PICTURES MASTER PLAN 5555 MELROSE AVENUE LOS ANGELES, CALIFORNIA, 90038 INTRODUCTION This report presents the results of the geotechnical engineering evaluation performed for the proposed Paramount Pictures Master Plan (The “Project”) that consists of improvements to Paramount Studios (the “Project Site”) in the Hollywood community of The City of Los Angeles, California. The purpose of this evaluation was to research the nature of the earth materials and geologic conditions underlying the site and vicinity for master planning purposes. This evaluation included review of published geologic data, review of available geotechnical engineering information and the preparation of this report. Exploratory excavation locations encountered in the review of available documents are shown on the enclosed Boring Location Map included herein as Attachment 1. This report is intended to provide general geologic and geotechnical information on the site. It is recommended that a site-specific geotechnical report should be prepared for each unique building project in accordance with applicable City requirements and all applicable recommendations included in this master plan evaluation report as discussed further below. EXECUTIVE SUMMARY The largest portion of the Project Site is the Main Lot which is bounded to the south by Melrose Avenue, to the west by Gower Street, to the east by Van Ness Avenue and to the north by a cemetery. Several ancillary properties are also included in the Project Site. These properties are Geotechnologies, Inc. 439 Western Avenue, Glendale, California 91201-2837 Tel: 818.240.9600 Fax: 818.240.9675 www.geoteq.com July 1, 2013 Revised April 15, 2015 File No. 20099 Page 2 the South Bronson Lot at the southwest corner of Melrose Avenue and Bronson Avenue; the Windsor Lot at the southwest corner of Melrose Avenue and Windsor Avenue; the Camerford Lot at the southwest corner of Camerford Avenue and Gower Street; the Waring Lot at the northwest corner of Gower Street and Waring Avenue; the Gregory Lot at the northwest corner of Gower Street and Gregory Avenue; and the Lemon Grove Lot at the northeast corner of Lemon Grove Avenue, and Van Ness Avenue. The soils underlying the Project Site consist of clays, silts, silty sands and sands. Artificial fill depths vary generally from 0 to 5 feet with local deposits reported as deep as 9 feet. The site soils are reported to vary from the very low to the very high expansion range. Most of the testing indicates that the soils fall within the moderate expansion range. Groundwater levels below the Project Site are highly variable. Groundwater has been encountered as shallow as approximately 8 feet and as deep as approximately 25 feet. It is most likely that the shallower occurrences of groundwater are perched conditions due to differences in permeability within the underlying soils. Monitoring well readings in the vicinity of the site indicate that groundwater is on the order of approximately

    BEACH BOULEVARD SPECIFIC PLAN DRAFT EIR CITY OF ANAHEIM 5. Environmental Analysis 5.4 GEOLOGY AND SOILS This section of the Draft Environmental Impact Report (DEIR) evaluates the potential for implementation of the Beach Boulevard Specific Plan (Proposed Project) to impact geological and soil resources in the City of Anaheim. 5.4.1 Environmental Setting Regulatory Setting California Alquist-Priolo Earthquake Fault Zoning Act The Alquist-Priolo Earthquake Fault Zoning Act was signed into state law in 1972. Its primary purpose is to mitigate the hazard of fault rupture by prohibiting the location of structures for human occupancy across the trace of an active fault. The act delineates “Earthquake Fault Zones” along faults that are “sufficiently active” and “well defined.” The act also requires that cities and counties withhold development permits for sites within an earthquake fault zone until geologic investigations demonstrate that the sites are not threatened by surface displacement from future faulting. Pursuant to this act, structures for human occupancy are not allowed within 50 feet of the trace of an active fault. Seismic Hazard Mapping Act The Seismic Hazard Mapping Act (SHMA) was adopted by the state in 1990 to protect the public from the effects of nonsurface fault rupture earthquake hazards, including strong ground shaking, liquefaction, seismically induced landslides, or other ground failure caused by earthquakes. The goal of the act is to minimize loss of life and property by identifying and mitigating seismic hazards. The California Geological Survey (CGS) prepares and provides local governments with seismic hazard zone maps that identify areas susceptible to amplified shaking, liquefaction, earthquake-induced landslides, and other ground failures.

  • Long-Term Fault Slip Rates, Distributed Deformation Rates, and Forecast Of
    1 Long-term fault slip rates, distributed deformation rates, and forecast of seismicity 2 in the western United States from joint fitting of community geologic, geodetic, 3 and stress-direction datasets 4 Peter Bird 5 Department of Earth and Space Sciences 6 University of California 7 Los Angeles, CA 90095-1567 8 [email protected] 9 Second revision of 2009.07.08 for J. Geophys. Res. (Solid Earth) 10 ABSTRACT. The long-term-average velocity field of the western United States is computed 11 with a kinematic finite-element code. Community datasets include fault traces, geologic offset 12 rates, geodetic velocities, principal stress directions, and Euler poles. There is an irreducible 13 minimum amount of distributed permanent deformation, which accommodates 1/3 of Pacific- 14 North America relative motion in California. Much of this may be due to slip on faults not 15 included in the model. All datasets are fit at a common RMS level of 1.8 datum standard 16 deviations. Experiments with alternate weights, fault sets, and Euler poles define a suite of 17 acceptable community models. In pseudo-prospective tests, fault offset rates are compared to 18 126 additional published rates not used in the computation: 44% are consistent; another 48% 19 have discrepancies under 1 mm/a, and 8% have larger discrepancies. Updated models are then 20 computed. Novel predictions include: dextral slip at 2~3 mm/a in the Brothers fault zone, two 21 alternative solutions for the Mendocino triple junction, slower slip on some trains of the San 22 Andreas fault than in recent hazard models, and clockwise rotation of some domains in the 23 Eastern California shear zone.
