Overview of Map Modernization Process

    Prior to Map Modernization, many communities throughout Ohio had flood maps that were 10-30 years old, and many of these maps did not reflect the current flooding conditions of their particular areas. Such outdated maps directly affected flood risk management, potentially putting more citizens at risk of sustaining losses of property or lives.

    FEMA’s Flood Map Modernization initiative was a nationwide, $1 billion effort to modernize the nation’s inventory of flood maps. During this update the maps were produced in a seamless, countywide format. The digital flood layer that was generated is compatible with most Geographic Information Systems (GIS) and Auto-CAD platforms. Thus, local communities can utilize this digital data in conjunction with other data (such as parcel data) in order to enhance their local floodplain management programs.

    Such an extensive project required the collaboration of many players, including federal, regional, state, and local stakeholders. Each participated at a different level, through tasks such as data development, map production, and/or map maintenance. Without these partnerships, such a large project would not have been completed as effectively and efficiently.
