Sounds more like a touristy set of rich estates at this point, I expect the laborers live in the surrounding area and drive into town just like a large city. I did some labor during HS and in the summer it was driving 20-40 miles from our small town in nowhere Texas for the jobs we did.
During the early 80's oil boom there were several small towns in Texas that kinda looked like OP's model, but once the boom went to bust they started dying and never recovered. Probably around the Austin area in the 60's a lot of places looked more idyllic (there were no stoplights between downtown Austin and I think Lampasas at that point), but it's all sprawled out and become a Metropolis at this point.
Not clear that any sufficiently attractive area would not end up being encompassed in suburbia or a high-end enclave (Westlake by Austin comes to mind).
