Hi James. I'm really excited to be heading there next month. I was part of a team that worked periodically for a year to put those maps together. We pulled data from every city department -- their expenses and their revenue streams -- and then assembled that data ourselves. We created dozens of different maps, ultimately culminating in the mashup profit and loss map I think you're referring to.
When I say "we" I mean Urban 3 -- Joe Minicozzi's firm our of Asheville -- with me tagging along as a technical expert and, to help them think through how to do this. I didn't make any maps myself, but helped them work with the data so they could do that accurately. The original idea was that this would be a tool the city could then use and maintain, something that would inform them of their direction as they adjust policy. That part didn't happen, largely due to political changes/pushback and staff turnover.
So I don't think the city has any of this data available, and it's now a few years old (too old for current analysis, but still valuable for story telling).
Sorry I don't have an easier answer for you.
