What to do if code enforcement wont take action on unsafe property ?

We have a neighbor in our middle cl neighborhood that has been collecting junk for the past years. and it has gone to far, the stuff he keeps collecting is by far stuff that belongs in the dump ranging from old sports bleacher beat up and wrecked cars to boats that would never float because of huge holes in them. not only does it bring the neighborhood down it is also attracting rats and other rodents. also the neighbor hood cats keep killing the rodents and littering all over the neighborhood im scared one of the neighborhood kids might get ahold of one of those rats and possible get sick also these old cars are leaking oil all over the property which is getting in the soil and possibly seeping into the well water. this is a very bad hazard and the neighbors have called our local code enforcement and no action has been taken. but they drive through our neighborhood complaining if our car is park to far from the curb or if it is backwards. and just the other day the tore down the neighborhoods kids bmx jumps they worked so had on in a empty field they told us they got a complaint from the guy that owns the house. im complaining about funny how they will react to his complaint but no one else's. my question is if code enforccement wont do there job what would be my next step? all im asking is for the trash to be removed so the rodents will go away.
