  1. Multi-Hazard Flood Map Modernization NOAA Height Mod Conference 12/1/06 Dave Jula, Michael Baker Jr., Inc.

  2. Introduction Accurate information about risks is the first step in preventing and reducing losses.

  3. Introduction To support the vision, “A Nation Prepared,” the Federal Emergency Management Agency (FEMA), has undertaken the Map Modernization effort to update the Nation’s flood hazard maps.

  4. Map Modernization Objectives Enabling Technology Effective Program Management Establishes Premier Data Collection and Delivery System Provides for the Efficient use of National Resources Partners Delivering Results Empowering the User Community Builds and Maintains Mutually Beneficial Partnerships Creates Better Informed Users

  5. Who Benefits from Map Modernization?

  6. Program Management OMB DHS FEMA EXECUTIVE BRANCH GAO LEGISLATIVE BRANCH FEMA

  7. Mapping Information Platform (MIP) How Does it Help? • Proactive Centralized Project Management and Tracking • Standard Data Collection Search and Storage • Free Tools Available What is the MIP? Web-Based Technology that Enables the Management, Extraction, Sharing, and Production of Map Modernization Data

  8. MIP 4 Perform task and update MIP 3 Identify Problem by Reviewing Project Summary and Reports Tracking and Management Tool for Map Mod • Over 1,290 Active Studies • Over 20,000 MT-1s (LOMAs) • Over 1,400 MT-2s (LOMRs) • Over 20,000 Communities • Over 60 Contractors • Over 200 CTPs http://hazards.fema.gov

  9. MIP: Repository The geospatial platform will be the repository for the national GIS data layer and will store the following: • Final Digital Flood Insurance Rate Map (DFIRM) data • Intermediate data, including the outputs of key steps used to create the DFIRM data. • Scoping • Survey • Elevation • Hydrology and hydraulics modeling data • Base Flood Elevations (BFEs) • Flood outlines and other pertinent data

  10. Websites and Technology

  11. Role of the NSP The MOD Team helps FEMA with all aspects of Map Modernization: • Map Production • Map Adoption • Outreach Activities • Program Management • Geospatial Platform

  12. Metrics

  13. Colorado Risk

  14. MHIP Balancing National Goals with Local Needs

  15. MHIP – Stakeholder Involvement We are here!

  16. Elevation Data Data Capture Standards NDEP/NDOP

  17. Purpose of Data Capture Standards • Provide a consistent framework for collection, storage, and retrieval of the data needed for a Flood Insurance Study (FIS) • Describe what needs to be captured from digital data that was used in the FIS • Capture key data required for model maintenance and quality control • Verify that the data can be accessed easily and used for other projects

  18. Survey Data

  19. Survey Data • Complete digital submission of all survey data files, photographs, sketches, and notes • Data specifications for surveyed cross sections and structures • Cross sections • Bridges • Culverts • Dams • Elevation Reference Marks • High water marks • Levees

  20. Acceptable Data Formats • Sketches • Adobe Acrobat (PDF) • PNG • JPG • Spatial files • ESRI shapefiles • Open GML format • Database tables • Microsoft Access 2000 • dBase IV tables • Metadata • Photographs • Portable Network Graphic (PNG) • JPEG (JPG) • Bitmap (BMP)

  21. Terrain Data

  23. Acceptable Terrain Data Formats • ArcInfo TIN generate line or point • AutoCAD DXF • ESRI grid ASCII • Comma or space delimited point text • LAS binary LIDAR points • Point shapefile • Polyline shapefile

  24. NDEP Purpose: • To track proposed, planned, in-work, and completed projects and associated details Users: • Producers and users of high-quality elevation data • Anyone interested in where and when future elevation data acquisition might happen

  25. NDEP National Digital Elevation Program http://hazards.fema.gov/metadata/NDEP/

  26. NDEP

  27. FEMA Map Assistance Center (FMAC) 1-877 FEMA MAP FMAC representatives also handle map revision inquiries from: • Surveyors • Engineers • Lenders • Insurance Agents • Appraisers • Floodplain Managers
