Eric, As I understand from Maxwell (through our engineer, Jonathan McCulley), Maxwell needs a cross-section of the channel at each of the bridges. After an extensive search, we cannot find appropriate drawings in any pertinent set (Phase 1B, 1C, or 1D) that shows the cross-section with meaningful dimensions or elevations. Regardless, since Halff didn't provide those designs, we wouldn't have the authority to send those drawings to Maxwell. Unless UDR or the Town has access to addition documents, it would seem that Icon alone will be able to provide Maxwell what he requires. Regards, Eric C. Eric S.

We need the cross section so that we can perform global slope stability analyses. Let me know if you have any questions. Thanks! Wei Zhang, P.E.
