Location: east of Garden Ave. N. and north of 8th St. Falk Annexation and Prezone (Erickson) LUA-02-019,ECF,A,R The applicant, Steve Beck, has requested Environmental Review for the proposed rezoning of this 5.96 acre annexation site (excluding streets) from King County's R-1 Zone to Renton's R-8 Zone. The current site is the northern section of the previously proposed original Falk Annexation of 13.66 acres. Because annexations are SEPA exempt(RCW 43.21 C.222) this environmental review is only for the rezone. Under Renton's R-8 zoning the + 6.43 acre site (including street right-of- way)could theoretically accommodate approximately 46 dwelling units, assuming 8 du/net acre. Because of steep slopes on a portion of the site the actual number of units allowed may be less than 46 units. The proposed rezone is consistent with Renton's Residential Single Family land use designation, as shown on the City's Comprehensive Plan Land Use Map. Location: The 6.43 acre site is located to the west of 102nd Avenue SE in King County and south of S 47th Street in Renton. The City of Renton abuts the subject site on its north and west.

RECOMMENDATION Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials make the following Environmental Determination: DETERMINATION OF DETERMINATION OF NON-SIGNIFICANCE NON-SIGNIFICANCE-MITIGATED. XX Issue DNS with 14 day Appeal Period. Issue DNS-M with 14 day Appeal Period. Issue DNS-M with 15 day Comment Period followed by a 14 day Appeal Period. C. MITIGATION MEASURES None Recommended. D. ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C.240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. 1. Earth Impacts: According to the Geotechnical report prepared by GeoEngineers, dated January 23, 2002, the soils consist of formation sandstone and glacial till deposits. The sandstone typically consists of very dense friable cemented sand. The glacial till typically consists of medium dense to very dense non-stratified deposits of silty sand with gravel and occasional cobbles and boulders. The Geotechnical report concludes that the proposed excavation and retaining wall construction is acceptable in this location. According to the project narrative, the project will not require exporting any soil. However, the project will require 130 cubic yards of imported soil. The imported fill will be utilized for slope restoration. On-site soil volumes moved during the activities would consist of the following: (1) initial slope cuts of approximately 650 cubic yards; (2) 70 cubic yards of drill cuttings generated during soldier pile installation; (3) approximately 390 cubic yards of the initial cut material will be placed behind the completed retaining wall; (4) approximately 200 cubic yards will be excavated to locate the upstream pipeline girth weld including excavation near the potential pipeline defect area, then filled; (5) approximately 330 cubic yards of remaining initial cut soils plus drill cutting will be used to regrade the slope above the retaining wall in addition to the 130 cubic yards of imported soil. Some hillside vegetation (i.e. blackberry bushes, cherry trees, etc.) would be removed as part of the excavation and wall construction. No other structures are proposed within the project area. Staff expects minor erosion to occur as a result of this project; however, the applicants construction mitigation plan along with code requirements should alleviate any impacts to the surrounding area. Therefore, no additional mitigation measures are necessary. Mitigation Measures: No further mitigation is recommended. Nexus: N/A 2. Air Impacts: During project excavation, dust and equipment emission odors will potentially be emitted. If site conditions are dry and dust becomes problematic, water will be applied to the site to keep dust to a minimum. Air quality will be monitored by the Olympic Pipeline Company during excavation. Mitigation Measures: No further mitigation is recommended. Nexus: N/A 3. Water and Stormwater Impacts: The site does not have any storm water facilities located directly adjacent to the construction area. Therefore, the applicant is proposing to direct any stormwater runoff from the project site through straw bales toward Benson Road (approximately 400 feet to the west). Once the stormwater runoff reached Benson Road South, the ercrpt.doc City of Renton P/B/PW Department L Envii vital Review Committee Staff Report OLYMPIC PIPELINE RETAINING WALL ----"' LUA-02-135,ECF REPORT AND DECISION OF JANUARY 14,2003 Page 3 of 3 water would be collected into a catch basin and directed into the Benson Road South stormwater system. In addition, the applicant's Construction Mitigation Plan will assist in mitigating any other potential impacts to ground, surface and stormwater. Mitigation Measures: No further mitigation is recommended. Nexus: N/A E. COMMENTS OF REVIEWING DEPARTMENTS The proposal has been circulated to City Departmental/Divisional Reviewers for their review. Where applicable, these comments have been incorporated into the text of this report as Mitigation Measures and/or Notes to Applicant. X Copies of all Review Comments are contained in the Official File. Copies of all Review Comments are attached to this report. Environmental Determination Appeal Process: Appeals of the environmental determination must be filed in writing on or before 5:00 PM on February 3, 2003. Appeals must be filed in writing together with the required $75.00 application fee with: Hearing Examiner, City of Renton, 1055 South Grady Way, Renton, WA 98055. Appeals to the Examiner are governed by City of Renton Municipal Code Section 4-8-110. Additional information regarding the appeal process may be obtained from the Renton City Clerk's Office, (425)-430-6510. Advisory Notes to Applicant: The following notes are supplemental information provided in conjunction with the environmental determination. Because these notes are provided as information only, they are not subject to the appeal process for environmental determinations Planning: 1. RMC section 4-4-030.C.2 limits haul hours between 8:30 am to 3:30 pm, Monday through Friday unless otherwise approved by the Development Services Division. 2. Commercial, multi-family, new single family and other nonresidential construction activities shall be restricted to the hours between seven o'clock (7:00) a.m. and eight o'clock (8:00) p.m., Monday through Friday. Work on Saturdays shall be restricted to the hours between nine o'clock (9:00) a.m. and eight o'clock (8:00) p.m. No work shall be permitted on Sundays. 3. Within thirty (30) days of completion of grading work, the applicant shall hydroseed or plant an appropriate ground cover over any portion of the site that is graded or cleared of vegetation and where no further construction work will occur within ninety (90) days. Alternative measures such as mulch, sodding, or plastic covering as specified in the current King County Surface Water Management Design Manual as adopted by the City of Renton may be proposed between the dates of November 1st and March 31 st of each year. The Development Services Division's approval of this work is required prior to final inspection and approval of the permit. Plan Review: 1. Retaining walls greater than 4 feet in height will need to be reviewed under separate Building permits. A licensed engineer with geo-technical expertise must be retained for proposed walls or rockeries greater than four feet in height. The engineer must monitor construction, and verify in writing that construction was done in general accordance with ARC standards and with his/her supplemental recommendations, in a professional manner and of competent and suitable material. Written verification by the engineer must be provided to the City of Renton public works inspector prior to approval of an occupancy permit. Locations of water and sewer mains will be considered in relation to the retaining walls. It may require special protection or relocation of the lines under or near the retaining wall construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. If construction occurs during the months of October 1 through April 30, wet season, additional erosion control requirements apply as follows. The following provisions for wet season construction are also detailed in Appendix D of the 1998 King County Surface Water Manual. Please ensure your site is protected and complies with the special provisions outlined below.The basic requirements are: • The allowed time that a disturbed area can remain unworked without cover measures is reduced to two (2) days, rather than seven (7) days. Stockpiles, steep cut, and fill slopes are to be covered or protected with mulch, sod, plastic covering, jute mat etc. if left unworked for more than 12 hours. Cover materials (plastic, matting, etc.) sufficient to cover all disturbed areas, shall be stockpiled and available on site. ercrpt.doc City of Renton P/B/PW Department Envir 'ntal Review Committee Staff Report OLYMPIC PIPELINE RETAINING WALL LUA-02-135,ECF REPORT AND DECISION OF JANUARY 14,2003 Page 4 of 3 4. All areas that are to be unworked during the wet season shall be seeded within one week of the beginning of the wet season. 5. Mulch is required to protect all seeded areas. 6. Fifty linear feet of silt fence (and the necessary stakes) per disturbed acre must be stockpiled on site. 7. Properly installed silt fencing is mandatory along the downslope of all disturbed areas of the site. Perimeter protection filters runoff and reduces the amount of sediment that may leave the site. 8. Sediment retention is required unless no offsite discharge is anticipated for the specified design flow. 9. Construction road and parking lot stabilization are required for all sites unless the site is underlain by coarse- grained soil. 10. Surface water controls are required unless no offsite discharge is anticipated for the specified design flow. 11. Phasing and more conservative BMPs must be evaluated for construction activity near surface waters. 12. Any runoff generated by dewatering shall be treated through construction of a sediment trap when there is sufficient space or by releasing the water to a well vegetated, gently sloping area. Since pumps are used for dewatering, it may be possible to pump the sediment-laden water well away from the surface water so that vegetation can be more effectively utilized for treatment. A straw bale filter shall be placed around the discharge from the dewatering pump. If there is not space for a sediment trap or 25 feet of suitable vegetation, other filtration methods shall be required. 13. The frequency of maintenance review should be increased from weekly to daily where warranted. Fire Prevention: 1. The applicant is required to notify the City of Renton's Fire Department prior to any excavation or pipeline repair activities. 2. The applicant is required to notify the City of Renton's Fire Department immediately if there is a release from the pipeline during the excavation and/or repair activities. 3. Secondary access to the Country Hills Apartments must be maintained at all times. Building: 1. Work to proceed according to 1997 UBC, geotechnical recommendations and structural engineer's report. Special Inspections are required. ercrpt.doc MP111.4 OLYMPIC PIPE LINE CO. 20—INCH PIPELINE NORTHWEST QUARTER OF SECTION 20, T23 N, R5 E, W.M.

Signature of Director or Authorized Representative Date routing.doc Rev.10/93 CITY OF RENTON ECONOMIC DEVELOPMENT NEIGHBORHOODS, AND STRATEGIC PLANNING MEMORANDUM DATE: January 2, 2003 TO: Jason Jordan- (IFROM: Rebecca Lind STAFF CONTACT: Don Erickson SUBJECT: Olympic Pipeline Retaining Wall, 1600 S.Eagle Ridge Drive; LUA-02-135,ECF The Olympic Pipe Line Company is proposing construction of a variable height rock shoring/retaining wall to facilitate the inspection of a 20" pipeline near Benson Road South. The wall construction and inspection process for the pipe line are estimated to take four or five weeks. The applicants are proposing to mitigate potential impacts with temporary erosion and sedimentation control measures. The site is located approximately 125' east of Benson Road South within the City of Seattle Transmission Line right-of-way easement. The site has a split land use designation with the southern portion designated Neighborhood Center (CN) and the northern portion designated Residential Multi-family — Infill (RM-I). The zoning for these two designations is CN and RM-I. The site is located in an area mapped for erosion, steep slopes and landslide hazards on Renton's Sensitive Area Maps. The subject site is one to three sites in Renton that have been identified that require excavation, examination, and possible repair. Two of the three sites have been completed, but the third, because of its steep topography has not yet been excavated. Construction of the proposed retaining wall will allow construction and inspection equipment onto the site. The disturbed area of work will be approximately 12,400 square feet. The applicants note that a private alternate approach road used by Country Hills Apartments and other residences will be closed to through traffic for nearly two weeks during the construction activity. Relevant Comprehensive Plan Policies: Policy U-3. Process permits and approvals for utilities and facilities in a fair and timely manner and in accord with development regulations that encourage predictability. Policy U-4. Strive to protect the health and safety of Renton citizens from recognized harmful effects of utility generated environmental hazards. Policy U-5. Encourage the appropriate siting, construction, operation, and decommissioning of all utility systems in a manner that reasonable minimizes impacts on adjacent land uses. Olympic Pipe Line Company...Laining Wall and Inspection/Repair 2 01/02/03 Objective U-C: Ensure non-City managed utilities provide service commensurate with required State mandated public service obligations and established safety and welfare standards. Policy U-31. Coordinate periodic updating of the utility element and relevant implementing development regulations with adjacent jurisdictions and purveyors. Analysis: The proposed construction to allow the inspection of this regional facility is clearly in the public interest and supported by Objective U-C. It is unclear why landscaping (4-inch diameter flowering cherry trees), that presumably were required at the time the Country Hills Apartments were constructed, is not being replaced. A landscape plan should, in staff's opinion, be provided as a part of this application. Policy U-5 would support efforts to minimize impacts, including aesthetic impacts, on adjacent land uses. Recommendation: Support this application as being in the public interest while encouraging the applicant to consider replacing the existing landscaping with the same or appropriate alternatives. cc: Don Erickson Document2\d City of Renron Department of Planning/Building/Public Wurec� ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET REVIEWING DEPARTMENT: ?Ian LIR ex.() COMMENTS DUE: JANUARY 3, 2003 APPLICATION NO: LUA-02-135,ECF DATE CIRCULATED: DECEMBER 16,2002 CITY OF RENTON EICEiVED APPLICANT: Kurt Hayashida PROJECT MANAGER: Jason Jordan PROJECT TITLE: Retaining Wall for Olympic Pipeline WORK ORDER NO: 77065 DEC ' 9 2002 n' LOCATION: 1600 S.

Signature of Director or Authorized Representative Date routing.doc Rev.10/93 CITY OF RENTON MEMORANDUM Date: December 23, 2002 To: Jason Jordan From: Mike Dotson Subject: Retaining Wall for Olympic Pipeline; LUA-02-135, ECF I have reviewed the subject Environmental and Development application. The following are my comments related to the environmental impacts, policy, and code-related comments: Existing Conditions: WATER There is a 10-inch water main to the north (not within the construction zone) of the project location. Fire flow available at the site is approximately 3,200 gpm. Static Water pressure is between 51-77 psi. Pressure Zone is 196. The site is outside the Aquifer Protection Zone. SEWER There is a 8" sewer main in the project vicinity. STORM There are no know existing constructed storm water facilities near the project location. STREETS No frontage improvements exist along the frontage of this site. Code Related Comments: No code related comments. Recommended Conditions: 1. Retaining walls greater than 4 feet in height will need to be reviewed under separate Building permits. A licensed engineer with geo-technical expertise must be retained for proposed walls or rockeries greater than four feet in height. The engineer must monitor construction, and verify in writing that construction was done in general accordance with ARC standards and with his/her supplemental recommendations, in a professional manner and of competent and suitable material. Written verification by the engineer must be provided to the City of Renton public works inspector prior to approval of an occupancy permit. Locations of water and sewer mains will be considered in relation to the retaining walls. It may require special protection or relocation of the lines under or near the retaining wall construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County H:\Division.s\Develop.ser\Dev&plan.ing\PROJECTS\02-135.jason\plan review comments.doc Surface Water Design M 11. This will be required during the cu.,-....ruction of both off-site and on-site improvements as well as building construction. • 3. If construction occurs during the months of October 1 through April 30, wet season, additional erosion control requirements apply as follows; The following provisions for wet season construction are also detailed in Appendix D of the 1998 King County Surface Water Manual. Please ensure your site is protected and complies with the special provisions outlined below. The basic requirements are: 1. The allowed time that a disturbed area can remain unworked without cover measures is reduced to two (2) days, rather than seven (7) days. 2. Stockpiles, steep cut, and fill slopes are to be covered or protected with mulch, sod, plastic covering,jute mat etc. if left unworked for more than 12 hours. 3. Cover materials (plastic, matting, etc.) sufficient to cover all disturbed areas, shall be stockpiled and available on site. 4. All areas that are to be unworked during the wet season shall be seeded within one week of the beginning of the wet season. 5. Mulch is required to protect all seeded areas. 6. Fifty linear feet of silt fence (and the necessary stakes) per disturbed acre must be stockpiled on site. 7. Properly installed silt fencing is mandatory along the downslope of all disturbed areas of the site. Perimeter protection filters runoff and reduces the amount of sediment that may leave the site. 8. Sediment retention is required unless no offsite discharge is anticipated for the specified design flow. 9. Construction road and parking lot stabilization are required for all sites unless the site is underlain by coarse-grained soil. 10. Surface water controls are required unless no offsite discharge is anticipated for the specified design flow. 11. Phasing and more conservative BMPs must be evaluated for construction activity near surface waters. 12. Any runoff generated by dewatering shall be treated through construction of a sediment trap when there is sufficient space or by releasing the water to a well vegetated, gently sloping area. Since pumps are used for dewatering, it may be possible to pump the sediment-laden water well away from the surface water so that vegetation can be more effectively utilized for treatment. A straw bale filter shall be placed around the discharge from the dewatering pump. If there is not space for a sediment trap or 25 feet of suitable vegetation, other filtration methods shall be required. 13. The frequency of maintenance review should be increased from weekly to daily where warranted.

Chapman, Hazardous Materia s 1Pecialist SUBJECT: Fire Department Comments—Retaining Wall for Olympic Pipeline The following are comments from the Fire Department concerning the planned retaining wall work for Olympic Pipeline. There are three main concerns from the Fire Department: 1.) Closure of the secondary access road for Country Hills Apartments, 2.) Notification to the Fire Department before conducting any excavation or pipeline repair activities, and 3.) Notification to the Fire Department immediately if there is a release from the pipeline during the excavation and/or repair activities. The proposed work plan indicates that the alternate access road to Country Hill Apartments is to be closed to traffic for the duration of the project. This is the only secondary access to the apartments, and at least a portion of this road must remain open to allow emergency vehicles access in case of an emergency. The contractor shall provide a plan to allow continued access throughout the duration of the project. A work schedule shall be submitted to the Fire Department, and designated personnel shall be notified verbally before any work is conducted near the pipeline. This includes the initial excavation work and any subsequent repairs that must be made to the pipeline. In the event of a break in the pipeline, the Fire Department must be notified immediately.

Retaining Wall installation near Benson Drive. Attached are copies of the Letter of Consent from Seattle City Light, and the signature page of the permit application signed by Robert Hancheroff. Kurt mentioned that you were concerned about access to the residences on the private road. Sheet SH5.0 shows traffic controls for the private road. Our intent is to maintain access from Benson Road to the driveway just beyond the asphalt berm, and work with the resident on timing of blockages should the drill rig operation require short periods where the driveway is blocked. The signage at the west end of the project is shown as "Road Closed to Through Traffic", but is not blocked off. The road will be closed off at the east end near the driveway to the apartments to keep apartment traffic from driving through the construction zone. The apartments and the driveway adjacent to the apartment entrance will be accessable by way of Eagle Ridge Drive. Please let Kurt or me know if there are any other outstanding issues. Thanks.

PURPOSE OF CHECKLIST: The State Environmental Policy Act (SEPA), Chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you .to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or"does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal �ov\G "proposer," and "affected geographic area," respectively. ,�QpN • �N C�c✓ n O�°I‘C Environmental Checklist R; A.

The proposed retaining wall and subsequent pipeline inspection dig of the OPLC 20-inch petroleum pipeline is scheduled for Spring 2003, or as soon as permits and weather conditions allow. We anticipate that the work can be completed in approximately four to five weeks after starting. The hours of work will not extend beyond 7:00 a.m. to 8:00 p.m. on Monday through Friday. The proposed hauling route for retaining wall materials and imported quarry spall rocks (approximately five truck and trailers of rock)is shown on the attached Thomas Guide maps. Except for hauling the retaining wall piles, timbers and the quarry spall rocks, there will be little traffic to and from the site, except at the beginning and end of the workdays. The alternate access road to the Country Hills Apartments will be closed to through traffic during the retaining wall installation. Signs indicating road closure will be located as shown on Sheet SH5.0. ' The work hours will conform to the City of Renton Noise Ordinance requirements. Temporary erosion and sedimentation control measures, as shown and described on Sheet SH5.0, will be implemented to mitigate erosion and runoff during the project. A street sweeper will be used, as necessary, to prevent mud from being tracked from the work areas to Benson Road South.

November 18, 2002. �� $,P1 S 1 INTRODUCTION The Olympic Pipe Line Company (OPLC) operates 16-inch and 20-inch petroleum pipeline systems within Renton, Washington. These lines have been examined internally utilizing a geometry inspection tool for deformation indications and a magnetic flux tool for metal loss indications. OPLC needs to excavate and visually inspect sections of each pipeline where the internal inspection data indicate a possible defect so that any defects meeting established repair criteria can be repaired. Inspection and repairs of the 16-inch line were completed in 2001. Examination of internal test data for the 20-inch pipeline identified three sites in Renton requiring excavation, examination and possible repair. Site numbers 340 and 350 have been completed. Because of steep topography in the immediate vicinity of Site 360, this site has not yet been excavated. Installation of a retaining wall will be necessary for equipment access to the dig site. This narrative addresses the work to be completed in order to excavate, inspect and repair, if necessary, Site 360 at OPLC Milepost 111.4, located near Benson Road South. The project site vicinity map is provided in attached Sheet SH1.0. The project site is shown in attached SH2.0 and sheet pile shoring wall details are shown in attached SH3.0 and SH4.0. Temporary erosion and sedimentation controls (TESC),with relevant site characteristics are shown in attached SH5.0. A neighborhood detail map is provided as SH6.0. The purpose of this document is to describe the work for which City of Renton permits are being sought and the methods to be used to protect critical areas and other important features. After a description of the work activities, general environmental controls to be employed, and anticipated project schedule, site conditions and special resource protection measures at the site are presented. PROJECT DESCRIPTION . SITE INFORMATION The project work("site")is located on three separate properties: (1) King County Parcel 2023059010, owned by Puget Sound Energy(PSE); (2)King County Parcel 2023059086, owned by Topman Fellow Corporation; and (3) King County Parcel 2023059097, owned by Robert W. Hancheroff. The retaining wall will be constructed on the PSE property; regrading and temporary stockpiling and staging will occur on the other two parcels. The PSE property has no address,but is located to the east of Benson Road South on a private alternate approach used by the Country Hills Apartments. The other two property addresses are 1600 and 1611 Eagle Ridge Drive South. The disturbed area of work will be approximately 12,400 square feet, as shown in SH5.0. The zoning designation of the site and surrounding properties is RM-I or CN. The PSE site currently is used to convey utilities owned by Olympic Pipe Line and Seattle City Light. The portion of the Topman property that will be impacted is undeveloped; the remainder is multi-unit residential. The Hancheroff property is occupied by an office building; 1 the portion of the property that will be impacted is undeveloped, however a paved parking lot will be used for access. The site is located in mapped erosion, steep slope and landslide hazard areas on City of Renton Sensitive Area Maps. Based on observations during a geotechnical evaluation conducted at the site by GeoEngineers in November 2001, soil at the site consists of 3 to 6 feet of fill (loose to medium dense silty sand with variable gravel) overlying 9 to 17 feet of glacial till (very dense silty sand with occasional gravel) overlying bedrock(friable sandstone). Groundwater was not observed in the borings, completed to depths ranging from approximately 24.5 to 35 feet below ground surface; however,zones of perched groundwater may intermittently occur within the glacial till. The proposed use of the properties will not change as a result of the proposed project. However, an approximately 175-foot soldier pile wall with timber lagging will remain adjacent to the private drive on the PSE property at the conclusion of activities. Further, the northern portions of the other two properties in the work area will be regraded from the existing slope. Final slope grades will not be steeper than current grades. No off-site improvements are proposed as a result of the project. Access to the work site will be from the private alternate approach to the Country Hills Apartments, along the pipeline easement from the parking lot of the Eagle Ridge Professional Center at 1600 Eagle Ridge Drive South, and from the paved parking lot of The Lodge at Eagle Ridge at 1611 Eagle Ridge Drive South. The total estimate construction cost of the project is $225,000. As a result of the project, there will be no export of soil. The only imported fill will consist of approximately 130 cubic yards of quarry spalls placed on the slope during slope restoration. The purpose of the quarry spall blanket is to improve drainage on the slope. On-site soil volumes moved during the activities will consist of the following: (1) initial slope cut of approximately 650 cubic yards, (2) 70 cubic yards of drill cuttings generated during soldier pile installation, (3) approximately 390 cubic yards of the initial cut material will be placed behind the completed retaining wall, (4) approximately 200 cubic yards will be excavated to locate the upstream pipeline girth weld and to excavate at the potential pipeline defect, then filled, and (5) • approximately 330 cubic yards of remaining initial cut soil plus drill cuttings will be used to • regrade the slope above the retaining wall. Several cherry trees, each approximately 4-inch-diameter at chest height (shown in SH5.0),will be removed to construct the retaining wall. These trees will not be replaced. No structure of any kind, except the retaining wall,will be constructed for the project. SHEET PILE RETAINING WALL INSTALLATION • As discussed above, a soldier pile retaining wall will be installed at the site to allow construction equipment access. The wall will be installed downslope of the proposed inspection dig. The slope behind the wall will be filled with material excavated from the slope above the pipeline. A quarry spall blanket will be placed on the slope above the wall for future drainage, 2 -7 and the slope will be regraded, as shown in SH4.0. The resulting new site grade over the pipeline will allow for safe equipment access and excavation of the inspection dig. GeoEngineers provided recommendations for the retaining wall in their "Report, Geotechnical Engineering Services, Proposed Retaining Wall" for OPLC dated January 23, 2002 (attached) and the details are provided in Sheets SH3.0 and SH4.0. The retaining wall installation is expected to be completed in approximately two weeks. During wall installation, the private access road to the Country Hills Apartments and other residences,which is an alternate access,will be closed to through traffic. INSPECTION DIG To inspect the pipeline anomaly, a pothole will be excavated to locate the upstream girth weld. Once the weld is located,the potential defect location can be measured from the weld and excavated. The pipeline will usually require,at most, a fiberglass wrap ("clockspring")repair. If a cutout and weld of the pipe is necessary, the clockspring repair would be temporary and the cutout would be scheduled for a later time. After inspection and repair, the coating on the pipe will be repaired, the excavation backfilled, and site restored (see following section). The inspection dig and site repair is expected to be completed in two weeks. The trench for inspection of the pipeline will be approximately 6-to 22-feet wide, 8-feet deep, and from 20- to 36-feet long. Total soil volume generated at the inspection dig site and pothole at the girth weld will be approximately 200 cubic yards. The excavated soil will be temporarily stockpiled on one side or end of the trench and protected from erosion prior to its subsequent use as backfill. SITE RESTORATION After completion of inspection and/or temporary repair, the upper portion of the slope will be regraded to an approximate 3:1 slope to incorporate the soil remaining from the original cut (as shown in Sheet SH4.0). There will be no export of material from the site. The site will be seeded with an erosion control grass species and covered with straw, or hydroseeded to minimize erosion and facilitate revegetation. In the event that a cutout and weld is required to repair the pipe, excavated soil and the slope will be temporarily seeded with grass until equipment can be remobilized to the site for repair during a scheduled pipeline shutdown. Final site repair will be completed as described above. TEMPORARY EROSION AND SEDIMENTATION CONTROLS Temporary erosion and sedimentation control measures that meet or exceed the minimum requirements of City of Renton Municipal Code (Chapter 4-4-060) will be implemented prior to grading or excavation. The following Best Management Practices (BMPs) apply to the site: 1. The boundaries of the temporary work and access areas will be clearly marked in the field (using orange plastic fencing) prior to construction. During construction, no disturbance 3 • beyond the marked limits will be permitted. 2. Filter fences will be installed prior to construction to help confine sediment transport and runoff to the immediate work area, as shown in Sheet SH5.0. In the unlikely event that excavated soils are very wet, a filter/straw containment area for the soil stockpile will be prepared. Silt fencing will be installed as follows: • The filter fabric will be Mirafi 700X or equivalent and will be purchased in a continuous roll cut to length of the barrier to avoid use of joints where practical. When joints are necessary, filter fabric will be spliced together only at a support post with a minimum 6" overlap, and both ends of the splice will be securely fastened to the post. • T-bar fence posts will be spaced between 4 feet to a maximum of 6 feet apart and driven securely into the ground a minimum of 18 inches. • A shallow swale will be excavated,roughly 6 inches wide and 6 inches deep,upslope and adjacent to the posts to allow the filter fabric to be buried. • The filter fabric will be wired to the fence,and at least 20 feet of the fabric will be laid into the shallow swale. The filter fabric will not extend more than 36 inches above the original ground surface and will not be nailed or stapled to any trees. • The shallow swale will be backfilled with native soil. • Upon removal of the silt fencing,the disturbed areas will be immediately seeded and permanently stabilized. Silt fencing will be disposed of in a proper manner. • Silt fences will be inspected immediately after each rainfall and at least daily. Any required repairs will be made immediately. 3. Site preparation, excavations, and fill placement will be completed during drier weather to the extent practical. Precipitation and runoff patterns will be monitored during construction. If inclement weather occurs, stockpiles of excavated materials will be covered with plastic or another protective covering. 4. Denuded areas will be covered with straw mulch as appropriate to reduce sediment runoff impacts. 5. Where surface water is present, it will be routed to the base of the slope to the access road, and down the hill through check structures of straw bales (see Sheet SH5.0). Ultimate discharge of the surface water will be the catch basin at the intersection of the access road with Benson Road South. 6. Daily inspections of the erosion control measures will be conducted throughout the construction period to ensure the effectiveness of the measures and to determine the need for maintenance,repairs or additional measures. 7. Once final grading is complete, soils in graded or disturbed areas will be tracked in place so that the track grouser marks provided a texture to help resist erosion. 8. Straw mulch or other erosion control materials such as jute matting or hydroseed with binder will be used as appropriate on disturbed areas following construction. 9. A seed mix appropriate for the area will be used to revegetate all disturbed surfaces to provide erosion protection after construction is complete, unless otherwise dictated by property owner. 10. Until the permanent erosion protection vegetation is established and the site is stabilized, periodic monitoring will be performed to evaluate the effectiveness of post construction 4 erosion control measures and repair and/or modify them as appropriate. Areas of observed significant erosion will be repaired using an appropriate combination of the methods discussed above. BMPS FOR PREVENTING AND CONTAINING PETROLEUM SPILLS To prevent petroleum products or other material from contaminating soils and water bodies during vehicle and equipment maintenance, the following BMPs will be implemented: 1. Construction equipment and vehicles will be properly maintained to prevent leaking of petroleum products. 2. Specific staging areas for equipment and vehicle maintenance will be established away from wetlands,water bodies and drainage pathways. 3. Drip pans and tarps or other containment systems will be used when fueling, changing oil and working with other vehicle and equipment liquids. 4. Any petroleum contaminated soils or material will be disposed of off site at an approved disposal facility after proper testing and manifesting takes place. 5. Vehicle and equipment fueling will be attended at all times by site personnel. 6. Spill cleanup materials will be stored on site and employees will be trained in spill control procedures. SCHEDULE OPLC anticipates performing this work in the spring of 2003, or as soon thereafter as the necessary permits and approvals can be obtained. In general, work is anticipated to begin within one month of permit issuance, or when weather conditions allow. The retaining wall installation is expected to be completed in two weeks, and grading/site restoration in an additional two weeks. CONTRACTOR OPLC intends to bid the work to three general contractors that specialize in, and are trained to perform pipeline construction work. The three contractors are PLEM CO, Snelson Companies Inc. and Mountain Pacific Pipeline Inc. Copies of their State Contractors Registration certificates are included with the City of Renton Building Permit Application. The successful contractor will provide proof of obtaining a City of Renton Business License prior to receipt of the building permit.

The site is shown relative to surrounding physical features on the Vicinity Map, Figure 1 and the Site Plan, Figure 2. PROJECT DESCRIPTION Our understanding of the project is based on meetings and telephone conversations with OPLC personnel, several site reconnaissance, pipe line alignment and depth data provided by OPLC, and a site topographic survey completed by Reid Middleton. We understand that an anomaly in the pipe line was discovered at the site during a periodic evaluation of the pipe line using a smart pig device. In order to further evaluate the nature of the anomaly at this location, the soil above the pipe line needs to be excavated. Due to the topography in the immediate vicinity of the anomaly, construction equipment can not gain access to the pipe line to excavate the soil from above the pipe line. The pipe line alignment runs j l parallel to and near the crest of a steep cut slope in the immediate vicinity of the anomaly. In order to provide access for construction equipment, a retaining wall constructed down slope of the pipe line has been proposed. — SITE DESCRIPTION The site is located within the Puget Sound Energy (PSE) power transmission line alignment due east of Benson Road in Renton, Washington. The OPLC alignment is also located in the PSE easement in the site vicinity. An access road servicing single family residences and a large L.J apartment complex is located north of and parallel to the pipe line alignment. Steep cut slopes likely associated with the construction of this access road are located between the pipe line ti alignment and the access road. The height of the cut slope ranges from about 15 to 20 feet high in the project vicinity. { The proposed retaining wall would be located between the access road and the pipe line alignment, most likely near the toe of the existing cut slope. We understand based on our discussions with OPLC that the length of pipe that needs to be exposed in this area is on the order of 100 feet. We also understand that the contractor must have at least 10 feet of level working au G e o E n g i n e e r s 1 File No. 0894-132-00\012302 `I " area on either side of the pipe. The contractor intends to use an excavator weighing less than 50 kips. The pipe line must have at least 36 inches of soil cover following completion of the work. DESIGN PHASE SCOPE OF SERVICES d The purpose of our services is to evaluate surface and subsurface conditions as the basis for developing geotechnical recommendations for design and construction of the proposed retaining structure. Our specific scope of services includes the following tasks: 1. Review available geotechnical information, including geologic and topographic maps and other in-house information and reports. 2. Coordinate the field activities with PSE and adjacent property owners and obtain utility clearances. 3. Explore subsurface soil and ground water conditions at the site by drilling four borings to depths ranging from 241 to 36 feet below the existing ground surface. 4. Complete a topographic survey of the site showing existing improvements, property {f boundaries, and easements. 5. Conduct laboratory testing consisting of moisture content determinations and grain size distribution analyses. l6. Perform engineering analyses and evaluate data derived from the subsurface investigation and laboratory testing program with respect to the items listed in Task 7 below. 7. ' Prepare a report summarizing the results of our geotechnical engineering services including descriptions of surface and subsurface conditions, a siteplan showingboringlocations and P other pertinent features, summary boring logs, and laboratory test results. Geotechnical f Y engineering conclusions and recommendations pertaining to the following items are lY presented: • a) Earthwork including site preparation, suitability of on-site soils for re-use as fill, fill placement and compaction, wet weather earthwork, and erosion control; b) Temporary and permanent cut and fill slopes; c) -Temporary and permanent drainage considerations; J d) Seismic coefficients and criteria consistent with the 1997 UBC code requirements; e) Soldier pile wall design recommendations including earth pressure diagram and construction considerations L 8. Provide project management for the geotechnical tasks. FIELD EXPLORATIONS AND LABORATORY TESTING FIELD EXPLORATIONS The subsurface conditions at the site were evaluated by drilling four borings to depths it ranging from 24'/2 to 35 feet. The borings have been designated borings B-1 through B-4. The • locations of the four borings are shown in Figure 2. A more detailed description of the field exploration program is presented in Appendix A. • G e o E n g i n e e r s 2 File No. 0894-132-00\012302 • LABORATORY TESTING Soil samples were collected during the drilling of the four borings and were taken to our laboratory for further examination. Selected samples were tested for grain sizes distribution and moisture content. A description of the laboratory testing and the test results are presented in Appendix B. SITE CONDITIONS GEOLOGY Geologic information for the project vicinity was obtained from the map entitled "Geologic Map of the Renton Quadrangle, King County, Washington" (Mullineaux, 1965). Renton 1 Formation Sandstone and glacial till deposits are mapped in the project vicinity. The sandstone typically consists of very dense friable cemented sand. The glacial till typically consists of medium dense to very dense non-stratified deposits of silty sand with gravel and occasional a cobbles and boulders. The till has been glacially overridden, but the upper 2 to 5 feet is often weathered and is typically medium dense to dense. The glacial till grades to dense to very dense below the weathered zone. iru GEOLOGIC HAZARDS We reviewed the City of Renton Sensitive Areas Maps to evaluate the geologic hazards for the project vicinity. The project site is not located within an identified seismic or coal mine hazard area. However, the site is located in mapped erosion, steep slope and landslide hazard areas. The steep slope present at the site was created by cut slopes made to construct the roadway providing access to the nearby apartment complex and residential property. The Olympic Pipe • Line fuel products pipe line is located near the crest of the slope. In order to gain access to the ,i � pipe, Olympic Pipe Line Company is planning to build a retaining wall near the toe of this steep i� slope (along the shoulder of the access road). The design and construction of this retaining wall is the focus of this report: Once the retaining wall is constructed, the steep slope and landslide hazards at the site will be substantially mitigated. Likewise, the erosion hazard will also be improved. SEISMICITY General Seismicity in the Puget Sound area is primarily driven by the Cascadia Subduction Zone, 1 , which is the zone where the westward advancing North American Plate is overriding the subducting Juan de Fuca Plate. Three potential seismic source zones are generally acknowledged for the Puget Sound area: (1) shallow crustal earthquakes associated with known and/or unknown faults; (2) Cascadia Subduction Zone interface earthquakes, which occur along the boundary located between the Juan de Fuca and North American plates; and (3) Cascadia Subduction Zone i ' intraplate earthquakes,which occur within the subducting Juan de Fuca Plate. G e o Engineers 3 File No. 0894-132-00\012302 • Li Shallow Crustal Earthquakes LShallow crustal earthquakes occur within the North American Plate to depths up to 15 miles. Shallow earthquakes in the Puget Sound region are expected to have durations ranging up to 60 seconds. Four magnitude 7 or greater known earthquakes have occurred in the last 1,100 years in the Cascadia region, two of these occurred on Vancouver Island and two in Western Ti Washington. The largest historic earthquake in Western Washington occurred in 1872 in the North Cascades and is estimated to have had a magnitude of 7.4. This earthquake is believed to have occurred at a depth of less than 10 miles. The other magnitude 7+ Western Washington earthquake occurred on the Seattle Fault approximately 1,100 years ago. „ Shallow crustal faults with known or suspected Quaternary displacements within the general project area include the Seattle Fault, located approximately 8 miles from the site. The Seattle Fault is an east-west trending structure extending from Bainbridge Island, below Seattle, and roughly following the I-90 corridor to the east of Bellevue. Similar shallow faults have been t. identified in the Puget Sound region but have not been studied in detail to date. Interface Earthquakes Interface earthquakes occur on the boundary between the Juan de Fuca and North American tectonic plates. The Cascadia Subduction Zone extends from Vancouver Island to Northern California. Interface earthquakes on the Cascadia Subduction Zone are anticipated to have durations ranging up to 4 minutes. Evidence of the occurrence of large (magnitude 8 to 9+) earthquakes occurring on the Cascadia Subduction Zone has recently been discovered. The last large interface earthquake is believed to have occurred in the year 1700. It is estimated that the recurrence interval for interface earthquakes on the Cascadia Subduction Zone is about 400 to 600 years, however, the interval between earthquakes appears irregular. Intraplate Earthquakes Cascadia Subduction Zone intraplate earthquakes occur within the subducting Juan de Fuca Plate at depths of 30 to 40 miles within the Puget Sound area. Intraplate earthquakes are expected to have durations ranging up to 30 seconds and magnitudes ranging up to 7.5. The Olympia 1949 (magnitude 7.1), the Seattle 1965 (magnitude 6.5), and the Nisqually 2001 (magnitude 6.8) were intraplate earthquakes. I SURFACE CONDITIONS The project site is located within a utility easement used by OPLC and PSE located adjacent to Benson Road just South of I-405. The area to the north and northeast consists of residential ' development and a large apartment complex. A professional building and an assisted living facility are located south and southeast of the easement respectively. An access road leading to the apartment complex is located adjacent to the utility easement on the north side. PSE's use of the easement consists of overhead power transmission lines while OPLC utilizes the easement for t_ an underground fuel products pipe line. f . G e o E n g i n e e r s 4 File No. 0894-132-00\012302 I ire The site is located on a sloping portion of the ridge on the east side of the Green River Valley. The ridge slopes moderately downward toward the west. The topography in the vicinity { of the project is locally variable. There are steep slopes with heights ranging from 15 to 20 feet. } Vegetation in the immediate vicinity of the utility easement includes coniferous and deciduous trees, blackberry bushes, various grasses and some ornamental landscaping. There are no surface water features observed in the immediate vicinity of the project site. SUBSURFACE CONDITIONS General Three general soil types were encountered in the explorations: fill, glacial till and bedrock. The fill overlies glacial till and bedrock. The soil units are discussed in more detail below, beginning with the most recently deposited. Fill Fill was encountered in each of the four borings. The fill generally consists of loose to medium dense silty sand with variable gravel and organic matter content. The thickness of the fill ranges from 3 to 6 feet below the ground surface. Glacial Till- Glacial till was encountered below the fill in borings B-3'and B-4. The glacial till observed generally consists of very dense silty sand with occasional gravel. The thickness of the glacial till layer, where present, varied from 9 to 17 feet and began approximately 6 feet below the ground 6 surface. It is important to note that cobbles and boulders are frequently encountered in glacially deposited soils. While not observed in our,borings, occasional cobbles and boulders are likely lv, contained within the glacial till unit. Bedrock I Bedrock was encountered in each of the four borings and consisted of friable sandstone. The _� .sandstone observed generally consists of very dense silty cemented sand. Each of the four L. borings was terminated in this geologic unit. The sandstone was observed in boring B-1 and B-2 approximately 3 feet below the ground. The sandstone was observed at 15 and 23 feet below the surface in borings B-3 and B-4, respectively. We were able to drill 13 to 23 feet into the sandstone with a CME 45C drill rig using hollow-stem auger drilling equipment. 1 Ground Water Conditions While groundwater was not observed in the borings, zones of perched ground water are frequently encountered in cleaner lenses within the glacial till soils and are expected at this site. Ground water at the site is expected to vary as a function of season, precipitation and other factors.

The key geotechnical issues for the project are: . • We recommend that a soldier pile wall be constructed to provide access to the pipe line. We - evaluated the use of alternative retaining wall systems, including gravity retaining walls and f_ structural earth walls and have concluded that the construction of these systems is not feasible ! due to the proximity of the pipe line and the existing access road. A soldier pile can be constructed near the toe of the existing steep cut slope located between the pipe line ( l alignment and the access road. Depending upon the final geometry of the wall, the soldier pile wall may be constructed as a cantilever wall or with a single row of tiebacks. If tiebacks are used,the tiebacks should be inclined at an angle such that at a 10 foot minimum clearance is maintained between the tiebacks and the pipe line. • We recommend that a drainage blanket consisting of a 12 inch thick layer of quarry spalls be placed on the existing slope between the soldier pile wall and the pipe line alignment. The quarry spall layer should be covered with a needle-punched non-woven geotextile such as Mirafi 180N, or equivalent approved by the geotechnical engineer. The purpose of the quarry spall layer is to provide drainage for the fill soils to be placed behind the soldier pile wall. By incorporating the drainage layer into the wall design, the silty on-site soils can be used as backfill behind the retaining wall, thus reducing the amount of imported backfill and exported unsuitable soils. • No settlement sensitive structures are anticipated to be founded in the backfill for the r retaining structure; therefore, stringent compaction criteria is not warranted for the backfill. The existing pipe line is located outside of the proposed backfill zone. The backfill placed behind the wall should be placed with an excavator to reduce the potential for damage to the drainage layer and geotextile. The backfill should be compacted to at least 85 percent of the maximum dry density as described below. These geotechnical issues and other considerations are discussed further and recommendations pertaining to the geotechnical aspects of the project are presented in the following sections. ( i EARTHWORK . Excavation Considerations. Fill, glacial till and bedrock were observed in the explorations. We anticipate that these materials can be excavated with conventional excavation equipment, such as trackhoes or dozers. -.I It may be necessary to rip the glacial till and bedrock locally to facilitate excavation. Cobbles and boulders typically exist within the glacial till, and the contractor should be prepared to deal with them. G e o E n g i n e e r s 6 File No. 0894-132-00\012302- rr-, Clearing and Grubbing In locations where fill will be placed,we recommend that blackberry bushes and other shrubs be stripped to within six inches of the ground surface. We recommend that the existing topsoil and rootmass be undisturbed in order to reduce the potential for destabilizing the slope. Erosion and Sedimentation Control Potential sources or causes of erosion and sedimentation depend upon construction methods, - slope length and gradient, amount of soil exposed and/or disturbed, soil type, construction j sequencing and weather. The project impact on erosion-prone areas can be reduced by implementing an erosion and sedimentation control plan. The plan should be designed in accordance with applicable city and/or county standards. The plan should incorporate basic 1�I planning principles including: L_: • Scheduling grading and construction to minimize soil exposure. r • Retaining existing vegetation whenever feasible. • Revegetating or mulching denuded areas. • Directing runoff away from denuded areas. • Minimizing the length and steepness of slopes with exposed soils. • Decreasing runoff velocities. • Preparing drainage ways and outlets to handle concentrated or increased runoff. • Confining sediment to the project site. • Inspecting and maintaining control measures frequently. In addition, we recommend that slope surfaces with exposed or disturbed soil be restored so that surface runoff does not become channeled. Some sloughing and raveling of slopes with exposed or disturbed soil should be expected. Temporary erosion protection should be used and maintained in areas with exposed or disturbed soils to help minimize erosion and reduce transport of sediment to adjacent areas and receiving waters. Permanent erosion protection should be provided by re-establishing vegetation by hydroseeding or landscape planting. Until the permanent erosion protection is established and the site is stabilized, site monitoring should be performed by qualified personnel to evaluate the effectiveness of the erosion control measures and repair and/or modify them as appropriate. Provisions for modifications to the 1 erosion control system based on monitoring observations should be included in the erosion and sedimentation control plan. ( `! Structural Fill Materials. Materials used to construct the soldier pile wall drainage layer, placed behind retaining structures or placed as base course below pavements is classified as structural fill for the purpose of this report. Structural fill material quality varies depending upon its use as described 1 1 below: l - 1. Structural fill placed as drainage layer material on the existing steep cut slope should meet the criteria for quarry spalls, WSDOT Standard Specification 9-13.6. r-, G e o E n g i n e e r s - '7 File No. 0894-132-00\012302 f, 2. Structural fill placed as backfill behind the soldier pile wall should meet the criteria for I common borrow, WSDOT Standard Specification 9-03.14(3). 3. Structural fill placed as crushed surfacing base course below pavements should meet WSDOT Standard Specification 9-03.9(3). On-site Soils. The existing fill, glacial till soils and bedrock observed in the explorations generally contain a high percentage of fines (silt) and are highly moisture-sensitive. The on-site soils meet the criteria for common borrow and are suitable for use as backfill behind the soldier 1 pile wall during dry weather construction. The on-site soils will not likely meet the compaction criteria if placed during wet weather. See the "Weather Considerations" section of this report for recommendations regarding use of on-site soils and wet weather conditions. Fill Placement and Compaction Criteria. Structural fill should be mechanically compacted to a firm, nonyielding condition. The structural fill should be placed in lifts. The lift - thickness should sufficiently thin so that following compaction, the entire lift meets the compaction criteria recommended below. The lift thickness should not exceed 2 feet. Each lift should be conditioned to the proper moisture content and compacted to the specified density before placing subsequent lifts. Structural fill should be compacted to the following criteria: 1. Structural fill for drainage layer consisting of quarry spalls should be placed with the bucket 1 of the excavator and tamped into place so that the surface of the drainage layer following placement is relatively flat and uniform. This placement method will reduce the stresses on the geotextile placed above the drainage layer. 2. Structural fill placed behind the soldier pile wall should be compacted to at least 85 percent of the maximum dry density (MDD) per ASTM D-1557. Care should be taken when compacting fill against the soldier pile wall to avoid overcompaction and hence overstressing the wall, for example, by using hand-operated mechanical compaction equipment. Further, care should be taken when placing and compacting the soldier pile wall backfill to minimize the damage to the geotextile and drainage layer. It will likely be necessary to place the fill behind the soldier pile wall with the bucket of the excavator in order to limit the stresses on the geotextile. Fill should not be pushed down the drainage layer with a dozer. 3. Structural fill placed for crushed surfacing base course below pavements should be r ` compacted to at least 95 percent of the MDD per ASTM D-1557. j We recommend that a representative from our firm be present during placement of the structural fill. Our representative will evaluate the contractor's methodology to ensure that the wall construction meets the intent of the design. Our representative will also perform in-place moisture-density tests in the fill to evaluate if the work is being done in accordance with the I-_ compaction specifications, and advise on any modifications to procedure which may be appropriate for the prevailing conditions. G e o E n g i n e e r s 8 File No. 0894-132-00\012302 • T r__ y Weather Considerations. The on-site soils contain a sufficient percentage of fines (silt and clay)to be highly moisture sensitive. When the moisture content of these soils is more than a few percent above the optimum moisture content, these soils become muddy and unstable, operation of equipment on these soils will be difficult and it will be difficult or impossible to meefthe required compaction criteria. Additionally, disturbance of near surface soils should be expected if earthwork is completed during periods of wet weather. It will be preferable to schedule site preparation and earthwork activities during extended periods of dry weather when the soils will (1) be less susceptible to disturbance, (2) provide better support for construction equipment, and (3)more likely to meet the required compaction criteria. The wet weather season generally begins in October and continues through May in the Puget r-- Sound region; however, periods of wet weather may occur during any month of the year. The optimum earthwork period for these types of soils is typically June through September. If wet weather earthwork is unavoidable,we recommend that: 1 • The ground surface in and around the work area should be sloped so that surface water is J' directed away from the work area. The ground surface should be graded such that areas of ( ponded water do not develop. Measures should be taken by the contractor to prevent surface water from collecting in excavations and trenches. Measures should be implemented to remove surface water from the work area. • Earthwork activities should not take place during periods of heavy precipitation. • Slopes with exposed soils should be covered with plastic sheeting or similar means. t • The contractor should take necessary measures to prevent on-site soils and soils to be used as I__ fill from becoming wet or unstable. These measures may include the use of plastic sheeting, sumps with pumps, and grading. The site soils should not be left un-compacted and exposed to moisture. Sealing the surficial soils by rolling with a smooth-drum roller prior to periods of precipitation will reduce the extent that these soils become wet or unstable. • Construction and foot traffic should be restricted to specific areas of the site, preferably areas that are surfaced with materials not susceptible to wet weather disturbance. • Construction activities should be scheduled so that the length of time that soils are left I exposed to moisture is reduced to the extent practical. Temporary Slopes We recommend temporary slopes constructed in the dense to very dense glacial till soils and bedrock be inclined no steeper than 3/4H:1V .(horizontal to vertical). Temporary cut slopes constructed in the loose to medium dense fill and weathered glacial till should be inclined no steeper than 1'/2H:1 V. Flatter slopes may be necessary if seepage is present on the face of the cut slopes or if localized sloughing occurs. For open cuts at the site we recommend that: • No traffic, construction equipment, stockpiles or building supplies be allowed at the top of the cut slopes within a distance of at least 5 feet from the top of the cut. • Exposed soil along the slope be protected from surface erosion using waterproof tarps or visqueen i_ G e o E n g i n e e r s 9 File No. 0894-132-00\012302 Ji • • • Construction activities should be scheduled so that the length of time the temporary cut is left open is reduced to the extent practical. • • Erosion control measures be implemented as appropriate such that runoff from the site is reduced to the extent practical. • Surface water is diverted away from the excavation. • The general condition of the slopes be observed periodically by a geotechnical engineer to confirm adequate stability. . Since the contractor has control of the construction operations, the contractor should be made responsible for the stability of cut slopes, as well as the safety of the excavations. All shoring and temporary slopes must conform to applicable local, state and federal safety regulations. Permanent Slopes We recommend that permanent cut and fill slopes be constructed no steeper than 2H:1V. To achieve uniform compaction, we recommend that fill slopes be overbuilt slightly and subsequently cut back to expose properly compacted fill. To minimize erosion, newly constructed slopes should be planted or hydroseeded shortly after completion of grading. Until the vegetation is established, some sloughing and raveling of the slopes should be expected. This may require localized repairs and reseeding. Temporary covering, such as clear heavy plastic sheeting,jute fabric, loose straw or excelsior matting should be used to protect the slopes during periods of rainfall. SOLDIER PILE WALLS General { We recommend that a soldier pile wall be constructed to provide access to the pipe line. We evaluated the use of alternative retaining wall systems, including gravity retaining walls and structural earth walls, and have concluded that the construction of these systems is not feasible due to the proximity of the pipe line and the existing access road. A soldier pile can be constructed near the toe of the existing steep cut slope located between the pipe line alignment and the access road. Depending upon the.final geometry of the wall, the soldier pile wall may be constructed as a cantilever wall or with a single row of tiebacks. If tiebacks are used,the tiebacks should be inclined at an angle such that at a 10 foot minimum clearance is maintained between the tiebacks and the pipe line. Soldier Piles We recommend that the soldier pile walls be designed using the earth pressure diagrams r, presented in Figures 3 through 6. Figures 3 and 5 should be used for cantilever soldier pile walls with level ground and ground sloped at 2H:1V behind the wall, respectively. Figures 4 and 6 should be used for design of soldier pile walls with tiebacks with level ground and ground sloped at 2H:1V behind the wall, respectively. G e o E n g i n e e r s 10 File No. 0894-132-00\012302 r In Figures 3 and 4, an excavator surcharge pressure and a seismic pressure are presented along with the active/apparent earth pressure and the passive pressure. For the level backslope condition, the wall should be designed for a temporary construction condition and for a I permanent condition. For the temporary construction condition, the wall should be capable of resisting the following: excavator surcharge pressure and active/apparent earth pressure. For the permanent condition, the wall should be capable of resisting the following: seismic pressure and active/apparent earth pressure. In Figures 5 and 6, a seismic pressure is presented along with the active/apparent earth pressure and the passive pressure. For the 2H:1 V backslope condition, the wall should be designed for the permanent condition as surcharge loading is not anticipated in the failure wedge for the temporary construction condition. For the permanent condition, the wall should be capable of resisting the following: seismic pressure and active/apparent earth pressure. It is important to note that the temporary construction condition design is based on the assumption that stockpiles will not be situated between the pipeline and the wall. All stockpiles should be placed south of the pipeline alignment. We recommend that the embedded portion of the holes for the soldier piles be at least 2 feet - J in diameter and extend a minimum distance of 10 feet below the base of the excavation to resist "kick-out." The axial capacity of the soldier pile must resist downward components of tieback loads and other vertical loads, as appropriate. We recommend using an allowable end-bearing value of 15 kips per square foot (ksf) for piles supported in the very dense sandstone bedrock. The allowable end bearing value should be applied to the base area of the drilled hole into which the solider pile is placed. This value includes a factor of safety of a least 2.5. For this site, the soldier piles should be backfilled with structural concrete below the base of the excavation. As the wall will be constructed as a fill wall, no lean-mix concrete is anticipated l to be required for the portion of the pile located above the base of the excavation. Lagging We recommend that the lagging be designed for uniform pressures equal to one-half the lateral pressure presented in Figures 3 through 6. This pressure reduction is based on a maximum center-to-center pile spacing of 8 feet. Timber lagging should be a minimum of 3 inches thick. If a wider spacing is desired, we should be consulted for revised lagging pressures. A gap should exist between each lagging timber of approximately 1/8-inch to 1/4-inch to allow water to pass through the lagging. Tiebacks Tieback anchors are typically required where wall heights exceed about 12 to 15 feet, depending upon backslope inclination and surcharge loading. The tiebacks should extend far enough behind the wall to develop anchorage beyond the "no-load" zone and into a stable soil mass as depicted in Figures 4 and 6. As a minimum, the anchors should extend at least 10 feet beyond the no-load zone. The "no-load" zone is defined by a line extending horizontally back G e o E n g i n e e r s 11 File No. 0894-132-00\0(2302 from the wall at the base of the excavation for a distance equal to H/4, where H is the height of the wall, and then extending upward and away from the wall at an angle of 60 degrees, measured from the horizontal. The anchors should be inclined downward at 15 to 30 degrees below the horizontal. The tiebacks, if necessary, should be designed to have a minimum 10-foot clearance between • the existing OPLC pipe line. We recommend that the tieback anchors be designed and constructed in general accordance with the criteria presented in the following documents: 1. U.S. Department of Transportation, Federal Highway Administration, "Permanent Ground Anchors," Report FHWA-DP-68-1R, 1984. 2. U.S. Department of Transportation, Federal Highway Administration, "Tiebacks," Report FHWA/RD-82/047, 1982. 3. Post Tensioning Institute, "Recommendations for Prestressed Rock and Soil Anchors," 1995. Tiebacks should develop anchorage in the very dense glacial till or sandstone bedrock. We estimate that a design load transfer of 4 kips/foot can be achieved in the site soils. However, the _ contractor shall select a design load transfer value that is appropriate for the drilling equipment, __ drilling methods, and borehole diameter. We recommend that spacing between tiebacks be at least 3 times the anchor hole diameter to reduce the potential for group interaction. The tieback anchors should be performance and proof tested generally as described in the above-referenced Post Tensioning Institute publication. At least two anchors must be performance tested to 200 percent of the design load in each soil type to verify that the design load transfer can be achieved prior to installing production anchors. The capacity of each production anchor should be proof tested by loading to 1.3 times the design load and holding for a minimum of 10 minutes as described in the above references. Drainage We recommend that a drainage blanket consisting of a 12 inch thick layer of quarry spalls be placed on the existing slope between the soldier pile wall and the pipe line alignment. The quarry spall layer should be tamped into place such that the surface of the quarry spall layer is relatively smooth and even. The quarry spall layer should then be covered with a needle-punched non- woven geotextile such as Mirafi 180N, or equivalent approved by the geotechnical engineer. Measures should be taken to prevent the geotextile from being damaged during placement of backfill behind the soldier pile wall. These measures may include extending the geotextile t-- upslope and placing a soil berm over the geotextile to anchor it, and placing the backfill with an excavator and filling from the bottom up in horizontal lifts. The purpose of the quarry spall layer is to provide drainage for the fill soils to be placed behind the soldier pile wall. By incorporating the drainage layer into the wall design,the silty on- site soils can be used as backfill behind the retaining wall, thus reducing the amount of imported backfill and exported unsuitable soils. G e o E n g i n e e r s 12 File No. 0894-132-00\012302 In addition to the quarry spall drainage blanket, measures should be implemented to prevent the buildup of hydrostatic pressures behind the soldier pile and lagging wall. If timber board lagging is used, drainage may be achieved by spacing the boards with a vertical gap of approximately 1/8 to 1/4 inch. Wick drains or strips of composite drainage material should also be installed behind the lagging. The strip drains should be at least 18-inches wide and extend the entire height of the wall. The strip drains should be installed between each soldier pile. If no concrete facing is constructed in front of the wall, we recommend that the strip drains extend down into the quarry spall drainage blanket and the water collected in the strip drains and drainage blanket be allowed to weep through the timber lagging. If a concrete facing is constructed in front of the wall, we recommend that the strip drains be connected to a perforated drain installed along the base of the wall that is connected to the storm drainage system. The - - perforated drain should be connected to a solid tightline pipe that discharges to a storm water -- drainage system. • Surface water should not be allowed to infiltrate immediately behind the soldier pile walls. Surface water should be directed away from the soldier pile walls using constructed berms and/or swales or the ground surface should be sloped behind the wall to reduce the amount of water that infiltrates. The contractor should be responsible for constructing and maintaining the surface water collection system to direct surface water away from the soldier pile wall. ri Construction Considerations Temporary Casing. Temporary casing may be required in the near surface soils to prevent caving. As sandstone bedrock was encountered within 5 feet of the existing ground surface in the borings completed along the proposed wall alignment, temporary casing is not anticipated to be • necessary at depth. Since the contractor has control of the construction operations, the contractor should be made responsible for determining when temporary casing is necessary to protect existing structures and to ensure site safety. Dewatering and Tremie Placement. No attempt should be made to dewater the soldier pile holes. If ground water is present at the base of the excavation prior to concrete placement, the concrete should be placed using tremie techniques. If ground water is encountered and the excavation is not cased to full depth, the water level in the excavation must be maintained at the level of the surrounding ground surface during soldier pile construction.•The contractor must also be prepared to control blow-ins at the bottom of the excavation. j Obstructions/Bedrock Drilling. It is likely that cobbles and boulders will be encountered in the on-site soils. Core drilling or excavation with a backhoe may be required to remove cobbles and/or boulders. ( Borings completed for this study were drilled with a hollow stem auger; therefore, we anticipate that the sandstone bedrock can be drilled using a drill rig capable of installing soldier piles in very dense granular soils, such as glacial till. The drill rig must be capable of applying - sufficient down pressure to advance the soldier pile excavations. We strongly recommend that a • G e o E n g i n e e r s• 13 File No. 0894-132-00\012302 drilling specialty subcontractor with the proper drilling equipment and experience be considered to install the soldier piles and tiebacks, if necessary. L, Utilities. The contractor should verify the location and depth of all utilities, including the OPLC fuel products pipe line, prior to commencing earthwork activities. It should be noted that the PSE overhead power transmission lines are located directly above the wall alignment; therefore, the contractor should utilize proper equipment and procedures to install the soldier piles. Conflicts between the design drawings and the location of existing utilities should be brought to the attention of the engineer. Safety Fence. A chain link fence should be constructed along the face of the wall to reduce the potential for workers, passersby and equipment from falling,off the wall. Access Requirements. The existing access road to the nearby residences and the apartment complex will likely be closed to through traffic during construction of the wall. Therefore, agreements must be obtained from PSE and the parties that rely on the access road to close the road temporarily in order to construct the retaining wall. Further, there is limited space between the pipe line and the adjacent properties to the south. It is anticipated that an agreement will be necessary with the property owner to the south of the utility alignment to gain temporary access during construction and to complete minor grading,as necessary. Pavement repair. The existing access road will likely be damaged by construction equipment. The existing pavement section may need to be replaced in some areas. We recommend that the new pavement section match the existing pavement section in new pavement • areas. Alternatively, an overlay may be required to repair construction related damage to the existing roadway pavement.

The explorations were completed to depths ranging from 25 to 36 feet below the existing ground surface. The drilling was performed by Gregory Drilling on November 27, 2001. The locations of the } explorations were estimated by measuring distances from site features through taping/pacing in the field, and should be considered approximate. Ground surface elevations at the exploration locations were estimated from the topographic map prepared by Reid Middleton for this project and should be considered approximate. The locations of the explorations are shown on the.Site Plan, Figure 1. - Z BORINGS The borings were completed using hollow stem auger drilling techniques and a CME 45C T track mounted rig. The borings were continuously monitored by an engineering geologist from our firm who examined and classified the soils encountered, obtained representative soil samples, observed ground water conditions, and prepared a detailed log of each exploration. 1_,'' Representative soil samples were obtained from the borings at selected depths using a 1.375-inch- inside-diameter split-barrel sampler driven into the soil using a 140-pound automatic hammer free-falling a vertical distance of 30 inches. The number of hammer blows (blows per foot) required to drive the sampler the final 12 inches, or other indicated distance, is recorded on the boring logs. Soils encountered in the borings were visually classified in general accordance with the classification system described in Figure A-1. A key to the boring log symbols is presented in Figure A-2. The logs of the borings are presented in Figures A-3 to A-6. The boring logs are based on our interpretation of the field and laboratory data and indicate the various types of soils and ground water conditions encountered. The logs also indicate the depths at which these soils or their characteristics change, although the change may actually be gradual. If the change occurred between samples, it was interpreted. The densities noted on the boring logs are based on the blow count data obtained in the borings and judgement based on the conditions observed. Observations of ground water conditions were made during drilling. The ground water conditions encountered during drilling are presented on the boring logs. Ground water conditions observed during drilling represent a short term condition and may or may not be representative of the long term ground water conditions at the site. Ground water conditions observed during drilling should be considered approximate. n 6 G e o E n g i n e e r s A-1 File No. 0894-132-00\012302 trl SOIL CLASSIFICATION SYSTEM 1�i � L GROUP MAJOR DIVISIONS SYMBOL GROUP NAME GW WELL-GRADED GRAVEL,FINE TO COARSE GRAVEL GRAVEL CLEAN GRAVEL i COARSE GP POORLY-GRADED GRAVEL ) GRAINED More Than 50% SOILS of Coarse Fraction GM SILTY GRAVEL GRAVEL Retained on No.4 Sieve WITH FINES GC CLAYEY GRAVEL SW WELL-GRADED SAND,FINE TO COARSE SAND SAND CLEAN SAND ( More Than 50% SP POORLY-GRADED SAND Retained on More Than 50% SM • SILTY SAND No.200 Sieve of Coarse Fraction SAND Passes WITH FINES SC CLAYEY SAND 1114 i No.4 Sieve ML SILT FINE SILT AND CLAY INORGANIC GRAINED CL CLAY SOILS Liquid Limit ORGANIC OL ORGANIC SILT,ORGANIC CLAY Less Than 50 MH SILT OF HIGH PLASTICITY,ELASTIC SILT More Than 50% SILT AND CLAY INORGANIC j Passes CH CLAY OF HIGH PLASTICITY,FAT CLAY No.200 Sieve LiquidlLimit 50 or More ORGANIC OH ORGANIC CLAY,ORGANIC SILT HIGHLY ORGANIC SOILS PT PEAT NOTES: SOIL MOISTURE MODIFIERS: 1 Y 1.

Representative samples were selected for laboratory testing consisting of moisture content testing and grain size analyses testing. The tests were performed in general accordance with test methods of the American Society for Testing and Materials (ASTM) or other applicable procedures. The results of the grain size analyses tests are presented in Figures B-1. The results of the moisture content tests are presented on the exploration logs at the respective sample depths in Appendix A. r MOISTURE CONTENT TESTING Moisture contents tests were completed in general accordance with ASTM D 2216 for representative samples obtained from the explorations. The results of these tests are presented on the exploration logs in Appendix A at the depths at which the samples were obtained. GRAIN-SIZE ANALYSES Grain-size analyses were performed on selected samples in general accordance with ASTM D 422. The wet sieve analysis method was used to estimate the percentage of soil greater than the U.S.No.200 mesh sieve. The results of the particle size analyses were plotted, classified _ in general accordance with the Unified Soil Classification System, and presented in Figure B-1. i ' G e o E n g i n e e r s B-1 File No. 0894-132-00\012302 0894-132-00 MWS:JVJ:jvj 12-06-01 (Sieve.ppt) U.S. STANDARD SIEVE SIZE 3" 1.5" 3/4" 3/8" #4 #10 #20 #40 #60 #100 #200 0 100.0 1 I I 1 I I I I I I 1 " I I III I II III I I I I 90.0 I I IIIII 11 i 11 1 11 11 I I ��11/a 11 (9 1 I 1 1 1 1 1 1 1 1 1 1 , 1 III 1 1 I 1sN�� oo II I I l II I 1 I I I I I I 11 I I , 70.0 I I I I H m 60.0I - IIII CD III 1 I II 1 11 1 1 . 1 1 1 CD 1 : 11 , I I 111 Iil IIIII30.0 1 � 11 I 1 1 I I - � 20.0 II 11 1I 11 1 I I� I I I I I I I I I .

GEOTECHNICAL SERVICES ARE PERFORMED FOR SPECIFIC PURPOSES, PERSONS AND PROJECTS This report has been prepared for use by the Olympic Pipe Line Company and their design team members. This report is not intended for use by others, and the information contained herein is not applicable to other sites. GeoEngineers structures our services to meet the specific needs of our clients. For example, a geotechnical or geologic study conducted for a civil engineer or architect may not fulfill the needs of a construction contractor or even another civil engineer or architect that are involved in the same project. Because each geotechnical or geologic study is unique, each geotechnical engineering or geologic report is unique, prepared solely for the specific client and project site. No one except the Olympic Pipeline Company should rely on this report without first conferring with GeoEngineers. This report should not be applied for any purpose or project except the one originally contemplated. A GEOTECHNICAL ENGINEERING OR GEOLOGIC REPORT IS BASED ON A UNIQUE SET OF PROJECT-SPECIFIC FACTORS This report has been prepared for the OPLC Milepost 111.4 site in Renton, Washington. GeoEngineers considered a number of unique, project-specific factors when establishing the scope of services for this project and report. Unless GeoEngineers specifically indicates otherwise, do not rely on this report if it was: • not prepared for you, { • not prepared for your project, { • not prepared for the specific site explored, or II` • completed before important project changes were made. For example, changes that can affect the applicability of this report include those that affect: • the function of the proposed structure; • elevation, configuration, location, orientation or weight of the proposed structure; • composition of the design team; or • project ownership. If important changes are made after the date of this report, GeoEngineers should be given the opportunity to review our interpretations and recommendations and provide written modifications or confirmation, as appropriate. L_, Developed based on material provided by ASFE,Professional Firms Practicing in the Geosciences;www.asfe.org. GeoEngineers C-1 File No. 0894-132-00\012302 SUBSURFACE CONDITIONS CAN CHANGE This geotechnical or geologic report is based on conditions that existed at the time the study was performed. The findings and conclusions of this report may be affected by the passage of time, by manmade events such as construction on or adjacent to the site, or by natural events such as floods, earthquakes, slope instability or ground water fluctuations. Always contact GeoEngineers before applying a report to determine if it remains applicable. MOST GEOTECHNICAL AND GEOLOGIC FINDINGS ARE PROFESSIONAL OPINIONS Our interpretations of subsurface conditions are based on field observations from widely spaced sampling locations at the site. Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers reviewed field and laboratory data and then applied our professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ, sometimes significantly, from those indicated in this report. Our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. - GEOTECHNICAL ENGINEERING REPORT RECOMMENDATIONS ARE NOT FINAL Do not over-rely on the preliminary construction recommendations included in this report. These recommendations are not final, because they were developed principally from GeoEngineers' professional judgment and opinion. GeoEngineers' recommendations can be finalized only by observing actual subsurface conditions revealed during construction. GeoEngineers cannot assume responsibility or liability for this report's recommendations if we do not perform construction observation. Sufficient monitoring, testing and consultation by GeoEngineers should be provided during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork activities are completed in accordance with our recommendations. Retaining GeoEngineers for construction observation for this project is the most effective method of managing the risks associated with unanticipated conditions. A GEOTECHNICAL ENGINEERING OR GEOLOGIC'REPORT COULD BE SUBJECT TO MISINTERPRETATION Misinterpretation of this report by other design team members can result in costly problems. You could lower that risk by having GeoEngineers confer with appropriate members of the _ l design team after submitting the report. Also retain GeoEngineers to review pertinent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering or geologic report. Reduce that risk by having GeoEngineers participate in pre-bid and preconstruction conferences, and by providing construction observation. GeoEngineers C-2 File No. 0894-132-00\012302 DO NOT REDRAW THE EXPLORATION LOGS Geotechnical engineers and geologists prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included • in a geotechnical engineering or geologic report should never be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk. • GIVE CONTRACTORS A COMPLETE REPORT AND GUIDANCE • Some owners and design professionals believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give contractors the complete geotechnical engineering or geologic report, but preface it with a clearly written letter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is • limited; encourage them to confer with GeoEngineers and/or to conduct additional study to obtain the specific types of information they need or prefer. A pre-bid conference can also be valuable. Be sure contractors have sufficient time to perform additional study. Only then might an.owner be in a position to give contractors the best information available, while requiring them to at least share the financial responsibilities stemming from unanticipated conditions. Further, a contingency for unanticipated conditions should be included in your project budget and schedule. - ' CONTRACTORS ARE RESPONSIBLE FOR SITE SAFETY ON THEIR OWN CONSTRUCTION PROJECTS Our geotechnical recommendations are not intended to direct the contractor's procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to minimize risks to on-site personnel and to adjacent properties. READ THESE PROVISIONS CLOSELY F Some clients, design professionals and contractors may not recognize that the geoscience practices (geotechnical engineering or geology) are far less exact than other engineering and natural science disciplines. This lack of understanding can create unrealistic expectations that 1 i could lead to disappointments, claims and•disputes. GeoEngineers includes these explanatory "limitations" provisions in our reports to help reduce such risks. Please confer with • GeoEngineers if you are unclear how these "Report Limitations and Guidelines for Use" apply to - your project or site. GEOTECHNICAL, GEOLOGIC AND ENVIRONMENTAL REPORTS SHOULD NOT BE INTERCHANGED The equipment, techniques and personnel used to perform an environmental study differ significantly from those used to perform a geotechnical or geologic study and vice versa. For that • reason, a geotechnical engineering or geologic report does not usually relate arpy environmental findings, conclusions or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Similarly, environmental reports are not used to address geotechnical or geologic concerns regarding a specific project. GeoEngineers . C-3 File No. 0894-132.00\012302
