Title: Southeast Louisiana Flood and Hurricane Protection Current Status
1Southeast LouisianaFlood and Hurricane
Protection Current Status
- Briefing by Headquarters US Army Corps of
Engineers for - Subcommitee on Hydrology
- 12 January 2006
2Topics
- Status of Reconstruction Efforts
- Recent Funding and Reconstruction
Guidance/Direction - Interagency Performance Evaluation Team
3Background
- 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
4Challenges
- No Flood Fighting During the Event!
- Security Concerns
- Communication Obstacles
- Atypical Flooding no drainage
- Lack of Access
- Data Scarcity
- Information Crush
5Today Recovery from Katrina and Rita Continue
- Summary as of 28 December 2005
- Corps personnel deployed 1,734
- FEMA mission assignments 4,401,167,000
- Temporary roofs 209,211 completed
- Water 4,979 truckloads ordered/distributed
- Ice 5,276 truckloads ordered/distributed
- Generators installed 910 (Kat Rita)
de-installed 910 - Debris 33, 066,429 CY removed 51,240,000 CY

9Status 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
10Current 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.
11System Flooding
12Requirements 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

18Modeling 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
19Incorporation 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
20The 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
