The initial report lacked some information that Mason County requires with a Geotechncial Report. Public Works received the information through E Mail on August 10, 2006. The Email is considered an addendum to the report. The report addresses an unstable slope that has been active for ears. The slide is encroaching on p p Y 9 the southbound highway lane. Plans are to install a shear key/buttress to stabilize the landslide. The buttress is designed to or exceeding a safety factor of 1.25 for failure through, beneath, and overtop. Stability analysis was evaluated by using XSTABL Version 5.2. The shear key buttress will be adjacent to the highway. The buttress will have a 25-35 foot width. The buttress including a Jersey Barrier will be set back approximately six feet from the fog line. Construction involves a sequential excavation of slide debris in the toe area and backfilling the area with quarry spalls. The shear key will be founded in stable material Adequate erosion and sediment control features need to be implemented during land disturbing activities to protect neighboring properties and State waters from adverse stormwater runoff impacts. The migration or release of silty water or mud from the applicant's property will be considered a violation of County and State water quality protection regulations. The Geotechnical Report appears to satisfy the County's requirements for geotechnical reporting. Recommendations and comments contained in the report should be incorporated into the site development plans and made conditions for permit issuance. Please feel free to contact me at 724 if you have any questions regarding these comments, or if you feel any features need further discussion or attention.

This slope has been previously identified and is included in WSDOT's Unstable Slope Management System(USMS) I database. This slope is not currently programmed. If construction is delayed until 2004 or i later,the Geotechnical Division should review the landslide condition and if significant changes have occurred,review our recommendations contained in this report,and if necessary,update them. This report should be made available to prospective bidders and the Contractor in accordance with Section 1-02.4(2)of the WSDOT Standard Specifications. SLIDE HISTORY I This unstable slope has been active for many years. According to Maintenance,in more recent years,the landslide has been active with major events as recent as 1995 and 1996 that have crossed SR 101 with debris reaching the Puget Sound. Maintenance also reports that the landslide causes yearly problems with movement encroaching the roadway and eventually reaching the southbound lanes of SR 101. SITE CONDITIONS _Climate and Vegetation The project area is located in Mason County,along SR-101;between Lilliwaup and Eldon, Washington. The project lies within the Puget Lowland physiographic province and is strongly influenced by a moist maritime climate. Typically the winters are wet with cool temperatures while the summers are relatively dry and warm. Mean annual precipitation in at Lake Cushman Power House,which is located approximately 10 miles west,is about 90 inches(Desert Research Institute,2002). Vegetation consists primarily of western hemlock, Douglas fir,maple,cedar,and alder surrounding the slide mass. Trees have been cut on the i slide mass,so vegetation primarily consists of blackberry and other shrubby vegetation. i Regional Geology The Puget.Lowland physiographic province consists of a broad,low-lying region situated between the Cascade Range to the east and the Olympic Mountains to the west. The project area is in the southern portion of the Puget Lowlands. Repeated continental glaciations during the Pleistocene have carved the Puget Lowlands leaving thick deposits of glacial tills, glaciolacustrine silts and clays,and glaciofluvial sands and gravels. Glacial deposits related to alpine glaciation are interfingered within the continental glacial deposits along the margin of the Puget Sound. These glacial deposits are underlain by Tertiary bedrock units primarily associated with the Crescent Terrane,a complex sequence of marine basalts and terrestrial and marine sedimentary rocks(Babcock,Suczek,and Engebretson,1994). Since the end of the last major glaciation(Fraser)around 12,000 years B.P.,stream incisions and deposition and small-and large-scale mass wasting have modified the glacial deposits along the western margin of the Puget Lowlands. I E 96ed jpdgioda�j ydajoaE) �aelo iwwel i The Puget Lowlands are situated within an active region of seismicity,influenced by the subducting Juan de Fuca and the North American Plates as well as shallow and deep crustal stresses within the North American Plate. Earthquakes associated with this tectonic 1 environment can be characterized into three broad categories: 1)shallow focused crustal events,2)deep intra-plate events,and 3)subducting North American Plate interface events (Yelin,et.at.,1994). I Project Site Characteristics The MP 326.78 to 326.84 Vicinity Landslide is located adjacent to the Puget Sound,upslope of SR-101,and approximately'/,mile north of Lilliwaup,Washington. The landslide is approximately 350 feet wide and extends approximately 300 feet upslope of the highway,and generally slopes at 20 and 25 degrees. The headscarp,located around 300 feet left of centerline,is steep and ranges in height between 40 and 80 feet(Figure 2). The toe of the slide is approximately 15 feet in height,toes out near the highway level and actively encroaches onto the highway(Figure 3). The southern lateral scarp exposes the glacial outwash sands and gravels(Figure 4)which is underlain by glaciolacustrine silts.The headscarp and northern lateral scarp expose the contact between the alpine outwash sands/gravels and the glaciolacustrine silts with seepage at this contact. Eight bore holes were installed at four locations in the active landslide mass and just beyond i 3 the headscarp(Figure 5)(see Appendix B:Boring Logs)to characterize subsurface conditions and retain samples to evaluate engineering properties of the underlying soil units.`The bore i holes were instrumented with piezometers to monitor groundwater levels or slope inclinometers to define the configuration and depth of failure of the slide mass. From the bore holes and geologic mapping,three engineering units were developed and are referenced in Figure 6. These soil units are: Slide Debris: This soil unit consists of soft to medim stiff,moist to wet sand,silt, gravel,and some organics. Atterberg limits of the fine grained fraction of the unit yielded plastic indicies of 9 to 11. Observed thicknesses within this unit range from approximately 15 in the toe of the slide to 55 feet near the headscarp. Glacial Outwash Sands and Gravels: This outwash unit consists of loose to very dense,brown to gray,stratified sandy gravels and silty sands that overlie the glaciolacustrine silts. This unit is approximately 35 to 40 feet thick. Glaciolacustrine Silts: This unit generally consists of stiff to very hard,dark gray, silt to sandy silt. The thickness of this unit was not determined. t \. Monitoring revealed that groundwater within the slide mass is within 5 feet of the ground surface through much of the slide mass. A perched groundwater surface was identified in the Glacial Outwash Sand and Gravel unit. abed �pd oda� yaa�oab) - �jelo wwel l v 1, 1• ANALYSIS In addition to review of pertinent references,aerial photos and maps,and field visits,the bore hole information was used to develop two geologic cross sections(Figures 6.&7). Limit equilibrium stability analyses were performed to back analyze soil strengths within the landslide mass. This model was then used to evaluate stabilization altema ves. These alternatives were developed to achieve a minimum factor of safety of 125. Based on the geological and geotechnical information compiled to date,the failure mechanisms for the landslide has been interpreted to be large-scale translational(block)failure occurring within the glacio-lacustrine unit. Low shear strengths and elevated groundwater conditions are the main destabilization factors. RECOMMENDATIONS A variety of remediation measures were considered to stabilize the landslide. These included improved surface/subsurface drainage,regrading to a more stable configuration,and a variety of buttress configurations. Given the site conditions,we have developed a shear key/buttress design to stabilize the landslide. Construction of the shear key/buttress involves sequential excavation of the slide debris in the toe area of the landslide and backfilling the excavation with quarry spalls. The shear key portion is founded in stable material below the slide plane Uand the buttress portion provides increased shearing resistance to the landslide mass. We have sited the shear key buttress adjacent to the highway to limit excavation/backfill —- quantities(Figure 8). The buttress is designed to or exceeding a static factor of safety of 1.25 for failure through,beneath,and overtop the buttress. A typical buttress section is shown in Figure 8 illustrating the dimensions and approximate construction limits. The buttress should extend from Station 15+70 to 19+20. The buttress should have a minimum width of 25 to 35 feet,depending on the location, throughout the entire buttress. Based upon recommehdations from the Region design office,we have designed for a minimum setback distance from the existing fog line to the front edge of the rock buttress of 6 feet with a 2 foot wide jersey barrier directly in front of the buttress(Figure 8). The face of the buttress should be constructed at 1.51-1:1 V to a minimum height of 25 to 35 feet,depending on location(Point B). The rock buttress must be keyed into the undisturbed,dark gray lacustrine silt unit a minimum of 3 feet(Point A)specified in Figure 8. 'The excavation and backfilling must occur concurrently and continuously from one end of the buttress to the other. Open excavations should be limited to no more than 25 feet in length and not be allowed to stand open more than 4 hours. All excavated material should be considered waste and be disposed of off site. The excavation will encounter a small timber pile wall approximately 30 feet left of centerline. These timbers are creosoted and special - disposal measures will likely be warranted. i 2 96e -d oda �a oa ie pwe 5 d �P � 2�_ y � J - �1 I� . 1 I We have assumed that 1.5H:1 V temporary cut slopes will be used. Actual temporary slopes may vary depending on weather and groundwater conditions,as well as the Contractor's operations. The temporary backslopes are considered to be marginally stable. For this reason,extreme care should be used and exposure of workers should be minimized near temporary slopes. . Due to the anticipated high groundwater conditions present at this project site and concern for temporary slope stability,we strongly recommend that the buttress be constructed during the late summer to early fall. Localized sloughing from seepage should be anticipated in the backslope. I This design does not address the potential for continued localized instability in the headscarp area. This geologic process should not significantly effect the long term performance of the buttress. i L=ATIONS The conclusions and recommendations contained in this report are based on the Geotechnical Branch's understanding of the project and site conditions that existed at the time of field exploration and subsequent office analysis. These conclusions and recommendations assume that subsurface conditions,as observed in exploratory borings,are representative of the subsurface conditions throughout the project area. In addition,observations of groundwater. were made to characterize hydrologic conditions that could potentially affect design and construction of the project. These observations are sensitive to weather and climatic j conditions preceding the observations and,accordingly,conditions encountered during construction can be expected to vary from those observed. If the project plans are changed,or if during construction,subsurface conditions are-different from those observed during field explorations,or appear to be different beneath or beyond the excavations,the Geotechnical Branch should be advised so that we can assist in evaluating the impact.of these changed conditions on the project design and implementation. If there are any questions regarding the recommendations contained in this geotechnical report,then please contact Mike Mulhern at(360)709-5583 or Tom Badger at(360)709- 5461.

Due to greater than anticipated material costs for a high quality quarry spall backfill, we reevaluated using a lower quality backfill for a portion of the shear key buttress. We reanalyzed buttress sections using non-structural quarry spans(no degradation factor values) and a combination of non-structural quarry spalls with structural quarry spalls. Stability analysis was evaluated by limit equilibrium method utilizing XSTABL Version 5.2. In addition to the analysis used in the initial geotechnical investigation, lower strengths were used for the non-structural quarry spalls for this current analysis. In an attempt to achieve a minimum factor of safety design criterion of 1.25, we determined that the top half of the buttress can be constructed with non-structural quarry spalls provided that the bottom half is constructed with structural quarry spalls(see attachment). Quarry spalls must meet standard specification 9-13;however,the degradation factor may be eliminated for the non-structural quarry spall portion of the buttress. A revised figure for buttress construction is provided.
