>> infill development of existing parking lots to create mixed use neighborhoods is in reality very cheap for cities to do No. That is a radical change in needs and services. Cars don't need sewage treatment and fresh water delivery. Parking lots don't need school systems and health care. Just saying that a parking lot can be converted to houses ignores the radically different local and external needs of human reside…
Compared to the same amount of services further spread out, infill is far cheaper, and tends to generate a lot more tax revenue compared to the infrastructure needs. Here's a sort of simplified, but real-world example that uses snow clearing: https://bendyimby.com/2021/03/24/snow-and-financial-producti... Something like sewers are more complicated, but the basic equation is that you're adding things in an area that's…
Unlike in video games, "adding" load to infrastructure can cost more than running new lines. Everything from pipes to power lines have finite capacities. If a city sewer system is at capacity, as many are, dropping some more people into the middle (replacing a parking lot with houses) will require possibly ripping up the old sewer/water/power lines to expand them. And expanding their up/downstream connections. That can impact far far more than the local connection, often costing much more than green-field development. Imaging how much cost to open up and expand a sewer under any Manhattan street. Compare that to digging a trench through a green field out on the outskirts of town.
