Additionally, this section is <br />updated to indicate that if any seeps are encountered during building pad preparation, we should <br />be consulted regarding additional underdrains within the building pad to manage seepage. <br /> <br />Section 7.1 <br /> <br />This section is updated to indicate that potential displacement of up to 4 inches could occur due <br />to secondary fault displacement. To reduce the impacts of ground offset due to fault -induced <br />ground deformations, we recommend that isolated footings be conne cted with either grade beams <br />or ties designed for the strength requirements in Section 12.13.7.2 of ASCE 7 -16. <br /> <br />Section 9.3 <br /> <br />This section is updated to refer to Section 6.5 in lieu of Section 4.5. <br /> <br />Section 10.3 <br /> <br />This section is updated to refer to Section 6.5.1 in lieu of Section 4.5.1. <br /> <br />Section 11 <br /> <br />This section is updated to refer to Section 3 in lieu of Section 1.3. <br /> <br />If you have any questions or comments regarding this letter, please call and we will be glad to <br />discuss them with you. <br /> <br />Sincerely, <br /> <br />ENGEO Incorporated <br /> <br /> <br /> <br /> <br />Jeff Fippin, GE Daniel S.
