An elevation certificate can identify your flood zone. If you do not have one, you can see what flood zone your property is by using FEMA's National Flood Hazard Layer Viewer. Type in your address and the interactive map will produce a colored overlay to identify the flood zone. Blue is Zone AE, the 100-year flood zone, and orange is Zone X, the 500-year flood zone.
If you require further assistance, please contact the Development Services Department at 713-662-8230 or the Harris County Flood Control Office at 713-684-4000. The flood plain maps are also available through the Harris County Flood Control's website at www.hcfcd.org.
