1 Introduction The purpose of this report is to describe subsurface conditions, present geotechnical analysis results, and provide recommendations for earthwork activities at the US Golden Eagle Farms, Ltd. (USGEF) Site. The Site is a blueberry farm located east of Larimer Road in the Marshland Flood Control District just south of Everett in Snohomish County, Washington (Figure 1). The Site comprises 50 acres over two tax lots: 28050800101700 and 28050900200900. The owners of the neighboring property to the south (i.e., Daniel and Shavonne Tonnes) entered a lawsuit against USGEF regarding earthwork activity that had impacted their property, citing violations of the Clean Water Act Sections 401 and 404 and City of Everett Municipal Code 19.37.250(B) and 19.37.260. A settlement agreement was reached mandating USGEF to perform required earthwork to correct any damages caused to the Tonnes property, including but not limited to the filling, relocating, and extending of existing flow ditches on the property. This report was prepared to meet the requirements of Study 3 as specified in the Tonnes v. Golden Eagle Farms Settlement Agreement.

This memorandum includes the following:

• Subsurface conditions observed from soil boring explorations• Discussion and interpretation of laboratory results• Geotechnical engineering recommendations for restoration earthwork• Recommendations for materials handling, safety, and water management during construction

2 Subsurface Conditions

2.1 Subsurface Investigation Subsurface geotechnical conditions at the Site were investigated by Anchor QEA on January 30 and 31, 2020. The exploration and testing program included the following:

• Advance six hand auger borings (designated HA-1 through HA-6) at selected locations,conduct visual classification of observed soils in each boring, and collect representative soilsamples for laboratory testing.

• Conduct four dynamic cone penetrometer (DCP) tests (designated DCP-1 through DCP-4) atselected locations.

Three of the six hand augers and all four DCP tests were conducted by Anchor QEA along the top of the east slope of Ditch 3 where fill material is to be placed as part of the restoration earthwork. The other three hand augers were conducted along the proposed excavation to extend the Unnamed Tributary (UNT). The locations of the hand auger borings and DCP tests are displayed in Figure 2. The hand auger exploration logs are provided in Appendix A, and the DCP results are in Appendix B.

The borings were advanced by hand using a 3¼-inch-diameter auger. Boring depths ranged from 3 to 9.4 feet below ground surface. The termination depth for each boring was based on practical refusal of the auger. Samples were collected from each of the borings for laboratory testing. Exploratory borings were used to provide an understanding of subsurface conditions, as well as to provide samples for laboratory testing.

DCP tests were conducted using a hand-operated, multi-flight steel probe with a sacrificial steel conical tip, and a 35-pound hammer weight. The weight was manually raised to 15 inches and then dropped (allowed to free fall), transferring energy through the lower flights to the cone tip. Advancement of the probe was recorded in 10-centimeter increments until practical refusal was met or the maximum depth of the available steel flights was reached (5 meters). All four DCP tests were driven to a cone tip depth of 500 centimeters (5 meters, 16.4 feet).

2.2 Laboratory Testing Soil samples from five of the six borings (HA-1 and HA-3 to HA-6) were submitted for geotechnical analysis to an independent geotechnical laboratory, Materials Testing and Consulting, Inc. A total of 10 samples were collected and submitted to the testing laboratory.

Samples were analyzed for the following parameters:

• Moisture content (ASTM D2216)• Atterberg limits (ASTM D4318)• Particle size (ASTM D422)

Geotechnical Investigation and Recommendations 3 March 2020

• Specific gravity (ASTM D854)• Modified Proctor (ASTM D1557)

General testing procedures and testing results as generated by the laboratory are provided in Appendix C.

2.3 Subsurface Soil Profile The following is a description of the generalized subsurface soil profile that was observed, with a discussion of the key characteristics of the major soil units encountered during the investigation, listed in order from the ground surface downward. Table 1 provides a summary of the depths of each unit encountered in each hand driven auger.

Sandy Silt (ML). The surficial layer of soil in borings HA-1 through HA-2 along the north end of the proposed UNT extension was brown to gray sandy silt ranging in thickness from 2.2 to 2.6 feet below ground surface. At the surface, the silt was typically medium stiff and dry to damp with occasional organic material, and graded to wet and stiff at the bottom of the layer. This unit was found to be non-plastic.

Silty Sand (SM). Silty sand was encountered in all borings. This layer was found at the surface of borings HA-3 through HA-6, ranging in thickness from 2.2 to 6.2 feet below ground surface, and underlaying silt in borings HA-1 and HA-2. At the surface, this layer of silty sand was typically loose, dry to damp, and brown with occasional red mottling. Beneath the silt layers found in HA-1 and HA-2, this material was typically loose and dry to damp, grading to wet and medium dense at the bottom of the layer. At boring HA-6, the silty sand graded to bluish gray at 1.3 feet below ground surface.

Poorly Graded Sand with Silt (SP-SM). A layer of poorly graded sand with silt was discovered underlaying the surficial silty sand in boring HA-6. This layer, 2.2 to 5.8 feet thick below ground surface, was moist to wet, gray-white, and loose in density.

2.4 Groundwater During the advancement of hand driven augers, the approximate depth that water was encountered was measured within each boring. Groundwater was observed at depths of 1.9 to 4.4 feet below ground surface. The variations in depth are likely due to the variations in depths of each soil unit. Groundwater depth was estimated using an engineer’s tape measure. Water levels were measured as encountered at the time of exploration and may not be accurate representations of long-term groundwater levels because seasonal variation is expected.

3 Geotechnical Engineering Evaluations Geotechnical evaluations were conducted to assess the stability of earthen fill that will be placed for the restoration project. This section describes slope stability evaluations that were completed in support of the work.

Slope stability was modeled with Rocscience Slide 2018 software Version 8.031 (Rocscience 2018) using limit equilibrium methods of analysis. The soil model for limit equilibrium analysis is a rigid, perfectly plastic soil model. The assumptions inherent to this model are that the anticipated sliding mass remains rigid (i.e., non-deformable) and the soil strength along the slip plane is fully mobilized at failure. Although this analysis method does not directly represent the true behavior of the soil during a slope failure, it is intended to provide a reasonable indication of the overall stability of a slope and is the standard of practice for these types of engineering evaluations.

The stability of the future fill slope along cross section G to G’, in the southern portion of the Site, was evaluated (Figure 2). To perform the analysis, a geologic cross section was developed using the existing topographic survey data, available groundwater data, GPS data collected at the time of the exploration, and subsurface stratigraphy obtained as part of the investigations. The location of the geologic cross section was selected based on the areas with the highest slope and thickest proposed fill within an existing drainage ditch. Slope angles that are stable for section G-G’ are expected to be stable for other fill locations because those areas will have less fill and lower slope heights.

The model requires input of a geologic profile, assignment of strength parameters to the various soil layers, selection of the type of “slip surface” to be modeled (i.e., circular or non-circular), and methods for evaluating limit equilibrium forces and moments.

Table 2 summarizes the modeling index and strength parameters used for each soil material for the short-term (undrained) stability and long-term (drained) stability. Modeling parameters were established using geotechnical laboratory test results, as well as correlations to measured DCP values to standard penetration test blow counts. The index parameter correlations used are as presented in geotechnical engineering design guidance and based on experience with similar materials on other projects.

3.1 Calculation of Factors of Safety For this model, both the Spencer (1967) and GLE Morgenstern and Price (1965) methods were used to compute the Factor of Safety (FOS). These methods satisfy both force and moment equilibrium for the slip surface being evaluated. The limit equilibrium method calculates the FOS by comparing the “driving” forces for an assumed failure wedge with the “resisting” forces provided by the shear strength of the soils along the assumed failure surface. The typical recommended target factor of safety for engineered slopes is 1.3 for short-term conditions, 1.5 for long‑term conditions, and 1.1 for “rapid drawdown”1 conditions based on U.S. Army Corps of Engineers guidance (USACE 2003).

The stability of the slope along the selected cross section was evaluated assuming a high-water table within the repositioned Ditch 3 at the toe of the backfill slope. Varying degrees of slope steepness were assessed to determine the FOS associated with each.

3.2 Discussion of Stability Results The results of the modeling indicate that the proposed backfill slope meets the recommended FOS for an engineered slope when constructed to a slope of 4 horizontal to 1 vertical (4H:1V) or flatter. Table 3 summarizes the results for each slope analyzed. Figures 3, 4, and 5 display the undrained (short-term), drained (long-term), and rapid drawdown conditions of the recommended backfill scenario of 4H:1V, respectively.

1 The term “rapid drawdown” typically refers to the operation of impoundments and dams, where reservoir levels can drop quickly, affecting slope stability. In the context of our evaluation for this project, the rapid drawdown evaluation simulates the behavior of the compacted fill material as the water level returns to normal following a future flood at the project site.

4 Construction Recommendations

4.1 Native Backfill Material Properties Based on the Proctor sample collected during the January 2020 geotechnical investigation by Anchor QEA at the location of HA-3, it is recommended that on-site materials should be compacted to at least 90% of the maximum dry density (as measured by the Modified Proctor test) when being used as fill. The maximum dry density of this material was found to be 116.4 pounds per cubic foot (pcf) and the optimum moisture content to be 10.0%. The Proctor results for the fill material described above are provided in Appendix C.

4.2 Earthwork Specifications The following section will describe specifications for site preparations as well as field and laboratory testing of relative density and percent moisture of material used as fill.

Site Preparation Following the stripping and grubbing of all surficial organics, as well as 2 to 3 inches of topsoil, the native backfill material shall be placed in no more than 12- to 18-inch-thick loose lifts and compacted using a vibratory rolling compactor. The contractor shall provide density and moisture content data to the engineer of record during construction to ensure adequate compaction of the fill material was achieved.

If the native sand material from the extension of the UNT ditch is not sufficient to fill Ditch 3, material will be imported to achieve volume requirements. Imported material should conform to Section 9.03-14(3) (Common Borrow) of the Washington State Department of Transportation Standard Specifications. Material shall be free of wood and organic waste or any other extraneous material. Imported material should be compacted to the same standard as on-site native material.

The number of field tests as recommended in DM-7.02 Foundations and Earth Pressures (NAVFAC 1986) for material placed as part of an embankment is one test for every 500 cubic yards. Additionally, supplemental testing should be conducted whenever there is a suspicion of a change in the material type, quality of moisture control, or effectiveness of compaction.

Moisture Control Because of the nature of the native material, the moisture content of the soil at the time of placement may be sensitive to oversaturation. If construction under relatively dry conditions is not possible, then moisture conditioning of the soil may be required to achieve adequate compaction. Moisture conditioning may involve the blending of materials from wet and dry sections of the

Geotechnical Investigation and Recommendations 9 March 2020

borrow area (near HA-3), and/or the use of alternative compaction equipment may be necessary, such as a sheep’s foot roller.

4.3 Excavation Safety All Occupational Safety and Health Administration (OSHA) guidelines (OSHA 2019), and Washington Department of Labor and Industries requirements (Chapter 296-155 Washington Administrative Code), should be followed during excavation operations. Typically, measures for safe excavation would include the following:

• Keep heavy equipment and surcharge loads from excavation edges and at top of slope.• Limit cut depths to 4 feet or less where possible.• For excavations deeper than 4 feet, use benching and/or stable excavation side slopes, or

where side slopes are not possible, temporary shoring.

Excavation safety should be the responsibility of the contractor because they are the party continuously present and in control of means and methods, and therefore they have the most control and influence on safe excavation practices.

4.4 Water Management Based on the presence of waterways in the work area, observed seeps along the base of the ridgeline, oversaturated zones at depth, and a varying water table depth, it is likely that water will be encountered during construction. We recommend that the contractor perform a site visit prior to commencing work and make their own determination about the volume of water that they may need to manage during construction, and methods they may need to apply.

Temporary water management should be designed and implemented by the contractor as needed. If needed, it should have at least the following two key elements:

• Temporary rerouting of existing drainage ditches• Pumping from the excavation during construction

Appendix D Limitations Document

Geotechnical Investigation and Recommendations D-1 March 2020

Important Information About Your Geotechnical/Environmental Report

Consulting Services Are Performed for Specific Purposes and for Specific Clients Consultants prepare reports to meet the specific needs of specific individuals. A report prepared for a civil engineer may not be adequate for a construction contractor or even another civil engineer. Unless indicated otherwise, your consultant prepared your report expressly for you and expressly for the purposes you indicated. No one other than you should apply this report for its intended purpose without first conferring with the consultant. No party should apply this report for any purpose other than that originally contemplated without first conferring with the consultant.

The Consultant's Report Is Based on Project-Specific Factors A geotechnical/environmental report is based on an investigation plan designed to consider a unique set of project-specific factors. Depending on the project, these may include: the general nature of the structure and property involved; its size and configuration; its historical use and practice; the location of the structure on the site and its orientation; other improvements such as access roads, parking lots, and underground utilities; and the additional risk created by scope-of-service limitations imposed by the client. To help avoid costly problems, ask the consultant to evaluate how any factors that change subsequent to the date of the report may affect the recommendations. Unless your consultant indicates otherwise, your report should not be used: 1) when the nature of the proposed project is changed (for example, if an office building will be erected instead of a parking garage, or if a refrigerated warehouse will be built instead of an unrefrigerated one, or chemicals are discovered on or near the site); 2) when the size, elevation, or configuration of the proposed project is altered; 3) when the location or orientation of the proposed project is modified; 4) when there is a change of ownership; or 5) for application to an adjacent site. Consultants cannot accept responsibility for problems that may occur if they are not consulted after factors which were considered in the development of the report have changed.

Subsurface Conditions Can Change Subsurface conditions may be affected as a result of natural processes or human activity. Because a geotechnical/environmental report is based on conditions that existed at the time of subsurface exploration, construction decisions should not be based on a report whose adequacy may have been affected by time. Ask the consultant to advise if additional tests are desirable before construction starts; for example, groundwater conditions commonly vary seasonally.

Geotechnical Investigation and Recommendations D-2 March 2020

Construction operations at or adjacent to the site and natural events such as floods, earthquakes, or groundwater fluctuations may also affect subsurface conditions and, thus, the continuing adequacy of a geotechnical/environmental report. The consultant should be kept apprised of any such events, and should be consulted to determine if additional tests are necessary.

Most Recommendations Are Professional Judgments Site exploration and testing identifies actual surface and subsurface conditions only at those points where samples are taken. The data were extrapolated by your consultant, who then applied judgment to render an opinion about overall subsurface conditions. The actual interface between materials may be far more gradual or abrupt than your report indicates. Actual conditions in areas not sampled may differ from those predicted in your report. While nothing can be done to prevent such situations, you and your consultant can work together to help reduce their impacts. Retaining your consultant to observe subsurface construction operations can be particularly beneficial in this respect.

A Report's Conclusions Are Preliminary The conclusions contained in your consultant's report are preliminary because they must be based on the assumption that conditions revealed through selective exploratory sampling are indicative of actual conditions throughout a site. Actual subsurface conditions can be discerned only during earthwork; therefore, you should retain your consultant to observe actual conditions and to provide conclusions. Only the consultant who prepared the report is fully familiar with the background information needed to determine whether or not the report's recommendations based on those conclusions are valid and whether or not the contractor is abiding by applicable recommendations. The consultant who developed your report cannot assume responsibility or liability for the adequacy of the report's recommendations if another party is retained to observe construction.

The Consultant's Report Is Subject to Misinterpretation Costly problems can occur when other design professionals develop their plans based on misinterpretation of a geotechnical/environmental report. To help avoid these problems, the consultant should be retained to work with other project design professionals to explain relevant geotechnical, geological, hydrogeological, and environmental findings, and to review the adequacy of their plans and specifications relative to these issues.

Boring Logs And/or Monitoring Well Data Should Not Be Separated from the Report Final boring logs developed by the consultant are based upon interpretation of field logs (assembled by site personnel), field test results, and laboratory and/or office evaluation of field samples and data. Only final boring logs and data are customarily included in geotechnical/environmental reports.

Geotechnical Investigation and Recommendations D-3 March 2020

These final logs should not, under any circumstances, be redrawn for inclusion in architectural or other design drawings, because drafters may commit errors or omissions in the transfer process.

To reduce the likelihood of boring log or monitoring well misinterpretation, contractors should be given ready access to the complete geotechnical engineering/environmental report prepared or authorized for their use. If access is provided only to the report prepared for you, you should advise contractors of the report's limitations, assuming that a contractor was not one of the specific persons for whom the report was prepared, and that developing construction cost estimates was not one of the specific purposes for which it was prepared. While a contractor may gain important knowledge from a report prepared for another party, the contractor should discuss the report with your consultant and perform the additional or alternative work believed necessary to obtain the data specifically appropriate for construction cost estimating purposes. Some clients hold the mistaken impression that simply disclaiming responsibility for the accuracy of subsurface information always insulates them from attendant liability. Providing the best available information to contractors helps prevent costly construction problems and the adversarial attitudes that aggravate them to a disproportionate scale.

Read Responsibility Clauses Closely Because geotechnical/environmental engineering is based extensively on judgment and opinion, it is far less exact than other design disciplines. This situation has resulted in wholly unwarranted claims being lodged against consultants. To help prevent this problem, consultants have developed a number of clauses for use in their contracts, reports and other documents. These responsibility clauses are not exculpatory clauses designed to transfer the consultant's liabilities to other parties; rather, they are definitive clauses that identify where the consultant's responsibilities begin and end. Their use helps all parties involved recognize their individual responsibilities and take appropriate action. Some of these definitive clauses are likely to appear in your report, and you are encouraged to read them closely. Your consultant will be pleased to give full and frank answers to your questions.
