In a "Draft Wave Modeling Summary" (dated Aug. 28, 2018), the Corps of Engineers states:

The purpose of this brief is to provide a summary of the surface wave modeling results. Only two breakwater modifications will be presented and does not include additional defensive measures that must be incorporated to provide a similar level of protection as the current breakwater configuration. This work is preliminary and may contain errors and omissions. The full coastal engineering analysis will be included in the integrated feasibility report (IFR) to be released at a later time. Only results will be presented and no analysis will be made based on the modeling results in this overview.

Two modifications will be part of a forthcoming COE EIS/EIR (inviting public participation): one would remove the eastern 1/3 (roughly 4,450 feet) of the LB Breakwater; the other would produce two 1,000 ft. notches on the western half of the Brekwater.

The report notes: "Although reported in days/year for ease of communication, this value is actually a probability and events do not need to occur sequentially (i.e. 1 day of exceedance may consist of four separate events that last 6 hours each, 24 events that last for 1 hour, etc.)."
