Flood Plain Information

All development in the unincorporated areas of McLennan County must comply with the county's flood damage prevention order.

McLennan County provides floodplain information in order to determine if a certain tract of land is within the 100-year floodplain. You will need to provide the Engineer's Office with a survey or drawing that shows the specific tract, the fronting road, and the nearest road intersection.

If you need a drawing of this nature, contact the Map Department by calling 254-757-5067.

Once a drawing has been provided, the Engineer's Office will make a determination as to whether the property lies within the floodplain.
