SECTION 1: INTRODUCTION This updated geotechnical report was prepared for the sole use of Project Julian LLC for Project West Julian located at 255 West Julian Street in San Jose, California. The location of the site is shown on the Vicinity Map, Figure 1. This report is based on our current understanding of the planned development and discussion with you. As you know, the exact details including the overall levels, above and below grade, are being evaluated. Additional recommendations may be required based on the final development plan. 1.1 PROJECT DESCRIPTION The project will consist of redeveloping the approximately 1.7-acre site for a new mixed-use tower development. The project is still in the very early planning stages. Based on our discussions with you, we understand the new tower will likely have one to three levels of below-grade parking, between 15 to 17 stories above grade with a maximum above grade height of about 208 feet. We anticipate the below-grade and lower two to four above-grade levels will be of concrete construction with steel-frame construction above the concrete podium. The project design will be based on the current 2019 California Building Code (CBC). Structural loads are not available; however, structural loads are expected to be typical for this type of structure. As mentioned, the number of below-grade levels may be one to three levels. For one-, two-, and three-level basements, we estimate cuts will be on the order of 15 to 18 feet, 25 to 28 feet, and 35 to 38 feet, respectively. 1.2 SCOPE OF SERVICES Our scope of services was presented in our previous proposal dated July 26, 2017 and more recent authorization dated January 29, 2020 for a report update. Our investigation consisted of field and laboratory programs to evaluate physical and engineering properties of the subsurface soils, engineering analysis to prepare recommendations for site work and grading, building foundations, flatwork, retaining walls, and pavements, and preparation of this report. Brief descriptions of our exploration and laboratory programs are presented below.

1.3 EXPLORATION PROGRAM Field exploration consisted of three Cone Penetration Tests (CPTs) advanced on August 28, 2017 and two borings drilled on August 31, 2017 and September 1, 2017 with truck-mounted, hollow-stem auger drilling equipment. The CPTs were advanced to depths of approximately 75 to 110 feet; borings were drilled to depths of approximately 69½ to 119½ feet. Seismic shear wave velocity measurements were collected from CPT-2. The borings and CPTs were backfilled with cement grout in accordance with local requirements; exploration permits were obtained as required by local jurisdictions. The approximate locations of our exploratory borings are shown on the Site Plan, Figure 2. Details regarding our field program are included in Appendix A. 1.4 LABORATORY TESTING PROGRAM In addition to visual classification of samples, the laboratory program focused on obtaining data for foundation design and seismic ground deformation estimates. Testing included moisture contents, dry densities, washed sieve analyses, a Plasticity Index test, consolidation tests, and triaxial compression tests. Details regarding our laboratory program are included in Appendix B. 1.5 ENVIRONMENTAL SERVICES Cornerstone Earth Group previously provided environmental services for this project, including a Phase 1 site assessment; environmental findings and conclusions were provided under separate covers. SECTION 2: REGIONAL SETTING 2.1 GEOLOGICAL SETTING The site is located within the Santa Clara Valley, which is a broad alluvial plane between the Santa Cruz Mountains to the southwest and west, and the Diablo Range to the northeast. The San Andreas Fault system, including the Monte Vista-Shannon Fault, exists within the Santa Cruz Mountains and the Hayward and Calaveras Fault systems exist within the Diablo Range. Alluvial soil thicknesses in the area of downtown San Jose are about 500 feet (Rogers & Williams, 1974). 2.2 REGIONAL SEISMICITY While seismologists cannot predict earthquake events, geologists from the U.S. Geological Survey have recently updated earlier estimates from their 2015 Uniform California Earthquake Rupture Forecast (Version 3) publication. The estimated probability of one or more magnitude 6.7 earthquakes (the size of the destructive 1994 Northridge earthquake) expected to occur somewhere in the San Francisco Bay Area has been revised (increased) to 72 percent for the period 2014 to 2043 (Aagaard et al., 2016). The faults in the region with the highest estimated probability of generating damaging earthquakes between 2014 and 2043 are the Hayward

Page 8: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 3

(33%), Rodgers Creek (33%), Calaveras (26%), and San Andreas Faults (22%). In this 30-year period, the probability of an earthquake of magnitude 6.7 or larger occurring is 22 percent along the San Andreas Fault and 33 percent for the Hayward or Rodgers Creek Faults. The faults considered capable of generating significant earthquakes are generally associated with the well-defined areas of crustal movement, which trend northwesterly. The table below presents the State-considered active faults within 25 kilometers of the site. Table 1: Approximate Fault Distances

Fault Name

Distance (miles) (kilometers)

Hayward (Southeast Extension) 5.8 9.3 Monte Vista-Shannon 7.5 12.0

Calaveras 8.5 13.7 Hayward (Total Length) 8.8 14.2

San Andreas (1906) 11.9 19.2 Sargent 14.1 22.7

A regional fault map is presented as Figure 3, illustrating the relative distances of the site to significant fault zones. SECTION 3: SITE CONDITIONS 3.1 SURFACE DESCRIPTION The site is bounded by a vacated portion of Old West Julian Street to the northwest, Terraine Street to the northeast, West Saint James Street to the southeast, and a California State Route 87 on-ramp to the southwest. The site is currently occupied by a six-story commercial structure with a basement on the southeast side. The rest of the site generally consists of an at-grade asphalt parking lot. Landscaping, including mature trees, hedges, and small retaining walls are along the outside perimeter of the site. The site is generally level and graded towards storm drain inlets. Surface pavements generally consisted of 8 inches of asphalt concrete; no aggregate base was encountered below the asphalt concrete. Based on visual observations, the existing pavements are in moderate condition with some distress. 3.2 SUBSURFACE CONDITIONS Below the surface pavements, our explorations generally encountered clayey soils in the upper approximately 50 feet. The clayey soils consisted of very stiff sandy lean clays, stiff to medium stiff lean clays, and hard sandy silty clays. Thin discontinuous strata of loose to medium dense clean sands, poorly graded sands with silt, silty sands, and clayey sands were also interbedded

PROJECT WEST JULIAN 1178-2-2

Page 4

within the clay layer. Stiff clayey soils interbedded with medium dense sands were also encountered after 50 feet in CPT 1 to 75 feet, and to 69½ feet in Boring EB-1. Dense to very dense clean sands, gravelly sands, and poorly graded sands with silt were encountered to about 52 feet in Boring EB-2, and to about 60 feet in CPT-2 and CPT-3. The soils after the dense to very dense sands and gravels to the end of EB-2 at 119½ feet (the maximum depth explored), and CPT-2 at 75 feet, generally consisted of stiff clays with few interbedded sand layers. Clayey soils were encountered after the dense sands and gravels in CPT-2 to about 83 feet when medium dense to dense clean sands and silty sands were encountered. The sands extended to about 93 feet, followed by stiff clays with few interbedded sand layers to the end of the CPT at 110 feet. 3.2.1 Plasticity/Expansion Potential We performed one Plasticity Index (PI) tests on a representative sample. Test results were used to evaluate expansion potential of surficial soils. The results of the surficial PI test indicated a PI of 10, indicating low expansion potential to wetting and drying cycles. 3.2.2 In-Situ Moisture Contents Laboratory testing indicated that the in-situ moisture contents within the upper 35 feet, as well as at basement subgrade elevations, generally range from about 2 to 14 percent over the estimated laboratory optimum moisture. 3.3 GROUNDWATER Groundwater was encountered in our borings at depths ranging from 18 to 21 feet below current grades. In addition, groundwater was inferred by our CPT pore pressure measurements at depths ranging from about 12½ to 14 feet below current grades. All measurements were taken at the time of drilling and may not represent the stabilized levels that can vary from than the initial levels encountered. Historical high groundwater is mapped at approximately 10 feet below existing site grades (California Geologic Survey, San Jose West 7.5-Minute Quadrangle, 2002). According to GeoTracker, monitoring wells previously located near the north corner of Old West Julian Street and Terraine Street (approximately 200 feet north of and at about the same elevation as the site) indicated seasonal groundwater depths ranging from 13 to 18 feet below existing grades between March, 2005 and August, 2012. In general, fluctuations in groundwater levels occur due to many factors including seasonal fluctuation, underground drainage patterns, regional fluctuations, and other factors. Based on the above information, we used a design groundwater depth of 10 feet below current grades for our liquefaction analyses.

SECTION 4: GEOLOGIC HAZARDS 4.1 FAULT RUPTURE As discussed above several significant faults are located within 25 kilometers of the site. The site is not located within a State-designated Alquist Priolo Earthquake Fault Zone, a Santa Clara County Fault Hazard Zone, or a City of San Jose Potential Hazard Zone. Based on review of geologic maps as summarized in Figure 3, no known surface expression of fault traces is thought to cross the site; therefore, fault rupture hazard is not a significant geologic hazard at the site. 4.2 ESTIMATED GROUND SHAKING Moderate to severe (design-level) earthquakes can cause strong ground shaking, which is the case for most sites within the Bay Area. A peak ground acceleration (PGAM) was estimated following the ground motion hazard analysis procedure presented in Chapter 21, Section 21.2 of ASCE 7-16 and Supplement No. 1 and determined in accordance with Section 21.5 of ASCE 7-16. For our liquefaction analysis we used a PGAM of 0.703g. 4.3 LIQUEFACTION POTENTIAL The site is within a State-designated Liquefaction Hazard Zone (CGS, San Jose West Quadrangle, 2002) as well as a Santa Clara County Liquefaction Hazard Zone (Santa Clara County, 2012). Our field and laboratory programs addressed this issue by testing and sampling potentially liquefiable layers to depths of at least 50 feet, performing visual classification on sampled materials, evaluating CPT data, and performing various tests to further classify soil properties. 4.3.1 Background During strong seismic shaking, cyclically induced stresses can cause increased pore pressures within the soil matrix that can result in liquefaction triggering, soil softening due to shear stress loss, potentially significant ground deformation due to settlement within sandy liquefiable layers as pore pressures dissipate, and/or flow failures in sloping ground or where open faces are present (lateral spreading) (NCEER 1998). Limited field and laboratory data is available regarding ground deformation due to settlement; however, in clean sand layers settlement on the order of 2 to 4 percent of the liquefied layer thickness can occur. Soils most susceptible to liquefaction are loose, non-cohesive soils that are saturated and are bedded with poor drainage, such as sand and silt layers bedded with a cohesive cap. 4.3.2 Analysis As discussed in the “Subsurface” section above, several sand layers were encountered below the design groundwater depth of 10 feet. Following the liquefaction analysis framework in the 2008 monograph, Soil Liquefaction During Earthquakes (Idriss and Boulanger, 2008), incorporating updates in CPT and SPT Based Liquefaction Triggering Procedures (Boulanger

Page 11: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 6

and Idriss, 2014), and in accordance with CDMG Special Publication 117A guidelines (CDMG, 2008) for quantitative analysis, these layers were analyzed for liquefaction triggering and potential post-liquefaction settlement. These methods compare the ratio of the estimated cyclic shaking (Cyclic Stress Ratio - CSR) to the soil’s estimated resistance to cyclic shaking (Cyclic Resistance Ratio - CRR), providing a factor of safety against liquefaction triggering. Factors of safety less than or equal to 1.3 are considered to be potentially liquefiable and capable of post-liquefaction re-consolidation (i.e. settlement). The CSR for each layer quantifies the stresses anticipated to be generated due to a design-level seismic event, is based on the peak horizontal acceleration generated at the ground surface discussed in the “Estimated Ground Shaking” section above, and is corrected for overburden and stress reduction factors as discussed in the procedure developed by Seed and Idriss (1971) and updated in the 2008 Idriss and Boulanger monograph. The soil’s CRR is estimated from the in-situ measurements from CPTs and laboratory testing on samples retrieved from our borings. SPT “N” values obtained from hollow-stem auger borings were not used in our analyses, as the “N” values obtained are less reliable in sands below groundwater. The tip pressures are corrected for effective overburden stresses, taking into consideration both the groundwater level at the time of exploration and the design groundwater level, and stress reduction versus depth factors. The CPT method utilizes the soil behavior type index (IC) to estimate the plasticity of the layers. The results of our CPT analyses (CPT-1 to CPT-3) are presented on Figures 4A through 4C of this report. Calculations for these CPTs are attached as Appendix C. 4.3.3 Summary Our analyses indicate that several layers could potentially experience liquefaction triggering that could result in post-liquefaction total settlement based on the Yoshimine (2006) method. Table 3 summarizes estimated total post-liquefaction settlements for one-, two-, and three-levels below-grade. As discussed in SP 117A, differential movement for level ground sites over deep soil sites will be up to about two-thirds of the total settlement between independent foundation elements.

4.3.4 Ground Rupture Potential The methods used to estimate liquefaction settlements assume that there is a sufficient cap of non-liquefiable material to prevent ground rupture or sand boils. For ground rupture to occur, the pore water pressure within the liquefiable soil layer will need to be great enough to break through the overlying non-liquefiable layer, which could cause significant ground deformation and settlement. The work of Youd and Garris (1995) indicates that the approximately 25 feet of surficial, non-liquefiable material is sufficient to prevent ground rupture; therefore, the above total liquefaction settlement estimates are reasonable. 4.4 LATERAL SPREADING Lateral spreading is horizontal/lateral ground movement of relatively flat-lying soil deposits towards a free face such as an excavation, channel, or open body of water; typically lateral spreading is associated with liquefaction of one or more subsurface layers near the bottom of the exposed slope. As failure tends to propagate as block failures, it is difficult to analyze and estimate where the first tension crack will form. There are no open faces within a distance considered susceptible to lateral spreading; therefore, in our opinion, the potential for lateral spreading to affect the site is low. 4.5 SEISMIC SETTLEMENT/UNSATURATED SAND SHAKING Loose unsaturated sandy soils can settle during strong seismic shaking. As the soils encountered at the site were predominantly stiff to very stiff clays and medium dense to dense sands, in our opinion, the potential for significant differential seismic settlement affecting the proposed improvements is low. 4.6 TSUNAMI/SEICHE The terms tsunami or seiche are described as ocean waves or similar waves usually created by undersea fault movement or by a coastal or submerged landslide. Tsunamis may be generated at great distance from shore (far field events) or nearby (near field events). Waves are formed, as the displaced water moves to regain equilibrium, and radiates across the open water, similar to ripples from a rock being thrown into a pond. When the waveform reaches the coastline, it quickly raises the water level, with water velocities as high as 15 to 20 knots. The water mass, as well as vessels, vehicles, or other objects in its path create tremendous forces as they impact coastal structures. Tsunamis have affected the coastline along the Pacific Northwest during historic times. The Fort Point tide gauge in San Francisco recorded approximately 21 tsunamis between 1854 and 1964. The 1964 Alaska earthquake generated a recorded wave height of 7.4 feet and drowned eleven people in Crescent City, California. For the case of a far-field event, the Bay area would have hours of warning; for a near field event, there may be only a few minutes of warning, if any.

A tsunami or seiche originating in the Pacific Ocean would lose much of its energy passing through San Francisco Bay. Based on the study of tsunami inundation potential for the San Francisco Bay Area (Ritter and Dupre, 1972), areas most likely to be inundated are marshlands, tidal flats, and former bay margin lands that are now artificially filled, but are still at or below sea level, and are generally within 1½ miles of the shoreline. The site is approximately 8 miles inland from the San Francisco Bay shoreline, and is approximately 80 feet above mean sea level. Therefore, the potential for inundation due to tsunami or seiche is considered low. 4.7 FLOODING Based on our internet search of the Federal Emergency Management Agency (FEMA) flood map public database, the southwest portion of the site is located within Zone X, “Areas of 0.2% annual chance flood; areas of 1% annual chance flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 1% annual chance flood.” The northeast portion of the site is located within Zone D, “Areas in which flood hazards are undetermined, but possible.” We recommend the project civil engineer be retained to confirm this information and verify the base flood elevation, if appropriate. SECTION 5: CONCLUSIONS 5.1 SUMMARY From a geotechnical viewpoint, the project is feasible provided the concerns listed below are addressed in the project design. Descriptions of each concern with brief outlines of our recommendations follow the listed concerns. Potential for significant static settlement Potential for liquefaction-induced settlements Dewatering considerations Presence of unstable basement subgrade soils Proximity to existing improvements and structures Shoring considerations for the below-grade excavation Construction dewatering induced settlements Hydrostatic pressure and uplift Differential movement at on-grade to on-structure transitions

5.1.1 Potential for Significant Static Settlement We evaluated immediate and long-term consolidation settlement due to static building loads using estimated interior column loading of about 2,100 kips. For a rigid mat foundation, total static settlement was estimated to range up to approximately 3⅔, 3¼, and 2½ inches for one-level below grade, two levels below grade, and three levels below grade without ground

improvement, respectively. Additional recommendations are provided in the “Foundation” sections of this report. 5.1.2 Potential for Liquefaction-Induced Settlements As discussed, our liquefaction analysis indicates that there is a potential for liquefaction of localized sand layers during a significant seismic event. Although the potential for liquefied sands to vent to the ground surface through cracks in the surficial soils is considered low, our analysis indicates that liquefaction-induced settlement up to 1½ inches could occur, resulting in differential settlement up to 1 inch. Based on the above, and to mitigate the combined total and differential seismic and static settlements, we recommend the structure be supported on reinforced concrete mat foundations over ground improvement or on deep foundations. Detailed foundation recommendations are presented in the “Foundations” section. 5.1.3 Dewatering Considerations As discussed, shallow groundwater was measured in our borings ranging from 18 to 21 feet below current grades, and pore pressure dissipation tests performed in our CPTs inferred groundwater at depths ranging from about 12½ to 14 feet. Based on historic high groundwater produced by CGS and our own data and experience in the area, we estimate historic high groundwater to be at approximately 10 feet below existing site grades. For this project, we recommend a design groundwater depth of 10 feet. If it is desired to document the fluctuation of the groundwater before construction, we recommend installing at least one groundwater observation well at the site. Our experiences with similar sites in the vicinity indicate that shallow groundwater could significantly impact underground construction. These impacts typically consist of potentially wet excavated soils, difficulty achieving compaction, and difficult underground utility installation. Dewatering and shoring of deeper utility trenches may be required in some isolated areas of the site. Detailed recommendations addressing this concern are presented in the “Earthwork” section of this report. 5.1.4 Presence of Unstable Basement Subgrade Soils As groundwater was encountered as shallow as 18 feet below current grades in our borings, the excavations for the below-grade parking structure will encounter groundwater. The fully saturated clays at these depths will likely have high moisture contents and variable strengths, and may become unstable under the weight of track-mounted or rubber-tired construction equipment. To provide a firm base for construction of the garage basement foundation, it may be necessary to remove and replace an additional approximately 12 to 18 inches of native soil below the basement foundation level and replace it with a bridging layer, such as crushed rock, or to chemically treat the exposed soil with lime or cement. Otherwise, a layer of lean sand-cement slurry or concrete layer (“rat slab”) may be considered or a combination of the two. Temporary dewatering to a depth of at least 5 feet below the bottom of the building excavation is recommended during construction.

5.1.5 Proximity to Existing Improvements and Structures As previously mentioned, the site is bounded by a California State Route 87 on-ramp to the southwest. In addition, an existing two-story structure is about 125 feet northeast of the site, and construction nearby along Terraine Street and Old West Julian Street may indicate future development. The temporary shoring will need to accommodate loading from the adjacent streets and potentially new buildings from the nearby construction sites, and provide for limited movement of the improvements to reduce the potential for distress. Restrained shoring will be required to limit deflections at the top of the excavation that could result in settlement of the adjacent foundations, streets, and utilities. Support of the adjacent existing improvements such as streets, sidewalks, and utilities without distress should be the contractor’s responsibility. We recommend that the contractor implement a monitoring program to determine the effects of the construction on nearby improvements, including the monitoring of cracking and vertical movement of adjacent structures, and nearby streets, sidewalks, utilities, and other improvements. In critical areas, we recommend that inclinometers or other instrumentation be installed as part of the shoring system to closely monitor lateral movement. Detailed shoring recommendations are also provided in this report. 5.1.6 Shoring Considerations for the Below-Grade Excavation Excavations ranging from 15 to 35 feet deep is expected for the various below-grade parking garage options. The primary considerations in selecting a suitable shoring system typically include 1) control of vertical and lateral ground surface or wall movements, 2) constructability, 3) dewatering, and 4) cost. There are several possible methods of providing lateral support for the excavation. Additional recommendations can be provided once the shoring method has been determined. 5.1.7 Construction Dewatering Induced Settlements We evaluated the potential settlement of the surrounding ground for a three-level below-grade parking garage with dewatering to at least 5 feet below the bottom of the mass excavation. Our analysis assumed a maximum dewatering depth of 45 feet, resulting in up to about 2 inches of settlement near well points, decreasing at greater distances from well points. If this settlement is considered tolerable to nearby improvements, dewatering should be feasible. If settlement due to dewatering is not desired, the shoring can be designed as undrained cutoff walls, with secant soil-cement columns or similar. Further discussion on construction dewatering may be found below in Section 6. 5.1.8 Hydrostatic Pressure and Uplift We anticipate that the groundwater levels may be as high as 10 feet below current grades. The below-grade garage slab will need to be designed to resist uplift forces resulting from hydrostatic pressures, the basement walls designed to resist hydrostatic pressure, and the

Page 16: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 11

entire structure checked for uplift loading. Based on the design groundwater level and the estimated bottom of the basement excavation, a hydrostatic pressure would need to be considered for uplift resistance design by the project structural engineer. 5.1.9 Differential Movement at On-grade to On-Structure Transitions We anticipate that some improvements will transition from on-grade support to overlying the below-grade garage levels. Where the depth of soil cover overlying the below-grade parking structure roof is thin or where below-grade walls extend to within inches of finished grade, these transition areas typically experience increased differential movement due to a variety of causes, including difficulty in achieving compaction of retaining wall backfill closest to the wall. If surface improvements are included that are highly sensitive to differential movement, additional measures should be considered, such as doweling to the structure, additional reinforcing, or reduced construction and control joint spacing for concrete flatwork. 5.2 PLANS AND SPECIFICATIONS REVIEW We recommend that we be retained to review the geotechnical aspects of the project structural, civil, and landscape plans and specifications, allowing sufficient time to provide the design team with any comments prior to issuing the plans for construction. 5.3 CONSTRUCTION OBSERVATION AND TESTING As site conditions may vary significantly between the small-diameter borings performed during this investigation, we also recommend that a Cornerstone representative be present to provide geotechnical observation and testing during earthwork and foundation construction. This will allow us to form an opinion and prepare a letter at the end of construction regarding contractor compliance with project plans and specifications, and with the recommendations in our report. We will also be allowed to evaluate any conditions differing from those encountered during our investigation, and provide supplemental recommendations as necessary. For these reasons, the recommendations in this report are contingent of Cornerstone providing observation and testing during construction. Contractors should provide at least a 48-hour notice when scheduling our field personnel. SECTION 6: EARTHWORK 6.1 SITE DEMOLITION All existing improvements not to be reused for the current development, including all foundations, flatwork, pavements, utilities, and other improvements should be demolished and removed from the site. Recommendations in this section apply to the removal of these improvements, which are currently present on the site, prior to the start of mass grading or the construction of new improvements for the project. Cornerstone should be notified prior to the start of demolition, and should be present on at least a part-time basis during all backfill and mass grading as a result of demolition. Occasionally,

Page 17: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 12

other types of buried structures (wells, cisterns, debris pits, etc.) can be found on sites with prior development. If encountered, Cornerstone should be contacted to address these types of structures on a case-by-case basis prior to their demolition. 6.1.1 Demolition of Existing Slabs, Foundations and Pavements All slabs, foundations, and pavements should be completely removed from within planned building areas. As an owner value-engineered option (if applicable), existing slabs, foundations, and pavements that extend into planned flatwork, pavement, or landscape areas may be left in place provided there is at least 3 feet of engineered fill overlying the remaining materials, they are shown not to conflict with new utilities, and that asphalt and concrete more than 10 feet square is broken up to allow subsurface drainage. Future distress and/or higher maintenance may result from leaving these prior improvements in place. A discussion of recycling existing improvements is provided later in this report. As previously mentioned, the existing building has a basement; however, it is unknown if the basement is within the footprint of the at-grade portion of the existing building. If any portion of the basement extends outside of the proposed below-grade parking structure, it will need to be backfilled up to current grades. The upper 3 feet of the abandoned basement walls below future improvements should also be removed. If flatwork is proposed in these areas, then the walls of the existing basement area should be sloped at least 2:1 (horizontal:vertical), as room allows, to avoid any abrupt transitions from fill to current grades. 6.1.2 Abandonment of Existing Utilities All utilities should be completely removed from within planned building areas. For any utility line to be considered acceptable to remain within building areas, the utility line must be completely backfilled with grout or sand-cement slurry (sand slurry is not acceptable), the ends outside the building area capped with concrete, and the trench fills either removed and replaced as engineered fill with the trench side slopes flattened to at least 1:1, or the trench fills are determined not to be a risk to the structure. The assessment of the level of risk posed by the particular utility line will determine whether the utility may be abandoned in place or needs to be completely removed. The contractor should assume that all utilities will be removed from within building areas unless provided written confirmation from both the owner and the geotechnical engineer. Utilities extending beyond the building area may be abandoned in place provided the ends are plugged with concrete, they do not conflict with planned improvements, and that the trench fills do not pose significant risk to the planned surface improvements. The risk for owners associated with abandoning utilities in place include the potential for future differential settlement of existing trench fills, and/or partial collapse and potential ground loss into utility lines that are not completely filled with grout.

6.2 SITE CLEARING AND PREPARATION 6.2.1 Site Stripping The site should be stripped of all surface vegetation, and surface and subsurface improvements to be removed within the proposed development area. Demolition of existing improvements is discussed in the prior paragraphs. Surface vegetation and topsoil should be stripped to a sufficient depth to remove all material greater than 3 percent organic content by weight. Based on our site observations, surficial stripping should extend about 3 to 6 inches below existing grade in vegetated areas. 6.2.2 Tree and Shrub Removal Trees and shrubs designated for removal should have the root balls and any roots greater than ½-inch diameter removed completely. Mature trees are estimated to have root balls extending to depths of 2 to 4 feet, depending on the tree size. Significant root zones are anticipated to extend to the diameter of the tree canopy. Grade depressions resulting from root ball removal should be cleaned of loose material and backfilled in accordance with the recommendations in the “Compaction” section of this report. 6.3 REMOVAL OF EXISTING FILLS Undocumented fills were not encountered in our borings; however, any fills encountered during site grading will likely be removed during excavation of the below-grade parking structure. Provided the fills meet the “Material for Fill” requirements below, the fills may be reused when backfilling excavations. If materials are encountered that do not meet the requirements, such as debris, wood, trash, those materials should screened out of the remaining material and be removed from the site. Backfill of excavations should be placed in lifts and compacted in accordance with the “Compaction” section below. Any remaining fills extending into planned pavement and flatwork areas may be left in place provided they are determined to be a low risk for future differential settlement and that the upper 12 to 18 inches of fill below pavement subgrade is re-worked and compacted as discussed in the “Compaction” section below. 6.4 TEMPORARY CUT AND FILL SLOPES The contractor is responsible for maintaining all temporary slopes and providing temporary shoring where required. Temporary shoring, bracing, and cuts/fills should be performed in accordance with the strictest government safety standards. On a preliminary basis, the upper 35 feet at the site may be classified as OSHA Site C materials. Recommended soil parameters for temporary shoring are provided in the “Temporary Shoring” section of this report. Excavations extending more than 5 feet below building subgrade and excavations in pavement and flatwork areas should be sloped in accordance with the OSHA soil classification.

Page 14

6.5 BELOW-GRADE EXCAVATIONS Below-grade excavations may be constructed with temporary slopes in accordance with the “Temporary Cut and Fill Slopes” section above if space allows. Alternatively, temporary shoring may support the planned cuts. We have provided geotechnical parameters for shoring design in the section below. The choice of shoring method should be left to the contractor’s judgment based on experience, economic considerations and adjacent improvements such as utilities, pavements, and foundation loads. Temporary shoring should support adjacent improvements without distress and should be the contractor’s responsibility. A pre-condition survey including photographs and installation of monitoring points for existing site improvements should be included in the contractor’s scope. We should be provided the opportunity to review the geotechnical parameters of the shoring design prior to implementation; the project structural engineer should be consulted regarding support of adjacent structures. 6.5.1 Temporary Shoring Based on the site conditions encountered during our investigation, the cuts may be supported by soldier beams and tie-backs, braced excavations, soil nailing, or potentially other methods. Where shoring will extend more than about 10 feet, restrained shoring will most likely be required to limit detrimental lateral deflections and settlement behind the shoring. In addition to soil earth pressures, the shoring system will need to support adjacent loads such as construction vehicles and incidental loading, existing structure foundation loads, and street loading. We recommend that heavy construction loads (cranes, etc.) and material stockpiles be kept at least 15 feet behind the shoring. Where this loading cannot be set back, the shoring will need to be designed to support the loading. The shoring designer should provide for timely and uniform mobilization of soil pressures that will not result in excessive lateral deflections. Minimum suggested geotechnical parameters for shoring design are provided in the table below. Table 3: Suggested Temporary Shoring Design Parameters

Design Parameter Design Value Minimum Lateral Wall Surcharge (upper 5 feet) 120 psf 1Restrained Wall – Trapezoidal Earth Pressure Increase from 0 to 25H psf 2Passive Pressure – Starting at 2 feet below the bottom of the excavation

1 H equals the height of the excavation 2 Passive pressures are assumed to act over twice the soldier pile diameter The restrained earth pressure may also be calculated distributed as described in Figure 23 of the FHWA Circular No. 4 – Ground Anchors and Anchored Systems. If shotcrete lagging is used for the shoring facing, the permanent retaining wall drainage materials, as discussed in the “Wall Drainage” section of this report, will need to be installed during temporary shoring construction. At a minimum, 2-foot-wide vertical panels should be

Page 20: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 15

placed between soil nails or tiebacks that are spaced at 6-foot centers. For 8-foot centers, 4-foot-wide vertical panels should be provided. A horizontal strip drain connecting the vertical panels should be provided, or pass-through connections should be included for each vertical panel. We performed our borings with hollow-stem auger drilling equipment and as such were not able to evaluate the potential for caving soils, which can create difficult conditions during soldier beam, tie-back, or soil nail installation; caving soils can also be problematic during excavation and lagging placement. The contractor is responsible for evaluating excavation difficulties prior to construction. Where relatively clean sands (especially encountered below groundwater) or difficult drilling or cobble conditions were encountered during our exploration, pilot holes performed by the contractor may be desired to further evaluate these conditions prior to the finalization of the shoring budget. In addition to anticipated deflection of the shoring system, other factors such as voids created by soil sloughing, and erosion of granular layers due to perched water conditions can create adverse ground subsidence and deflections. The contractor should attempt to cut the excavation as close to neat lines as possible; where voids are created they should be backfilled as soon as possible with sand, gravel, or grout. As previously mentioned, we recommend that a monitoring program be developed and implemented to evaluate the effects of the shoring on adjacent improvements. All sensitive improvements should be located and monitored for horizontal and vertical deflections and distress cracking based on a pre-construction survey. For multi-level excavations, the installation of inclinometers at critical areas may be desired for more detailed deflection monitoring. The monitoring frequency should be established and agree to by the project team prior to start of shoring construction. The above recommendations are for the use of the design team; the contractor in conjunction with input from the shoring designer should perform additional subsurface exploration they deem necessary to design the chosen shoring system. A California-licensed civil or structural engineer must design and be in responsible charge of the temporary shoring design. The contractor is responsible for means and methods of construction, as well as site safety. 6.5.2 Construction Dewatering As previously discussed, historic high groundwater levels are above the potential planned excavation depths; therefore, temporary dewatering will likely be necessary during construction. Temporary dewatering for construction should be the responsibility of the contractor. The selection of equipment and methods of dewatering should be left up to the contractor and, due to the variable nature of the subsurface conditions in the downtown San Jose area, they should be aware that modifications to the dewatering system, such as adding well points, may be required during construction depending on the conditions encountered. We recommend that any dewatering of the site be carried out in such a manner as to maintain the groundwater a minimum of 5 feet below the bottom of the mass excavation. The contractor

Page 21: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 16

should design a system to achieve this criteria. Additionally, the groundwater should be maintained a minimum of 2 feet below all local excavations for deepened foundations, utilities or other structures. Should dewatering be temporarily shut down, it could have considerable detrimental effects on the excavations, including flooding, destabilization of the bottom of the excavation, shoring failures, etc. Therefore, we recommend that consideration be given to having the dewatering contractor provide backup power in case of loss of power or other redundancies, as deemed necessary. In addition, drawdown of groundwater during dewatering can cause subsidence outside of the excavation area. We estimate that limiting drawdown to a maximum of 45 feet below existing grade would cause subsidence on the order of 2 inches. If less subsidence is desired, then less drawdown should be considered, or the shoring can be designed as undrained cutoff walls, with secant soil-cement columns or similar. If drawdown to greater than 45 feet is desired, we recommend that the affects be further evaluated. Special considerations may be required prior to discharge of groundwater from dewatering activities depending on the environmental impacts at the site. These requirements may include storage and testing under permit prior to discharge. Impacted groundwater may require discharge at an offsite facility. 6.6 SUBGRADE PREPARATION After site clearing and demolition is complete, and prior to backfilling any excavations resulting from fill removal or demolition, the excavation subgrade and subgrade within areas to receive additional site fills, slabs-on-grade and/or pavements should be scarified to a depth of 6 inches, moisture conditioned, and compacted in accordance with the “Compaction” section below. The subgrade for any slab or mat foundation extending to or below ground water (i.e. the basement level) should generally be cut to the desired grades, including the thickness for any subgrade stabilization, as discussed below. 6.7 SUBGRADE STABILIZATION MEASURES Soil subgrade and fill materials, especially soils with high fines contents such as clays and silty soils, can become unstable due to high moisture content, whether from high in-situ moisture contents or from winter rains. As the moisture content increases over the laboratory optimum, it becomes more likely the materials will be subject to softening and yielding (pumping) from construction loading or become unworkable during placement and compaction. As discussed in the “Subsurface” section in this report, the in-situ moisture contents are about 2 to 14 percent over the estimated laboratory optimum in the upper 45 feet of the soil profile. The contractor should anticipate drying the soils prior to reusing them as fill. In addition, as mentioned above, the bottom of the garage excavation may consist of saturated native soils; repetitive rubber-tire loading will likely de-stabilize the soils.

Page 22: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 17

Even presuming that temporary dewatering will be included for the below-grade parking garage excavation, the soils above the depressed water table can be wet and difficult to work with. There are several methods to address potential unstable soil conditions and facilitate fill placement and trench backfill. Some of the methods are briefly discussed below. These recommendations are meant for near-surface soils; additional recommendations are provided below for the bottom of the garage excavation. Implementation of the appropriate stabilization measures should be evaluated on a case-by-case basis according to the project construction goals and the particular site conditions. 6.7.1 Removal and Replacement As an alternative to scarification, the contractor may choose to over-excavate the unstable soils and replace them with dry on-site or import materials. A Cornerstone representative should be present to provide recommendations regarding the appropriate depth of over-excavation, whether a geosynthethic (stabilization fabric or geogrid) is recommended, and what materials are recommended for backfill. 6.7.2 Chemical Treatment Where the unstable area exceeds about 5,000 to 10,000 square feet and/or site winterization is desired, chemical treatment with quicklime (CaO), kiln-dust, or cement may be more cost-effective than removal and replacement. Recommended chemical treatment depths will typically range from 12 to 18 inches depending on the magnitude of the instability. 6.7.3 Scarification and Drying For at-grade improvements subgrade may be scarified to a depth of 12 to 18 inches and allowed to dry to near optimum conditions, if sufficient dry weather is anticipated to allow sufficient drying. More than one round of scarification may be needed to break up the soil clods. 6.7.4 Below-Grade Excavation Stabilization As previously mentioned, the in-situ moisture contents of the soils at basement subgrade elevation may be up to 14 percent or greater over the estimated laboratory optimum moisture. In addition, the planned basement excavation will extend below the current groundwater level. Therefore, we recommend that the contractor plan to excavate an additional 12 to 18 inches below subgrade, place a layer of stabilization fabric (Mirafi RS380i, or equivalent) at the bottom, and backfill with clean, crushed rock. The crushed rock should be consolidated in place with light vibratory equipment. Rubber-tire equipment should not be allowed to operate on the exposed subgrade; the crushed rock should be stockpiled, then pushed and spread out over the stabilization fabric. If desired, chemically treating the exposed soil with lime or cement, or the use of a “rat slab,” is also feasible for the basement subgrade. Due to the anticipated excavation, it may be more advantageous and cost-effective than removal and replacement.

6.8 MATERIAL FOR FILL 6.8.1 Re-Use of On-site Soils On-site soils with an organic content less than 3 percent by weight may be reused as general fill. General fill should not have lumps, clods or cobble pieces larger than 6 inches in diameter; 85 percent of the fill should be smaller than 2½ inches in diameter. Minor amounts of oversize material (smaller than 12 inches in diameter) may be allowed provided the oversized pieces are not allowed to nest together and the compaction method will allow for loosely placed lifts not exceeding 12 inches. 6.8.2 Re-Use of On-Site Site Improvements Asphalt concrete (AC) grindings and aggregate base (AB) may be generated during site demolition. If the AC grindings are mixed with the underlying AB to meet Class 2 AB specifications, they may be reused within the new pavement and flatwork structural sections. AC/AB grindings may not be reused within the building areas. Laboratory testing will be required to confirm the grindings meet project specifications. 6.8.3 Potential Import Sources Imported and non-expansive material should be inorganic with a Plasticity Index (PI) of 15 or less, and not contain recycled asphalt concrete where it will be used within the proposed building areas. To prevent significant caving during trenching or foundation construction, imported material should have sufficient fines. Samples of potential import sources should be delivered to our office at least 10 days prior to the desired import start date. Information regarding the import source should be provided, such as any site geotechnical reports. If the material will be derived from an excavation rather than a stockpile, potholes will likely be required to collect samples from throughout the depth of the planned cut that will be imported. At a minimum, laboratory testing will include PI tests. Material data sheets for select fill materials (Class 2 aggregate base, ¾-inch crushed rock, quarry fines, etc.) listing current laboratory testing data (not older than 6 months from the import date) may be provided for our review without providing a sample. If current data is not available, specification testing will need to be completed prior to approval. Environmental and soil corrosion characterization should also be considered by the project team prior to acceptance. Suitable environmental laboratory data to the planned import quantity should be provided to the project environmental consultant; additional laboratory testing may be required based on the project environmental consultant’s review. The potential import source should also not be more corrosive than the on-site soils, based on pH, saturated resistivity, and soluble sulfate and chloride testing. 6.9 COMPACTION REQUIREMENTS All fills, and subgrade areas where fill, slabs-on-grade, and pavements are planned, should be placed in loose lifts 8 inches thick or less and compacted in accordance with ASTM D1557

Page 24: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 19

(latest version) requirements as shown in the table below. In general, clayey soils should be compacted with sheepsfoot equipment and sandy/gravelly soils with vibratory equipment; open-graded materials such as crushed rock should be placed in lifts no thicker than 18 inches consolidated in place with vibratory equipment. Each lift of fill and all subgrade should be firm and unyielding under construction equipment loading in addition to meeting the compaction requirements to be approved. The contractor (with input from a Cornerstone representative) should evaluate the in-situ moisture conditions, as the use of vibratory equipment on soils with high moistures can cause unstable conditions. General recommendations for soil stabilization are provided in the “Subgrade Stabilization Measures” section of this report. Table 4: Compaction Requirements

The contractor should keep all exposed expansive soil subgrade (and also trench excavation side walls) moist until protected by overlying improvements (or trenches are backfilled). If expansive soils are allowed to dry out significantly, re-moisture conditioning may require several days of re-wetting (flooding is not recommended), or deep scarification, moisture conditioning, and re-compaction.

Page 20

6.10 TRENCH BACKFILL Utility lines constructed within public right-of-way should be trenched, bedded and shaded, and backfilled in accordance with the local or governing jurisdictional requirements. Utility lines in private improvement areas should be constructed in accordance with the following requirements unless superseded by other governing requirements. All utility lines should be bedded and shaded to at least 6 inches over the top of the lines with crushed rock (⅜-inch-diameter or greater) or well-graded sand and gravel materials conforming to the pipe manufacturer’s requirements. Open-graded shading materials should be consolidated in place with vibratory equipment and well-graded materials should be compacted to at least 90 percent relative compaction with vibratory equipment prior to placing subsequent backfill materials. General backfill over shading materials may consist of on-site native materials provided they meet the requirements in the “Material for Fill” section, and are moisture conditioned and compacted in accordance with the requirements in the “Compaction” section. Where utility lines will cross perpendicular to strip footings, the footing should be deepened to encase the utility line, providing sleeves or flexible cushions to protect the pipes from anticipated foundation settlement, or the utility lines should be backfilled to the bottom of footing with sand-cement slurry or lean concrete. Where utility lines will parallel footings and will extend below the “foundation plane of influence,” an imaginary 1:1 plane projected down from the bottom edge of the footing, either the footing will need to be deepened so that the pipe is above the foundation plane of influence or the utility trench will need to be backfilled with sand-cement slurry or lean concrete within the influence zone. Sand-cement slurry used within foundation influence zones should have a minimum compressive strength of 75 psi. 6.11 SITE DRAINAGE Ponding should not be allowed adjacent to building foundations, slabs-on-grade, or pavements. Hardscape surfaces should slope at least 2 percent towards suitable discharge facilities; landscape areas should slope at least 3 percent towards suitable discharge facilities. Roof runoff should be directed away from building areas in closed conduits, to approved infiltration facilities, or on to hardscaped surfaces that drain to suitable facilities. Retention, detention or infiltration facilities should be spaced at least 10 feet from buildings, and preferably at least 5 feet from slabs-on-grade or pavements. However, if retention, detention or infiltration facilities are located within these zones, we recommend that these treatment facilities meet the requirements in the Storm Water Treatment Design Considerations section of this report. 6.12 LOW-IMPACT DEVELOPMENT (LID) IMPROVEMENTS The Municipal Regional Permit (MRP) requires regulated projects to treat 100 percent of the amount of runoff identified in Provision C.3.d from a regulated project’s drainage area with low impact development (LID) treatment measures onsite or at a joint stormwater treatment facility. LID treatment measures are defined as rainwater harvesting and use, infiltration,

Page 26: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 21

evapotranspiration, or biotreatment. A biotreatment system may only be used if it is infeasible to implement harvesting and use, infiltration, or evapotranspiration at a project site. Technical infeasibility of infiltration may result from site conditions that restrict the operability of infiltration measures and devices. Various factors affecting the feasibility of infiltration treatment may create an environmental risk, structural stability risk, or physically restrict infiltration. The presence of any of these limiting factors may render infiltration technically infeasible for a proposed project. To aid in determining if infiltration may be feasible at the site, we provide the following site information regarding factors that may aid in determining the feasibility of infiltration facilities at the site. The near-surface soils at the site are clayey, and categorized as Hydrologic Soil Group

D, and is expected to have infiltration rates of less than 0.2 inches per hour. In our opinion, these clayey soils will significantly limit the infiltration of stormwater.

Locally, seasonal high groundwater is mapped at a depth of 10 feet, and therefore is expected to be within the base of the infiltration measure.

The site is known to have pollutants with the potential for mobilization as a result of stormwater infiltration.

In our opinion, infiltration locations within 10 feet of the buildings would create a geotechnical hazard.

6.12.1 Storm Water Treatment Design Considerations If storm water treatment improvements, such as shallow bio-retention swales, basins or pervious pavements, are required as part of the site improvements to satisfy Storm Water Quality (C.3) requirements, we recommend the following items be considered for design and construction. 6.12.1.1 General Bioswale Design Guidelines

If possible, avoid placing bioswales or basins within 10 feet of the building perimeter or

within 5 feet of exterior flatwork or pavements. If bioswales must be constructed within these setbacks, the side(s) and bottom of the trench excavation should be lined with 10-mil visqueen to reduce water infiltration into the surrounding expansive clay.

Bioswales constructed within 3 feet of proposed buildings may be within the foundation zone of influence for perimeter wall loads. Therefore, where bioswales will parallel foundations and will extend below the “foundation plane of influence,” an imaginary 1:1 plane projected down from the bottom edge of the foundation, the foundation will need to be deepened so that the bottom edge of the bioswale filter material is above the foundation plane of influence

Page 27: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 22

The bottom of bioswale or detention areas should include a perforated drain placed at a low point, such as a shallow trench or sloped bottom, to reduce water infiltration into the surrounding soils near structural improvements, and to address the low infiltration capacity of the on-site clay soils.

6.12.1.2 Bioswale Infiltration Material Gradation specifications for bioswale filter material, if required, should be specified on

the grading and improvement plans.

Compaction requirements for bioswale filter material in non-landscaped areas or in pervious pavement areas, if any, should be indicated on the plans and specifications to satisfy the anticipated use of the infiltration area.

If required, infiltration (percolation) testing should be performed on representative samples of potential bioswale materials prior to construction to check for general conformance with the specified infiltration rates.

It should be noted that multiple laboratory tests may be required to evaluate the properties of the bioswale materials, including percolation, landscape suitability and possibly environmental analytical testing depending on the source of the material. We recommend that the landscape architect provide input on the required landscape suitability tests if bioswales are to be planted.

If bioswales are to be vegetated, the landscape architect should select planting materials that do not reduce or inhibit the water infiltration rate, such as covering the bioswale with grass sod containing a clayey soil base.

If required by governing agencies, field infiltration testing should be specified on the grading and improvement plans. The appropriate infiltration test method, duration and frequency of testing should be specified in accordance with local requirements.

Due to the relatively loose consistency and/or high organic content of many bioswale filter materials, long-term settlement of the bioswale medium should be anticipated. To reduce initial volume loss, bioswale filter material should be wetted in 12 inch lifts during placement to pre-consolidate the material. Mechanical compaction should not be allowed, unless specified on the grading and improvement plans, since this could significantly decrease the infiltration rate of the bioswale materials.

It should be noted that the volume of bioswale filter material may decrease over time depending on the organic content of the material. Additional filter material may need to be added to bioswales after the initial exposure to winter rains and periodically over the life of the bioswale areas, as needed.

6.12.1.3 Bioswale Construction Adjacent to Pavements If bio-infiltration swales or basins are considered adjacent to proposed parking lots or exterior flatwork, we recommend that mitigative measures be considered in the design and construction of these facilities to reduce potential impacts to flatwork or pavements. Exterior flatwork, concrete curbs, and pavements located directly adjacent to bio-swales may be susceptible to settlement or lateral movement, depending on the configuration of the bioswale and the setback between the improvements and edge of the swale. To reduce the potential for distress to these improvements due to vertical or lateral movement, the following options should be considered by the project civil engineer: Improvements should be setback from the vertical edge of a bioswale such that there is

at least 1 foot of horizontal distance between the edge of improvements and the top edge of the bioswale excavation for every 1 foot of vertical bioswale depth, or

Concrete curbs for pavements, or lateral restraint for exterior flatwork, located directly adjacent to a vertical bioswale cut should be designed to resist lateral earth pressures in accordance with the recommendations in the “Retaining Walls” section of this report, or concrete curbs or edge restraint should be adequately keyed into the native soil or engineered to reduce the potential for rotation or lateral movement of the curbs.

6.13 LANDSCAPE CONSIDERATIONS We recommend reducing the amount of surface water infiltrating soils near foundations and exterior slabs-on-grade. This can typically be achieved by: Using drip irrigation

Avoiding open planting within 3 feet of the building perimeter or near the top of existing

slopes Regulating the amount of water distributed to lawns or planter areas by using irrigation

timers

Selecting landscaping that requires little or no watering, especially near foundations. We recommend that the landscape architect consider these items when developing landscaping plans. SECTION 7: 2019 CBC SEISMIC DESIGN CRITERIA We developed site-specific design parameters in accordance with Chapter 16, Chapter 18 and Appendix J of the 2019 California Building Code (CBC) and Chapters 11, 12, 20 and 21 and Supplement No. 1 of ASCE 7-16.

7.1 SITE LOCATION AND PROVIDED DATA FOR 2019 CBC SEISMIC DESIGN The project is located at latitude 37.338368° and longitude -121.897152°, which is based on Google Earth (WGS84) coordinates at the approximate center of the site at 255 West Julian Street in San Jose, California. We have assumed that a Seismic Importance Factor (Ie) of 1.00 has been assigned to the structure in accordance with Table 1.5-2 of ASCE 7-16 for structures classified as Risk Category II. The building period has not been provided by the project structural engineer. 7.2 SITE CLASSIFICATION – CHAPTER 20 OF ASCE 7-16 Code-based site classification and ground motion attenuation relationships are based on the time-weighted average shear wave velocity of the top approximately 100 feet (30 meters) of the soil profile, or VS30. Shear wave velocity (VS) measurements were performed while advancing CPT-2, resulting in a time-averaged shear wave velocity for the top 30 meters (VS30) of 714 feet per second (or 218 meters per second). Provided ground improvement is performed to densify the soil and mitigate the higher seismic settlements beneath a structure with a basement shallower than about 35 feet beneath the surface, we recommend the site be classified as Soil Classification D, which is described as a “stiff soil” profile. Because we used site specific data from our explorations and laboratory testing, the site class should be considered as “determined” for the purposes of estimating the seismic design parameters from the code outlined below. Our site-specific ground motion hazard analysis used a VS30 of 218 m/s (714 ft/s). Please be advised if ground improvement is not implemented for the site with a planned one-, two- or three-level below-grade basement, the site and project will fall under the criteria of Site Class F and the seismic design parameters presented in Sections 7.4 through 7.6 of this report will no longer be valid. If the site cannot be classified as Soil Classification D as discussed above, our analysis will have to be revised including a site-specific response analysis (SRA) following Section 21.1 of ASCE 7-16. 7.3 CODE-BASED SEISMIC DESIGN PARAMETERS Code-based spectral acceleration parameters were determined based on mapped acceleration response parameters adjusted for the specific site conditions. Mapped Risk-Adjusted Maximum Considered Earthquake (MCER) spectral acceleration parameters (SS and S1) were determined using the ATC Hazards by Location website (https://hazards.atcouncil.org). The mapped acceleration parameters were adjusted for local site conditions based on the average soil conditions for the upper 100 feet (30 meters) of the soil profile. Code-based MCER spectral response acceleration parameters adjusted for site effects (SMS and SM1) and design spectral response acceleration parameters (SDS and SD1) are presented in Table 5. In accordance with Section 11.4.8 of ASCE 7-16, structures on Site Class D sites with mapped 1-second period spectral acceleration (S1) values greater than or equal to 0.2 require a site-

specific ground motion hazard analysis be performed in accordance with Section 21.2 of ASCE 7-16. Design seismic parameters are presented in Table 8. The values in Table 5 should not be used for design. Values summarized in Table 6 are only used to determine Seismic Design Category and comparison with minimum code requirements in our site-specific ground motion hazard analysis (Section 7.4 to follow).

*Assumed, to be confirmed by Structural Engineer **null – per Section 11.4.8 of ASCE 7-16 7.4 GROUND MOTION HAZARD ANALYSIS In accordance with Section 11.4.8 of ASCE 7-16, we performed a ground motion hazards analysis (GMHA) in accordance with Chapter 21, Section 21.2 of ASCE 7. Following the methodology outlined in Section 21.2, we evaluated both Probabilistic MCER Ground Motions in accordance with Method 1 and Deterministic MCER Ground Motions to generate our recommended design response spectrum for the project.

Page 31: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 26

We performed a GMHA in accordance with ASCE 7-16 Chapter 21.2 and 2019 CBC Section 1803.6. Our analyses were performed using the USGS interface Unified Hazard Tool (UHT) based on the UCERF 3 Data Set, Building Seismic Safety Council (BSSC) Scenario Catalog 2014 event set (BSSC 2014), and the 2014 National Seismic Hazard Maps – Source Parameters (NSHMP deterministic event set). Additionally, we utilized the USGS program Response Spectra Plotter with combined models (Combined: WUS 2014 (4.1)). Our analysis utilized the mean ground motions predicted by four of the Next Generation Attenuation West 2 (NGA-West 2) relationships: Boore-Atkinson (2013), Campbell-Bozognia (2013), Chiou-Youngs (2013), and Abrahamson-Silva (2013). Rotation factors (scale factors) were determined as specified in ASCE 7-16 Chapter 21, Section 21.2, to calculate the maximum rotated component of ground motions (ASCE, 2016). 7.4.1 Probabilistic MCER We performed a probabilistic seismic hazard analysis (PSHA) in accordance with ASCE 7-16 Section 21.2.1. The probabilistic MCE acceleration response spectrum is defined as the 5 percent damped acceleration response spectrum having a 2 percent probability of exceedance in a 50-year period (2,475-year return period). The probabilistic MCE spectrum was multiplied by Risk Coefficients (CR) to determine the probabilistic MCER. We used Risk Coefficients (CRS and CR1) of 0.957 and 0.934, respectively, based on ASCE 7-16 Section 21.2.1.1 - Method 1 and the ATC website. Risk coefficients for the various periods are presented in Table 6, Column 3. The resulting probabilistic MCER is presented on Figure 5 (red line). Spectral ordinates are tabulated in Table 6, Column 6. 7.4.2 Deterministic MCER We performed deterministic seismic hazard analyses in accordance with ASCE 7-16 Section 21.2.2 and ASCE 7-16 Supplement No. 1. The deterministic MCER acceleration response spectrum is calculated as the largest 84th percentile ground motion in the direction of maximum horizontal response for each period for characteristic earthquakes on all known active faults within the region. The largest deterministic ground motion for periods 2 seconds or less resulted from a Mw 7.58 earthquake on the Hayward Fault (RC+HN+HS+HE segments), located at a distance of approximately 10.71 km from the site and from a Mw 8.04 earthquake on the San Andreas Fault (SAO+SAN+SAP+SAS segments), located at a distance of approximately 18.94 km from the site for periods greater than 2 seconds. In accordance with Supplement No.1 of ASCE 7-16, when the largest spectral response acceleration of the resulting deterministic ground motion response spectrum is less than 1.5Fa then the largest 84th percentile rotated response spectrum (Table 6, Column 4) shall be scaled by a single factor such that the maximum response spectral acceleration equals 1.5Fa. For Site Classes A, B, C and D, Fa is determined using Table 11.4.1 with the value of Ss taken as 1.5; for Site Class E, Fa shall be taken as 1.0. When the largest spectral response acceleration of the

Page 32: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 27

probabilistic ground motion response of 21.2.1 is less than 1.2Fa, the deterministic ground motion response spectrum does not need to be calculated. As the largest probabilistic spectral response acceleration was determined to be 2.559 which is greater than 1.2Fa, where Fa is taken as 1.000 from Table 11.4-1 in ASCE 7-16 Supplement No.1, the 84th percentile rotated response spectrum was calculated as part of the deterministic analyses. The maximum spectral acceleration from the 84th percentile rotated response spectrum was then compared to 1.5Fa to determine if a scale factor needed to be applied. The deterministic MCE spectrum are tabulated in Table 6, Column 5. The deterministic MCER is presented graphically on Figure 5 (blue line). 7.4.3 Site-Specific MCER The site-specific MCER is defined by ASCE 7-16 Section 21.2.3 as the lesser of the deterministic and probabilistic MCER’s at each period. Spectral ordinates for the site-specific MCER are tabulated in Table 6, Column 7 and shown graphically on Figure 5 (dashed black line). Table 6: Development of Site-Specific MCER Spectrum

7.4.4 Design Response Spectrum The Design Response Spectrum (DRS) is defined in ASCE 7-16 Section 21.3 as two-thirds of the site-specific MCER, but not less than 80% of the general design response spectrum. Spectral accelerations corresponding to two-thirds of the MCER are tabulated in Table 7, Column 2. Ordinates corresponding to 80% of the general Site Class D response spectrum are tabulated below in Table 7, Column 3. Ordinates of the site-specific DRS are tabulated in Table 7, Column 4.

7.5 DESIGN ACCELERATION PARAMETERS Design acceleration parameters (SDS and SD1) were determined in accordance with Section 21.4 of ASCE 7-16. SDS is defined as the design spectral acceleration at 90% of the maximum spectral acceleration, Sa, obtained from the site-specific spectrum, at any period within the range from 0.2 to 5 seconds, inclusive. SD1 is defined as the maximum value of the product, TSa, for periods from 1 to 2 seconds for sites with vs,30 > 1,200 ft/s (vs,30 > 365.76 m/s) and for periods from 1 to 5 seconds for sites with vs,30 ≤ 1,200 ft/s (vs,30 ≤365.76 m/s).

Page 34: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 29

Site-specific MCER spectral response acceleration parameters (SMS and SM1) are calculated as 1.5 times the SDS and SD1 values, respectively, but not less than 80% of the code-based values presented in Table 5. Site-specific design acceleration parameters are summarized in Table 8. When using the Equivalent Lateral Force Procedure, ASCE 7-16 Section 21.4 allows using the spectral acceleration at any period (T) in lieu of SD1/T in Eq. 12.8-3 and SD1TL/T2 in Eq. 12.8-4. The site-specific spectral acceleration at any period may be calculated by interpolation of the spectral ordinates in Table 7, Column 4. Table 8: Site-Specific Design Acceleration Parameters

7.6 SITE-SPECIFIC MCEG PEAK GROUND ACCELERATION We calculated the Site-Specific MCEG Peak Ground Acceleration (PGAM) in accordance with ASCE 7-16 Section 21.5. The Site-Specific PGAM is calculated as the lesser of probabilistic and deterministic geometric mean PGA. The 2% in 50-year probabilistic geometric mean PGA is 0.907g. The deterministic PGA is considered the greater of the largest 84th percentile deterministic geometric mean PGA (0.703g) or one-half of the tabulated FPGA value from ASCE 7-16 Table 11.8.1 with the value of PGA taken as 0.5g. For Site Class D, FPGA is 1.100 and one-half of the FPGA is 0.55g; therefore, the deterministic PGA is 0.703g. Additionally, the Site-Specific PGAM may not be less than 80% of the mapped PGAM determined from ASCE 7-16 Equation 11.8-1. The mapped PGAM for the site is 0.607g; 80% of PGAM is 0.486g. Therefore, the Site-Specific PGAM for the site is 0.703g. We note that if ground improvement is not implemented, that the seismic design parameters presented in this report will have to be revised to include a site response analysis (SRA) following Section 21.1 of ASCE 7-16. SECTION 8: FOUNDATIONS 8.1 SUMMARY OF RECOMMENDATIONS In our opinion, due to the high anticipated foundation loads, and significant anticipated static and seismic settlements, the proposed structure may be supported on a reinforced concrete mat foundation over ground improvement. As an alternative to ground improvement, the structure may also be supported by a deep foundation system such as auger-cast piles. If ground improvement is selected, we recommend a design-build ground improvement contractor design

the mitigation using an appropriate ground improvement technique to meet the project requirements and recommendations provided herein. 8.2 REINFORCED CONCRETE MAT FOUNDATION OVER GROUND IMPROVEMENT As discussed, to minimize potentially high static and seismic total and differential settlements based on the preliminary assumed loads, the structure may be supported on a reinforced concrete mat foundation overlying ground improvement. Ground improvement should be designed to provide adequate bearing capacity and reduce total settlement due to static and seismic conditions to tolerable levels as described below. Additional ground improvement recommendations are provided in the following sections. On a preliminary basis and for your project forward planning, we anticipate Drill Displacement ColumnTM (DDC) ground improvement or other similar ground densification elements could be utilized to manage settlement under a mat foundation. We estimate DDC column spacing on the order of 4 to 5 feet on-center (square layout) with allowable capacities on the order of 50 to 70 kips each. The above DDC ground improvement element is based on estimated depths of 30 to 40 feet below the mat foundation. The improved bearing pressures are estimated to be on the order of 4,000 to 5,000 psf. The above estimates are preliminary, and during design the design-build ground improvement contractor should collaborate with the structural engineer for the mat design. 8.2.1 Settlement Ground improvement should be designed to reduce total settlement due to static and seismic conditions to tolerable levels. As discussed in the “Ground Improvement” section below, the ground improvement design should be such that the total foundation settlement (static and seismic) is reduced to about 2½ inches, or less, from the center of the mat to an edge with no more than about 1½ inches for either the static or seismic components. 8.2.2 Mat Modulus of Soil Subgrade Reaction The modulus of soil subgrade reaction is a model element that represents the response to a specific loading condition, including the magnitude, rate, and shape of loading, given the subsurface conditions at that location. We recommend using a variable modulus of soil subgrade reaction to provide a more accurate soil response and prediction of shears and moments in the mat. This will require at least one iteration between our soil model and the structural SAFE (or similar) analysis for the mat. As the mat foundation will be underlain by ground improvement, the modulus of subgrade reaction will be affected by the ground improvement method and the bearing pressure across the mat. Once ground improvement design has been confirmed and initial bearing pressures determined, please forward a color plot of contact pressures for the mat (to scale) so that we can provide a revised plan with updated contours of equal modulus of soil subgrade reaction values. An initial soil subgrade modulus of 10 pci can be used for the initial analysis until additional design details are confirmed.

PROJECT WEST JULIAN 1178-2-2

Page 31

8.2.3 Lateral Loading Lateral loads may be resisted by friction between the bottom of mat foundation and the supporting subgrade, and also by passive pressures generated against deepened mat edges. An ultimate frictional resistance of 0.4 applied to the mat dead load, and an ultimate passive pressure based on an equivalent fluid pressure of 400 pcf may be used in design. The structural engineer should apply an appropriate factor of safety (such as 1.5) to the ultimate values above. The upper 12 inches of soil should be neglected when determining passive pressure capacity. 8.2.4 Mat Foundation Construction Considerations Prior to placement of any vapor retarder and mat construction, the subgrade should be proof-rolled and visually observed by a Cornerstone representative to confirm stable subgrade conditions. The pad moisture should also be checked at least 24 hours prior to vapor barrier or mat reinforcement placement to confirm that the soil has a moisture content of at least 2 percent over optimum in the upper 12 inches. 8.3 GROUND IMPROVEMENT 8.3.1 Ground Improvement Requirements As discussed above, mat foundations may be used in combination with ground improvement to improve bearing capacities of the soils beneath the structure as well as reduce the total differential settlements (seismic and static) to tolerable levels. Ground improvement should be designed to increase the soils bearing capacities and improve the subsurface soils such that the combined static and seismic settlement is reduced to 2½ inches or less, and no more than 1½ inches for either the static or seismic component, enabling the structure to be supported on a mat foundation if determined feasible. Ground improvement should provide adequate confining improvement around all foundations. We anticipate that the ground improvement construction will be a design-build process where Cornerstone Earth Group will review preliminary design-build ground improvement designs, including proposed spacing and layout relative to the foundation plans and installation lengths, and anticipated bearing capacity and densification improvement of the surrounding soils prepared by prospective contractors, provide comments, and come to a general agreement with the contractor on the intended design approach. Ground improvement should consist of densification techniques to improve the ground’s resistance to liquefaction, reduce static settlement, and improve bearing capacity and seismic performance. Ground densification techniques could potentially consist of Drill Displacement ColumnTM (DDC), grouted displacement columns (i.e. CLSM), or similar densification techniques. Granular densification ground improvement elements may not be desired as they may pose an issue for a dewatering system. The intent of the ground improvement design would be to increase the bearing capacity of the underlying soils, increase the density of the potentially liquefiable layers, and increase the density of the compressible clays to help reduce post-construction consolidation settlements. The degree to which the density is increased will depend on the improvement method, spacing, and depth.

Page 37: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 32

Based on the chosen ground improvement technique, the upper 1 to 2 feet or more of the working pad will likely need to be re-compacted after ground improvement installation, due to surface disturbance and potential ground heave. For this reason, we do not recommend preparation of the final pad, placement of non-expansive fill, or the construction of utilities prior to ground improvement. Contractors to perform recommended ground improvement should have adequate experience for the proposed methods to address the requirements herein. All construction quality control and quality assurance records should be supplied to the design team for review on completion of the ground improvement. Adequate quality control readings must be available at the time of installation so that real time oversight can be provided. The instrumentation provided will depend on the ground improvement method chosen. Once a method is chosen, the geotechnical engineer should modify the project design guideline specification for the appropriate method. We recommend that the ground improvement design include, but not be limited to: 1) drawings showing the ground improvement layout, spacing and diameter, 2) the foundation layout plan, 3) proposed ground improvement length, 4) top and bottom elevations. We should be retained to review the ground improvement contractor’s plan and settlement estimates prior to construction, and to review and confirm that the contractor’s ground improvement design will satisfactorily meet the design criteria based on the performance testing. Following the completion of the Ground Improvement Performance Testing indicated below, a final ground improvement design report and calculation package, including support for the ground improvement design and indicating that the design criteria will be met, should be submitted to the design team for review and approval. 8.3.2 Ground Improvement Performance Testing Performance testing typically consists of a pre-construction test section with post-installation load testing and CPT testing to confirm that the necessary soil strength and densification increases were achieved to meet the bearing capacity and settlement criteria. We should observe and monitor installation of the test arrays and production ground improvement on a full-time basis and review the post-test array settlement analyses provided by the contractor. Working with the structural engineer, the team will evaluate whether differential settlement estimates and bearing capacities are tolerable and adequate or whether additional ground improvement is required. The proposed design capacity of the ground improvement will be confirmed prior to construction by the installation of at least two test array sections of four ground improvement columns with installation lengths and spacing as initially agreed to between the ground improvement contractor and Cornerstone Earth Group. Testing of arrays should include CPT testing at center of array, sampling for strength consolidation testing, and a modulus test of at least one pier in each test array. To validate the parameters selected for a specific project, a modulus load test is performed on a test pier typically constructed in locations chosen in coordination with the geotechnical engineer. Modulus tests are conducted to a pressure equal to at least 150% of the maximum design top of pier stress to assure a reasonable level of safety which supports long

Page 33

term settlement control and demonstrates that the ground improvement element has adequate strength. Performing modulus testing beyond the limit state top of pier stress meets the intent of the building code with respect to shallow foundation support. Modulus testing should be performed in general accordance with ASTM D1143. The ground improvement contractor shall make their own interpretation of strength parameters and other characteristics for the soil, obtained or derived from the soil boring logs, cone penetration tests, and any geotechnical laboratory testing data provided in the Geotechnical Report and these specifications for bearing capacity analysis. Static settlement shall be assessed using appropriate soil parameters for an elastic settlement analysis based on an area replacement ratio considering the stiffness of the native soils, and the densification columns. Liquefaction and seismic settlement estimates shall be performed using the methodology presented in the project geotechnical report, which followed the procedures in the 2008 monograph, Soil Liquefaction During Earthquakes (Idriss and Boulanger, 2008). Liquefaction and settlement shall be evaluated for the upper 50 feet of the soil profile. Any additional subsurface information needed to design the ground improvement shall be the responsibility of the Contractor. 8.4 ALTERNATIVE FOUNDATION 8.4.1 Deep Foundations As an alternative to a mat foundation over ground improvements or if the estimated settlements exceed the structural requirements, the structure can also be supported on deep foundations. The proposed office tower could be supported on conventional drilled, cast-in-place augercast (ACIP) piles. Conventional augercast piles have been successfully used for projects in downtown San Jose and around the Bay Area in similar soil conditions. ACIP piles are concrete piles that are cast in place using a hollow-stem auger that drills to the design depth and then sand-cement grout (4,000 to 6,000 psi grout) is pumped through the hollow-stem as the drill stem is extracted. Two types of augercast piles are typically available: ACIP piles, which like piers, remove the soil column and replace it with grout; and APGD piles, which displace the soil column as the drill stem is advanced, similar to driven piles, prior to pumping the grout. Because of the presence of several dense sand layers across the site, displacement (APGD) piles are not recommended. Augercast piles are a low noise and vibration installation compared to driven piles. Various types of steel reinforcing including rebar cages or H-piles may be installed into the still-wet grout after drilling to satisfy bending moment requirements. On a preliminary basis, we estimate a typical 100-ton pile (vertical capacity), 16-inch and 18-inch auger-cast piles would be about 60 to 75 feet in length. If this alternative is considered, we can provide additional recommendations. 8.5 HYDROSTATIC UPLIFT AND WATERPROOFING As previously discussed, we recommend a design groundwater level of 10 feet below the existing grade. This will result in significant uplift pressures at the bottom of the mat foundation. It is possible that the design will require uplift anchors for permanent resistance of the

Page 39: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 34

pressures. A buoyancy evaluation should be performed by the structural engineer to evaluate the number of anchors that would be needed, if any. The bottom of the mat foundation and the full height of the garage walls should be fully waterproofed, with the design performed by a waterproofing consultant. 8.6 UPLIFT GROUND ANCHORS As previously mentioned, uplift anchors may be needed to resist significant uplift pressures at the bottom of the mat foundation. The following presents ultimate uplift capacities. The structural engineer should apply an appropriate factor of safety to the ultimate values. The following values may be increased by approximately a factor of 5 for post-grouted anchors with pressures exceeding about 150 psi based on information in Section 5.9 of FHWA’s Geotechnical Engineering Circular No. 4 (1999), “Ground Anchors and Anchored Systems.” All anchors should be load tested to confirm design capacity in accordance with FHWA recommendations. Ground anchors should be spaced horizontally at a minimum of 3 diameters apart. Construction tolerances for vertical alignment should be specified such that there will not be overlap at the anchor tips. Table 9: Recommended Ground Anchor Ultimate Capacities

We recommend a ground anchor design-build contractor be retained to confirm the information provided and for additional recommendations, as required. SECTION 9: SLABS-ON-GRADES AND PEDESTRIAN PAVEMENTS 9.1 GARAGE RAMP SLABS-ON-GRADE Slabs-on-grade for garage ramps should be at least 5 inches thick and if constructed with minimal reinforcement intended for shrinkage control only, should have a minimum compressive strength of 3,000 psi. If the slab will have heavier reinforcing because the slab will also serve as a structural diaphragm, the compressive strength may be reduced at the structural engineer’s discretion. The garage slab should also be supported on at least 6 inches of either Class 2 aggregate base or ¾-inch clean, crushed rock placed and compacted in accordance with the “Compaction” section of this report. Consideration should be given to limiting the control joint spacing to a maximum of about 2 feet in each direction for each inch of concrete thickness.

9.2 EXTERIOR FLATWORK Exterior concrete flatwork subject to pedestrian loading should be at least 4 inches thick and supported on at least 4 inches of Class 2 aggregate base overlying subgrade prepared in accordance with the “Earthwork” recommendations of this report. Flatwork that will be subject to heavier or frequent vehicular loading should be designed in accordance with the recommendations in the “Vehicular Pavements” section below. To help reduce the potential for uncontrolled shrinkage cracking, adequate expansion and control joints should be included. Consideration should be given to limiting the control joint spacing to a maximum of about 2 feet in each direction for each inch of concrete thickness. Flatwork should be isolated from adjacent foundations or retaining walls except where limited sections of structural slabs are included to help span irregularities in retaining wall backfill at the transitions between at-grade and on-structure flatwork. SECTION 10: VEHICULAR PAVEMENTS 10.1 ASPHALT CONCRETE The following asphalt concrete pavement recommendations tabulated below are based on the Procedure 608 of the Caltrans Highway Design Manual, estimated traffic indices for various pavement-loading conditions, and on an assumed R-value of 5. The design R-value was chosen based on engineering judgment considering the possibly variable surface conditions. Table 10: Asphalt Concrete Pavement Recommendations, Design R-value = 5

*Caltrans Class 2 aggregate base; minimum R-value of 78 Frequently, the full asphalt concrete section is not constructed prior to construction traffic loading. This can result in significant loss of asphalt concrete layer life, rutting, or other pavement failures. To improve the pavement life and reduce the potential for pavement distress through construction, we recommend the full design asphalt concrete section be constructed prior to construction traffic loading. Alternatively, a higher traffic index may be chosen for the areas where construction traffic will be using the pavements.

10.2 PORTLAND CEMENT CONCRETE The exterior Portland Cement Concrete (PCC) pavement recommendations tabulated below are based on methods presented in the Portland Cement Association (PCA) design manual (PCA, 1984). Recommendations for garage slabs-on-grade were provided in the “Concrete Slabs and Pedestrian Pavements” section above. We have provided a few pavement alternatives as an anticipated Average Daily Truck Traffic (ADTT) was not provided. An allowable ADTT should be chosen that is greater than what is expected for the development. Table 11: PCC Pavement Recommendations, Design R-value = 5

Allowable ADTT

Minimum PCC Thickness (inches)

13 5½ 130 6

The PCC thicknesses above are based on a concrete compressive strength of at least 3,500 psi, supporting the PCC on at least 6 inches of Class 2 aggregate base compacted as recommended in the “Earthwork” section, and laterally restraining the PCC with curbs or concrete shoulders. Adequate expansion and control joints should be included. Consideration should be given to limiting the control joint spacing to a maximum of about 2 feet in each direction for each inch of concrete thickness. 10.2.1 Stress Pads for Trash Enclosures Pads where trash containers will be stored, and where garbage trucks will park while emptying trash containers, should be constructed on Portland Cement Concrete. We recommend that the trash enclosure pads and stress (landing) pads where garbage trucks will store, pick up, and empty trash be increased to a minimum PCC thickness of 7 inches. The compressive strength, underlayment, and construction details should be consistent with the above recommendations for PCC pavements. SECTION 11: SITE RETAINING WALLS 11.1 STATIC LATERAL EARTH PRESSURES The structural design of any site retaining wall should include resistance to lateral earth pressures that develop from the soil behind the wall, any undrained water pressure, and surcharge loads acting behind the wall. Provided a drainage system is constructed behind the wall to prevent the build-up of hydrostatic pressures as discussed in the section below, we recommend that the walls with level backfill be designed for the following pressures:

Page 42: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 37

Table 12: Recommended Lateral Earth Pressures

Wall Condition Lateral Earth Pressure* Additional Surcharge Loads Unrestrained – Cantilever Wall 45 pcf ⅓ of vertical loads at top of wall

Restrained – Braced Wall 45 pcf + 8H** psf ½ of vertical loads at top of wall * Lateral earth pressures are based on an equivalent fluid pressure for level backfill conditions ** H is the distance in feet between the bottom of footing and top of retained soil Basement walls should be designed as restrained walls. If adequate drainage cannot be provided behind the wall, an additional equivalent fluid pressure of 40 pcf should be added to the values above for both restrained and unrestrained walls for the portion of the wall that will not have drainage. The portion of the below-grade parking structure extending below the design groundwater depth of 10 feet should be designed with the additional 40 pcf. If desired the upper portion of the below-grade parking structure, above the design groundwater, may be designed as drained provided an outlet or sump can collect the water. A drainage mat should not be used below the design groundwater depth. Damp proofing or waterproofing of the walls may be considered where moisture penetration and/or efflorescence are not desired. 11.2 SEISMIC LATERAL EARTH PRESSURES The 2019 California Building Code (CBC) states that lateral pressures from earthquakes should be considered in the design of basements and retaining walls. We developed seismic earth pressures for the proposed basement using interim recommendations generally based on refinement of the Mononobe-Okabe method (Lew et al., SEAOC 2010). Because the walls are greater than 12 feet in height, and peak ground accelerations are greater than 0.40g, we checked the result of the total seismic increment when added to the recommended active earth pressure against the recommended fixed (restrained) wall earth pressures. Basement walls are not free to deflect, and should therefore be designed for static conditions as a restrained wall, which is also a CBC requirement. For one level-below grade parking garage the wall is restrained, or will act as a restrained wall, and will be designed for 45 pcf (equivalent fluid pressure) plus a uniform earth pressure of 8H psf, based on current recommendations for seismic earth pressures, it appears that active earth pressures plus a seismic increment do not exceed the fixed wall earth pressures. Therefore, an additional seismic increment above the design earth pressures is not required as long as the walls are designed for the restrained wall earth pressures recommended above in accordance with the CBC. Based on current recommendations for seismic earth pressures, it appears that active earth pressures plus a seismic increment exceed the restrained (i.e. at-rest), static wall earth pressures for a two- or three-level below grade parking garage. Therefore, we recommend checking the walls for the seismic condition in accordance with the interim recommendations of the above referenced paper and the 2016 CBC.

Page 43: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 38

The CBC prescribes basic load combinations for structures, components and foundations with the intention that their design strength equals or exceeds the effects of the factored loads. With respect to the load from lateral earth pressure and groundwater pressure, the CBC prescribes the basic combinations shown in CBC equations 16-2 and 16-7 below. 1.2(D + F) + 1.6(L + H) + 0.5(Lr or S or R) [Eq. 16-2] In Eq. 16-2: H - should represent the total static lateral earth pressure, which for the basement wall will be restrained (use 45 pcf + 8H psf) 0.9(D + F) + 1.0E + 1.6H [Eq. 16-7] In Eq. 16-7: H - should represent the static “active” earth pressure component under seismic loading

conditions (use 45 pcf)

E - should represent the seismic increment component in Eq. 16-7, a triangular load with a resultant force of 7H2, which should be applied one third of the height up from the base of the wall (and which can also be expressed as an equivalent fluid pressure equal to 14 pcf).

The interim recommendations in the SEAOC paper more appropriately split out "active" earth pressure (and not the restrained ["at-rest"] pressure) from our report and provide the total seismic increment so that different load factors can be applied in accordance with different risk levels. 11.3 WALL DRAINAGE 11.3.1 At-Grade Site Walls Adequate drainage should be provided by a subdrain system behind all walls. This system should consist of a 4-inch minimum diameter perforated pipe placed near the base of the wall (perforations placed downward). The pipe should be bedded and backfilled with Class 2 Permeable Material per Caltrans Standard Specifications, latest edition. The permeable backfill should extend at least 12 inches out from the wall and to within 2 feet of outside finished grade. Alternatively, ½-inch to ¾-inch crushed rock may be used in place of the Class 2 Permeable Material provided the crushed rock and pipe are enclosed in filter fabric, such as Mirafi 140N or approved equivalent. The upper 2 feet of wall backfill should consist of compacted on-site soil. The subdrain outlet should be connected to a free-draining outlet or sump. Miradrain, Geotech Drainage Panels, or equivalent drainage matting can be used for wall drainage as an alternative to the Class 2 Permeable Material or drain rock backfill. Horizontal strip drains connecting to the vertical drainage matting may be used in lieu of the perforated pipe and crushed rock section. The vertical drainage panel should be connected to the perforated pipe or horizontal drainage strip at the base of the wall, or to some other closed or through-wall system such as the TotalDrain system from AmerDrain. Sections of horizontal drainage strips should be connected with either the manufacturer’s connector pieces or by pulling back the filter fabric, overlapping the panel dimples, and replacing the filter fabric over

Page 44: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 39

the connection. At corners, a corner guard, corner connection insert, or a section of crushed rock covered with filter fabric must be used to maintain the drainage path. Drainage panels should terminate 18 to 24 inches from final exterior grade. The Miradrain panel filter fabric should be extended over the top of and behind the panel to protect it from intrusion of the adjacent soil. 11.3.2 Below-Grade Walls Miradrain, AmerDrain or other equivalent drainage matting should be used for wall drainage where below-grade walls are temporarily shored and the shoring will be flush with the back of the permanent walls. The drainage panel should be connected at the base of the wall by a horizontal drainage strip and closed or through-wall system such as the TotalDrain system from AmerDrain. Sections of horizontal drainage strips should be connected with either the manufacturer’s connector pieces or by pulling back the filter fabric, overlapping the panel dimples, and replacing the filter fabric over the connection. At corners, a corner guard, corner connection insert, or a section of crushed rock covered with filter fabric must be used to maintain the drainage path. Drainage panels should terminate 18 to 24 inches from final exterior grade unless capped by hardscape. The drainage panel filter fabric should be extended over the top of and behind the panel to protect it from intrusion of the adjacent soil. If the shoring system will be offset behind the back of permanent wall, the drainage systems discussed in the “At-Grade Site Walls” section may also be used. 11.4 BACKFILL Where surface improvements will be located over the retaining wall backfill, backfill placed behind the walls should be compacted to at least 95 percent relative compaction using light compaction equipment. Where no surface improvements are planned, backfill should be compacted to at least 90 percent. If heavy compaction equipment is used, the walls should be temporarily braced. As discussed previously, consideration should be given to the transitions from on-grade to on-structure. Providing subslabs or other methods for reducing differential movement of flatwork or pavements across this transition should be included in the project design. 11.5 FOUNDATIONS We anticipate that the walls of the below-grade parking structure will be supported on the mat foundation over ground improvement as mentioned above. At-grade retaining walls may be supported on conventional shallow foundations designed in accordance with the following recommendations. Continuous footings should be at least 15 inches wide, and extend at least 15 inches below the lowest adjacent grade.

Page 45: Type of Services Geotechnical Investigation San Jose

PROJECT WEST JULIAN 1178-2-2

Page 40

Footings constructed to the above dimensions and in accordance with the “Earthwork” recommendations of this report should be design using a low bearing pressure to limit total settlement. We recommend a maximum allowable bearing pressure of 2,500 psf. This pressure is a net value; the weight of the footing may be neglected for the portion of the footing extending below grade (typically, the full footing depth). Top and bottom mats of reinforcing steel should be included in continuous footings to help span irregularities and differential settlement. Lateral loads may be resisted by friction between the bottom of footing and the supporting subgrade, and also by passive pressures generated against footing sidewalls. An ultimate frictional resistance of 0.45 applied to the footing dead load, and an ultimate passive pressure based on an equivalent fluid pressure of 450 pcf may be used in design. The structural engineer should apply an appropriate factor of safety (such as 1.5) to the ultimate values above. Where footings are adjacent to landscape areas without hardscape, the upper 12 inches of soil should be neglected when determining passive pressure capacity.

APPENDIX A: PREVIOUS FIELD INVESTIGATION The field investigation consisted of a surface reconnaissance and a subsurface exploration program using 20-ton truck-mounted Cone Penetration Test equipment and truck-mounted, hollow-stem auger drilling equipment. Three CPT soundings were also performed in accordance with ASTM D 5778-95 (revised, 2002) on August 28, 2017, to depths ranging from approximately 75 to 110 feet. Two 8-inch-diameter exploratory borings were drilled on September 1, 2017 to depths of 69½ and 119½ feet. The approximate locations of exploratory borings and CPTs are shown on the Site Plan, Figure 2. The soils encountered were continuously logged in the field by our representative and described in accordance with the Unified Soil Classification System (ASTM D2488). Boring logs, as well as a key to the classification of the soil and bedrock, are included as part of this appendix. Boring and CPT locations were approximated using existing site boundaries and other site features as references. Boring and CPT elevations were not determined. The locations of the borings and CPTs should be considered accurate only to the degree implied by the method used. Representative soil samples were obtained from the borings at selected depths. All samples were returned to our laboratory for evaluation and appropriate testing. The standard penetration resistance blow counts were obtained by dropping a 140-pound hammer through a 30-inch free fall. The 2-inch O.D. split-spoon sampler was driven 18 inches and the number of blows was recorded for each 6 inches of penetration (ASTM D1586). 2.5-inch I.D. samples were obtained using a Modified California Sampler driven into the soil with the 140-pound hammer previously described. Relatively undisturbed samples were also obtained with 2.875-inch I.D. Shelby Tube sampler which were hydraulically pushed. Unless otherwise indicated, the blows per foot recorded on the boring log represent the accumulated number of blows required to drive the last 12 inches. The various samplers are denoted at the appropriate depth on the boring logs. The CPT involved advancing an instrumented cone-tipped probe into the ground while simultaneously recording the resistance at the cone tip (qc) and along the friction sleeve (fs) at approximately 5-centimeter intervals. Based on the tip resistance and tip to sleeve ratio (Rf), the CPT classified the soil behavior type and estimated engineering properties of the soil, such as equivalent Standard Penetration Test (SPT) blow count, internal friction angle within sand layers, and undrained shear strength in silts and clays. A pressure transducer behind the tip of the CPT cone measured pore water pressure (u2). Graphical logs of the CPT data is included as part of this appendix. Field tests included an evaluation of the unconfined compressive strength of the soil samples using a pocket penetrometer device. The results of these tests are presented on the individual boring logs at the appropriate sample depths. Attached boring and CPT logs and related information depict subsurface conditions at the locations indicated and on the date designated on the logs. Subsurface conditions at other locations may differ from conditions occurring at these boring and CPT locations. The passage of time may result in altered subsurface conditions due to environmental changes. In addition,

any stratification lines on the logs represent the approximate boundary between soil types and the transition may be gradual.

APPENDIX B: PREVIOUS LABORATORY TEST PROGRAM The laboratory testing program was performed to evaluate the physical and mechanical properties of the soils retrieved from the site to aid in verifying soil classification. Moisture Content: The natural water content was determined (ASTM D2216) on 21 samples of the materials recovered from the borings. These water contents are recorded on the boring logs at the appropriate sample depths. Dry Densities: In place dry density determinations (ASTM D2937) were performed on 19 samples to measure the unit weight of the subsurface soils. Results of these tests are shown on the boring logs at the appropriate sample depths. Washed Sieve Analyses: The percent soil fraction passing the No. 200 sieve (ASTM D1140) was determined on four samples of the subsurface soils to aid in the classification of these soils. Results of these tests are shown on the boring logs at the appropriate sample depths. Plasticity Index: One Plasticity Index determination (ASTM D4318) was performed on a sample of the subsurface soil to measure the range of water contents over which this material exhibits plasticity. The Plasticity Index was used to classify the soil in accordance with the Unified Soil Classification System and to evaluate the soil expansion potential. Results of this test are shown on the boring log at the appropriate sample depth. Undrained-Unconsolidated Triaxial Shear Strength: The undrained shear strength was determined on two relatively undisturbed sample(s) by unconsolidated-undrained triaxial shear strength testing (ASTM D2850). The results of this test are included as part of this appendix. Consolidation: Three consolidation tests (ASTM D2435) were performed on relatively undisturbed samples of the subsurface clayey soils to assist in evaluating the compressibility property of this soil. Results of the consolidation tests are presented graphically in this appendix.
