National Flood Hazard Layer (NFHL)
The National Flood Hazard Layer (NFHL) dataset represents the current effective flood data for Knox County. This dataset is a compilation of effective Flood Insurance Rate Map (FIRM) databases and Letters of Map Change (LOMCs). KGIS received the data in December 2013, but upon the initial review of the dataset it had large amounts of missing data. After several months of revisions by FEMA, KGIS finally received a finished dataset. Although several database table/layer changes have occurred since the last update in 2007, we have been able to display the data using the same symbology KGIS has used for the last couple of years.
