I would prefer to get the Latino VAP to at least 55% in Juan Vargas' district. It also doesn't make sense to have La Habra in the Santa Ana district. I also don't like OC-SD splits, unless they prevent LA-OC splits. LA-OC splits are fine if they prevent OC-SD splits. Will the OC-SD split If Aguilar is CA-40, Takano is CA-45, and Cisneros is CA-42; who takes CA-41?

how is an orange-riverside district better than OC-LA or OC-SD

IMO it definitely isn't. To be fair, OC-SD isn't the greatest pairing but doing it allows for much better Orange County districts so I usually include it. However, northwest Orange County and southeast LA County absolutely blend together and should have splits concentrated there. IMO, districts which cross the hills (so OC to Riverside, San Bernardino, or LA's San Gabriel Valley) should always be avoided.

OC to SGV is actually a pretty well connected area, unlike OC to Riverside. Diamond Bar and Yorba Linda can pair just fine. And it Trump's putting Huntington with Long Beach or ceding too much to an SD county based district.

[I’m not Stu]

Huntington Beach to Long Beach doesn't make sense, unless it includes just the SD-34 neighborhoods near Seal Beach and Cypress. Neither does Santa Ana to La Habra. The proposed OC-Riverside tunnel or skyway, if built, would make an OC-Riverside district more practical. Intercounty commerce is what I was thinking.

There are plenty of road connections but hills are just such obvious divider of communities to ignore. I like my district lines to follow ridgelines and other clear borders (rivers, freeways, etc.) as much as possible. A similar example would be Studio City and Hollywood. They're very connected but the former obviously belongs with the Valley and the latter with the core of the LA Basin.

[President Punxsutawney Phil]

this is what I have with SoCal. The Santa Clarita seat ends at the LA County border; the Santa Barbara CD is exclusively contained in Santa Barbara and Ventura counties; and the rural SB seat extends north to take in Mono and Inyo.

Do you mind zooming in a bit, turning on district borders, and turning off municipal borders? It's a bit hard to read this.

My Santa Clarita-Antelope Valley district is very similar

zooming in over which specific area? I'm just going to assume LA County+western OC+western Riverside+western SB+eastern Ventura.

How should I draw the Central Valley?

The more I think about it, the less I see the "Asian belt' district happening. What's the VAP on your OC Latino district?

At 66%, it is still under 50% CVAP. The commission is going to have to start here first, anything else is going to determined by how they draw the Hispanic district.

I think grouping the communities on each side of the hills makes sense and that's what they did last time, although that map is rather problematic in many ways.

[SevenEleven]

If you have something like this, you have to either cut into Irvine and push the coastal district deep into San Diego County, or you have to cross the hills into Corona.

How should I draw the Central Valley?

Are you starting with the South San Joaquin Valley without cutting into Lancaster as the current map does?

[SevenEleven]

here is a closeup.

Where was your starting point on your map? We need to fix Orange County.

I think separating San Pedro from Long Beach in favor of Huntington Beach is a non-starter. One of the biggest mistakes on the current map was CA-47.

[I’m not Stu]

How should I draw the Central Valley?

Are you starting with the South San Joaquin Valley without cutting into Lancaster as the current map does?

Yes. Lancaster is solely in CA-25. My OC Latino district is 52% Latino CVAP. Notice Lancaster on this map. My OC northern coast district is now plurality-Asian in total population

I pulled it off. I drew a plurality-Asian district while shoring up the Latino CVAP in Correa's district. Is it better to have the majority-white neighborhood in western Hawthorne in Ted Lieu's district, which is how I have it (it has more in common with Manhattan Beach than with Inglewood)?

It's 47% Latino CVAP, far ahead of the white and Asian numbers. I think it's good enough.

I was able to draw a plurality-Asian OC seat (with Huntington Beach but without Cerritos) while drawing Correa's district to be 52% Hispanic in CVAP without La Habra.

How many SD-Riverside splits do you have: None, one, or two?

[Oryxslayer]

I'm gonna give you credit Punxsutawney, your map has done (at least) one thing right. Your alignment of districts in the Imperial Valley core revealed me the way how to finally fix up the region so that all three of the seats can be BOTH majority Hispanic and and neat for their COIs. I also now got CA35 (CA36's sucessor) to be plurality Hispanic by CVAP, so that is an added bonus. So props to that.

I mean look at this outdated arrangement. Everything should always elect Hispanic's preference, but the lines on the other hand....

This wasn't aimed at you in any capacity. However, one should be aware that not just the successor to CA35 needs to be 47%+ by Hispanic CVAP, the successors to CA41 and CA31 also must be. This is basically a necessity given Hispanic(and other minority) growth in the region, and is the most obvious change coming to the map.

EDIT: I realize you might have been talking about the present CA35, because I wasn't apparent enough. The CA35 mentioned in the first paragraph is the successor to CA36, aka the palm springs seat.

My starting point was the Imperial-E Riverside county CD, followed by San Diego.

[President Punxsutawney Phil]

Redid some districts in LA county and OC.
I sought to compensate for the destruction of the dedicated Asian Belt seat by doing advantageous boundaries for Asians in CA-42 (now without heavily Hispanic La Habra), and by adding Cerritos in, even if that means a third cross OC-LA county district.
