The purpose of this study was to complete subsurface explorations within the project area to characterize soil and groundwater conditions and to develop geotechnical conclusions and recommendations to support design and construction of the proposed improvements. The general project location is shown on the Vicinity Map (Figure 1). The Site and Exploration Plan (Figure 2) shows some of the existing surrounding features and the approximate locations of the explorations completed for this study. Appendix A presents a description of the field exploration program, summary logs of conditions observed in the explorations completed for this study, and a description and results of the laboratory testing program. This report has been prepared based on our discussions with Brian Reeves of Baysinger Partners Architecture PC (Baysinger); base maps of the project area provided by Baysinger; our review of readily available subsurface information in the project area; results of explorations completed for this project; our familiarity with geologic conditions within the vicinity of the project area; and our experience on similar projects. 1.1 PROJECT DESCRIPTION Based on information provided by Baysinger, we understand that the existing building located at 1800 South 320th Street will be demolished and replaced with a new commercial building. The new building will be a 10,000 square foot (sf), single-story structure with a slab-on-grade floor. Foundation support will be provided by spread footings. New asphalt paving is planned for the area immediately surrounding the building. Porous pavement is planned for an area of about 4,500 sf to the west of the new building. 1.2 SCOPE OF SERVICES Landau Associates was contracted by Harsch Investment Properties (Harsch) to provide geotechnical services to support the project. Our geotechnical services were provided in accordance with the scope of services and outlined in our Proposal for Geotechnical Services dated February 20, 2014 and our professional services agreement with Harsch dated March 10,2014. 3/19/14 Y:\836\002.01O\R\Ulta Beauty_final rpt.docx LANDAU ASSOCIATES 1-1 • • To support the proposed project,we provided the following specific services: • Compiled and reviewed readily available geotechnical and geologic information in the project vicinity • Completed three geotechnical soil borings (B-1 through B-3) to depths of between about 8 and 11'1/2 feet (ft) below the ground surface (BGS) to characterize soil and groundwater conditions • Logged each soil unit observed in the explorations and recorded pertinent information, including soil sample depths, stratigraphy, soil engineering characteristics, and groundwater occurrence • Completed geotechnical laboratory testing consisting of natural moisture content determinations and grain size analyses on selected samples from the explorations • Completed geotechnical engineering analyses and developed geotechnical engineering conclusions and recommendations for design and construction of the proposed improvements • Prepared and submitted this written report summarizing our findings, conclusions, and recommendations for the project.

Interpretations of the site conditions are based on the results of our review of available information, site reconnaissance, subsurface explorations, and laboratory testing. 2.1 SURFACE CONDITIONS The project area forms an approximate rectangle of about 250 ft (east-west) by 200 ft (north- south) and is bordered by South 320th Street to the south and an asphalt paved parking lot on all other sides. The site generally slopes gently down to the south at an average 2Y2 percent grade. The proposed building will be located near the location of the existing building, Billy McHale's Restaurant, and will have a similar footprint; shifted about 15 ft to the south. The building footprint is rectangular;measuring about 125 ft(east-west)by 80 ft(north-south). The surrounding property is commercial with pavement covering the majority of the ground surface around the existing building. Vegetation is limited to landscaping shrubs and small trees planted in islands dispersed throughout the adjacent parking lot and along South 320th Street. 2.2 GEOLOGIC SETTING Geologic information for the project area was obtained from the Geologic Map of the Poverty Bay 7.5'Quadrangle, King and Pierce Counties, Washington (Booth et al. 2004). Near surface deposits in the project area are mapped as glacial till. Soil defined as glacial till consists of a dense to very dense, unsorted mixture of boulders, cobbles, gravel, and sand in a matrix of silt and clay with some lenses of sorted, stratified sand and gravel. This unit typically exhibits low permeability and high shear strength, characteristics resulting from compaction by the weight of the overlying glacier. The observed geology is generally consistent with the mapped geology,with up to a few feet of artificial fill placed over the glacial till. 2.3 SUBSURFACE CONDITIONS Subsurface soil and groundwater conditions within the limits of the project area were explored on February 27,2014. The exploration program consisted of advancing three hollow-stem auger borings(B- 1 through B-3). The approximate locations of the borings are shown on the Site and Exploration Plan (Figure 2). Borings were advanced to depths ranging from about 8 to 11'/2 ft BGS using a truck-mounted drill rig operated by Holocene Drilling, Inc. of Puyallup, Washington under subcontract to Landau 3/19/14 Y:\836\002.010\R\Ulta Beauty_final cpt.docx LANDAU ASSOCIATES 2-1 1 ' Associates. The explorations were located approximately in the field by hand-taping from existing physical features referenced on a site plan provided by Baysinger. A detailed discussion of the field exploration program, edited logs of the borings, laboratory test results, and discussions of test procedures used are presented in Appendix A. Based on results of the field exploration program, the project area is interpreted to be underlain by artificial fill over glacial till. At the boring locations, fill extends to depths ranging from about 1'/2 to 5'h ft BGS. Glacial till was encountered below the fill to the depths explored in each boring. A cobble was encountered at about 2'/2 ft BGS in boring B-1. Cobbles and boulders are common in glacial till deposits, and are also present in the fill material. Construction activities should anticipate the presence of cobbles and boulders throughout the site. Boring B-1 was advanced on the west side of the building where porous pavement is proposed. Below about 2 inches of ACP and 4 inches of base course, fill was encountered to about 5'V2 ft BGS. Fill was observed to consist of medium dense to dense, gravelly sand with silt with occasional zones of silty sand with gravel. Glacial till was encountered below the fill to the depth explored (about 11'/2 ft BGS). Glacial till was observed to consist of very dense,gravelly,very silty sand. Borings B-2 and B-3 were advanced on the north and east sides of the proposed building, respectively. ACP thickness at these locations ranged from about 1'h to 2'/2 inches, with the underlying base course thickness ranging from about 2 to 3 inches. In both borings, fill was encountered below the base course to about P/2 ft BGS. Fill was observed to consist of medium dense to dense, sandy gravel with silt. Glacial till was encountered below the fill to the depths explored(about 8 to 9 ft BGS). Glacial till was observed to consist of very dense soil ranging from silty,very sandy gravel to silty,gravelly sand. 2.4 GROUNDWATER At the time of exploration (February 27, 2014), groundwater was not encountered in any of the explorations advanced for this study. Thin, perched water layers were observed on top of the glacial till in all borings and near the top of the fill in boring B-1. Mottling was observed in the glacial till in borings B-1 and B-2, indicating the seasonal or periodic presence of groundwater. It should be noted that the groundwater conditions reported on the summary logs are for the specific locations and dates indicated, and therefore, may not necessarily be indicative of other locations and/or times. Furthermore, it is anticipated that groundwater conditions will vary depending on local subsurface conditions, the weather, and other factors. 3/19/14 Y:\836\002.010\]t\UltaBeauty_final rpt.cbcx LANDAU ASSOCIATES 2-2 ' • • 3.0 CONCLUSIONS AND RECOMMENDATIONS Based on conditions observed in the explorations and results of our engineering evaluation, construction of the proposed Ulta Beauty building is considered to be feasible using conventional means and methods. Geotechnical conclusions and recommendations are presented in the following sections for earthwork,foundation design,and pavement sections. 3.1 EARTHWORK Earthwork to accommodate the proposed improvements for the project is expected to consist of site preparation,site grading,subgrade preparation,and fill placement and compaction. 3.1.1 WET WEATHER CONSIDERATIONS Earthwork-related construction will be influenced by weather conditions. Much of the near- surface soils contain an appreciable amount of fine sand and silt and are anticipated to be moderately to highly moisture sensitive. When at all feasible, earthwork activities should be completed during the relatively warmer and drier period between about mid-summer to early fall. Completing these activities outside of this normal construction window could lead to an increase in construction costs due to weather- related delays,repair of disturbed areas,and the increased use of"all-weather"import fill materials. 3.1.2 SITE PREPARATION Topsoil, or other organic rich soil, was not encountered in any of the explorations completed for our study but may be present in localized areas. If encountered, topsoil, and/or other organic-rich soil, should be stripped to expose the underlying inorganic soil. Stripped material is not considered suitable for use as structural fill. Stripped material should either be wasted off site at an approved location or stockpiled for later use as topsoil. Existing improvements (e.g., existing pavement and foundations) should be removed and disposed of at an approved offsite location. All incidental excavations associated with removal of existing improvements should be backfilled in accordance with the recommendations presented in Sections 3.1.5 and 3.1.6 of this report. Any utilities that will be abandoned that are less than 3 ft deep should be removed and disposed of at an approved offsite location. Deeper abandoned pipelines left in place should be grouted full with controlled density fill with a minimum unconfined compressive strength of at least 300 pounds per square inch. 3/19/14 Y:\836\002.010\R\UltaBeauty_finalrpt.docx LANDAU ASSOCIATES 3-1 • • 3.1.3 TEMPORARY AND PERMANENT SLOPES In order to accommodate the construction of the proposed improvements,temporary excavations may be required. Based on the soil conditions observed in our explorations,we anticipate that temporary excavations will generally encounter medium dense to dense fill and/or very dense glacial till. Temporary excavations in fill should be sloped no steeper than 11/2H:1 V (horizontal to vertical). Temporary excavations in glacial till should be sloped no steeper than 1 H:1 V. Temporary excavation slopes should be protected by covering with plastic sheeting or other approved means to prevent erosion. Temporary excavation slopes should be the sole responsibility of the contractor. All local, state, and federal safety codes should be followed. The contractor should implement measures to prevent surface water runoff from entering excavations. All temporary excavation slopes should be monitored by the contractor during construction for any evidence of instability. If instability is detected, the contractor should flatten the temporary excavation slopes or install temporary shoring. If groundwater or groundwater seepage is present,flatter excavation slopes should be expected. All permanent cut and fill slopes should be sloped no steeper than 2H:1 V. Permanent slopes should be hydroseeded as soon as practical to prevent erosion or covered with either mulch or erosion control netting/blankets, and bonded fiber matrix. 3.1.4 SUBGRADE PREPARATION Following site preparation and any required overexcavation to remove unsuitable material, and before placement of any structural fill, the upper 9 to 12 inches of exposed soil should be scarified, moisture-conditioned, and compacted as described in Section 3.1.6 of this report. Where undisturbed glacial till is present, this scarification process is not necessary. The prepared subgrade should be proof- rolled with a loaded dump truck, large self-propelled vibrating roller, or equivalent piece of equipment in the presence of a qualified geotechnical or civil engineer to check for the presence of soft, loose, and/or disturbed areas. If any soft, loose, and/or disturbed areas are revealed during proof-rolling, these areas should either be moisture-conditioned and recompacted to the required density, or removed and replaced with import structural fill compacted to the required density. 3.1.5 STRUCTURAL FILL The suitability of excavated soil or imported soil for use as structural fill will depend on the gradation and moisture content of the soil when it is placed. As the amount of fines increases, the soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to achieve. Soil containing more than about 5 percent fines cannot consistently be compacted to a dense, non-yielding condition when the water content is greater than about 2 to 3 percent 3/19/14 Y:\836\002.010\R\Ulta Beauty_6na1 rpt.docx LANDAU ASSOCIATES 3-2 • • above optimum moisture content. Optimum moisture content is the moisture content at which the greatest compacted dry density can be achieved. The soil at the site is expected to consist primarily of sand with variable gravel and silt contents. Provided the silt content remains below about 5 to 10 percent, these soil types generally make adequate borrow material and trench backfill if oversize particles (greater than 4 to 6 inches) are removed. These soil types generally exhibit moderate moisture sensitivity and can generally be successfully worked throughout most of the year. Based on the results of the field and laboratory testing program,most onsite soil will have greater than 10 percent fines, will be moisture sensitive,and is not recommended for use as structural fill. Fill is generally wet of the optimum moisture content for compaction, indicating that moisture-conditioning (i.e., drying) will be required to achieve the required compaction levels. Glacial till is generally near the optimum moisture content for compaction, but due to the high fines content and moisture sensitivity, we do not recommend glacial till for use as structural fill. With moisture sensitive soil, earthwork should be avoided during periods of extended precipitation. If the onsite soil is used for structural fill, the contractor will need to properly segregate the non-suitable material from the suitable material. Non-suitable material includes all soil too wet or dry to meet compaction requirements and soil with organics that will likely be encountered near existing planter areas. Furthermore, we recommend that full-time construction monitoring be provided in order to ensure that the contractor is properly segregating suitable from non-suitable material. If the onsite soil cannot be properly prepared to achieve the required compaction,or if the amount of site soil is insufficient to establish site grades, import fill will be required. For dry, warm weather conditions(late June through early October), import fill should consist of a well-graded sand, or sand and gravel, free of organics and other deleterious materials, with a maximum particle size not exceeding 4 inches. The material should contain less than 15 percent fines(material finer than the U.S.No. 200 sieve) and be maintained at a moisture content near optimum. If wet weather construction is anticipated, the amount of fines should not exceed 5 percent,based on the minus 3/4-inch fraction. 3.1.6 BACKFILL ANI)COMPACTION REQUIREMENTS In improved areas, such as beneath foundations, floor slabs, and pavements, structural fill should be placed in relatively uniform horizontal lifts, not exceeding 8 to 10 inches thick, loose measure. Each lift should be compacted to at least 95 percent of the maximum dry density as determined by the ASTM International (ASTM) D 1557 test procedure. In unimproved areas, such as landscape areas, fill should be placed in relatively uniform horizontal lifts of 12 to 18 inches thick, loose measure, and compacted to between 85 and 90 percent of the maximum dry density(ASTM D 1557). 3/19/14 Y:\836\002.010\2\Ulta Beauty_final rpt.docx LANDAU ASSOCIATES 3-3 i 3.2 FOUNDATION DESIGN RECOMMENDATIONS Recommendations for foundation support of the proposed improvements are summarized in this section of the report. 3.2.1 SEISMIC DESIGN CRITERIA The Pacific Northwest is seismically active, and the site could be subject to ground shaking from a moderate to major earthquake during the design life of the improvements. Consequently, moderate levels of earthquake shaking should be anticipated during the design of the project, and the proposed structures should be designed to resist earthquake loading using the appropriate design methodology. We understand that design of structural elements to accommodate seismic forces will be in accordance with the 2012 International Building Code (IBC; ICC 2012), which references American Society of Civil Engineers (ASCE) 7-10 (ASCE 2010). The site is underlain by medium dense to dense fill and very dense glacial till. Per Table 20.3-1 of ASCE 7-10,the Site Class is C,very dense soil. The following spectral accelerations for a 1 percent probability of exceedance in 50 years (USGS 2014) should be used to determine the design response spectrum per Figure 11.4-1 of ASCE 7-10: Spectral Acceleration for short periods(Ss): 129.4%of gravity(1.294g) Spectral Acceleration for a 1-second period(Si): 49.6%of gravity(0.496g) Peak Horizontal Ground Acceleration(PGA): 50.6%of gravity(0.506g) A value of 1.00 should be used for site coefficient Fa, 1.30 for site coefficient, F,,, and 1.00 for FPGA. 3.2.2 FOUNDATION SUPPORT AND SETTLEMENT The subgrade for shallow foundations should be prepared in accordance with the recommendations contained in Section 3.1.4. of this report. All prepared foundation-bearing surfaces should be free of any loose soil and water. Prepared footing subgrades should be observed by a qualified geotechnical or civil engineer to check that suitable bearing soils are present. All continuous and isolated spread footings should have minimum widths of 18 inches and 24 inches, respectively, and should be founded a minimum of 12 inches below the lowest adjacent final grade for frost protection. Assuming the above foundation support criteria are satisfied, continuous or isolated spread footings for the proposed structures may be proportioned using a maximum net allowable soil bearing pressure of 3,500 pounds per square foot (psf). The allowable bearing pressure includes a factor of safety of at least 3 on the calculated ultimate bearing capacity. The term "Net Allowable 3/19/14 Y:\836\002.010\R\UltaBeauty_finalrp[.docx LANDAU ASSOCIATES 3-4 ! • . J' Bearing Pressure"refers to the pressure that can be imposed on the soil at foundation level resulting from the total of all dead plus live loads (including snow loads), exclusive of the weight of the footing or any backfill placed above the footing. The maximum allowable bearing pressure can be increased by one-third for short-term transient loadings,such as wind or earthquakes. Settlement of shallow foundations depends on the foundation size and bearing pressure, as well as the strength and compressibility characteristics of the underlying bearing soil. Assuming construction is accomplished as previously recommended, we estimate the total settlement of continuous or isolated spread footings will be on the order of 1 inch. Differential settlement between similarly loaded foundation elements may be assumed to be on the order of 1h inch. Differential settlements between adjacent heavily loaded and lightly loaded foundations or between footings underlain by different subgrade soils would be greater. It is estimated that most of the settlement will occur during construction as loads are applied.Post-construction settlements should be negligible. 3.2.3 SLAB-ON-GRADE FLOORS Assuming that the subgrade is prepared in accordance with Section 3.1.4 of this report,the floor of the proposed building may be constructed as a slab-on-grade. A minimum of 4 inches of clean, free- draining material, such as 3/4-inch minus washed gravel, should be placed beneath slab-on-grade floors to act as a capillary break. If moisture penetration is a concern, a condensation barrier could be placed beneath interior slab- on-grade floors to prevent condensation and wicking of moisture through the floor slab. A condensation barrier is not necessary beneath exterior slabs. The condensation barrier should consist of a reinforced, 10-mil membrane with tape-sealed joints. The condensation barrier should be inspected to verify that all openings have been properly sealed. To facilitate concrete curing, the American Concrete Institute typically recommends placing a compacted, 4-inch-thick layer of clean, 3/4-inch minus, clean, crushed rock material, over the moisture barrier. Care should be taken during construction to prevent water penetration into this layer. Trapped water beneath the slab may lead to problems with interior flooring materials. 3.2.4 BELOW-GRADE WALLS The lateral pressures that develop along the face walls are dependent on the amount the walls are allowed to rotate or yield. If the walls are unrestrained against rotating and yielding at least 0.001 H, where H is the height of the wall (including embedment); the walls should be designed assuming active conditions. If the walls are restrained against rotating and yielding; the walls should be designed assuming at-rest conditions. 3/19/14 Y:\836\002.010\R\Ulta Beauty_final rpt.docx LANDAU ASSOCIATES 3-5 a1 is The following table provides design parameters for below-grade walls. The design parameters assume the wall backfill has a moist unit weight of 130 pounds per cubic foot (pcf) and an effective friction angle of 36 degrees. The parameters also assume there is level backfill behind the walls and wall drainage is provided as recommended in Section 3.2.6 of this report. EARTH PRESSURE PARAMETERS FOR BELOW GRADE WALLS Parameter Coefficient Equivalent Fluid Value Weight(pcf) Active Earth Pressure Coefficient(ka) 0.26 34 Seismic Earth Pressure Coefficient(Kae Active Conditions) 0.42 55 At-Rest Earth Pressure Coefficient(ka) 0.41 54 Seismic Earth Pressure Coefficient(Kao At-Rest Conditions) 0.70 91 Design of any subsurface walls should include appropriate lateral earth pressures caused by any adjacent surcharge loads. For uniform surcharge pressures due to vehicular loading, a uniformly distributed horizontal load of 0.26 times the surcharge pressure should be added for yielding walls(active conditions). For walls unable to rotate or translate(at-rest conditions), a uniformly distributed horizontal load of 0.41 times the surcharge pressure should be utilized for design. At a minimum, we recommend including a vertical surcharge load of 250 psf to account for vehicular traffic. Where large surcharge loads, such as heavy trucks, a crane, or other construction equipment will be located within a distance equal to one-half of the wall height, the abutments should be designed to accommodate the additional lateral pressures resulting from these surcharge loads. For seismic design, the horizontal earth pressure should be calculated and distributed as a single triangular pressure utilizing the seismic earth pressure coefficients provided in the above table. The resultant of the horizontal earth pressure can be assumed to act a point of V3H above the base of the wall. The horizontal earth pressure for seismic design includes both static and dynamic lateral pressures and must not be added to the static lateral earth pressure. 3.2.5 RESISTANCE TO LATERAL LOADS Resistance to lateral loads may be assumed to be provided by friction acting on the base of footings, and by passive lateral earth pressures acting against the sides of footings. An ultimate coefficient of sliding resistance of 0.55, applied to the vertical dead loads only, may be used to compute frictional resistance. For design purposes, the passive resistance of undisturbed, glacial till or properly compacted structural fill placed against the sides of foundations may be considered equivalent to a fluid with a density of 250 pcf. The upper 1 ft of passive resistance should be neglected in design if not covered by pavement or floor slabs. The value for the coefficient of sliding resistance does not include a 3/19/14 Y:\836\002.010\R\UltaBeauty_finaltpt.docx LANDAU ASSOCIATES 3-6 factor of safety, and the value for the foundation passive earth pressure has been reduced by a factor of 2.0 to limit deflections to less than 1 percent of the embedded depth. 3.2.6 WALL BACKFILL AND FOUNDATION DRAINAGE CONSIDERATIONS To provide drainage behind retaining walls, backfill within 3 ft of the face of the wall should be free-draining,well-graded sand and gravel material with less than 5 percent fines and a maximum particle size less than 2 inches. Because of its potential to run,we do not recommend the use of pea gravel as wall backfill. Wall backfill should be placed in 6-inch lifts and be compacted to at least 95 percent of the maximum dry density(ASTM D 1557). To avoid overstressing the wall, wall backfill located within 3 ft of the wall face should be compacted with hand-operated equipment. We recommend providing foundation drainage for all below-grade walls and around all inhabitable structures. The foundation drainage system should consist of a minimum 4-inch diameter, heavy duty,perforated PVC pipe(with the perforations placed downward). The perforated pipe should be placed in a minimum 12-inch-thick envelope of 1-inch minus drain gravel. The drain gravel should completely surround the perforated drain pipe and be completely surrounded by a non-woven geotextile material such as Mirafi® 140N, Contech®C-40NW, or equivalent. The top of the perforated pipe should be no higher than the top of the adjacent footing. Foundation/wall drains should discharge into the site storm drainage system or an approved location. Roof downspouts should not be introduced into the footing drain,but discharged directly into the site stormwater system or other appropriate outlet by means of a tightline-type system. To reduce the possibility of water ponding and minimize infiltration adjacent to footings, the ground surface adjacent to structures should be sloped to promote surface water runoff away from the structure. 3.3 SITE UTILITIES The following sections provide geotechnical recommendations for design and construction of new site utilities. Geotechnical recommendations are included for installation of new site utilities including trench excavation and retention, pipe foundation support, pipe bedding and initial backfill, and trench backfill and compaction criteria. 3.3.1 TRENCH EXCAVATIONS AND SUPPORT It is anticipated that excavation for site utilities will generally be in medium dense to dense fill and very dense glacial till. A hydraulic excavator with sufficient reach should be able to excavate the proposed trenches to the depths planned. 3/19/14 Y:\836\002.010\Mita Beauty_final rpt.docx LANDAU ASSOCIATES 3-7 • Temporary excavations in excess of 4 ft should either be shored or sloped in accordance with Safety Standards for Construction Work Part N, Washington Administrative Code (WAC) 296-155-657. In the absence of groundwater seepage,fill soil is classified as a Type C soil and glacial till as Type B soil per WAC 296-155-657. If utility trench excavations are completed in the summer and early fall months, it is anticipated that the proposed utilities across most of the site may be installed without encountering significant groundwater within the trench depth. However, localized zones of perched groundwater may be encountered within the trench zone,particularly during winter and spring months. If shallow groundwater is encountered during trench excavation, we expect that open sump pumping will be adequate to control groundwater flow into the trench,provided the trench walls remain stable. Surcharge loads on trench support systems due to construction equipment, stockpiled material, and vehicle traffic should be included in the design of any anticipated shoring system. In addition, the contractor should implement measures to prevent surface water runoff from entering trenches and excavations. In addition, vibration as a result of construction activities and traffic may cause caving of the trench walls. All open cuts should be monitored during and after excavation for any evidence of instability. If instability is detected, the contractor should flatten the side slopes or install temporary shoring. If groundwater seepage is present, and the trench is not properly dewatered, the soil within the trench zone may be prone to caving, thereby, resulting in trench widths that may be substantially wider than a properly dewatered trench. 33.2 PIPE FOUNDATION,BEDDING,AND INITIAL BACKFILL The site soil will provide adequate foundation support for utilities provided the foundation soil remains in a relatively undisturbed condition and is properly dewatered. Soil exposed in the trench bottom can be easily disturbed, and in a disturbed condition will generally provide poor foundation support for the pipeline. If the bottom of the trench becomes disturbed due to excavation and/or foot traffic during pipe placement, the disturbed material should be overexcavated to expose undisturbed foundation soil. The overexcavation should be backfilled with suitable foundation material to provide a firm trench bottom. Foundation material should consist of a well-graded sand and gravel material free from roots,topsoil, lumps of silt and clay, and organic and inorganic debris with less than 5 percent fines and a maximum particle size less than 2 inches. Pipe zone bedding material should consist of crushed, processed, or naturally occurring granular material free of organic matter and other deleterious materials meeting the requirements in the table below. 3/19/14 Y:\836\002.010\R\UltaBeauty_fnal rpt.docx LANDAU ASSOCIATES 3-8 �► i PIPE ZONE BEDDING MATERIAL Percent Passing Sieve Size (by Dry Weight) 1'/2 inch 100 1 inch 75-100 5/8 inch 50-100 U.S.No.4 20-80 U.S.No.40 3-24 U.S.No.200 10 max Sand Equivalent 35 min Pipe bedding material should extend at least 6 inches below the invert of the pipe. The bedding material should be compacted to a relative density of at least 95 percent maximum dry density(ASTM D 1557). The initial backfill over the pipe should consist of bedding material and extend 6 inches above the crown of the pipe. The initial backfill should be brought up evenly around the pipe in relatively horizontal lifts not exceeding 6 inches, and worked under the haunches of the pipe by slicing with a shovel, vibration, or other approved procedures. In order to prevent damage to the pipe, the initial backfill directly over the pipe should only be compacted with hand-operated compaction equipment. 3.3.3 TRENCH BACKFILL The onsite granular soil may be used for trench backfill, provided it is properly moisture- conditioned in accordance with Section 3.1.5 of this report and compacted to the required density. If additional material is required for trench backfill, imported material meeting the requirements detailed in Section 3.1.5 of this report should be used for trench backfill. Trench backfill should be placed and compacted in accordance with Section 3.1.6 of this report. 3.4 PAVEMENTS This section contains a discussion of the feasibility of using porous pavement and recommendations for new asphalt concrete pavement sections assuming the subgrade is prepared in accordance with Section 3.1.4 of this report. 3.4.1 POROUS PAVEMENT DISCUSSION Soil below the existing ACP section in the vicinity of the proposed porous pavement section consists of about 4 inches of gravelly sand (base course) over fill consisting of medium dense to dense gravelly sand with silt and silty sand. Very low permeability glacial till underlies the fill at a depth of about 51 ft BGS. At the time of drilling,the base course in boring B-1 was wet; indicating the moist fill 3/19/14 Y:\836\002.010\RWltaBeauty_finalrpt.docx LANDAU ASSOCIATES 3-9 • • 1 . below it is poorly draining. A thin layer of wet soil was also observed immediately above theglacial till surface; indicating a very low permeability layer and barrier to subsurface water flow. Glacial till was encountered at about 11/2 ft BGS in boring B-2, about 100 ft east of the proposed porous pavement section. Based on results of our field exploration, existing soil below the proposed porous pavement section will have low to very low infiltration rates. Glacial till present at about 5'/2 ft BGS is effectively impermeable. Very little surface water is likely to infiltrate through the existing fill soil, and almost no water will infiltrate into the glacial till, which is shallow enough to govern infiltration across the site. Based on our experience,the highest infiltration rate probable in glacial till is about 0.05 inches per hour. If a porous pavement system is constructed, we recommend design and installation of an underdrain system to convey excess water to the public storm drain system. Design recommendations for the porous pavement section are provided in the following section. 3.4.2 POROUS PAVEMENT Porous pavement section recommendations assume that the pavement section is underlain by glacial till. The porous pavement section should consist of 3 inches of porous asphalt pavement,2 inches of choker course, and 4 inches of reservoir base course. These are minimum required thicknesses for structural support of the pavement. The thickness of the reservoir base course should be determined by a hydrologist,such that it is sufficiently thick to accommodate storage of groundwater until it has infiltrated into the native subgrade or the underdrain conveyance system. The subgrade for porous pavement should be graded level to allow for even distribution of infiltrating stormwater. The exposed subgrade should be proof-rolled by a fully loaded dump truck (or equivalent) in the presence of a qualified geotechnical or civil engineer to identify areas that are soft, loose, or disturbed. If soft, loose, or disturbed areas are observed,these areas should be overexcavated to firm bearing soil and replaced with reservoir base coarse material to obtain the design subgrade elevation. Reservoir base course material required to establish site grades should be compacted as discussed later in this report. To limit the amount of compaction of the pavement subgrade soil,construction traffic should be spread out evenly across the site. A non-woven geotextile meeting the following requirements should be placed on the prepared subgrade prior to placement of the reservoir base course material: • Minimum grab tensile strength of 250 pounds • Minimum grab failure strain of 50 percent • Minimum seam breaking strength of 140 pounds • Minimum puncture resistance of 310 pounds 3/19/14 Y:\836\002.010\E\UltaBeauty_finalrpt.docx LANDAU ASSOCIATES 3-10 r-I V '' ' • • Minimum tear strength of 50 pounds. The purpose of the geotextile is to prevent upward migration of fines into the porous pavement section. The geotextile should extend upward along the edges in order to completely encapsulate the reservoir base and choker course material. To protect the geotextile, the initial lift of fill over the geotextile should be a minimum of 12 inches thick if heavy construction equipment is utilized. Turning of construction vehicles over the first lift of prepared fill should be avoided. Under no circumstances should construction equipment be allowed on the geotextile fabric before placement of the initial lift of structural fill. If less than 12 inches of reservoir base course is required, the reservoir base course and choker course should be compacted with hand-operated compaction equipment or with smaller vibrating steel drum rollers. In order to provide 30 to 40 percent air voids for storage, the reservoir base course material should consist of a clean, washed, crushed stone meeting the gradational requirements for American Association of State Highway and Transportation Officials (AASHTO) Grading No.3 material. Choker course material should consist of a clean, washed,crushed stone meeting the gradational requirements for AASHTO Grading No. 57. The gradation requirements for AASHTO Grading No. 3 and AASHTO Grading No. 57 are provided in the following table. RESERVOIR BASE COURSE AND CHOKER COURSE GRADATION (PERCENT FINER—BY WEIGHT) Sieve Reservoir Choker Base Course Course Size AASHTO No.3 AASHTO No.57 2''A" 100 - 2" 90-100 - 1W 35-70 100 1" 0-15 95-100 '/" 0-5 25-60 #4 - 0-10 #8 0-5 At least 75 percent of the reservoir base course and choker course material retained on the #4 sieve should have at least one fractured face. The material supplier should be required to submit modified Proctor test results in order to confirm that the reservoir base course material has between 30 and 40 percent air voids when compacted to between 90 and 92 percent of the maximum dry density. Reservoir base course and choker course material should be compacted to between 90 and 92 percent of the maximum dry density determined by ASTM D1557 test procedures. 3/19/14 Y:\836\002.010Ut\U1taBeauty_final rpt.docx LANDAU ASSOCIATES 3-11 • • Aggregate for porous asphalt pavement should be relatively uniform and have a low percentage of fines (percentage of particles by weight passing the U.S. No 200 sieve). Various different aggregate gradations have been utilized for porous pavement. The National Asphalt Pavement Association (2008) recommends the following gradation for porous pavements utilized in roadways. Other aggregate gradations have been successfully utilized for porous pavement. POROUS PAVEMENT AGGREGATE GRADATION Percent Finer Sieve Size (By Weight) 3/4,. 99-100 1/z" 90-98 #4 18-32 #8 3-15 #200 1-5 A stiff asphalt binder, such as PG70-22, is usually utilized for porous pavement. The binder should be between 5'/2 and 6 percent of the pavement section,by weight. 3.4.3 ASPHALT CONCRETE PAVEMENT In the three borings advanced for this study, ACP was observed to range in thickness from about 1'/2 to 21/2 inches. The base course below the ACP was observed to consist of 1'/2 to 4 inches of medium dense, gravelly sand over well compacted fill and glacial till. Existing cracks in the ACP surface appear to be along paving joints and not a result of poor subgrade preparation. Consequently, removal and replacement of the ACP section is not required. Alternatively, filling/sealing of existing cracks followed by a 2-inch asphalt pavement overlay should be sufficient for parking area rehabilitation. In areas where new pavement sections will be constructed, an appropriate asphalt pavement section would be 2 inches of asphalt pavement over 4 inches of crushed surfacing material. For any areas where moderate to high levels of truck traffic is expected, an appropriate asphalt pavement section would be 4 inches of asphalt pavement over 6 inches of crushed surfacing material. Crushed surfacing material should be compacted to at least 95 percent of the maximum dry density (ASTM D 1557) and meet the requirements for Crushed Surfacing Base Course in Section 9-03.9(3) of the 2014 Washington State Department of Transportation (WSDOT) Standard Specifications. The upper 2 inches of crushed surfacing could consist of Crushed Surfacing Top Course to facilitate fine grading of the surface. Asphalt concrete should be hot-mix asphalt class %2-inch with PG58-22 binder. 3/19/14 Y:\836\002.010\R\UItaBeauty_finalrpt.docx LANDAU ASSOCIATES 3-12 • 4.0 REVIEW OF DOCUMENTS AND CONSTRUCTION OBSERVATIONS Landau Associates recommends that we review the geotechnical-related portions of the plans and specifications for the proposed project in advance of project bidding.

The exploration program consisted of three hollow-stem auger borings (B-1 through B-3). The approximate locations of all explorations are shown on the Site and Exploration Plan of the main document (Figure 2). The borings were advanced to depths ranging from about 8 to 111/2 feet (ft) below the ground surface (BGS) using a truck-mounted hollow-stem auger drill rig. Holocene Drilling, Inc. of Puyallup, Washington advanced the borings under subcontract to Landau Associates. The explorations were located approximately in the field by hand-taping from existing physical features. The ground surface elevation at each exploration location was approximated using Google'Earth. The field exploration program was coordinated and monitored by a Landau Associates geotechnical engineer, who also obtained representative soil samples, maintained a detailed record of the observed subsurface soil and groundwater conditions, and described the soil encountered by visual and textural examination. Each representative soil type observed in the explorations was described using the soil classification system shown on Figure A-1, in general accordance with ASTM International(ASTM) D 2488, Standard Recommended Practice for Description of Soils (Visual-Manual Procedure). Boring logs are presented on Figures A-2 through A-4. These logs represent our interpretation of subsurface conditions identified during the field exploration program. The stratigraphic contacts shown on the individual logs represent the approximate boundaries between soil types; actual transitions may be more gradual. The soil and groundwater conditions depicted are only for the specific date and locations reported and, therefore, are not necessarily representative of other locations and times. A further discussion of the soil and groundwater conditions observed in the explorations is contained in the text portion of this report. Bulk representative grab samples of the soil encountered were collected from the explorations. The samples were transported to the Landau Associates laboratory in Edmonds, Washington for the purpose of completing natural moisture and gradation testing. Laboratory testing is discussed in the following section. Soil samples obtained from the explorations will be stored in our laboratory for 30 days after submittal of the final report. After that date, the samples will be disposed of unless arrangements are made to retain them. LABORATORY TESTING Natural moisture content determinations and sieve analyses were conducted in the Landau Associates laboratory in Edmonds, Washington on representative samples recovered from the field 3/19/14 Y:\836\002.010\R\Ulta Beauty_final rpt.docx A-1 LANDAU ASSOCIATES i • explorations for soil classification purposes. Laboratory testing was performed in general accordance with the ASTM standard test procedures described below. The samples were checked against the field log descriptions, which were updated where appropriate in general accordance with ASTM D2487, Standard Test Method for Classification of Soils for Engineering Purposes. Natural moisture content determinations were performed on soil samples recovered from the borings in general accordance with ASTM D2216. The natural moisture content is shown as W=xx (percent of dry weight)at the respective sample depth in the column labeled"Test Data"on the summary logs. Sieve analyses were performed on representative soil samples obtained from the test pits in accordance with ASTM D422 to provide an indication of the grain size distribution. Samples selected for grain size analysis are designated with a"GS"in the column labeled "Test Data" on the summary test pit logs. The results of the grain size analyses are presented in the form of grain size distribution curves on Figure A-5 in this appendix. 3/19/14 Y:\836\002.010\R\Uita Beauty_final rpt.docx A-2 LANDAU ASSOCIATES N.
