USACE Inventory and Assessment
Objective: Assess all levees in USACE
programs, regardless of level of
protection.
Levee Categories
WRDA Authorities
Objective: Inventory all levees in nation, lead strategic
plan for a National Levee Safety Program

USACE Activities 7
National Levee Database
(NLD) and Inventory
One Geospatial Database Model
Collect Relevant Levee/Floodwall Attributes
• Design and construction
• Operations and maintenance
• Repair and inspections
• Potential for failure
Maintained by Districts; Accessible by Others
FEMA Mid-Term Levee Inventory Data Collected
Using USACE Database Model & Structure

USACE Activities 10
Risk Informed Inspections
and Assessments
Continuous Routine Inspections by Sponsor
- More Rigorous Standards & Checklist
Pre-Screening Based on Inventory Results
- Prioritization of Periodic Assessments
And Risk Assessments
Annual Robust Inspections by District
- Professionally Managed
Periodic Assessments
- Periodic Inspection + Screening Risk Assessment
(every 5 years)
Risk Assessments - Rigorous, data intensive
effort (every 10 years)
USACE Activities 11
Levee Inspection Program
Routine Inspection: Verifies proper operation &
maintenance activities conducted by the public sponsor.
Periodic Inspection: Verifies proper operation and
maintenance and evaluates structure’s operational
adequacy, structural stability and identifies components and
features that the sponsor needs to monitor over time.
Periodic Assessment: Combination of PI and potential
failure mode and consequences analysis used for initial
screening and prioritization of RA.
Risk Assessment: Process of identifying the likelihood and
consequences of levee failure to provide the basis for
informed decisions on a course of action.

Levee System Inspection
Automated Field Components
• USACE Levee System
Inspection Application
• ArcGIS Software
• Crystal Reports
(Included with
ArcGIS)
• Laptop Computer
or Tablet PC
• GPS Receiver
USACE Activities 14
Risk Assessments Outcomes
Levee Safety Action Classification
Consequences
• Relative Annualized Loss of Life
• Relative Economic Damage
• Others, environmental, etc
Component Risk – What is driving risk
Information on data quality and gaps
Issues that influence certification
Documentation of confirmed failure modes
Recommended risk management actions
USACE Activities 15
Levee Certification ETL (EC)
Implementation concurrent with field
review
Comment period complete
Formal ITR and peer review
Highlights –
• Systems based, no “partial” certifications
• 10-year validity period
• Addresses residual risk
• Requires LCR
• Will be updated to reflect advances with riskbased approaches
USACE Activities 16
Vegetation Standards
Vegetation policy development includes four
steps Review standards and vegetation management
policy using current engineering and science.
Conduct an external peer review of standards.
Identify related regulations and policies that
require modifications to implement the new
vegetation management policy. Create an
implementation plan.
Conduct national roundtable to discuss
updated policy, standards, and implementation
plan.
USACE Activities 17
FY 2008 Inspection
