CAG January 12, 2023 Meeting

Thursday, January 12, 2023 4:00 PM - 6:00 PM


The meeting was live streamed on YouTube.
Information about the underwater survey has been amended as follows. 

Survey work will occur in-water and data collected will be used to inform multiple disciplines on the IBR team. For cultural resources, in accordance to National Historic Preservation Act’s Section 106, the IBR program will be using the underwater study information to identify any potential underwater historic properties that could be impacted by the IBR program. For the design team, the information will be used to do hydraulic modeling to understand how the bridge foundations will affect the water flow in the river. The structures team will use it for designing the bridge foundations.

After the initial data is collected from the study, areas that need further investigation will be identified. Findings from the underwater study will be available in the Supplemental Draft Environmental Impact Statement (SDEIS), released for public comment in 2023.
