Is it even worth it? What most of the users will be doing is enter the address in their map or route app of their choice to see on a map the directions. Especially for something that's inside a park an address is really not that useful, but also outside most people don't know where some specific house number is.
Also having zones might not be super useful. Like when I'm in a city next to the border of a district I wouldn't want to only search in my current district. Something on the other side of my current district might be much harder to reach than something in the neighboring district.
Giving a place nearby, like a landmark, can aid in finding interesting places, but in the end a simple radius search, or route distance search or even something next to a path, might be much more useful. Which is more or less what is being done when you visualize points on a map.
Staying closer to coordinates also gets rid of localization issues. And that's not just different languages and scripts but also how addresses are used worldwide. There are some important cultural differences.
