I work at a mapping company and wanted to see where the Palisades rebuild is actually happening, lot by lot.

Green is a destroyed lot with a rebuild permit; teal is a destroyed lot with none found.

How it was counted:

• Destroyed lots: CAL FIRE's damage inspections, matched to LA County parcels (5,864 lots).
• Permits: City of LA and LA County rebuild permits, matched by parcel number, issued through August 2026.
• Demolition permits, temporary housing and applications that haven't been issued don't count.

What it can't tell you:

• Malibu's city permits aren't included, so the Malibu lots (622 of them) will read low.
• An issued permit is not a finished home.
• Some of the large teal shapes are big non-home parcels, which make the empty areas look bigger than they are.

The permits cluster in the Palisades grid; the canyons and the coast toward Malibu are mostly teal.

If you live there, does this match what you're seeing in the rebuild live?

As is well known, SF doesn't really do fall. Four of the five most common street trees in the city are evergreen, but I was curious where I could see some colors. Well, tbh my fiancée kept asking me to take her to see some fall leaves on the East coast, and I told her we have fall foliage at home lol.

I looked up the city's street tree list off DataSF (~200k trees) and kept the five species that actually turn color here (ginkgo, sweetgum, Chinese pistache, red maple, tulip tree). I loaded them into mapping tool and and counted them by street.

Top five:

1. Bryant -- 293, almost all red maple
2. Harrison -- 217, mostly Chinese pistache
3. Divisadero -- 152, red maple and ginkgo
4. Evans Ave -- 130, and it's all ginkgo.
5. 24th St -- 96, half ginkgo half maple

I thought Evans Ave was pretty surprising. It's the truck yard stretch of Bayview, and it looks like the city planted 130 ginkgos down it. Ginkgos go bright yellow and then drop everything in about a day, so that's probably the best single fall block in the city. From Google Street view though, the Ginkgos look pretty young, but if we give them a few years, I bet they'll be beautiful.

Some data caveats:

• Long streets win on raw count. Bryant and Harrison are long. I did a per-block analysis but it's less cool lol.
• These are street trees only. Parks and yards aren't included in the public dataset. Although honestly, the parks wouldn't help much. GGP, the Presidio, and Land's End were all planted in the 1880s with the same three evergreens (Monterey cypress, Monterey pine, eucalyptus).

I know the leaves won't turn until November, so I'm posting early! Just thought this was cool lol. Any other good public streets I may have missed?

Hey everyone! I saw that Chicago Strava map on X going viral last week (see first comment). People were saying running patterns mapped wealth/class across Chicago. I bike a ton in SF so I wanted to see what SF’s cycling heat map would look like!

I snapped heatmap cycling cells from Strava to actual paths then ranked all the SF neighborhoods (second pic).

I was pretty sure GGP and the Presidio would win. They were in the Top 5 but not the Top 3 lol.

Instead it was the Sunset with 51.8 miles of popular cycling routes, then Bayview at 38.1, then the Mission at 29.9. Sorta funny that the two most popular neighborhoods to bike in are on opposite ends of the city.

Ik cycling isn’t running, so the wealth / class take doesn’t map 1:1. But if you took the Chicago advice to SF, it would tell you to move to the Sunset, Bayview, or the Mission. Three great neighborhoods but def not the wealthiest in SF lol.

Anything surprise y’all abt this map?
