When I see my neighbors' gardeners using gas-powered leaf blowers, I walk over to them (the gardeners) and inform them that gas-powered blowers are banned. They usually comply, for that day. Usually, they are back at it the following week. It happened again, this morning. They know it, but they refuse to obey the city codes. The police don't enforce it either. However, if the property owner is fined, I think it would end, almost overnight. $100 for first violation; $200 for second violation; $500 for third violation; $2000 for fourth violation, and so on. The property owners will soon realize that it is more financially attractive to pay their gardeners more to obey the law. Also, it should no longer be 'complaint based'...any patrol officer that sees it, should write a ticket to the property owner...lots of money to made by the city for a short while!
