Abolishing parking minimums, and, in fact, establishing parking maximums, would be a great, easy, and inexpensive step for most cities in the US. You literally can’t build dense walkable places like old main streets anymore because of zoning codes and (chiefly) parking minimums. If you’re like me, you probably assumed that these codes had their feet in good reasons for existing, but they actually don’t. Parking minimums are often based on numbers that are essentially snatched out of thin air and not evidence-based, and many other cities simply copy what other cities are doing. Aggressive exclusionary zoning often has its feet in racism, and it’s a big reason why only US cities seem to experience urban decay. This is something you can change! Go to your city council meetings, network with people there! Go to your city planning board meetings, read your city’s zoning laws, and go give them very specific shit about it! These offices are infinitely more accessible and responsive than state and federal legislators, and you might be surprised to find that some of them even agree with you! It doesn’t take much effort, it’s pretty much free, and the cops can’t stop you!
