"You will pay 200% your monthly property tax for each day your grass is tall" is indeed ridiculous

Agreed. Better option would be to hire someone to cut the grass and bill the property owner for it.

That's how we do it in most cities in WI. Except the city gives you a written warning by mail. If you don't do it, they just charge you some flat fee to have a city worker do it. It's expensive, but nowhere near that ludicrous.

Or... just ignore it? It's grass, not toxic waste.

Even better, subsidize it; it's valuable habitat for all kinds of species threatened by human activity.

That makes so much sense. Which is how I know they'll never implement anything like that :(
