USACE Activities 11

Risk Informed Inspections and AssessmentsRisk 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 R

igor, Effort

Continuous Feedback

Page 12: USACE Levee Safety Program Presented by Tammy Conforti ASFPM Conference May 2008

USACE Activities 12

Levee Inspection ProgramLevee 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 Certification ETL (EC)Levee Certification ETL (EC)

Implementation concurrent with field reviewComment period completeFormal ITR and peer reviewHighlights –

•Systems based, no “partial” certifications•10-year validity period•Addresses residual risk•Requires LCR•Will be updated to reflect advances with risk-based approaches

Page 17: USACE Levee Safety Program Presented by Tammy Conforti ASFPM Conference May 2008

USACE Activities 17

Vegetation StandardsVegetation 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.

National Levee Safety ActNational 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
