The concept apparently first arose in Los Angeles in the mid-1920s, after a land-speculation and overbuilding crisis. LA had established comprehensive zoning, the first in the U.S., in 1904. According to [Weiss 2002], related ideas were widely discussed in the last 1920s and early 1930s by planning officials around the U.S.
A related line of thinking, we think, has been articulated more recently by Chuck Marohn, founder of the StrongTowns movement, in his arguments for "incremental development," in which most places are allowed to evolve to a somewhat higher step of use intensity, but it is limited so that land values do not go beyond what is likely feasible or development becomes unsustainable.
1926 issue in Los Angeles
Charles Marohn / StrongTowns - incremental development
Chuck Marohn (StrongTowns founder), in conversation with Scott Beyer. [Marohn 2017]:
"What I have suggested is that we should be allowed by right to incrementally build to the next level of intensity everywhere. I think have stated that would make, in 99 percent of America, upzoning."
"as the city, if you're sitting here facing literally, in Seattle, square miles of land that's financially not viable. And that's like an overhang that you have to deal with someday. To me what needs to happen in all those neighborhoods is that they need to become more intense they need to actually grow and see investment and become more viable. And that can't happen when the land prices are stuck and distorted and it can't happen when the regulations make it stuck and distorted. So my solution has been, or my approach has been let's try to figure this out by clearing away those regulations: Allowing people to build, by right, to the next increment. Let's get that going. And my sense is that what that would do is it would – a little bit of development everywhere – would drop the underlying land values down significantly.

11. Audit Planning Documents Regularly To See If They Are Creating Housing – Be Careful Not To Over Zone
Los Angeles’ Cornfield Arroyo Seco Specific Plan “CASP”...passed over four years ago, it has not produced a single unit of new housing.
"Zoning this land with that much FAR prices the land for that much FAR. It is very hard to build a building with more than 4.0 FAR with wood, which necessitates steel construction and higher costs. With land prices in the Urban Village priced for complex buildings, understandably no one has the guts to be the first to pay the high land price and build an expensive building in an industrial wasteland."
