1 BUILDING STRONG ® 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 rating. 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 US Army Corps of Engineers BUILDING STRONG ® Name of Levee Segment Presenter Name Presenter Title Duty Location Date of Presentation

3 BUILDING STRONG ® 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 BUILDING STRONG ® Location Map/Overview

5 BUILDING STRONG ® Vicinity/Segment Map SEE EXAMPLE, NEXT SLIDE

6 BUILDING STRONG ® Vicinity/Segment Map

7 BUILDING STRONG ® Summarize Hydraulics Use 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 BUILDING STRONG ® Summary of Hydraulics  Authorized Capacity Frequency - xxx yr return period  Overtopped: No / Yes  Failured: No / Yes  Times Loaded (events) 25% - xx 50% - xx 75% - xx 10 year return 1000 year return Record Flood 66% of height

9 BUILDING STRONG ® Performance History

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

11 BUILDING STRONG ® Typical Sections Levee Embankment Elev ft15ft Riverside Landside Toe Elevation Approx Crest Height:xx-xx Ft Crest Width: xx Ft Foundation Geology: Levee Materials /Zoning: Riverside Erosion Protection:Sod/Riprap

12 BUILDING STRONG ® Typical Flood Wall Section

13 BUILDING STRONG ® Typical Section with Culvert

14 BUILDING STRONG ® Example: Culverts/Closure

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

28 BUILDING STRONG ® Major Contributors to Overall Risk Rating

29 BUILDING STRONG ® Major Contributors to Risk Prior to Capacity Exceedance

30 BUILDING STRONG ® Segment Ratings Compared to All Segments

31 BUILDING STRONG ® Performance Index vs LOL

32 BUILDING STRONG ® Performance Index vs Economic Damages

33 BUILDING STRONG ® Recommended LSAC Rating  Prior to Capacity Exceedance LSAC = xx  Capacity Exceedance LSAC = xx  Recommended LSAC = xx  Add Reasons for adjusting LSAC rating
