ARCHAEOLOGICAL SURVEY REPORT FAIRVIEW STREET IMPROVEMENTS FROM 9TH STREET TO 16TH STREET AND JUNE 2019 BRIDGE REPLACEMENT PROJECT SANTA ANA, CALIFORNIA STUDY FINDINGS AND CONCLUSIONS A single fragment of Chione californiensis was found in the APE in an undeveloped area on the west side of Fairview Street just south of the Santa Ana River. No other cultural resources were found in the vicinity, thus the resource is an isolated find. Isolated finds are not considered important/significant under Section 106 of the National Historic Preservation Act or under the California Environmental Quality Act. Furthermore, Attachment 4 of the Caltrans PA (2014), identifies isolated prehistoric finds consisting of fewer than three items per 100 square meters (1,076 square feet) as exempt from evaluation. As such, the isolated shell fragment found in the current APE is not an important resource and requires no further evaluation. No additional archaeological resources were identified within the APE through archival research, Native American consultation, or the field survey. The majority of the APE consists of paved asphalt and concrete sidewalk along Fairview Street from Westminster Avenue/17th Street south to Civic Center Drive. A small amount of acreage also includes areas outside of the sidewalk including adjacent streets, and the building, lawn, and parking lot at 1002 North Fairview Street. The survey showed that all surveyable areas in the APE exhibited high levels of disturbance from road and bridge construction and adjacent home construction. Buried utilities have also added to the disturbance of the APE. The entire APE has been substantially altered during previous construction activities. As such, the likelihood of encountering intact archaeological resources is very low. UNIDENTIFIED CULTURAL RESOURCES If previously unidentified cultural materials are unearthed during construction, it is Caltrans' policy that work be halted in that portion of the project area until a qualified archaeologist can assess the significance of the find. Additional archaeological surveys will be needed if the project limits are extended beyond the present survey limits. Q:\WKE1702\Cu1tural\ASR\ASR 2019 OS-21.docx (06/03/19) 22
