ENVIRONMENTAL IMPACT REPORT ADDENDUM <br />Bristol Street Widening Phase 111A — Civic Center Drive to Washington Avenue <br />important fossils. No greater impacts to paleontological resources than previously analyzed in the 1990 <br />FEISIEIR would result from Project implementation. <br />Mitigation Measures <br />No new additional mitigation measures are required. <br />d.) Disturb any human remains, including those interred outside of formal cemeteries? <br />The Project site is located within a highly urbanized area within the City of Santa Ana. No formal <br />cemeteries are located within the Project area or vicinity. However, in the event that human remains are <br />uncovered during grading or excavation, contractors are required to comply with the procedures and <br />requirements set forth in the California Health and Safety Code Section 7050.5 and CPRC Section <br />2098.98. The County Coroner and, in the event that the remains are Native American, the Native <br />American Heritage Commission would be notified and, in turn, would notify those persons believed to be <br />most likely descended from the deceased for appropriate disposition of the remains. The proposed Project <br />would not result in an impact to human remains greater than previously analyzed in the 1990 FEISIEIR. <br />Mitigation Measures <br />No new additional mitigation measures are required. <br />3.6 Geology and Soils <br />This section corresponds with Section IV - Environmental Consequences and Mitigation Measures, <br />Subsections A - Landform Modification, B - Seismic Hazards, C - Erosion Impacts, and F - Water <br />Quality, of the previously approved 1990 FEISIEIR. <br />a.)i Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo <br />Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other <br />substantial evidence of a known fault? Refer to Division of Mines and Geology Special <br />Publication 42. <br />The City of Santa Ana is not included in the Alquist-Priolo Earthquake Fault Zoning Map. The Project <br />site is not underlain by an active fault and the closest fault, the Newport -Inglewood Fault, is <br />approximately eight miles to the west. The proposed widening would not result in greater impacts than <br />previously analyzed in the 1990 FEISIEIR. <br />Mitigation Measures <br />No new additional mitigation measures are required. <br />a.)ii Strong seismic ground shaking? <br />The Ncwport-Inglewood Fault is the closest fault to the Project site and is the most likely source of <br />ground shaking impacts. The proposed Project is an intersection widening project and would not expose <br />people or structures to adverse ground shaking impact. The proposed widening would not result in greater <br />impacts than previously analyzed in the 1990 FEISIEIR. <br />Mitigation Measures <br />No new additional mitigation measures are required. <br />ANA 305-011 (PER 02) CITY OF SANTA ANA (U19/2015) YU PAGE 38 <br />
