Does not look like damage from an air rifle pellet.
More like slingshot. A ball bearing or steel nut loosed from up to several hundred feet away. It could have even bounced off pavement before striking. The first hole pictured has a weird up-angle look to it.
I remember reading that Houston has potential for floods, as the terrain is flat. A new development would have a series of swales to catch and divert runoff. The little devils could hide there.

Yes, I saw that as well, but not being there when the picture was taken, I was not sure how much might be camera angle.
Still, that hole appears to be well over four feet above the ground.
