Levee Overview USACE District Name of Segment Identify Segments relationship to Levee System (Does
Segment = System, or is it only a part of a bigger system.) Segment ID from NLD Name of water course/river/creek Authorization / Project Identity of Owner Operator Dates of Construction Type of Presentation- MSC/National QA/SOG
BUILDING STRONG®
Location Map/Overview
Label state, region, major cities. Identify critical infrastructure or special
environmental concerns.
In Notes: Add details of location, length, description of protected area (rural/urban/industrial).
BUILDING STRONG®
Vicinity/Segment Map
Figure with protected area polygon overlaid on google map/Corpsmap.
Identify location and number of embankment sections, floodwalls, pump stations, major culverts / penetrations, and protected area # of closures. [levee – brown line, floodwall – black line, pump station or culvert – orange dot,
BUILDING STRONG®
Geomorphology / Foundation Geology
Present typical foundation / subsurface conditions in longitudinal profile and or cross section.
BUILDING STRONG®
Typical Sections
Embankments, floodwalls, major culverts and other pertinent features
Label height, crest/top width, slope angles, drainage features, seepage barriers/cut off walls, etc
BUILDING STRONG®
Summarize Hydraulics Frequency top of levee/floodwall or show on
typical sections Frequency toe of levee/floodwall or show on
typical sections Identify frequency of event that results in poor
performance/history of problems Summarize loading history – flood of record plus
other major flood events
BUILDING STRONG®
Performance History On Segment Map show area/ reaches with
major seepage, boils, instability, flood fighting, overtopping, erosion, etc.
Indicate % of height of the levee / floodwall/culvert at which problems start to occur.
May be able to capture some or all of this information on previous slide otherwise show it here

ICW Ratings
Include date of Inspection, date of Screening and who performed these tasks (AE/Corps/Others)
Short summary of ICW inspection and any issues noted
BUILDING STRONG®
Review of Assessment Ratings Review/Compare
ICW Rating with LST Rating in Table format
Highlight LST ratings that are M or U.
BUILDING STRONG®
Major Contributors to Overall Risk Rating
Focus discussion on selected items that were deemed Unsatisfactory and that are major contributors to the overall risk / rating. Include enough background data/documentation, and justification to make the case. Provide photos as additional slides that support the rating.
BUILDING STRONG®
Example: Culverts/Closure If multiple culverts/closures are associated with
project, the logic behind which one was rated should be provided by the LST Facilitator
Embankment culvert selected and why * What was used to assess the culvert? Existing
condition, supplemental tool, etc… Floodwall culvert selected and why * What was used to assess the culvert? Existing
condition, supplemental tool, etc…
