9. What and Why Are We Scoping? Information Search Coordination / Outreach Assess Community Mapping Needs

10. Map Modernization 1834 Style (Pre-FIRM)

11. Map Modernization 2007 Style DFIRM Product

12. Overall Scoping Study

13. Scoping Activities

14. Pertinent Data on Kaufman County Area = 787 Sq. Mi. Density = 108 Persons/Sq. Mi.

15. Pertinent Data on Kaufman County 22 Effective FIRMs (Printed) Scales: 1”= 2000’ Average Panel Age = 15 Years Flood Insurance Policies in Place = 108 Claims = 32 ($177,722) LOMC’s = 28

16. Kaufman County Re-Study Scoping 57 miles of Detail Study (Zone AE) 567 miles of Approximate Study (Zone A) 30 Proposed FIRMs

17. The Study Process Information Search Base Map and Terrain Data Acquisition Field Survey Hydrology Hydraulics Mapping Reporting (TSDN) Coordination /Outreach

18. Local Provided Planimetrics USDA National Agricultural Imagery Program (NAIP) USGS Contours Supplemented with Local Data Base Mapping

19. Terrain Map Sources Local Data USGS Contour Maps & 30 M DEMs LiDAR Formats Digital (GIS Shapefiles, AutoCAD Files) Hardcopy Terrain Information

20. The majority of existing FIRM panels vertical datums: National Geodetic Vertical Datum (NGVD) 29 Local Datum New DFIRM Panel datums will be standardized to: Vertical - North America Vertical Datum of 1988 (NAVD 88) Horizontal – North American Datum of 1983 (NAD 83) DATUM – NAVD 88 / NAD 83

21. Possible Mapping Products Available New Detailed Study Enhanced Approximate Study Redelineation of Existing Detailed Study Approximate Study (Zone A Refinement) Digital Conversion

22. New Detailed Study Field Survey New Topo/Orthophoto Detailed Hydrologic and Hydraulic Modeling Floodway Computations Flood Profiles Calibrated to Historical Events Most Expensive Type of Study

23. Enhanced Approximate Study Limited Detailed Study No (or) Limited Structure Surveys No (or) Limited Floodways No (or) Limited Profiles Advantages Cost is Much Less Than Detailed Study More Streams Can Be Studied

24. Redelineation Streams Applies to Existing Detailed Study Streams (Zone AE) Vertical Datum Update from 1929 to 1988 Flood Boundaries Mapped to the Best Available Topography

25. Zone AE Redelineation

26. Approximate Study Zone A Refinement Automated H&H Procedures Boundaries Mapped to Best Available Topography

27. Sample of Existing Zone A

28. Zone A Refinement

29. Digital Conversion Utilize the Existing Flood Zone Information Advantages: Low Cost Solution Disadvantages: Boundaries may not agree with the best available topographic data

30. Incorporation of Existing Data Studies The study represents an improvement to the current effective study, but it is not a substitute for a LOMR. The study includes the 10-, 50-, 100-, and 500-year flood frequencies and floodway for existing hydrology. The study includes complete and accurate technical documentation (topography, field surveys, horizontal and vertical datum, bridge data, “as-built” plans, digital workmaps, digital hydraulic and hydrologic models, LOMRs, etc.) The study incorporates all known LOMCs. Tie-ins between the effective and proposed mapping and profiles are seamless. The proposed mapping should be geo-referenced or easily referenced to a known coordinate system. The study is signed and sealed by a registered Professional Engineer. The community certifies in writing that the study information has been formally reviewed and approved. The study complies with all community ordinances. The study can be defended by the City during the appeals period, and shall assume financial responsibility, if necessary, that may arise as a result of including the study in the DFIRM. During this Scoping Meeting you will be identifying your communities needs and identifying what existing information, if any, your community has with regard to the hazards. Once we have that information – a detailed schedule will be developed in the next few weeks. This information will be provided to FEMA for negotiation and approval. The map adoption phase will take approximately ____ to ____ months. Overall, this entire process will be a ____ to ____ month process. FEMA has committed $_______________ for the development of DFIRMs for _____________ County. This mapping product will be a Countywide which will include all unincorporated areas and all incorporated communities.

40. 40 Levees: Protection with Risk Levees are designed to provide specific level of protection They can be overtopped or fail in larger flood events They require regular maintenance and periodic upgrades to retain their level of protection FEMA urges people to understand their flooding risk involving levees

41. 41 Levee Ownership FEMA does not own, operate, maintain or certify any levees FEMA can accredit a levee certification provided by others The levee owner can certify the design, construction, operation and maintenance of a levee Certification is responsibility of the community that is benefiting from the levee

42. 42 FEMA’s Certification Requirements FEMA’s accreditation requirements are contained in 3 documents. A. Certification Standard is 44 CFR 65.10 Specific requirements for Levee Design, Construction, Operation and Maintenance Certification checklist is based on requirements from 44 CFR 65.10. Revised date is October 1, 1999. B. Procedure Memorandum No. 34 (PM 34) Certification Documents are available to submit within 30 days. “Interim Guidance for Studies Including Levees” August 22, 2005 C. Procedure Memorandum No. 43 (PM 43) “Provisionally Accredited Levee” Need time to gather certification documents-24 months allowed. “Guidelines for Identifying Provisionally Accredited Levees” September 25, 2006 Revised March 16, 2007

43. 43 44 CFR 65.10 Highlights To be certifiable, the levee system must be owned and operated by a public entity The levee owner has the ultimate responsibility of certifying the levee Design and Construction requirements Freeboard, Foundation, etc. Operation and Maintenance requirements O&M manual, maintenance records, etc. Federal Agency (USACE) who constructed levee can provide certification Levee must be certified/re-certified every time the map is changed

44. 44 PM 34 Highlights Interim guidance to establish certification process (flowchart) Specifies that levee systems that are mapped by FEMA are designed, constructed, operated and maintained to standards (44 CFR 65.10) Requires obtaining verification that certification requirements are and continue to be met Requires that necessary certifications are provided by the responsible party

45. 45 PM 43 Highlights Created to prevent levee issues from holding up DFIRMs Allows 2 years to compile certification documentation Not allowed for any levee that requires any construction work to be done for certification Public versus Privately owned levees (PAL Scenario) PAL Agreement

46. 46 Levee Checklist

47. 47 FEMA Accreditation of Certification If adequate certification is provided and accepted, FEMA will accredit the levee as providing protection If levee certification is not provided, the area will be mapped with the levee NOT providing protection

48. 48 Presentation of Preliminary DFIRM to Community (also known as CCO Meeting) 90-Day Appeal Period Appeal Resolution Letter of Final Determination (LFD) 6 Month Compliance (Map Adoption) Period Final adoption and/or revision of Floodplain Management Ordinance Effective DFIRM
