If a County Ordinance doesn’t permit the activity, the activity is disallowed. No shooting allowed under Ordinance 400, so “no shooting as a matter of right” Simply stated, “you are not allowed to shoot cans on your property.”
Amazing the way they think.
It is not really a County ordinance, but part of the zoning code, probably copied word for word from a “model zoning code” put out by a central “planner” organization. On the first page of such a “model code”, you will often find some equivalent of “Anything that is not allowed in the code is a violation of the code.”
It is an insane way to write law, but it is what it is.
