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…
