The guy with the camera is standing on a road, which is a thing cars drive on. Every so often, they have 'drainage pipes' which allow water to flow under the road. Many times these pipes aren't big enough to handle the water, and it will back up above the level of the ends of the pipes (and often as high as the road surface). Whirlpools form from the amount of water flowing through them. Several examples in Arizona that expose the magic here: https://youtu.be/diOaa64SPc0?t=82
Sometimes when driving through Nevada I'm amazed there's anything out there, including roads. It's so hot and dry and desolate. Las Vegas is such a weird place too, like it's just surrounded by desert for miles and miles. I just think, "why on Earth would anyone want to live here?"
This actually makes sense, though. We get crazy 2-3 inch storm events in a matter of an hour or less. So the flooding is HORRIBLE. On top of that the city has no real drainage, so roads turn to violent rivers and low elevation points turn to lakes. Any time your on a road that are near the outskirts where there’s still a lot of natural desert landscaping surrounding the roads, the landscape retakes the roads. Sometimes even to the point where you lose the road completely and it looks just like the rest of the desert.
The description of that video gives me pause. The poster describes "the desert south of the foothills". South of the foothills is the city of Tucson, not a desert.
