If you wind up getting in trouble over the state of your yard, including your portion of the alley, you'll wind up footing the bill for a contractor to come out and take care of it.
There are times that you see something in Amarillo. Sometimes it is something in your own back yard so to speak. You want to notify someone. The problem is you don't know who to call. You don't want to be on this endless "please hold" while they transfer you to someone else.
