Section 5 <br />Alternative 2: Proposed Project <br />Based on the geotechnical evaluation prepared for the project site the Proposed <br />Project would be feasible from a geotechnical standpoint. To ensure geotechnical <br />stability the geotechnical recommendations from the Leighton Consulting <br />Geotechnical Report would be incorporated into the design and construction of <br />the project. The design recommendations include, Site Grading, Foundation and <br />Design Parameters, Slab-On-Grade, Lateral Earth Pressures, Seismic Design <br />Parameters, Pipeline Trench Subgrade and Backfill, Open Trench Construction <br />and Dewatering. With the implementation of GEO-2 potential onsite soil <br />constraints would be reduced to a less than significant level. <br />Alternative 3: Reduced Intensity Alternative <br />Because of similar geotechnical characteristics at Centennial Park and the <br />Heritage Museum, the geotechnical recommendations from Leighton Consulting <br />Geotechnical Report would be applicable for Alternative 3. With the <br />implementation of GEO-2 potential onsite soil constraints would be reduced to a <br />less than significant level. <br />Alternative 4: Pipeline Design Alternative <br />The geotechnical recommendations from Leighton Consulting Geotechnical <br />Report Would be applicable for Alternative 4. With the implementation of GEO-2 <br />potential onsite soil constraints would be reduced to a less than significant level. <br />Mitigation Measures <br />GEO-2: The final design and construction of the project will iincorporate the <br />geotechnical recommendations provided in the Leighton Consulting Geotechnical <br />Report prepared for the Mid Basin Centennial Park Injection Well Project, <br />Level of Impact <br />Alternative 1: No adverse impact <br />Alternative 2: Less than significant impact with Mitigation Measures GEO-2, <br />Alternative: 3: Less than significant impact with Mitigation Measures GEO-2 <br />Alternative 4.
