USACE Post-Hurricane Monitoringrequirements

• 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

Email 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 2008.

• 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

Page 11: USACE Post-Hurricane Monitoring requirements Post-storm assessments of Corps Projects Damage estimates (economic & engineering) Extreme event data – forensic.

Post-meeting plans

• Build internal/external email 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
