[https://twitter.com/allafarce '''Dave Guarino'''‏&nbsp;@'''allafarce''']<br/> Has anyone already done a property-level view of Prop 13 assessed/market values? Seems like data is there.

Kim-Mai Cutler‏ &nbsp;@kimmaicutler<br/> Replying to @tbuck0 @allafarce @markasaurus<br/> A regionwide map of the valuation differentials between assessments & market value would be fascinating.

note from a project member:&nbsp;
== June 16-18 'Houseathon' with SFYIMBY ==
<blockquote>"In general it would be ideal to have a name and general messaging that uses very simple, persuasive language to make it accessible to people who don't geek out on policy. In my mind, a big part of what makes this data so powerful is that once you surface it, you can trigger a strong, emotional response since it's immediately obvious to regular people how important and unfair it is, particularly because they can connect it to their own neighborhood and people they know. For example&nbsp;"Prop. 13 subsidies"&nbsp;- for almost everyone, the word "subsidy" triggers a basic sense of unfairness, particularly when it's not paired by something obviously important, like "subsidies to help poor people get health care" or whatnot."</blockquote>

Property Gains and Tax Subsidies Map
At the June 16-18 hackathon being organized by SFYIMBY /&nbsp;YIMBY Action, we plan to pitch this project and try to form at team during weekend to further the project.

*'''San Francisco Indicator Project Geographic Boundaries Interactive Map''' - This allows overlays of various divisions (Toggle Layers in Top Nav). Speaks to our question of what areas to define within the City. Possible divisions: Analysis Neighborhoods, Planning Neighborhoods, Supervisor Districts, 2010 Census Tracts, Zip Codes, Census Tracts 2000, CTA TAZ Districts, Voting Precincts, Police Department Districts, School Attendance Areas...NOTE: Planning Districts for the most part respect the Census 2010 tract boundaries.

If state law says it can’t be a formal property tax, we could just send folks an invoice, and assume their progressive Berkeley values will compel them to do the right thing. Some back-of-the-envelope math indicates that well-off, long-time homeowners sharing a quarter of their subsidies could raise over $15 million annually for affordable housing – five times more than Measure U1. We can leverage that with county, state and federal dollars many times over to fuel a massive affordable housing renaissance in Berkeley, and demonstrate a model that could generate billions statewide."''<br/> &nbsp;
