Our neighborhood is zoned for horses. However my neighbors don't like horses, the smell and the occasional presence of flies. We clean the corral at least twice a day, usually more often, bagging the manure. We treat urine spots on the ground with deodorizer with the same frequency. We use fly traps and fly predators. City zoning officials say we are within our rights and we maintain our horses and their corral in an exemplary manner. Is there anything we can do to forestall or pre-empt such a suit?
