    Presentation Transcript
    1. Do not include this Slide. This template is a guide for preparing power points presentations. The information requested is important and should be provided in generally the same sequence and same format. But each presentation must be tailored for the specific segment being presented. Some slides can be eliminated and sometimes extra slides will be necessary to best convey the background and backup data needed to make the case for the LSAC assignment. Pictures are generally a very good method for communicating information on a particular feature or defect being evaluated. Some of the additional summary type slides will eventually be produced directly from the LST but until then you will have to cut and paste the data / graph into the power point. Adjust font size, color, layout, tables, etc. as needed to improve the presentation. Do not overload your slides with too much information; It is better to add a slide. Don’t be surprised to see future revisions to the Power Point. The power point for the SOG will likely be a subset of this power point.

    2. Presenter Name Presenter Title Duty Location Date of Presentation Name of Levee Segment

    3. 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 (year) • Population at Risk

    4. Location Map/Overview

    5. Vicinity/Segment Map SEE EXAMPLE, NEXT SLIDE

    6. Vicinity/Segment Map

    7. Summarize HydraulicsUse graphics on following slide to present information • 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

    8. Summary of Hydraulics 1000 year return • Authorized Capacity Frequency - xxx yr return period • Overtopped: No / Yes • Failured: No / Yes • Times Loaded (events) 25% - xx 50% - xx 75% - xx Record Flood 66% of height 10 year return

    9. Performance History

    10. Geomorphology / Foundation Geology • Present typical foundation / subsurface conditions in longitudinal profile and or cross sections to document section being assessed.

    11. Typical SectionsLevee Embankment Riverside Landside Elev. 718.7 ft 15ft 3.0 4.0 1.0 1.0 Toe Elevation 703.0 Approx Crest Height: xx-xx Ft Crest Width: xx Ft Foundation Geology: Levee Materials /Zoning: Riverside Erosion Protection: Sod/Riprap

    12. Typical Flood Wall Section

    13. Typical Section with Culvert

    14. Example: Culverts/Closure

    15. Review/Compare ICW Rating with LST Rating in Table format Highlight Primary Factors and other indicators needing attention / discussion. Review of Assessment Ratings Use table format similar to that shown on following slides. ADJUST TABLE COLUMN WIDTHS AS NEEDED

    16. EMBANKMENT SEEPAGE SUPPORTING PHOTOS

    17. Embankment Seepage Assessment Ratings

    18. EMBANKMENT STABILITY SUPPORTING PHOTOS

    19. Embankment Stability Assessment Ratings

    20. FLOOD WALL SEEPAGE SUPPORTING PHOTOS

    21. Flood Wall Seepage Assessment Ratings

    22. FLOOD WALL STABILITY SUPPORTING PHOTOS

    23. Flood Wall Stability Assessment Ratings

    24. CULVERTS AND CLOSURE SUPPORTING PHOTOS

    25. CULVERTS AND CLOSURE ASSESSMENT RATINGS

    26. Consequence Data Summary • Weighted Fatality Rate xxxx • Threatened Population w/o warning xxxx • Estimated Loss of Life w/o warning xxxx • Number of structures Inundated xxxx • Economic Damages $xxxxxx • Critical Infrastructure / Environments

    27. Assessment Rating SummaryPrimary Factors Embankment & Foundation Seepage - U,M,A Embankment Stability - U,M,A Erosion - U,M,A Closure System - U,M,A Flood Wall Stability - U,M,A Flood Wall Under Seepage - U,M,A

    28. Major Contributors to Overall Risk Rating

    29. Major Contributors to Risk Prior to Capacity Exceedance

    30. Segment Ratings Compared to All Segments

    31. Performance Index vs LOL

    32. Performance Index vs Economic Damages

    33. Recommended LSAC Assignment • Prior to Capacity Exceedance LSAC = xx • Capacity Exceedance LSAC = xx • Recommended LSAC = xx • Add Reasons for adjusting LSAC assignment
