The Case for City-Built Broadband\n\nVery nearly every argument about internet service ends up back at a hole in the ground. Before anyone streams anything, somebody has to open a street, lay conduit, pull glass through it, and patch the street back up. That work is slow, disruptive, and expensive, and it is the main reason residential broadband competition is so thin in most towns. The first company to arrive pays for the digging; a second company would have to pay for the same digging all over again, for a market it would then have to split. Cities, though, already own the streets. They own the rights-of-way, they run the permitting process, and in a lot of places they own the poles. City governments should build and operate their own broadband networks, because the expensive and long-lived part of broadband is a public works problem, and public works is something cities already know how to do.\n\nStart with what the money actually buys. Halvorsen separates a fiber network into two layers: the passive layer, meaning conduit, ducts, poles, and the fiber strands themselves, and the active layer, meaning the active equipment in the cabinets that turn glass into a working connection. The two layers behave nothing alike. Active equipment gets replaced roughly every eight years as standards change, but passive plant, once it is in the ground and undisturbed, has a working life of forty years or more, and it accounts for close to seventy percent of what the system costs to build in the first place (Halvorsen 26). That split explains why private capital struggles here. A firm answering to investors has to earn the trench back on a schedule investors will tolerate, which pushes it toward the densest blocks and the highest margins. A city issuing thirty-year revenue bonds is matching the repayment period to the actual life of the asset. That is not generosity. It is using a financing instrument that fits the thing being financed.\n\nThe second advantage cities have is that they are already large buyers of the exact product. Mwangi's comparative work on mid-sized public utilities makes this clearer than anything else I read. Before Amberton built its network, the city was leasing circuits from outside vendors to connect nine school buildings, four fire stations, the storm drainage plant, the library branches, and the traffic signal system, and it had long since stopped questioning the annual bill (Mwangi 303). When the municipal fiber came online those leases ended and the money went to debt service instead. In Amberton's first full year, the city's own internal use covered a little under a third of what it owed on the bonds (Mwangi 305). No private entrant has a floor like that. A competitor earns nothing until households start signing up, while a city begins the year with a guaranteed anchor tenant that happens to be itself.\n\nBut can a city government, an institution that in many places cannot repave a road on schedule or answer the phone at the permit desk, really be trusted to run a technology utility?\n\nA further advantage of public ownership is that the price is set in the open. A municipal rate schedule is adopted at a council meeting, printed in the agenda packet, and posted afterward, which means the number a subscriber pays was arrived at in a room anyone could have sat in. Halvorsen compared advertised rates against actual first-year billed amounts for both public and private providers and found the gap between the two was substantially narrower for municipal systems, largely because public networks rarely use promotional rates that expire, and because equipment charges have to appear in the adopted schedule rather than surface later (Halvorsen 31). Whatever else can be said about a city utility, a subscriber can go read the ordinance that sets the bill.\n\nCoverage is the other place public ownership changes the outcome. Private build decisions run on density. A route gets built when the homes per mile clear a threshold, and the households past that threshold wait indefinitely. When Selby Falls chartered its network, the enabling ordinance required service to every address inside the city limits within four years with no density condition attached, and Mwangi notes that the final eight percent of addresses consumed almost a quarter of the construction budget (Mwangi 307). A private firm would never have built that last stretch, and it would not have been irrational to skip it. The difference is that a city is not choosing among customers. It is serving residents, and the residents at the edge of town pay the same taxes as the ones downtown.\n\nThe strongest objection to all of this is that fiber is a poor thing for taxpayers to own because it will be obsolete long before the bonds are retired. Wireless keeps improving, the argument goes, and the city ends up maintaining a technology nobody wants anymore. I think this misreads what a city is actually buying. Wireless service does not float free of the ground. Every tower and small cell has to hand its traffic off to something, and that something is fiber. More to the point, the asset with the forty-year life is the conduit, not what is inside it, and conduit does not care which generation of glass or electronics gets pulled through it later (Halvorsen 28). A city that owns duct under its own streets owns the option to upgrade cheaply for decades. The objection does land against a city that treats the network as a one-time gadget purchase and never budgets for the active layer, but that is a complaint about operating the thing properly, not about owning it.\n\nThe trench gets dug once. The only real question is whether the public that owns the street also owns what goes underneath it, and whether what gets built serves everyone the street runs past. Cities that build and run their own networks are answering both of those questions the right way.\n\nWorks Cited\n\nHalvorsen, Ingrid. \"Passive Plant and Public Capital: Rethinking the Broadband Balance Sheet.\" *Journal of Infrastructure Policy*, vol. 41, no. 1, 2025, pp. 22-35.\n\nMwangi, Thomas. \"Anchor Demand and Universal Build Obligations in Mid-Sized Municipal Utilities.\" *Review of Public Utility Studies*, vol. 18, no. 4, 2023, pp. 301-09."},"anomalies":[],"verification":{"source_event_count":228,"range_hash":"5e55e10a6ea61508929986ded3b9b26895fa1461711b1cb9f2e5552ea33935c6","how_to_verify":"karani verify --artifact <rendered.json> --log <events.jsonl> re-folds the log and compares the range hash.
