  21. Status Updates: DFIRM Graphic Specifications

  22. NC DFIRM Prototype • North Carolina DFIRM prototype has been developed for review: • Three colors • Customized border, legend, and title block • Customized map symbology • 10,000’ x 10,000’ grid tiling • “Statewide” mapping • One panel includes all communities/counties in that tile

  23. Status Updates: DFIRM Database Specifications

  24. NC DFIRM Database • North Carolina DFIRM database design underway: • Incorporates FEMA’s standard DFIRM database items • Base map data • DFIRM features • Enhanced features • Field inventory • H&H model input and results • Supports future map updates

  25. Status Updates: Partnering

  26. Information Technology Requirements Analysis and Preliminary Design

  27. User Requirements Analysis • User Requirements Document produced in draft form • Summarizes survey and interview results • Establishes set of functional and data requirements • Will serve as basis for system design • Review needed by CTS Committee • Location is www.ncfloodmaps.com

  28. Preliminary System Design • Preliminary System Design Document available in draft form by April 18th • Builds on content of User Requirements Document • Establishes initial design parameters • Enumerates options for future detailed consideration • Outlines potential implementation risks

  29. Next Steps for IT Component • Finalize User Requirements Document • Finalize Preliminary System Design Document • Develop schedule and work content for Detailed Design and Implementation Phase • Prepare and issue Delivery Order for next phase

  30. Base Map Data Collection/Community Partnering

  31. Working Group Reports/Updates: Higher Standards

  32. Preliminary/Post-Preliminary Processing forNC FISs and FIRMs

  33. Current FEMA Processing • Preliminary FIS and FIRM issued • 30-day comment period • Final Community Meeting • Publication of proposed flood elevation determination in Federal Register and twice in local newspaper • Community notified by letter (continued)

  34. Current FEMA Processing • 90-day appeal period initiated by second newspaper publication • Any appeal/protests resolved • Letter of Final Determination issued (establishes effective date of FIS and FIRM and begins 6-month compliance period • FIS and FIRM become effective; distributed by Map Service Center Process typically requires 1 to 1½ years

  35. 6-Month Compliance Period • To participate in the NFIP, communities must comply with Section 60.3 of the NFIP regulations • Section 60.2 requires that FEMA give communities 6 months to adopt/update ordinances that comply with Section 60.3 criteria.

  36. Land-Use Classification Type of Flood Hazard Information Shown on FIRM 100-Year Flooding BFEs Floodways V Zones 60.3(a) No No No No 60.3(b) Yes No No No 60.3(c) Yes Yes No No 60.3(d) Yes Yes Yes No 60.3(e) Yes Yes No Yes 60.3(d) & (e) Yes Yes Yes Yes Land Management and Use Criteria

  37. Compliance with60.3 Criteria • Most North Carolina communities have adopted 60.3(d)- and 60.3(e)-level model ordinances even without a floodwayand V zones • Most NC community ordinances specify that they apply as of the date of initial community NFIP map and “to any subsequent revisions” • For these communities, current ordinances will be adequate, and 6-month compliance period will not be needed • Others will have to update ordinances

  38. Post-Preliminary Processing for NC Counties in More than 1 Basin • Majority of Phase I North Carolina counties located in more thanone basin • Engineering for basins will not be completed at the same time • Engineering for portions of counties may be completed as much as a year before the other portions (longer for counties located partially in Phase II basins)

  39. Post-Preliminary Processing for NC Counties in More than 1 Basin • Method of post-Preliminary processing must: • Meet all statutory and regulatory requirements for due process • Reduce time frames as much as possible • Be cost effective

  40. Recommended Method • Issue a Preliminary when the basin is completed, but include only the portion of the county in the basin • Initiate the 90-day appeal period for the Preliminary • When the other basin(s) are complete, issue a revised Preliminary(s) that includes the rest of the county and proceed with 90-day appeal period

  41. Recommended Method • If a basin affects only a portion of a panel, the Preliminary will be issued for all panels affected by the basin • For portion of panel not affectedby basin, base map informationwill be shown but not flooding information—Note on FIRM will refer users to effective map for flood hazard information in that area

  42. Recommended Method • To Expedite Processing: • Schedule news releases to take place within 1 week of issuance of the Preliminary • With Preliminary, notify community that 90-day appeal period will begin with the second news release and that the Final Meeting will be conducted during the first month of issuance of Preliminary (continued)

  43. Recommended Method • To Expedite Processing: • Thorough outreach should reduce number of technical appeals and protests, thus making it safe to initiate the appeal period prior to the final meeting • When the basins for other parts of county are completed, use the same process (continued)

  44. Recommended Method • To Expedite Processing: • When State initiates engineering and mapping for subsequent basins, give priority to areas within the basin that will complete the county • When last Preliminary for county is issued, provide notice of the appeal period and provide the effective date of the FIS and FIRM to begin the 6-month compliance period (continued)

  45. Recommended Method • To Expedite Processing: • 6-month compliance period and last 90-day appeal period will run concurrently • Final Meeting will be conducted during first month of issuance of Preliminary FIRM • Appeals will be processed on acase-by-case basis, depending onextent of area affected (continued)

  46. Recommended Method • To Expedite Processing: • Approach for counties partially in Phase II basins will be more flexible • If time lag might be more than a year, effective information for portion in Phase II might be digitized and used to develop the initial county FIS and FIRM • When Phase II basin is complete, a revision would be processed

  47. Recommended Method • Final maps will become effective within approximately 7 months after issuance of final Preliminary for the county as compared to 1 to 1½ years with FEMA’s standard process

  48. Recommended Method • For 7 of the counties that are split between basins, Watershed Concepts is going to make complete county submissions. • For these counties, the complete countywide Preliminary FIS and FIRM can be issued and the 6-month compliance period will begin as soon as the Preliminary is issued. The90-day appeal period will begin with the second Public Notice.

  49. Preparation for Preliminary and Post-Preliminary Processing • State and FEMA will begin researching community ordinances to identify communities that will have to update their ordinances

  50. DFIRM Production:Priority Listing of Counties
