The easiest way to play in google docs is probably just a blank page that all your players can edit, with different indentation for Neighborhoods/ Landmarks/ Residents, but if you want something with a bit more polish:

If you want to play in google sheets, Kurt Refling has made two templates that are super easy to copy over — one that you can modify manually, and one that generates formatting using an automatic script.

If you want something with more of a flowchart quality, Miro and Coggle are two mind mapping/flowchart apps that I've found work alright for online play. If you want something that’s a little more structured than a flowchart but not as linear as a google doc, I’ve heard of folks playing in Gingko and Trello. I haven't played a session in either firsthand so I can’t speak to their quality, but they seem like sensible options.

Hope this helps!
