Introduction City of Santa Ana -Park View at Town and Country Manor Draft EIR maps from 1896 to 1942 were reviewed for the presence of historic age structures and development at the project area, as well as within the general vicinity. The results of this review showed that no structures or roads were located in the project area until 1942. The property was likely agricultural until the 1960's when commercial and housing development took place in the northern part of the City of Santa Ana and the southern section of the City of Orange. Once the upstream portions of Santiago Creek were modified to provide flood protection, development began in earnest. It is believed that no structures were located onsite until the existing Town and Country Manor was built in 1973. The results of the records search indicate that there are no known cultural resources located within the project site, and that the closest known resource is situated approximately 0.25 miles from the project site boundaries. Based on the results of the records search, existing land use, development within and adjacent to the project area, and the parameters of the proposed project, the potential for impacts to buried and potentially significant cultural resources is considered low. Although the modern ground surface has been highly disturbed, it is possible that paleontological resources could he below the ground surface within the boundaries of the project site. Adherence to a mitigation measure identified in the IS/NOP addressing paleontological resources and imposing a requirement for a paleontological review of the project site would reduce impacts to paleontological resources to less than significant. The project is not expected to impact human remains, including those interred outside of formal cemetenes. • Geology and Soils. A geotechnical engineering investigation was conducted by Geotechnologies, Inc. in February 2006. No known active or potentially active faults are believed to underlie the project site. In addition, the project site is not located within an Alquist -Priolo Earthquake Fault Zone. Geotechnologies, Inc. identified the San Joaquin Fault, about 5.7 miles away, as the closest earthquake fault. The primary geologic hazard at the site is considered to be moderate to strong ground motion (acceleration) caused by an earthquake on any of the local regional faults. The potential for surface ground rupture at the project site is considered low. Liquefaction analysis of the soils underlying the site was performed. Due to the depth of the proposed foundations, with the corresponding confining stress, seismically- induced settlement of the proposed structures should not be expected as a result of strong ground - shaking. The probability of seismically- induced landslides occurring on the site is considered to be insignificant due to the general lack of elevation difference across or adjacent to the site. The onsite soils are in the low expansion range. Special reinforcement considerations are not required. The proposed structure will have three levels of subterranean parking that will extend to a depth of as much as 30 feet below the ground surface. As a result, all of the fill soils will be removed from the site, and alluvium will be exposed at the foundation level.
