Call Before You Dig

Request Locates with Texas811 and the City Before You Dig.

Whether you are a homeowner planting trees or an excavation company digging foundations - everyone must check for underground utility lines before digging.

Texas state law requires that you must call 811 to locate natural gas pipes, electric lines, and other underground utilities before digging to prevent damages.

In addition, if your project includes digging within any right-of-way in University Park, you must contact the City to locate any water lines, sewer lines, traffic signal conduits, or City fiber optic lines.
