is contained in the Building Evaluatign Forms found in the Append L X . AREA HISTORY FALEONTOLOGYi The following section of thin report was prepared by Mr. Rodney E. Raschke, an 0rangs County Certified Paleontologist. A review of the latest published geological map of the area revealed that 8ristoE street between First Atr-eet and Memory Larne is underlain by Quaternary alluvium (Murton et al . 1973) . These deposits were laid damn by the Banta Ana diver. Typically. these deposits are less than 10,000 years old. which makes them geologically tea young tc contain fossils. There are DO confirmed records of fossils from these oeposiis in the Ganta Ana area. There are unconfirmed guestionaU1e reports of the remains of "Ice Age" animals from the alluvium, However- "0 fossils are available to support tnQ5e reports. Quaternary a11"Vium is conside -ed to have E ?ow paleontoWgiWal sensitiaity cpotential for the discovery of foasil5}. Fused on the low paleontological sensitivity of the rock unit exposed in the aristvl Street area and the shallcy "ature of the excauatiuns associated with the proposed projoQ t, it is unlikeLy there will be any adverse impact on the paleontological reaources of the Sancta Ana area. Therefore rro paleontological monitoring will be neeee5ary during the wideninq of Bristol Street between First Street and Memory Larne. The above evaluation is based an a revieo of the publisher and ix-published iocality records of the Natural History Nuspum of Los Angeles County and thQ Natural History FoyDdatioD o�r orange County. No pale5vtological field survey was conducted during this study. ARCHAEOLOGY ChronWog : The Native Amer;oan group which once lived in the Study area are known as Gabrirelinu .
