Published by City of Charlotte | City of Charlotte | Catalog Last Checked: September 24, 2026 at 05:49 PM | Dataset Last Updated: September 23, 2026 at 11:52 PM
An area of the floodplain that must be kept clear of any obstruction (fill dirt, buildings, etc) as to not impede the flow of water. Development in this area is very restrictive, and usually requires a detailed engineering analysis (and local approval) prior to beginning development. The location and width of the Community Encroachment Area is established by engineering models that determine the area needed to convey the FEMA Base Flood Discharge without increasing the water surface elevation more than 0.1 foot. The Community Encroachment Area is wider the FEMA Floodway.
