The core of this post is the linked article
The Pseudoscience of Parking Requirements. The core of
that article is three bullet points:
• Remove off-street parking requirements. Developers and businesses can then
decide how many parking spaces to provide for their customers.
• Charge the right prices for on-street parking. The right prices are the lowest
prices that will leave one or two open spaces on each block, so there will be no
parking shortages. Prices will balance the demand and supply for on-street space.
• Spend the parking revenue to improve public services on the metered streets. If everybody sees their meter money at work, the new public services can make demand-based prices for on-street parking politically popular.
Given the mix-use urban buildings I've encountered recently, hotels from floor 1-5, offices from floor 6-10, condos up to the top (or something like that), street level shops, office space, I don't see how removing off-street parking requirements would address anything. If you have office workers you must allocate off-site parking space. You're still building for cars, cost of parking is subsidized by the employer or the business. The Tysons development in Northern Virginia is an example of this hell, it's attached to a giant mall and also near a metro (so there's commuter parking involved). I suppose the people who can afford this enclave will not need cars but most everyone else who visits must have one. Every time I go there I think I'm in a dystopian future where the swells live and work in shiny high towers and take futuristic transport to "the country" to take in the air and their children can pet goats. It's not a space for built for humans, at all, but I bet the architectural model looked great.
Point (2), you have to make charging for parking frictionless. There's another development in Northern Virginia called Reston Town Center, they switched from free parking to paid with an app and that caused in an unexpected furor that hasn't died down yet, I think renters are still suing the developers over that. People may be willing to pay cash but making them pay with an app, and a crappy app at that, took them over the edge. Still don't know why you just can't pay with a swipe. Also, payment systems are vulnerable to theft. People who had a choice of driving there or not, decided to not. It's mixed with condos so the people who live there, shop there, but then you've only made an enclave, have you solved anything?
