Comparison Table- Page 22 (July 30, 1993) <br /> If Amended Mitigation Implemented <br /> Potentially Significant Impacts Final EIR Suggested Mitigation Measures Amended Mitigation Measures Will Impact Be Less Than Significant? <br /> Known sites must be tested to determine the <br /> extent and type of contents, plus depth, <br /> integrity, age, and intrasite patterning (e.d. in <br /> depth, horizontal extent and artifact density), <br /> as follows: <br /> For the two newly recorded habitation <br /> sites (CA-SJO-0237,-0238,-0240),at least <br /> eight on by two meter test units in each <br /> should be excavated to the sterile level <br /> (approximately two meters); at least 20 <br /> obsidian hydration samples and at least <br /> five carbon-14 samples should be dated <br /> for each test unit. <br /> - For the lake site (CA-SJO-0011), at least <br /> 20 one by two meter test units should be <br /> excavated until a sterile level is reached <br /> (approximately three meters); at least 30 <br /> obsidian samples and at least 10 carbon- <br /> 14 samples should be dated for each test <br /> unit. <br /> - For the river site (CA-SJO-0043), at least <br /> 10 one by two meter test units should be <br /> excavated to a level of sterility <br /> (approximately three meters); at least 25 <br /> obsidian samples and at least eight <br /> samples of carbon-14 should be dated for <br /> each test unit. <br /> - Recordation, including mapping and <br /> photography, should follow (at minimum) <br /> the standard procedures of the <br /> Department of Parks and Recreation. <br />
