1. The rFHL/NFHL: What’s In It For Me (WIIFM)

2. 2 What is the NFHL?  National Flood Hazard Layer  FEMA’s most up-to-date flood hazard information  Database Repository Digital Flood Insurance Rate Map (FIRM) Feature Classes and Tables submitted as part of the FIRM database Letters of Map Revision (LOMR) Physical Map Revisions (PMR)  Each FIRM Database coded with DFIRM_ID

3. 3 What is the rFHL?  Regional Flood Hazard Layer  Production & Technical Service (PTS) Contractor Responsibility BakerAECOM Risk Assessment, Mapping and Planning Partners (RAMPP) Strategic Alliance for Risk Reduction (STARR)  Database Repository FIRM Databases LOMRs PMRs  Each Database Coded with DFIRM_ID  rFHL provided to CDS and published as NFHL

4. 4 FEMA’s Digital Vision  An initiative to reduce reliance on paper maps in favor of digital mapping data.  FEMA Policy on Use of Digital Flood Hazard Data  Enable significant advantages in capability, precision, and cost for users able to use digital geospatial products;  Reduce costs associated with paper map production, handling and storage;  Encourage the use of quality local data to make administration of the NFIP more efficient and effective  Enable stakeholders who have adopted digital technology to use it for NFIP purposes.  Distribution of FIRM and LOMR data via the NFHL lowers distribution costs and reduces the need for static map images through FEMA’s MSC.

5. 5 How is the NFHL different than the FIRM Database  FIRM database on the MSC is Static  NFHL is Updated Regularly with Letters of Map Revision & PMRs  Removal of overlapping multi- county community data in special cases

6. 6 PTS Responsibility  BakerAECOM – Regions IV, VIII, & IX  RAMPP – Regions II, III, & VI  STARR – Regions I, V, VII, & X  Obtain FIRM/PMR database – Process data to NFHL schema  Incorporate LOMRs  Perform Quality Review prior to submission Topology, Duplicates, Attributes

7. 7 Example LOMR Incorporation

8. 8 NFHL Data Usage NFHL Project Initiation Preliminary Post Preliminary EffectiveRisk MAP

9. 9 NFHL Data Usage  Project Initiation Use effective data from NFHL to initiate PMR, LOMR, or Watershed Study Use effective data to verify mapping of multi-county communities  Preliminary & Post-Preliminary Edge Match across FIRM boundaries Approximate LOMA Locations Incorporate LOMRs (digital FIRMs) Status of surrounding communities  Effective Digital Availability for Analysis Regulation/Mitigation  Risk MAP Changes since last FIRM (digital FIRM)

10. 10 Submittal & Publication Metrics  FIRM / PMR – Published on Effective Date  LOMRs Effective on Issue (EOI) – within 15 days of effective date Effective After Issue (EAI) – 5 days prior to effective date  FIRM Databases in NFHL - 1646

11. 11 Benefits  One Central Repository  Updated Flood Hazard Information within days of revision effective date  Able to understand Risk “seamlessly” – Risks Don’t STOP at Community Boundaries.  Mapping Partners Can Utilize as Base for updating Countywide Studies, Physical Map Revisions or Edge-matching  Communities and Administrators can access data for determinations/regulation/mitigation  Use with other data for additional analysis and planning  Better Understanding of Risk

13. 13 So… How do we get it?

14. 14 So… How do we get it?  NFHL GIS datasets (Statewide DVD) - integrate data with local GIS layers to perform queries and analysis www.msc.fema.gov  Map Viewer – view NFHL data on Mapping Information Platform (MIP) web page https://hazards.fema.gov/wps/portal/mapviewer  Web Map Service (WMS) – view NFHL data in mapping application such as ArcGIS Desktop and compare to other GIS layers http://hazards.fema.gov/wmsconnector/wmsconnector/Servlet/NFHL?VERSI ON=1.1.1&EST=GetFeatureInfo& http://hazards.fema.gov/wmsconnector/wmsconnector/Servlet/NFHL?VERSI ON=1.1.1&EST=GetFeatureInfo&  Google Earth – view NFHL on Google Earth images https://hazards.fema.gov/femaportal/wps/portal/NFHLWMSkmzdownload
