But so much change — and so fast — has also come with challenges.
Nancy Classen, who grew up in the city and works at the Sophienburg Museum and Archives, said she was willing to keep an open mind about the new arrivals — as long as they did not try to change the town’s identify. New Braunfels, a conservative bastion between progressive cities, is the largest city in Comal County, which overwhelmingly voted for Donald J. Trump in November.
“This is still a pretty conservative town,” Ms. Classen said. “They are OK as long as they don’t try to change us. This isn’t California.”
When Terri Jennings, 58, who operates a local vintage store, asks people where they are from, many lean over the counter and whisper, “California,” as if revealing a dark secret, she said with a smile. “I think they get a little bit of flak because people think that people from the West tend to be a little more liberal.”
Even Ms. Jennings, who has lived in the city for seven years but has worked here for 16, has learned to keep her liberal tendencies to herself. “I don’t want to argue about politics,” she said. “I understand why they do it.”
Caleb Harris, 36, said he moved to New Braunfels from Utah in 2013, when he foresaw that the region had potential for expansion. He bought a property at a development called the Overlook at Creekside, north of the city’s center, as soon as it broke ground. “I knew it was going to be a good area,” Mr. Harris said.
