2020 Census and Redistricting Thread: California

[Starry Eyed Jagaloon]

Going back a few posts, if you have to draw OC without an OC-SD split, I'd go for something like this. It destroys the Asian opportunity district (which is nice to have but not a requirement) and splits part of Fullerton around to Irvine, but at least it doesn't have districts connecting two disparate built-up areas (for example, Oceanside and San Clemente or Yorba Lina and Corona). For the record, the South OC district is Trump+1 (so likely D) and the Irvine-Yorba Linda district is Clinton+3 (so safe D).



Edit: I could bring Huntington and Newport into the South OC seat, move Mission Viejo and Ladera Ranch into the Irvine seat, and push Yorba Linda into the Fullerton seat to restore the Asian Belt district, but I'm unconvinced Coastal OC is a stronger COI than South OC. I think in many ways, Lake Forest, Rancho Santa Margarita, Mission Viejo, San Clemente, San Juan Capistrano, Aliso Viejo, Laguna Niguel, and Newport Beach belong together more strongly than San Clemente and Huntington Beach. It is easy to view Irvine as a sort of barrier separating South OC from the rest of the county. Thoughts?

Yup, I reconfigured it. At the risk of sounding like ERM64man, which of these mostly similar ways of configuring coastal Orange County is better? The Asian Belt seat is only 35% Asian (against 40% white) but at least it exists in this version. Partisanship is essentially unchanged.

The second map is far superior from a COI perspective.

[Starry Eyed Jagaloon]

Well, I'm sold on the new OC configuration so I changed my whole Southern CA map around. Most districts remain the same, but some need to be shifted. I think it improves some of the lines in San Diego and Riverside quite a bit, and I only have one SD cut.

Updated. I paired Temecula with San Diego County while staying out of the San Diego suburbs. My new CA-48 respects San Diego suburb city lines. the CoI for CA-48 is rural areas. It largely stays out of the OC-SD suburbs.

Seems decent, but in the Sac area, it appears you put Antelope and Citrus Heights with the urban district, but an inner ring suburb would be a better pairing.  Also, is the Corona district basically a continuation of the current?

Corona is basically unchanged. West Sacramento and Citrus Heights are both inner ring suburbs. It’s fine to place them with city proper. My map is 45D-7R.

Took the advice of Blairite and Oryx. I'm not happy with district 18 at all, but I think it's a little better than the one on Blairite's map. I'm also a little bothered by some of the groupings for CA-14... I'm open to making some more changes as needed.

CA-12 is plurality Asian, as is CA-17. CA-14 is majority Asian, and CA-15 is plurality Hispanic, but plurality Asian by CVAP (fairly evenly distributed between White, Asian, and Hispanic).

I can probably ditch the majority Asian district to clean up the map from a COI standpoint. I don't think any districts here are VRA protected per Gingles, as there is no demonstrated bloc voting in the bay. Asian isn't even a good grouping, as East Asians and South Asians arent a unified group at all.

First off - I am happy that someone got the Monterray cut to work. every way so far presented ended up in a way that didn't work when factoring in other COIs. SLO is with the Salinas Valley seat, yes?

Second - is it possible for you to do a clockwise rotation in Conta Costa? I can't do the pop math from here.Put Richmond which has some AAs with Berkeley to assist AA Access, send the Vallejo seat west towards Pittsburgh-Bay Point and make it a delta seat, and them make the Tri-Valley seat clean up the Morana cut and maybe east from the Castro Valley area if more pop is needed.

Which pairing of Temecula is better, OC south hills-Temecula Fallbrook, or Hemet-Temecula-Fallbrook? Hemet-Temecula-Fallbrook requires a Corona-OC south hills split, while OC south hills-Temecula-Fallbrook requires a three-way split for one seat and Riverside-only for the other.

Don't do OC-Riverside.

I have to do either OC-Corona or OC-Fallbrook-Temecula because I put Irvine in Rouda's district. Is OC-Fallbrook-Temecula still better than OC-Corona?

Hey look, it's my old lines for SD!

I say old because I'll be posting my new SoCal stuff tomorrow.

[SevenEleven]

Should I re-do the Santa Clara districts even if it means losing an Asian-majority seat?

[Greedo punched first]

Since CA-47 has two incumbents, might Rouda take CA-44 because he already represents Huntington Beach and Garden Grove?

OC-Corona is less horrible, but you should change what you did with Irvine instead. It isn't worth it.

You should split it so you don't have to do OC-Riverside County. That's the one Southern California county pairing that's really never justified.

[Starry Eyed Jagaloon]

Probably. If you can get both CA-14 and CA-15 above 40% Asian CVAP, that would be ideal. Usually, I'd suggest pushing into Fremont and Union City with one of the Asian districts but that would mess up your Monterey/Santa Cruz configuration which you seem quite set on.

Yeah, I can get them both easily above 40% and it looks a lot cleaner. CA-12, CA-14, CA-15, and CA-17 are all Asian plurality.

Yep. Connecting two spread out areas via Camp Pendleton is pretty awkward, and if you start to take in some of Oceanside you won't have much of South OC left to work with. Again, there are alternatives to OC-Riverside. When splitting OC, these are the cuts from best to worst:

1. La Habra/Fullerton/Buena Park/Cypress to SE LA County.
2. San Clemente/San Juan Capistrano to Oceanside
3. Seal Beach/Huntington Beach to Long Beach
4. Fullerton/Brea/Yorba Linda to Puente Hills/Walnut
5. Yorba Linda/Anaheim Hills to Corona

[Starry Eyed Jagaloon]

In general, I much prefer the second to the first but that Lassen-Gold Country seat hurts.

I'm not taking in Oceanside. Is the combination of OC-Corona and Temecula-Fallbrook not nearly as bad as a Riverside-only seat and OC-Temecula-Fallbrook combination?

Going from OC-SD-Temecula is terrible, Oceanside or not. OC-Corona is better, but still a bad choice.
