Benefit to cost ratio analysis is currently under way by the USACE. NorthWest Hydraulics (NHC) is currently studying the potential impacts of these alternatives on flood area, depth and duration for flood events of varying sizes. The evaluation of all four LRPs will be included in the GRR/EIS that is currently being developed. The local sponsors will inform the broader community of the progress on these efforts and provide opportunities for input at strategic intervals.
The preliminary results will be available by the end of 2010.
The local sponsors and community are working with the USACE to point out where benefits of this alternative are under estimated, including:
If identified benefits can be increased, then 2A could become eligible as an LPP.
