analyses, and temporary slope stability. Site -specific response spectra will also be developed if the project is to be designed using the dynamic procedure. Kleinfelder will analyze the field and laboratory data obtained, perform engineering analyses, and provide recommended design parameters for alternative foundation systems, including earthwork/grading, shallow spread foundations, transition cut/fill systems and reinforced mat or pile/pier systems (if required). The results of our field exploration, laboratory tests, and engineering analysis will be summarized in a written report, prepared under the supervision of a State of California Registered Geotechnical Engineer and Certified Engineering Geologist where needed. The reports will be prepared in accordance with The City of Santa Ana Municipal Code and professional standards established by the City, and/or federal, state, and local guidelines. We understand we have responsibility for our deliverables and anticipate that our report will include, at least, the following items: • Vicinity map and site plan showing approximate field exploration locations • Logs of borings • Discussion of field exploration methods • Discussion of laboratory test procedures used • Results of laboratory tests • Discussion of general subsurface conditions, including fill/bedrock contacts, bedrock orientation, seepage and groundwater conditions, as encountered in our field exploration • Discussion and evaluation of historic and recorded seismicity of the region and development of geologic map and cross section, if necessary • Research and review of available geologic, geotechnical and seismologic publications and maps covering the site and vicinity including the California Alquist-Priolo Earthquake Fault Zones map of the area • A review of aerial photographs covering the site area • A geologic reconnaissance of the site by engineering geologist to observe and map pertinent surface features indicative of possible geologic hazards • Evaluation of the researched data and discussion with conclusions regarding possible geologic hazards affecting the site and the proposed project • Site -specific response spectrum (if required), including review available pertinent geological and soil information to develop representative soil profile for the site and to estimate the site classification in order to use appropriate attenuation relationship in our analyses (site classification will be based on 2022 CBC) • Estimating Site Class per Chapter 16A of 2022 CBC • Performing probabilistic and deterministic seismic hazard analyses in order to develop site -specific seismic design criteria in terms of peak and spectral ground accelerations (SMs, SM,, Sps, and Sol) for the Maximum Considered Earthquake (MCE) and the Design Earthquake (DE) per Section 11.4.8 of ASCE 7. The analyses use, and therefore include regional faulting and seismicity. • Analysis of liquefaction potential and discussion of mitigation measures, if needed • Determination of earthquake induced settlement and lateral spreading at the site, if needed • Recommendations for foundation design including parameters for various alternatives, including: - Shallow footings, slabs -on -grade, and subgrade preparation KLE/NFELOER Nrigh!
