Other Agencies of Jurisdiction: Department of Ecology Washington State Department of Transportation (for SR 181, Interurban Avenue South). Summary of Primary Impacts: Earth The site and surrounding hillside is part of the eastern slope of "Tukwila Hill" that extends between Interstate 405 to the south and Interstate 5 to the north. The submitted geotechnical report states that the ground in the vicinity of the proposed stabilization wall is comprised of highly- weathered sandstone bedrock at a depth of approximately 22 feet overlaid by soft soils consisting of either highly- plastic clays, silts or fill soils. This geologic composition has the potential for landslide activity, such as the landslide that initiated the need for this stabilization wall. The construction activities involved with the construction of the proposed stabilization wall will involve the grading and re- filling of between 400 and 1000 cubic yards of existing soils. Excavation and drilling for placement and construction of piling and the wall will expose sections of the hillside that are C:\ArtP /Sepa E02 -008 HillS.doc 2 SEPA Review — E02 -008 Hillcrest Apartments Slope Stabilization Wall June 26, 2002 now covered with vegetation. Review of the proposal for conformance with existing City codes for grading, excavation and the required Temporary Erosion and Sedimentation Control plan (TESC) will provide for adequate mitigation any anticipated Earth impacts. The applicant will also be required to obtain a temporary easement for the neighboring property owner for staging and access for construction machinery and materials. Air Normal emissions and dust associated with use of construction equipment will occur during construction of the project. All equipment will meet local, state, and federal emission standards. Air born dust from earth work and truck tire travel will be sufficiently mitigated by City Code and Puget Sound Clean Air Agency regulations for these impacts. Water The project site is on the landward side of Interurban Avenue S, which is separated from the Green / Duwamish River by a commercially developed parcel of land. The erosion and transfer of sediments into the river from grading, excavation, and construction is could occur if not properly managed. Project plans include the construction of a temporary equipment and truck wash pad and TESC pond to collect site stormwater and washing run -off. Existing City codes for grading, excavation and the required Temporary Erosion and Sedimentation control plan (TESC) will provide for adequate mitigation any anticipated Water impacts, therefore no additional mitigation is required. Plants The project site is vegetated with miscellaneous "weedy" species of grasses, shrubs, and small trees. These will be removed for staging and construction of the stabilization wall. Following completion of construction the ground surface will be planted with a hydro -seed grass mixture. New plants will be installed at the top and base of the retaining wall per the proposed landscape plan. Irrigation will be required per TMC 18.52.040 (H). Animals The site is developed with multi - family residential structures. The adjoining site to the proposed wall location is a previously cleared and currently undeveloped C:\ArtP /Sepa E02 -008 HillS.doc 3 SEPA Review — E02 -008 Hillcrest Apartments Slope Stabilization Wall June 26, 2002 and overgrown parcel. Neither site is possible animal habitat beyond small rodents or transitory songbirds. The Green / Duwamish River, across Interurban Avenue South and a developed parcel, contains fish, including the threatened Puget Sound Chinook Salmon and likely contains water mammals, such as otter. Therefore, no impacts to Animals are anticipated by this proposal. Energy/Natural Resources Project construction will use primarily fossil fuels for construction machinery. The completed project will not require any energy usage. Environmental Health No special emergency services will be required as a result of the proposed project. Short-term construction noise will be generated, but should not cause an impact due to the existing ambient noise from Interurban Avenue South and the vacant condition of the apartment building uphill from the area of construction. All equipment will be operated with required local, state, and federal noise suppression devices. City Code restricts construction generated noise between the hours of 10 PM and 7 AM. Land/Shoreline Uses The site contains Environmentally Sensitive Areas /Areas of Potential Geologic Instability. The stabilization wall is proposed to mitigate the effects of a landslide that occurred during the 1990's. This landslide resulted in the sliding of the north apartment structure adjacent to the slide area and rendering it un- inhabitable. After the stabilization wall is constructed the owners intend to stabilize and level this north building so it can again be inhabited. This project is therefore in keeping with the zoning and comprehensive plan intentions for multi - family use of this parcel. Housing As stated in Land/Shoreline Uses above, this project is the first step in re- activating a currently uninhabitable multi - family structure and, as such, will have a positive impact on the supply of available housing. C:WrtP /Sepa E02 -008 HillS.doc 4 • SEPA Review — E02 -008 Hillcrest Apartments Slope Stabilization Wall June 26, 2002 Aesthetics The stabilization wall is proposed to be constructed of coated vertical steel piles ("I" beam configuration) spaced approximately 5.5 feet on center bridged by treated wood lagging that will comprise the majority of the wall structure. The wall is approximately 180 feet in length and approximately 10 to 12 feet in height. The wall will be topped by a 4 foot galvanized chain link fence. The base of the wall will be approximately 20 feet above the nearby grade of Interurban Avenue S; the top of the wall will be approximately 32 feet above the grade of Interurban Avenue S. The wall plans as submitted did not provide for any screening of or aesthetic treatment of the wall surface. Therefore, the wall plans, as described above, indicate that the wall would create an adverse visual Aesthetic impact on the surrounding area and Interurban Avenue S right of way to the east. In response to the identification of the identified adverse Aesthetic impact, the applicant has submitted a landscape plan for screening of the stabilization wall and associated fence. The landscape plan will provide for a mix of deciduous and evergreen shrubs and trees along both the top and bottom of the wall. This method of wall and fence screening will provide adequate mitigation of the visual impact. Light/Glare There will be no light installations associated with this project. Temporary work hours are as described in Environmental Health above, temporary work lighting after daylight is not anticipated. Recreation There are no recreation facilities in the immediate vicinity of the proposed wall. A section of the Tukwila Trail System traverses the hillside behind the Hillside Apartments parcel, but is not within the area of proposed work. Historic /Cultural Preservation There are no places or objects listed on or proposed for national state or local preservation registers in the project vicinity. No areas of archeological significance are known to be in the project area. C:\ArtP /Sepa E02 -008 HillS.doc 5 SEPA Review — E02 -008 Hillcrest Apartments Slope Stabilization Wall June 26, 2002 Transportation All work and staging of equipment will occur on private property. Flaggers and traffic control may be necessary for the ingress and egress of trucks onto Interurban Avenue South and will be regulated through review for Public Works permitting. Public Services This project will not generate any increased need for public services such as police and fire. Utilities The area of the proposed project is not in the vicinity of water, storm sewer, sanitary sewer, natural gas, telephone /telecommunications or electrical utility lines. No interference or interruption of these utilities is anticipated by this project. Recommendation Determination of Nonsignificance (DNS).

Dear Mr. Thompson: This letter is a follow -up to our telephone conversation today regarding the probable Aesthetic impacts of the proposed landslide stabilization wall at the above address. Below I will recount the important points of our conversation and offer some possible approaches to addressing the concerns discussed. In our conversation I informed you that the plans as submitted did not provide adequate details of the finished portion of the wall that will be visible from the right -of -way along Interurban Avenue S; you then clarified what are planned to be the exposed materials. My understanding is that the exposed wall will be vertical steel piles (basically coated "I" beams) with horizontal treated lumber lagging placed in between the pilings. As the plans show, the wall will be approximately 12 feet in height above the grade at its base and will be topped with a chain -link fence for fall safety of anyone on the up -hill finished grade. The base of the wall will be approximately 20 feet above Interurban Avenue S with the wall extending up to 32 feet above the street with the fence an additional 4 feet above this height. Based on this information, the finished wall -face will have a negative Aesthetic environmental impact based on its "unfinished " - utilitarian appearance as seen from the surrounding downhill parcels and the right -of -way. The unfinished chain -link fence will add to this negative appearance. We then discussed some options for mitigating the 1 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 - 431 -3670 • Fax: 206 - 431 -3665 1 • aesthetic impact of the wall by various methods of screening. Below I will recount and add to various options discussed. • "Hard" Treatment of the Wall: Short of using a different material for the wall that would itself avoid an unfinished- utilitarian appearance (such as finished concrete), the addition of a "false" or outer -layer wall face may achieve this goal. You mentioned that you would be consulting an architect on this issue; the architect would be familiar with the variety of methods available for this purpose. The use of a coated and colored chain -link fence and posts would soften the appearance of a galvanized fence. Galvanized fences, in spite of their treatment, often rust. There are other fence choices available that may match whatever wall treatment is eventually chosen. However, a non -solid fence material may be the best choice for both security for and visibility from the uphill apartments. • "Soft" Treatment - Landscapinq: The use of plant material of various heights and different varieties could provide the needed Aesthetic mitigation. You mentioned that you were considering the use of "creeping" plants that will eventually grow over the wall. This may be an option in conjunction with a forefront plant layer that will provide screening while the creeping plants grow up the wall. From my observations of other applications, it will probably be necessary to include a trellis -like structure on the wall face on which creeping plants can become established. The use of a landscape architect would prove helpful on choosing durable, drought- resistant plants for this situation. The Landscape portion of Chapter 18.52 of the Tukwila Municipal Code (available on the City of Tukwila web site; www . ci . tukwi l a . wa . us) provides guidance on landscape requirements for the screening of blank walls. As I mentioned in our conversation, this should be the only outstanding information needed for the completion of this environmental review. Pursuant to TMC 18.104.130, this Request for Additional Information stops the legally mandated 120 -day review time limit of this application. Upon receipt of the requested information, the City will inform you within 14 days if any additional information is required to further- process your application. At this time the mandated review time limit will re- commence. If you have any questions or wish to discuss my comments, I can be reached at 431- 3670, extension 1163.

Dear Mr. Ing: We have completed a general review of the geotechnical aspects of the plans and specifications for the landslide stabilization wall to be constructed at 14891 Interurban Way South in Tukwila. We have completed two previous reports related to the subject site. An initial Geotechnicai Engineering Study for a landslide stabilization wail was completed on July 12, 1995, and a second Geotechnical Engineering Study for a Shoring /Landslide Stabilization Wall was completed on November 5, 1998. During the review process, we made recommendations to the structural engineer regarding changes to the plans. Those changes were incorporated into the finai set of plans that we reviewed. The plans we reviewed included Sheets SS1, SS2, and C1 through C3. CT En red the structural plans, which are dated October 31, 2001, and Evergreen ngineerinq Services Inc. prepared the civil engineering plans, which are dated January 31, 2001. In our judgement, the plans conform to the recommendations in our ggectechnical engineering rep-orts and subsequent letters (referenced above).

"Response to Third Party Review Comments...', by Shannon and `,Nilson, Inc., dated May 16, 2001. Dear Mr. Thompson: As discussed at the meeting on July 25, 2001, we are preparing this letter to further address the wall design concerns raised by Shannon and Wilson in their previous letters. • In regards to the active pressure used for the wail den, we are recommending a uniform lateral active earth pressure of 35H be used in the design. in our opinion, this pressure considers all failure planes (shallow and deep) passing through the wall location from the top of the wall to the bedrock. We recommend incorporating a surcharge: of 10H into the design to approximate the loading from seismically- induced earth pressures. We understand that an increase in allowable steel stress will be taken when applying these temporary pressures. In addition, the geotechnical values utilized for calculation of wall stability (passive pressure and anchor adhesions) incorporate a factor of safety of 1.5. In our opinion, this safety factor can be reduced to 1.2 when considering the seismic bads. • The wail monitoring program recommended in our letter dated July 9, 2001 should be implemented to monitor the long term performance of the wall. • The fill to be placed in front of the wall should be minimized from bath an economic and a slope stability standpoint. The piling contractors should place fill only as needed to reach the tieback elevation. None of the additional fill should be !eft in place. As discussed at the meeting, the large depths of till shown on the civil plans should not be placed. • For c:arity, a detail of proposed wail loading is attached to this letter. 34 Feb 1 5 02 04:23p GEOT• CONSULTANTS INC Helen Ing Investments Limited Partnershipclo CT Engineering iso,ucust 3, 2001 (425) -5561 P 2 JN 9839.S Pace We trust this letter clears up the remaining issues so that design and construction of the mitigation wail can take place.

As a summary of the project, a landslide occUrr, =r -12-1-224 below the northeast building of the complex. We conducted a study OT this slide at that time, but no repairs were made. Further soil movement has occurred since that time. We conducted another study of the site, drilling additional borings in the fall of 1998. Since about this time, the building, which is located near the scarp, has been unoccupied pending compietion of a retaining structure and necessary building repairs. Delays have come from a variety of sources including significant delays in the City of Tukwila approval process. The request for a permit to the City of ' onto and focus of our design effort is to repair the landslide that has occurred and to stabilize the ground in front of the northeast building. We have not studied other slopes or any cf the buiidings in the complex including the slope in front of the southeast building. The proposed stabilization extends beyond the limits of the landslide and will protect the northeast building. The southeast, adjacent building has not been endangered by the present landslide. The proposed stabilization method is a tied 'oack soldier -pile Nall with the piles socketed into bedrockI and the anchors embedded into bedrock. The design does not depend on development of the I'' adjacent property and is not intended to provide a retaining system for this development. We have assumed, however, that there is a possibility that earth movement can occur below the wall. Sncuid further movement occur: exposing the face of the soldier piles, additional lagging will be required. It• is not practical to excavate and lag the outside wall face until earth movement occurs. The design parameters we have provided are based en our practical experience, and as demonstrated in our previous letter, the parameters fall within the range of values given in published ocurnents by experts in the field. One can argue about which parameters to use in the design, but from a practical standpoint, measuring additional soil properties would require additional soil borings, sampling, rand- sophisticated- testing and analysis.

The piles are in rock and anchored to rock and are designed with 7 safety factors. Selected anchors will be tested to 200 percent capacity. A solution that would not impact costs too much (slight increase in anchorage steel) would be to test each anchor to 200 percent capacty \rather than the normal procedure of testing two anchors to 200 percent and the remainder to 130 percent of the anticipated load.►�� We recommend periodic monitoring of the top of the piles. We support monitoring on a yearly basis ik,e0�, (if and when significant slope failures occur below the wall, the deflection of the wall can be checked). If excessive pile deflection were to occur, additional anchors could be added. Based on our analysis, it is our opinion that this will not be required.

Dear Mr. Thompson: We offer the following responses to the geotechnical- related third party plan review comments prepared by Shannon & Wilson and dated March 21, 2000. Item numbers correspond to the numbered comments: Item 1 - The review of the project plans will need to be completed once the plans have been revised. Item 2 - The parking lot is not to be constructed as part of the proposed project. The design of the retaining structure does not rely on the presence of the soil above the bedrock on the downslope side of the wall for stability as the design is to carry all active pressures to the bedrock and start passive pressures at the bedrock elevation. Item 5 - Additional settlement on the order of 1 o 2 inches is pr_o_bable in the near future. In our opinion, this adjacent structure will need to be urtdtespi.araed to_make_it_I,.abitable. underpinning utilizing a deep foundation system (pipe piles) would transfer the building Toads below the influence of the proposed wall. Item 6 - Our borings indicate that the slide was a relatively deep - seated slide travelling approximately 15 feet below the surface as evidenced by the SPT blow counts of Borings 1 and 2 from the 1995 study. Item 7 - The assessment of the stability of the southern building ( #14893) was and is not within our scope of work at the site. The currently proposed wall appears to cover the area of observed active sliding. Item 8 - Due to the embedment of the base of the wall and all wall anchorage into the bedrock, the global stability of the wall is, in our opinion, not a concern. Item 9 - The fill shown behind the proposed wall on the recent plan will only be replacing - 3 9 - • • Helen ing Investments Limited Partnership c/o CT Engineering ' February 15, 2001 JN 98399 Page 2 sloughed soil and will be retained by the new wall. Imported, free- draining, granular fill should be utilized to promote drainage. Fill placed on the eastern side of the new wall will only serve as an access road and a working platform to install the piles and tiebacks for the wall. The wall design does not rely on the soil above the bedrock on the eastern side of the wall for stability. Item 10 - The recommended wall design pressure is 35(H), where H is the design retention height of the wall. We have performed a slope stability analysis on a typical cross - section through the known slide zone prior to slope movement. The stability analysis indicates that the upper, medium -stiff day soils would have an effective cohesion of approximately 250 psf and the lower medium -stiff to stiff clays would have a minimum cohesion on the order of 500 psf. The slope stability analysis is attached to this letter. Nearly all of the upper, softer clay soils were removed from the area behind the proposed wall due to the slide activity. These soils will be replaced by imported granular fill. In comparing the proposed lateral soil pressure with those suggested by Peck (1969) and Tschebotarioff (1973), we find general agreement. (See attached generalized calculations) The proposed loading diagram lies between these two theoretical loading schemes and, in our opinion, is appropriate for the observed site conditions. Item 11 - The wall is designed as a permanent structure. The temporary, unsupported condition exists at the site today and will be remedied by the wall installation. Item 12 - Recommendations for seismic wall loading are given in our letter, dated October 20, 2000. Item 13 - As previously discussed, granular, free - draining fill should be utilized. The backfill should be compacted to at least 90 percent of the maximum dry density as determined by Modified Proctor analysis. Access restrictions will likely prohibit large compaction equipment; however, the compaction should be conducted with relatively small compactors such as walk - behind rollers, backhoe- mounted hoepacks, or jumping jacks. The deflection of the wall should be monitored during construction. Item 14 - See the soil pressures recommended in our letter, dated October 20, 2000. - 4 0 - • • Helen Ing Investments Limited Partnership clo CT Engineering February 15, 2001 JN 98399 Page 3 We trust that the informations contained in this response package are sufficient to answer the questions posed.

We have completed two previous reports related to the subject site. An i niiial Geotedt nica! Engineering Study for a landslide stabilization wall was completed on J l 1 , 1995 and a second Geotechnical Engineering Study for a Shoring /Landslide Stabilization Wall was completed on November 5. 1998. The plans we reviewed included Sheets SS1, SS2, and 01 through C3. CT Engineering prepared the structural plans, which are dated October 28, 1999, and Mme- Tobiason, Inc. prepared the ci-vir engineering _plans, which are dated January, 20, 2000. A significant amount of time was spent tracing the various changes in design and deciphering the various correspondence related to the wall design. Also, we conducted slope stability analyses to justify our design criteria. After our review and analysis, we recommend the following: • The borings completed as part of the 1998 report indicate that the slide plane could extend as deep as the rock or hard silt. For this reason, the active soil pressure should be extended over the pile spacing to the level of the rock or hard silt soi!s..(approximately elevation 22 feet). This change to the plans was previously recommended in a memo from Jim Finley dated January 28, 1999. The stability of the block of colluvial soil o . . - •e left in •lace on the downslope side of the wa ca • -se relied upon in the long term. As an alternative, a second wall could be added at the toe of the slope (on the Wade Cook property) and /or a substantial permanent rock buttress could be constructed to stabilize the slide mass below the proposed landslide retention wall. (These options can be discussed further if applicable) A permanent easement would need to be granted for these structures. Since a second row of tiebacks will likely be needed to maintain stability of a taller, single wall,-"the-uniform soil pressure (35H) should be utilized in the design. • In addition, a uniform lateral seismic surcharge with a magnitude of 10H should be Helen /ng Investments Limited Partnership c/o CT Engineering October 20, 2000 JN 98399 Page 2 incorporated into the design. Where H is the design retention height of the wall extending up oPt- m elevation 22 feet. When performing stability analysis using this seismic surcharge pressure, the surcharge should be reduced to a point load that acts at 0.4H from the top of wall. Typically, the factor of safety is reduced from 1.5 to 1.2 when performing seismic analysis. To satisfy the questions posed by Shannon and Wilson, we will need to justify the soil design pressures. We can accomplish this, but the wall design will need to be changed and reviewed by our office prior to issuing a final plan review letter and response to the third party reviewer's comments.

The scope of our work consisted of exploring site subsurface conditions, and then developing this report to provide recommendations for general earthwork, retaining wall design, and pavements. This work was authorized by your acceptance of our proposal, P -4620, dated July 15, 1998. The project site is located below the Hillcrest Apartments. A landslide occurred at the crest of the slope below the Hillcrest Apartments in 1995. It is our understanding that a retaining wall is to be constructed to the east of the apartment buildings to stabilize the existing slope and for retaining the excavation for the parking lot. It is our opinion that such a _retaining wall is feasible. The foundation for this wall will need to be embedded into the underlying sandstone bedrock and;` tieback anchors will need to be installed in the rock to provide additional lateral support. Extensive subsurface drainage facilities may be needed for the construction of this project. avement sections shoulcFbe unaeriain by Imported granular fill and a geotextile fabric. The attached report contains a discussion of the study and our recommendations. Please contact us if there are any questions regarding this report, or if we can be of further assistance during the design and construction phases of this project.

Principal - 5 0 - GEO T ECHNICAL ENGINEERING STUDY Proposed Parking Facilities and Retaining Walls 14391 Interurban Avenue South Tukwila, Washington This report presents the findings and recommendations of our geotechnical engineering study for the site of a proposed parking facility to be located at 148.91 Interurban Avenue South in Tukwila, Washington. The Vicinity Map, Plate 1, illustrates the general location of the site. The parking facility will lie between Interurban Avenue South and the Hillcrest Apartments. The grading of the parking lot will require cuts of 16 to 20 feet in height near the western property line. retaining wall will support this cut. This wall will have a dual purpose of supporting the excavation slope and stabilizing the existing slope immediately below the Hillcrest Apartments. A landslide occurred in the area of the new retaining wall in 1995. No work has been done to stabilize the slope since the occurrence of the earth movement. SITE CONDITIONS Surface The project site slopes upwards to the west from an elevation of approximately 20 feet at Interurban Avenue South to an elevation of approximately 48 feet at the western property line. Most of the slope is located on the western one-half of the site. The site is currently cleared near Interurban Avenue South and covered with small trees and brush near the western property line. The ground surface is wet and soft. A backhoe was unable to traverse the site to clear into the ten e - - , • e n ng Subsurface The subsurface conditions were explored by drilling four test borings at the approximate locations shown on the Site Exploration Plan, Flate 2. A fifth test boring was planned, but could not be drilled due to soft surface conditions. The field exploration program was based upon the proposed construction and required design criteria, the site topography and access, the subsurface conditions revealed during drilling, and the scope of work outlined in our proposal. The borings were drilled on September 29 and 30, 1998, using a small, track- mounted drill rig. Samples were taken at 5 -foot intervals with a standard penetration sampler. This split -spoon sampler, which has a 2 -inch outside diameter, is driven into the soil with a 140 -pound hammer falling 30 inches. The number of blows required to advance the sampler a given distance is an indication of the soil density or consistency. A geotechnical engineer from our staff obsenied the drilling process, logged the test borings, and obtained representative samples of the soil encountered. The Test Bcring Logs are attached as Plates 3 through 6. In addition to the four test borings drilled for this work, we also had in our files the results of two test borings drilled for the Hillcrest Apartments in 1995. Near the western property line of the _-,_ suGj ect site, highly - weathered sandstone bedrecicwas found in borings 8 -3, E -4, B-1-95, and E -2- 95 at an elevation of approximately 22 feet. Overlying the sandstone bedrock are soft soils —51- Wade Cook Financial Corporation November 5, 1998 JN 98399 Pace 2 consisting either of highly - plastic days, silts, or fill soils. Boring 8 -1, located near the northern property line, in the center of the site, also encountered rock at approximately elevation 22 feet. Overlying the rock was approximately 4 feet of silt. Boring 2, located in the center of the site and near Interurban Avenue South, encountered approximately 20 feet of fill and days overlying the highly - weathered sandstone and siitstone. At this location, the bedrock was at an elevation of approximately 10 feet. The final logs represent our interpretations of the field logs and laboratory tests. The stratification lines on the logs represent the approximate boundaries between soil types at the exploration locations. The actual transition between soil types may be gradual, and subsurface conditions can vary between exploration locations. The logs provide specific subsurface information only at the locations tested. If a transition in soil type occurred between samples in the borings, the depth of the transition was interpreted. The relative densities and moisture descriptions indicated on the test boring logs are interpretive descriptions based on the conditions observed during drilling. Groundwater No groundwater seepage was observed while drilling. However, the soils are highly impervious, thus seepage can be relatively slow except in more porous layers. The soils above the rock were wet in several of the borings. Water levels were net monitored after the drilling process and the test borings were left open for only a short time period. Therefore, the lack of seepage in the borings does not necessarily indicate no groundwater was present. We anticipate that groundwater levels will be near the interface between the fill and weathered soils, and the sandstone rock, or within more pervious layers of the sandstone. It should be noted that groundwater levels vary seasonally with rainfall and other factors. CONCLUSIONS AND RECOMMENDATIONS General The construction of this parking lot will be difficult and expensive due to relatively poor soil conditions. Cuts of approximately 20 feet in height will be required at the southwest corner of the property. A large retaining wall will be required along the western property line and extending over a portion of the southern property line. If the wall is to be used to provide stability to the Hillcrest A•artments, the wall will need to be a••roximatei' 20 feet hi •h alone the entire western boundary of the subject property. t would also need to extend to the northern property line. We recommend that the top or t e wa -extend to Elevation 48 feet and that the west, or upslope, side of the wall be backfilled with imported free - draining pit -run gravel. The retaining wall will need to be constructed using steel, wide - flange soldier piles set in concrete - filled holes drilled into the sandstone bedrock. The soldier piles will need to restrain approximately 26 feet of soft, partially- disturbed soils. Thus, _Lateral earth pressures on the walls will be very large. It will be necessary to tie the soldier piles -back with permanent anchors extending into the bedrock and across the western property line. Although the soils exploration drill was able to penetrate the sandstone bedrock, the drilling contractor may encounter harder layers in the rock that would require use of special drills or coring. Access to the site for equipment will be difficult due to soft soil conditions. It will be necessary to construct a roadway of quarry spells placed over filter fabric to provide access for the drill rig along the proposed retaining wall location. Interior roads will be required to provide truck access to haul -52- (:,,,1orh Cnntrillnn /S. Inc. Wade Cock Financial Corporation November 5, 1998 JN 98399 Page 3 excavated material from the job site and to bring in construction materials. We recommend that a trackhoe be utilized for the excavation. Dozers or front -end loaders will have difficulty moving earth on the site. The soils are highly plastic and ver se si ive o disturbance. All excavated soils should be remove • from the site. The excavated soils are not suitable for structural fill_, inc using utilit\ backfill. is will require imported granular fill for wall backfill, utilities, and base material under the pavement. The west retaining wall will stabilize the slope; however, extensive work will still need to be done on the eastern two buildings of the Hillcrest Apartment complex. The earth movement under the foundations of these buildings is associated not only with slope instability, but consolidation of very loose soils underlying the buildings. The buildings will need to be underpinned, and the building and floors releveled. Geotech Consultants, Inc. should be allowed to review the final development plans to verify that the recommendations presented in this report are adequately addressed in the design. Such a' plan review would be additional work beyond the current scope of work for this study, and it may include revisions to our recommendations to accommodate site, development, and. geotechnical constraints that become more evident during the review process. West Retaining Wall This section presents design considerations for cantilevered or tied -back soldier pile walls, as a soldier pile wall appears the most appropriate method fcr retaining the western slope. Since the most suitable choice of anchors is primarily dependent on a number of factors under the contractor's control, we suggest that the contractor work closely with the structural engineer during the shoring design. The design should be submitted to Geotech Consultants, Inc. for review prior to beginning site excavation. We are available and would be pleased to assist in this design effort. Cantilevered and tied -back soldier pile shoring systems have proven to be an efficient and economical method for providing excavation shoring. Tied -back walls are typically more economical than cantilevered walls where the depth of excavation is greater than 15 feet, or where high lateral soil pressures need to be resisted. Soldier Pile Installation Soldier pile walls should be constructed prior to commencing any excavation below existing grades by setting steel H -beams in driiled holes and grouting the spaces between the beams and the soil with concrete for the entire height of each drilled hole. Excessive ground loss in the drilled holes must 'be avoided to reduce the potential for settlement on the adjacent western property. If water is present in a hole at the time a soldier pile is poured, concrete must be treried to the bottom of the hole. Use of casing or slurry methods is recommended in areas where caving is encountered in the drilled hole. As excavation proceeds downward, the space between the piles should be lagged with treated timber, and any voids behind the timbers should be filled with pea gravel. The prompt and careful installation of lagging is important, particularly in loose or caving scil, to maintain the integrity of the excavation and provide safer working conditions. Additionally, care must be taken by the excavator to remove no more soil between the soldier piles than - 5 3 - Cantor-4 CnnwiltantS. Inc. -7x Wade Cook Financial Corporation:-. November 5, 1998 JN 98399 Page 4 is necessary to install the lagging. Caving or overexcavation during lagging placement could result in loss of ground on neighboring properties. Lagging specifications are as • follows: 1. The maximum distance between the drilled holes should. be 5 feet (edge -to- edge). 2. Timber lagging shbuld be designed for an applied lateral pressure of 30 percent of the design wall pressure, if the pile spacing is Tess than three pile diameters. For larger pile spacings, the lagging should be designed for 50 percent of the design load. Soldier Pile' Wall Design Cantilevered shoring or tied -back shoring having one row of tiebacks, with a level backslope, should be designed for an active soil pressure equal to that pressure exerted by an equivalent fluid with a unit weight of 55 pcf. If two rows of tieback anchors are needed, a uniform lateral active pressure of 35H psf should be used for design. H is the effective retainage height of the wall, beginning at an elevation of 22 feet. The active pressure on the west wall extends to the weathered rock, which was found at an elevation of 22 feet. Elsewhere, the active pressure extends to 2 feet below excavation level. Slopes above the shoring walls will exert additional surcharge pressures. These . surcharge pressures will vary, depending on the configuration of the cut slope and shoring wall. We can provide recommendations regarding slope surcharge pressures when the preliminary shoring design is completed. The lateral movement of the soldier piles will be resisted by an allowable passive pressure equal to that pressure exerted by a fluid with a density of 450 pcf in the weathered rock only. The soft days exert no allowable passive pressure. This passive pressure acts on two times the grouted pile diameter. The minimum embedment below the floor of the excavation for cantilever soldier piles should be equal to the height of the "stick -up ". The vertical capacity of soldier piles will be developed by a combination of frictional shaft resistance along the embedded length and pile end- bearing in the rock. Pile Shaft Friction Pile End Bearing 1,000 psf 10,000 psf The above values assume the following: • The excavation is level in front of the soldier pile. • The bottom of the pile is embedded a minimum of 15 feet below the floor of the excavation. • The bottom of the drilled hole is cleaned of loose soil and rock using a mud bucket. -54- f:anwrh Consultants, Inc. Wade Cock Financial Corporation November 1998 JN 98399 Page 5 • The concrete surrounding the embedded portion of the pile must have sufficient bond and strength to transfer the vertical load from the steel section through the concrete into the soil. Tieback Anchors Tieback anchors will need to extend into the weathered rock, thus, the anchors will need to be placed at an inclination of up to 45 degrees. It will likely be necessary to provide extra length on the "no -load" portion of the tieback reinforcement. This allows lengthening of the anchors to reach rock. The tieback will derive its capacity from the rock -grout strength developed in the weathered rock. Based on the results of our analyses and our experience at other construction sites, we suggest using an adhesion value of 1,500 psf in the weathered rock for conventional single- stage, grouted anchors. Soil conditions and soil -grout adhesion strengths typically vary over any site. Therefore, we recommend substantiating the anchor design values by proof - testing all tieback anchors. Additionally, at least two anchors in each soil or rock type encountered should be performance - tested to 200 percent of the design anchor load to evaluate possible anchor creep. These performance tests should be completed early in the anchor installation process, particularly if small- diameter or post- grouted anchors will be used. The remaining anchors should be proof - tested to at least 135 percent of their design value before being "locked off." After testing, each anchor should be locked off at a prestress Toad of 80 to 100 percent of its design load. If caving or water - bearing soil is encountered, the installation of tieback anchors will be hampered by caving and soil flowing into the holes. It will be necessary to case the holes, if such conditions are encountered. Alternatively, the use of a hollow -stem auger with grout pumped through the stem as the auger is withdrawn would be satisfactory, provided that the injection pressure and grout volumes pumped are carefully monitored. All drilled installations should be grouted and backfilled immediately after drilling. No drilled holes should be left open overnight. Excavation and Shorina Monitoring Prior to installing shoring or commencing excavation, we recommend making an extensive photographic and visual survey of-the project vicinity. This documents the condition of buildings, pavements, and utilities in the immediate vicinity of the site in order to avoid, and protect the owner from, unsubstantiated damage claims by surrounding property owners. The existing Hillcrestt Apartments have suffered extensive foundation settlement and are likely to experience some additional settlement in the course of this work. The soldier pile walls should be monitored during construction to detect soil movements. To monitor their performance, we recommend establishing a series of survey reference points to measure any horizontal deflections. Control points should be established at a distance well away from the walls and slopes, and deflections from the reference points should be measured throughout construction by survey methods. At !east every third soldier pile should be monitored by taking readings at the top of the pile. We suggest taking the readings at least three times during the construction process. -55- r,n/cri, f nneultnnts. Inc. /Vide Cook Financial Corporatio :' November 5, 1998 JN 98399 Page 6 Drainage Considerations A drainage composite should be placed against the lagging prior to constructing a permanent concrete wall facing. We recommend that weep holes be located no more than 6- feet -on- center at the base of the wall and 6 feet up from the base of the wall. A subsurface drain should also be installed at the base of the wall. This drain should consist of 4 -inch, perforated PVC pipe surrounded by at least 6 inches of 1- inch - minus, washed rock wrapped in a non - woven, geotextile filter fabric (Nlirafi 140N, Supac 4NP, or similar material). In addition to the drain at the base of the retaining walls, under - pavement drains will likely prove necessary. We recommend that our engineers review conditions when the site is cut to grade. At that time, we can provide recommendation for drain locations. The project bid documents should provide provisions for the installation of at least two drains across the property. Pavement Areas All pavement sections should be supported on at least 16 inches of granular fill, such as small quarry spells (2 1/z -inch- minus) or pit run sand and gravel with at least 40 percent gravel (retained on No. 4 sieve), placed over a woven geotextile fabric. The subgrade should be in a stable, non - yielding condition at the time of paving. To evaluate subgrade strength, we recommend that a proof roll be completed with a heavy construction vehicle on areas to be paved, immediately before paving. Additional structural fill may be needed to stabilize excessively soft, wet, or unstable areas. We recommend using Mirafi 500X characteristics. The subgrade should be evaluated by Geotech Consultants, Inc., after the site is stripped and cut to grade. Recommendations for the compaction of structural fill beneath pavements are given in a later sub - section entitled General Earthwork and Structural Fill. The performance of site pavements is directly related to the strength and stability of the underlying subgrade. The pavement for lightly- loaded traffic and parking areas should consist of 2 inches of asphalt concrete (AC) over 4 inches of crushed rock base (CRB) or 3 inches of asphalt - treated base (ATB). This pavement section is based on our experience in the area and on what has been successful in similar situations. Some maintenance and repair of areas can be expected, especially considering the soft nature of the near - surface soils on the eastern side of the site. To provide for a design 1 without the need for any repair would be uneconomical. General Earthwork and Structural Fill Structural fill is defined as any fill placed under a building, behind permanent retaining or foundation walls, or in other areas where the underlying soil needs to support loads. All structural fill should be placed in horizontal lifts with a moisture content at, or near, the. optimum moisture content. The optimum moisture content is that moisture content that results in the gre igst compacted dry density. The mcisture content of fill is very important and must be closely controlled 'during the filling and compaction process. The allowable thickness of the fill lift will depend on the material type selected, the compaction equipment used, and the number of passes made to compact the lift. The loose lift thickness should not exceed 12 inches. We recommend testing the fill as it is placed. If the fill is not compacted to specifications; it can be - recompacted- before-another lift-is-placed.. -- This- eliminates - 5 6 - r- r,..velflO.,.,ec T„rr Wade Cook Financial Carporatioi. November 5, 1998 JN 98399 Page 7 the need to remove the fill to achieve the required compaction.

Structural fill placed on this site should consist of a coarse, well- graded granular soil with a silt or clay content of no more than 5 percent. The percentage of particles passing the No. 200 sieve should be measured from that portion of soil passing the three - quarter -inch sieve. We recommend the use of quarry spalls under the placement. Samples of potential fill should be reviewed by Geotech Consultants, Inc. prior to their use. LIMITATIONS The analyses, conclusions, and recommendations contained in this report are based on site conditions as they existed at the time of our exploration and assume that the soil encountered in the test borings is representative of subsurface conditions on the site. If the subsurface conditions encountered during construction are significantly different from those observed in our explorations, we should be advised at once so that we can review these conditions and reconsider our recommendations where necessary. Unanticipated soil or rock conditions are commonly encountered on construction sites and cannot be fully anticipated by merely taking soil samples in test borings. Subsurface conditions can also vary between exploration locations. Such unexpected conditions frequently require .making additional expenditures to attain a properly constructed project_ It is recommended that the owner consider providing a contingency fund to accommodate such potential extra costs and risks. This is a standard recommendation for all projects. This report has been prepared for the exclusive use of NNade Cook Financial Corporation, and its representatives, for specific application to this project and site. Our recommendations and conclusions are based on observed site materials, and selective laboratory testing and engineering analyses. Our conclusions and recommendations are professional opinions derived in accordance with current standards of practice within the scope of our services and within budget and time constraints. No warranty is expressed or implied. The scope of our services does not include services related to construction safety precautions, and our recommendations are not intended to direct the contractor's methods, techniques, sequences, or procedures, except as specifically described in our report for consideration in design. We recommend including this report, in its entirety, in the project contract documents so the contractor may be aware of our findings. -57- /'nnc,illnn/c rnr Made Cock Financial Corperatic November 5, 1998 JN 98399 Page 8 ADDITIONAL SERVICES In addition to reviewing the anal plans, Geotech Consultants, Inc. should be retained to provide geotechnical consultation, testing, and observation services during construction. This is to confirm that subsurface conditions are consistent with those indicated by our exploration, to evaluate whether earthwork and foundation construction activities comply with the general intent of the recommendations presented in this report, and to provide suggestions for design changes in the event subsurface conditions differ from those anticipated prior to the start of construction. However, our work would not include the supervision or direction of the actual work of the contractor and its employees or agents. Also, job and site safety, and dimensional measurements, will be the responsibility of the contractor.

'' 14391 INTERURBAN A/ TUKWILA, WA j Cole: • A Report's Recommendations Are Not Final )00 not overrely on the construction recommendations included in your report. Those recommendations are not anal, because geotechnical engineers develop them principally from judgment and opinion. Geotechnical engineers can finalize their recom- mendations only by observing actual subsurface conditions revealed during construction. The geotechnical engineer who developed your report cannot assume responsibility or liability for the report's recommendations if that engineer does not perform construction observation. A Geotechnical Engineering Report Is Subject To Misinterpretation Other design team members' misinterpretation of geotechnical engineering reports has resulted in costly problems. Lower that risk by having your geotechnical engineer confer with appropriate members of the design team after submitting the report. Also retain your geotechnical engineer to review perti- nent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering report. Reduce that risk by having your geotechnical engineer participate in prebid and preconstruction. conferences, and by providing construction observation. Do Not Redraw the Engineer's Logs ) Geotechnical engineers prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical, engineering report should never be redrawn for inclusion in architectural or other design drawings. Only photo- graphic or electronic reproduction is acceptable, but recognize that separating' logs from the report can elevate risk. Give Contractors a Complete Report and Guidance Some owners and design professionals mistakenly believe they can make contractors liable for unanticipated subsurface condi- tions by limiting what they provide for bid preparation. To help prevent costly problems, give contractors the complete geotech- nical engineering report, but preface it with a clearly written let- ter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with the geotechnicai engineer who prepared the report (a modest fee may be required) and /or to conduct additional study to obtain the specific types of information, they need or prefer. A prebid conference can also be valuable. Be sure contractors have suffi- cient time to perform additional study. Only then might you be in a position to give contractors the best information available to you, while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions. Read Responsibility Provisions Closely Some clients, design professionals, and contractors do not recognize that geotechnical engineering is far less exact than other engineering disciplines. This lack of understanding has created unrealistic expectations that have led to disappoint- ments, claims, and disputes. To help reduce such risks, geot- echnical engineers commonly include a variety of explanatory provisions in their reports. Sometimes labeled "limitations ", many of these provisions indicate where geotechnical engi- neers responsibilities begin and end, to help others recognize their own responsibilities and risks. Read these provisions closely. Ask questions. Your geotechnical engineer should respond fully and frankly. Geoenvironmental Concerns Are Not Covered The equipment, techniques, and personnel used to perform a geoenvironmental study differ significantly from those used to perform a geotechnical study. For that reason, a geotechnical engineering report does not usually relate any geoenvironmen- tal findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regu- lated contaminants. Unanticipated environmental problems have led to numerous project failures. If you have not yet obtained your own geoenvironmental information, ask your geotechnical consultant for risk management guidance. Do not rely on an environmental report prepared for someone else. Rely on Your Geotechnical Engineer for Additional Assistance Membership in ASFE exposes geotechnical engineers to a wide array of risk management techniques that can be of genuine ben- efit for everyone involved with a construction project. Confer with your ASFE- member geotechnical engineer for more information.
