Check out @GovKathyHochul's Executive Order 61 at governor.ny.gov/executive-or…, and stay tuned for our release next week of RegLab's compilation of reporting requirements across all 50 states!

1/ About 19% of patients were missing race info in their EHRs, which is self-evident. But with the novel data linkage we were able to "recover" the missing race and find substantial disparities in missingness across groups: 18% for White vs. 35% & 39% for Asian & NHPI patients.

This is a big Abundance-style problem. Desk officers spend 1+ hour per day just removing irrelevant tips, and 2 more rerouting misclassified ones. Inefficiency delays responses to actual environmental crimes (like silive.com/westshore/2018/06…) and prolongs civil enforcement actions.

Here's an example from the paper: according to federal data on life expectancy, you may conclude that Asian Americans outlive White Americans by eight years. But disaggregate the same data, and you'd find that Chinese Americans outlive Vietnamese Americans by 9.3 to 11.6 years.

These unpermitted detached accessory dwelling units were more likely to be built in less wealthy, higher density, and minority communities. We also found that almost a fifth of these were built on lots smaller than 5,445sf. Prior to July 2018, ADUs were illegal on these lots.

Here's the audio. I totally thought I was going to be able to explain this was a @sfchronicle project, but never got the chance to... audacy.com/podcast/kcbs-radi…

East Palo Alto homeowners eligible for the CalHome loan could potentially build an Aduo with a $100k construction loan, move into the Aduo, rent out the main house, pay off the loan, move back into the main home, and then rent out the Aduo at market rents epacando.org/cando-adu/

I think the key insight here is that Peacelets are an experiment in peacekeeping, in a particular hyperlocal place, with all the right stakeholders at the table. If we can't figure out peacekeeping at this scale, we can't figure it out period. (2/7)

Here's a variation on the data viz from the article. Here I plotted 32,000 dots representing all city positions, and the 4000 red dots are vacancies. I did this using ggplot2 in R. (2/4)

I also think the idea of "solidarity rents" is big. Foster a community where higher-income renters know and are proud of paying a bit more so that lower-income renters can pay a bit less. Better, I think, than inclusionary housing as-is. (2/5)

The origin of this idea was @StanfordLaw doing a similar program over the summer to encourage staff to eat at the Law School cafe. We got about $100 on our ID cards, use it or lose it. (2/6)

Here's a simplified diagram of the Big Wiggle, along with its namesake henceforth-to-be-called the Lil' Wiggle, and Market Street. One of ten #SFNext proposals out today. (2/6)

I was happy to help out with some quick data wrangling to visualize the publicly owned parcels that could be good candidate sites. Check out the exact tool we used: citysystems.github.io/sf_pub… (2/6)

I was invited to participate based on the recommendation of the fantastic @LauraWenus, who had previously invited me to talk about my research and nonprofit work on the Fixing Our City podcast in Februrary sfchronicle.com/podcasts/art… (2/6)
