into your action. If you all get together to go after this situation, you could put a greater degree of pressure on the relevant legal authority.
If you've got a city of 50,000 people 5 miles from you, I'm betting that the State's Attorney or District Attorney for your county represents the County's interests in civil matters. This may make things a whole lot easier. Especially if you and the other neighbors go in together. These folks have to stand for election, typically, and tend to want happy voters. Remember, "a phone call a day keeps the nuisance neighbors at bay." (Okay, a poet I'm not.) But this really has some truth, especially when the phone call's coming from a different person each day--you, your wife, your neighbor, his wife, his neighbor, his wife, etc. etc. Get every registered voter (or potential one, anyway) in the neighborhood to call in.
You should also see an attorney (again, perhaps the neighbors will go in on it with you) for purposes of having a letter drafted for you to demand remediation. This letter could offer to assist, if you want to be neighborly for the wife's sake. You need to be able to prove that you asserted your rights, and the earlier you do so, the better.
