In the area of Alaska where I live, our Borough (county) has similar regulations with fines. We have a Compliance Officer and he moves very quickly, on reports of junky yards, garbage and unsafe health conditions such as septic tanks and junk cars. 
First of all, no one here waits around for a yard to fill up with junk. The CO comes out photographs the violations and tickets the homeowner. If it is not corrected within ten days, they go to court and get a judgement with a court order. They can then go onto the property and removed whatever it is and dispose of it. A bill for that is added on to the fines which is then added onto the property tax bill. Eventually, if taxes are not paid in two years the property is seized and auctioned off. I may have skipped a legal step or two, but it does get taken care of. Part of it is nipping it in the "bud". Not sitting back and wat hing the pile get higher. 
Neighbors will offer to help but if turned away it goes to the CO. We pay taxes for it
