  Engineers for
• Subcommitee on Hydrology
• 12 January 2006

Background

• 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

Challenges

• No Flood Fighting During the Event!
• Security Concerns
• Communication Obstacles
• Atypical Flooding no drainage
• Lack of Access
• Data Scarcity
• Information Crush

Status of Funding for Repairs

• Reference news conference of Thursday, 15 Dec 05
• 1.6B Restore Previous Levels of Protection
• 1.5B Additional Safety Security Measures
• Reconciling Scope of Work Issues and Priorities

10
Current Conditions

• Damaged and/or Breached Federally constructed
  levees and floodwalls.
• Floodwalls and levees with minor damage that have
  settled below design grade.
• Damaged non-Federal pump stations, other flood
  control works and levees.

11

Requirements for Achieving Authorized Level of
Protection

• Authorized level of Protection
• Repair and raise Federal projects to current
  design grade (incorporation IPET findings)
• Repair Federally built or modified Pumping
  Stations
• Repair non-federal pumping stations and levees

Modeling Hydrologic Conditions

• 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

19
Incorporation of IPET 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

20
The 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
