Its purely aesthetics. They put it in because like a third of the “city” (like 5k people) is abandoned so they want to go on to those properties to cut everything down. Which is dumb because you have to poison the invasive weeds that are here to kill them. They just pop right back up if you cut them. But I guess thats how they keep the money coming in, they charge like $400 per hour. I manage my garden, its far away from the road, I pull or poison any invasives. But I let native plants grow. Old people just see plants that aren’t perfectly manicured and call the city. And nobody has lawns here, they want the entire city to just be bare gravel.
