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.
