... All meetings included presentations from IPET staff, the Corps of Engineers, and other invited experts; public comment sessions; and, closed sessions in which the committee discussed the IPET reports and its own draft reports. The IPET and Corps of Engineers provided an extensive amount of information to this committee in those meetings, which was essential to the committee's education and to allowing it to provide informed feedback to the IPET.

... Pink and blue shading indicates areas that flooded; blue-striped areas are wetlands. Starts indicate levee breaches or distressed levee areas; circles indicate pumping stations.
From page 10...
... The report included multiple recommendations for more thorough data gathering and testing of soil properties across the system. It also recommended that the IPET adopt an ensemble approach -- reflecting a range of possible storms and storm surges -- in its hurricane modeling exercises.
From page 11...
... Further advice on soils sampling and testing measures was included: it recommended that the IPET present site plans and soil profiles at breach sites, that clay and marsh deposit strengths be estimated at locations other than the 17th Street Canal, and that IPET provide additional guidance for identifying erodible soils, quantifying the degree of soil resistance to erosion, and selecting and placing soils to resist erosion. The report noted that although the IPET risk analysis approach was coherent and logical, that the levels of uncertainty in estimates of risks in flooding were expected to be large.
From page 12...
... It also recommended that the IPET issue a set of inundation maps that displays best estimates of inundation depths for 50-year, 100-year, and 500-year event recurrence intervals. The report further recommended that the modified joint probability model employed in Volume VIII be fully and clearly explained in a single place within the report, as opposed to partial explanations that were listed in multiple, separate sections.
