A plain tour of the pipes, wires, ducts and lights that run beneath and above city streets, who owns them, and why they shape every renewal project.
How cities inventory roads, pipes, bridges and buildings, judge their condition and risk, and decide which repairs come first when money is limited.
Why large structures such as bridges, tunnels and overpasses need steady upkeep, how inspection works, and how cities weigh repair against removal.
How planners test whether water, sewer, power, roads and schools can absorb new homes, what counts as capacity, and what happens when a system falls short.
Why cities try to bundle utility and road work so streets are not torn up again and again, how coordination works in practice, and where it gets difficult.
How shared heating and cooling plants serve several buildings through underground pipes, where they make sense, and the costs and risks that come with them.
How local power distribution can limit or enable new buildings, what transformers and feeders have to do with redevelopment, and why upgrades take time.
How laying empty ducts during road work can make future broadband cables cheaper to install, what the practice involves, and the limits of the approach.
The difference between combined and separate sewer systems, why rain can cause overflows in older cities, and what that means for neighborhood redevelopment.
The trade-offs behind street lighting: brightness, energy cost, glare, color, perceived safety and the night sky, and how cities decide what to install.
How aging water mains affect cost, timing and reliability of renewal projects, why pipes break, and how cities decide which ones to replace first.
How buildings and districts can recycle water for flushing, irrigation and cooling, what greywater is, and the regulatory and health hurdles involved.
