To distill this down to a memorable heuristic, the cost of building out a municipal network of any kind is proportional to the mean linear distance of the street frontage.
This has interesting implications for civic planning. It is very much cheaper to put dwellings right on the frontage line, with zero-setbacks to adjacent properties, and then have huge backyards, than it is to center each building on its lot. That relatively small distance between the street/conduit/pole/pipe and one building is multiplied thousands of times across a municipality. An extra meter of frontage on a property at the root-end of a street is counted multiple times when calculating distances to properties closer to the leaf-end of the street.
Things that seem relatively minor for individual properties, like residential street widths, setbacks, minimum lot sizes, and maximum building heights, these have a huge impact on the cost of building municipal service networks. Those zoning rules established for aesthetic reasons literally create millions of dollars of economic impact. You just can't have cheap fiber to the premises if your premises can't be closer than 20' to the property line.
