2Levee Safety
- is the art and science of ensuring the integrity
and viability of levees such that they do not
present unacceptable risks to the public,
property, and the environment
West Columbus, Ohio
3National Levee Safety Program
- Background
- USACE Flood Damage Reduction mission began with
the 1917 Flood Control Act - Significant Role in flood activities nationwide
to include the protection of life and property
behind federal levee systems. - Hurricane Katrina and Rita devastation in 2005
brought levee safety to the forefront of public
awareness - Findings of investigations into flood damage
reduction systems performance in New Orleans
prompted the need for a comprehensive and
risk-informed approach to national levee safety,
including periodic assessments.
4Graduated Levee Assessments
Robust Levee Safety Program
Routine Inspections Verifies OM, More Rigorous
Standards, Improved Communication, System-based,
Every Year
Continuous Feedback
Periodic Inspections Verifies OM, Evaluates
Structure Stability, Compares Constructed
Criteria to Current Criteria, Every 5 Years
Increasing Rigor, Effort

- Engineering Technical Letter (ETL) No. 1110-2-571
Guidelines for Landscape Planting and Vegetation
Management at Levees, Floodwalls, Embankment
Dams, and Appurtenant Structures. - This ETL does not establish new standards, but
clarifies, and supersedes, those formerly
presented in EM 1110-2-301 (Jan. 1, 2000). - Key Points
- Fifteen feet is the minimally accepted vegetation
free zone (VFZ) and is widely viewed as not
sufficient for all projects. To date, no
research exists to justify a reduction to
existing standards. - If an existing project easement (real estate
interest) allows for less than 15 feet, the VFZ
shall be the maximum attainable within the
existing real estate interest. - The ETL discusses a limited range of conditions
under which a variance to vegetation standards
may be granted. The variance request process is
currently under revision and interim guidance is
available through the HQUSACE Levee Safety
Program Manager (LSPM). Public safety will not
be compromised. - The standards in the ETL are not new, and USACE
has considered them critical to flood damage
reduction project reliability for decades. - The ETL is available at http//140.194.76.129/pub

10National Levee Safety Program - Current Activities
11National Levee Safety Program Current Activities
- AMERICAN RECOVERY AND REINVESTMENT ACT OF 2009
Periodic Inspections of Levees - 90 Million nationwide
- Opportunity to leverage stimulating the economy
through the use of the private sector contractors
to accomplish Periodic Inspections with obtaining
much needed information about the levee
infrastructure throughout the nation. - The activity will assist in aggressively
advancing the Levee Safety Program toward
achieving its goal of reducing flood risks and
improving public safety. - Complete execution of activities by September 30,
2010. - All levees in federal levee program including
inactive levees
12National Levee Safety Program Current
Activities The Levee Screening Tool
- The Levee Screening Risk Assessment (LSRA) Tool
(Microsoft Excel Spreadsheet) provides a
preliminary assessment of the general condition
and associated risks of levee segments and
systems in support of the USACE Levee Safety
Program. - Routine inspection data will be combined with a
preliminary engineering assessment to indicate
the ability of a levee system to perform as
intended and the consequences of potential
failure. - The LSRA determines a preliminary relative risk
index that will consider routine inspection
results and ratings coupled with a review and
evaluation of historical performance data,
as-built drawings, economic and life loss
consequences, historic and current hydraulic and
hydrology data, and other data. This will help
determine the potential for failure and the
consequences of failure.
13National Levee Safety Program Current
ActivitiesNational Levee Database Surveys for
Tulsa District
- Congress directed the U.S. Army Corps of
Engineers (USACE) to develop a national levee
inventory to locate and document the status of
levees under Federal jurisdiction. A cornerstone
of this effort is the National Levee Database
(NLD). - Contractor, PBSJ, will survey levees this
summer, fall and winter in federal program to
collect detailed survey information on the levee
without any cost to the city/county. This survey
information is being collected for the NLD and
will be shared with you after it is finalized and
quality assurance checks have been completed.
