Municipal utility districts continue to grow outside Round Rock; annexation unlikely
As a matter of necessity, the employees of the Round Rock Public Library have become experts on city residency laws.
That is because with increasing frequency the city's librarians have found themselves informing first-time visitors that they are not actually residents of the city of Round Rock but instead reside within a municipal utility district, or MUD. The discrepancy in addresses not only affects people's ability to gain a free library card, but also the property taxes they pay, the fire and police services they receive and in which elections they are allowed to participate.
"We have a lot of people ... who don't know they are purchasing a house in a MUD or understand what a municipal utility district is," Round Rock Library Director Michelle Cervantes said.
There are approximately 37,000 people living in the 13 MUDs that lie within the city of Round Rock's extraterritorial jurisdiction, or ETJ—unincorporated areas the city holds the rights to annex but is under no obligation to do so.
