This vibration level would be well <br />within Caltrans 0.250 inch per second PPV threshold of perception for transient <br />sources. Therefore, a less than significant vibration impact would occur from <br />construction and operation of the Proposed Project. <br />Alternative 3: Reduced Intensity Alternative <br />Potential vibration impacts would be similar to the Proposed Project and would <br />be less than significant. <br />Alternative 4: IN peline Design Alternative <br />Potential vibration impacts would be similar to the Proposed Project and would <br />be less than significant. <br />Mitigation Measures <br />No Mitigation measures required <br />Level of Impact <br />Alternative 1: No adverse impact <br />Alternative 2: Less than significant adverse impact <br />Alternative 3: Less than significant adverse impact <br />Alternative 4: Less than significant adverse impact <br />Mid Basin Centennial Park �tc&njl <br />_ *Project Final EIR 5-216 <br />
