Fairly simple, I think all of the static properties, billboards, vending machines, chest tables, phone booths should be purchasable by players and they should be extortatable, used for control and managed as passive income investment properties. I have mapped the city to give an outline of what that would look like based upon the city streets and arbitrarily assigned numbers to the specific city locations, I'm willing to do work such as to take pictures of each location to create a purchasing catalog. If there is any interest in pursuing this further.
Attached is a map of the city with North being on North Road and everything I could think to map

Further I suggest the following:
Phone Booth = Used to connect to eachother for calls, preset numbers for the phonebooths and number dialable.
Mail = Mail system, send clothing items in the mail. Supporting custom clothing and makes sense to compliment bank transfers for purchases.
Newspaper = Recent PK Messages/ Setable by staff.
