CITY OF SANTA ANA ENVIRONMENTAL CONSULTANTING SERVICES QUALIFICATIONS Archaeological Data Recovery Excavations - Zone 4 and Zone D Booster Pumping Stations Project Irvine Ranch Water District Archaeological data recovery excavations were conducted within the Bonita/Coyote Canyon drainage about 2.5 miles southeast of the Newport Back Bay in Orange County for the Irvine Water District's construction of booster pumping stations as part of compliance with Appendix K of CEQA and its implementing guidelines. Ten data recovery units were excavated midden between May 30 and June 10, 1991. The data were analyzed in the context of previous test excavations conducted at the same site for the San Joaquin Hills Transportation Corridor project. The purpose of the excavations was to obtain a representative scientific sample of cultural material from that part of the site to be directly impacted by the construction. A comprehensive report was prepared of the data analysis, including several detailed appendices. Biological Resource Analysis of Environmental Health and Safety Services Building Site University of California at Irvine University of California, Irvine (UCI) planned to build an Environmental Health and Safety Services facility on approximately 3 acres of undeveloped land in the west campus area. Chambers Group conducted a biological survey to characterize the general vegetation and wildlife resources at the site, evaluate the site's potential to support sensitive plant and animal species, assess potential impacts of development on these resources, and verify the applicability of the Long Range Development Plan EIR mitigation measures to reduce or eliminate significant impacts of the project. Ford Road Archaeological Test Program and Construction Monitoring Sverdrup Corporation An archaeological test program was conducted for five sites in the New Ford Road right-of-way in Irvine, Orange County, California. Shovel test probes were used to assess site boundaries and units were used to sample site contents and assess integrity. The five sites were evaluated for NRHP eligibility as part of the Section 106 process. The Corps of Engineers was the lead agency because a Section 404 permit was required for road construction. A data recovery plan for mitigation of the two eligible sites to be impacted by road construction was prepared and approved by the Corps, State Historic Preservation Officer, and the Advisory Council on Historic Preservation. Monitoring of construction was also performed under this contract. Data Recovery at CA -ORA -106 and CA -ORA -482, Ford Road Project Sverdrup Corporation Data recovery excavations were conducted at ORA -106 and ORA -482 on Bonita Mesa in Irvine. Work was limited to the portions of the sites being impacted by road construction. A magnetometer program was performed at ORA -106 to locate fire -affected rock features. Seven features were located and excavated. A total of 104 systematically and judgmentally placed 1m by 1m excavation units were completed at ORA -105, and 15 systematically placed units were excavated at ORA -482. Research goals included determination of functional site type, reconstruction of activities, and obtaining evidence for resource intensification, including fire management. In addition to lithic and faunal analyses, obsidian hydration and sourcing, macrobotanical analysis, and organic residue analysis were performed.
