Section 5 <br />Alternative 3: Reduced Intensity Alternative <br />Under Alternative 3, the project would be implemented within the same Area of <br />Potential Effect. Similar to the proposed project, no adverse impacts would occur <br />to lands that contain recorded paleontological resources. Under Alternative 3, <br />there would be a reduced' amount of earthwork activity. Therefore, there would <br />be less potential to encounter lands that contain unknown paleontological <br />resources. With the implementation of Mitigation Measure CR-3 potential <br />adverse impacts to unknown cultural resources would be reduced to a less than <br />significant level. <br />Alternative 4: Pipeline Design Alternative <br />Under Alternative 4, the project would be implemented within the same Area of <br />Potential Effect. Similar to the Proposed Project, no adverse impacts would <br />occur to lands that contain recorded paleontological resources. Under Alternative <br />4, the amount of earthwork activity and level of potential impacts to unknown <br />paleontological resources would be similar to the proposed project. With the <br />implementation of Mitigation Measure CR-3 potential adverse impacts to <br />unknown paleontological resources would be reduced to a less than significant <br />level. <br />Mitigation Measure <br />CR-3: A qualified Paleontologist be notified and retained when earth-moving <br />activities are anticipated to impact undisturbed deposits in the Older Quaternary <br />Alluvium on the project sites. The designated Paleontologist should be present <br />during the pre-grade meeting to discuss paleontological sensitivity and to assess <br />whether scientifically important fossils have the potential to be encountered. The <br />extent of monitoring activities will be determined at the meeting in consultation <br />with the OCWD, If any scientifically important large fossil remains are uncovered <br />during earth-moving activities, the Paleontological Monitor will divert heavy <br />equipment away from the fossil site until s/he has had an opportunity to examine <br />the remains. Samples of Older Quaternary Alluvium should be collected for <br />processing and examination for very small vertebrate fossils. <br />Level of Impact <br />Alternative 1: No adverse impact <br />Alternative 2: Less than significant adverse impact with Mitigation Measure CR-3. <br />Alternative 3: Less than significant adverse impact with Mitigation Measure CR-3. <br />Alternative 4: Less than significant adverse impact with Mitigation Measure CR-3. <br />Mid Basin Centennial Park �l . bcd, 111M Project Final EIR 5-77 <br />
