My homes backyard goes into a ravine, right now there is a 4 foot fence surrounding the backyard (see picture). I would like to replace the fence with a 3 foot fence or shorter (to better see the ravine, and kinda make a cool open yard that flows into the ravine). I couldn't find anything in my cities regulations about a MIN fence height, only a max.
Questions: (1) Do most cities have a min fence height? (2) Any down side to making such a short fence? Animals coming in? etc?
