  • Slide 11
  • USACE Activities 11 Risk Informed Inspections and Assessments Continuous Routine Inspections by Sponsor - More Rigorous Standards & Checklist 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) Pre-Screening Based on Inventory Results - Prioritization of Periodic Assessments And Risk Assessments Increasing Rigor, Effort Continuous Feedback
  • Slide 12
  • USACE Activities 12 Levee Inspection Program Routine Inspection: Verifies proper operation & maintenance activities conducted by the public sponsor. Periodic Inspection: Verifies proper operation and maintenance and evaluates structures 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.

  • USACE Activities 16 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
  • Slide 17
  • USACE Activities 17 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.
