A geotechnical engineering study conducted for a civil engi- neer may not fulfill the needs of a construction contractor or even another civil engineer. Because each geotechnical engineering study is unique, each geotechnical engineering report is unique, prepared solelyfor the client. No one except you should rely on your geotechnical engineering report without first conferring with the geotechnical engineer who prepared it. Andno one — notevenyou —should apply the report for any purpose or project except the one originally contemplated. Read the Full Repopt Serious problems have occurred because those relying on a geotechnical engineering report did not read it all. Do not rely on an executive summary. Do not read selected elements only. - - - I F1 I I I I I A Geotechnical Engineering Report Is Based on A Unique get of Ppoject-Specific Factors Geotechnical engineers consider a number of unique, project -specific fac- tors when establishing the scope of a study. Typical factors include: the client's goals, objectives, and risk management preferences; the general nature of the structure involved, its size, and configuration; the location of the structure on the site; and other planned or existing site improvements, such as access roads, parking lots, and underground utilities. Unless the geotechnical engineer who conducted the study specifically indicates oth- erwise, do not rely on a geotechnical engineering report that was: • not prepared for you, • not prepared for your project, • not prepared for the specific site explored, or • completed before important project changes were made. Typical changes that can erode the reliability of an existing geotechnical engineering report include those that affect: the function of the proposed structure, as when it's changed from a parking garage to an office building, or from a light industrial plant to a refrigerated warehouse, • elevation, configuration, location, orientation, or weight of the proposed structure, • composition of the design team, or • project ownership. As a general rule, always inform your geotechnical engineer of project changes —even minor ones —and request an assessment of their impact. Geolechnical engine6rs cannot accept responsibility or liability for problems that occur because their reports do not consider developments of which they were not informed. Subsurface Conditions Can Change A geotechnical engineering report is based on conditions that existed at the time the study was performed. Do not rely on a geolechnical engineer- ing repottwhose adequacy may have been affected by: the passage of time; by man-made events, such as construction on or adjacent to the site; or by natural events, such as floods, earthquakes, or groundwater fluctua- tions. Always contact the geotechnical engineer before applying the report to determine if it is still reliable. A minor amount of additional testing or analysis could prevent major problems. Most Geotechnical Findings Ape Professional Opinions Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. Geotechnical engi- neers review field and laboratory data and then apply their professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ —sometimes significantly — from those indicated in your report. Retaining the geotechnical engineer who developed your report to provide construction observation is the most effective method of managing the risks associated with unanticipated conditions. A Repopt's Recommendations Ape Not Final Do not overrely on the construction recommendations included in your report. Those recommendations are not final, because geotechnical engi- neers develop them principally from judgment and opinion. Geotechnical engineers can finalize their recommendations only by observing actual I I subsurface conditions revealed during construction. The geotechnical engineer who developed your report cannot assume responsibility or liability for the report's recommendations if that engineer does not perform construction observation, A Geotechnical Engineeping Repopt Is Subject to Misintepppetation Other design team members' misinterpretation of geotechnical engineering reports has resulted in costly problems. Lower that risk by having your geo- technical engineer confer with appropriate members of the design team after submitting the report. Also retain your geotechnical engineer to review perti- nent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering report. Reduce that risk by having your geotechnical engineer participate in prebid and preconstruction conferences, and by providing construction observation. Do Not Redpaw the Engineep's Logs Geotechnical engineers prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical engineering report should never be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk Give Contpactops a Complete Repopt and Guidance Some owners and design professionals mistakenly believe they can make Contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give con- tractors the complete geotechnical engineering report, butpreface 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 the geotechnical engineer who prepared the report (a modest fee may be required) and/or to conduct additional study to obtain the specific types of information they need or prefer. A prebid conference can also be valuable. Be sure contrac- tors have sufficlent time to perform additional study. Only then might you be in a position to give contractors the best information available to you. while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions. Read Responsibility Ppovisions Closely Some clients, design professionals, and contractors do not recognize that geotechnical engineering is far less exact than other engineering disci- plines. This lack of understanding has created unrealistic expectations that have led to disappointments, claims, and disputes. To help reduce the risk of such outcomes, geotechnical engineers commonly include a variety of explanatory provisions in their reports. Sometimes labeled "limitations" many of these provisions indicate where geotechnical engineers' responsi- bilities begin and end, to help others recognize their own responsibilities and risks, Read these provisions closely. Ask questions. Your geotechnical engineer should respond fully and frankly. Geoenviponmental Concepns Ape Not Coveped The equipment, techniques, and personnel used to perform a geoenviron- mental study differ significantly from those used to perform a geotechnical study. For that reason, a geotechnical engineering report does not usually relate any geoenvironmental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated environmental problems have led to numerous project failures. If you have not yet obtained your own geoen- vironmental information, ask your geotechnical consultant for risk man- agement guidance. Do not rely on an environmental report prepared for someone else. Obtain Ppofessional Assistance To Deal with Mold Diverse strategies can be applied during building design, construction, operation, and maintenance to prevent significant amounts of mold from growing on indoor surfaces. To be effective, all such strategies should be devised for the express purpose of mold prevention, integrated into a com_ prehensive plan, and executed with diligent oversight by a professional mold prevention consultant. Because just a small amount of water or moisture can lead to the development of severe mold infestations, a num- ber of mold prevention strategies focus on keeping building surfaces dry. While groundwater, water infiltration, and similar issues may have been addressed as part of the geotechnical engineering study whose findings are conveyed in -this report, the geotechnical engineer in charge of this project is not a mold prevention consultant; none of the services per- formed in connection with the geotechnical engineer's study were designed or conducted for the purpose of mold preven- tion. Proper implementation of the recommendations conveyed in this report will not of itself he sufficient to prevent mold from growing in or on the structure involved.

The purpose of this study was to prepare geotechnical recommendations for the proposed development. Our scope of services for completing this Geotechnical Engineering Study included the following: • Reviewing past subsurface information conducted by Terra Associates, Inc., and; • Preparation of this report As part of our report preparation, pertinent sections of the following documents were reviewed: • Site Plan prepared by Eclipse Design, LLC, Sheet A; • The Geologic Map of the Edmonds East and Part of the Edmonds West Quadrangles, USGS Map MF-1541; Geologically Hazardous Areas Review, prepared by Terra Associates, Inc. Project No. T- 5332, dated February 27, 2003; Geotechnical Engineering Study prepared for 7039 Meadowdale Beach Road completed by Earth Solutions NW, LLC, job ES-0228, dated November 28, 2005; The USDA Soil Conservation Survey (SCS) of Snohomish County, and; City of Edmonds Geologically Hazardous Areas (Chapter 23.80). Proaect Description The site is located off the northern side of Meadowdale Beach Road and near the top of a descending natural slope. The project area is an undeveloped parcel designated Lot 4 in the referenced report by Terra Associates, Inc. prepared in 2003. The proposal includes construction of a two-story single-family residence and associated improvements. The building construction will consist of relatively light wood -framing and conventional foundations. Perimeter and interior continuous footing loads are estimated to be on the order of 1 to 2 kips per lineal foot. Slab loading is estimated to be on the order of 150 pounds per square foot. The building will include a daylight basement/garage configuration. The maximum cuts for the proposed structure foundations will be on the order of ten feet. A rockery facing a cut into native soil will be utilized along the north construction envelope to create a level back yard. We anticipate footings will follow the existing grade to the extent practical in order to minimize disturbance. Given the site configuration and anticipated grading, temporary shoring for excavations will likely not be required. I I Thomas Reilly & Sharon Lin ES-1845 August 31, 2010 Page 2 If the above design assumptions are incorrect or change, ESNW should be contacted to review the recommendations in this report. ESNW should review the final design to verify that our geotechnical recommendations have been incorporated into the design. SITE CONDITIO'NS Surface The site is located on the northeast side of Meadowdale Beach Road in Edmonds, Washington. The approximate location of the subject property is illustrated on the Vicinity Map (Plate 1). The property consists of a single tax approximately 0.25 acres in size. The approximate limits of the property are illustrated on the Test Pit Location Plan (Plate 2). The site consists of a roughly triangular lot which is situated near the crest of a slope with a local high elevation of about 368 feet. The topography across the lot generally descends to the south-southwest with about 50 feet of total elevation change and about 20 feet across the building footprint. The gradient across the proposed footprint is about 50 percent. The site is vacant and vegetated with a relatively mature forest of fir trees. Site History Terra Associates, Inc. prepared the referenced critical areas report in 2003, which included subsurface explorations across the subject and adjacent lots. ESNW prepared a geotechnical engineering study and provided construction monitoring services for the adjacent parcel at 7039 Meadowdale Beach Road. During construction, site soils remained stable and consistent with the conditions reported in the Terra Associates, Inc. report. Subsurface The site was explored during preparation of the referenced Geologically Hazardous Areas report prepared by Terra Associates, Inc. by excavating test pits within the subject lot (Lot 4) and adjoining lot (Lot 3). The approximate locations of the test pit are illustrated on the Test Pit Location Plan (Plate 2). The test pit logs for Lots 3 and 4 are provided in Appendix A. The following is a general description of the.soil conditions encountered at the test sites. In general Lot 4 is underlain by medium dense to dense sand consistent with advance outwash glacial deposits. Soil relative density generally increased with depth. Groundwater was not reported on the test pit logs. Geologic Map and Soil Map Review As part of our report preparation, we reviewed available maps regarding soil conditions for the subject site. The referenced geologic map identifies advance outwash deposits (Qva) across the subject property. Earth Solutions NW, LLC Thomas Reilly & Sharon Lin ES-1 845 August 31, 2010 Page 3 The Soil Survey of Snohomish County identifies Alderwood-Evereft gravelly sandy loam soils (Map Unit 4) 25-70 percent slopes across the site and surrounding area. Alderwood-Evereft gravelly sandy loam series soils formed in glacial till/outwash and erosion hazards are severe for these type soils. Groundwater Groundwater seepage was not reported at the test pit locations during the fieldwork conducted by Terra Associates, Inc. (February 2003). However, localized perched zones of groundwater seepage should be expected in the site excavations. Groundwater seepage rates fluctuate depending on many factors, including precipitation duration and intensity, the time of year, and soil'conditions. In general, groundwater seepage and flow rates are higher during the wetter, winter months. However, zones of persistent or chronic groundwater seepage are not uncommon, and can be encountered during any time of year. CRITICAL AREAS AND GEOLOGIC HAZARDOUS AREAS ASSESSMENT As part of this geotechnical engineering study and critical areas report, we reviewed the City of Edmonds Critical Area Ordinance (Chapter 23.80). Per the City of Edmonds Critical Areas Report requirements, the following topics related to development plans and site conditions are addressed. Site and Construction Plans The attached Test Pit Location Plan (Plate 2) illustrates the proposed building footprint area and local site topography. Construction of a single-family residence is planned for the site. The maximum cuts for the proposed structure foundations will be on the order of ten feet. The overall stability of the steep slope areas can be characterized as good. Assessment of Geological Characteristics The referenced geologic map identifies advanced outwash deposits across the subject property. The native soils encountered at the test pit locations consisted primarily of medium dense to very dense silty sand and poorly graded sand with silt consistent with the geologic map designations. Landslide Hazards With respect to landslide hazard areas, 32.80.02*0 of the Edmonds City Development Code (ECDC) defines landslide hazard areas as slopes of 40 percent or greater with a vertical rise of more than ten feet. The natural slope across the subject site is in excess of 40 percent with a vertical rise of more than ten feet. Overall stability of the slopes can be characterized as good. Typical indicators of instability such as head scarps, tension cracks, hummocky terrain, groundwater seeps along the surface and erosion features such as gulleys and rills were not reported during past site visits. Therefore, in our opinion the sloped areas of the site are stable with respect to landslide activity. Earth Solutions NW, LLC Thomas Reilly & Sharon Lin August 31, 2010 Erosion Hazards ES-1 845 Page 4 With respect to erosion hazard areas, the slope across the site would be severely susceptible to erosion, in our opinion. However, based on our direct experience during the construction of the residence at 7039 Meadowdale Beach Road, the soil will likely remain relatively stable during grading activities. In our opinion, the planned development will not increase the erosion hazard at the site, provided Best Ma ' nagement Practices are implemented during the earthwork and development activities. General guidelines for erosion control are provided in the Site Preparation and Earthwork section of this study. Analysis of Proposal The planned development activity will involve grading and construction of a two-story residential structure within a geologically hazardous area. As previously described, the slope is stable with respect to landslide activity. The proposed development activity is feasible in our opinion, and will not decrease stability of the site or surrounding properties. Minimum Critical Area Buffer and Setback In our opinion, the proposed grading and development activity can be completed as currently planned without additional setback or buffer requirements. The proposed development will not result in an increased potential for landslide activity. This opinion does not cover unforeseen or changed conditions. DISCUSSION AND RECOMMENDATIONS General Based on the results of our study, construction of the two-story single-family residence as planned is feasible from a geotechnical standpoint. The primary geotechnical considerations are associated with foundation support and minimizing impacts to the slope area. In our opinion, the proposed single-family residence can be supported on conventional shallow foundations supported on competent or recompacted native soil or structural fill. We anticipate competent native soil capable of providing foundation support will be encountered at foundation grades for the daylight basement or at depths of between two to four feet below existing grades. Overexcavation may be required under foundation elements depending on the condition during grading activities. A representative of ESNW should be onsite during foundation excavations to confirm conditions are as anticipated and to provide supplemental recommendations for foundation subgrade preparation. In our opinion, the soils generated from cuts throughout the majority of the site may not be suitable for use as structural fill. Moisture conditioning of the on -site soils prior to use as structural fill would likely involve the addition of moisture, where dry soil conditions are encountered or aeration of soils where over -optimum conditions are present. A representative of ESNW should evaluate the suitability of using on -site soils when grading begins. A contingency in the project budget should be included in the event on -site soils are deemed unsuitable by the geotechnical engineer. A representative of ESNW should be on -site during fill placement to confirm that adequate compaction is achieved. Earth Solutions NW, LLC I I I I 11 I I I I I I I 11 I I I I Thomas Reilly & Sharon Lin ES-1845 August 31, 2010 Page 5 This report has been prepared for the exclusive use of Thomas Reilly and Sharon Lin and their representatives. This study has been prepared in a manner consistent with the level of care and skill ordinarily exercised by other members.of the profession currently practicing under similar conditions in this area. Site Preparation and Earthwork Site preparation will likely include removing existing vegetation from the construction envelope including, but not limited to trees, brush and topsoil. Temporary Erosion Control Temporary erosion control measures should include, at a minimum, silt fencing placed along the downslope perimeter of the construction envelope, and a construction entrance consisting of at least 12 inches of quarry spalls should be considered in order to minimize off -site soil tracking and to provide a firm surface. Surface water should not be allowed to flow over temporary or permanent slopes. Interceptor drains or swales should be considered for controlling surface water flow patterns. A representative of ESNW should observe the erosion control measures, and provide supplement recommendations for minimizing erosion during construction, as necessary. If temporary discharge of stormwater offsite is planned during construction, turbidity monitoring should be performed, as required by the City of Edmonds. Excavations Based on the subsurface conditions described in the referenced reports, medium dense to dense silty sand and sand soils are anticipated to be encountered in the planned excavations. The soils anticipated to be encountered in the proposed excavations can be characterized as having of moderate sensitivity to moisture. During periods of extended precipitation, placement and compaction of the excavated soils will be difficult. The presence of localized perched groundwater seepage could be encountered in the planned excavations. A representative of ENSW should observe the excavations, and provide supplement recommendations for drainage, as necessary. In our opinion a contingency should be included in the project budget for imported structural fill. Structural Fill Placement In general, areas to receive structural fill should be sufficiently stripped of organic matter and other deleterious material. The majority of the organic matter associated with trees, brush, root balls, and groundcover should be removed from the proposed fill and cut areas. Structural fill is defined as compacted soil placed in foundation, slab -on -grade, and roadway areas. Fills placed to construct permanent slopes and throughout retaining wall and utility trench backfill areas are also considered structural fill. Soils placed in the building pad areas should be placed in maximum 12-inch loose lifts and compacted to a relative compaction of 90 percent, based on the maximum dry density as determined by the Modified Proctor Method (ASTM D-1 557-02). Earth Solutions NW, LLC I Thomas Reilly & Sharon Lin ES-1845 August 31, 2010 Page 6 I I 11 I I I I I I F] I I I I I I If the on -site soils cannot be successfully compacted, the use of an imported soil may be necessary. Imported soil intended for use as structural fill should consist of a well graded granular soil with a maximum aggregate grain size of four inches, and a moisture content that is at or near the optimum level. During wet weather conditions, imported soil intended for use as structural fill should consist of a well graded granular soil with a fines content of 5 percent or less defined as the percent passing the #200 sieve, based on the minus three-quarter inch fraction. Slope Fill Placement In general, fill placement throughout the existing sloped areas of the site is feasible, provided the existing slope surfaces are benched prior to fill. General guidelines for slope fill placement are provided on Plate 3 of this report. The project geotechnical engineer should be on -site during the fill placement to assess the slope fill construction, and to provide supplement recommendations for the fill placement, as necessary. During the construction of the fill slopes, the slope face must be compacted. Excavations and Slopes The Federal and state Occupation Safety and Health Administration (OSHANVISHA) classifies soils in terms of minimum safe slope inclinations. Based ' on the soil conditions described at the test pit locations, the site soils would generally be classified by OSHANVISHA as Type A. Temporary slopes over four feet in height in Type A soils should be sloped no steeper than 0.75H:1V (Horizontal:Vertical). If temporary slopes cannot be constructed in accordance with OSHANVISHA guidelines, temporary shoring may be necessary. Permanent slopes should maintain a gradient of 2H:1V, or flatter, and should be planted with a species of vegetation to enhance stability and to minimize erosion. A representative of ESNW should observe temporary and permanent slopes to confirm that the slope inclinations are suitable for the exposed soil conditions, and to provide additional grading recommendations, as necessary. Utility Support and Trench Backfill The native soils anticipated to be exposed during utility trench excavations consist of firm sandy deposits. In general, the on -site soils observed at the test sites described in the referenced reports should be suitable for use as structural backfill in the utility trench excavations, provided the soil is at or near the optimum moisture content at the time of placement and compaction. Areas of the onsite soils, however, may not be suited for utility trench backfill, and should be further evaluated by the ESNW at the time of construction. Utility trench backfill should be placed and compacted to the specifications of structural fill provided in this report, or to the specifications of the City of Edmonds, if applicable. Groundwater should be expected in utility trench excavations. I Earth Solutions NW, LLC Thomas Reilly & Sharon:Lin ES-1 845 August 31, 2010 Page 7 Foundations In our opinion, the proposed single-family residence can be supported on conventional shallow foundations supported on competent or recompacted native soil or structural fill. We anticipate competent native soil capable of providing adequate foundation support will be encountered at foundation elevations for the daylight basement or at depths of between two to four feet below existing grade. Loose or otherwise unsuitable soil should be removed and replaced with structural fill. Assuming the foundations will be supported as described above, the following parameters can be used for the foundation design: * Allowable soil bearing capacity 2,500 psf & Coefficient of friction 0.40 (Foundation /soil interface) 0 Passi ve resistance 350 pcf (structural backfill) 0 Wind and seismic allowable one-third Increase * Total settlement approximately 1.0 inches 0 Differential settlement approximately 0.5 to 0.75 inches A factor -of -safety of 1.5 had been included in the friction and passive resistance values. Seismic Considerations The 2006 International Building Code specifies several soil profiles that are used as a basis for seismic design of structures. Based on the soil conditions observed at the test pit locations, Site Class C, from table 1613.5.2, should be used for design. In our opinion, liquefaction susceptibility at the site can be characterized as low. The relative density of the native soil and lack of a shallow groundwater table is the primary basis for this opinion. Slab -On -Grade Floors Slab -on -grade floors should be supported on a minimum of one foot of structural fill. A capillary break consisting of a minimum of four inches of free draining crushed rock or gravel should be placed below the slab. The free draining material should have a fines content of 5 percent or less (percent passing the #200 sieve, based on the minus three-quarter inch fraction). Installation of an approved vapor barrier should be installed below the slab. The vapor barrier must be a product specifically designed for that purpose and installed in accordance with.the manufacturer's specifications. Cast -In -Place Retaininq Walls Retaining walls should be designed to resist earth pressures and any applicable surcharge loads. For design, the following parameters can be assumed for retaining wall design: Earth Solutions NW, LLC I I I I I I I I I I I I I I I Thomas Reilly & Sharon Lin ES-1845 Page 8 August 31, 2010 • Active earth pressure (yielding wall) • At -rest earth pressure (restrained wall) • Passive resistance • Coefficient of friction 35 pcf (equivalent fluid) 50 pcf 350 pcf (equivalent fluid) 0.40 Additional surcharge loading from foundations, sloped backfill, or other loading should be included in the retaining wall design. Drainage should be provided behind retaining walls such that hydrostatic pressures do not develop. If drainage is not provided, hydrostatic pressures should be included in the wall design. ESNW should review retaining wall designs to confirm the recommended earth pressure values have been incorporated into design and to provide additional recommendations, as necessary. Retaining walls should be backfilled with free draining material that extends along the height of the wall, and a distance of at least 18 inches behind the wall. The upper one foot of the wall backfill can consist of a less permeable soil, if desired. A rigid, perforated drain pipe should be placed along the base of the wall, and connected to an approved discharge location. A typical retaining wall and drainage detail is illustrated on Plate 4 of this report. Drainage The presence of groundwater seepage should be expected in the building site excavations and the utility trench excavations. Temporary measures to control groundwater and surface water runoff during construction will likely involve the use of interceptor trenches, sumps and associated conveyance systems. Interceptor trenches should be installed along the cut slope areas as necessary during the mass grading of the site. A representative of ESNW should observe site conditions during the grading and utility installation and provide supplement recommendations for drainage, if necessary. Water must not be allowed to flow over the top of the adjacent slopes. Provisions should be included in site designs to either tightline drainage elements to the base of the slope or convey runoff to an approved discharge point away from the slope area. In our opinion, perimeter footing drains should be installed at or below the invert of the building footings. A typical footing drain detail is provided on Plate 5 of this report. LIMITATIONS The recommendations and conclusions provided in this geotechnical engineering study are professional opinions consistent with the level of care and skill that is typical of other members in the profession currently practicing under similar conditions in this area. A warranty is not expressed or implied. Variations in the soil and groundwater conditions observed at the test pit and test pit locations may exist, and may not become evident until construction. ESNW should reevaluate the conclusions in this geotechnical engineering study if variations are encountered. I Earth Solutions NW, LLG Thorhas Reilly & Sharon Lin ES-1845 August 31, 2010 Page 9 Additional Services ESNW should have an opportunity to review the final design with respect to the geotechnical recommendations provided in this study. ESNW should also be retained to provide testing and consultation services during construction.
