The City must have full and unrestricted use and benefit of the facilities, both from the .. operational and safety standpoint. 2. Only minor incidental work,replacement if temporary substitute facilities,or correction or repair work remains to reach physical completion of the work. DRAINAGE TUNNEL.WPD 8 May 3,1"6 .. The Contractor's request shall list the specific items of work in subparagraph two above that remains to be completed in order to reach physical completion. The Engineer may also establish the Substantial Completion Date unilaterally. If, after this inspection, the Engineer concurs with the Contractor that the work is substantially complete and ready for its intended use,the Engineer, by written notice to the Contractor, will set the Substantial Completion Date. If, after this inspection the Engineer does not consider the work substantially complete and ready for its intended use, the Engineer will, by written notice, so notify the Contractor giving the reasons therefor. Upon receipt of written notice concurring in or denying substantial completion, whichever is applicable, the Contractor shall pursue vigorously, diligently and without unauthorized interruption, the work necessary to reach Substantial and Physical Completion. The Contractor shall provide the Engineer with a revised schedule indicating when the Contractor expects to reach substantial and physical completion of the work. The above process shall be repeated until the Engineer establishes the Substantial Completion Date and the Contractor considers the work physically complete and ready for Final Inspection. 1-05.11(2) Final Inspection and Physical Completion Date. When the Contractor considers the Work physically complete and ready for Final Inspection, the Contractor by Written Notice, shall request the Engineer to schedule a final inspection. The Engineer will set a date for Final Inspection.

Upon correction of all deficiencies, the Engineer will notify the Contractor and the Contracting Agency, in writing, of the date upon which the work was considered physically complete. That date shall constitute the Physical completion date of the Contract, but shall not imply all the obligations of the Contractor under the Contract have been fulfilled. 1-05.11(3) Operational Testing. It is the intent of the City to have at the Completion Date a complete and operable system. Therefore when the work involves the installation of machinery or other mechanical equipment; street lighting,electrical distribution of signal systems; building; or other similar work, it may be desirable for the Engineer to have the Contractor operate and test the work for a period of time after final inspection but prior to the Physical Completion Date. DRAINAGE TUNNEL.WPD 9 May 3,1996 Whenever items of work are listed in the Contract Provisions for operational testing they -- shall be fully tested under operating conditions for the time period specified to ensure their acceptability prior to the Physical Completion date. In the event the Contract does not specify testing time periods, the default testing time period shall be fourteen (14) calendar days. During and following the test period, the Contractor shall correct any items of workmanship, materials, or equipment which proves faulty, or that are not in first class operating condition. Equipment, electrical controls, meters, or other devices and equipment to be tested during this period, shall be tested under the observation of the Engineer, so that the Engineer may determine their suitability for the purpose for which they were installed. The Physical Completion Date cannot be established until testing and corrections have been completed to the satisfaction of the Engineer. The costs for power,gas,labor,material,supplies,and everything else needed to successfully complete operational testing, shall be included in the various contract prices related to the system being tested, unless specifically set forth otherwise in the Bid Form. Operational and test period,when required by the Engineer, shall not affect a manufacturer's guaranties or warranties furnished under the terms of the Contract. 1-05.12 Final Acceptance. Section 1-05.12 will be deleted and replaced in its entirety with the following: The Contractor must perform all the obligations under the Contract before the Completion Date can be established. A Certificate of Completion for the work issued by the City will establish the Completion Date and certify the work as complete. The Final Contract Price may then be calculated. The following must occur before the Completion Date can be established and the Final Contract Price calculated. 1. The physical work on the project must be complete. 2. The Contractor, must furnish all documentation required by the Contract and required -- by law, necessary to allow the City to certify the Contract as complete. A Certificate if Completion for the work, signed by the City, will constitute acceptance of — the work, but shall not relieve the Contractor of the responsibility to indemnify, defend, and protect the City against any claim or loss resulting from the failure of the Contractor (or the subcontractors or lower tier subcontractors) to pay all laborers, mechanics, subcontractors, materialpersons,or any other person who provides labor, supplies, or provisions for carrying out the work. The issuance of this Certificate of Completion will not constitute acceptance _ of unauthorized or defective work or material. The City shall not be barred from requiring the Contractor to remove, replace, repair or dispose of any unauthorized or defective work or material or from recovering damages for any such work or material. Failure of the Contractor to perform all of the Contractor's obligations under the Contract shall not bar the City from unilaterally certifying the Contract complete so the Engineer may calculate a Final Contract Price as provided in Section 1-09.9.

May 1 1996 Woodward-Clyde 1.0 INTRODUCTION .. This report presents results of geotechnical investigations and tunneling recommendations for the proposed Mill Creek/SR 167 Drainage Tunnel project in Kent, Washington. The purpose of the geotechnical program described in this report was to evaluate subsurface conditions along the tunnel alignment and to provide geotechnical recommendations for the proposed project. This project was performed by Woodward-Clyde Consultants (WCC) for the City of Kent (City) in general accordance with the City's Consultants Services Contract, dated February 23, 1996. 1.1 PROJECT DESCRIPTION Mill Creek crosses under SR 167 just south of the East Valley Road overpass through two 48-inch diameter corrugated metal pipe (CMP) culverts. The creek enters the east end of the culverts between the Best Western and Bowen Scarff Ford Dealer properties, and exits about 75 feet southeast of the South 228 Street and 83rd Avenue South intersection (Figure 1). The City of Kent plans to construct a 60-inch diameter, 280-foot long drainage tunnel under SR 167 to increase the stormwater carrying capacity of Mill Creek. The new drainage tunnel (or culvert) will be constructed on the south side and parallel to the existing culverts. According to the City, the casing invert elevations are planned to be 25.5 and 26.5 feet for the west and east ends of the tunnel, respectively. The current design concept, presented by the City, involves installing steel casing under the roadway embankment by tunneling or pipe jacking methods, and providing sheet pile cofferdams at both ends to isolate the tunnel construction from the existing creek. The sheet pile cofferdams would be removed upon completion of the tunnel construction to make the final connection of the new channel to the existing creek alignment. The City will prepare the design and contract documents for the project. The City requested that WCC review the technical plans and specifications at the 60% level of completion and comment on the City's approach for dealing with geotechnical issues related to tunnel construction. 954044N.X\KENTRPT3.DOC 1-1 May 3. 1996 ire. Woodward-Clyde - 1.2 SCOPE OF WORK A proposal for performing this geotechnical work was submitted by WCC to the City on January 17, 1996. Notice to Proceed for the proposed scope of work was given on February 23, 1996, by Mr. Ken Langholz of the City. The purpose of the project was to evaluate subsurface conditions along the tunnel alignment and provide geotechnical recommendations for the proposed project. The scope of work for the project included the following: • Task 1 - Review of Existing Information. Gather and review readily-available geotechnical and geologic data for the project area. • Task 2 - Geotechnical Investigations. Plan and conduct field investigations to explore subsurface conditions along the tunnel alignment. Perform laboratory tests on selected soil samples to assist in classification and evaluation of the engineering properties of the site soils. • Task 3 - Engineering Analyses. Perform geotechnical engineering analyses of data obtained from the field exploration and laboratory testing program with respect to the proposed project. • Task 4 - Geotechnical Report. Prepare a report containing the results of the geotechnical investigation, including boring logs, generalized subsurface profile, and conclusions and recommendations for: - Anticipated subsurface conditions, including groundwater conditions - Groundwater control and dewatering - Jacking and receiving pit design - Potential surface settlement resulting from tunneling - Alternative tunneling methods (general) - Tunnel construction considerations • Task 5 - Review Plans and Technical Specifications Relating to Tunneling. "- Review and comment on the City's tunneling drawings and technical specifications at the 60% completion level. 954044NA�KENTRPT3.DOC 1-2 %[ay 3. 1996 Woodward-Clyde • Task 6 - Contractor Qualification. Review the City's qualifications section of the bid documents and the qualifications submittals, and provide recommendations to the City. `'- 1.3 EXISTING GEOTECHNICAL INFORMATION Three geotechnical exploration programs have been conducted in the vicinity of the drainage �'- tunnel location. In 1961 WSDOT drilled two borings adjacent to and south of Mill Creek prior to constructing SR 167. More recently WSDOT performed additional explorations for the HOV construction project for SR 167. The borings for both projects are presented in WSDOT (1992). Terra Associates (1995) also drilled a boring about 60 feet west of the tunnel near South 228th Street. The soil conditions encountered in these previous explorations generally consisted of low- density silty sand and clean sand in the upper 10 feet. These characteristics are discussed in more detail in Section 3.2. Groundwater was typically encountered at or just below the ground surface in the WSDOT borings. 954044NA1KENTRPT3.DOC 1-3 Mav 3. 1996 fto Woodward-Clyde 2.0 FIELD AND LABORATORY INVESTIGATIONS 2.1 FIELD EXPLORATIONS The subsurface exploration program was completed between March 4, 1996 and April 8, 1996. The program consisted of drilling three borings (designated BH-1 through BH-3) along - the tunnel alignment. The borings were drilled using both mud rotary and hollow-stem auger techniques. Borings BH-1 and BH-3 were advanced to depths of 311/2 feet, and Boring BH-2 was advanced through the embankment fill to a depth of 46'/2 feet below the ground surface. The boring locations were selected such that there was one near the jacking (BH-3) and receiving (BH-1) pits, and one (BH-2) near the midpoint of the tunnel under the highway embankment fill. Approximate locations of the explorations are shown on Figure 1. These locations were determined in the field by taping relative to known features. The approximate locations of Boring BH-5, which was drilled for a culvert replacement project west of the tunnel by Terra Associates (1995), and the 1961 WSDOT boring, No. L-1453, are also shown on Figure 1. Standard Penetration Tests (SPTs) were conducted at 5-foot intervals and at stratigraphic changes in each boring. Blowcounts recorded during the SPTs were used to estimate the density and consistency of in-place soil samples. Disturbed "bulk" samples of near-surface soils and less disturbed California drive samples were obtained at selected intervals in the explorations. Soil conditions revealed in each boring were recorded during the drilling program by a WCC geotechnical engineer. Appendix A includes logs of the borings and details of the subsurface explorations performed. 2.2 LABORATORY TESTING Laboratory tests were conducted to determine index properties of selected soil samples. .� These tests included water content, percent passing the No. 200 sieve, and grain-size determinations. Appendix B includes a brief discussion of the laboratory tests and test results. 9 5 4044N A\1iE V TRPT3.DOC 2-1 %fav 3.1996 Woodward-Clyde 3.0 SITE CONDITIONS 3.1 GEOLOGIC SETTING The project site is located in the southwest portion of the Renton Quadrangle on the eastern margin of the north-south trending Duwamish Valley. The Duwamish Valley occupies a glacially carved trough sculpted by four glacial advances and retreats. The trough has subsequently been partially filled with several hundred feet of post-glacial sediment supplied from advance and recessional melt-water streams, and more recently alluvium from the Green, Cedar, and White Rivers (Bronson 1989). Post-glacial sediments have accumulated continuously in the Duwamish Valley since the retreat of the Vashon Glacial, about 13,000 years ago. 3.1.1 Local Geologic and Groundwater Conditions The project site is located east of the Green River in the Duwamish Valley. The predominant near-surface soils in the Duwamish Valley are alluvium and overbank deposits comprised of sand, silt, clay, and peat. In the vicinity of the project site, the near-surface deposits consist chiefly of alluvium composed of silt and fine sand with local peaty areas up to 10 to 20 feet .. thick. The lower alluvial deposits consist primarily of medium and coarse sand deposited by the White River and are up to 75-feet thick (Mullineaux 1965). -- Bronson (1989) reported that during construction of the 16-mile long Valley Freeway (SR 167) from Renton to the King/Pierce County line, groundwater levels varied from a few inches to 6 feet below the ground surface. The deeper groundwater levels were recorded during August of 1959, indicating some seasonal variation. However, a I to 3-foot depth to groundwater was typical for most areas during the period from January to June, 1959. 3.1.2 Seismicity �- The project is located in the east-central Puget Sound, a region which has been characterized by a moderate to high level of seismicity and seismic hazards. Two potential seismic sources are significant to the proposed project: (1) the Cascadia subduction zone and (2) shallow crustal faults which, in general, have not been characterized to date. Within the Cascadia subduction zone, both interplate earthquakes, those events which rupture the interface �. (megathrust) between the subducting Juan de Fuca plate and the overriding North American plate, and intraplate earthquakes (within the Juan de Fuca plate) can occur. Shallow crustal 954044NA\KENTRPT3.DOC 3-1 Nfav 3. 1996 faults could probably generate a large earthquake anywhere in the Puget Sound including in _ the vicinity of the project site. The most significant seismic events in historical times in the Puget Sound region were the _. 1949 M 7.1 Olympia and 1965 M 6.5 Seattle-Tacoma earthquakes. The 1965 earthquake occurred about 5 to 10 km south of Kent at a depth of 60 km. Based on USGS seismic hazards maps, the peak ground acceleration at the site during a large seismic event could be as high as 0.3g. This level of acceleration has a 10% probability of exceedance in 50 years (Algermissen et al. 1990), which corresponds to approximately one occurrence in 500 years. The 500-year return period is consistent with that normally used by WSDOT in their roadway and bridge design projects. This peak ground acceleration level is also consistent with the Seismic Zone Factor (Z) in the Uniform Building Code (UBC 1994). 3.2 SITE CONDITIONS The following subsections describe the general surface and subsurface conditions along the alignment of the proposed drainage tunnel. Interpretations of the site conditions are based on site visits, subsurface explorations, and available geologic maps and reports. 3.2.1 Surface Conditions The proposed tunnel alignment is on the south side of the two existing 48-inch diameter CMP culverts which currently convey Mill Creek under SR 167. The top of the highway embankment fill is at about elevation 55 feet. approximately 231/7 feet higher than the adjacent ground surface near the tunnel portal locations (about elevation 311/2 feet). The embankment fill supports a four-lane divided highway and north bound off ramp to North Central Avenue. The highway drains towards the center, grass-covered, median. The embankment fill sideslopes are at about 1.8R I V to 1.9141V (horizontal:vertical) and are covered with grasses. The proposed jacking pit is located on the west side of the highway and south of Mill Creek. The jacking pit is bordered on the west side by a drainage ditch about 5 feet deep which is adjacent to the concrete driveway for a gravel company. The proposed receiving pit is on the east side of the highway, south of Mill Creek. The ground surface at both pit locations is vegetated with grasses. The existing CMP culverts are armored with riprap on the east side of _ the highway embankment. 954044NA�KENTRPTI DOC 3-2 May 3.1996 3.2.2 Previous Explorations Previous geotechnical explorations have been performed in the vicinity of the proposed tunnel project by WSDOT (1992) and Terra Associates (1995). WSDOT drilled multiple borings along the alignment of SR 167 in 1961 prior to construction. Two borings were drilled near Mill Creek. One boring was located about 10 feet south of the old Mill Creek (Station 884+85) alignment and indicated alluvium consisting of silty to clean sand from the ground surface down to 12 feet (bottom of hole). The other boring was about 375 feet south of Mill Creek (Station 881+20), and also indicated alluvium to 24 feet, except for a soft clay layer from 111/z to 15 feet below the ground surface. Groundwater was located about 3 feet below the ground surface (about elevation 26) in the hole drilled immediately south of Mill Creek. WSDOT also performed two explorations on the west side of SR 167 at the bottom of the embankment fill. Although the closest boring was located about 450 feet north of Mill Creek, soil and groundwater conditions are generally consistent with those noted w- previously. Terra Associates completed a single boring (Boring BH-5) for the nearby Mill Creek/South ~- 228th Street culvert replacement project. The boring was drilled about 60 feet west of the proposed tunnel during June, 1995. This boring was drilled to a depth of 26.5 feet. Results of the exploration indicate that subsurface conditions west of the site consist of about 5 feet of fill over loose silty sand and poorly graded sand. The groundwater table was about 7.5 feet below the ground surface (about elevation 26.3 feet). The location of Boring BH-5 is shown in Figure 1. 3.2.3 Soil Stratigraphy Surficial soils along the drainage tunnel alignment have been modified by construction of the highway embankment fill. Based on the soil borings, the fill soils associated with the highway embankment fill are underlain by a thick sequence of alluvial soil deposits. The base of the alluvial soils was not penetrated in any of the borings. A generalized geologic profile along the proposed tunnel alignment is shown on Figure 2. The location of this profile is indicated in Figure 1. Key features of this geologic profile are `• described below. Fill Soils The embankment fill soils in Boring BH-2 were about 28 feet thick and generally consisted of dense to very dense, poorly graded sand with silt and gravel (SP) to silty sand with gravel (SM). The bottom of the fill in Boring BH-2 was at approximately elevation 27 feet. Difficult 9 54044NA\KENTRPT3.DOC 3-3 h[av3, 1996 W.r drilling occurred at some intervals in Boring BH-2 where dense gravel and woody debris were encountered. Alluvium Alluvial soils were encountered at depth in all three borings. The surficial soils in borings BH- A and BH-3 appeared to be reworked alluvial soils. These soils consisted of poorly graded _. sand (SP) at Boring BH-1 and silty sand (SM) at Boring BH-3. The thickness of the reworked deposits could not be determined but appeared to be relatively thin. Physical properties appeared to be similar to those of the underlying undisturbed alluvial soils. At deeper depths the alluvium generally consisted of medium dense, poorly graded fine to medium sand (SP) and silty fine to medium sand (SM). Although sand and silty sand layers are likely interlayered, it appears that the west end (BH-3) and middle (BH-2) of the tunnel alignment have more silty sand near the surface, while the east (BH-1) consists of poorly graded sand. Up to 9 feet of sandy alluvial soils heaved up into the hollow-stem augers in BH-2 prior to switching over to mud rotary drilling techniques. A silt (ML) layer occurred at 24 feet below the ground surface (about elevation 7.5 feet) in Boring BH-3. The silt layer appeared to grade to interbedded silt, silty sand, and fine to medium sand. Interbedded silt layers were revealed from 20 feet below the ground surface (about elevation 11.5 feet) to the bottom of the hole in Boring BH-1. No silt layers were identified in Boring BH-2. Wood Debris Wood debris was encountered in all three borings. A thick section of tree was cored in Boring BH-2 from 33 to 37.5 feet below the ground surface (about elevations 17 to 21.5 illed through with the hollow-stem augers, but could be feet). The tree could not be dr penetrated with the tricone bit drilling using mud rotary techniques. Sample 12 from Boring BH-2 contained an 1 S-inch continuous core of the tree. Wood debris also occurred 16 feet below the ground surface (about elevation 15 feet) in Boring BH-1, and 14 feet below the ground surface (about elevation 17.5 feet) in Boring BH-3. Thin peat layers ('/4- to 3/4-inch) were encountered about 26 feet below the ground surface in Boring BH-1. It is our understanding that trees and other wood debris are common within the upper 20 feet of alluvial deposits in the Kent Valley. 3.2.4 Groundwater Groundwater occurred in all three borings. Groundwater was encountered 4.4 and 3.7 feet below the ground surface (about elevations 26.9 and 27.6 feet) in Borings BH-1 and BH-3, 954044NAU{ENTRPT3.DOC 3-4 Mav 3,1996 Woodward-Clyde respectively. The groundwater levels correlated closely to the surface water levels measured in Mill Creek at the time of drilling: elevation 27.4 feet and 27.6 feet for east and west ends of .� the existing culverts, respectively. Groundwater was encountered about 27'/z feet below the ground surface (about elevation 27 feet) in Boring BH-2 at the time of drilling. The above elevations are only approximate, as the ground surface at each boring location and the creek water levels were not surveyed, but only measured by taping, and referenced to the top of the south CMP culvert. Groundwater was reported at elevation 26 feet in the 1961 WSDOT boring, which was drilled about 10 feet south of Mill Creek. Groundwater recorded in Boring BH-5 (Terra 1995) was �-- at about elevation 26.3 feet. Based on the three borings drilled by WCC for this report and the two previous borings by others, it appears that the groundwater level ranges from elevation 26 to elevation 27. No groundwater observation wells were installed; therefore groundwater conditions are not stabilized levels, and may not necessarily be indicative of other times and locations. It is anticipated that the groundwater levels will vary depending on �.. the season. 3.2.5 Seismic Considerations Although a detailed evaluation of soil liquefaction potential was not within the scope of this study, it is likely that near-surface soils would liquefy under a design earthquake with a peak �. acceleration of 0.3g. The primary risk to the drainage tunnel during liquefaction will be lateral spreading and settlement of the roadway embankment. Either type of movement could alter �.. the function of the tunnel by changes in grade or by rupture of the pipe. The risk to the drainage tunnel could be reduced by improving the liquefaction resistance of near-surface soil. wax 954044NA`\KENTRPT3.DOC 3-5 %lay 3, 1996 Woodward-Clyde 4.0 CONCLUSIONS AND RECOMMENDATIONS This section presents conclusions and recommendations from WCC's geotechnical evaluations. These conclusions and recommendations involve the anticipated subsurface conditions along the tunnel alignment, groundwater control and dewatering, jacking and receiving pit design, surface settlements from tunneling, alternative tunneling methods, and tunnel construction considerations. 4.1 ANTICIPATED SUBSURFACE CONDITIONS The site conditions along the alignment of the tunnel are described in Section 3.2. These conditions indicate that loose to medium dense silty sand (SM) and poorly graded clean sand (SP) both above and below the water table will likely be encountered between the invert and crown of the tunnel. As shown in Figure 2, fill soils placed for construction of the SR 167 embankment are present near the upper portion of the tunnel, while the lower portion of the —. tunnel is expected to encounter undisturbed alluvium. There are several issues related to subsurface conditions along the alignment that will be critical for selecting appropriate tunnel construction methods and equipment. These include (1) loss-of-ground, (2) obstructions, and (3) groundwater control. The first two of these issues are discussed below. Groundwater control is discussed in the next section. 4A.1 Loss-of-Ground -- Avoiding or preventing loss-of-ground is critical because it could lead to settlement that can damage the existing highway and other improvements above the tunnel. Under worse-case _ conditions, significant loss-of-ground can result in sinkholes at the ground surface that are many feet deep. If flowing ground is encountered and not appropriately handled, sinkholes can develop rapidly and without warning. To categorize the anticipated conditions at the tunnel face, the soft-ground soil classification system given in Table 1 was used. Based on this classification system, the sand deposits above the groundwater table classify as "running" or "raveling" ground. The saturated sand layers below the groundwater table classify as "flowing" ground if not dewatered prior to —. excavation or if not stabilized in some other manner such as with grouting or with special pressurized face microtunneling equipment. After dewatering, these sand deposits will likely classify as "running" or"raveling" ground. 954044NXKENTRPT3.DOC 4-1 %fav 3. 1996 Woodward-Clyde These ground classifications indicate that a significant construction issue related to the loss of ground at the tunnel face could exist. To address this issue, the tunneling contractor will have to either improve the strength or stability of the ground or utilize special tunneling equipment and methods to control and minimize loss of ground. 4.1.2 Obstructions .� While loss of ground appears to be the most significant tunnel construction issue, the tunnel contractor will also have to anticipate the occurrence of obstructions from buried trees. A . cedar tree approximately 4'/2 feet thick was encountered in Boring BH-2, and other wood debris was found in Borings BH-1 and BH-3. The tree and wood debris occurred about 4 feet or more below the proposed invert of the tunnel. However, similar debris and tree remnants should be anticipated along the tunnel alignment. „- 4.2 GROUNDWATER CONTROL AND DEWATERING As discussed in Section 3.2.4, groundwater is expected to be encountered at approximately �.. the same elevation as Mill Creek. Available groundwater information suggests that the groundwater elevation will vary from approximately elevation 26 to 27 under normal flow conditions. During periods of high runoff in Mill Creek, higher groundwater elevations should be expected. These periods of high runoff typically occur during the fall and winter months. However, on occasions heavy summer rains have resulted in flooding of Mill Creek. The invert of the drainage tunnel will be at elevations 25.5 and 26.5 at the west and east ends of the tunnel, respectively. These elevations are at or below the recorded groundwater ... elevations, suggesting that positive groundwater control measures could be necessary to prevent flowing ground conditions and loss-of-ground at the tunnel face. �- A variety of groundwater control methods are available, including dewatering using wells, balancing the hydrostatic pressure using compressed air or pressurized face microtunneling equipment, ground freezing methods, and cement or chemical grouting. Several of these options do not appear viable for the drainage tunnel project: • Compressed air tunneling techniques are very expensive and are rarely employed at the present time due to availability of pressurized face microtunneling equipment that accomplishes the same purpose more safely and less expensively. • Ground freezing, although technically feasible, is usually more expensive than other options. May 3.1996 954044NAUCENTPPT3.DOC 4-2 r.r Woodward-Clyde • Cement grouting does not appear technically feasible. The sand deposits appear to be too fine grained with too high a percentage of fines (percent passing the No. 200 sieve) to allow penetration of the cement in the zone that would need to be stabilized. • Chemical grouting could be effective. This type of grouting would involve drilling horizontal holes ahead of the tunnel and injecting grout to strengthen and stabilize the sand deposits. While this approach may be feasible, it is difficult to verify the W success of the grouting work and it is also likely to be a relatively expensive approach. The two most effective groundwater control methods for this project appear to be either dewatering methods or the use of pressured face microtunneling equipment. -- 4.2.1 Dewatering Methods Dewatering might be accomplished using any one of several methods: well points, deep vertical wells, inclined (near horizontal) wells, or drains installed ahead-of-the face. Each of these methods is briefly described below. • Well points are usually limited to dewatering depths of 15 to 18 feet below the ground surfaces, although this depth can be increased by providing jet-eductor pumps at the bottom of the well point. The main disadvantage in using well points for this project is that they are usually spaced 6 to 10 feet apart. While this spacing is feasible at jacking and receiving pits, it would not be practical across SR 167. • Deep vertical wells are used where groundwater elevations or other considerations limit the use of well points. These wells are drilled deeper and are spaced further apart. From a technical standpoint, deep wells could be installed in the median area of the highway and on the outside edge of the shoulders without severely disrupting traffic and completed in below-grade vaults to provide access. Although deep wells appear to be technically feasible for the Mill Creek drainage tunnel project, it is understood from discussions with the City's staff that WSDOT may not allow deep wells on the shoulders or center median of SR 167, because of potential conflicts with WSDOT's HOV lane construction and because of the potential for ground settlement from dewatering. • Inclined (near horizontal) wells might be drilled from the bottom of the roadway embankment. In these sand deposits the horizontal drain holes would have to be cased to prevent the hole from collapsing and then a slotted well screen wrapped 954044NA\KENTRPT3.DOC 4-3 Ntav 3, 1996 Woodward-Clyde with a suitable geotextile installed in the drain holes to prevent piping and loss of ground. This is a relatively difficult construction operation, and even with careful construction techniques, it may not be possible to prevent some piping and loss of ground (and surface settlement) from occurring. While this approach would avoid — conflicts with WSDOT's HOV lane construction, it would still have to be approved WSDOT since dewatering could result in settlement of the SR 167 roadway. • Dewatering might also be accomplished ahead-of-the-face from inside the tunnel by drilling horizontal or sloping holes to install drains. However, this method of dewatering interferes with tunneling operations, and it is generally difficult to evaluate how effective this approach will be. The same issues described above for inclined wells would have to be considered to avoid piping and loss of ground. This approach would likely be acceptable to WSDOT since it would not conflict with WSDOT's HOV lane construction and the potential for settlement would be small. In the event that the tunneling contractor selects dewatering as a means of controlling the potential for flowing ground, the contractor should provide details of the groundwater control system and submit the plans for review. Specifications should require that the contractor's dewatering plans be prepared and stamped by a licensed engineer with expertise in the design of dewatering systems to assure that the dewatering system is correctly designed. Observation wells should be installed to monitor the effectiveness of any dewatering system which is implemented. ... 4.2.2 Pressurized Face Microtunneling Pressurized face microtunneling equipment is another option for providing effective �- groundwater control for this project. Typically this approach is not cost effective for such a short tunnel length because of the cost of equipment mobilization. However, in situations where flowing ground is present and groundwater cannot be controlled by deep wells or well points, pressurized face microtunneling offers one of the only reliable alternatives. With this method, face stability is maintained by applying a positive pressure at the tunnel face using a recirculating slurry to balance the soil and groundwater pressures and prevent loss of ground. If properly utilized, this type of microtunneling equipment will prevent loss-of- ground at the heading and minimize surface settlement without the need for dewatering. Use of pressurized face equipment will also minimize surface settlement and potential damage to adjacent structures and utilities that could result from dewatering or loss-of-ground during tunneling. ... 9 54044NX KENTRPT3.DOC 4-4 Mav 3, 1996 Woodward-Clyde 4.3 JACKING AND RECEIVING PIT DESIGN _. Two shaft excavations will be required for the project: one for the jacking pit, and the other for the receiving pit. The pipe will be installed from a jacking pit on the west side of the highway to a receiving pit located on the east side of the highway. The jacking pit and receiving pit will be excavated in the vicinity of Borings BH-3 and BH-1, respectively. The _ exact shape and dimensions of these shaft excavations are to be selected by the contractor to be compatible with the selected construction method and equipment. The jacking and receiving pit excavations will both likely be less than 10 feet deep. For -- stability and safety purposes, the contractor should provide and maintain during construction, a full perimeter shaft support system utilizing interlocking sheetpiles. The support system +� should be installed prior to excavation. Design of the support system should be the responsibility of the contractor. 4.3.1 Shoring System Temporary shoring systems (sheet piles) should be designed in accordance with the �— recommended lateral earth pressures (active and passive) shown in Figure 3. These pressure diagrams are based on the jacking and receiving pits being dewatered with a well point system. If sumps are used, the contractor should include hydrostatic pressures when designing the shoring system. The contractor should include allowances for construction equipment loads or other surcharge pressures in the design if greater than the 300 psf surcharge load shown on Figure 3. Seismic loading is not included since this is a temporary support structure. As a minimum, the upper one foot of soil (or any disturbed soil as a result of the excavation process) at the bottom of the shaft should be neglected for passive resistance. 4.3.2 Thrust Block Resistance Thrust blocks will likely be used to provide the reaction for the main jacks when pushing the pipe forward. Thrust blocks for this project should be designed using an allowable passive resistance of 185 psf This includes a factor of safety of 2. This factor of safety is used to avoid large strains that are required to develop the maximum passive resistance and because of safety issues associated with the large jacking forces that are normally applied. Large movements of the thrust wall are not desirable for pipe jacking because the movements are usually not uniform, and it becomes difficult to maintain the thrust wall perpendicular to the pipe alignment. If the thrust wall does not remain square, the force applied to the pipe may not be uniform, resulting in eccentric loading which could damage the pipe. 4-5 May 3,1996 954044NXKENTRPT3.DOC Woodward-Clyde 4.3.3 Groundwater Control .� Groundwater control will be required for the jacking and receiving pits. Interlocking sheetpiles can be used to control groundwater by providing a groundwater cutoff. Flow through the base of the pit would have to be controlled with a sump system. Groundwater wells or well points can also be used to control groundwater. Localized groundwater control such as dewatering wells, well points, chemical grouting, or jet grouting to prevent inflows and loss of ground may be required at the jacking and receiving pits when breaking out of or into shafts due to the saturated sand which is present in the area where the shoring system is to be breached. The need for groundwater control when breaking into or out of shafts will depend on the elevation of the groundwater at the time of construction and the type of groundwater control used by the contractor to keep the jacking and receiving pits dry. Contract documents should include requirements that the contractor submit details for design of the shoring system, dewatering methods, and jacking methods. Shoring and dewatering designs should be performed by a licensed engineer. 4.4 SURFACE SETTLEMENT FROM TUNNELING Even with the use of proper tunnel equipment and construction methods, some surface settlement is inevitable due to unavoidable loss of ground at the tunnel face and possibly from construction dewatering. 4.4.1 Settlement from Loss-of-Ground Use of appropriate tunneling equipment and construction methods will minimize loss-of- ground, although some minor ground losses usually occur. Empirical methods have been developed for estimating the amount of surface settlement due to soft ground tunneling from the study of observed settlements on past projects (Peck 1969; Cording and Hansmire 1975). Typically the settlement pattern that develops above a soft ground tunnel is a trough-shaped " depression resembling an inverted normal probability (bell shaped) curve with the maximum settlement occurring above the tunnel centerline (Peck 1969). For a 60-inch diameter tunnel excavated at a depth of about 20 to 25 feet, the estimated maximum ground surface settlement which will occur above the tunnel centerline (due to tunneling only, not dewatering) would be as much as 2 inches, assuming that proper tunnel procedures are implemented and positive groundwater control is provided during construction. It is assumed with this estimate that the amount of overcut for the contractor's " tunneling equipment does not exceed 2 inches. 954044NA`KENTRPT3.DOC 4-6 Mav 3, 1996 Woodward-Clyde In this discussion of settlement, it is assumed that uncontrolled loss-of-ground from flowing, running, or raveling sands does not occur. If uncontrolled loss-of-ground were allowed to occur, sinkholes could result. These features can have dimensions that are tens of feet in width and several feet or more in depth. They often occur suddenly when voids that have developed with time collapse. Such occurrences can be avoided by a contractor if good tunneling practices, consistent with soil and groundwater conditions at the site, are followed. It is recommended that a monitoring program be implemented during construction to check for settlement due to tunneling. The contractor should be responsible for repairing any damage resulting from tunneling or other construction operations if settlements exceed design criteria given in the specifications. 4.4.2 Settlement from Dewatering Dewatering can result in settlement by increased loading on soil layers from lowering of groundwater elevations. This type of settlement is most prevalent where fine-grained soil -" occurs. While fine-grained soil along the alignment was limited to relatively thin layers of silty materials, the possibility of thicker deposits of fine-grained soil below the deepest depths of w the borings drilled during the tunnel exploration program cannot be ruled out. If dewatering is utilized along the alignment, a detailed evaluation of dewatering requirements _ and potential settlement should be performed by the contractor prior to construction. The evaluation is best handled by the contractor since the size, type, and location of dewatering wells will determine the location and magnitude of settlement. As with settlement from loss of -" ground, it is normally desirable to monitor settlement from dewatering by establishing ground surface elevations in proximity to dewatering operations before dewatering is initiated. During the dewatering program, elevations should be monitored on a regular basis to determine if settlement is within criteria given in the project specifications. 4.5 ALTERNATIVE TUNNELING METHODS A number of tunnel methods are available for installing casing of the size required for this project. The two primary alternatives involve pipe jacking and pressurized face microtunneling. Some of the key advantages and disadvantages relative to use of the methods on the Mill Creek/SR 167 drainage tunnel project are briefly summarized below. 4.5.1 Pipe Jacking a Two pipe jacking methods can be considered for these ground conditions: 1) boring-and- jacking methods, and 2) pipe jacking with shield methods. Flowing and running ground conditions are anticipated along the alignment. As a result, if the contractor selects either of 954044NA1KENTRPT3.DOC 4-7 May 3. 1996 Woodward-Clyde these methods of tunneling, procedures for preventing loss of ground will have to be developed. In view of the potential consequences to SR 167, either from settlement or under worse-case conditions, sinkholes, the contractor's methods for dealing with ground loss should be a mandatory submittal. Bore-and-Jack For standard horizontal bore-and-jack methods, the face would have to be controlled by keeping the augers pushed firmly against the ground. This makes it difficult to monitor line- and-grade because the augers cannot be retracted without some loss of ground. For flowing ground conditions, bore-and jack methods could involve serious loss-of-ground if augers are withdrawn to remove an obstruction or to adjust steering, or if the augers are allowed to "spin" within the pipe without forward progress of the augers. For these reasons dewatering appears to be necessary for this approach to be feasible. While bore-and-jack methods are likely to be less expensive than other pipe jacking methods, �. the potential for problems with line-and-grade, loss-of-ground, and obstructions indicates that this method is not particularly well-suited for the Mill Creek drainage tunnel project. Jacking With Shield .. Pipe jacking with a shield is a more appropriate method for the anticipated subsurface conditions than bore-and-jack methods because loss of ground can be better controlled at the face. Groundwater control will be required to prevent flowing ground conditions from developing and significant loss-of-ground. The shield used with this method normally has steering jacks to allow more accurate line-and-grade control than with bore-and-jack methods. W. If pipe jacking with a shield is utilized, a full circle tunnel shield should be provided ahead of the lead pipe segment. The shield should have steering jacks so that line-and-grade ... adjustments can be made to maintain the installation within the required tolerances. The shield should be capable of preventing loss-of-ground at the tunnel heading at all times. This can be achieved through the use of either a closed face cutterhead machine with flood doors, or with an open-faced shield equipped with breast tables, breast jacks and/or sand shelves. The equipment should be able to fully support the face to prevent loss-of-ground during excavation and shutdown periods. This type of system could accommodate access to the face to remove an obstruction such as a buried tree. ^- 4.5.2 Pressurized Face Microtunneling A tunneling shield with a pressurized face capability is ideal for projects where flowing ground conditions occur because it can control flowing ground conditions without the need for 954044N.a1KENTRPT3.DOC 4-8 May 3,1996 Woodward-Clyde dewatering along the tunnel alignment. Use of pressurized face equipment also minimizes surface settlement and potential damage to adjacent structures and utilities that could result from dewatering or loss of ground during tunneling. The primary disadvantage of pressurized face microtunneling is the higher cost. There are a number of issues that will have to be considered if pressurized face microtunneling methods are used. Because of the proximity to Mill Creek, it will be important to closely monitor and control the pressure applied to the tunnel face to avoid fracturing the ground and -the discharge of slurry into the creek, fields, landscaped area, and onto the ground surface. In general this can be accomplished by limiting the pressure to less than the overburden pressure. _— Localized dewatering, as discussed in Section 4.2, and launching seals will be required for groundwater control and to prevent leakage of bentonite at the jacking and receiving pits. Potential obstructions such as trees and wood debris which were encountered in all of the borings could cause a microtunneling machine to become stuck or slurry lines to become plugged. The possibility of encountering obstructions will have to considered in selecting the — type of cutterhead for this equipment. 4.6 TUNNEL CONSTRUCTION CONSIDERATIONS This section summarizes important tunnel design and construction considerations that should _ be addressed in the preparation of project plans and specifications. 1. The tunnel should be constructed utilizing pipe jacking or microtunneling equipment that is capable of controlling running and flowing ground conditions and minimizing loss-of-ground. The specifications should require positive groundwater control measures to be implemented in advance of tunneling. A description of the contractor's approach to controlling groundwater and preventing loss-of-ground should be submitted. This approach should specifically address the manner in which the contractor will deal with flowing ground.. It should be prepared by someone with experience in soft ground tunneling where flowing ground conditions are prevalent. The equipment should also be capable of removing or excavating trees or other debris without loss-of-ground. 2. If dewatering methods are allowed by WSDOT and if the contractor's tunneling method involves groundwater control by dewatering, a detailed evaluation of dewatering requirements and potential settlement should be performed by the contractor. The specifications should require that the contractor use a licensed engineer experienced in design of dewatering systems to complete the design. The contractor's submittal should include an estimate of roadway settlement resulting from 954044NA1KENTRPT3.DOC 4-9 Nlav 3. 1996 Woodward-Clyde the dewatering system operation. The wells should be properly designed and developed to prevent pumping of fines from the formation. 3. Shaft excavations for jacking and receiving pits should be supported in accordance with recommendations presented in Section 4.5.1. Specifications should require that the contractor submit computations showing how the sizes of structural members meet these requirements. 4. Groundwater control should be provided during shaft excavations and when breaking out of the jacking pit and breaking into the receiving pit to prevent loss of ground and -- surface settlement. Launching seals or other methods should be used to prevent loss of ground when breaking out of the jacking pit. Specifications should require that the contractor submit plans for accomplishing these groundwater control and loss-of- ground requirements. 5. When tunneling operations are stopped, the tunnel face should be firmly supported by breasting or by closing the doors on the closed-face shield to prevent loss-of-ground. 6. The contractor should submit shop drawings and design calculations demonstrating that the steel casing is capable of withstanding all anticipated loading conditions including jacking and handling stresses. 7. If slurry microtunneling equipment is utilized, the slurry pressure applied at the tunnel face should be carefully controlled to prevent fracturing of the ground and discharge of slurry into the creek or on to the ground surface. S. In order to reduce friction, pipe jacking operations should include a bentonite lubrication system in the annular space between the ground and the casing. 9. Tunneling should proceed on a continuous 24-hour per day basis until all the casing for the crossing has been installed. Continuous operations will minimize the time to complete the crossing and also help minimize jacking forces and prevent freeze-up of �- the pipe. 10. Tunneling equipment should have a steering system capable of achieving the specified line-and-grade tolerances. Line-and-grade should be monitored during tunneling. Measurements should be obtained frequently (every 2 feet) and the necessary steering adjustments completed to maintain the pipeline installation within the specified tolerances. 4-10 flay 3, 1996 954044NA`,KENTRPT3.DOC Woodward-Clyde 11. Tunnel spoil and slurry resulting from tunnel excavation should be removed from the site and should be properly disposed of at an acceptable facility. -- 12. The City should take preconstruction and postconstruction photographic surveys of SR 167 to document existing conditions prior to construction. This reconnaissance survey will serve as an aid in evaluating possible damage due to settlement. 13 A system of vertical control points should be established to monitor surface settlement during construction. Elevations of the control points should be surveyed frequently during construction in accordance with specified intervals. Control points should be spaced every 10 feet along the tunnel alignment's centerline and offset 10 and 20 feet on either side where possible. Control points located within the highway right-of-way should be located as approved by WSDOT. Monitoring should consist of measuring — the elevation of each of the control points with respect to a benchmark to an accuracy Of f0.01 foot. 14. The contractor should be required to submit the following for review: general tunnel work plan and schedule; tunneling equipment details; groundwater control provisions; jacking system details; estimated maximum jacking forces; line-and-grade control and steering procedures; steel casing shop drawings; thrust block design; bentonite injection system;jacking and receiving pit shoring design and shop drawings; and spoil -- disposal details. 15. The contractors bidding on this project should be required to submit qualifications statements (with references) indicating successful completion of at least two prior tunneling projects using the same construction and groundwater control methods which are proposed for this project. 9 54044NA\KENTRPT3.DOC 4-11 Mav 3, 1996 Woodward-Clyde 5.0 UNCERTAINTY AND LIMITATIONS The conclusions, recommendations and opinions in this report herein are (1) based upon our evaluation and interpretation of the findings of our field exploration and laboratory testing programs, (2) our interpolation of subsurface conditions between borings, (3) our understanding of the project site and tunnel geometry, as described herein, and (4) our assumption that sufficient geotechnical observation and monitoring will be provided during " construction.

CATEGORIES OF GROUND BEHAVIOR FOR SOFT GROUND TUNNELS (Modified After Terzaghi, 1950) Firm Ground. A heading may be advanced several feet or more without immediate support. Hard clays and cemented sand or gravel generally fall into this category. Raveling Ground. After excavation, material above the tunnel or in the upper part of the working face tends to flake off and fall into the heading. Slightly cohesive sands, silts, and fine sands gaining their strength from apparent cohesion typically exhibit this type of behavior. Stiff fissured clays may be raveling materials also. In fast raveling ground the process starts within a few minutes, otherwise the ground is slow raveling. �.. Running Ground. Cohesionless, dry soils run from any unsupported vertical face until a stable slope forms at the natural angle of repose (i.e., approximately 30 degrees to 35 degrees). Running ground consists of dry. cohesionless materials, such as clean loose sand or gravel. �— Flowing Ground. If seepage develops at the working face, raveling or running ground is transformed to flowing ground, which advances like a viscous fluid into the heading. Silt, sand, or gravel below the water table without a high enough clay content to develop significant cohesion will be flowing-type soils. Swelling Ground. A condition where the ground absorbs water, increases in volume and expands slowly into the tunnel. This may occur in highly overconsolidated clays that exhibit high volume change characteristics upon wetting. Squeezing Ground. Squeezing ground conditions are analogous to plastic flow, and the soil is observed to advance slowly into the tunnel excavation without any signs of fracturing. Squeezing occurs without an increase in the water content or a volume change in the soil and is governed by the soil strength in comparison -- to the overburden pressure. Squeezing ground may include soft to medium stiff or stiff clays depending of the overburden pressure at the tunnel depth.

The purpose of the borings was to obtain subsurface information necessary to evaluate tunneling and excavation conditions as well as other pertinent information necessary for performing engineering analyses and formulation of geotechnical design recommendations for the proposed tunnel project. The borings were drilled near the jacking pit (BH-3), receiving pit (BH-1), and near the tunnel midpoint (BH-2). The boring locations are shown on the Site and Exploration Plan (Figure 1). The borings were drilled on three separate days, by three different drillers, due to access W.. permit acquisition delays, driller availability, and access constraints. Boring BH-2 was drilled on March 4, 1996, by Gregory Drilling of Redmond, Washington, using a truck-mounted CME-85 drill rig (equipped with a trip-release hammer) advancing 8-inch outside diameter, continuous flight, hollow stem augers and 3-5/8 inch tricone with mud rotary techniques. Boring BH-3 was drilled on March 29, 1996, by Cascade Drilling of Woodinville, Washington, using a truck-mounted CME-75 high torque drill rig (equipped with rope and cathead) advancing 3-5/8 inch diameter tricone with mud rotary techniques. Boring BH-1 was drilled on April 8, 1996, by Pacific Testing Laboratory of Seattle, Washington, using a tracked Nodwell Mobile B-61 drill rig (equipped with rope and cathead) advancing 9-inch outside diameter, continuous flight, hollow stem augers. Borings BH-1, BH-2, and BH-3 were advanced to 31'/2, 46'/z, and 31'/z feet below the ground surface, respectively. All three drillers were subcontracted to WCC and the borings were advanced under the full-time observation of a geotechnical engineer from WCC. �. The soils encountered in the test borings were typically sampled at 21/2 to 5-foot vertical intervals with a standard split spoon sampler or a California split-spoon sampler. Standard �- Penetration Test (SPT) sampling was performed using a 2-inch outside diameter split-spoon sampler driven with a standard 140-pound hammer in accordance with ASTM D 1586. During the test, a sample is obtained by driving the sampler 18 inches into the soil with a hammer free-falling 30 inches. The number of blows required for each 6 inches of penetration is recorded. The Standard Penetration Resistance ("N-value") of the soil is calculated as the number of blows required for the final 12 inches of penetration. This resistance, or N-value, provides a measure of the relative density of granular soils and the relative consistency of cohesive soils. If the high penetration resistance encountered in the very dense soils precluded driving the total 18-inch sample interval, the penetration resistance for the partial penetration tifay 3, 1996 954044NA\KENTRPT3.DOC A-1 ar Woodward-Clyde is entered on logs as follows: if the penetration is greater than 6 inches and less than 18 inches, then the number of blows is recorded over the number of inches driven; 30 blows for 6 inches and 50 for 3 inches, for instance, would be recorded as 80/9". The blow counts are shown on the boring logs at the respective sample depths. The Standard Penetration Test is a useful quantitative tool from which soil density/consistency was evaluated. A 3-1/2 inch O.D. California sampler, lined with 6-inch long stainless steel tubes, was -. intermittently used in an attempt to obtain less disturbed samples for unit weight testing. This sampling technique proved to be difficult due to the flowing conditions of the sand. The soils encountered during boring operations were visually classified in the field by the engineer in general accordance with the Unified Soil Classification System (USCS). The soil samples were collected by WCC's engineer, placed in plastic bags, and transported for observation and laboratory testing. The field classifications were checked in our office after laboratory testing had been completed. In addition, pertinent information including soil sample depths, stratigraphy, and groundwater occurrence were recorded. The drilling operation was also monitored for indication of -- various drilling conditions, such as hard drilling and soft drilling. Sample rods were monitored for indications of groundwater. Groundwater was measured in all three borings while hollow stem auger techniques were used. Drilling stopped for a short time until water levels appeared stabilized and then they were measured by taping or by a water sounding instrument. /Summary boring logs are presented on Figures A-2 through A-4. A key to the symbols and terms used on the logs are included on Figure A-l. The stratigraphic contacts shown on the individual boring logs represent the approximate boundaries between soil types. The actual transitions between soil units may be more gradual or abrupt. The soil and groundwater conditions depicted are only for the specific dates and locations reported, and therefore, are not necessarily representative of other locations and times. 954044N A\KENTRPT3.DOC A-2 Mav 3,1996 Project: Mill Creek / SR 167 Drainage Tunnel Key to Log of Boring Project Location: Kent, Washington Project Number: 954044NA Sheet 1 of 2 SAMPLES c o 0 c: > M E W z MATERIAL DESCRIPTION Nin REMARKS/ ,.. >" CL 0) > r o OTHER TESTS LU ��' > M aW00i o mrn � o 0CN 0 I— Z a Cr co 16 J 1 3 U o zt Dense, moist, brown, SILTY SAND(SM). , [solid line denotes observed contact between strata or abrupt change _In soil type] ------------------------ ----------- a ___ [dashed line denotes Inferred contact between strata or gradational change in soil type] Hard drilling at 5 ft. 1 90 34 California sample; driven sample collected in 3-inch-OD 5 r.. split-barrel sampler. 12 38 LL=27, PI 2 85 37 Standard Penetration Test (SPT)sample;driven sample LIC=1440 collected in 2-inch-OD split-spoon sampler. i 1 2 3 4 5 6 7 ® 9❑ 10 11 ❑ ❑ ❑ ❑ ❑i ❑ ❑ -- COLUMN DESCRIPTIONS 1❑ Elevation: Elevation (in feet, datum unknown); approximated from client's site plan. .� 2❑ Depth: Distance (in feet) below the ground surface. 3❑ Sample Type: Type of soil sample collected at depth interval depicted; symbols explained above. ® Sample Number: Sample identification number. .�. 5❑ Percent Recovery: Percentage of sample recovered for given sample interval; blank if not recorded. © Sample Blows/foot: Number of blows required to advance driven sampler 1 foot, or distance indicated, using a 140-lb hammer with a 30-inch drop.

The tests were performed in general accordance with test methods of the American Society for Testing and Materials (ASTM) or other applicable procedures. Selected soil samples were tested for in-place moisture content, percent passing No. 200 sieve, and grain size distribution. The results of the laboratory tests are presented on Table B-1, and Figures B-1 and B-2. The moisture content test results and percent passing the No. 200 sieve are also presented on the boring logs in Appendix A. Water Content Determinations Water contents were determined in general accordance with ASTM D 2216 for several of the samples obtained from the borings. The results of these tests are presented on the boring logs at the respective sample depth. Percent Passing U.S. No. 200 Sieve Selected samples were "washed" through the No. 200 mesh sieve to determine the relative percentages of coarse and fine-grained particles in the soil. The percent passing value represents the percentage by weight of the sample finer than the U.S. No. 200 sieve. These tests were conducted to verify field descriptions and to determine the fines content for ` analyses purposes. The tests were conducted in accordance with ASTM D 1140, and the results are shown on Table B-1 and on the boring logs at the respective sample depth. Table B-1.

The wet sieve analysis method was used to determine the percentage of soil greater than the U.S. No. 200 mesh sieve. The results of the grain size analyses were plotted, classified in general accordance with USCS, and are presented on Figures B-1 and B-2.
