ENVIRONMENTAL IMPACT REPORT ADDENDUM Bristol Street Widening Phase IIIA— Civic Center Drive to Washington Avenue important fossils. No greater impacts to paleontological resources than previously analyzed in the 1990 FEIS /EIR would result from Project implementation. Mitigation Measures No new additional mitigation measures are required. tb) Disturb any human remains, including those interred outside offormal cemeteries? The Project site is located within a highly urbanized area within the City of Santa Ana. No formal cemeteries are located within the Project area or vicinity. However, in the event that human remains are uncovered during grading or excavation, contractors are required to comply with the procedures and requirements set forth in the California Health and Safety Code Section 7050.5 and CPRC Section 2098.98. The County Coroner and, in the event that the remains are Native American, the Native American Heritage Commission would be notified and, in turn, would notify those persons believed to be most likely descended from the deceased for appropriate disposition of the remains. The proposed Project would not result in an impact to human remains greater than previously analyzed in the 1990 FEIS /EIR. Mitigation Measures No new additional mitigation measures are required. 3.6 Geology and Soils This section corresponds with Section IV - Environmental Consequences and Mitigation Measures, Subsections A - Landform Modification, B - Seismic Hazards, C - Erosion Impacts, and F - Water Quality, of the previously approved 1990 FEIS/EIR. a.)i Rupture of a known earthquake fault, as delineated on the most recent Alquist- Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. The City of Santa Ana is not included in the Alquist - Priolo Earthquake Fault Zoning Map. The Project site is not underlain by an active fault and the closest fault, the Newport- Inglewood Fault, is approximately eight miles to the west. The proposed widening would not result in greater impacts than previously analyzed in the 1990 FEIS/FIR. Mitigation Measures No new additional mitigation measures are required. a.)ii Strong seismic ground shaking? The Newport- Inglewood Fault is the closest fault to the Project site and is the most likely source of ground shaking impacts. The proposed Project is an intersection widening project and would not expose people or structures to adverse ground shaking impact. The proposed widening would not result in greater impacts than previously analyzed in the 1990 FEIS/EIR. Mitigation Measures No new additional mitigation measures are required.
