- Utilities
The city lists an Electric Department, a Water/Wastewater department and Utility Billing among its departments.

Where Lockhart fits
The Texas State Historical Association says the town was named for Byrd Lockhart, who received the land in 1831 as partial payment for surveying work, and that it was incorporated in 1852.
Its ZIP, 78644, is its own. A Lockhart address is a short drive from Kyle but sits in a different county, so county offices differ.

How to use the list
A water loss that opens walls or replaces plumbing can trigger a permit and an inspection. The call to make first is the permit desk, because it also covers whether the contractor you plan to use has to register with the city.
If you are unsure whether an address sits in a mapped flood area, the floodplain contact above is the one to ask. Caldwell County, not Hays County, is the county for Lockhart, so the Hays County floodplain office in Kyle does not cover it.
A sensible order of calls
The utility first
Shut off the water at the meter or main valve if the source is on your side. If the leak is on the street side, the city's Water/Wastewater department is the one to reach through the main line, 512-398-3461.
Then the permit desk
If walls, floors or plumbing will be replaced, ask the Permit Technician at 512-376-9939 what needs a permit and whether your contractor must register.
Then the floodplain contact
If water came in from outside, the Planning and GIS Coordinator at extension 2430 can speak to maps and floodplain questions.
Through all of it
Photograph, keep receipts and tell your insurer. The line connects you with an independent contractor for the water in the house.
