Each municipality does it a little differently. Sometimes, there are just heights and setbacks. Sometimes there’s lot coverage. Sometimes there’s FAR. Sometimes there’s all of those and more, or only some of them.
Sam Alcorn (@samalcorn.bsky.social) reply parent
I would argue that the very existence of zoning codes ensures US cities are suboptimal for human habitation. Geographic separation of uses to encourage car dependency, apartment bans to encourage segregation, et c.
Sam Alcorn (@samalcorn.bsky.social) reply parent
One problem is different things being governed by different codes. For example, lot coverage by zoning codes. Floor area zoning (or economically building) Strict limits on heights are from zoning codes. Insistence on 2 stairs for all but short bldgs is the only strictly building code thing there.

@governor.ca.gov, sign SB 79! It applies to much less than a fifth of one percent of the area of the state, so if you hear anyone refer to it as "one size fits all" you know with certainty they're being disingenuous at best.

To say that the areas of our state around the transit stops we’ve spent billions on should be allowed to be restricted to low-density uses is utterly crazy.
Sam Alcorn (@samalcorn.bsky.social) reply parent
Even as it was originally introduced, it never applied to a large proportion of the state. Before the area that it would apply to got whittled away amendment by amendment, it was still a tiny area.
Sam Alcorn (@samalcorn.bsky.social) reply parent
Many of the exclusions will be difficult to map, for instance, the ones that require calculation of the existing zoned capacity of jurisdictions, what's already built in low-resource census tracts, et c.
Sam Alcorn (@samalcorn.bsky.social) reply parent
So to call this bill "one size fits all" is _extremely_ disingenuous.

Sam Alcorn (@samalcorn.bsky.social)
SB 79 rough area calculations w/in ½ mile of Tier 1 without exclusions beyond UTC & VHFHZ : 0.04% of state area w/in ½ mile of Tier 2 without exclusions beyond UTC & VHFHZ : 0.2% of state area These estimates are assuredly much too high, as they only exclude 2 of the many exemptions

TBF, it was already the longest light rail line on earth by a wide margin as of the completion of the Downtown Regional Connector a few years ago. This latest extension to Pomona added another 9 miles (but only a few stops).

So yes, zoning does separate low-density residential zones from industrial zones, by using higher density residential as a buffer between them.
Sam Alcorn (@samalcorn.bsky.social) reply parent
This is a common thing seen in cities all over the US: high-density residential directly adjacent to industrial zones, and then lower-density residential farther from the industrial.
Sam Alcorn (@samalcorn.bsky.social) reply parent
But Euclid had designated a strip of that property for apartments (with no road), between the industrial zone adjacent to the railroad and the duplex zone fronting Euclid Ave.
Sam Alcorn (@samalcorn.bsky.social) reply parent
Let’s take for example the zoning at the heart of the Euclid case: Ambler Realty wanted their whole site to be industrial, as neighboring properties along that railroad had been, and as this one ended up being developed after the case, for WWII.
Sam Alcorn (@samalcorn.bsky.social) reply parent
It wasn’t about that, even at first. The earliest zoning ordinances in Berkeley, Los Angeles, and NYC were all about excluding certain groups of people. The “separating industry from residential” thing was a post-hoc rationalization. Nuisance laws greatly pre-dated the emergence of zoning.

There should be a state law mandating that there be shaded and safe sidewalks associated with both sides of every road. Not just new roads or triggered by alteration of existing roads, but that would be retroactive and proactively enforced.

And as the SB 79 definition of “heavy rail” goes by line, all stops on a line where any parts of it where cars and people cross its path should count as Tier 2, even if that particular stop is in a tunnel or freeway median.

Sam Alcorn (@samalcorn.bsky.social) reply parent
I think you’re right. If a line has some places where cars or people could pass in front of it, I think it would count as “light rail” per SB 79. Like with the LA Metro A line, where board it it’s in a tunnel, but there are parts where it goes on the street, like in Highland Park.
Sam Alcorn (@samalcorn.bsky.social) reply parent
and VTA rail in Santa Clara County, which have high platform loading and are grade-separated. Obviously nothing will get published before the Gov signs the bill, but I wonder what sort of timeline we’re looking at?
Sam Alcorn (@samalcorn.bsky.social) reply parent
By the text of SB 79, the MPOs are supposed to publish authoritative lists of which stops count as Tier 1 and Tier 2. Do you know if these will be aggregated statewide? Also interesting is what counts as “heavy rail” includes some lines that I would think of as “light rail,” e.g. LA Metro Line C…
Sam Alcorn (@samalcorn.bsky.social) reply parent
Similar question about high- and very-high-frequency commuter rail, only there, the definition references the “system” rather than the “line.”
Sam Alcorn (@samalcorn.bsky.social) reply parent
I ride the A Line more than the E. But it does seem like it meets some of the definition for “heavy rail” rather than “light rail” at some, but not all stops. But since the definition talks about the line having those characteristics and not the stops, I’ve been counting it as Tier 2.
Sam Alcorn (@samalcorn.bsky.social) reply parent
And at some point, we should get authoritative maps from each MPO about which stops count as Tier 1 and Tier 2 per SB 79. In the mean time, I’ve worked up my own. The tricky part is just in LA County, where you have to sort the heavy and light rail by route, since they’re run by the same operator.

On some streets, the crown of the street is higher than the sidewalks.
Sam Alcorn (@samalcorn.bsky.social) reply parent
sidewalk height, so on big arterials, you might end up with just raised crosswalks at both sides, but not in the middle. Emergency services like fire trucks and ambulances could thus go through intersections without bumps, which will be a point of pushback from them.
Sam Alcorn (@samalcorn.bsky.social) reply parent
They will need embedded pipes or similar at the edges of each street, along the street gutter, which must be sufficiently numerous to deal with drainage during heavy rain, so they don’t back up the gutter. And on a wide enough street, the crown of the street in the center of the road can approach…

State reps in CA are listed with “party preference,” except for elected judges. Federal races are listed with the candidates’ parties in a more matter-of-fact way. I just now looked at an old ballot to confirm.
Sam Alcorn (@samalcorn.bsky.social) reply parent
So if you want to know what party a candidate is associated with for a municipal race, you’ve got to do a bit of research. It’s been like that everywhere I’ve lived in CA: LA, Santa Monica, Pasadena, et c. I think it was that way when I lived in Denver years ago, too.
Sam Alcorn (@samalcorn.bsky.social) reply parent
Some places, like here, don’t list parties of candidates for council or other municipal positions on ballots, from city up to county. Sometimes during campaigns, you’ll see advertised the endorsement of some state or local branch of the apparatus of a national party.
Sam Alcorn (@samalcorn.bsky.social) reply parent
At-large seats should result in a more representative body than single-member districts with first-past-the-post voting. And those things are what lead us to have 2 political parties in the first place. So you’d expect many more parties.

15 city councilors is way too few for a city of LA’s size. It should be at least 50, with very strict and limited campaign finance rules (like maybe <$20/donor, no self-funding, and maybe public matching), and term limits. I’m not imagining a single change here would fix the problems.
Sam Alcorn (@samalcorn.bsky.social) reply parent
City councils should be composed of at-large seats, for many reasons. Less corruption, more democracy, more housing. Enough with districts! LA already has neighborhood councils to provide hyper-local elected representation.
