* I'm the initiator of this project. I started researching this while
I was living in San Francisco but moved to the east coast this year.
I'm very familiar with the built environment and OSM there.

* I don't work for Mapbox, but do provide services around OSM as a
job, often involving 3D visualization within San Francisco, so I have
a commercial as well as personal motivation for the project.

* The Mapbox Data team approached me this summer, offering their help.
They're the remote team responsible for the original 2014 tracing of
building footprints that we're augmenting [0], so this effort seems
like a good example of taking stewardship of their contributions and
making improvements. (They are also updating footprints.)

* Mapbox has offered use of their space for the local event, but it
will possibly happen after the US holiday season. We are in contact
with the Maptime SF and Bay Area OSM organizers through our chat
