None of those cities are saving money or even _planning_ for the inevitable repaving, pipe re-lining, etc. Worse: many of them were built up in waves so much of the city's infrastructure will "come due" around the same time.
I never imagined we would see San Francisco (of all places) overhaul its permit process. I can now build a deck in my backyard, add a story to my house, or build an ADU without having to pay DBI to send certified letters to all my neighbors asking if they'd like to object, then being forced in front of the planning commission when they do so. That's a direct result of the pro-housing legislation at the state level, something Wiener has been heavily involved in.
edit: nevermind, found lots of example here! https://www.google.com/maps/d/u/0/viewer?mid=1iV3NEJqsY0y8N1...
sadly lots of the big cities I was interested not included. Guessing with these it's more difficult to get the input numbers.
