This information is included in Appendix – <br />Construction Information. We understand that no piling driving will take place during construction. <br />Vibration from both on-site construction equipment and truck routes were evaluated. The truck routes <br />run between I-580 and the project site along Foothill Road, Laurel Creek Way, and Stoneridge Mall Road <br />(South). <br />Table 2 and Table 3 provide a summary of the estimated vibration levels to off-site sensitive receptors <br />from construction activity and compares the results to the limits set forth in the SEIR. As shown in the <br />tables, the vibration caused by on-site construction equipment and trucks along the truck route will not <br />exceed the limits from Table 4.J-4 of the SEIR. <br />Additional Measures <br />None required.
