A plat is required when land is divided for the purpose of sale or transfer of ownership, or when creating a new building site prior to issuance of a building permit inside the city limits.
A plat is also required to attain connections to a public utility, such as electricity, in an area extending 5 miles beyond the current City limits, known as extraterritorial jurisdiction (ETJ). The ETJ is identified on an official map kept on file in the City Planning Department. Platting is required unless an exception is authorized by the City's platting and subdivision ordinance or by State laws that govern platting.
