If we do not receive the items required in our June 7, 2000 letter on or before January 8, 2001, your Subdivision application will expire and your associated SEPA application must be withdrawn. No additional extensions will be granted to your Subdivision application. As you have been advised, any public street providing access through the site must be 100% dedicated to the City of Tukwila. Your current proposal for a cul -de -sac is not acceptable as it is dependent upon an easement across land owned by Seattle City Light. You have indicated that given this access problem, your engineer may submit an alternative proposal. If your existing proposal is reconfigured to create 9 or fewer lots, you must re -apply as the proposal can no longer be processed as a subdivision. Additionally, if your proposal for 10 or more lots contains significant revisions or alterations you may have to re- apply.

I would like to ask you for an extension for 120 more days so that I would have more time to work on the right of way easement with Seattle City Light. I understand that it is a very big challenge to get the dedication of the right of way to the City of Tukwila. If my negotiation with Seattle City Light is not very productive in the days ahead, I may need to work with my engineer to re- configure the lots so as to avoid the need of an access easement with Seattle City Light.

CONVEYANCE CALCULATIONS • i • I> TIR Section I Project Overview Site Location The proposed project is to construct 12 residential homes and adjoining access roadways on approximately 2.94 acres on lots 165 and 166, of C.D. Hillman's Meadow Gardens Addition to the City of Seattle. The proposed property is situated immediately east of Interstate 5 freeway ' _ ~ Z right of way and north of the City of Seattle Transmission Line right of way within the City of Tukwila. The property is situated within the 116th Street Drainage Basin. See Appendix A for v site location. o u) w= The storm drainage analysis software utilized is Waterworks hydrology program, using the SCS -' I- Hydrograph methodology in conjunction with the King County Surface Water Design Manual. w 0 TIR Section II Preliminary Conditions Summary u a Soil _ zL.- The properties for this project consist of Type C Hydrologic Soil Group. The soil characteristics w O for the project is determined using King County Soil map of Seattle and Vicinity. Copies of the _. 1973 King County Soils Survey correlated on the 1962 USGS map are attached for reference in 8 Appendix B. o F- LU w. U u. O. LLiz. UN O TIR Section III Off -Site Analysis Upstream Drainage System The topography indicates north -south valley along 47`'' Ave. with a ridge line to the west. • This ridge line rises to its highest ground approximately to the easterly portion of tracts 165 and 166, with its easterly slopes reaching to another southwesterly valley. The drainage from adjacent properties on the east slopes sheet flow along 47`x' Ave. to the unnamed stream. The drainage sheet flows on the southwesterly slopes discharges to a wetland situated to the west line of the tracts along SR 900. The site occupies a forested area sloping 30% towards the east and southwest. The existing ground cover is primary large trees and heavy underbrush throughout the properties. Downstream Drainage System The existing runoff from the east slopes of this property and the upstream contributory area is collected by ditches along 47th Ave. The water is then conveyed by a 36 -inch reinforced concrete pipe line under SR 5 and discharged into a wetland area west of SR 5. The existing. runoff from . the southwesterly slopes discharges into a wetland along SR 900. The water is then conveyed by a 30 -inch reinforced concrete pipe line that connects to the 36 -inch reinforced concrete pipe line under SR 5 that connects to the 48 -inch 116`x' Street Outfall. The 116`h Street Outfall discharges directly into the Duwamish River. Z TIR Section IV Retention/Detention Analysis and Design Part A. Existing Conditions The site occupies a forested area sloping 30% towards east and southwest. The existing ground cover is primarily large trees and heavy underbrush throughout the property. 47`h Ave. S is strip paved as far south as S 109th St., from there it is a narrow gravel roadway as far south as the transmission lines, ending in small turnaround area. The runoff from the property and the adjacent property sheet flow until collected in a ditch line leading to an existing wetland and existing 36 -inch pipe line under SR 5. See computer output for acreage, time of concentration and curve numbers used to determine existing offsite and onsite flow characteristics. Part B. Developed condition A total of 12 residential homes will be constructed on these two lots, resulting in approximately 40.5% of the site being covered with impervious surfaces. Houses, driveways and paved access road encompassing 16800, 3888 and 31178 SF respectively. Approximately 1600 SF of each residential lot will be lawn and shrub. The remainder of the lots will not be disturbed. Since the project is located in the 116`h Street Drainage Basin, a detention pond must be constructed to control the additional runoff. The site is divided in to two drainage areas. Drainage Site aa: This site encompasses a total of approximately 79900 SF. The total impervious area is roughly 31368 SF and the total lawn and shrub area will be 16000 SF. The remainder area is about 32532 SF and will not be disturbed. The peak runoff for 10 year developed condition will be 0.472 cfs. This poses an increase of 0.449 cfs from the existing 10 years conditions. Detention is provided for the resulting runoff increase based on the requirements for King County Manual. The roof top runoff will be conveyed through a downspout collector and a 12 -inch storm sewer pipe to the detention basin. Similarly, all additional runoff will be collected through catch basin along curb and gutter and conveyed to the detention basin. The existing off site runoff will follow the same drainage course to the catch basin via existing ditch. A 12- inch storm sewer pipe will convey the water to bypass the detention system. Drainage Site bb: This site encompasses a total of 35143 SF. The total impervious area is approximately 19591 SF and the lawn and shrub area totals to be 3200 SF. The undisturbed area is roughly 12352 SF. The 10 year peak runoff for developed condition will be 0.315 cfs. This is an increase of 0.268 cfs over the 10 year existing condition. Therefore, detention will be provided based on the King 2 County Surface Water Manual. The roof top ntnoff will be conveyed through downspout collector the onsite runoff and the 47`'' St. runoff will be conveyed through stonn sewer pipe to the detention 'system. All of the offsite runoff will be collected in the ditch along the west side of 47`x' St. and conveyed to the unnamed stream via new culvert. z ,1 Part C. Detention Facility , ,i- iz. re Detention design criteria is based on the King County 'requirements. An underground pipe arch —1 v with a span off 117 -inch and a rise of 79 -inch and a length of 112 ft was designed to detain the u) 0 difference between 10 years existing and 10 years developed condition for drainage site aa. w = in CO u_ Similarly, an underground pipe with a 60 -inch diam. and a length of 200 ft was designed to w 0 detain the difference between 10 years existing and 10 years developed condition for drainage site bb. IL = co D d Detention basins will detain the additional runoff and release it via orifices at the rate of 50% of Z = existing 2 years for 2 years developed condition, 100 % of existing 10 years for 10 years 1--. o developed condition. The 100 % of existing 100 years will be released via a riser. Based on w E' these design criteria, downstream discharge will be reduced to less then the existing condition. 2 o See attached Appendix C. o LS o 1- Part D. Water Quality Facility = W H U Water quality will be provided through the use of "The Stormceptor System ". The design Water tj z. co Quality storm used was 64% of the 2 year / 24 hour or 6 -month event from the developed U H =: condition. 0 F--` The system will be installed downstream of the detention facility. See attached Appendix D. TIR Section V Conveyance System Analysis and Design Ditch and Storm Sewer Design The drainage basin aa offsite flow will be collected by existing V shaped interceptor ditch lines and conveyed to a catch basin the north side of the cul -du -sac and from there via storm sewer pipe to bypass the detention system. All of drainage basin bb the offsite flow will be collected by V shaped interceptor ditch lines along the west side of 47th St. and conveyed to the unnamed stream via new culvert. See attached Appendix E. 3 z Design Frequency 25 year Storm for Culvert with 100 year conveyance. 25 year Storm for Ditch with 100 year conveyance. 25 year Storm for Storm Sewer Pipe. Design References King County Surface Water Design Manual Conclusion Based on this proposed design, in conformance with the King County Surface Water Design Manual, the total peak discharge to downstream will not increase as a result of this project; and this project will not adversely impact the existing downstream drainage system. 4 i z cc J U': 'o O. .,:cow: W =; J W Ol 1,- I-- O' • • •Z1 W W .i:0 co; 0 :W W' F=- U' W ~Q< z ,LLlfn�.

Additional information may be needed. Other requirements /regulations may need to be met. ENVIRONMENTAL 1) The site has slope areas that are 20 percent or greater in gradient. Undeveloped slopes that are 20 percent and greater are generally considered as sensitive areas and subject to the Sensitive Areas Ordinance (SAO). Areas of Potential Geologic Instability are addressed in the Ordinance which is Section 18.45.080 E. of the Tukwila Municipal Code (TMC). The applicant will provide a survey to identify sensitive area slopes present on the property. "Unnatural" slopes created from previous legal grading activities can be exempt from the requirements of the SAO. In addition, a geotechnical report will be required for development proposed on sensitive area slopes. Class 2 areas will have at minimum a site evaluation to review available information about the site and a surface reconnaissance. 2) Natural slope areas, 20 percent or greater, that are cleared for development will be subject to the Tree Ordinance (Tree Regulations - TMC Chapter 18.54). A required landscape plan will consist of tree retention and tree planting per the standards of the Ordinance. Tree replacement is required for those greater than 4 inches in diameter at breast height (DBH) except for black cottonwood trees. Only trees present on sensitive area slopes will be subject to the Tree Regulations. 3) A regulated wetland drainage exists directly south of this site (Wetland #15) within the power line corridor. Surface water and/or groundwater may be associated with this site and draining to the property located to the south. The SAO regulates the use of wetland and watercourse areas and requires mitigation for impacts. If any drainage features are present, a wetland investigation, conducted by a qualified person, is necessary to make a determination. If the area is a wetland, restoration or wetland replacement is required. The standards for wetland mitigation include an area replacement ratio of 1.5 to 1.0 (TMC Chapter 18.45.080 C).

U N` 0 z 1.0 INTRODUCTION We performed this geotechnical study, and prepared this preliminary report, in accordance with the request and authorization of Mr. Antonio Cao for the subject properties at 46xx 1111" Place, in the Ryan Hill area, Tukwila, Washington. This study focuses on the physical and mechanical properties of the underlying soils that comprise the subject property and adjoining steep slopes. This report summarizes the findings of our subsurface investigation, and presents our geotechnical conclusions and preliminary recommendations. These are for considerations in the design of a land subdivision, the application process and associated permit reviews for a development of single family homes. 2.0 PURPOSE AND SCOPE The purpose of this study was to determine the foundation soils characteristics and subsurface conditions based on a subsurface exploration, engineering geology and geotechnical engineering studies. These studies are based on observation of the subsurface conditions in test pits and by performing dynamic cone penetration tests (DCPT) and continuous soil sampling in DCPT holes, necessary laboratory testing and geotechnical analyses for the design of the subject residential development project. We developed our scope of work for this project from a review of available geologic literature, information from the utilities construction projects and observations of highway cut slopes in close proximity of this site. The scope of this study is comprised of a subsurface exploration encompassing five test pits, six dynamic cone penetration tests combined with hand driven multistage soil sampling (MSS); and a geologic /geotechnical reconnaissance based on this exploration and a review of existing available data and literature. This geotechnical report summarizes the results of our exploration for foundation soils and subsurface conditions, and other observations during our geotechnical engineering study, and presents our conclusions and preliminary recommendations for the following: • Slope stability; • Minimum setbacks from critical slopes; • Grading; erosion control; temporary and permanent cut and fill slopes; • Shoring design recommendations; • Bearing capacity analysis and maximum safe bearing capacities; • Foundation design parameters; site and foundation drainage; • Subgrade preparation for spread footings and slab -on -grade floors; • Structural fill; • Lateral earth pressures. Ryan Hill Proposed Residential Development 2 3.0 PROJECT AND SITE DESCRIPTION The property encompasses lots 165 and 166, of C.D. Hillman's Meadow Gardens Addition to the City of Seattle, Division No 2, King County Records — situated immediately east of Interstate 5 freeway right of way and north of the City of Seattle Transmission Line right of way within the City limits of Tukwila. The subject tracts are undeveloped; and no structures presently stand within the properties. 47th Ave S is strip paved as far south as S 109`x' St, from which point it is open as a narrow gravel roadway as far south as the transmission lines, ending in small turnaround area. The gravel portion of 47`h Ave S is closed to traffic by a gate at 109`x' Street. The topography is comprised of a north -south valley along 47`1' Ave with a ridge line to the west. This ridgeline rises to its highest grounds approximately to the easterly portions of tracts 165 and 166, with its westerly slopes reaching to another southwesterly valley situated within these tracts and a ridge line to west along the SR 900 and I -5 corridor. The municipal and franchise utility services are expected to extend from 47t Ave. A sanitary sewer lateral will be extended to properties from the westerly side of SR 900. The proposed project consists of 12 to 14 residential homes along the valley slopes, with a street extending to the mid valley area ending in a cul de sac. A structural earth retaining wall is anticipated along a down slope portion of this street along the power lines right of way. The attached Site Map and soil profile sheet, based on a topography survey of the site, shows the test pits and DCPT locations. The logs of test pits and dynamic cone penetration tests conducted as a part of this study are presented in the Soil Data section at the end of this report. 4.0 SOILS EXPLORATION and SUBSURFACE CONDITIONS We visited the site on March 17, 22 and 25, 2000 excavating five test pits on March 22 and performing six dynamic cone penetration tests and multistage sampling in DCPT holes. We located all test sites based on found surveyed control points. These are depicted on the attached Site Map and soil profile sheet. The lot boundaries and topography, as depicted on the Site Map, is based on a survey by our firm completed in February 2000. See also the attached photographs of the site during this exploration effort in the appendix section of this report after the soils data. Test locations were selected after first conducting a geologic reconnaissance to reveal a representative soils profile for characterizing the soil types and subsurface conditions, and to evaluate slope stability and subsurface drainage. Test pits were excavated using a trackhoe capable of excavating to depths of 12 feet. The DCPT locations were selected either adjacent to the test pits for better understanding of soil density changes correlated to the test pit observations; or performed in areas inaccessible by the trackhoe excavator along the slopes. All soil classification and descriptions are in accordance with the Unified Soil Classification System. Correlation of the DCPT results with the standard penetration test in blows per foot is computed for each increment of cone penetration in blows per l Ocm (4- inches). See the DCPT computation charts and test logs for each location. The dynamic cone test specifications are listed in DCPT computation charts. Each location was tested using a 35mm (13/8") diameter lost cone and recording the blow counts for each 10cm penetration, followed by a multistage sampler augured into the DCPT hole. Ryan Hill Proposed Residential Development 3 Our interpretation of the subsurface conditions, based on the above mentioned testing, is depicted on the ground profile diagram across the valley — see the attached Site Map. The site is underlain by bedrock with a mantle of glacial till and glacial drift deposits, approximately 12 to 15 feet deep within the lower valley floor — see the attached engineering geology report for this site dated March 29, 2000 by Donald W. Tubbs, PhD. The soil profile shows two soil horizons primarily distinguished by changes in density, but with little variation in composition. The top strata to depths of 4 feet consist of glacial drift not consolidated by the weight of glaciers, exhibiting seepage where saturated at valley floor; the middle strata from approximately 4 foot to 10 foot depth is glacial till consolidated by the last glacial advance. The bottom stratum, underlain by the bedrock, is an older very dense till well consolidated by several glacial advances. No seepage was encountered in the till zones. The glacial drift consists of a matrix of silt, sand and gravel containing mostly local bedrock originated semi rounded cobbles and boulders, overlain by approximately 2 feet of topsoil and roots. The glacial till has a similar composition but much denser than ice drift deposits, containing sand lenses. Waldron and others', USGS 1962, have mapped this area as sedimentary rocks of middle Eocene age (Td) overlain by younger gravel (Qyg) to the east. The more recent USGS map by Yount and others' describe these soils as Vashon recessional outwash sands (Qvr) underlain by Vashon till deposits (Qvt) unsorted, unstratified mixture of clay, silt, sand and gravel, very stiff and impermeable. 5.0 SLOPE STABILITY Both ridgelines within the property are comprised of weathered sedimentary bedrock, dipping to the east and northeast; and therefore, slope stability is not an issue within this site. The relatively loose glacial drift deposits over weathered bedrock when saturated pose a minor potential for debris slides in steep slope areas. 1Waldron and others, Preliminary Geologic Map of Seattle and Vicinity, Washington, 1962, map I -354. 2Yount, Minard and Dembroff, Geologic Map of Surficial Deposits in the Seattle Quadrangle, 1993 USGS OFR 93 -233 Ryan Hill Proposed Residential Development -4- 6.0 CONCLUSIONS AND RECOMMENDATIONS The following conclusions are preliminary. We anticipate being engaged in preparation of the construction plans and during the foundation and utility excavation operations. This will enable us to supplement, modify and/or provide additional recommendations, which may become necessary. Based on the stratigraphy, engineering characteristics of the soils found on -site, other subsurface information, and our geotechnical and slope stability evaluation, we conclude that the on -site slopes are presently stable, and would remain stable if the proposed construction is conducted in conformance with our recommendations. It is our conclusion that the site is suitable for the proposed development. The following recommendations are to provide design parameters for the preparation of utilities and street construction plans and specifications. 6.1 Temporary Shoring The need for shoring will be limited to utility trenches and foundation excavations. The surface soils to depths 3 to 5 feet are loose and susceptible to seepage occurrences in the valley floor areas. Any temporary excavation walls must be sloped at 1:1 (1 units horizontal to 1 unit vertical), and where the soils are saturated the side slopes shall not exceed 1 %2: 1. A suitable shoring system must be installed otherwise. Any shoring system should be designed to resist a uniform rectangular pressure distribution of 125H (where H is the wall height) plus a 200 psf uniformly distributed surcharge load for transient traffic loading. The passive earth pressure value for the deadblock or slab design is 300 pcf equivalent fluid. A coefficient of base friction of 0.30 (mass concrete poured directly on existing soil) may be used for the reaction support system. These lateral earth pressure values are for the at- failure soil condition. Soil failure is assumed to occur at wall or block deflection of 0.001H. We recommend that any lagging system be designed to resist an active equivalent fluid pressure of 30 pcf for those locations with no backslope, and 60 pcf where the backslope behind the soldier pile wall is at a maximum grade of 2(H):1(V). To resist the active earth pressures a passive earth pressure of 300 pcf equivalent fluid (for horizontal foreslope) may be used in the design. The soil reaction begins at a depth of one and one -half pile diameters (1.5D) below the surface of the native firm bearing soils. The active earth pressures given here are for the at- failure soil condition. 6.2 Erosion Control The site soils are moisture sensitive and susceptible to erosion. An erosion control plan will be necessary. The erosion control plan shall be based on a drainage analysis for site conditions before and during construction. Erosion control measures and procedures shall be in conformance with the City of Tukwila minimum requirements for this project. 6.3 Site Preparation All vegetation, topsoil and loose material should be removed from the roadway or foundation construction area. We recommend against placing any fill on or near the steep slope. All heavy equipment should be kept away from the top of the excavation embankments and the steep slope areas. Ryan Hill Proposed Residential Development 5 We recommend that the site should be graded to direct construction runoff water to a collection point to be discharged to the storm drain system after sediment removal. All permanent cuts shall be sloped at 2(H):1(V) or flatter. We recommend that we be engaged to monitor all construction operations. 6.4 Lateral Forces Retaining walls should be backfilled with a "free draining' granular material which conforms to the specifications presented in the Wall Backfill section below. The top 2 feet of wall backfill may , _ '; consist of on -site soil that is free of organic material and debris. 11— w A continuous drain should be placed along the base of all basement/retaining walls and v 0 permanent shoring walls, and should be tightlined to a suitable drainage outlet. The drain may consist cn of a 6 -inch diameter, rigid, perforated PVC pipe that is bedded and backfilled with at least 12 inches of w = pea gravel. n �' w0 Walls backfilled in accordance with the above recommendations may be designed using the following lateral forces: cn Active earth pressure (fluid equivalent) Z (flexible wall free to deflect 0.001H, 2H:1 V backslope) 60 pcf p zi— Active earth pressure(fluid equivalent) (flexible wall free to deflect 0.001H, no backslope) 30 pcf :o N t. Passive earth pressure (fluid equivalent) v (undisturbed on site loose ice drift) 280 pcf u- z An active earth pressure coefficient (Ka) of 0.45 may be used for calculation of horizontal forces v =. on the wall due to the surcharge. z ~ 6.5 Wall Backfill We recommend that all wall backfill consist of a "free draining" granular soil that conforms to the following gradation: Sieve Size Percent Passing 4 inch 100 #4 25 -75 #200 5.0 max, Based on the fraction passing the #4 sieve Wall backfill should be placed in 12 inch maximum loose lifts, and should be mechanically compacted where it will support structural loads or paving to at least ninety five (95 %) percent of the laboratory determined, ASTM D -1557 maximum dry density value to a minimum 2.5 foot depth. We recommend using lightweight, hand operated equipment when compacting within 4 feet of the walls. Ryan Hill Proposed Residential Development 6 6.6 Slab -on -Grade For the slab -on -grade floors subgrade should consist of the medium dense / medium stiff silty sand or sandy silt. The subgrade shall be compacted uniformly where the soils are loose. If the on site materials are too wet or not suitable for compaction overexcavate to firm soils and replace with suitable material as directed by the geotechnical engineer during construction. The structural fill for this purpose should consist of a granular material which has less than five (5 %) percent of the material passing the #200 sieve, based on the fraction passing the #4 sieve. The fill should be placed on a properly prepared in -place soil subgrade in maximum twelve (12) inch loose lifts, and mechanically compacted to at least 95% of the ASTM D- 1557 -C maximum dry density value. A four (4) inch layer of clean sand, pea gravel or crushed rock having less than five (5) percent material passing the #200 sieve, based on the fraction passing the #4 sieve, should be placed below the slab as a capillary break. For inside the buildings, we recommend placing a vapor barrier between the bottom of the slab and the capillary break material. If desired, one (1) to two (2) inches of clean sand may be placed over the vapor barrier to aid in concrete curing. 6.7 Building and Site Drainage We recommend placing an interceptor subdrain within the valley floor to mitigate the saturation of the roadway subgrade, since the underlying till is quite impermeable. A geotextile encapsulated subdrain with a plastic drainage sheet placed vertically above it will be the most efficient. This drain shall be tightlined to a suitable drainage outlet. The subdrain shall be installed at a depth just above the very dense till. The drain should consist of a six (6) inch diameter, perforated, rigid pipe that is bedded and backfilled with at least twelve (12) inches of pea gravel wrapped in geotextile drainage fabric. The roof downspouts should be tightlined to a suitable drainage outlet separately from the footing drains. The surface drainage shall be directed to a storm drain with a suitable drainage outlet separately from the subdrains and footing drains. No surface water drains should outlet onto the steep slope area. 6.8 Structural Fill The fill should be placed at or slightly below the optimum moisture content. If the moisture content of the material exceeds the optimum, the material will not compact well and will have to be dried or discarded. We recommend that any fill soil that is imported to the site meet the following gradation: Sieve Size Percent Passing 4 inch 100 #4 25 -75 #200 5.0 max, Based on the fraction passing the #4 sieve We recommend that we sample on site soils stockpiled for use as fill, or any imported fill material, prior to placement to conduct necessary laboratory tests. We recommend that all fill be placed on a firm, horizontal subgrade that is free of organic material, standing water, loose soils or debris. The Ryan Hill Proposed Residential Development 7 I • { fill should be placed in horizontal, maximum eight (8) inch loose lifts, and be compacted to at least 95% of the ASTM D 1557 -C maximum dry density value. We recommend that we be engaged to provide continuous inspection and testing of fills to verify proper placement and compaction of structural fills. 7.0 GENERAL We should be engaged to work with you in reviewing the final plans to provide specific and detailed recommendations. We anticipate reviewing the final plans to assure that our recommendations have been properly interpreted and implemented; and we anticipate being engaged to observe the site preparation and earthwork to verify subgrade conditions and confirm bearing soils. These recommendations are for engineering review to be incorporated into the streets, utilities and building design elements. We expect the on -site soil and ground water conditions to reflect our findings; however, variations may occur. Should soil conditions be encountered that are cause for concern, or conditions that are not addressed in this report, AZIZ Engineering NW should be contacted immediately to determine if additional or alternate recommendations might be necessary. This report has been prepared for the exclusive use of Mr. Antonio Cao, for specific application to the proposed Ryan Hill residential development project in Tukwila, in accordance with generally accepted soil and foundation engineering practices. No other warranty is made, expressed or implied. Thank you for using our services. Should you have any questions, please feel free to contact us at any time. Sincerely, AZIZ Engineering NW Inc.

Tubbs subject: Antonio Cao property - Ryan Hill project date: March 29, 2000 At your request, I am providing the following description of geologic conditions at and near property you are investigating, located north of South 111th Street and between 47th Avenue South and Interstate 5 in Seattle, Washington. This description is based on published geologic maps, my observation of surface conditions at and near the site and my observations of several test pits that you excavated and logged on March 22, 2000. I understand that you are investigating subsurface conditions within the property as a basis for developing geotechnical recommendations for residential site development. The site is located along the east valley wall of the Duwamish Valley. The general topography in the vicinity of the site is glacial in origin, having been created by subglacial and deglacial erosion and deposition of bedrock and previous glacial and possibly non - glacial deposits. Immediately north of the property that is the subject of your current investigation two bedrock -cored hills rise about 50 to 75 feet above the adjacent valley wall. These hills are part of a group of similar bedrock -cored hills that exist near the eastern margin of the Duwamish Valley in the vicinity of the site. Though the cores of these hills consist of bedrock, they are generally mantled with glacial drift and are elongated north -to -south with a streamlined shape as a result of being overridden by the Vashon glacier (the most recent glacier to occupy this area - some 15,000 to 13,500 years ago). The glacial ice was more than a half mile thick in the vicinity of the site during the maximum extent of that glaciation. At some point during ice retreat glacial meltwater flowing along the eastern margin of the wasting ice within the Duwamish Valley appears to have been diverted eastward around the two bedrock -cored hills adjacent to the site, and thereby created the recessional meltwater channel which 47th Avenue follows northeast of the site. The bedrock that partly underlies the hills, and which also exists north and south of the site along portions of the east Duwamish Valley wall, consists of sedimentary rock of Eocene (Tertiary) age and is therefore roughly 40 to 50 million years old. The glacial drift that overlies the drift may include some glacial or nonglacial deposits older than the Vashon glaciation, but the materials observed in the test pits consist mostly of a mixture of locally derived bedrock blocks imbedded in a matrix of silty sand with some gravel. This mixture of bedrock and matrix material is a local variation of the widespread (in Seattle) Vashon glacial till, and is dense to very dense as a result of consolidation beneath the glacial ice. The glacial till is locally less dense near its upper surface, perhaps the result of only partial ice - consolidation during the waning stages of the glaciation, and it is Locally overlain by recessional drift that consists of similar materials but which have not been ice - consolidated. 7505 -A West Lake Sammamish Parkway Northeast 1x` +*riA?fr..dza7+�?�re��mnxr.•r Redmond, Washington 98052 425 - 882 -4850 View to Powerline Easement, Excavating Test Pit No 1 Existing Slope and Vegetation • Test Pit No 3, West Valley Side, Interface between Older and Younger Till, see scoring Test Pit No 1, East Valley Side Upper Soil Profile, Test Pit No 1 East Valley Side at Toe of Slope Transition From Younger Till to Older Till, marked with hand shovel, Test Pit No 3 west valley side at toe of slope Cavities from weathered local origin boulders, Test Pet No 1 Seepage at interface between outwash deposits and the top of Younger Till, Test Pit No 2 at valley floor Z W 2 JU 00 0 J I f" WO 2 LL.a co =d I-W Z= I- O ZI- W • W 0 O -.
