Floodplain Mapping

Douglas County has developed an interactive mapping system that allows users to access preliminary floodplain information online and locate their property to see if their is floodplain on the property and if there was a change since it was last delineated.

Converting floodplain maps to a digital format is one more step towards FEMA’s goal to acquire better more accurate mapping. It does not address all the flaws in existing maps. However, it will make the maps easier to change in the future and reduce the costs of printing new maps in the long term. Processing Douglas County's floodplain maps to a digital format for distribution in electronic media and made available on the internet will increase availability to more people than ever before.

To use the GIS map viewer, you will need to access the website, Douglas County's floodplain maps  .  Follow the user's guide and it will instruct you on how to use the GIS mapping system.
