BackgroundBackground

• Hurricane damaged approximately 64% of the system.

• ASA(CW) approved one time deviation from policy to under take permanent rehabilitation of federal and non-federal projects at full federal expense using FCCE funds & fund acquisition of lands, easements, rights-of-way, and disposal or borrow areas needed for rehabilitation.

• Restoration of damaged federal protection systems by 1 June 2006

Modeling Hydrologic Modeling Hydrologic ConditionsConditions

• Coordinated Effort Between USACE, USGS, NOAA, and FEMA

• Considerations:– Understand Storm Events Much Better– Improved Techniques and Technologies for

Prediction– Changed Physical Environment– Level of Rigor:

• Initially Rudimentary• Increasingly Rigorous as Input Data

Improves



UNCLASSIFIED

Incorporation of IPET Incorporation of IPET Results (to date)Results (to date)

• Strengthening of transition zones where levees and floodwalls abut – longer transition zones, hardened scour zones, deeper piles

• Revise floodwall designs – Replace I wall with T or L wall

• Harden surfaces susceptible to scour• Harden surfaces around points where

pipelines penetrate levees



UNCLASSIFIED

The Path AheadThe Path Ahead

• Congressional Briefings• Interim Levels of Protection Dec 05• Complete Repairs to Levees to Pre-Storm

Conditions Jun 06• Uncertainties:

– Upgrades to Levels of Protection?– Supplemental?– Coastal Policy?– Levee Portfolio?

• Conduct System Performance Analysis
