This project will be a good litmus test for JLG’s attitude towards bike lanes: it’s short (<0.5 mi), it fills a key gap in the network, and it has strong ANC + WABA support BUT it would require removing ~64 parking spaces (by my count) in one of the densest parts of the city

new from @sp-ainsworth.bsky.social & me, a back of the ✉️ estimate in @ggwash.org: 🚌&🚲lane projects save 1-2 human lives per year, & create societal savings of $88-$111M/year, just in avoided crashes. We don't capture every project or ancillary health benefits, so this could be an underestimate.

Chart showing DDOT’s bike lanes have had gigantic safety benefits, reducing total crashes by 40% and injurious crashes by 60% on the corridors where they are installed. These 24 bike lanes have saved an estimated 1-2 human lives per year.

yellow map: areas where McDuffie did better. blue map: wealthy R-1-A and R-1-B zones that have only allowed detached housing for ~100 years

map showing places Kenyan McDuffie did better. It's very similar to the places in DC that have R-1 zoning, which bans duplexes and apartment buildings.

seems like voters in R-1-A and R-1-B zones voted disproportionately for Kenyan McDuffie. (not a perfect correlation obvi, and they're still counting votes)

a map showing DC's R-1A and R-1B zoning areas. There's a ton of overlap with the areas that Kenyan McDuffie did better in, at least in the initial results the morning after the election.

1. London Underground station flooding has reportedly been reduced by around 90% thanks to a group of engineers: beavers. After conservationists reintroduced a family of beavers into a nearby city park, the animals built dams and restored wetlands that now absorb and slow floodwater naturally.

This was also an odd window into the Caribbean cruise economy. The walkable mini town is surrounded by a fence and most of the biz are closed when a cruise ship isn't docked (tho we grabbed coffee at a nice cafe that was open all day for locals). When docked the ships belch exhaust over the town

was on vacation in the British Virgin Islands and walked to the cruise ship port in Road Town, Tortola. The cruise passengers are dropped right off into a miniature town in which cars are banned. Odd reminder that many Americans love walkable neighborhoods but think of them as a vacation thing

A sign in the miniature town next to the Tortola, BVI cruise ship stop that says "pedestrian only."

How, in 2016, we got less of Lanier Heights

While the District’s population went up by 15% between 2010 and 2020, Lanier Heights’ population increased only 3%. A downzoning is a big part of the reason the neighborhood hasn’t grown.
