USACE Levee Safety Program Presented by Tammy ConfortiASFPM Conference May 2008
Topics of Discussion • USACE National Levee Safety Program Organization • National Levee Database • Inspections • Recent Guidance • National Levee Safety Act 2007 • Websites
Levee Safety Program Mission Assess the integrity and viability of levees and recommend actions to assure that levee systems do not present unacceptable risks to the public, property, and the environment. West Columbus, Ohio • Hold Public Safety Paramount • Reduced Economic Impacts • Maximize Cost Effectiveness • Develop Reliable and Accurate Information • Build Public Trust and Acceptance Program Objectives:
Implementation Guidance • Issued to field in November • Establish Levee Safety Officers • Establish Levee Safety Program Managers • Submit plans for organizational structure • Use revised inspection checklist • Describes the different tiers of inspections • Provides guidance for inspection intervals • Announces training for the inspection tool • Informs of future NFRMP guidance

FEMA NFIP Objective: Communicate the most current information for flood insurance purposes. NFIP & CORPS NFIP only 100-year Federal O&M USACE built / Local O&M Local built / Enrolled in RIP Local & Other No Prior Nexus with USACE or FEMA Level of Protection CORPS only 1 2 3 4 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 Universe of Levees New Nexus from WRDA 2007 Area represents all levees throughout the US. USACE Dec07 Not to scale
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
Database Viewers Database Viewers What will database and national web viewers look like? Main viewer will be CorpsMap Other viewers could include Google Earth

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 Continuous Feedback Annual Robust Inspections by District - Professionally Managed Increasing Rigor, Effort Periodic Assessments - Periodic Inspection + Screening Risk Assessment (every 5 years) Risk Assessments - Rigorous, data intensive effort (every 10 years)
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 InspectionApplication • ArcGIS Software • Crystal Reports (Included with ArcGIS) • Laptop Computer or Tablet PC • GPS Receiver
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
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 risk-based approaches
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.
FY 2008 Inspection Priorities • Priority 1 – Complete I-Wall Evaluations • Priority 2 – Routine Inspections • Priority 3 – Automated Inspection Tool Training • Priority 4 – Vertical Datum Evaluations • Priority 5 – Coordination with FEMA on PALs • Other Activities – HQUSACE Approval • No inspection funds will be allocated to perform certifications
USACE Support-Floodplain Management Services Program • Can provide support for levee certification determinations for others to certify • Support activities can include • Data Collection • Mapping • H&H Analyses • Geotechnical Investigations • 100 Percent Federally Funded, If Available
Floodplain Management Services Program (Cont’d) • USACE can accept voluntary contributions from State or local government to expand scope • USACE cannot certify levee systems under this program
National Levee Safety Act • Establishes a Committee on Levee Safety to develop and recommend a program to the Secretary and Congress • The program must address nine goals, including consideration of delegation to qualified states • Establishes a levee database (all levees) to be maintained by the Secretary • Levee inspections for the Act are to be cost-shared • Authorizes $20 million annually for 2008-2013
Background on WRDA 2007 National Levee Safety Act • Complements Existing Activities & Authorities • Two Major Components: • A Strategic Plan, Not a Program • Safety Data Collection • “One Time” Nature • Levees Include: • Hurricane, Storm & Flood • Structures: • Earthen embankments • Floodwalls • Structures along canals
