My question was ruled out of order, presumably due to CP 50-21, which forbids us from talking about pricing. Well how are we supposed to talk about the cost impact of a proposal to allow a product manufactured by a single manufacturer without talking about that price? www.iccsafe.org/wp-content/u...

The National Zoning Atlas team is out with a blockbuster paper identifying major flaws with the Wharton Index, which has historically been the tool used by economists to make claims about zoning (e.g. Glaeser & Gyourko's 2002 paper on zoning & affordability, with >1200 citations, is based on it...)

Karen Bass reelection update: the mayor has come out as anti-taco stand. In Los Angeles.
“I do not believe that you should have a food vendor in front of a restaurant, period,” Bass shot back, adding that she wanted them off the streets completely and in brick-and-mortar locations. Their presence near restaurants “discourages people from going in, just like you shouldn’t have encampments in front of restaurants or in front of schools. You just should not do that.”

This is REALLY important. The main thing that makes it hard to achieve integrated nature/green in cities ISN’T the density of buildings or the density of people — it's the density of CARS. And the better designed your density of people and buildings is, the fewer cars you need or want. #UrbanTruth

The median single-family detached house in Los Angeles is over $940,000. The median condo? $650,000. That’s nearly $300,000 less, so why aren’t we building them? Builders have walked away because a broken process made condos too risky to be worth it. AB 1903 (Wicks) is the fix.

An illustration showing the impact of parking requirements on land use. From left to right, the image depicts a gradient of increasing parking mandates: 'No Parking Required' allows for dense, walkable development; '1 Space per 500 Square Feet' introduces some parking; '1 Space per 250 Square Feet' adds more parking lots; and '1 Space per 100 Square Feet' results in sprawling, car-centric infrastructure with large parking lots dominating the landscape.

If you’re pushing housing in lowrise n’hoods, eliminating useless sideyards is the unlock for the urban design everybody says they want. In exchange for sideyards that no one uses, you get better units, lush interior courtyards, space for trees and play, higher density and lower energy use.
