if "ANY" is the intended meaning, then paragraph (d) allows unlimited size/density in any zone w/ a minimum density--in which case, what's the point of the 12-unit cap in (c)?

But I remain confused about whether these 5 criteria must ALL be satisfied for a project to be eligible, or whether a project is eligible if ANY one is satisfied. The latter reading is suggested by inclusion of ADUs and MFH of 6-12 units on the list (a project can't be both). But...

Aren’t the “siting standards” a vehicle for cities to impose pretty much any form-based code?

"Builder's remedy" is a little-known mechanism where, if a city isn't complying with state housing laws, builders don't have to comply with the city's zoning. Then @cselmendorf.bsky.social made a viral 2019 thread about it that sparked a California building revolution.

✨ introducing… ✨ 🌇 Transportation for the Abundant Society 🚅 "Abundance" says our problem is artificial scarcity—especially housing. But you can’t build your way out if transportation policy still treats traffic flow as sacred. Transportation is the binding constraint. ssrn.com/abstract=538...

Abstract for Transportation for the Abundant Society:

A growing chorus known as the abundance movement seeks to overcome artificial scarcity in the built environment—especially housing. Yet this movement’s signature goal of increasing housing production collides with a central driver of scarcity: development restrictions rooted in traffic concerns. Advocates often assume that building more housing will generate support for needed transportation reform. Experience suggests otherwise. In auto-dependent regions, adding housing without reconfiguring transportation tends to reinforce the logic of restriction. Unlocking abundance’s promised feedback loops requires re-grounding transportation policy in its relationship to land use.

This Article makes two contributions. First, it introduces into legal analysis a core urban-planning framework: transportation accessibility, which evaluates system performance by users’ ability to reach destinations. Though facially modest, anchoring policy in accessibility would depart sharply from a century of practice, with significant implications across state and local government law.

Second, drawing on 13 original interviews with current and former transportation officials, the Article develops a novel account of institutional barriers to reform. Far from the marble corridors and mahogany courtrooms where law is articulated, transportation policy is functionally made in the unglamorous offices of state and local government. We call this institutional crucible—shaped by agency culture and industry convention as well as hard law—“transportation policy linoleum.” It helps explain why proven, seemingly unobjectionable reforms routinely wither. The Article closes with a policy playbook designed to help accessibility break through the linoleum and deliver abundance.

CONCLUSION 64

ToC continued, plus first bit of text from article:

A central claim of the emerging “abundance agenda” is that in the physical world, more is more: more housing, more clean energy, and more infrastructure to support both. Abundance brings the American promise of plenty into policy, arguing that government should expand capacity—so that individuals can access the good life and society can advance climate goals, scientific discovery, and prosperity. In both its academic and popular expressions, the ideologically diverse movement contends that law has created artificial scarcity and that the remedy is to loosen outdated constraints and rebuild state capacity so government can build and approve major projects—housing, transportation, energy, health—more quickly and reliably.
Abundance draws on a substantial literature diagnosing law-made supply constraints in American public policy. Its core question is pragmatic: how to clear regulatory blockages to enable more building. Scholars have long identified such blockages at the intersection of land use and transportation, from highways to high-speed rail. Yet even improved megaprojects would not meet most Americans’ daily transportation needs. And the connection between transportation policy and abundance remains underdeveloped, even as political interest grows.

You've probably heard that a group of CA tech guys wants to build a brand new port city in northern CA. The project is called "California Forever" & it's apparently breaking ground this year. Lots of folks are skeptical! On Wed., I'm going to talk with Jan Sramek, the founder/CEO. Got questions?

Read literally, it would end zoning, except in cases where a city can demonstrate that a zoning ordinance actually increases land value. Presumably it would not be read literally. So who knows.

This is a great question ⤵️. The CA Leg has made existing old, small, and often-unsafe apartment buildings almost impossible to redevelop. A big mistake. There's a real need to reconsider & standardize tenant protections, while giving tenants collective agency to authorize redevelopment.
