<br />Soil Investigations for Data Collection in the Delta <br />Initial Study/Proposed Mitigated Negative Declaration 140 <br />ensure awareness about cultural resources, including identification of and <br />proper protocol for handling any unexpected finds. <br />Most overwater boring locations have not been previously surveyed (only two of 57 <br />have been subject to underwater remote sensing survey; ICF 2012; Panamerican <br />Consultants 2010). As the boring locations are underwater, a pedestrian survey of the <br />Area of Potential Effect (APE) is unfeasible, but pre-activity site visits as discussed in <br />MM-CUL-1 will still be conducted near the water on land to evaluate possibilities based <br />on what is visible from the land. This, along with underwater hazard surveys planned <br />as part of the project description, will provide sufficient field coverage for cultural <br />resources avoidance for overwater areas that have not been previously examined. <br />This is because they will identify any signs of structures, shipwrecks, objects, or other <br />forms of obstructions underwater and allow the boring location to be adjusted within <br />the APE to avoid hitting the obstruction. <br />For previously undiscovered historical resources that may be located subsurface, <br />MM CUL-2 through MM CUL-4 will provide training to those that will be present <br />during the soil investigations activities at the locations that have been cleared by <br />MM-CUL-1 and will aid in identification and prevention of substantial impacts to any <br />sub-surface previously undiscovered resources that may appear during boring and <br />CPT activities. Geophysical studies that do not involve any soil penetration would <br />not be at risk of damaging any sub-surface deposits. <br />b) Would this project cause a substantial adverse change in the significance of <br />an archaeological resource pursuant to Section 15064.5? <br />Less than Significant with Mitigation Incorporated. The Proposed Project as <br />designed would not cause a substantial adverse change in the significance of an <br />archaeological resource pursuant to CEQA Guidelines section 15064.5. There are <br />no known previously recorded archaeological resources within the Study Area. <br />Incorporation of mitigation measure MM CUL-1 would further reduce potential <br />impacts to less than significant for any unique archeological resources not currently <br />recorded. MM CUL-2 through MM CUL-4 will provide training to those that will be <br />present during the soil investigations activities at the locations that have been <br />cleared by MM-CUL-1 and will aid in identification and prevention of substantial <br />impacts to any previously undiscovered unique archaeological resources that may <br />appear during boring and CPT activities. Geophysical studies that do not involve any <br />soil penetration will not be at risk of damaging any sub-surface deposits. <br />c) Would this project disturb any human remains, including those interred <br />outside of formal cemeteries? <br />Less than Significant with Mitigation Incorporated. No known locations of human <br />remains are located within the Study Area. The Proposed Project would not disturb <br />any human remains with known locations, including those interred outside of formal <br />cemeteries. Incorporation of MM CUL-1 through AMM CUL-4 would ensure that any
