Statewide Mapping Summary

Since 1989, there have been 14 federally declared disasters in the State of North Carolina. North Carolina's vulnerability to hurricanes and devastating flooding makes it crucial that communities and property owners have accurate, up-to-date information about flooding risks. North Carolina, through the Federal Emergency Management Agency's (FEMA) Cooperating Technical Partner initiative, has been designated as the first Cooperating Technical State (CTS). As a CTS, the State will assume primary ownership and responsibility of the National Flood Insurance Program Flood Insurance Rate Maps (FIRMs) for all North Carolina communities.
Why is North Carolina Undertaking the Flood Mapping Program?

  • Hurricane Floyd revealed flood hazard data and map limitations;
  • Approximately 55% of North Carolina Flood Maps are at least 10 years old, and 75% are at least 5 years old;
  • Federal flood mapping budgets are finite; on average, the State only receives an updated flood study for one county per year; and
  • Most counties have indicated that they do not have the resources to take on this responsibility.
  • Flood Mapping Program Funding

    The total estimated cost for the Statewide Floodplain Mapping Program is $60 million. Phase I of the project, which will include development of updated topographic and flood hazard data and production of updated FIRMs for the six eastern river basins that cover roughly half of the State (see reverse), is expected to be a $36 million effort. To date, the State has allocated $25 million for Phase I, and FEMA has contributed an additional $4.25 million.
    Program Benefits

  • Updated flood hazard data will provide current, accurate information for communities, property owners, and Federal Agencies to make proper siting and design decisions;
  • High-resolution, accurate digital elevation data will be useful for many engineering and planning applications, such as stormwater management modeling;
  • The use of updated data will dramatically reduce long-term flood losses to governmental agencies, local communities, and citizens;
  • New flood information will alert those at risk of flooding of the need to purchase flood insurance;
  • A digital Information System will allow online access to all map users 24 hours a day; and
  • Up-to-date digital maps will allow users to make efficient and accurate flood risk determinations.
  • Coordination with Other Federal Agencies

    On September 15, 2000, twenty-two Federal and local community entities joined North Carolina and FEMA in an agreement to work together to maintain accurate, up-to-date flood hazard data for the State of North Carolina. As part of this agreement, each of the parties agreed to provide input into the development of technical agreements, and where possible commit the appropriate human, technical, financial and information resources. Some of the resources that the State and FEMA need from other Federal agencies include:
    • Funding
    • Digital elevation data
    • Cross-section data for stream channels, bridges, culverts, and coastal transects suitable for engineering modeling
    • Base map data (digital orthophoto quadrangles)
    • Data about flood control structures, such as levees, dikes, and dams
    • Hydrographic and streamflow data
    • Flood hazard data, such as from ongoing or recently completed hazard studies
    • Technical guidance on implementation of advanced technologies, such as remote sensing and flood forecasting
    • Advice on designing and implementing a state-of-the-art, on-line Information Management System
    • Assistance in establishing technical and data standards
