Each core will be opened and described using standard soils and geomorphological <br /> techniques. Natural and or cultural stratigraphy will be identified whenever possible by <br /> carefully examining each core. If any paleosols or artifact-bearing soil horizons are <br /> encountered, they will be screened through wire mesh to recover any potential cultural <br /> constituents. Stratigraphic units (strata) and soil horizons will be ident�ed based on <br /> physicai characteristics such as composition, color, superposition, textural transitions, <br /> and pedogenic properties (i.e., relative soil development). Master soil horizons will be <br /> defined using standard United States Department of Agriculture soil taxonomy (Soil <br /> Survey Staff 2006). The locations of each bore will be recorded using a GPS device and <br /> plotted on high-resolution aerial photographs. <br /> A maximum of two samples will be submitted to Beta Analytic, Inc. for radiocarbon <br /> dating. Samples will consist of either plant material or bulk sediment. The radiocarbon <br /> samples will be used to determine the timing and duration of deposition and landscape <br /> stability throughout the APE. Samples wiil be selected in order to provide information on <br /> the initiation and cessation of deposition as well as the absolute duration of landscape <br /> stability. Samples will be selected in order to date extensive buried surfaces, and verify <br /> correlations based on pedogenic indicators observed in the field. <br /> A buried cultural deposit, if found, will be considered intact if the surrounding soil matrix <br /> has not been disturbed and the deposit is situated within a natural stratigraphic context. <br /> Should intact deposits be identified, Phase II evaluation of the site may be necessary, <br /> and recommendations will be made. Such Phase II evaluations are not included in this <br /> Scope of Work. In the event that an intact cultural deposit is identified and cannot be <br /> avoided by project impacts, Consultant will consult with City about the need to conduct <br /> Phase II excavations to evaluate whether a site is eligible for inclusion in the National <br /> Register of Historic Places for Section 106 compliance on federal undertakings. <br /> Task 3: Technical Reqort - A brief draft technical report of findings will be produced and <br /> submitted to Caltrans and City for review. The report will summarize analysis of <br /> observed subsurface profiles, results of radiocarbon dating analysis, the potential for the <br /> proposed project to affect buried archaeological sites, and relevant recommendations <br /> for mitigation measures if necessary. <br /> Consultant will attend one focused meeting with Caltrans to discuss the draft technical <br /> report and receive comments. Meeting notes will document the discussion and <br /> comments, and they will be incorporated into a final technical report, which will be <br /> submitted to Caltrans and the City, and integrated into Consultant's respective existing <br /> cultural resources reports. <br /> REV:04-07-15 VR <br /> Page 5 of 7 <br /> A-5 <br /> ATTY/AGR.Amend No.2/URS <br />
