 Yeah, I think you're going to be planting some large evergreens and putting water to them, and I think you're done. It doesn't sound like you're going to get anything else. The HOA is not going to have the power to make them take it out after they approve them putting it in. The city might find them or the county by the day until they remove the whole thing if they did it without a permit. If they did it with a permit, it's their land, and it's unsightly, but it's perfectly legal.
