FM.ONS CITY OF TUKWILA 6200 SOUTHCENTF_RBOULE_VARD, TUKWILA. WASHINGTON 98188 March 21, 1990 Robert H. Schofield 4212 Hunts Point Road Bellevue, Wa. 98004 RE: Southcenter Retail Building II Dear Bob: PHONE # (206) 433.1800 Gary L. VonDusen, Mayor The Public Works Department has reviewed your plan submittal for subject site (Plan Sheet Nos. C -1 and C -2 of 2) and request resubmittal to address the following comments: 1. On your Utility Permit Application form, check the permits you believe you are requesting. From Public Works initial review of the submitted plans, the following permits appear to be appropriate candidates: Fire Loop /Hydrant, Landscape Irrigation, Sanitary Side Sewer, Water Meter (Permanent), Water Meter (Temporary) ?, Water Meter Exempt ?, Curb Cut /Access /Sidewalk, Channelization /Striping /Signing., Hauling ?, Storm Drain, and Flood Control Zone Permit. 2. On your Utility Permit Application under "monthly service billings to ", check the boxes after "water, sewer, Metro" and "stand -by ". 3. The City has now instituted a new Storm and Surface Water Utility charge. Requested is you identify the demensions of all impervious surfaces, (including rooftops, drive- ways, asphalted areas including parking lots) and also all pervious surfaces including landscaping, and areas of natural vegetation). Next you are requested to provide the percentages of impervious surfaces (in square feet) over the entire lot size (after street mention R/W acquired) along with your storm and surface water billing account number, so that the City may adjust that billing per the modified impervious surfaces on this lot calculation for the proposed development. Please use the attached form to provide your calculation. This shall be part of the Development's site plan submittal. • • 4. Future South 168th extension (to east) and alignment to northerly access to proposed Development: A. Identify schematics for proposed 168th Street (contact Brian Shelton for existing plans and studies for this future alignment. (433- 0179). Brian believes he has given you this information in the past). B. Provide channelization plan of Southcenter Parkway fronting the development 500 feet to the north and south of the development, pre, post and future resignalization and extension of 168th. C. Identify (schematically)future signalization including signal poles, detector loop system and associated handholes /manholes in underground wiring. D. Identify to provide capped conduits for proposed signalization and for future signal interconnects relative to your proposed improvements. E. Identify schedule for South 168th Street and signalization improvements (by others). F. Identify proposed easements to the City for future signal poles /handholds /detector loops and underground conduits including interconnects. Based on schematics, identified in item 4 -C above). G. Locations shall be tied to known momumentation. H. Identify southerly Puget Power access and determine how your access fits in with this existing access. 5. Securing 30 foot right -of -way by the Development: Identify on plan, processes owner will go through after street vacation, including purchase of property from Puget Power. This plan cannot be approved until the owner has secured all properties. 6. Identify on plan submittal prior traffic studies and City determinations, including requirement to provide to the City $38,850, as a condition of the Curb Cut /Access Permit for your pro -rata share of traffic mitigations signed by all property owners involved. Also included in these easements shall be an easement to Puget Power, allowing access through the Development to Puget Power, before permits are issued (Refer to the City Engineer, Ron • • Cameron - 433 - 0179). 7. Curb Cut aprons: change your plan references from "new City Standard R -6" to "new City Standard R -7 for commercial driveways ". 8. Common access easements for north and south access points and internal driveways: Per the requirements of the boundary line adjustment process, the development has been required to provide easements for common access at the southerly joint access and common use of the northerly access and through the properties. These easements shall be submitted as part of this plan review approval and reflect the findings of -the BLA process. 9. Identify WSDOT drainage easement which traverses under proposed Building B. Identify if this easement is still in affect on the plans. Also identify the existing drain provided under the Grade and Fill Permit to accommodate WSDOT drainage system. Per the requirements of the Grade and Fill plan review, up- grade /replace this WSDOT system - identify how this state drainage system is now going to be accommodated. Finally in a letter from WSDOT or yourselves commemorating discussions with WSDOT, identify acceptance with this proposed accommodation to WSDOT drainage by this development. Please note all permanent storm drains shall be constructed to City Standards. 10. Provide a temporary and final erosion control plan showing intermittent contours and final contours during the construction phase. 11. Identify utility easements for joint use drainage, fire loop and other utility infrastructure and provide inter - development agreements between to the two parcels of property for the maintenance, operation, monitoring, repair or replacement of these facilities as part of your plan submittal. 12. On page C -2 of 2, under "note #16 - note! note!..." add "... and Fire Marshall and insurance underwriter." 13. On page C -2 of 2, note #23, identify PVC pipe. 14. Identify any slope easements by WSDOT, (if exist). Provide review and approvals from WSDOT for any construction into the hillside behind I -5, and accommodation of WSDOT drainage from the hillside through your property. 15. The northerly access behind Building A which turns to the south appears too close to the corner of Building A. Review turning radius of emergency vehicles and setbacks of buildings from edge of pavement, per City Standards Templates and Fire Marshall's review. Your traffic engineer shall conduct a triangulation study for sight distance for turning movements around Building A. 16. The City's drain pipe materials standard has changed since Tukwila Retail Phase I Development. The City no longer accepts corrugated metal pipe and requests that all storm drainage identifying corrugated metal pipe be changed to concrete and /or reinforced ADS pipe. 17. Drainage behind Building B: By the placement of this building in such close proximity to the edge of the I -5 bank, sub- surface water may either be blocked or must traverse under the building pad. This water shall be picked -up prior to its migration to the east through an appropriate drain system designed by your Civil Engineer. Questioned are the dash lines which go east and west into the State R /W: do these lines represent drain pipes how are they accommodated? A typical section of your proposed drain system behind your building, needs to be provided on the plans to assure that no surface /sub - surface drainage can impound at the footings or face of Building B. 18. Review the accessability of these buildings with the Fire Marshall, Nick Olivas, 433 -1859. 19. Provide an 18" minimum separation at crossings at all water and sewer systems. Sanitary side sewers and private sanitary sewer mains: Each structure shall have a separate side sewer from the structure to the main (public or private). Your side sewer from Building B exceeds 150 ft. Per the City's Development Standards, side sewers shall be no more than 150 ft. in length. Suggested is a common private sewer main common to Buildings A and B be provided at the juncture of the two side sewers shown on the plans. Required is a manhole structure at the upper reach /juncture of these two side sewers. 21. Provide cleanouts for side sewers every 100 ft. at bends and at the exit point of each structure. 22. On sheet C -1 of 2, bottom center, the note existing sanitary invert 14.0 plus or minus "verify ". This note shall be • revised to indicate (highlight this note), that this stub elevation shall be dug up, field verified by your surveyor and tied into all other buildings and site elevations prior to beginning any site construction overall. 23. Call out the type of pipe for sewer on the plans.. 24. Specify the bedding, backfill, based on your soils engineers report and include conditions which have been found to other engineering studies, (refer to soils engineer studies on file for LID # 32 - Southcenter Parkway Sanitary Sewer Extension). 6k �. It is questioned whether special backfill or special pipe 01 bracing of the sanitary side sewers /private mains will not g Abe necessary to assure that the 2% grade can be maintained in OL'4,62 these pipes to assure no significant sagging of pipes occur. On Plan Sheet 2 of 2, "Note 9 ", check on the calculation for P the soils condition for F type bedding to assure that this is appropriate per the soils reports on file. Provide specific design bedding and backfill based on the soils engineer Study of Record including soils engineers studies and final findings for the construction of LID #32 on file with the City. 25. On plan sheet C -2 of 2, "Note #10" - take out "except as shown` on plan" as there are no exceptions and add "for sewers and water lines ". 26. A southerly access shall be stripped for two lanes only, one ingress and one egress. 27. The City shall determine, based on the traffic studies, whether right turn in and out of the northerly access is appropriate. 28. Per the Ritten house - Zeman and Associates Sub- Surface Exploration and Geotechnical Report (W -6407) (October, 1989) - 4.3.1, identifies pilings (15,500 ft. /# to 26,000 ft. / #). An analysis of rosidum settlement to adjacent utilities and structures shall be provided including the flat sewer main in Southcenter Parkway shall be provided by your soils engineer. Also, a monitoring program and schedule shall be provided (Reference: Prior grade and fill requirements for this development, of Public Works). 29. Per Section 4.5 of the Soils Report, elaborate on WSDOT horizontal drains: their function; current condition; WSDOT access forr maintenance and monitoring; conditions needed be kept to afford stability to I -5 slope; any rehabilitation of WSDOT needed; WSDOT review of your soils report and findings under Section 4.5 and plans. Requested is a resubmittal of these plans, addressing the above comments. Once Public Works Department has received this re- submittal, we will continue with our review process. If you have any questions or I can be of further assistance do not hesitate to call me at 433 -0179. Sincerely, Phil Fraser Senior Engineer Public Works Dept.

I hereby request that you immediately begin all necessary reviews to ensure the timely issuance of a building permit. I acknowledge the following: 1. That this building permit application has been submitted prior to SEPA review, approval by the Tukwila Board of Architectural Review and receipt of the City's fully clarified conditions to the moratorium waiver, 2. That this building permit application is vested only to the extent it is consistent with all the conditions finally established in the reviews listed in Item No. 1. 3. That the above analyses and City actions may require project design changes which may result in additional plan check fees and review time, 4. That the building permit shall not be issued until the proposed project is consistent with all final conditions in Item No. 1, 5. I agree to pay any such fees, and 6. I hold the City harmless for any delays or costs incurred as a result of project design changes due to the above. Sincerely, Robert Schofield cc: Beeler /City Attorney /file.

Schofield 4212 Hunts Point Road Bellevue, WA 98004 RE: Moratorium Waiver and Building Permit Application for Southcenter Retail Building II. Dear Bob, I need you to execute the attached SAO agreement document and mail us an equivalent of the attached letter. The SAO agreement document is necessary to satisfy the Council's conditions to the moratorium waiver. I have attached a large map showing DCD's interpretation of the "no development area" which should serve as Exhibit B in the SAO agreement. This large map must be reduced to 8.5 x 11.5 inch size using a PMT process or equivalent to allow easy recording (photocopier reductions are not acceptable). All originals must be submitted to the City by March 8, 1990. The City will then record all documents with the County and bill you for recording costs. The attached letter is a draft request to process the building permit application before completing all normal review processes. A letter with this substance is required in order to begin permit review. The permit has . already been inserted into the normal building permit review process in anticipation of this letter. A letter must be received prior to February 18th in order to avoid delays. Please contact me at 433 -1858 if I you have any further questions on these matters. Vernon Umetsu, Assoc.

A brief summary of the project geotechnical considerations is presented below: • Our subsurface exploration program consisted of a series of backhoe excavated test pits along the west property margin and western portion of the site supplemented by a series of Dutch cone penetrometer probes. On -site data regarding existing site conditions was supplemented by the results of an adjacent study to the south, our report W -5437. a Subsurface conditions disclosed along the west margin of the proposed building and the test pits were quite variable. Interbedded soft silts and organics were disclosed at the location of test pit TP -1 while test pits TP -4 and TP -5 encountered medium dense, gravelly silty sands near the proposed footing elevation. Extensive deposits of organics, soft material, decomposed wood and other highly compressible materials were disclosed at the location of the other test pits excavated for the project. o Deep explorations, consisting of Dutch cone penetrometer probes generally disclosed interbedded soft clays with organics, loose sand deposits with probe refusal noted generally in the range of 30 to 35 feet below existing site grades. Based on the adjacent explorations we anticipate the deeper native deposits present at depth will likely consist of very stiff to hard silt soils. o Owing to the extensive thickness of compressible deposits and the random distribution of organic soils below the site, significant total and differential settlements should be anticipated associated with the filling of the project site. Based on subsurface conditions encountered, and the variations in thickness of the highly compressible organics and soft materials encountered, we recommend the proposed structures and floor slabs be supported using treated timber pile foundation. The treated timber piles should be driven into the very stiff to hard silt layer located between 25 and 35 feet below existing site grades at the location of our explorations. Mr. Robert H. Schofield 4212 Hunts Point Drive W -6407 Page 2 o It may be possible to support the northernmost portion of the westerly . building using spread foundations. Based on site topography, and the results of our test pit exploration program, it appears that the northern half to one - third of the westerly building line may be supported by spread footings. The transition point from pile to spread footing support in this area could be evaluated in the field once construction begins. This summary is presented for introductory purposes and should be used in conjunction with the full text of this report. The project description, site conditions and our design recommendations are presented subsequently in the text of this report. Exploration procedures and logs are presented in Appendix A. 2.0 PROJECT DESCRIPTION The project site is located on the west side of Southcenter Parkway in Tukwila, Washington. The site is presently occupied by a residence, garage and several small outbuildings. The proposed development will consist of two retail structures with their approximate orientation shown on the Site and Exploration Plan, Figure 1, attached to this report. Site grades will fall from approximately a planned floor grade of 28 feet for the westernmost building and site grades will match that of the adjacent Southcenter Parkway along the east margin of the proposed development. The purpose of this study was to establish general subsurface conditions from the site from which conclusions and recommendations for foundation design and construction could be formulated. Scope of work consisted of the field explorations, geotechnical analyses and report preparation. In the event of any changes in nature, design or location of the structures, the conclusions and recommendations contained in this report should be reviewed and modified, if necessary, to reflect those changes. This report has been prepared for exclusive use of Mr. Bob Schofield, for specific applications to this project in accordance with generally accepted engineering practice. Site conditions were evaluated in October, 1989. The surface and subsurface conditions are described below, while the exploration procedures and detailed interpretative logs of Mr. Robert H. Schofield 4212 Hunts Point Drive W -6407 Page 3 the explorationaccomplished for this study are presented in Appendix A. The approximate locations of the explorations are indicated on the Site and Exploration Plan, Figure 1. 3.0 SURFACE CONDITIONS The project site was actively farmed at the time of our exploration program. The southern portion of the site was cultivated land, while the house, garage and several outbuildings occupied the northern half to two- thirds of the parcel at the time of our site work. Site grades appear to be on the order of 4 feet below the elevation of Southcenter Parkway. Along the west margin of the property site grades were somewhat higher. The drainage ditch crossed the southern third of the parcel and was carried via a culvert to discharge into a ditch along the north property margin. Horizontal drains installed to hillside supporting Interstate 5 were not apparent along west margin of the property except at the extreme south end of the proposed development site. The flow from the horizontal drains were captured and collected and directed off -site southward in flexible hoses to the adjacent storm water collection system for the adjacent development. 3.1 Subsurface Conditions The subsurface conditions vary considerably across the proposed site. Test pits TP -4 and TP -5, which were excavated along the west margin of the north -south trending building, indicated medium dense granular deposits at or near the likely foundation grade. The other test pits and the deep explorations accomplished for this study generally disclosed loose, highly compressible organic materials within the depths explored. The Dutch cone probes generally encountered refusal resistance within a depth of about 35 feet below existing site grades. Based on subsurface conditions disclosed for the adjacent retail parcel to the south, we anticipate the native soils present at depth will likely consist of very stiff to hard silt soils. Detailed descriptive Togs of the explorations accomplished for this study are included in Appendix A, together with a descriptive narrative of the exploration procedures utilized for this study. A number of the test pits and Dutch cone probes indicated the presence at a significant depth of organic clays with distinct organic zones noted at random depths throughout the deposits. Such organic soils, when loaded, undergo significant volume change as manifested by ground surface settlement. The settlement response of the organic Mr. Robert H. Schofield 4212 Hunts Point Drive W -6407 Page 4 deposits occurs in two distinct phases. The initial or primary movement occurs rather rapidly over a period of several months. Longer term settlements, associated with secondary compression of the organic constituents can also be of relatively large magnitude and can extend with decreasing rates of settlement in excess of 20 years. Groundwater, as manifested by seepage into the test pits, was encountered at depths of 3 to 31/2 feet in several test pits. However, near surface materials were mottled in a number of the test pits which indicated intermittent saturation likely associated with seasonal variations in the groundwater conditions. We would anticipate the groundwater would rise to within several feet of the existing site grades during the wetter winter months. It should be noted that groundwater conditions will vary with seasonal changes, changes in site utilization, changes in off -site utilization and other factors. 4.0 CONCLUSIONS AND RECOMMENDATIONS We understand that proposed project is to consist of two retail buildings with the approximate orientation shown on Figure 1. Site grading is proposed to bring the site to the approximate elevation of Southcenter Parkway. We would anticipate significant total and differential movements would be associated with the fill placement. In order to improve the performance of fill supported pavements and utilities we recommend the construction of settlement sensitive utilities and pavements be deferred as long as possible after the initial placement of fill. In general, pile support for the proposed buildings is recommended. Evaluation of alternative spread footing support for the extreme northern portion of the westernmost building should be evaluated at the time of construction. The following sections of this report present our recommendations relative to site preparation, foundation design and construction, and site drainage. 4.1 Site Preparation We recommend the brush, vegetation and trees present along the west margin of the property be stripped and grubbed. The existing residence and outbuildings should be demolished and the debris removed from the project site. The existing utilities, underground tanks, and the septic tank should be removed or abandoned in place in accordance with local codes and practice. Existing foundations, floor slabs, debris should not be disposed of on -site as they could obstruct later pile driving operations. Mr. Robert H. Schofield 4212 Hunts Point Drive W -6407 Page 5 We recommend that the cultivated areas be closely mowed, with vegetation removed prior to fill placement. The near surface site soils which will comprise the site subgrade prior to fill placement will be predominantly silty deposits. These soils are prone to disturbance in wet site conditions. Fill placement across silty soils in wet site conditions may require the placement of an initial thickened lift in order to provide support for construction vehicles. In very wet weather, a working surface of quarry spalls or sand and gravel may be necessary to protect the subgrade and support rubber -tired construction traffic. If the subgrade exposed by stripping or after demolition is more than several percent over optimum moisture content, at the concurrance of the geotechnical engineer, compaction of to the subgrade by prerolling should not be attempted. Rather, the subgrade should be cleaned as much as possible of loose or soft materials and a thickened layer of clean sand, sand and gravel or quarry spalls be placed before compaction is attempted. Due to the anticipated magnitude of settlement it appears advantageous to place fill on the project site as soon as possible. It does not appear that a preload or surcharge, even is extending over a period of several months, would effectively reduce post- construction settlement to allow slab -on -grade support of the proposed buildings. For that reason, it appears a general site filling operation rather than localized fill placement and surcharge in building areas would help to mitigate future settlement distress. Construction of settlement sensitive pavements, structures or utilities should be deferred as long as possible. Steep gradients should be provided for buried gravity utilities where gravity flows are to be maintained. Along the east margin of the property, existing buried utilities if present at conventional burial depths would be underlain by an extensive deposit of very soft to medium stiff clays and organic clays. The settlement response of these deposits will be slow, owing to their low permeability, and should extend over a number of years as organic zones and layers were noted in our explorations. However, the actual magnitude of increased vertical stress in the deposits below the pipes would be small, as it appears that the soils above the pipes presently are generally at or near the grade of Southcenter Parkway. As Mr. Robert H. Schofield 4212 Hunts Point Drive W -6407 Page 6 a gross approximation, the settlement of the pipelines would be roughly equal in inches to the thickness of fill placed above the pipelines in feet. The off -site impacts of fill placement may generally be assumed to extend to a horizontal distance equal to about half the thickness of compressible deposits present below the site. 4.2 Structural Fill All fill under roadways, parking Tots, sidewalks and within the building area for lateral resistance to the piles should be placed in accordance with the following recommendations for structural fill. Prior to placement of structural fill, the ground surface to receive fill should be prepared as previously recommended. Structural fill should be placed in loose lifts not exceeding 8 inches in thickness. Individual lifts should be compacted such that a density of at least 90 percent of the modified Proctor maximum dry density (ASTM:D 1557) is achieved. We recommend that a representative of our firm 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 grading progresses. The suitability of soils used for structural fill depends primarily on the gradation and moisture content of the soil when it is placed. As the amount of fines (that portion passing the U.S. No. 200 sieve) increases, soils become increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult or impossible to achieve. Soils containing more than about 5 percent fines by weight can not be consistently compacted to a firm, non - yielding condition when the moisture content is more than about 2 percent above optimal. Based on the interbedded and highly variable nature of the compressible deposits on -site, it does not appear feasible at this time to preload building pads. In order to improve the long -term performance of fills under parking areas, we recommend that the fill in parking and building areas be placed as soon as possible and the construction of settlement sensitive utilities or pavement structures be deferred until the following construction season. We recommend the upper two feet below pavements and within the building area consist of clean sands and gravel. This recommendation is intended to provide improved subgrade support for parking areas and pavements, and to promote drainage below building areas. The upper 2 feet of fill should consist of a well graded sand and gravel Mr. Robert H. Schofield 4212 Hunts Point Drive W -6407 Page 7 with less than 5 percent fines when measured on the minus No. 4 sieve fraction. It should be recognized that even during the summer, delays in grading may occur due to precipitation. In the upcoming wet weather months, it may be impractical to use silty deposits and attempt to compact those soils unless protracted periods of dry weather occur. If it is not practical to dry back wetted silty soils, it may be necessary to waste them off -site. We would recommend any of the on -site soils not meeting the above specifications for drainage material within building areas be overexcavated, and placed in the deeper portions of site fills below pavements. Soils used for structural fill purposes should have a maximum particle size on the order 6 inches and be free of organics or any other deleterious debris or materials. 4.3 Pile Foundations Due to the depth and compressibility of the organics, peat and soft silts, we recommend that the building and floor slabs be supported on pressure treated timber piles. We recommend that timber piles be driven on the order of 5 to 8 feet into the very stiff to hard silts interpreted to be present at depth below our excavations from approximately 25 to 35 feet below the existing ground surface. For timber piles with 8 inch minimum tip diameter, we recommend a maximum allowable vertical capacity of 20 tons. Timber piles with 10 -inch minimum tip diameter may be loaded to the maximum allowable vertical load of 25 tons. A one -third increase in this value could be used to resist transient seismic or wind loads. These allowable pile capacities have been reduced to account for down drag or negative skin friction. Negative skin friction will develop due to the downward relative movement of the sands and structural fill around the pile as the soils consolidate. We expect pile length range up to about 40 to 45 feet. Some variability in driven lengths should be anticipated, based on the Dutch cone probes. Probe refusal was noted as high as about 22 feet at the location probe P -5 and as deep as about 35 feet at the location of probe P -1. In general, it appears that deeper piles will be required along the north and east sides of the proposed buildings, while the pile lengths for the long, north -south trending building would be somewhat Tess. Mr. Robert H. Schofield 4212 Hunts Point Drive W -6407 Page 8 4.3.1 Pile Installation We recommend that timber piles be driven with a diesel, air, or steam hammer having a rate energy not less than 15,500 foot pounds, and not more than 26,000 foot pounds per blow. In our opinion, a drop hammer would not be appropriate for pile installation at this site. Where piles are placed in groups, we recommend that the pile spacing of no Tess than 3 pile diameters on center be maintained. With large pile groups or clusters, piles should be driven from the center of the pile group outward. During driving, the actual pile capacity should be verified in the field, based upon the use of a dynamic pile driving formula. The piles should be driven until they reach an apparent capacity in excess of their allowable capacity to account for downdrag Toads. 8 -inch tip piles should be driven to an apparent capacity of 25 tons, and 10 -inch tip piles should be driven to an apparent capacity of 30 tons. These apparent capacities include the allowance for the downdrag loads the piles will experience due to the consolidation of the organics and overlying deposits. We recommend that the installation of all piles be observed by a qualified representative from our firm. Our observer would evaluate the contractor's operation as well as collect and interpret the pile installation data. Due to variations in the density and gradation of the bearing horizon, the test pile driving program could be used to evaluate the pile driving characteristics of the site and to allow a closer determination of pile order length. 4.3.2 Lateral Loads Lateral loads imposed on the building may be resisted by passive pressure applied against the embedded portion of grade beams, pile caps and piling. We recommend an allowable passive earth pressure, expressed in the form of an equivalent fluid unit weight, of 200 pounds per cubic foot. This pressure may be applied over an area of 2 pile diameters to a depth of 6 feet. If grade beams or pile caps are embedded in structural fill, we recommend the passive pressure be utilized in design discounting the upper 1 foot to account for possible settlement in the underlying soils. Frictional resistance below grade beams or floor slabs should not be assumed. These above pressures include a minimum factor of 1.5 which is considered appropriate for the transient nature of horizontal Toads applied. Mr. Robert H. Schofield 4212 Hunts Point Drive W -6407 Page 9 4.5 Drainage Considerations During the initial construction activities along the west property margin, we recommend surface water be intercepted and directed off -site to an appropriate discharge. We recommend the buildings be underlain by at least 2 feet of clean, free draining materials in order to promote drainage. In lieu of a conventional footing drain at the footing or pile cap invert elevation, we recommend the building perimeter be protected from moisture through the installation of a deepened footing or perimeter drain extending at least 3 feet below the surrounding finish grade. If soft or wet areas with spring activity, or at the location of existing horizontal drains emanating from the 1 -5 embankment to the west, those areas should be blanketed with rock or the drain's flow should be collected via tightline and directed to an appropriate discharge point. Prior to construction, all sources of surface water should be routed away from construction and building areas as much as possible. Site grades should be planned to slope away from the building. Roof and surface run -off should not discharge into the footing drain system. Rather, a separate tightline drain network should be installed or splash blocks should be used. As the settlement response of the site soils is variable and will be differential in nature, we recommend that the gravity utilities be provided with steep gradients to promote long- term performance. As some settlement between the pile supported buildings and surrounding fill supported utilities may occur, the use of flexible connections at transition points may be appropriate. 5.0 CLOSURE The conclusions and recommendations presented in this report are based, in part, on the explorations accomplished for this study. The number, location, and depth of the explorations were completed within the site constraints so as to yield the information utilized to formulate our recommendations. The future integrity of foundation depends largely on proper pile installation. The performance of pavements, and ancillary structures depends largely on site preparation, fill placement and construction procedures. Rittenhouse -Zeman would be available to provide geotechnical observation and construction observation services during the pile installation, earthwork and foundation construction phases of the project.

IIitshintuen 9S(X)5 -ice APPENDIX A SUBSURFACE EXPLORATIONS AND BORING LOGS APPENDIX A W -6069 Field Exploration The field exploration program conducted for this study consisted of excavating test pits and a program of 6 Dutch cone penetrometer probes. The approximate exploration locations were obtained in the field by hand -held compass and taping from site features shown on a plan provided by the project architects. The locations of the explorations should be considered as accurate as the degree implied by the method used. Test Pit Excavations Six test pits were excavated on 4 October 1989 with a rubber -tired backhoe by a local excavating contractor. Each test pit was continuously logged and observed by one of our experienced engineering geologists /geotechnical engineers. In -situ strength and quality attributes of materials encountered in the test pits were estimated by our field observer based on experience with similar soils and on the difficulty incurred during excavation. Disturbed, but representative, samples of the soils in the test pits were retrieved, classified in the field, and transported in plastic containers to our laboratory for further evaluation and classification. The depths shown on the test pit logs are approximate. The test pit logs presented in this appendix are based on the inspection of the samples secured and the field logs. Static Cone Penetrometer Probes Six static cone penetrometer probe or Dutch cone test was performed for this project on 9 October 1989 by an exploration company under subcontract to our firm. The equipment used for this test consists of a cone and friction sleeve which are advanced hydraulically by rods reacting against a drill truck. The static cone penetration test is performed as follows: 1) the cone is pushed down by an inner rod and the point resistance is recorded; 2) the cone and the sleeve are then pushed and their combined resistance is measured; 3) the cone resistance is subtracted from the total resistance to provide the frictional resistance. A direct correlation between point resistance and the bearing capacity of the soils is obtained. The relative density or consistency of the soil probed is empirically related to the cone resistance. Comparing the cone bearing capacity and the friction ration (sleeve friction /cone bearing) provides an interpretive soil classification based on the Dutch Cone soil classification chart prepared by J. H. Schmertman, 1969. The descriptive soil interpretations presented on the static cone penetrometer probe logs have been developed by using this classification chart as a guideline. Modifications to the classifications were developed according to correlations of soil types disclosed in the boring performed on the site and careful interpretation of the probe results. The detailed interpretive log of the static cone penetrometer probe accomplished for this study is presented subsequently. RZA aror RITTENIIOUSE -ZEMAN & ASSOC., INC.
