Floodplain Management

This portion of the Town’s website is to provide the residents of Flower Mound with information and resources to familiarize themselves with the subject of flooding, and to become acquainted with the Town’s policies and programs related to flooding and floodplain management.

Floods are one of the most common hazards in the United States. Flood effects can be local, impacting a neighborhood or community, or very large, affecting entire river basins and multiple states.  However, all floods are not alike. Some floods develop slowly, sometimes over a period of days. But flash floods can develop quickly, sometimes in just a few minutes and without any visible signs of rain. Flash floods often have a dangerous wall of roaring water that carries rocks, mud, and other debris and can sweep away most things in its path. Overland flooding occurs outside a defined river or stream.

It is important to be aware of flood hazards no matter where you live. Even very small streams, gullies, creeks, culverts, dry streambeds, or low-lying ground that appears harmless in dry weather can flood. All communities are at risk from this hazard.
