Our services have been performed in general accordance with our proposal dated June 20, 2018 (revised on July 10, 2018), which you authorized on July 10, 2018. Our professional services have been performed using that degree of care and skill ordinarily exercised, under similar circumstances, by reputable geotechnical consultants practicing in this or similar localities. No other warranty, express or implied, is made as to the professional advice included in this letter. This letter has been prepared for Caribou Industries and their design consultants to be used solely for the proposed alternative seismic improvements to the existing building located at 888 North Main Street in Santa Ana, California. This letter has not been prepared for use by other parties, and may not contain sufficient information for purposes of other parties or other uses. 1.0 Background The proposed project is to consist of alternative seismic improvements to the existing office building located at 888 North Main Street in Santa Ana, California. We understand that the project requires an evaluation of ground motions having a 50% probability of being exceeded in 50 years. Basic Safety Ear-thquake 1 (BSE-lE per ASCE/SEI 41-13) were also requested to study damper forces in extreme conditions. The original building was constructed in the 1960s and housed the Security First National Bank. The existing building is up to 10 stories tall with one full and one partial subterranean parking level that extends 10 to 20 feet below the surrounding grade and is supported on drilled cast-in-place concrete pile foundations. The location of the site is illustrated on Figure 1, Site Vicinity Map. 'Wood' is a trading name for John Wood Group PLC and its subsidiaries ... 1-81--1Â¥9,-6-10 '1 00017 5 DIL5 Fopolf - CITY <ST Caribou Industries Proposed Alternative Seismic Improvements - 888 North Main Street July 25, 2018 Page 2 We previously performed the original geotechnical investigation for the subject building and submitted the results in a report dated March 6, 1964 (our Job No. 64054, submitted under the name of LeRoy Crandall and Associates, a Wood Environment & Infrastructure Solutions, Inc. legacy company). We also provided geotechnical inspection and testing services during the construction of the existing building, the results of which were documented in a report dated February 4, 1966 (our Job No. 64605, also submitted under the name of LeRoy Crandall and Associates). In addition, we recently performed a geotechnical investigation for the NOVA Children's Academy in the vicinity of the subject project site; the results of this investigation, which included a ground motion study and the development of four sets of response spectrum-compatible acceleration-time histories each for both the BSE-lE and the Basic Safety Earthquake 2 (BSE-2E) in accordance with the requirements of ASCE/SEI 41-13, were submitted in a report dated January 28, 2016 (our Job No. 4953-15-1481, submitted under the name of Amec Foster Wheeler Environment & Infrastructure, Inc., a Wood Environment & Infrastructure Solutions, Inc. legacy company). We were also provided a copy of a geotechnical investigation report for the nearby One Broadway Plaza project performed by Leighton Consulting, Inc. (Leighton), dated February 28,2006. Based on our review of the available data, we were to perform the following tasks: â€¢ Provide the results of our limited geologic-seismic hazards evaluation for the site, including evaluation of the liquefaction potential. â€¢ Provide the site-specific response spectrum for ground motions corresponding to the BSE-lE. â€¢ Provide the site-specific response spectrum for ground motions corresponding to an event with a 50% probability of being exceeded in 50 years (average return period of approximately 72 years). â€¢ Provide four sets of response spectrum-compatible acceleration time histories each for both of the ground motion levels described above. 2.0 Limited Geologic-Seismic Hazards Evaluation 2.1 Geologic Setting The project area is located on the Coastal Plain of Orange County, approximately 2 miles east of the Santa Ana River. The Coastal Plain of Orange County is underlain by a deep, structural basin known as the Los Angeles Basin. The site is underlain by approximately 3,600 feet of Quaternary sediments that are underlain by a thick sequence of Tertiary sedimentary rocks (approximately 7,000 feet). Regionally, the site is in the Peninsular Ranges geomorphic province. The province is characterized by elongate northwest-trending mountain ridges separated by straight-sided sediment-filled valleys. The northwest trend is further reflected in the direction of the dominant geologic structural features of the province that are northwest to west-northwest trending folds and faults, such as the nearby Whittier and Newport-Inglewood fault zones. Locally, the site is situated on a Holocene-age alluvial fan attributed to the Santa Ana River floodplain (Morton and Miller, 2006; Sprotte et al., 1980). The elevation at the site is approximately 128 feet above mean sea level (AMSL) (NAVD 88). ... Caribou Industries Proposed Alternative Seismic Improvements - 888 North Main Street July 25, 2018 Page 3 2.2 Geologic Materials According to published geologic reports and maps, the site is underlain by Holocene- to late Pleistocene-age alluvial fan deposits consisting generally of unconsolidated clay, silt and sand (Morton and Miller, 2006; Sprotte et al., 1980). Furthermore, our 1964 report for the site indicates admixtures of silt, clayey silt, sand and gravelly sand extending to the maximum explored depth of 71 feet below ground surface (bgs) (LeRoy Crandall and Associates, 1964). Fill soils were not encountered. Fill soils may be present between boring locations or as a result of subsequent construction or grading. The Quaternary-age alluvial deposits underlying the site are estimated to be about 2,000 feet thick and overlie Tertiary-age sedimentary bedrock (Sprotte et al., 1980). 2.3 Groundwater The site is located in the Coastal Plain of Orange County groundwater basin according to the California Department of Water Resources (DWR, 2003). Water level measurements from the Orange County Water District (OCWD) indicate that the water level in the principal aquifer was at approximately Elevation -35 at the site for June 2015 (OCWD, 2018). This elevation corresponds to a depth of 163 feet at the site. In our 1964 report, groundwater was not encountered in any exploratory boring drilled to the maximum drilled depth of 71 feet bgs (below ground surface). According to the OCWD (2015) and the California Geological Survey [CGS, previously the Division of Mines and Geology (CDMG)] the historic-high groundwater level is 40 feet bgs or deeper (CDMG, 1997). 2.4 Geologic-Seismic Hazards Fault Rupture The site is not within a currently established AIquist-Priolo Earthquake Fault Zone (A-P Zone) for surface fault rupture hazard (CGS, 2018a; CGS, 2002). An A-P Zone is an area which requires investigation to evaluate whether the potential for surface fault rupture is present near an active fault (CGS, 2018b). An active fault is defined as a fault with surface displacement within the last 11,700 years (Holocene). The closest active fault, and established A-P Zone, with the potential for fault surface rupture is the Newport-Inglewood fault zone, located approximately 9 miles southwest of the site (Jennings and Bryant, 2010; USGS-CGS, 2006; CGS, 2002). Faults with the potential for surface rupture are not known to be located directly beneath or projecting toward the site. In our opinion, the potential for surface rupture at the site due to fault plane displacement propagating to the ground surface during the design life of the project is considered low. Although the site could be subjected to strong ground shaking in the event of an earthquake, this hazard is common in Southern California and the effects of ground shaking can be mitigated by proper engineering design and construction in conformance with current building codes and engineering practices. Liquefaction Liquefaction potential is greatest where the ground-water level is shallow, and submerged loose, fine sands occur within a depth of about 50 feet or less. Liquefaction potential decreases as grain size and clay and gravel content increase. As ground acceleration and shaking duration increase during an earthquake, liquefaction potential increases. According to the CGS, the site is not within an area with a potential for liquefaction (CDMG, 1998). Groundwater was not encountered in any our prior borings to a maximum depth of 71 feet. Additionally, the historic-high groundwater level is documented to be 40 feet bgs or deeper (OCWD, 2015; CDMG, 1997). Therefore, the potential for liquefaction adversely impacting the project site is considered to be low. ... Caribou Industries Proposed Alternative Seismic Improvements - 888 North Main Street July 25, 2018 Page 4 Slope Stability The relatively flat-lying topography at the site precludes both stability problems and the potential for lurching (earth movement at right angles to a cliff or steep slope during ground shaking). There are no known landslides near the site, nor is the site in the path of any known or potential landslides (CGS, 2018c). Additionally, the site is not within an area identified as having a potential for earthquake-induced landslides (CDMG, 1998). Tsunamis, Inundation, Seiches, Flooding and Subsidence The site is not in a coastal area and at an approximate mean elevation of 128 feet AMSL. Therefore, tsunamis (seismic sea waves) are not considered a hazard at the site. According to the County of Orange Safety Element (2012), the site is not located downslope of any other large bodies of water that could adversely affect the site in the event of earthquake-induced dam failures or seiches (wave oscillations in an enclosed or semi-enclosed body of water). Therefore, the potential for inundation at the site as a result of an earthquake-induced dam failure is considered low. The site is located outside the 0.2% annual chance floodplain, Zone X, as defined by the Federal Emergency Management Association (FEMA, 2009). Therefore, the potential for flooding to affect the site is considered low. The site is not within an area of known subsidence associated with fluid withdrawal (groundwater or petroleum), peat oxidation, or hydrocompaction (City of Santa Ana, 2010). Oil Wells and Methane Gas The site is not located within the limits of an oil field according to the California Division of Gas and Geothermal Resources' Well Finder System (DOGGR, 2018). The closest known oil exploration wells are over one mile to the northeast and southwest of the site. Per DOGGR, the wells are classified as a "plugged." Although considered a remote possibility, abandoned wells or other undocumented wells could be encountered if excavations are performed. Any wells encountered should be abandoned in accordance with current DOGGR standards and regulations. Geologic Conclusions Based on the available geologic data, active or potentially active faults with the potential for surface fault rupture are not known to be located directly beneath or projecting toward the site. Therefore, the potential for surface rupture due to fault plane displacement propagating to the surface at the site during the design life of the proposed building is considered low. The site could be subjected to strong ground shaking in the event of an earthquake due to the close proximity to active faults. This hazard is common in Southern California and the effects of ground shaking can be mitigated by proper engineering design and construction in conformance with current building codes and engineering practices. The relatively flat-lying topography at the site precludes both stability problems and the potential for lurching (earth movement at right angles to a cliff or steep slope during ground shaking). The potential for other geologic hazards such as liquefaction, tsunamis, inundation, seiches, flooding, and subsidence affecting the site is also considered low. 3.0 Development of Site-Specific Response Spectra We have performed a Probabilistic Seismic Hazard Analysis (PSHA) using the computer program OpenSHA (Field et al. 2003) and a Deterministic Seismic Hazard Analysis (DSHA) using the computer program EZ-FRISK (Risk Engineering, 2015) in order to develop site-specific response spectra (RS) in accordance with the 2016 California ... Caribou Industries Proposed Alternative Seismic Improvements - 888 North Main Street July 25, 2018 Page 5 Building Code and ASCE/SEI 41-13. For the DSHA, a composite deterministic RS was compiled from the maximum of the 84th percentile spectral ordinates computed for known nearby faults. In addition to known fault sources, background seismicity was also included in the PSHA. In accordance with Section 2.4.2.1 of ASCE/SEI 41- 13, for sites located within 3 miles [5 kilometers (km)] of an active fault that controls the hazard of the site- specific response spectra, the ground motion calculations shall consider the effect of fault-normal and fault- parallel motions. The site is not near fault by this definition; therefore, fault-normal and fault-parallel motions were not considered. To convert to maximum direction ground motions, the multiplication factors recommended in Shahi and Baker (2014) were used. The site-specific probabilistic and deterministic RS were developed using the average ground motions obtained from the Next Generation Attenuation (NGA) West 2 relationships of Abrahamson et al. (2014), Boore et al. (2014), Campbell and Bozorgnia (2014), and Chiou and Youngs (2014). For all four NGA relationships, we have used an average shear wave velocity in the upper 30 meters (Vs,30) equal to 250 meters per second (m/s) based on the results of our shear wave velocity measurements near the site at the NOVA Children's Academy (Amec Foster Wheeler, 2016) and correlations of shear wave velocity using the SPT blow counts adjacent to the site presented in the Leighton repor-t (Leighton Consulting, 2006). The SPT blow counts were correlated to shear wave velocity using the method presented in the PEER Report No. 2010/03 (Brandenberg et al., 2010). Three of the borings in the Leighton report extended below 30 meters (m) (100 feet) and were used to estimate the Vs,30; the three borings were designated 8-5, HS-1, and HS-2. The results of the correlation gave Vs,30 values of 211, 270, and 273 m/s, respectively. We took the average of those results - 251 m/s - and compared it with the Vs,30 used at the NOVA Children's Academy (Amec Foster Wheeler, 2016), which was 248 m/s. We decided that a rounded value of 250 m/s is representative of the Vs,30 at the site because it lies between the two values being compared. Therefore, we used an average Vs,30 equal to 250 m/s in the analyses. We have used a depth to a shear wave velocity of 1,000 m/s beneath the site (Zi.o) of 400 m. We have used a depth to a shear wave velocity of 2,500 m/S (45) of approximately 4.55 km. These values were obtained from Cybershake (Crouse et al., 2018) which uses the latest Southern California Earthquake Center (SCEC) Community Velocity Model. The site-specific response spectrum for the BSE-l E Seismic Hazard Level was taken as the smaller of the following: 1. The mean probabilistic site-specific spectrum with a 20% probability of being exceeded in 50 years adjusted for maximum direction; or 2. The site-specific spectrum for the BSE-lN Seismic Hazard Level adjusted for maximum direction. The BSE-lN ground motion is determined from the BSE-2N ground motion. In accordance with ASCE/SEI 41-13 Section 2.4.2.1.4, the site-specific response acceleration parameters for the BSE-2N Seismic Hazard Level shall be determined based on the provisions for a Maximum Considered Earthquake (MCER) provided in Chapter 21 of ASCE 7-10. The BSE-2N response spectrum is obtained by computing both a probabilistic and a deterministic response spectrum. The site-specific BSE-lN response spectrum was computed by multiplying the ordinates of the site-specific BSE-2N response spectrum by two-thirds in accordance with Section 2.4.2.1.4 of ASCE/SEI 41-13. Additionally, a mean probabilistic site-specific spectrum with a 50% probability of being exceeded in 50 years (50-in-50) was calculated and adjusted for maximum direction. ... Caribou Industries Proposed Alternative Seismic Improvements - 888 North Main Street July 25, 2018 Page 6 The site-specific BSE-2N and BSE-l N response spectra for 5% of critical structural damping are presented in Table 1 and Figures 2 and 3. The site-specific BSE-lE and probabilistic 50-in-50 geometric mean and maximum direction response spectra for 5% of critical structural damping are shown in Table 2 and Figures 4 and 5. 4.0 Period Range of Interest The fundamental building period of 1.4 seconds was provided by Mr. Leonard Martin Joseph of Thornton Tomasetti. The upper bound period of 2.1 seconds was selected equal to 1.5 times the largest fundamental period in accordance with Section 2.4.2.2 of ASCE/SEI 41-13. The lower bound period of 0.28 seconds was selected equal to 0.2 times the fundamental period. 5.0 Seed Time Histories We have used the four sets of acceleration-time histories previously selected and spectrally matched to the BSE- lE response spectrum for the NOVA Children's Academy (Amec Foster Wheeler, 2016). Each set of time histories consists of two orthogonal horizontal ground motion components. Each component of each set of time histories was scaled to the new BSE-lE and 50-in-50 response spectra such that the response spectrum closely matched the target spectrum. The scaling factor used for the BSE-l E target spectrum was 1.054 and the scaling factor used for the 50-in-50 target spectrum was 0.65. In Table 3, we present a total of four time history records that were scaled to the BSE-lE and 50-in-50 response spectra. Also presented in Table 3 are the earthquake magnitudes, fault mechanisms, source-to-site (Joyner- Boore - Rjb) distance, site Vs,30, lowest usable frequency, significant duration (Ds.95), and pulse period (Tp). The plots of acceleration, velocity and displacement time histories of the two components of the candidate time histories as well as the respective spectral acceleration and square root sum of the squares (SRSS) of the two orthogonal horizontal response spectra are shown on Figure 6.1.la through Figure 6.4.3 and Figure 8.1.la through Figure 8.4.3 for the BSE-lE hazard level and the 50-in-50 hazard level, respectively. The average of the 'Hl' and 'H2' horizontal components and average of the SRSS spectra are presented in Figures 7 and 9 for the BSE-lE hazard level and the 50-in-50 hazard level, respectively. The digital data for the time histories will be transmitted electronically. ...
