USACE Post-Hurricane Monitoring requirements Post-storm assessments of Corps Projects Damage estimates (economic & engineering) Extreme event data – forensic storm analysis – High Water Marks and storm surge hydrograph – Wave observations, including over land – Used for model development/evaluation Most information is time-sensitive, need it quickly – Presents funding and other agency/contracting challenge

Questions What works now with respect to interagency post- storm assessment activities? Do you know what the other agencies are doing? Are you aware of duplication of efforts? What can be improved? How can a workgroup a with high-level representation help our folks in the field? Summarize your 2008 post-storm activities (Ike, Gustav, etc). Describe 2009 plans. Are you interested in the plans of the other agencies?

Summary Comments Received Lots of data being collected – need shared data dump: federal, state, local Need maximum wind speed map along track (immediately afterward) – based on observations and radars, NWS, TV, airports, etc FEMA/Corps coordination could be improved Also some discussion is warranted on the optimal time to do post-storm beach surveys for various purposes: FEMA requires surveys to assess how much help a beach should be awarded based on sand loss. If the survey is done too soon, before natural recovery, the assessment may overestimate sand loss. If post-storm LIDAR happens too late, then the storm effects and natural recovery can no longer be separated from everyday sediment processes. It would help to have: – a measure of the beach width before a storm; – a measure of the berm width after the storm; – location of vertical erosion damage indicators (0.5, 2.0, 4.0 ft) with respect to structures – Associated structure damage.

2008 Activities (incomplete) Jacksonville District assisted FEMA in post- storm beach assessments around Florida and into North Carolina during LIDAR surveys – coordinated with USGS, NOAA, NAVY, NASA Street-level real-time ADCIRC forecasts for the New Orleans district during Gustav – Intense, tiring, technically challenging, useful

2009 Plans (incomplete) Fly the coast, send out teams to inspect the projects before and after the storms. etc..... Concerns Funding – Affects our level of involvement – Can OFCM still accumulate funds for post-storm use? Rapid access to other agency/contractor data is important to our post-storm efforts/reports/preparations

Post-meeting plans Build internal/external lists – HQ, district, laboratory POCs – Agency contacts Convey out meeting results Serve as POC from USACE to other agencies during the season, as needed Keep engaged
