As it is said the goldfish can't see the water because he is in it, Austin has been unable to see beyond its own mess to realize it has been promoting, creating, and solidifying it. Austin law requires every building to reserve and create a massive amount of space for automobiles. That is on top of the massive funding required to support the roads in between these buildings. It is not surprising sidewalks have been an afterthought in a city that makes mighty claims.
In reality, Austin is no different than any other large Texas city. If anything, it ranks higher in hypocrisy with claims of being "green" and environmentally conscious. And it is the exact same law that has created difficulty for those with mobility issues for decades.
Code Chapter 25-6-471 is the law that is strictly enforced and has required housing cars for the better part of a century.
Forcing parking in housing and commercial developments forces sprawl and forces car ownership. This is a burden on the poor. The price of admission to get a job for far too many and for far too long. Not only admission but a lifetime of headaches, unplanned expenses, and monthly charges.
Parking takes valuable space from affordable housing and green zones. It further increases the cost of building construction by 30% (affordable housing?) Housing First advocates could say we already have a "housing first" policy - for 80 years: Car housing first. We have a law that guaranties shelters for cars but no law that guaranties shelter for people.
Permitting a pro-environmental and walkable shift in infrastructure will help massively by providing opportunities for small but multiple health and job centers to spring out of the dark asphalt much closer to those who need them.
We really don't need anything fancy. We have all the answers already and we should know it. The guys gaming the system sure do. That's why everything else is a nice distraction: flying taxis, fancy apps, Google's Shweeb. The best solutions are the simplest ones, when the common people get the gains. Exactly what the profiteers fear the most.
