1. NC Floodplain Mapping Program North Carolina Floodplain Mapping Program Becoming a Cooperating Technical State

2. NC Floodplain Mapping Program Background Overview of NC Floodplain Mapping Program Overview of the Assessment / Scoping Process for the six (6) initial River Basins Questions and Answers Wrap Up Topics for Today

3. NC Floodplain Mapping Program Background

4. NC Floodplain Mapping Program Needs / Limitations Identified Hurricane Floyd revealed data and map limitations FEMA program – North Carolina receives on average one updated Flood Study for one county per year Only 10-25% of flood hazards in county are evaluated ~ 55% of NC FIRMs are at least 10 years old

5. NC Floodplain Mapping Program Needs / Limitations Identified (continued) ~ 75% of NC FIRMs are at least 5 years old Many up-to-date maps are using 15-20 year old studies Many counties and communities have indicated that they do not have resources to take on responsibility

6. NC Floodplain Mapping Program FEMA Flood Insurance Rate Maps in North Carolina Mapped Areas 100 Counties 326 Municipalities Not Mapped 214 Municipalities

7. NC Floodplain Mapping Program Overview of NC Floodplain Mapping Program

8. NC Floodplain Mapping Program In response to these defined limitations, North Carolina has developed two strategies: Establishment of a statewide program to acquire, process and disseminate current, accurate, and detailed elevation data, flood studies, and maps. Establishment of North Carolina as a Cooperating Technical State (CTS) with FEMA.

9. NC Floodplain Mapping Program Program Deliverables Up-to-date maps (Flood Insurance Rate Maps) being provided to state and local officials (Study Basin by Basin) Up-to-date elevation data being provided to state and local officials (2 Feet or Less Vertical Accuracy /95%) Reduction of time needed for reviewing and approving proposed changes to FIRM maps (~6-7 months) Notification and dissemination of information about new and revised maps being provided to local governments, insurance agents, and citizens

10. NC Floodplain Mapping Program Program Deliverables (continued) On-going program for updating and maintaining FIRMs Post-event mitigation activities being better equipped and supported with timely updates to flood risk maps Interoperable GIS Dissemination of data and maps via the Internet Next generation information architecture E-gov Develop real time prediction of flooding

11. NC Floodplain Mapping Program Project Schedule 5 year statewide program 6 river basins completed by August 2002 3 river basins before September 2001 State approval of program August 2000

16. NC Floodplain Mapping Program Overview of the Assessment / Scoping Process for the first six River Basins

17. NC Floodplain Mapping Program What Is Scoping? Researching/inventorying available elevation, flood hazard, and digital base map data Assessing adequacy of existing flood hazard data Receiving input from counties and communities Determining best method to update flood data

18. NC Floodplain Mapping Program Identifying data needs (DEMs, cross sections, base maps, etc.) Determining proposed scales and paneling scheme for DFIRM production Establishing priority levels Developing schedule What Is Scoping? (continued)

19. NC Floodplain Mapping Program North Carolina will work closely with FEMA and FEMA’s Mapping Coordination Contractor, Dewberry & Davis LLC Process will involve 5 steps How Will Scoping Be Accomplished?

20. NC Floodplain Mapping Program State FEMA Kickoff Meeting with County/Local Floodplain Administrators Mapping Needs Assessment Effective FIS & FIRM Research Evaluate Post-Floyd Data NC Scoping Database Generate Initial Scoping Package Initial Scoping Meetings Develop Draft Basin Plans Final Scoping Meetings Finalize Basin Plans Process for Scoping Six River Basins in Eastern North Carolina Prepare Delivery Orders & CTC Mapping Activity Agreements & Update CTS Mapping Agreement Analysis and Mapping Step 1 Initial Research and Community Coordination Step 2 Initial Scoping Meeting Step 3 Draft Basin Plans Step 4 Final Scoping Meeting Step 5 Final Basin Plans SCOPINGPRODUCTION Questionnaire

21. NC Floodplain Mapping Program Today’s kickoff meeting—community questionnaire Complete Assessment of Community Mapping Needs (CTC Agreement) FEMA will research FIS/FIRM and other data for each community With FEMA, evaluate post-Hurricane Floyd data Step 1 – Initial Research and Community Coordination

22. NC Floodplain Mapping Program Your response is very important! Information you provide will assist the State in developing Statewide inventory of flood mapping needs Have questions or need help completing the questionnaire? –Call (877) 336-2627 (toll free) Community Questionnaire

23. NC Floodplain Mapping Program Please send the completed assessment form (mail, fax, or e-mail) to Ken Taylor –Submission information is contained in the questionnaire Digital version of questionnaire available (in MS Excel format) –E-mail request to map.specialist@dewberry.com Please submit by September 29, 2000 Community Questionnaire (continued)

24. NC Floodplain Mapping Program Meetings in each county Present results of Step 1 research Ask for community input Meet individually with county and each community’s representatives Each county and community will be contacted to schedule the meeting Step 2 – Initial Scoping Meetings

25. NC Floodplain Mapping Program Synthesize research and community input Draft basin plans will include: –Comprehensive lists of flooding sources to be updated –Counties for which DFIRMs will be produced –Overall schedule Step 3 – Draft Basin Plans

26. NC Floodplain Mapping Program Meetings held in each basin Two or three separate meetings may be held in larger basins All impacted counties and communities will be invited Present draft basin-wide plans Provide final opportunity for input Step 4 – Final Scoping Meeting

27. NC Floodplain Mapping Program Final basin plans will be used to: –Complete CTS Task Agreement with FEMA –Develop Delivery Orders for our mapping contractor –Develop CTC Mapping Activity Agreements with any counties or local communities –Production phase will then begin Step 5 – Final Basin Plans
