We have a no discharge ordinance in my town. They do allow hunting though and my dad shoots every groundhog that’s stupid enough to walk on to his lawn. He has 5 acres and there’s 22 more behind him that the town owns. I’ve never heard of homeowners getting into trouble but it’s there when the town needs it like if some city yahoo decides to trespass during hunting season or someone decides to get some practice in some wooded area.
