Just added LA County. I spot checked a few places I know, seems to be pretty accurate.

I added LA County data, and checked it against where I group up and where my mother and father grew up. Seems reasonably accurate so far.

Yep, that was my misconfiguration of the CloudFlare cache. Hopefully fixed now.

My mom (who is 97) has a vivid memory of seeing FDR in 1935 -- the whole extended family took the the Red Car from Compton to downtown to see his motorcade. She remembered the electric trams worked really well, especially for folks without much money.

> worked really well, especially for folks without much money

That's probably part of the reason they got rid of them. You still see that argument used against transit: "it will bring _____ to our part of town".

The main reason as far as I'm aware was due to intense lobbying from car companies. It makes absolute sense from the perspective of Ford, etc. to have alternative modes of transport be removed from the streets

It can be both. Highways didn’t get built for poor folks, but did get built right through many of their neighborhoods.

Thank you! Great link!

And here is one that is just fun to watch because of Huell Howser --

I think the best intro to LA is Cadillac Desert by Marc Reisner (it's really about the entire West and its relationship to water, but I think the first few chapters explain LA better than many other books.)

Yes, great point. What was torn down, burned, destroyed, etc. along the way isn't here. This is the surviving city, not the city as it was.

Exactly this -- This is more like the construction date of buildings that have survived. Everything demolished, burned, or replaced is invisible.

Probably should put that front and center.

The waves are partly real and partly me.

LA genuinely built in bursts. The 1920s and the postwar decade each account for over 230,000 buildings still standing, and the 1930s and 1970s onward are much thinner, so even a perfect per-year animation would surge and pause.

But really it's for performance -- I group buildings into 5-year bins and fade each bin in over its span, rather than popping each building at its exact year.

A per-year filter on a million polygons re-tessellates every visible tile, which was too slow to animate, whereas fading pre-built layers is reasonably fast.

Glad you found your house!

Did not think of that - yes that is a really interesting idea. Totally different way with interacting with data. I'm going to ponder that...
