geotechnical Engineering Report Design Recommendations 13.0 DRAINAGE CONSIDERATIONS All perimeter foundation walls should be provided with a drain at the footing base elevation. Drains should consist of rigid, perforated, PVC pipe surrounded by washed pea gravel. The level of the perforations in the pipe should be set approximately 2 inches below the bottom of the footing at all locations and the drains should be constructed with sufficient gradient to allow gravity discharge away from the building. Roof and surface runoff must not discharge into the footing drain system but should be handled by a separate, rigid, tightline drain. In planning, exterior grades adjacent to walls, except for the east side, should be sloped downward away from the structures to achieve surface drainage. Along the east side, the grades should be adjusted to drain away from the house and away from the top of the slope. It is imperative that no runoff be allowed to discharge over the eastern slope. 14.0 PROJECT DESIGN AND CONSTRUCTION MONITORING At the time of this report, site grading, structural plans, and construction methods have not been finalized and our recommendations are preliminary. We are available to provide additional geotechnical consultation as the project design develops and possibly changes from that upon which this report is based. We recommend that AESI perform a geotechnical review of the plans prior to final design completion. In this way, our earthwork and geotechnical recommendations may be properly interpreted and implemented in the design. This plan review is beyond the current, approved scope of work and budget. We are also available to provide geotechnical engineering and monitoring services during construction. The integrity of the foundation depends on proper site preparation and construction procedures. In addition, engineering decisions may have to be made in the field in the event that variations in subsurface conditions become apparent. Construction monitoring services are not a part of this current scope of work. The implementation of the geologic and geotechnical recommendations contained in this report must be confirmed at the time of construction by AESI to verify compliance with this report. We would be pleased to prepare a cost proposal for these services. August 23, 2001 MAM /da - KE01554A1 - D: \wp \da \8 -01 - W2K ASSOCIATED EARTH SCIENCES, INC.

The report must SPECIFICALLY include: • Soils and construction recommendations for the roadway fill, • Discussion and recommendations for the retaining wall, • Discussion of and recommendations for the house locations and foundations, • Drainage recommendations, • Erosion and sediment control recommendations Please check with building to see if the reviewer wishes to add more to the list. Projects /SFR/Stenson /57th ave s /E01 -023 comm 1 2 • City of Tukwila • PUBLIC WORKS DEPARTMENT 206 - 433 -0179 GEOTECHNICAL REPORT GUIDELINES Applicant Handout Geotechnical reports help determine if the proposed use for a site is appropriate. The report can range from a short site analysis for a single - family residence to a large report for a new commercial building. A geotechnical report contains information used to design retaining walls, foundations, hazardous waste facilities, riverbank stabilization, and infiltration systems, such as trench drains, sand filters and septic drain fields. Geotechnical reports also supply information for settlement analysis and stormwater design. The City requires geotechnical reports for the following: • Projects in the sensitive area overlay • Coal mine Hazard Area (Classes 3 -4) • Riverbank Stability • Hazardous Waste Facility Design • Retaining walls over 4 feet high and • Land Altering , all land altering activities except the following: a. Cut less than 5' and less than 50 cubic yards b. Fill less than 3' and less than 50 cubic yards c. Stockpiling less than 50 cubic yards d. Less than 6000 cubic feet of clearing or impervious surface e. Emergency work f. Public Works improvement projects g. Agriculture h. Certain "grandfather" activities (TMC 16.54) In addition to the above cases, the City may request a geotechnical report when the project or site conditions warrant. Page 1 of 3 •OTECHNICAL REPORT GUIDELIN• Applicant Handout General Requirements A geotechnical report must be prepared and signed by a Washington state licensed geotechnical engineer and must include a site plan which shows all significant surface features. Public Works defines a geotechnical engineer as a professional civil engineer, who has at least four years of professional employment as a geotechnical engineer and has experience in landslide evaluation. Except for infiltration system design, all soil characteristics and classifications shall be per ASTM standards. Soil descriptions shall include erodability, liquefaction, expandability and bearing strength. The logs shall show the date, hole or pit number, elevations for each log relative to the same datum, ground water elevation, soil description, soil classification and for bores, shall include the blow count. For infiltration system design, the report shall identify the limits of any outwash type soils (USDA soil texture classes ranging from coarse sand and cobbles to medium sand). If there are outwash soils onsite, the report shall contain at least one soils log, minimum 4' deep from proposed grade, identify the soil SCS series, the USDA textural class and note any evidence, such as mottling, of a high groundwater table. Limited Geotechnical Report Usually required for single family residential and always required for Class 2 Sensitive Areas. Test pits or hand bores are often sufficient for subsurface investigation at this level. This level investigation shall include at least a description of the existing site surface conditions including drainage, vegetation, slopes and possible effects the project will have on adjoining properties. At a minimum, the report shall include conclusions and recommendations for erosion prevention, construction methods and construction monitoring. Full Geotechnical Report The City requires a full geotechnical investigation for projects which involve any of the following activities. The City may require this level of investigation for other projects depending on site conditions.: • Land altering, exemptions listed in TMC 16.54, • Sensitive areas, classes 3 and 4, • Coal mine hazard areas, • Riverbank stability analysis • Hazardous Waste Facility Design • Retaining wall over 4' high Page2of3 Approved 05.30.00 •OTECHNICAL REPORT GUIDELINE• Applicant Handout At a minimum a full geotechnical report shall include: • a project description, • a site plan showing the bore or test pit locations as steep slopes, drainage and wetlands, • bore logs and soil profiles, • conclusions which include a discussion whether appropriate for the site, • design recommendations, • construction recommendations and • monitoring recommendations. and sensitive areas such the proposed project is At a minimum, the report shall discuss all of the following which apply to the site: • Potential effects on and near the site • Surface and subsurface conditions • Drainage • Erosion • Slope stability • Excavation /fill • Settlement /preload /risk analysis, including monetary liability • Slope stability • Retaining walls /piles /subgrade walls • Pavement References TMC 16.54, 18.06, 18.45, 18.46, 18.104, and 21.04 Uniform Building Code Chapter 18 King County Surface Water Design Manual, 1988, Chapters 3.2.2, 5.1.1, and 5.4 Page 3 of 3 Approved 05.30.00 01/17/01 Permit Package Index 14112 57th S ( 1.)

UKWILr UEN r r ATT: City of Tukwila The following proposal uses the existing lots with an easement access to give the existing house an off street barking area to the rear, allow fire equipment access to front and rear of the new home sites and allow rear access for vehicular traffic and parking. We will be accessing a maximum of 5 building sites with the following site descriptions. BUILDING SITE 41 Lot 3 Lot 3 is an existing lot with a shed on it that will be removed. It is 55 feet of frontage with a depth of 192 feet making the site 10560 square feet. This site has the option of entering on 57th Av. South or entering from the rear. BUILDING SITE #2 Lot 4 Lot 4 is 10,560 square feet with an existing house to remain and be renovated. The positioning of the house allows 5 feet of the approximate 10 -ft side yard to Be dedicated to an ingress and egress easement for the other properties. Also the rear 20 feet of the site will be dedicated to access easement. This will leave approximately 8,600 square feet for the site around the existing house. BUILDING SITE #3 Lot This is a vacant lot typical with the others, 55 feet frontage and 192 feet in depth. This lot will loose 15 feet to provide a 20 -ft access along the West Side to the rear and 20 feet across the rear 'leaving a building area of 6980 square feet. BUILDING SITE #4 Lot 6 This site is near the top of a slope. Care and caution must be used on this type of site at all times. This site does. - owever, give us a fairly level spot that we can build a structure on. Again the site is 55 feet frontage and 1 2 in depth. We will grant a 20 -ft access across or near the rear of the site to access lot 7 BUILDING SITE #5 Lot 78 These sites sit on a sloping hillside they will probably be combined to make one site with a home designed especially for sloped sites. Again much care and caution must be used when building on this type of site. Ce Valle 13!5 Rotiingbay Battl Point 1�`, in rd�tl 1� nrowNevlll R - Manitou flinch' .
