Floodplain Information

Coppell has four major tributaries flowing through or adjacent to the City. These tributaries are Denton Creek, Grapevine Creek, Cottonwood Creek, and the Elm Fork of the Trinity River. Also, there are numerous small tributaries meandering through neighborhoods and eventually joining with the major tributaries.

How Flooding Occurs

Flooding can occur when the runoff caused by precipitation is too great to be confined in normal water channels. Rising water can destroy any structure or object in the floodplain.

Floodplain Permits

Before any development or improvements will be allowed in a floodplain, a floodplain development permit must be obtained from the Engineering Department. As part of the floodplain permit, additional information may be required, such as a flood study to determine if the improvements will be allowed. View the Floodplain Development Permit (PDF).
