O38 Email from Nov 13 2025 to Dec 9 2025 between Mr Kleinberg and Mr Seele

including radius of influence on the analysis sections. Alejandra Mazier will be out Monday through Wednesday and begin reviewing anything you have sent over when she returns. As we discussed we are surprised that the analysis for seepage parallel to the slope would yield a FS on the order of 1.5. We agree that that would be an extreme event which may justify a lower Factor of Safety upon review of relevant standards. We agree that the Hazus mapping likely corresponds to the Feltville sandstone and disintegrated sandstone. As we mentioned in our report that this may begin near Langan Borings LB2 and LB4. Unfortunately neither we nor Langan have been able to locate a report describing the mechanism of the slope mode of failure on which they identified the area of the hazard. In closing we understand that you both did not take any exception to the recommended conditions of approval included in our report. If you need to contact us, you can contact Nelson Hernandez and/or Alejandra Mazier. | hope everyone has a wonderful thanksgiving.
