The Weekly Look-Ahead Schedule shall include the description, duration and sequence of work, along with the planned hours of work. This schedule may be a network schedule, bar chart, or other standard schedule format. The Weekly Look-Ahead Schedule shall be submitted to the Engineer by the midpoint of the week preceding the scheduled work or some other mutually agreed upon submittal time. 1-08.3(3) Schedule Updates The Engineer may request a Schedule Update when any of the following events occur: 1. The project has experienced a change that affects the critical path. 2. The sequence of work is changed from that in the approved schedule. 3. The project is significantly delayed. 4. Upon receiving an extension of contract time. WSDOT Amendments 5 The Contractor shall submit five copies of a Type A or Type B Schedule Update within 15 ' calendar days of receiving a written request, or when an update is required by any other provision of the contract. A"significant"delay in time is defined as 10 working days or 10 , percent of the original contract time,whichever is greater. In addition to the other requirements of this Section, Schedule Updates shall reflect the ' following information: 1. The actual duration and sequence of as-constructed work activities, including ' changed work. 2. Approved time extensions. 3. Any construction delays or other conditions that affect the progress of the work. ' 4. Any modifications to the as-planned sequence or duration of remaining activities. ' 5.

Payment of 80 percent of the lump sum price will be made upon approval of the Progress ' Schedule. Payment will be increased to 100 percent of the lump sum price upon completion of 80 percent of the original total contract award amount. All costs for providing Type A Progress Schedules and Weekly Look-Ahead Schedules are considered incidental to other items of work in the contract. No payment will be made for Schedule Updates that are required due to the Contractors operations. Schedule Updates required by events that are attributed to the actions of the } Contracting Agency will be paid for in accordance with Section 1-09.4. 1-08.4 Prosecution of Work The first sentence is revised to read: WSDOT Amendments 6 The Contractor shall begin work within 21 calendar days from the date of execution of the contract by the Contracting Agency,unless otherwise approved in writing. 1-08.5 Time for Completion This section is revised to read: r The Contractor shall complete all physical contract work within the number of"working days" stated in the Contract Provisions or as extended by the Engineer in accordance with Section 1- 08.8. Every day will be counted as a "working day' unless it is a nonworking day or an Engineer determined unworkable day. A nonworking day is defined as a Saturday, a Sunday, a whole or half day on which the contract specifically prohibits work on the critical path of the Contractor's approved progress schedule, or one of these holidays: January 1, the third Monday 0° of January, the third Monday of February, Memorial Day, July 4, Labor Day, November 11, Thanksgiving Day, the day after Thanksgiving, and Christmas Day. When any of these holidays fall on a Sunday, the following Monday shall be counted a nonworking day. When the holiday falls on a Saturday, the preceding Friday shall be counted a nonworking day. The days between December 25 and January 1 will be classified as nonworking days. rr An unworkable day is defined as a half or whole day the Engineer declares to be unworkable because of weather or conditions caused by the weather that prevents satisfactory and timely performance of the work shown on the critical path of the Contractor's approved progress schedule. Other conditions beyond the control of the Contractor may qualify for an extension of time in accordance with Section 1-08.8. Contract time shall begin on the first working day following the 21 st calendar day after the date the Contracting Agency executes the contract. If the Contractor starts work on the project at an earlier date, then contract time shall begin on the first working day when onsite work begins. The contract provisions may specify another starting date for contract time, in which case, time will begin on the starting date specified. Each working day shall be charged to the contract as it occurs, until the contract work is physically complete. If substantial completion has been granted and all the authorized working days have been used, charging of working days will cease. Each week the Engineer will provide the Contractor a statement that shows the number of working days: (1) charged to the contract the week before; (2) specified for the physical completion of the contract; and (3) remaining for the physical completion of the contract. The statement will also show the nonworking days and any half or whole day the Engineer declares as unworkable. Within 10 calendar days after the date of each statement, the Contractor shall file a written protest of any alleged discrepancies in it. To be considered by the Engineer, the protest shall be in sufficient detail to enable the Engineer to ascertain the basis and amount of time disputed. By not filing such detailed protest in that period,the Contractor shall be deemed as having accepted the statement as correct. The Engineer will give the Contractor written notice of the physical completion date for all work the contract requires. That date shall constitute the physical completion date of the contract, but shall not imply the Secretary's acceptance of the work or the contract. The Engineer will give the Contractor written notice of the completion date of the contract after all the Contractor's obligations under the contract have been performed by the Contractor. The ' following events must occur before the Completion Date can be established: 1. The physical work on the project must be complete; and 1 WSDOT Amendments 7 2. The Contractor must furnish all documentation required by the contract and required by law, to allow the Contracting Agency to process final acceptance of the contract. ' The following documents must be received by the Project Engineer prior to establishing a completion date: a. Certified Payrolls(Federal-aid Projects) b. Material Acceptance Certification Documents c. Annual Report of Amounts Paid as MBE/WBE Participants or Quarterly Report of Amounts Credited as DBE Participation, as required by the Contract Provisions. d. FHWA 47(Federal-aid Projects) e. Final Contract Voucher Certification , 1-08.8 Extensions of Time Section 1-08.8 is revised to read: ' The Contractor shall submit any requests for time extensions to the Engineer in writing no later than 10 working days after the delay occurs. The requests for time extension shall be limited to the affect on the critical path of the Contractor's approved schedule attributable to the change or event giving rise to the request. To be considered by the Engineer, the request shall be in sufficient detail (as determined by the Engineer) to enable the Engineer to ascertain the basis and amount of the time requested. The request shall include an updated schedule that supports the request and demonstrates that the change or event: (1)had a specific impact on the critical path, and except in cases of concurrent delay, was the sole cause of such impact, and (2) could not have been avoided by resequencing • of the work or by using other reasonable alternatives. If a request combined with previous extension requests, equals 20 percent or more of the original contract time then the Contractor's letter of request must bear consent of Surety. In evaluating any request, the Engineer will �► consider how well the Contractor used the time from contract execution up to the point of the delay and the effect the delay has on any completion times included in the special provisions. The Engineer will evaluate and respond within 15 calendar days of receiving the request. The authorized time for physical completion will be extended for a period equal to the time the Engineer determines the work was delayed because of: 1. Adverse weather causing the time requested to be unworkable, provided that the Engineer had not already declared the time to be unworkable and the Contractor has filed a written protest according to Section 1-08.5. 2. Any action, neglect, or default of the Contracting Agency, its officers, or employees, or ■r of any other contractor employed by the Contracting Agency. I Fire or other casualty for which the Contractor is not responsible. 4. Strikes. , 5. Any other conditions for which these Specifications permit time extensions such as: a. In Section 1-04.4 if a change increases the time to do any of the work including unchanged work. as ■i WSDOT Amendments 8 b. In Section 1-04.5 if increased time is part of a protest that is found to be a valid protest. c. In Section 1-04.7 if a changed condition is determined to exist that caused a delay in completing the contract. w. d. In Section 1-05.3 if the Contracting Agency does not approve properly prepared and acceptable drawings within 30 calendar days. e. In Section 1-07.13 if the performance of the work is delayed as a result of damage by others. f. In Section 1-07.17 if the removal or the relocation of any utility by forces other than the Contractor caused a delay. g. In Section 1-07.24 if a delay results from all the right of way necessary for the construction not being purchased and the special provisions does not make specific provisions regarding unpurchased right of way. h. In Section 1-08.6 if the performance of the work is suspended, delayed, or interrupted for an unreasonable period of time that proves to be the r responsibility of the Contracting Agency. i. In Section 1-09.11 if a dispute or claim also involves a delay in completing the contract and the dispute or claim proves to be valid. j. In Section 1-09.6 for work performed on a force account basis. 6. If the actual quantity of work performed for a bid item was more than the original plan quantity and increased the duration of a critical activity. Extensions of time will be limited to only that quantity exceeding the original plan quantity. 7. Exceptional causes not specifically identified in items 1 through 6, provided the request letter proves the Contractor had no control over the cause of the delay and could have done nothing to avoid or shorten it. Working days added to the contract by time extensions, when time has overran, shall only apply to days on which liquidated damages or direct engineering have been charged, such as the following: If substantial completion has been granted prior to all of the authorized working days being used, then the number of days in the time extension will eliminate an equal number of days on which direct engineering charges have accrued. If the substantial completion date is established after all of the authorized working days have been used, then the number of days in the time extension will eliminate an equal number of days on which liquidated damages or direct engineering charges have accrued. The Engineer will not allow a time extension for any cause listed above if it resulted from the Contractor's default, collusion,action or inaction, or failure to comply with the contract. The Contracting Agency considers the time specified in the special provisions as sufficient to do all the work. For this reason, the Contracting Agency will not grant a time extension for: WSDOT Amendments 9 • Failure to obtain all materials and workers unless the failure was the result of , exceptional causes as provided above in subsection 7; • Changes, protests, increased quantities, or changed conditions (Section 1-04) that do , not delay the completion of the contract or prove to be an invalid or inappropriate time extension request; ' • Delays caused by nonapproval of drawings or plans as provided in Section 1-05.3; • Rejection of faulty or inappropriate equipment as provided in Section 1-05.9; • Correction of thickness deficiency as provided in Section 5-05.5(1)B. The Engineer will determine whether the time extension should be granted, the reasons for the extension, and the duration of the extension, if any. Such deternunation will be final as provided in Section 1-05.1. , SECTION 1-09,MEASUREMENT AND PAYMENT December 4,2006 1-09.6 Force Account The last paragraph under "3.

The blasting plan shall contain the full details of the drilling and blasting patterns and controls the Contractor proposes to use for both the controlled and production blasting. The blasting plan submittal is required for all blasting operations and shall contain the following minimum information: a) Station limits of proposed shot. b) Plan and section views of proposed drill pattern including free face, burden, blast hole spacing, blast hole diameter, blast hole angles, lift height, and subdrill depth. c) Loading diagram showing type and amount of explosives, primers, initiators, and location and depth of stemming. d) Initiation sequence of blast holes including delay times and delay system. e) Manufacturer's data sheets for all explosives, primers, and initiators to be employed. Review of the blasting plan by the Engineer shall not relieve the Contractor of the responsibility for the accuracy and adequacy of the plan when implemented in the field. When blasting to establish slopes '/2 to 1 or steeper, and more than 10 feet high, the Contractor shall use controlled blasting. The Engineer may require the Contractor to use controlled blasting to form the faces of other slopes, even if the slopes could be formed by 1 nonblasting methods. WSDOT Amendments Controlled blasting refers to the controlled use of explosives and blasting accessories in ' carefully spaced and aligned drill holes to provide a free surface or shear plane in the rock along the specified backslope. Controlled blasting techniques covered by this specification ' include presplitting and cushion blasting. In addition to the blasting plan submittal, when using controlled blasting the Contractor shall: ' a) Prior to commencing full-scale blasting operations, the Contractor shall demonstrate the adequacy of the proposed blast plan by drilling, blasting, and excavating short test sections, up to 100 feet in length, to determine which combination of method, hole spacing, and charge works best. When field conditions warrant, the Contractor may be ordered to use test section lengths less than 100 feet. Unless otherwise approved by the Engineer, the Contractor shall begin the tests , with the controlled blast holes spaced 30-inches apart, then adjust if needed, until the Engineer approves the spacing to be used for full-scale blasting operations. b) The Contractor shall completely remove all overburden soil and loose or , decomposed rock along the top of the excavation for a distance of at least 30 feet beyond the end of the production hole drilling limits, or to the end of the cut, before drilling the presplitting holes. c) The controlled blast holes shall be not less than 21/2 inches nor more than 3 inches in diameter. d) The Contractor shall control drilling operations by the use of the proper equipment and technique to ensure that no hole shall deviate from the plane of the planned slope by more than 9 inches either parallel or normal to the slope. Drill holes exceeding these limits shall not be paid for unless satisfactory slopes are being obtained. e) Controlled blast holes shall extend a minimum of 30 feet beyond the limits of the production holes to be detonated, or to the end of the cut as applicable. f) The length of controlled blast holes for any individual lift shall not exceed 20 feet unless the Contractor can demonstrate to the Engineer the ability to stay within ' the above tolerances and produce a uniform slope. If greater than 5 percent of the presplit holes are misaligned in any one lift, the Contractor shall reduce the height of the lifts until the 9-inch alignment tolerance is met. Upon satisfactory demonstration, the length of holes may be increased to a maximum of 60 feet , with written approval of the Engineer. g) When the cut height requires more than one lift, a maximum 2-foot offset between lifts will be permitted to allow for drill equipment clearances.- The Contractor shall begin the control blast hole drilling at a point that will allow for necessary offsets and shall adjust, at the start of lower lifts, to compensate for any drift that may have occurred in the upper lifts. h) Before placing charges, the Contractor shall determine that the hole is free of ' obstructions for its entire depth. All necessary precautions shall be exercised so WSDOT Amendments 12 , • that the placing of the charges will not cause caving of material from the walls of the holes. r i) The maximum diameter of explosives used in presplit holes shall not be greater than X12 the diameter of the presplit hole. j) Only standard explosives manufactured especially for controlled blasting shall be used in controlled blast holes, unless otherwise approved by the Engineer. Bulk ammonium nitrate and fuel oil (ANFO) shall not be allowed to be loaded in the r presplit holes. k) If fractional portions of standard explosive cartridges are used, they shall be firmly affixed to the detonating cord in a manner that the cartridges will not slip i down the detonating cord nor bridge across the hole. Spacing of fractional cartridges along the length of the detonating cord shall not exceed 30 inches center to center and shall be adjusted to give the desired results. r 1) Continuous column cartridge type of explosives used with detonating cord shall be assembled and affixed to the detonating cord in accordance with the explosive manufacturer's instructions, a copy of which shall be furiiished to the Engineer. m) The bottom charge of a presplit hole may be larger than the line charges but shall r. not be large enough to cause overbreak. The top charge of the presplitting hole shall be placed far enough below the collar, and reduced sufficiently, to avoid overbreaking and heaving. n) The upper portion of all presplit holes, from the top most charge to the hole collar, shall be stemmed. Stemming materials shall be sand or other dry angular material, all of which passes a 3/8-inch sieve. o) If presplitting is specified, the detonation of these holes shall be fired first. p) If cushion blasting is specified, the detonation of these holes shall be fired last on an instantaneous delay after all other blasting has taken place in the excavation. q) Production blast holes shall not be drilled closer than 6 feet to the controlled blast line, unless approved by the Engineer. The bottom of the production holes shall ' not be lower than the bottom of the controlled blast holes. Production holes shall not exceed 6 inches in diameter, unless approved by the Engineer.

' Samples will be randomly taken by the Engineer at the job site to confirm that the geosynthetic meets the property values specified. Approval will be based on testing of samples from each lot. A"lot" shall be defined for the purposes of this specification as all geosynthetic rolls within the consignment (i.e., all rolls sent the project site) that were produced by the same manufacturer during a continuous period of production at the same manufacturing plant and have the same product name. After the samples have arrived at the State Materials Laboratory in Tumwater, a maximum of 14 calendar days will be required for this testing. If the results of the testing show that a geosynthetic lot, as defined, does not meet the properties required for the specified use as indicated in Tables 1 through 8 in Section 9- 33.2, and additional tables as specified in the Special Provisions, the roll or rolls which were sampled will be rejected.

(Kleinfelder) for the proposed Sanitary Sewer Interceptor pipeline between SW Langston Road (west end) and 84th Avenue South (east end) in the Skyway neighborhood of King County, Washington, just west of the City of Renton. The project location and general interceptor layout are shown on the enclosed Vicinity Map (Figure 1) and Site and Exploration Plans (Figures 2, 3, and 4). The purpose of our study was to evaluate the subsurface conditions along the project alignment and provide geotechnical recommendations for design and construction of the proposed sewer pipelines. 1.2 PROJECT DESCRIPTION We understand that the City of Renton is planning to install about 1,780 linear feet of gravity sewer main lines to replace the Earlington Lift Station, located at the west end of the alignment, near proposed Man Hole (MH) No. 14 on SW Langston Road. The majority of the sewer alignment will traverse across existing single-family house lots and gravel-surfaced access roads. Most of the pipeline will be installed using standard open trenching construction. However, we understand that about 240 feet of the line (between MH No. 11 and 12 near the western end) will be installed using trenchless installation technology. As proposed, the project will involve construction of main gravity pipelines buried from about 6 to 18 feet below the exiting ground surface. The lines will drain from the west end (SW Langston Rd) toward the east end (84th Avenue South). 1.3 SCOPE OF SERVICES AND AUTHORIZATION The work was performed in accordance with the scope of work described in our Proposal for Geotechnical Engineering Services, dated March 21, 2007. Written authorization and a signed consultant Agreement for the work was provided on March 23, 2007. 82991/SEA7R080.doc Page 1 of 23 July 11,2007 Copyright 2007 Kleinfelder I k'q KLEINFELDER 2.0 FIELD AND LABORATORY PROGRAMS �r 2.1 GENERAL We explored surface and subsurface conditions at the project site during a series of site visits during May and June, 2007. Our exploration and testing program included the following elements: . A visual surface reconnaissance of th e ,site; Nine hollow-stem auger borings with Standard Penetration Tests, advanced at strategic locations along the proposed sewer line alignment; Five Monitoring Wells installed at selected boring locations and monitored over the course of one month following installation; ; . Six Grain Size Analyses (Sieves), performed on representative soil samples obtained from the site soils; . Six Moisture Content determinations, performed on representative soil samples obtained from the site soils; and A review of published geologic and seismologic maps and literature. The specific number, locations, and depths of our explorations were selected in relation to the existing and proposed site features, under the constraints of surface access, underground utility conflicts, and budget considerations. The elevation and relative location of the borings and the monitoring wells were located and plotted on the site plan by our field representative. The locations of all explorations were obtained by measuring from existing features and scaling these measurements onto a site plan supplied to us. We then estimated the surface elevation at these locations by informal field surveying methods and by interpolating between contour lines shown on the topographic site plan. Figures 2 through 4 depict the approximate elevations and relative locations of the field explorations, which should be considered accurate only to the degree permitted by our data sources, the surveying methods used, and implied by our measuring methods. It should be realized that the explorations performed for this evaluation reveal subsurface conditions only at discrete locations across the project site and that actual conditions in other areas could vary. Furthermore, the nature and extent of any such variations would not become evident until additional explorations are performed or until construction activities have commenced. If significant variations are observed at that 82991/SEA7RO80.doc Page 2 of 23 July 11,2007 Copyright 2007 Kleinfelder KLEINFELDER time, we may need to modify our conclusions and recommendations contained in this report to reflect the actual site conditions. 2.2 FIELD EXPLORATION The borings advanced for this project extended to depths ranging from about 7 to 21 feet below the ground surface (bgs). It should be noted that the borings were generally advanced until refusal was encountered within the underlying, unweathered bedrock. Groundwater monitoring wells (piezometers) were also installed in five of the borings. The following paragraphs describe the procedures associated with the field explorations and field tests that were conducted for this project. Descriptive logs of our borings and monitoring wells (designated B-1 through B-6) are presented in Appendix A. 2.2.9 Auger Boring Procedures The exploratory borings were advanced with a hollow-stem auger on May 2 and 3, 2007, using a limited access, track-mounted drill rig operated by an independent drilling firm working under subcontract to Kleinfelder. A geotechnical engineer from our firm continuously observed the borings, logged the subsurface conditions, and collected representative soil samples. All samples were stored in sealed plastic jars and later transported to our laboratory for further visual examination and testing. After each boring was completed, the borehole was backfilled with a mixture of bentonite chips and soil cuttings, or converted to a ground water monitoring well, and the surface was patched with asphalt or concrete (where appropriate). Throughout the drilling operation, soil samples were obtained at 2%- or 5-foot depth intervals by means of the Standard Penetration Test (SPT) per ASTM:D-1586. This testing and sampling procedure consists of driving a standard 2-inch outside diameter steel split-spoon sampler 18 inches into the soil with a 140-pound hammer free-falling 30 inches. The number of blows required to drive the sampler through each 6-inch interval is counted, and the total number of blows struck during the final 12 inches is recorded as the Standard Penetration Resistance, or "SPT blow count." If a total of 50 blows is struck within any 6-inch interval, the driving is stopped and the blow count is recorded as 50 blows for the actual penetration distance. The resulting Standard Penetration Resistance values indicate the relative density of granular soils and the relative consistency of cohesive soils. 82991/SEA7R080.doc Page 3 of 23 July 11,2007 Copyright 2007 Kleinfelder ,ai ------ ---------------------------- ----- KLEINFELDER The boring logs presented in Appendix A describe the vertical sequence of soils and materials encountered in each boring, based primarily on our field classifications and supported by our subsequent laboratory examination and testing. Where a soil contact was observed to be gradational, our logs indicate the average contact depth. Where a soil type changed between sample intervals, we inferred the contact depth. Our logs also graphically indicate the blow count, sample type, sample number, and approximate depth of each soil sample obtained from the borings, as well as any laboratory tests performed on these soil samples. If any groundwater was encountered in a borehole, the approximate groundwater depth is depicted on the boring log. Groundwater depth estimates are typically based on the moisture content of soil samples, the wetted height on the drilling rods, and the water level measured in the borehole after the auger has been extracted. 2.2.2 Monitoring Well Installation Procedures The groundwater monitoring wells (piezometers) were installed by the drilling firm subcontracted to Kleinfelder. The piezometers were screened in the lower parts of the borings to monitor groundwater levels within the anticipated depths of the proposed pipe invert elevations. A geotechnical engineer or specialist from our firm continuously observed the installation of the monitoring wells. The wells were installed in general accordance with Washington State Department of Ecology (DOE) requirements. Typically, a 1 or 2-inch diameter, solid PVC pipe casing is installed to the required groundwater monitoring depth. Generally, the screened (slotted PVC) portion of the well is carefully placed within the depth interval where groundwater seepage is observed during drilling or anticipated based on soil stratification or groundwater fluctuations. The screened section of the well is backfilled with select #10 / #20 sand pack to approximately two to three feet above the screened section. The remainder of the well casing (solid PVC) is backfilled with bentonite to seal off the screened zone of the well from overlying groundwater infiltration. A minimum 5-feet of solid PVC with bentonite backfill is typically maintained at the surface above any screened well section. At the ground surface, a flush-mounted, WSDOT-approved, Steel well monument (with a bolted lid) is then installed with a concrete seal to protect the monitoring well from tampering. Actual well installation data is depicted where appropriate on the boring logs. 82991/SEA7R080.doc Page e 4 of 23 July 11,2007 Copyright 2007 Kleinfelder KLEINFELDER 2.3 LABORATORY TESTING Laboratory tests were conducted on selected samples obtained from the explorations to characterize relevant engineering and index properties of the soils encountered in the borings. Laboratory tests on this project included determination of moisture contents and grain size distributions (sieves). The tests were conducted in general accordance with appropriate American Society of Testing and Materials (ASTM) standards; the standard testing procedures are summarized in the sections below and the test results are presented in Appendix B. Graphical results of certain laboratory tests are also depicted on the exploration logs in Appendix A. Visual soil classifications were conducted on all samples in the field and on selected samples in our laboratory. All soils were classified in general accordance with the United Soil Classification System, which includes color, relative moisture content, primary soil type (based on grain size), and any minor constituent soil tYp es. • Moisture content determination tests were performed on representative samples �.. to aid in identification and correlation of soil types. All determinations were made in general accordance with ASTM:D-2216. • Grain size analysis tests indicate the range of soil particle sizes included in a particular sample. Grain size analyses were performed on representative samples in general accordance with ASTM:D-422. 82991/SEAM080.doc Page 5 of 23 July 11,2007 Copyright 2007 Kleinfelder KLEINFELDER 3.0 SITE CONDITIONS 3.1 SURFACE CONDITIONS �r The project site is located within a single-family residential area located on a hillside just west of the City of Renton. Topography generally slopes downward to the north-northeast, toward an "unclassified" stream/creek which runs from the west to the • east along the northern margins of the project area. At the closest point (near MH No. 8 and 9), the adjacent stream channel is about 10 to 15 feet deep and is located about 10 to 20 feet away from the sewer line on the northeast side. The project area is developed as typical residential housing lots, with the western half to two-thirds of the alignment running across grass fields/lawn areas, and the eastern portion along existing gravel-surfaced access driveways. At both ends, portions of the alignment traverses paved streets. 3.2 SUBSURFACE CONDITIONS The subsurface conditions at the subject site, summarized in the sections below, were interpreted based on the explorations advanced along the proposed sewer alignment, our review of general geologic data, and our experience in similar geologic settings. The exploration logs in Appendix A provide a more detailed description of the soil/geologic strata and groundwater conditions encountered in our subsurface explorations. The Geologic Profiles (Figures 2 through 4) illustrate our stratigraphic interpretations along the proposed sewer alignment. 3.2.1 General Geologic Setting Based on general geologic and topographic information for the project area, surficial soil deposits in the area consist of glacial till, described as a compact and locally cemented, non-sorted mixture of clay, silt, sand, pebbles, cobbles and boulders. Exposed or near- surface bedrock is also mapped in the area, either as Eocene Volcanoclastic Deposits (Tukwila Formation) or Eocene Continental Sedimentary Deposits (Tiger Mountain Formation). 3.2.2 Soil Conditions In general, our explorations revealed the site to be underlain by loose to dense surficial soils, overlying weathered and unweathered bedrock. No glacial till deposits were encountered within our borings. The surficial soils, which generally consist of silty sand, occasionally interbedded with sand and silt lenses, are interpreted to be of either alluvial origin (upper portion) or weathered in-place, residual bedrock material (lower portion). 82991/SEA7R080.doc Page 6 of 23 July 11,2007 Copyright 2007 Kleinfelder a REM IMM KLEINFELDER Up to 18 inches of organic-rich surface soils or topsoil was found to be mantling these overburden soils. The thickness of the soil overlying the bedrock was found to vary significantly across the site. The greatest thickness (8 to 17 feet bgs) was observed along the eastern portion of the alignment (borings B-1 through B-3) and near the western end (boring B-6). The least thickness (3 to 5 feet bgs) was observed along the northwestern portion of the alignment (borings B-3B through B-5), where the top of the weathered bedrock appears to generally follow the existing ground surface. 3.2.3 Bedrock Conditions Our explorations revealed the overburden soils to be underlain by weathered and unweathered bedrock, interpreted to be of sandstone composition. For the purposes of this report, we have classified bedrock that could be penetrated with the 8-inch diameter, hollow-stem auger on the track-mounted drill rig as weathered, and bedrock that caused auger refusal as unweathered. The upper, weathered portion of the bedrock was drillable using the 8-inch diameter, hollow stem exploratory g auger drill rig. The thickness of the 9 weathered portion was found to vary significantly across the site; about 2 to 6 feet along the westernmost portion (borings B-413 through B-6), up to about 17 feet near MH No. 10 (boring B-4), and generally less than 3 feet along the eastern half of the sewer alignment (borings B-1 through B-3). Estimated field strengths range from very weak (R1) within the upper weathered zone to moderately strong rock (R3) within the underlying unweathered zone, which equate to strengths ranging from about 150 psi to 3500 psi (ISRM, 1981). Based on discussions with Mr. John Hobson, we understand that previous City of Renton sewer line excavations just to the north of the proposed project site revealed the weathered zone of the bedrock, which could be excavated with conventional earthwork equipment, to be on the order of 2 to 3 feet. It should be noted that the planned sewer pipe alignment appears to extend into the unweathered bedrock (below the auger refusal depth) at three distinct locations; in the vicinity of boring B-5 (at MH No. 11), near boring B-3B (about 90 feet east of MH No. 10), and in the vicinity of borings B-1 B (about 20 feet west of MH No. 7) and B-2 (about 40 feet east of MH No. 5). The location of weathered and unweathered bedrock plotted on the site plans is based on straight line interpolation between widely spaced explorations. The actual elevations and extent of bedrock encountered in the trench excavations may vary. Section 4.4 discusses bedrock excavation in further detail. 82991/SEA7R080.doc Page 7 of 23 July 11,2007 Copyright 2007 Kleinfelder s 0" KLEINFELDER 3.2.4 Groundwater Conditions • At the time of our May 2007 field explorations, the observed soil conditions and observation well readings indicated the presence of a relatively shallow groundwater system perched atop the bedrock surface. Samples collected from the upper, weathered zone of the bedrock were predominantly found to be in a non-saturated state (moist), which would indicate that the groundwater is perched atop the unweathered surface of the bedrock. However, it is possible that the groundwater partially penetrates into portions of the weathered bedrock through joints or fissure cracks. Groundwater levels observed in the explorations also generally follow the surface topography, sloping in a northeasterly direction, from a high elevation of about 240 feet near the west end of the alignment (in boring B-6) to a low elevation of about 215 feet near the east end of the alignment (in boring B-1). The thickness of the saturated zone within the overburden soils ranges from about 2 to 7 feet within the western portion of the alignment (west of boring 13-313, located just east of MH No. 10), and from about 5 to 15 feet within the central and eastern portions of the alignment. However, it should be noted that the thickness of the saturated soil zone within the planned sewer trench excavations may be less than this, depending upon the actual planned pipe invert elevations along the alignment. Within the western portion of the alignment, the saturated soil thickness appears to be limited to about 5 feet, or less. Along the central and eastern portions of the alignment, we would expect the thickness of the saturated soil zone within the planned trench excavation depths to range from 5 to 10 feet. The groundwater level in the monitoring well constructed in boring B-3 (at a topographic low point near the adjacent creek) was measured during construction to be about 2 feet above the ground surface. However, the surface and the upper few feet of soils at this location were observed to be in a moist (unsaturated) condition during drilling. This indicates that the groundwater at this location of the site may be under artesian pressure conditions, probably due to recharging groundwater from higher elevations on the hillside to the southwest. It should be noted that groundwater levels will likely fluctuate throughout the year in response to changing precipitation patterns, off-site construction activities, changes in site utilization, and other factors. Because our explorations were performed during an extended period of moderately wet weather, these observed groundwater conditions may closely represent the yearly average levels; higher levels probably occur during the 82991/SEA7RO80.d oc Page 8 of 23 July 11,2007 Copyright 2007 Kleinfelder MOWN KLEINFELDER winter and early spring months, while lower levels may occur during the drier summer and early fall months. 82991/SE47R080.doc Page 9 of 23 July 11,2007 Copyright 2007 Kleinfelder KLEINFELDER 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 GENERAL The results of our studies indicate the new sewer line will be constructed in variable deposits ranging from loose to medium dense silty sand (overburden material) to weathered and unweathered sandstone bedrock. Although the majority of the sewer pipeline will be constructed within the overburden soils or the upper, weathered portion of the bedrock, it should be noted that the planned sewer pipeline appears to extend into the unweathered bedrock (drilling refusal depth) at three distinct locations, as previously discussed. We anticipate that the sewer sections constructed within the overburden soils or the weathered zone of the bedrock can be installed by conventional trenching techniques utilizing trackhoe excavators and trench boxes for temporary shoring. Additional excavation measures, such as jack-hammering or hydraulic rams are expected to be required where the planned excavation depths extend into the unweathered bedrock surface, as discussed in more detail below. Based on the groundwater conditions observed in our explorations, we anticipate that the western half of the alignment (west of boring B-313, between MH No. 9 and 10) may .r be installed using conventional sump pump dewatering methods, provided that the thickness of the saturated soil zone within the trench excavation is less than about 3 feet. However, excavation of the eastern half of the alignment (east of boring B-313) will likely require the use of dewatering wells or closely spaced vacuum wellpoints, due .r. to the presence of 5 to 10 feet of saturated soils and the underlying bedrock. The selection of the most appropriate dewatering system will ultimately depend upon the actual subsurface conditions encountered during construction. Based on the preliminary sewer invert depths provided, we do not anticipate that significant amounts of over-excavation will be required, except to facilitate placement of pipe bedding over bedrock, and in limited areas to stabilize wet or soft subgrade. In general, we expect the soils excavated along the sewer alignment to be highly moisture sensitive due to their high fines content. Based on our experience with similar soil conditions, we recommend provisions for imported, select trench backfill be included in the contract documents. However, native soils may be suitable for use in 829911SEA7R080.doc Page 10 of 23 July 11,2007 Copydght 2007 Kleinfelder r KLEINFELDER some circumstances, based on an evaluation and approval in the field by the geotechnical engineer during construction. Conclusions and recommendations are presented in the following sections for temporary shoring for trench excavations, dewatering, bedrock excavation, pipe bedding, excavation backfill materials and compaction, pipe settlement, wet weather earthwork provisions, drainage and erosion control, pavement reconstruction, and rconstruction in vicinity of stream channel. 4.2 OPEN TRENCH PIPELINE CONSTRUCTION �- Excavation depths for the proposed sewer pipelines are anticipated to range from about 5 to 18 feet in depth. We anticipate that excavation into the loose to dense silty sand overburden soils and dense to very dense weathered sandstone along the majority of the project alignment can be accomplished using conventional trenching techniques and heavy excavating equipment, such as track-mounted excavators and trench boxes. However, ripping, jack-hammering, or use of hydraulic rams may be required within'the previously identified, isolated areas where the pipe invert elevations extend below the top of the unweathered bedrock surface (refusal encountered in borings). Use of narrow buckets equipped with ripping teeth may be required achieve acceptable production rates within the weathered bedrock underlying most of the site. Based on the groundwater conditions observed in our explorations, we anticipate that western half of the alignment (west of boring B-3B, between MH No. 9 and 10) may be installed using conventional sump pump dewatering methods, provided that the thickness of the saturated soil zone is less than about 3 feet above the bottom of the excavation. However, excavation of the eastern half of the alignment (east of boring B-313) will likely require the use of dewatering wells or closely spaced vacuum wellpoints so that excavations can be accomplished in relatively dry conditions and with minimal sloughing and caving. Dewatering is discussed in more detail in Section 4.3 (Dewatering Considerations). Construction should proceed as rapidly as feasible to limit the time temporary trench excavations are open. During wet weather, surface runoff water should be diverted away from the excavations, and collected at other suitable discharge points. Heavy construction equipment, building materials, and surcharge loads such as excavated soil should not be allowed within 1/2 the slope height from the top of any trench excavation. I 82991/SEA7R080.doc Page 11 of 23 July 11,2007 Copyright 2007 Kleinfelder KLEINFELDER Temporary excavations should be performed in accordance with current federal, state and/or local regulations. Temporary excavations in excess of 4 feet vertical height must be sloped or supported in accordance with Part N of Washington Administrative Code (WAC) 296-155. Although a standard trenchbox shoring system is typically used for pipeline construction, the sides of the trenchline excavations may alternatively be sloped. For planning purposes, recommend the following maximum cut slope inclinations, based on the soil layers encountered within our explorations and the , corresponding OSHA Soil Type classifications. Maximum Soil Type Inclination Loose Silty Sand (Type C Soils) 1Y2H:1V Medium dense to Dense Silty Sand (Type B Soils) 1 H:1 V Dense to Very Dense Weathered Sandstone (Type A Soils) 3/H:1V iate inclinations will ultimate) It should be noted that appropriate Y depend on the actual soil and groundwater seepage conditions exposed in the cuts at the time of construction. It is the sole responsibility of the contractor to ensure that the excavation is properly sloped or braced for worker protection. Furthermore, it should be noted that the cut slope inclination of any overlying soil layer should not be steeper than the underlying soil layer, according to OSHA guidelines. In addition to proper sloping, the excavation cuts should be draped with plastic sheeting for the duration of the excavation to minimize surface erosion and raveling. Excavations made below the water table will likely require dewatering and/or shoring. �. 4.3 DEWATERING CONSIDERATIONS Groundwater control measures will be required to construct the sewer interceptor in the dry. It should be the responsibility of the contractor to provide adequate dewatering measures for trench excavations to maintain sufficiently dry conditions during construction of the sewer pipeline. In general, we do not recommend using sump pumping to dewater a saturated zone.greater than 3 feet thick. For planning purposes and based on the groundwater conditions observed in our explorations, we anticipate that the western half of the sewer pipeline (west of boring B-313, located between MH No. 9 and 10) may be installed using conventional sump pump dewatering methods, provided that the thickness of the saturated soil zone is less than 3 feet. However, excavation of the eastern half of the sewer line (east of boring B-313) will likely require the use of dewatering wells or closely spaced vacuum wellpoints, due to the presence 829911SEA7R080.doc Page 12 of 23 July 11,2007 ' Copyright 2007 Kleinfelder KLEINFELDER of a saturated soil zone on the order of 5 to 10 feet. It should be noted that any dewatering system should be designed to draw down the groundwater to at least 1 foot below the bottom of the trench, in order to maintain stable subgrade conditions for the installation of the sewerline. For purposes of developing a dewatering plan, we estimate the permeability of the silty sand to be on the order of 5x10-3 to 5x10 ft/min, based on visual soil classification and the grain size laboratory tests. As such, the recommended dewatering approach should consist of closely spaced vacuum wellpoints, where a sump pump system is not feasible. Based on the range of hydraulic conductivity mentioned above and an average required drawdown of about 6 feet, the discharge rate from a 200-foot long ' wellpoint system is estimated to range from about 6 to 20 gpm. Greater flow rates may be encountered where the thickness of the saturated zone is greater. The area of the sewer alignment closest to the stream channel (near MH No. 9) may prove the most difficult to dewater, as the stream serves as the local discharge point for the shallow ' groundwater system and the groundwater in the area was found to be under significant, excess hydrostatic pressure head (artesian conditions). Kleinfelder is available to assist in the design of a dewatering plan. Alternatively, as a minimum, we recommend that Kleinfelder be allowed to review any dewatering plans and specifications developed by others, if included in the bid documents. �1 It should be noted that the exploration scope of work for the current study only included borings. In order to reduce the uncertainties associated with the prediction of groundwater conditions and requirements for construction dewatering, we recommend that additional exploratory test pits be excavated at selected locations along the proposed sewer pipeline. The groundwater levels and seepage rates are more readily evaluated in an open test pit than a small exploratory borehole. This would help better define the actual seepage rates to be expected during construction. 4.4 BEDROCK EXCAVATION CONSIDERATIONS ■ It has been demonstrated that sedimentary rocks, such as weathered sandstone, can typically be excavated by ripping because of the layered nature and generally lower strengths (Singh and Goel, 1999). At this site, the exploratory auger borings were able to penetrate to variable depths below the top of the weathered bedrock surface, indicating that excavation with heavy trackhoe and/or ripping would likely be feasible within the upper weathered zone of the sandstone, although ripping or pre-splitting may be required. Although blasting is sometimes used to facilitate excavations into bedrock, 82991/SEA7R080.doc Page 13 of 23 July 11,2007 Copyright 2007 Kleinfelder k'q KLEINFELDER we understand that this will not be an option on this project, given the difficulty of obtaining a blasting permit in a residential area and the stated project goal of limiting adverse impacts to the surrounding neighborhood. , Rockmass geomechanical characteristics such as Rock Mass Rating (RMR) and Rock Quality Designation (RQD) obtained from rock coring would better define rock conditions for excavation. The RMR collectively rates the rock mass based on strength, RQD, fracture spacing and quality and the presence of water. A rock mass with an RMR ' exceeding 60 typically will require blasting prior to excavation. Kleinfelder could provide a cost estimate for this additional work, if desired. Alternatively, exploratory test pits could be excavated at selected locations along the proposed sewer pipeline, in order to better evaluate the excavation characteristics of the bedrock (both weathered and ' unweathered zones). These test pits could be combined with the recommended additional test pits to evaluate groundwater seepage/dewatering characteristics. Getting a better handle on both of these subsurface conditions would provide more certainty regarding the construction requirements, which in turn would reduce the risk of unexpected construction cost overruns. 4.5 PIPELINE BEDDING AND SUPPORT The medium dense to dense overburden soils or weathered/unweathered bedrock .r encountered beneath the pipe invert elevations along the planned sewer alignment are expected to provide suitable support for the pipes, provided the trench excavation is properly dewatered and the subgrade soils are not disturbed during excavation and pipe installation. In some instances, loose or soft subgrade soils may extend below the pipe invert and will require over-excavation and replacement with a suitable foundation layer. Such over-excavation should be handled on a case-by-case basis, depending upon the local soil conditions encountered at the time of construction and as determined by the geotechnical engineer. However, based on soil conditions encountered in our explorations and the proposed sewer line invert elevations, it is our opinion that over- excavation will be minimal, provided that adequate dewatering is provided to maintain dry trench excavation conditions at all times during construction. If local sump pump .r methods are employed to dewater the trenchline, a working surface of 6 to 12 inches of clean crushed rock may be required below the subgrade level of the pipe trench, in order to provide stable subgrade conditions across wet portions of the trench bottom. We recommend that any peat or other soft, organic, or disturbed material encountered in the base of the excavations be removed and replaced with compacted crushed rock 82991/SEA7R080.doc Page 14 of 23 July 11,2007 Copyright 2007 Kleinfelder rl KLEINFELDER satisfying the specifications of Section 9-03.9(1) of the 2006 WSDOT Standard Specifications. This foundation layer should be compacted to a dense and unyielding condition. However, over-compaction should be avoided to prevent pumping of the base. Over-excavation for removal of unsuitable soils should extend to either side of the pipe a distance equal to the depth of over-excavation, or 3 pipe diameters, whichever is less. Over-excavation to remove unsuitable materials in the bottom of the trench should generally be limited to a depth of 3 feet. We recommend a Kleinfelder geotechnical engineer inspect the excavation base prior to bedding material placement to assess the subgrade suitability and the need for over-excavation. General pipe bedding recommendations for open trench pipeline construction are presented below. �- Pipe bedding material, placement, compaction, and shaping should be in a,. accordance with the pipe manufacturer's recommendations. Pipe bedding materials should be placed on relatively undisturbed native soils, or ' on compacted fill soils. If the native subgrade soils are disturbed, the disturbed material should be removed and replaced with compacted bedding material. Pipe bedding material should meet the gradation requirements for Bedding Material for Thermoplastic Pipe, Section 9-03.16 of the 2004 WSDOT Standard Specifications. Pipe bedding should be shaped to provide a firm, uniform cradle for the pipe. We recommend that a minimum 6-inch thickness of bedding material be provided beneath the pipe. The bedding material should also be placed and compacted around the pipe and extend to a height of not less than 6-inches above the pipe crown. In particular, we recommend that a minimum of 6 inches of pipe bedding be placed in areas where the trench bottom consists of bedrock to avoid stress concentrations on the pipe. Pipe bedding material and/or backfill around the pipe should be placed in layers and tamped with a suitable small compactor to obtain complete contact with the pipe. In areas where a trench box is used, the bedding material should be placed before the trench box is advanced. 4.6 EXCAVATION BACKFILL The soils encountered in the proposed trench excavations will likely consist of materials ranging from silty sand (overburden soils) and weathered sandstone bedrock material. Both of these materials exhibit a relatively high silt content and are generally expected 82991/SEA7R080.doc Page 15 of 23 July 11,2007 Copyright 2007 Kleinfelder KLEINFELDER to be highly moisture sensitive. We anticipate that these silty/sandy soils may only be reworked and recompacted given favorable weather conditions when they can be aerated to reduce their moisture content. Furthermore, these soils are expected to be ' difficult or impractical to dry out and properly compact during wet weather, due to their high silt content and in-place moisture condition. In general, soils used for pipeline , trench backfill should not contain any organic matter or debris, nor any individual particles greater than about 6 inches in diameter. ' Given the moisture sensitive nature of the native soils, we recommend that provisions for imported, select trench backfill be included in the contract documents, as a prudent ' measure. However, native soils may be suitable for use in some circumstances, based on an evaluation and approval in the field by the geotechnical engineer during construction. Imported fill should consist of clean sand and gravel (pit-run), satisfying the requirements of Section 9-03.14(1), Gravel Borrow, of the 2006 WSDOT Standard Specifications. ' Backfill material should be placed in 6 to 12-inch loose lifts and compacted using vibratory mechanical compaction equipment. Appropriate lift thicknesses depend on the material and the type of compaction equipment. If lightweight compacting equipment is used, lift thicknesses should be reduced. The initial lifts of the backfill material should not be dropped or bulldozed directly on the pipes. The use of heavy vibratory equipment should not be permitted directly over the pipe until a minimum of 2 feet of loose backfill have been placed and compacted above the pipe with lighter equipment. Fill soil compaction should be verified by means of in-place density tests performed during fill placement, so that adequacy of soil compaction efforts may be evaluated as earthwork progresses. i To provide adequate pavement subgrade support, we recommend that trench backfill placed within the upper 2 feet of the backfill zone in roadway areas should be compacted to at least 95 percent of its Modified Proctor maximum dry density (MDD), as determined in accordance with ASTM:D-1557. Within other areas, or more than 2 feet below roadway subgrade elevations, the trench backfill should be compacted to at least 90 percent the Modified Proctor MDD. In order to achieve these compaction ' requirements, the moisture content of backfill material should be within 2 to 3% of its optimum value. , 82991/SEA7R080.doc Page 16 of 23 July 11,2007 Copyright 2007 Kleinfelder kn KLEINFELDER In general, trench backfill compacted to 95 percent could settle about 1 to 2 percent of its thickness, wheras backfill compacted to 90 percent could settle slightly more. In our experience, less than 90 percent backfill compaction could lead to excessive settlement and is not recommended. It should be noted that many municipal standards for construction work within right-of-way areas requires 95 percent density, based on the Standard Proctor test (ASTM:D-698). This requirement is generally equivalent to about 90 percent compaction using the more stringent Modified Proctor criteria (ASTM:D-1557). 4.7 PIPE SETTLEMENT Construction of the proposed pipelines will result in little or no increase in soil bearing stress, and as a result, negligible post-construction pipe settlement is expected. However, disturbance of the bearing soils for the proposed pipelines during construction could result in future pipeline settlement. If the subgrade soils are disturbed during construction, the bottom of the trench should be over-excavated and replaced as described in Section 4.5 (Pipeline Bedding and Supporl). The recommendations for over-excavation and replacement of unsuitable materials below pipe invert levels are intended to minimize such settlements. 4.8 WET WEATHER EARTHWORK ' If earthwork is to be performed or fill is to be placed in wet weather or under wet subsurface conditions, when the control of soil moisture content is difficult, the following ' recommendations should be followed: Earthwork should be accomplished in small sections to minimize exposure to wet weather. Excavation or the removal of unsuitable soil should be followed promptly by the placement and compaction of a suitable thickness of clean granular fill. The size and type of construction equipment used may have to be limited to prevent soil disturbance; Granular fill material should consist of clean soil containing less than 5 percent fines (material passing the U.S. Standard No. 200 sieve), based on wet sieving the fraction passing the 3/-inch sieve. • The ground surface adjacent to the trenchline construction area should be graded to prevent surface water from ponding near and/or seeping into the trench excavations; i 82991/SEA7R080.doc Page 17 of 23 July 11,2007 Copyright 2007 Kleinfelder KLEINFELDER Excavation and placement of fill should be observed by the geotechnical ' consultant to verify that all unsuitable materials are removed and suitable compaction and site drainage is achieved. ' 4.9 DRAINAGE AND EROSION , The contractor should be responsible for the control of ground and surface water within the contract limits. In this regard sloping, slope protection, ditching, sumps, dewatering, and other measures should be employed as necessary to permit proper completion of , the work. We recommend that the contractor be required to submit a construction dewatering plan to the geotechnical engineer for approval prior to the start of , construction. Alternatively, Kleinfelder is available to assist in the design of a dewatering plan. , Most of the construction area is presently grass covered or unpaved, with surface slopes on the order of 5 to 12 percent. As such, the surficial soils within the project area ' are somewhat susceptible to erosion. In our opinion, erosion at the site during construction can be minimized by implementing the recommendations in the Wet Weather Earthwork section of this report, and can be controlled through the use of Best Management Practices. ' 4.10 PAVEMENT RECONSTRUCTION We anticipate that new pavement will be required over portions of the backfilled trenches near both ends of the planned sewer alignment. Although the borings advanced for this study were not located within the paved areas, we would anticipate that the existing pavement likely consists of 2 to 3 inches of Asphaltic Concrete Pavement (ACP) over variable thicknesses of crushed rock and gravel borrow base, based on typical pavement construction for similar roadways. The pavement within these areas appears to be in a relatively good condition, and is apparently adequate for the current traffic. The pavement subgrade should be compacted to at least 95 percent of its Modified , Proctor MDD (ASTM-D-1557), in accordance with the recommendations in the Backfill and Compaction section above. We recommend that any required replacement pavement section along the alignment match the existing ACP section, provided that no pavement distress or failure is apparent within the existing roadway. Generally, a minimum pavement section consisting of 3-inches of ACP over 6 inches of 5/8-inch minus crushed surfacing top course (CSTC) will provide adequate support for 82991/SEA7R080.doc Page 18 of 23 July 11,2007 Copyright 2007 Kleinfelder KLEINFELDER residential roadways (light traffic conditions). The CSTC should meet WSDOT specification 9-03.9(3) for Crushed Surfacing and be compacted to at least 95 percent of Modified Proctor maximum dry densities. 4.11 SEWER CONSTRUCTION IN VICINITY OF STREAM CHANNEL An "unclassified" stream/creek channel runs from the west to the east along the northern margins of the project area. At the closest point (near MH No. 8 and 9), the ' adjacent stream channel is about 10 to 15 feet deep and is located about 10 to 20 feet away from the sewer line on the northeast side. Topography generally slopes to the north-northeast, downward toward the stream/creek channel. To minimize the surface runoff and potential for siltation of the stream channel, we recommend that extra precaution be taken to limit surface erosion within the work area and the potential for off-site sedimentation. ' The sideslopes of the stream channel are on the order of 2H:1V. Given this slope inclination, and the subsurface soil and groundwater conditions observed within the site borings in this area, it is our opinion that the proposed construction of the sewer pipeline will not adversely impact the stability of the stream channel side slopes. ■ ■ 82991/SEA7R080.doc Page 19 of 23 July 11,2007 Copyright 2007 Kleinfelder " KLEINFELDER r 5.0 ADDITIONAL SERVICES ' 5.1 RECOMMENDED ADDITIONAL SERVICES r Because the future performance and integrity of the structural elements of the project will depend largely on proper site preparation, drainage, fill placement, and construction ' procedures, monitoring and testing by experienced geotechnical personnel should be considered an integral part of the construction process.
