3. PROJECT BACKGROUND AND DESCRIPTION Plaza Mexico is a large retail center located in Lynwood that has become a hub for Mexican American culture in Southern California. Plaza Mexico Residences is intended to be the first phase of Plaza Mexico’s expansion plan. The development is located directly adjacent to the west of the existing Plaza Mexico. The Plaza Mexico Residences site is rectangular in shape, about 680 feet long by 230 feet wide, approximately 3.5 acres in footprint and was formerly occupied by a large warehouse building that was demolished some time in 2006 – 2007 period. The site is essentially level with no pronounced elevation changes. Plaza Mexico Residences will be a mixed-use residential development featuring over 550 residential units. The proposed development currently considers a 7-story parking structure including one partial subterranean level located in the center portion of the site, flanked by two 5-story residential to the east and the west. This conceptual layout is shown in Diagram 1. It is understood that the subgrade soils at the site have been contaminated and that some remediation was recently carried. At this point the extent of the remaining contamination is not known but it is expected that grading of the site is likely encounter contaminated materials. Because the precise determination of the contamination extent is not known and to minimize the associated mitigation cost risk and because of adverse geotechnical conditions encountered at the site as described in this report a preference is given to a deep foundation system over the more conventional grading and shallow foundation system. Therefore, it is anticipated that deep pile foundations will be used to support the residential buildings and the parking structure and also support a structural floor slab. It is estimated that the building columns will be spaced on about a 30 feet by 30 feet grid with column loads of approximately 550 kips.

4. SUBSURFACE EXPLORATIONS The current subsurface soil and groundwater conditions beneath the site were explored by Tetra Tech on September 16 and 19, and October 25 and 26, 2016 and included the drilling, logging, and sampling of 8 hollow stem auger soil exploratory borings identified as B-104 through B-111 to a maximum depth of 66.5 feet,. In addition, on October 25, 2016, 4 Cone Penetration Tests (CPTs) identified as C-101 to C-104 were advanced to a maximum depth of 79 feet. Prior to starting the field exploration program, a field reconnaissance was conducted to observe the site conditions and to mark the locations of the planned boreholes and CPTs. A drilling permit was obtained from the Los Angeles County Department of Public Health (LACDPH) for all the subsurface explorations. Underground Service Alert, the LACDPH inspector, and City of Lynwood personnel were also notified of the drilling schedule at least 48 hours prior to drilling. The hollow stem auger borings were excavated using a CME-75 truck-mounted drill rig equipped with an 8-inch diameter auger and advanced to a maximum depth of approximately 66.5 feet. CPTs were advanced to a maximum depth of approximately 79 feet using a standard electronic piezocone with a 15 cm2 area and a 60-degree apex angle pushed utilizing a 30-ton truck. The approximate coordinates of the soil exploration locations, elevations, and depths are included in Table 1. The approximate soil boring and CPT locations are shown on Figure 2 – Project Layout, Boring and CPT Location Map. Bulk, driven ring-type, and small bag samples were retrieved at selected depths during drilling of the exploratory borings. Standard Penetration Testing (SPT) was performed using an SPT sampler driven by an automatic 140-pound hammer with a drop of 30 inches in general accordance with ASTM D1586. Ring-type samples were collected utilizing a California-type sampler driven by the same equipment used for the SPTs. Sampling was carried out at 2.5-foot intervals at all the borings between the depths of 2.5 and 15 feet. Otherwise sampling was carried out at 5-foot intervals. Air monitoring was conducted during the drilling phase in the southern parcel using a Photo-Ionization Detector (PID) to measure concentrations of Volatile Organic Compounds (VOCs). The soil borings were surface-logged by a California Professional Geologist in general accordance with the visual-manual procedure for description and identification of soils, ASTM D2488. The Geologist prepared the recovered samples for subsequent reference and laboratory testing. The soil boring logs are presented in Appendix A. CPT testing was carried out in accordance with ASTM D5778. The piezocone was pushed at a rate of 2 cm/sec and the soil tip resistance, soil-sleeve friction, and immediate dynamic pore water pressure response were recorded at 1-inch intervals. A copy of the Cone Penetration Test Data report is included in Appendix B. At the completion of drilling, the borings and the CPTs were backfilled with a cement-bentonite grout in accordance with LACDPH requirements. The exploratory boreholes and CPTs advanced through paved surfaces were capped with a cold asphalt patch. Soil cuttings from the borehole explorations were stored in steel drums, tested, and disposed of at an appropriate facility.

6. SUBSURFACE CONDITIONS 6.1. Regional Geology The subject site is located in the southwestern coastal plain of the greater Los Angeles Basin. The Los Angeles Basin is located within Peninsular Ranges geomorphic province which is characterized as a low-lying plain that rises gently inland to the surrounding mountains and hills including the Santa Monica and San Gabriel Mountains to the north, Puente Hills to the northeast, the Santa Ana Mountains to the Southeast, and the San Joaquin hills and Palos Verdes Peninsula to the south. The Peninsular Range is characterized by northwest-southeast trending structural blocks separated by northwest-southeast trending strike-slip faults. Within the Los Angeles Basin there are 4 structural blocks: the southwestern block, the northwestern block, the central block, and the northeastern block (Norris and Webb, 1990). The subject site is located in the Central Block, which is bounded by the Newport Inglewood- Rose Canyon fault zone to the southwest and the Whittier Elsinore fault zone to the northeast. The Los Angeles Basin is approximately 50 miles long and 30 miles wide. The Basin contains approximately 33,000 feet of marine and continental deposits of Miocene to early Pleistocene age sediments. These rocks are overlain by unconsolidated and semi-consolidated Quaternary marine and continental sediments (see Figure 3 – Geology Map). The marine and continental sediments all rest on Mesozoic schist and granitoid basement complex. 6.2. Site Geology A geologic map of the site area is shown in Figure 3. The subject site is located within the historical flood plain of the Los Angeles River. The low-lying Rosecrans Hills lie west of the site and resulted from uplift along the Newport- Inglewood Fault. According to the USGS Geologic Map of the Long Beach 30’ x 60’ Quadrangle, the site is underlain by silty and sandy Young Alluvial Fan Deposits (Qyf, – refer to Figure 3). The young alluvium was deposited by the ancestral Los Angeles River, and consists of unconsolidated layers and lenses of sand, silty sand, silts and clay. Based upon the findings from our subsurface investigation, the project site is mantled by artificial man-made fill soils. Beneath the fill, younger native alluvial soils were encountered to the base of the exploration at a maximum depth of approximately 66.5 feet in the boreholes. Generalized descriptions of the encountered units are provided below. Detailed descriptions of the encountered soil conditions in the boreholes are presented on the boring logs in Appendix A. Detailed descriptions of the encountered soil conditions in the CPTs are presented on the CPT logs in Appendix B. 6.2.1. Artificial Fill Artificial fill soils were encountered in all borings to depths ranging from approximately 6.5 to 12 feet across the entire subject site. The artificial fill soils were typically composed of soft to very stiff, gray brown to dark brown fat clay, lean clay, silt and elastic silt and, light gray to brown loose to dense, silty sand, containing traces of roots, wood fragments, gravel and brick fragments.

6.2.2. Native Alluvium Native Young Alluvial Fan deposits were encountered below the fill soils. They consisted predominately of soft to hard silts, and firm to very stiff lean and fat clays interspersed with layers of loose to dense silty sand, and medium dense to dense poorly and well graded sands extending to the maximum explored depth of 66.5 feet. Detailed descriptions of the soil conditions encountered in the borings are presented in the boring logs in Appendix A. Uncorrected SPT blowcounts in the native alluvium for the fine-grained (clayey and silty) soils generally varied from 4 to 19 indicating firm to very stiff consistency. Uncorrected SPT blowcounts in the native alluvial coarse-grained (sandy) soils generally varied from 6 to greater than 50 indicating loose to very dense materials. Detailed descriptions of the soil conditions encountered in the borings are presented on the boring logs in Appendix A. 6.3. Groundwater According to the State of California (CDMG, 1998), the historic high groundwater level near the site has been mapped at a depth of about 8 feet (Figure 4 – Historic High Groundwater Map). Groundwater was encountered in the Tetra Tech exploratory borings at a depth ranging between approximately 32 and 45 feet. A review of the database from the Los Angeles County Department of Public Works (LACDPW) for nearby wells (http://dpw.lacounty.gov/general/wells/) and Geotracker database is summarized in Table 2.

Based on the assessment of the local stratigraphy and local topography, it is our opinion that the LACDPW and Geotracker wells can be utilized for interpretation of the project groundwater conditions. Therefore, it is our conclusion that the groundwater at the site has been at minimum depth of 14.5 feet in 1931 and within 22 feet in the last 10 years. Fluctuations of the groundwater level, localized zones of perched water, and increased soil moisture content should be anticipated during and following the rainy season. Irrigation of

landscaped areas on or adjacent to the site can also cause a fluctuation of local groundwater levels. Evaluation of such factors is beyond the scope of our services. Based on the research and observed conditions, groundwater is not expected to impact the construction of the proposed development, although the historic high groundwater elevation needs to be considered in the geotechnical and structural design.

7. SEISMIC AND GEOLOGIC HAZARDS 7.1. General Seismic Setting The Southern California region is known to be seismically active. Earthquakes occurring within approximately 60 miles of the site are generally capable of generating ground shaking of engineering significance to the proposed construction. The project area is located in the general proximity of several active and potentially active faults, as shown on Figure 5 – Regional Faults and Seismicity Map. Active faults are defined as those that have experienced surface displacement within the Holocene period (approximately the last 11,000 years). Active faults within approximately 11 miles of the subject site include the Newport-Inglewood fault zone located 3.2 miles southeast of the site, the Whittier Fault located approximately 10.5 miles northeast of the site, and the Palos Verdes fault located approximately 11.4 miles south southwest of the site. The San Andreas Fault is located about 41 miles to the northeast of the site. An inferred trace of the potentially active Charnock fault, which trends sub-parallel to the northwest-trending Newport-Inglewood fault zone, is mapped approximately 9.1 miles to the west of the subject site. The Charnock fault has no record of historic earthquakes but shows evidence of displacement during late Quaternary time (Jennings, 2010). Table 3 lists selected principal known active faults that may affect the subject site and the maximum moment magnitude (Mmax) as published by Cao et al. (2003) for the California Geological Survey (CGS). The approximate distance to the site were calculated from Jennings (2010). Superimposed on the area map in Figure 5 are earthquake epicenters recorded by the USGS between 1900 to present day. A large amount of seismic activity and associated events with their epicenters have been recorded surrounding the project site. However, only relatively few earthquake epicenters have been recorded in the immediate area of the subject site. Notable historic earthquakes in Southern California of significance to the project include: • 1994 magnitude M6.7 Northridge earthquake on a blind thrust fault (low angle fault that is
not expressed at the ground surface) [Epicenter location: 34.21°N, 118.54°W]; • 1987 magnitude M5.9 Whittier Narrows earthquake on Puente Hills Blind Thrust Fault
[Epicenter location: 34.06°N, 118.08°W]; • 1971 magnitude M6.4 San Fernando earthquake which occurred on the San Fernando Fault
(of the Sierra Madre system) [Epicenter location: 34.42°N, 118.37°W]; • Two 1941 magnitude M4.8 Torrance-Gardena earthquakes which occurred on the Palos
Verdes Fault [Epicenter locations: 33.82°N, 118.22°W and 33.78°N, 118.25°W]; • 1933 magnitude M6.4 Long Beach earthquake on the Newport-Inglewood Fault [Epicenter
location: 33.63°N, 118.00°W]; • 1857 magnitude M7.9 Fort Tejon earthquake on the south central segment of the San Andreas
Fault [Epicenter location: 35.43°N, 120.19°W]. The most significant historic earthquakes near the project site were the 1933 Long Beach and 1994 Northridge earthquakes.

Potential seismic sources of significance to the project include active faults previously described and faults that are not known to break the ground surface but are considered active. This latter group of faults includes buried or “blind” thrust faults. Current tectonic models for the Los Angeles basin include the presence of buried thrust faults, several of which are considered partly responsible for the north-to-south compression of the basin. Although these faults are not currently zoned by the State of California for surface rupture hazards (Earthquake Fault Zones), many are considered capable of generating seismic shaking of significance to structures. Of these buried active faults the closest to the site is the Puente Hills Trust Fault (PHTF). The PHTF is currently defined as 3 separate but juxtaposed, generally east-west trending and north-dipping, fault surfaces that combined extend from Downtown Los Angeles to Brea. From west to east these include the Los Angeles, Santa Fe Springs, and Coyote Hills segments. Based upon recent studies by several researchers, including: Shaw et al., (2002), Olsen and Cooke (2005), and Leon et al. (2007), the three fault surfaces are interpreted to extend from depths in excess of 9 miles on the north side of the Los Angeles basin to less than 1.2 miles at the southerly limits of the fault surfaces in the central portion of the basin. Fault surface geometries are interpreted from historical petroleum exploration data, limited geotechnical subsurface exploration data, and limited seismicity (i.e.; the 1987 magnitude 5.9 Whittier Narrows earthquake).
M&D Properties Project No. TET 16-93E Plaza Mexico Residences January 13, 2017
Page 12
Leon et al. (2007) estimates that upwards of 60 percent of the total Los Angeles basin compression may be attributed to strain along the PHTF. Although ground rupture has not been officially attributed to the fault, the presence of youthful hills (e.g., Coyote Hills) and shallow folding at depth in the upper portion of the interpreted thrust ramp suggests recent activity. The PHTF is considered capable of generating earthquake magnitudes up to about Mw 7.0. 7.2. Surface Fault Rupture Official Maps of Earthquake Fault Zones were reviewed to evaluate the location of the project site relative to active fault zones. Earthquake Fault Zones (known as Special Studies Zones prior to 1994) have been established in accordance with the Alquist-Priolo Special Studies Zones Act enacted in 1972. The Act directs the State Geologist to delineate the regulatory zones that encompass surface traces of active faults that have a potential for future surface fault rupture. The purpose of the Alquist-Priolo Act is to regulate development near active faults in order to mitigate the hazard of surface fault rupture. The site is not located within a designated Earthquake Fault Zone for fault surface rupture hazard. Based on a review of State of California Earthquake Fault Zone maps, the closest zoned faults for surface rupture are within the Newport-Inglewood Zone Fault located approximately 3.2 miles southwest of the site and are mapped within the Inglewood Quadrangle (CDMG, 1986). No surface traces of any active or potentially active faults are known to pass directly through or project towards the site. Neither our field exploration nor literature review disclosed an active fault trace projecting to the ground surface in the project area. Therefore, the potential for surface rupture due to faulting occurring beneath the site during the design life of the proposed development is considered low. 7.3. Seismic Hazard Zones Maps of seismic hazard zones are issued by the California Geological Survey (CGS, formerly California Department of Conservation, Division of Mines and Geology (CDMG)) in accordance with the Seismic Hazards Mapping Act enacted in April 1997. The intent of the Seismic Hazards Mapping Act is to provide for a statewide seismic hazard mapping and technical advisory program to assist cities and counties in developing compliance requirements to protect the public health and safety from the effects of strong ground shaking, liquefaction, landslides, or other ground failure and other seismic hazards caused by earthquakes. Based on the review of the South Gate Quadrangle Official Map of Seismic Hazard Zones issued March 25, 1999 (see Figure 6), the proposed development is located within an area identified by the State of California as subject to the hazard of liquefaction. Because the site is located in a mapped area where the potential for liquefaction exists and due to the increase in the code-prescribed seismic demand since the Seismic Hazard Map was generated, a field investigation and analyses were performed to evaluate the site liquefaction potential per the 2013 CBC.

7.4. Liquefaction Potential and Dynamic Settlement Liquefaction of soils can be caused by ground shaking during earthquakes. Research and historical data indicate that loose, relatively clean granular soils and low plasticity silts are susceptible to liquefaction and dynamic settlement, whereas the stability of the majority of clayey silts, silty clays and clays is not typically adversely affected by ground shaking. Liquefaction is generally known to occur in saturated or near-saturated cohesionless soils at depths shallower than about 50 feet. However, layers of loose to medium dense sands were encountered at a depth greater than 50 feet, and therefore the liquefaction evaluation was extended to include coarse-grained materials to a depth of 60 feet. 7.4.1. Groundwater Level for Liquefaction Analysis Groundwater was encountered during the field explorations at a depths ranging between 30 and 45 feet. The historic high groundwater at the site was mapped by CDMG (South Gate Quadrangle) at a depth of about 8 feet. Therefore, a groundwater depth of 8 feet was assumed for evaluation of liquefaction potential at the site. 7.4.2. Soil Description Evaluation of liquefaction potential for the on-site materials was performed based on soil stratigraphy encountered in the field explorations. The encountered soil materials generally consisted of alluvial deposits made up of layers of soft to hard silts, and firm to very stiff lean and fat clays interspersed with layers of loose to dense silty sand, and medium dense to very dense poorly and well graded sands. Materials that are above the groundwater table are not considered susceptible to liquefaction. Thus, the liquefaction potential was evaluated only for soils encountered below a depth of 8 feet. Fine-grained soils as described in the following sections can undergo severe strength loss during ground shaking, and thus an evaluation of their sensitivity was also performed. 7.4.3. Liquefaction Seismic Demand Based on the USGS U.S. Seismic Design Maps website application (http://earthquake.usgs.gov/designmaps/us/application.php), for a site with coordinates 33.93024oN, -118.21807oW, the mapped Geometric Mean Peak Ground Acceleration (PGAM) was estimated to be approximately 0.654g for a site class D (assumed vs = 300 m/s), for a ground motion corresponding to the Maximum Considered Earthquake (MCE). From the Seismic Hazard Interactive Deaggregation website (https://geohazards.usgs.gov/deaggint/2008/) this ground motion approximately corresponds to a predominant earthquake magnitude of Mw 6.6 located at a distance of approximately 5.9 km (3.7 miles). These ground motion parameters were used in the liquefaction analyses.

7.4.4. Evaluation of Liquefaction Potential and Sensitivity Analyses Liquefaction potential of on-site soils was evaluated from SPT blowcounts as well as from CPT probes. Pervasive liquefaction potential was identified in all borings and probes. Liquefiable intervals were identified in various thickness and elevations at depths between 8 and 60 feet and composed about 35 to 50 percent of the soil profile within this interval. The liquefaction potential of cohesionless (sandy) soils was evaluated based on the SPT blowcounts and laboratory test results utilizing procedure published in Idriss and Boulanger (2008) monography publication on liquefaction evaluation, and generally as recommended in the County of Los Angeles Administrative Manual, Liquefaction/Lateral Spreading/GS045.0 dated October 6, 2014. The analyses based on Standard Penetration Tests (SPTs) considered an energy ratio correction factor CE of 1.25. This ratio is based on Table 5.2 of the Recommended Procedures for Implementation of DMG Special Publication 117, Guidelines for Analyzing and Mitigating Liquefaction in California (SCEC, 1999). For an automatic trip hammer the table suggests the energy ratio correction factor range from 0.9 to 1.6 (modified from Youd and Idriss, 1997). Consequently, the selected design energy ratio correction factor of 1.25 is an average and reflects a hammer efficiency of approximately 75 percent, which is consistent with our experience with similar equipment. The blowcounts recorded for soils driven with the 3-inch O.D. California Sampler with brass rings were converted to an equivalent SPT blowcounts using a reduction factor of 0.67. Borehole diameter correction factor CB of 1 based on the internal diameter of the hollow stem auger system used for the drilling was utilized in our liquefaction evaluation. Results of SPT-based liquefaction analyses of granular soils are summarized in Table 4 in the next section of this report and individually presented in Appendix D. Seismic sensitivity of fine-grained soils (clays and silts) was further evaluated per County of Los Angeles Administrative Manual GS045.0 with modifications proposed by Idriss and Boulanger (2008) and the fine-grained soils were classified in the following 3 categories: 1. Soils with Plasticity Index < 7 and below groundwater are classified as fine-grained soils
susceptible to liquefaction (typically includes silts);
2. Soils with Plasticity Index > 18 and a degree of sensitivity St > 6 are classified as fine-grained soils potentially susceptible to significant loss of strength during seismic shaking and require additional evaluation. The sensitivity of the on-site fine-grained soils is evaluated based on the water content, Atterberg limits, and effective vertical stresses using the procedures suggested by Holtz and Kovacs (1981) and Terzaghi, Peck and Mesri (1996).
3. Fine-grained soils falling outside the two categories above are considered to behave like
clays and are not considered susceptible to liquefaction or seismic sensitivity. Analyses of the sensitivity of the saturated fine-grained soils indicated low sensitivity based on the estimated sensitivity ratios of 1.9 to 4.5 as evaluated from Terzagi, Peck and Mesri (1996). The
M&D Properties Project No. TET 16-93E Plaza Mexico Residences January 13, 2017
Page 15
sensitivity was also estimated from the CPT data which indicates that the fine-grained soils at the site ranged in sensitivity between 0.9 and 4 with most values in the order of 1.1 to 2, i.e., significantly less than the accepted sensitivity threshold value of 6. Therefore these soils are not considered to be susceptible to undergo seismically induced loss of strength. Consequently, the potential for significant loss of strength of fine-grained materials and ensuing bearing failure or significant deformations during seismic shaking is considered low. The results of the sensitivity analyses for the soil borings are included in Appendix D. The liquefaction potential of the subsurface materials was also evaluated from the CPT data using the computer software CLiq v.2.0.6.97 by Geologismiki. The liquefaction susceptibility and the liquefaction induced settlements were evaluated using the Robertson (2009) method. Results of the liquefaction analysis using CPT data are summarized in Table 4 in the next section of this report and presented in Appendix D. 7.4.5. Dynamic Settlement Dynamic settlement can occur in both dry and saturated sands when loose to medium-dense granular soils undergo volumetric changes during ground shaking. Dynamic settlement can occur in saturated sands due to liquefaction or in dry sands due to densification of the soil matrix. The anticipated dynamic settlement of the saturated soils at the site was evaluated using SPT data from the current exploration using procedures outlined by Yoshimine et al (2006). The potential for dry dynamic settlement using SPT data was calculated according to the procedure outlined in Pradel (1998a and 1998b). The anticipated dynamic settlement of the saturated soils at the site was evaluated from the CPT data from the current exploration using the computer software CLiq v.2.0.6.9. The settlement of saturated soils was computed using the procedure outlined by Youd et al (2001). The potential for dry dynamic settlement was evaluated using the CPT data according to the procedure outlined in Robertson and Shao (2010). The details of dynamic settlement analyses are presented in Appendix F Table 4 presents the results of the liquefaction analyses and both the liquefaction-induced and the dry dynamic settlement.

As shown in Table 4, the combined dynamic settlement at the ground surface of the on-site soils for the southern parcel was estimated from the SPT data to range between 5 and 10 inches and from the CPT data to range between 7.8 and 10.8 inches. These results obtained by different methods match well and therefore increase confidence in their reliability. For total seismically induced settlements in excess of 4 inches application of ground modification methods and/or pile-supported foundations to mitigate the effects of settlement is necessary. Due to significant contributions to the total liquefaction induced settlement from liquefiable soil layers at depths greater than 35 feet (more than 4 inches of settlement), ground improvement is not considered to be an economical and feasible alternative at this site. Therefore, to mitigate the effects of liquefaction, pile-supported foundations are recommended.

7.5. Earthquake-Induced Landslides The site is not located in an Earthquake-induced Landslide Hazard Zone on the State of California Seismic Hazard Zones Map (see Figure 6). No evidence of landsliding was observed on or in the immediate vicinity of the site. Therefore the occurrence of an earthquake-induced landslide at the site is not considered to be a hazard to the site. 7.6. Subsidence Land subsidence is the lowering of the ground surface due to extraction or lowering of water levels or other stored fluids within the subsurface soil pores, or due to seismic activity which can the alluvial sediments to compact. Damage caused by subsidence can be visible cracks, fissures, or surface depression. There is no evidence that significant subsidence has occurred or may occur in the future at the site. Therefore, subsidence is not considered to be a hazard at this site. 7.7. Expansive / Collapsible Soils Action of soils exhibiting volumetric changes due to changes in moisture content affects the performance of the supported structures and improvements. Depending upon the supply of moisture in the ground, soils may experience changes in volume of up to thirty percent or more. Foundation soils which are expansive will “heave” and can cause lifting of a building or other structure during periods of high moisture. Conversely during periods of falling soil moisture, expansive soils will shrink which can result in structure settlement. Additionally, some unsaturated soils may be subject to collapse of the loose soil matrix due to dissolving of the cemented bonds within the matrix. The amount and rate of collapse is a function of mineralogy, percentage of clay, Atterberg limit values, cementing agents, etc. Observations and laboratory tests indicated that the on-site soils have a low expansion potential and therefore expansion of the near surface materials is not likely to be a problem at the site. Observations and laboratory tests indicated that the on-site soils have a degree of collapse slight to none.

8. DESIGN RECOMMENDATIONS 8.1. General Based on the results of the field exploration and engineering analyses, it is Tetra Tech’s opinion that the proposed construction is feasible from a geotechnical standpoint, provided that the recommendations contained in this report are incorporated into the design plans and implemented during construction. It is expected that a system of driven precast concrete piles connected by grade beams supporting a structural concrete slab can be efficiently used to support the proposed structures and mitigate the significant adverse effects of the design seismically-induced settlement. The recommended driven precast concrete pile foundation is expected to be installed relatively easily using conventional construction methods. An important benefit is that the installation does not generate any soil cuttings and thus minimizes the need to handle contaminated soil. Because of the large magnitude of the liquefaction induced settlement, a structurally supported slab spanning between pile caps and supporting the ground floor loads within the residential units is recommended. Within the parking structures an alternative of flor slab-on-grade could be considered since damage to the slab due to liquefaction-induced settlement following a design seismic event could be relatively readily repaired. Subgrade overexcavation and recompaction possibly in combination with geogrid reinforcement of the subgrade would still be required. This approach would result in need to potentially handle contaminated soil Cast-in-drilled-hole (CIDH) piers were also considered but because of the significant volume of excavated soil and the likely risk of handling contaminated material, this system is not expected to be cost effective. However, drilled displacement piles, also called auger pressure grouted displacement piles, although relatively costly, may be considered because they generate relatively minor drill cuttings volume but could provide higher load capacities, if needed, than the herein recommended driven precast concrete piles. A mat foundation system or perhaps a conventional shallow foundation pad and continuous footing system may be considered but it would require implementation of ground improvement to further reduce and control reduce the estimated seismically induced settlement to acceptable levels, i.e., less than about 4 inches of total settlement. Such ground improvement could include significant overexcavation and recompaction, use of intermediate foundation systems, e.g., rammed aggregate piers, use of geosynthetics, or combination of thereof. Given the need to mitigate a significant amount of settlement originating at relatively deep depths, these methods are likely to prove less effective. In addition, due to the likely need to handle and dispose contaminated on site soil, these ground improvement methods are not expected to be cost effective. Observations and laboratory tests indicate that the on-site soils have negligible levels of water-soluble sulfates, therefore, the soils are not expected to cause injurious sulfate attack on concrete with a minimum 28-day compressive strength of 2,500 psi. Observations and laboratory tests indicated that the on-site soils have a low expansion potential and therefore expansion of the near surface materials is not likely to be a problem at the site.

The design recommendations presented below reflect these considerations. The design recommendations presented below are based on Tetra Tech’s current understanding of the project. Once the project configuration is finalized and the design is complete, Tetra Tech should review the plans and specifications to evaluate if the geotechnical design recommendations have been incorporated as intended. 8.2. Clearing and Grubbing The construction area should be cleared of any pavement, structures, vegetation, trash and debris, prior to commencement of the site work. Any subterranean installations not to be preserved, such as pipes, utility collectors, tanks, older foundations, etc., should be abandoned and removed per Geotechnical Engineer’s recommendations and in accordance with applicable regulations. 8.3. Site Preparation No specific site preparation is required from the geotechnical perspective in the building areas where structures will be supported by the proposed pile and structural slab system. Some preparation may be, however, required to accommodate construction of the building protection system (BPS) under the buildings to control gas intrusion into the structures. It is expected that such subgrade preparation would require nominal scarification and recompaction to support BPS geomembrane. Specific recommendations may be provided once the BPS system is decided. In areas outside the building perimeter that will support various appurtenant structures and pavements the following recommendations for subgrade preparation are provided: Subgrade preparation for slabs and foundations for lightly loaded structures (e.g., trash
enclosures, landscape walls, or other appurtenant structures that are structurally separate from the main buildings) should consist of overexcavation and recompaction to a depth of at least 2 feet below the bottom of the foundation or floor slab, 2.5 feet below the existing grade, or to competent soils, whichever is deeper. To the extent practicable, the zone of overexcavation should extend outside the perimeter of the building area for a horizontal distance of at least 5 feet, but not less than a distance equivalent to the depth of overexcavation below the foundation bottom, except where existing adjacent foundations would be undermined.
Pavement areas and flatwork areas should be overexcavated and recompacted to a depth of at least 1.5 feet below the proposed subgrade elevation, or to uniform acceptable soils, whichever is deeper. To the extent practicable, the zone of overexcavation should extend a horizontal distance of at least 2 feet beyond the outside perimeter of the pavement.
In non-structural/landscaped areas, any existing soils may remain in place. However,
depending on the future use of the area, existing fill may be preferred to be excavated and replaced as engineered fill to accommodate future construction. This can be evaluated during grading.
M&D Properties Project No. TET 16-93E Plaza Mexico Residences January 13, 2017
Page 20
Disturbed soils at structural and non-structural areas will likely occur after demolition of existing site improvements. These soils should be overexcavated and recompacted to the total depth of the disturbed material.
The exposed overexcavation subgrade for all structures and slabs, should be probed and accepted by the Geotechnical Engineer. The soils should be scarified to a depth of 4 inches and compacted at a minimum of 110 percent of optimum moisture content to at least 90 percent of the maximum dry density, as evaluated by the latest version of ASTM D1557. Localized zones of loose and/or unstable soils may be encountered during the grading operations at the subgrade level and should be overexcavated and recompacted. If loose/soft/wet areas are encountered that are not practical to be excavated and processed, Table 5 below provides options for stabilizing the subgrade. The objective is to produce at least about 3 feet for foundations and 2 feet for pavements of competent fill to bridge over the impacted area. The specific type of remediation and associated area limits will need to be evaluated in the field by the Geotechnical Engineer.
Table 5 Conceptual Options for Handling Unstable Materials at the Excavated Subgrade
Areas where the soils are soft and/or unstable at the excavation subgrade
Overexcavate at least 3 feet for foundations, 2 feet for pavement areas Stabilize the soft subgrade by working open-graded aggregate material
(typically 3/4” or 1.5” crushed rock, coarser for softer subgrade) at least 4 to 6 inches into the soil.
Place non-woven geotextile, Mirafi 180N or approved equivalent, over the stabilized subgrade.
Place and compact well-graded fill (e.g., AB, CMB) or general approved backfill material to specified compaction over the geotextile.
Larger areas where the soils are excessively soft and/or unstable
Overexcavate at least 3 feet for foundations, 2 feet for pavement areas Improve the soft subgrade by working in open-graded aggregate
material as much as possible/practical into the subgrade. Place non-woven geotextile, Mirafi 180N or approved equivalent, over
the exposed soil. Place at least 8 inches (12-18 inches preferred) of well graded
aggregate material (e.g., AB, CMB); only reasonably achievable compaction is required.
Place non-woven geotextile, Mirafi 180N or approved equivalent, over the aggregate layer.
Place and compact fill to specified compaction over the geotextile. All fill placement associated with the replacement of the overexcavated soils, fill placed to achieve finish grade or subgrade, or utility trench backfill should be moisture-conditioned to at least 110 percent of the optimum moisture content and compacted to at least 90 percent of the maximum dry density, as evaluated by the latest version of ASTM D1557. The upper 1 foot of soils below pavements and any flatwork should be processed and compacted to at least 95 percent of the maximum dry density (ASTM D1557).

Excavated on-site soils may be re-used as compacted fill provided they are acceptable from the environmental contamination perspective, free of organics, deleterious materials, debris and particles over 3 inches in largest dimension. Locally, particles up to 6 inches in largest dimension may be incorporated in the fill soils based on specific approval and placement recommendations provided by the Geotechnical Engineer of Record during grading. In the event that any soil materials (including backfill or base course materials) are imported to the site, such soils should be sampled, tested, and approved by Tetra Tech prior to arrival on-site. In general, any soils imported to the site for use as fill should be predominantly granular and have an Expansion Index less than 30. Additional recommendations for site grading are provided in the “General Site Grading Recommendations” section of this report. 8.4. Temporary Slopes and Trench Excavations The on-site soils are not expected to pose unusual excavation difficulties, and therefore, conventional earth-moving equipment may be used. Localized sloughing/raveling of exposed soil intervals should be anticipated. All trench excavations should be performed in accordance with Cal-OSHA regulations. The on-site soils may be considered Type C soils to a depth of 20 feet as defined by the current Cal-OSHA soil classification. Unsurcharged excavations: Sides of temporary, unsurcharged excavations less than 20 feet deep should be sloped back at an inclination of 1.5(H):1(V) or flatter according to Cal-OSHA. Where space for sloped sides is not available, shoring will be necessary. All excavations where the bottom vertical height of the trench exceeds 4 feet must be shielded to a height of at least 18 inches above the top of the vertical side. Surcharge setback recommendations: Stockpiled (excavated) materials should be placed no closer than 4 feet from the top of the trench. A greater setback may be necessary when considering surcharge loads such as heavy vehicles, concrete trucks and cranes. This office should be advised of such heavy vehicle loadings so that specific setback requirements can be established for the used equipment. Alternatively, a shoring system may be designed to allow reduction in the setback distance. Personnel from Tetra Tech should observe the excavation progress so that appropriate modifications to the excavation design may be recommended, if necessary, due to encountered conditions differing from the design assumptions. 8.5. Temporary Shored Excavations Significant excavation is required for the construction for the proposed below grade parking structure. It is anticipated that the bottom of the pile caps will be at a depth of about 15 feet below existing grade level. If not enough space is available for sloped excavations, then shoring will be required. At these depths a cantilever soldier pile wall shoring will likely be adequate. Although a soldier pile wall with 1 row of tieback anchors or a soil nail wall shoring system may be required if lateral loads cannot be handled by soldier pile wall system alone.

Presented herein are preliminary design recommendations for a cantilevered and tieback and soil nail shoring systems based on the information available at this time. All components of the shoring system, including the penetration depth, should be designed by a specialist Registered Civil Engineer in the State of California and should further satisfy requirements of Cal-OSHA. It is recommended that all shoring designs be reviewed by the Geotechnical Engineer. Based on the encountered groundwater conditions, which are well below the historic high groundwater, groundwater is not expected to be an issue during construction. Therefore, the following recommendations are based on the assumption that the groundwater during construction is below the tips of soldier piles and no hydrostatic pressure can build up behind the shoring lagging. 8.5.1. Soldier Pile and Lagging Wall System Temporary soldier pile and lagging shoring system may be used to facilitate the proposed excavation. The soldier pile and lagging system would consist of steel soldier piles placed in drilled holes, backfilled with concrete. Tiebacks are usually required for excavation depths greater than about 15 feet. Alternate measures may be considered that would allow for elimination of the tiebacks such as installation of internal bracing, i.e., rakers, partial lowering of the grade just outside the excavation, or use of oversized soldier pile beams. 8.5.1.1. Soldier Pile Wall Design Table 6 below summarizes the governing geotechnical design parameters and loading diagrams for a cantilevered and tieback-supported soldier pile wall shoring system. These values are based on the following assumptions: 1. The shored soil grade is level at the ground surface; 2. There are no hydrostatic pressures behind the wall lagging; 3. There is no groundwater within the embedment depth of the soldier piles; and 4. The shoring is temporary.
Any surcharge (live or dead load) located within a 1(H):1(V) plane drawn up from the bottom of the excavation should be added to the lateral earth pressures. As a minimum, a 2 feet of uniform soil surcharge, i.e., 240 psf, is recommended to be included to account for nominal construction surcharge. The contribution of this vertical uniform surcharge to lateral loading on the shoring may be calculated by multiplying the surcharge by the coefficient of active lateral pressure. This office can provide recommendations for other surcharge configurations, if requested. To resist the lateral loading on shoring, the necessary depth of penetration of isolated soldier piles below the excavation bottom can be calculated based on the passive soil resistance provided in Table 6. Passive resistance should be ignored for the upper 12 inches below excavation bottom to account for potential near-surface soil disturbance. The passive resistance of individual soldier piles in Table 6 was increased to account for soil arching and factored by a Factor of Safety of 1.5. The provided value is applicable for soldier piles that are spaced no closer than 2 pile widths/diameters. For closer spacing the passive resistance would need to be reduced.

8.5.1.2. Tieback Design Friction tieback anchors may be used to resist lateral loads. For design purposes, it may be assumed that the active wedge adjacent to the shoring is defined by a plane drawn at 33 degrees with the vertical through the bottom of the excavation. The tieback bonded zone must not encroach inside the active zone. The unbonded length of the anchor should extend either a minimum of distance of H/5, where H is the height of the wall, or 5 feet behind the surface defined by the active wedge. Only the frictional resistance developed beyond the active wedge would be effective in resisting lateral loads. If the anchors are spaced at least 6 feet on centers, no reduction due to group action in the capacity of the anchors needs to be considered. The tieback anchors be detensioned after completion of the basement walls. Tiebacks are considered to assist with the lateral restraint of the shoring and to reduce soil movement behind the shoring wall. Straight shaft, pressure-grouted tiebacks may be initially designed for an allowable bond stress of 1,550 psf. The allowable bond stress includes a Factor of Safety of 2. The allowable bond stress should be verified at the beginning of the construction. The center of the anchor bond zone should be a minimum of 15 feet below the ground surface. The tieback bond stress may need to be adjusted for shallower tieback depths and/or depending on the grouting method. 8.5.1.3. Tieback Testing The bond stress and capacities of anchors should be verified by testing during construction. The tieback proof and performance testing program should be in compliance with the latest (4th edition) Post-Tensioning Institute (PTI) guidelines “Recommendations For Prestressed Rock And Soil Anchors”. This office should review and approve the actual testing program and observe and interpret the execution of the testing program.

8.5.1.4. Tieback Installation The anchors should be installed at angles between 15 and 30 degrees below the horizontal. Caving of anchor holes at certain locations should be anticipated and provisions should be made available to minimize such caving. The anchors should be filled with grout placed by pumping from the tip out, and the grout should extend from the tip of the anchor to the active wedge. To minimize the potential for caving, we suggest that the portion of the anchor shaft within the active wedge be backfilled with sand before testing the anchor. This portion of the shaft should be filled tightly and flush with the face of the excavation. The sand backfill may contain a small amount of cement to allow the sand to be placed by pumping. For post-grouted anchors the anchor may be filled with grout to the face of the shoring provided the tieback strands are enclosed in plastic sheathing. 8.5.1.5. Internal Bracing Locally, where tiebacks cannot be used, raker bracing may be used to internally brace the soldier pile wall. If used, raker bracing could be supported by temporary concrete footings (deadmen). For design of such temporary footings, poured with the bearing surface normal to the rakers inclined at 45 to 60 degrees from the vertical, a bearing value of 2,000 psf may be used, provided the shallowest point of the footing is at least 1 foot below the lowest adjacent grade. To reduce the movement of the shoring, the rakers should be tightly wedged against the footings and/or shoring system. 8.5.2. Soil Nail Wall A soil nail wall may be considered an option for the support of the temporary excavation. The soil nail wall alternative may be more economical than a soldier pile wall shoring system with tiebacks depending on the actual shoring configuration. 8.5.2.1. Soil Nail Wall Design Parameters to be used for the initial soil nail wall design are summarized in Table 7 below for the prevailing on-site silty soils for solid bar nails.

8.5.2.2. Soil Nail Testing Soil nail testing should be performed in accordance with the testing guidelines described in Chapter 9 of the FHWA Geotechnical Engineering Circular No.7 – Soil Nail Walls (FHWA-NHI-14-007) under the oversight of the Geotechnical Engineer. 8.5.3. Shoring System Deflection It is difficult to accurately predict the amount of deflection of a shored excavation as it largely depends on the quality of construction. It should be realized, however, that some deflection will likely occur. We estimate that for shoring systems designed consistent with the herein provided recommendation this deflection deflection could be on the order of 1 inch at the top of the shored excavation. If greater deflection occurs during construction, additional bracing or restraint may be necessary to minimize settlement of the nearby improvements. If it is desired to reduce the deflection of the shoring, a greater lateral earth pressure or a higher static Factor of Safety (e.g., greater than 1.5) could be used for the soldier pile or soil nail shoring system design, respectively. 8.5.3.1. Shoring System Construction Staging The shoring should be constructed utilizing a top-down method of construction whereas the soil is first partially excavated to produce a bench for installation of the topmost row of tiebacks or soil nails. The bench should not be excavated more than 5 feet below the elevation of the centerline of the tieback or soil nail row. If applicable, the shoring designer should analyze each stage of tieback or soil nail wall installation to ensure that the excavated bench level has an adequate Factor of Safety. 8.6. Deep Foundations The proposed buildings may be supported on a system of driven precast concrete piles connected by grade beams supporting a structural concrete slab. The driven precast concrete piles have the advantage of relative ease of installation, high production rate, and relatively high compressive axial capacity. Possible issues with driven piles may include noise and vibrations during installation and comparatively relatively smaller capacity than capacity of cast-in-drilled-hole piles. Because of the presence of deep liquefiable deposits up to a depth of about 60 feet, the piles need to extend sufficiently deep into the underlying competent soils in order to derive enough resistance to withstand downdrag forces due to seismically induced settlement. 8.6.1. Axial Loading Capacity Recommendations are provided herein for concrete 14-, 16-, and 20- inch square piles. Table 8 provides the recommended length and the estimated allowable axial downward and uplift capacities. The pile cap bottom has been assumed to be 5 feet below the adjacent finished grade / floor slab elevation. The allowable axial downward capacity was estimated using a Factor of Safety of 3 for the side and the end bearing resistances and for the uplift capacity. A one-third
M&D Properties Project No. TET 16-93E Plaza Mexico Residences January 13, 2017

increase may be used when considering wind or seismic loads. If driven piles with different capacities or cross-sections are desired, Tetra Tech should be contacted Tetra Tech should be contacted to provide appropriate recommendations. The tops of piles installed within the footprint of the parking structure basement will be located at a depth of about 11 feet below the tops of piles installed below the adjacent buildings. Since most of the pile capacity is derived from the end bearing in the dense zone below a depth of about 60 feet, the piles within the basement of the parking structure may be driven to the same tip elevation as the piles for the rest of the site i.e., the piles within the footprint of the parking structure basement would be about 54 feet long instead of 65 feet long, and the recommendations included in Table 8 remain applicable. Difficult driving conditions are not generally anticipated within the upper 60 feet. However, depending on the selected pile size, structural capacity, and driving equipment, some measures may need taken in order to drive the piles typically about 10 feet into the dense to very dense sand below a depth of about 60 feet. These measures may include a use of a driving shoe, drilling to assist driving (pre-drilling), or jetting. Initial considerations techniques to achieve the needed embedment depth include a requirement that the pre-drilled hole diameter be smaller than 80 percent of the pile cross-section diagonal. Neither pre-drilling nor jetting should be performed within 1 foot above the pile tip depth. The allowable shaft resistance for both compressive and axial capacity presented in Table 8 was reduced by 50 percent to account for the effects of pre-drilling.

Table 9 is provided to assist the contractor with selection of appropriate pile driving method.

For this case, the groundwater is considered at the same depth at which it was encountered during the field investigation, which is the condition anticipated during construction.

Table 9 also presents the ultimate axial compressive resistance for the extreme design condition when liquefaction has taken place and the associated seismically-induced settlement has imposed downdrag on the pile. An average undrained residual strength of 750 psf was assumed in the liquefiable layers for downdrag computations. The designer should consider the most critical case for the design of the piles and verify the structural integrity of the piles. The ultimate capacities presented in Table 9 are applicable for piles installed both within the footprint of the parking structure and the adjacent buildings.

The axial capacities provided in Tables 8 and 9 are maximum loads based solely on the geotechnical capacity of the soils. The loads for each design condition should be assessed by the Structural Engineer with regard to structural capacity of the piles. Typically, piles in groups should be spaced at least 3 pile widths on centers. If the piles are so spaced, no reduction in the capacities of the piles need be considered due to group action, unless large pile groups are required. In such a case this office should be contacted to provide appropriate recommendations. 8.6.2. Settlement
The settlement of the proposed structures due to dead and live loads, supported on driven piles in the manner recommended, is estimated to be less than 0.5 inch, excluding elastic compression of the piles. Differential settlement between adjacent columns is estimated to be less than 0.25 inch. 8.6.3. Lateral Loading Capacity
Table 10 presents the generalized soil parameters to be used with LPILE software (ENSOFT) for the analysis of laterally loaded piles. Note that the soil profile is provided in terms of depths below the existing prevailing grade. Therefore, the lateral analysis configuration needs to be set up with considerations for pile cap thickness and basement grade, as appropriate.

Lateral loads may be resisted by the piles and the passive resistance of the soils. The lateral capacity of the piles will depend on the permissible deflection and the degree of fixity at the top of the pile. This office can perform the analyses of the laterally loaded piles, if requested, when the pile selection is determined. Piles in groups may be considered to act individually when the center-to-center spacing is greater than 4 pile widths in the direction normal to loading and about 8 piles widths in the direction parallel to loading. Discussion below provides more detailed guidance. If the lateral load is normal (perpendicular) to the pile row, there would be a reduction of the lateral load capacity if the center-to-center spacing between piles is less than 4 times the diameter of a single pile. The p-multipliers presented in Table 12 are recommended by Caltrans California Amendments to AASHTO LRFD Bridge Design Specifications (2014), Section 10.7.2.4.

This office can provide pile group reduction multipliers for any specific pile configuration upon request. The passive resistance of compacted fill against pile caps and grade beams may be computed using the parameters for shallow foundations provided in Table 14. A one-third increase in the passive value may be used for wind or seismic loads. The resistance of the piles and the passive resistance of the soils against pile caps and grade beams may be combined without reduction in determining the total lateral resistance.
M&D Properties Project No. TET 16-93E Plaza Mexico Residences January 13, 2017

8.6.4. Installation Considerations
Piles in groups should be driven from the interior of the group outward. Piles should be checked for alignment and plumbness.
If drilling to assist driving (pre-drilling) is implemented to aid the pile installation, the pre-drilling should not be extend within 1 foot above the specified tip elevation. Caving and raveling of the pre-drill excavations should be anticipated. The auger for pre-drilling should have a cross-sectional area no larger than 80 percent of the cross-sectional area of the pile.
The pile hammer should be an approved diesel, steam, or air hammer that develops sufficient energy to drive piles at a penetration rate of not less than 1/8-inch per blow at the design load. The pile hammer should have a rated energy of at least 150P (ft-lbs), where P is the allowable compressive capacity in kips.
8.6.5. Pilot Test
We recommend that a full-scale compression static pile load pilot testing program be considered in accordance with FHWA NHI-05-042, Chapter 18. The pilot pile load testing should be performed according by procedures specified by ASTM D1143 using the quick load method. A total minimum of 2 tests is considered appropriate based on the size of the site. If a full-scale static pile load pilot testing program is not implemented we recommend that dynamic pilot pile testing and analyses (PDA) be performed prior to commencement of production pile installation and periodically during the production pile driving to evaluate the performance of the pile driving system, pile installation stresses, pile integrity, and to confirm static pile capacity. Blowcount pile driving criteria should be developed based on the selected pile and pile driving method and equipment and in conjunction with the results of the pilot pile driving testing and analyses. 8.6.6. Observations during Pile Driving All equipment, pile driving method and schedule should be reviewed by a representative of Tetra Tech prior to commencement of the installation activities. The pile driving operations should be observed and recorded continuously by a representative of Tetra Tech. The representative should evaluate that the design pile-tip elevations and blowcount criteria are achieved for each pile before termination of pile driving and review the periodic PDA testing results. Shallow Foundations for Appurtenant Structures Conventional shallow foundations may be used for lightly loaded structures such as trash enclosures, planter walls, and other similar structures that are not attached to the building superstructure.
M&D Properties Project No. TET 16-93E Plaza Mexico Residences January 13, 2017
Page 33
8.6.7. Design Parameters Shallow foundations should be designed using the geotechnical design parameters presented in Table 14. Footings should be designed and reinforced in accordance with the recommendations of the Structural Engineer and should conform to the 2013 California Building Code. The total allowable lateral resistance can be calculated as the sum of the allowable friction resistance and the allowable passive resistance. The passive resistance values may be increased by one-third when considering transient wind or seismic loading. 8.6.8. Footings Adjacent to Trenches The bottom of any trenches that are required for any buried utilities and piping should be kept outside a zone defined by a 1(H):1(V) plane projected from the outside bottom edge of any existing or proposed footings. Backfill materials and procedures shall conform to the recommendations provided in the “Site Preparation” and “General Site Grading” sections of this report. If any piping needs to be placed within the zone of influence, the pipes should be designed to account for the increased surcharge from the applied footing pressures and to withstand potential differential settlement between the surcharged and unsurcharged segments of the pipe. Generally, the pipes within the impacted zone should be protected with concrete encasement, utilidors, or other suitable form of protection. This office should be contacted to review any specific utility interaction configurations and their proposed mitigation.

8.6.9. Foundation Construction Observations Foundation excavations should be observed by a representative of Tetra Tech, and be clean of loosened soil and debris before placing steel or concrete. If soft or loose soils or other unsatisfactory materials are encountered, such materials should be removed and replaced with compacted fill prior to pouring the footing.

8.6.10. Exterior Slabs
The recommendations provided in the “Site Preparation” section of this report and in this section
are intended to help reduce the occurrence of cracks in concrete and associated horizontal
separation and vertical offset. However, it should be understood that concrete slabs may still crack
due to structural design or detailing, curing, or construction execution even when these
recommendations are implemented. If cracking of the concrete is desired to be minimized, the
reinforcement, concrete mix, and curing specifications should be designed appropriately by the
Structural Engineer and Concrete Specialist.
For design of concrete slabs, a modulus of subgrade reaction 1k on a 1-foot by 1-foot square plate
of 115 pounds per cubic inch may be used. For the on-site silty soils, the design modulus of
subgrade reaction for a rectangular base concrete element can be calculated as:
B
L
B
kk*5.1
)*5.01(
1
Where B and L are the width and length of the element in feet, respectively, while B is no more
than 14 times the thickness of the element, i.e., floor slab, and k is the design modulus of subgrade
reaction in pci.
In order to assist with initiation of the slab design, the slab-on-ground should have a minimum
thickness of 5 inches. The minimum reinforcement to reduce separation and offset of potential
concrete cracks should consist of No. 4 reinforcing bars spaced at 18 inches on-center, each way,
placed in the middle one-third of the section. Reinforcement should be properly placed and
supported on blocks or “chairs.” Welded wire mesh reinforcement is not recommended.
Control joints should be constructed in accordance with recommendations from the Structural
Engineer and the Architect. For preliminary design considerations, control joints should be
provided in all concrete slabs-on-grade as recommended by American Concrete Institute (ACI)
guidelines and at a maximum spacing (in feet) of 2 to 3 times of the slab thickness (in inches), but
generally no more than 10 feet,. All joints should form approximately square patterns to reduce
potential for randomly oriented shrinkage cracks. The control joints should be tooled at the time
of the pour or sawcut to ¼ of slab depth within 6 to 8 hours of concrete placement. All joints in
flatwork should be sealed to prevent moisture, vermin, or foreign material intrusion. Precautions
8.7. Seismic Design Parameters
The seismic design coefficients provided below in Table 15 are based on Chapter 16 of the
2013 California Building Code. According to the 2013 CBC, sites subject to liquefaction should
be classified as Site Class F, which requires a site response analysis to determine the site
acceleration response spectrum. However, ASCE 7-10, Section 20.3.1, which is the basis for the
2013 CBC, states that for structures with fundamental period of vibration equal or less than 0.5s,
site response analysis is not required to determine the site acceleration response spectrum and the
M&D Properties Project No. TET 16-93E
Plaza Mexico Residences January 13, 2017
Page 36
Site Class may be determined in accordance with Section 20.3, in which case this site may be
classified as a Site Cass D. The structural engineer shall verify that the natural period of the
structure meets this condition. If a site specific response is required, Tetra Tech can provide
such an analysis.

8.8. Retaining Walls and Basement Walls
Foundations for retaining walls with a retained height of soil lower than 6 feet may be designed
with the recommendations provided in Table 16 without including any seismic pressure
increments. Walls retaining more than 6 feet require the inclusion of not only static lateral
pressures but also of additional seismically induced lateral earth pressures as stipulated in the 2014
County of Los Angeles Building Code, which is based on the 2013 California Building Code
(CBC).
According to the 2013 CBC the dynamic seismic lateral earth pressures on foundation walls and
retaining walls should be determined using the design earthquake ground motions. Based on the
USGS U.S. Seismic Design Maps website application
(http://earthquake.usgs.gov/designmaps/us/application.php), the PGA from the Design Response
Spectrum at the site is approximately 0.47g where the design PGA is calculated as 0.4*SDS, where
SDS is the risk-targeted, maximum rotated acceleration direction, design response spectrum
parameter for short periods. The seismic induced earth pressure increments were estimated using
the method recommended by Mikola and Sitar (2013). These recommendations are provided in
Table 16. Lateral earth pressures presented in this table are for a level backfill.
Determination of whether the active or at-rest condition is appropriate for design will depend on
the flexibility of the walls. In walls with silty sand backfill that are free to rotate at least
0.002 radians (deflection at the top of the wall of at least 0.002 x H) may be designed for the active
condition. Walls that are not capable of this movement should be assumed rigid and designed for
M&D Properties Project No. TET 16-93E
Plaza Mexico Residences January 13, 2017
Page 37
the at-rest condition. The effect of any surcharge (dead or live load) located within a 1(H):1(V)
plane drawn upward from the heel of the wall footing should be added to the lateral earth pressures.
The on-site soils may be used as backfill material behind the site retaining walls provided they are
not contaminated and are approved by the Geotechnical Engineer. Alternatively, an approved
import material should be used for the backfill behind the wall. Suitable backfill materials should
have a Sand Equivalent of about 30, an Expansion Index of less than 20, and fines content (passing
#200 sieve) of less than 15 percent. The materials that are approved as backfill materials should
be moisture-conditioned at or above optimum moisture content, and placed in horizontal lifts not
more than 8 inches in uncompacted thickness, and compacted to at least 90 percent of the
maximum dry density, as evaluated by the latest version of ASTM D1557.
Retaining and basement walls should be constructed to limit potential for hydrostatic pressure
built-up behind the wall or be designed to withstand hydrostatic forces. If irrigation or
precipitation infiltration is expected, adequate drainage is essential to provide a free-drained
backfill condition to limit the hydrostatic buildup behind the wall. If control of efflorescence on
the air side of the wall due to moisture transmission through the wall is desired, the wall should be
appropriately waterproofed. However, efflorescence can also develop from the air side due to
irrigation overspray. Adequate drainage and waterproofing behind the wall may be provided by a
backdrain consisting of a geosynthetic drainage composite such as TerraDrain, MiraDrain, or
approved equivalent, placed against the entire backside of the wall. The drainage composite should
be connected to a 4-inch-diameter perforated ABS or PVC Schedule 40 drain pipe, or an approved
equivalent, placed at the base of the wall. The drain pipe should be sloped at least 2 percent and
surrounded by 1 cubic foot per foot of the Class II Permeable Material (Caltrans Standard
Specifications - Section 68), or by ¾-inch crushed rock (Standard Specification for Public Works
Construction (“Greenbook”) - Section 200-1.2) wrapped in suitable non-woven filter fabric, e.g.,
Mirafi 140NL or approved equivalent. Perforations in the drain pipe should have a maximum
diameter of 0.25 inches or 3/8 inches for Class 2 Permeable or ¾-inch crushed rock drain material,
respectively, spaced 3 inches on center, and be arranged in 2 rows at a radial spacing of
approximately 120 degrees. The axis of the included angle between the perforation rows should
be positioned downward to form a flowline. The drain pipe should discharge through a solid pipe
to appropriate outlets, such as the storm drain system or through the wall. The maximum length
of the drain pipe between discharge outlets should not exceed 200 feet.

The appropriate total seismic force (active plus seismic increment for yielding walls and at rest plus seismic increment for non-yielding walls) should be calculated be assuming a downward increasing tringle equivalent fluid pressure distribution. The resulting force should be assumed to act at 1/3 of the height of the wall above the bottom of the wall.
Pressure based on soil with ϕ = 27o, c = 0 psf, γt = 120 pcf (above groundwater), γt = 125 pcf (below groundwater) The 2013 CBC requires that basement walls be designed for at rest earth pressures for static conditions.
Legend: z … Depth (ft) below the grade behind the wall –depth measured from the ground surface to the depth where
the soil lateral pressure is being evaluated; z1 … Depth (ft) below the grade where passive conditions apply, i.e., usually in front of the wall – depth
measured from the ground surface to the depth where the soil lateral pressure is being evaluated; zw … Depth to groundwater (ft) – depth measured from the ground surface to the groundwater; dw … Depth of water along the wall height (ft) – measured from the groundwater table to the bottom of the
structure; Q … Uniform surcharge (psf) within a 1(H):1(V) plane drawn upward from the heel of the wall footing.
Because the historical high groundwater depth is at 8 feet, the basement walls under the parking structure need to be waterproofed in accordance with 2013 CBC, Section 1805 unless permanent dewatering systems are installed that keep the water table at least 2 feet below the basement grade elevation in which case the walls should be damp proofed.

8.9. Embedded Posts and Poles at Grade 8.9.1. Non-Constrained Case For the non-constrained case where the pole is not restricted to move at the ground level, the minimum depth of embedment required to resist lateral loads should be determined in accordance with the 2013 CBC Section 1807.3.2.1. The allowable static lateral soil bearing pressure can be assumed to be equal to 160 pcf equivalent fluid density (pcf EFD). Where bare ground (without concrete or asphalt cover) is present adjacent to the foundation, the lateral resistance should be ignored for the upper 12 inches below grade. Therefore, a trapezoidal pressure distribution should be used starting at 12 inches below grade. The allowable passive earth pressure value incorporates a Factor of Safety of 2. Vertical compressive loading can be resisted utilizing an allowable end bearing pressure of 1,600 psf. 8.9.2. Constrained Case For the constrained case where the pole is restricted from movement at the ground level by encasement in surrounding concrete or similar, the minimum depth of embedment required to resist lateral loads should be determined in accordance with the 2013 CBC, Section 1807.3.2.2. The allowable static lateral soil bearing pressure can be assumed to be at least 160 pcf EFD. The constrained earth pressure value incorporates a Factor of Safety of 2. Vertical compressive loading can be resisted utilizing an allowable end bearing pressure of 1,600 psf. 8.10. Pavement Sections New pavements for driveways are anticipated to be constructed around and throughout the development. 8.10.1. Subgrade Preparation The subgrade preparation and fill placement in the areas to be paved should conform to the recommendations provided in the “Site Preparation” and “General Site Grading” sections of this report. 8.10.2. Asphalt Concrete Pavement Design Flexible pavement sections have been evaluated in general accordance with the Caltrans Highway Design Manual method for flexible pavement design using a 20-year design life period. It is estimated that the access roads may be designed for a Traffic Index of 5. If fire access is required, a Traffic Index of 5 or 6 is typically acceptable to regulatory agencies. Based on the prevailing on-site subgrade silty soils R-value of 15 was assumed. The resulting recommended pavement sections are presented in Table 17.

Asphalt concrete and aggregate base should conform to the Specifications for Public Works Construction (Green Book) Sections 203-6 and 200-2, respectively. The aggregate base course should be compacted to 95 percent or more of the maximum dry density, as evaluated by the latest version of ASTM D1557. 8.10.3. Portland Cement Concrete Pavement Design Portland cement concrete (PCC) pavement sections are presented in Table 18. The PCC pavement sections may be placed directly on uniformly compacted subgrade soils to reduce potential for moisture infiltration and degradation of the subgrade. Alternatively, the PCC pavement be placed on at least 4 inches of aggregate base compacted to 95 percent or more of the maximum dry density (ASTM D 1557). The 4-inch aggregate base is not required from the pavement structural design perspective but provides a desired separation from the underlying potentially corrosive soils, assists with curing, and for constructability reasons. Optionally, the pavement sections may be reinforced with No. 3 reinforcing bars spaced 18 inches on center, each way, to reduce the potential for shrinkage cracking. Reinforcement steel and tie bar requirements should meet ACI recommendations.
The average daily truck traffic (ADTT) has been assumed for this project. The PCC pavement sections were designed for a theoretical 20-year design life based on the procedures suggested by the American Concrete Institute (ACI) Committee 330 (ACI 330R-01, 2001). Contraction, construction and isolation joints should be placed per ACI recommendations.

Note: 1Average Daily Truck Traffic; 8.10.4. Pavement Construction Observations The preparation of the pavement subgrade and the placement of base course and pavement sections should be observed by Tetra Tech personnel. Careful observation is recommended to evaluate that the pavement subgrade is consistent with the design assumptions and that it is uniform and uniformly compacted and that the recommended pavement and base course thickness are achieved. Paved areas should be properly sloped, and surface drainage facilities should be established to reduce water infiltration into the pavement subgrade. Curbing located adjacent to paved areas should be founded in the soil subgrade in order to provide a cutoff to reduce water infiltration into the base course.

8.11. Soil Corrosion The corrosion potential of the on-site materials to buried steel and concrete was evaluated based on laboratory testing on 2 representative soil samples. Table 19 below presents the results of the corrosivity testing.

Category S0 per 2013 CBC
Per 2013 CBC/ 2012 IBC, Section 1904.1, concrete subject to exposure to sulfates shall comply with the requirements set forth in ACI 318, Section 4.3. Based on the measured water soluble sulfate results the exposure of buried concrete to sulfate attack should be considered “not applicable”, i.e., exposure class S0 per ACI 318, Table 4.2.1. Consequently, injurious sulfate attack is not anticipated for concrete with a minimum 28-day compressive strength of 2,500 psi. Per 2013 CBC, Section 1904.1, concrete reinforcement should be protected from corrosion and exposure to chlorides in accordance with ACI 318, Section 4.3. The potential for corrosion of buried metals was evaluated based on the minimum resistivity and our experience with similar soils. The on-site soils are anticipated to likely have a “severe” corrosion potential to buried ferrous metals. A corrosion specialist should be consulted regarding suitable types of piping and necessary protection for underground metal conduits. The corrosion potential of the on-site soils should be verified during construction for each encountered soil type. Imported fill materials should be tested prior to placement to confirm that their corrosion potential is not more severe than the one assumed for the project. 8.12. Drainage Control The intent of this section is to provide general information regarding the control of surface water. The control of surface water is essential to the satisfactory performance of the building construction and site improvements. Surface water should be controlled so that conditions of uniform moisture are maintained beneath and adjacent to the structure, even during periods of heavy rainfall. The following recommendations should be considered as minimal.
Ponding and areas of low flow gradients should be avoided. Paved surfaces within 10 feet from the building foundation should be provided with a
gradient of at least 2 percent sloping away from improvements. Bare soil, e.g., planters, within 10 feet of the structure should be sloped away from the
improvement at a gradient of 5 percent. Positive drainage devices, such as graded swales, paved ditches, and/or catch basins should
be employed to accumulate and convey water to appropriate discharge points. Concrete walks and flatwork should not obstruct the free flow of surface water.
M&D Properties Project No. TET 16-93E Plaza Mexico Residences January 13, 2017
Page 43
Area drains should be recessed below grade to allow free flow of water into the basin. Enclosed raised planters should be sealed at the bottom and provided with an ample flow
gradient to a drainage device. Recessed planters and landscaped areas should be provided with area inlet and subsurface drain pipes.
Planters should not be located immediately adjacent to structures. If planters are to be located adjacent to a structure, they should be positively sealed, should incorporate a subdrain, and should be provided with free discharge capacity to a drainage device.
Planting areas at grade should be provided with positive drainage. Wherever possible, the grade of exposed soil areas should be established above adjacent paved grades. Drainage devices and curbing should be provided to prevent runoff from adjacent pavement or walks into planted areas.
Gutter and downspout systems should be provided to capture discharge from roof areas. The accumulated roof water should be conveyed to an off-site disposal area by a pipe or concrete swale system.
Landscape watering should be performed judiciously to preclude either soaking or desiccation of soils. The watering should be such that it just sustains plant growth without excessive infiltration. Sprinkler systems should be checked periodically to detect leakage and irrigation efforts should be reduced or halted during the rainy season.

9. GENERAL SITE GRADING RECOMMENDATIONS The intent of this section is to provide general information regarding the site grading. Site grading operations should conform with applicable local building and safety codes and to the rules and regulations of those governmental agencies having jurisdiction over the subject construction. The grading contractor is responsible for notifying governmental agencies, as required, and a representative of Tetra Tech at the start of site cleanup, at the initiation of grading, and any time that grading operations are resumed after an interruption. Each step of the grading should be accepted in a specific area by a representative of Tetra Tech, and where required, should be approved by the applicable governmental agencies prior to proceeding with subsequent work. The following site grading recommendations should be regarded as minimal. The site grading recommendations should be incorporated into the project plans and specifications. 1. Prior to grading, existing vegetation, trash, surface structures and debris should be removed
and disposed off-site at a legal dumpsite. Any existing utility lines, or other subsurface structures which are not to be utilized, should be removed, destroyed, or abandoned in compliance with current governmental regulations.
2. Subsequent to cleanup operations, and prior to initial grading, a reasonable search should be
made for subsurface obstructions and/or possible loose fill or detrimental soil types. This search should be conducted by the contractor, with advice from and under the observation of a representative of Tetra Tech.
3. Prior to the placement of fill or foundations within the building area, the site should be prepared
in accordance with the recommendations presented in the section “Site Preparation” of this report. All undocumented fill or disturbed soils within the building areas should be removed and processed as recommended by the representative of Tetra Tech.
4. The exposed subgrade and/or excavation bottom should be observed and approved by a
representative of Tetra Tech for conformance with the intent of the recommendations presented in this report and prior to any further processing or fill placement. It should be understood that the actual encountered conditions may warrant excavation and/or subgrade preparation beyond the extent recommended and/or anticipated in this report.
5. On-site inorganic granular soils that are free of debris or contamination are considered suitable
for placement as compacted fill. Any rock or other soil fragments greater than 6 inches in size should not be placed within 5 feet of the foundation subgrade.
6. Any imported fill material required for backfill or grading should be tested and approved prior
to delivery to the site. 7. Visual observations and field tests should be performed during grading by a representative of
Tetra Tech. This is necessary to assist the contractor in obtaining the proper moisture content and required degree of compaction. Wherever, in the opinion of a representative of Tetra Tech,
M&D Properties Project No. TET 16-93E Plaza Mexico Residences January 13, 2017
Page 45
an unsatisfactory condition is being created in any area, whether by cutting or filling, the work should not proceed in that area until the condition has been corrected.

10. DESIGN REVIEW AND CONSTRUCTION MONITORING Geotechnical review of plans and specifications and participation during the construction are an integral part of the design practice. The following paragraphs present our recommendations relative to the review of construction documents and the monitoring of construction activities. 10.1. Plans and Specifications The design plans and specifications should be reviewed and approved by Tetra Tech prior to bidding and construction, as the geotechnical recommendations may need to be re-evaluated in the light of the actual design configuration and loads. This review is necessary to evaluate whether the recommendations contained in this report have been incorporated into the project plans and specifications as intended. 10.2. Construction Monitoring Site preparation, pile installation, assessment of imported fill materials, fill placement, and other site grading operations should be observed and tested. The subgrade soils exposed during the construction may differ from those anticipated in the preparation of this report. Continuous observation by a representative of Tetra Tech should be implemented during construction to allow for evaluation of the soil conditions as they are encountered, and to provide the opportunity to recommend appropriate revisions as needed.

11. LIMITATIONS The recommendations and opinions expressed in this report are based on Tetra Tech’s review of background documents and on information obtained from the current geotechnical investigation. It should be noted that the scope of this study did not include the evaluation of the presence and/or extent of hazardous materials on any portion of the site although Tetra Tech is cognizant of the presence of such materials in certain portions of the site. Due to the limited nature of the field explorations, conditions not observed and described in this report may be present on the site. Uncertainties relative to subsurface conditions can be reduced through additional subsurface exploration. Additional subsurface evaluation and laboratory testing can be performed upon request. It should be understood that conditions different from those anticipated in this report may be encountered during grading operations, for example, the extent of unsuitable soil and the associated additional effort required to mitigate them. Site conditions, including groundwater level, can change with time as a result of natural processes or the activities of man at the subject site or at nearby sites. Changes to the applicable laws, regulations, codes, and standards of practice may occur as a result of government action or the broadening of knowledge. The findings of this document may, therefore, be invalidated over time, in part or in whole, by changes over which Tetra Tech has no control. Therefore, this report should reviewed and recertified if it were to be used for a project design commencing more than 1 year after the date of issuance of this report. Tetra Tech’s recommendations for this site are dependent upon appropriate quality control of the excavation for the construction of the underground storage tank and related facilities. Accordingly, the recommendations are made contingent upon the opportunity for Tetra Tech to observe grading and foundation installation operations, including installation of the temporary shoring. If parties other than Tetra Tech are engaged to provide such services, such parties must be notified that they will be required to assume complete responsibility as the Geotechnical Engineer of Record for the geotechnical phase of the project by concurring with the recommendations in this report and/or by providing alternative recommendations. This document is intended to be used only in its entirety. No portion of the document, by itself, is designed to completely represent any aspect of the project described herein. Tetra Tech should be contacted if the reader requires additional information or has questions regarding the content, interpretations presented, or completeness of this document. Reliance by others on the data presented herein or for purposes other than those stated in the text is authorized only if so permitted in writing by Tetra Tech. It should be understood that such an authorization may incur additional expenses and charges. Tetra Tech has endeavored to perform its evaluation using the degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical professionals with experience in this area in similar soil conditions. No other warranty, either expressed or implied, is made as to the conclusions and recommendations contained in this report.

SUMMARY
OF
CONE PENETRATION TEST DATA
1. INTRODUCTION This report presents the results of a Cone Penetration Test (CPT) program carried out for the project located at Beechwood Avenue & State Street in Lynwood, California. The work was performed by Kehoe Testing & Engineering (KTE) on October 25, 2016. The scope of work was performed as directed by Tetra Tech BAS personnel.
2. SUMMARY OF FIELD WORK The fieldwork consisted of performing CPT soundings at seven locations to determine the soil
lithology. Groundwater measurements and hole collapse depths provided in TABLE 2.1 are for information only. The readings indicate the apparent depth to which the hole is open and the apparent water level (if encountered) in the CPT probe hole at the time of measurement upon completion of the CPT. KTE does not warranty the accuracy of the measurements and the reported water levels may not represent the true or stabilized groundwater levels.

TABLE 2.1 - Summary of CPT Soundings
3. FIELD EQUIPMENT & PROCEDURES
The CPT soundings were carried out by KTE using an integrated electronic cone system manufactured by Vertek. The CPT soundings were performed in accordance with ASTM standards (D5778). The cone penetrometers were pushed using a 30-ton CPT rig. The cone used during the program was a 15 cm^2 cone and recorded the following parameters at approximately 2.5 cm depth intervals:
Cone Resistance (qc) Inclination
Sleeve Friction (fs) Penetration Speed
Dynamic Pore Pressure (u)
The above parameters were recorded and viewed in real time using a laptop computer. Data is stored at the KTE office for future analysis and reference. A complete set of baseline readings was taken prior to each sounding to determine temperature shifts and any zero load offsets. Monitoring base line readings ensures that the cone electronics are operating properly.
4. CONE PENETRATION TEST DATA & INTERPRETATION The Cone Penetration Test data is presented in graphical form in the attached Appendix. These plots were generated using the CPeT-IT program. Penetration depths are referenced to ground surface. The soil classification on the CPT plots is derived from the attached CPT Classification Chart (Robertson) and presents major soil lithologic changes. The stratigraphic interpretation is based on relationships between cone resistance (qc), sleeve friction (fs), and penetration pore pressure (u). The friction ratio (Rf), which is sleeve friction divided by cone resistance, is a calculated parameter that is used along with cone resistance to infer soil behavior type. Generally, cohesive soils (clays) have high friction ratios, low cone resistance and generate excess pore water pressures. Cohesionless soils (sands) have lower friction ratios, high cone bearing and generate little (or negative) excess pore water pressures. Tables of basic CPT output from the interpretation program CPeT-IT are provided for CPT data averaged over one foot intervals in the Appendix. Spreadsheet files of the averaged basic CPT output and averaged estimated geotechnical parameters are also included for use in further geotechnical analysis. We recommend a geotechnical engineer review the assumed input parameters and the calculated output from the CPeT-IT program. A summary of the equations used for the tabulated parameters is provided in the Appendix. It should be noted that it is not always possible to clearly identify a soil type based on qc, fs and u. In these situations, experience, judgement and an assessment of the pore pressure data should be used to infer the soil behavior type. If you have any questions regarding this information, please do not hesitate to call our office at (714) 901-7270. Sincerely,
KEHOE TESTING & ENGINEERING Richard W. Koester, Jr. General Manager 10/26/16-kk-7666
