The Leakage Problem

leave a comment »

Pedestrian Observations has an interesting post:

I’ve spent more than ten years talking about the cost of construction of physical infrastructure, starting with subways and then branching on to other things, most.

And yet there’s a problem of comparable size when discussing infrastructure waste, which, lacking any better term for it, I am going to call leakage. The definition of leakage is any project that is bundled into an infrastructure package that is not useful to the project under discussion and is not costed together with it. A package, in turn, is any program that considers multiple projects together, such as a stimulus bill, a regular transport investment budget, or a referendum. The motivation for the term leakage is that money deeded to megaprojects leaks to unrelated or semi-related priorities. This often occurs for political reasons but apolitical examples exist as well.

Before going over some examples, I want to clarify that the distinction between leakage and high costs is not ironclad. Sometimes, high costs come from bundled projects that are costed together with the project at hand; in the US they’re called betterments, for example the $100 million 3 km bike lane called the Somerville Community Path for the first, aborted iteration of the Green Line Extension in Boston. This blur is endemic to general improvement projects, such as rail electrification, and also to Northeast Corridor high-speed rail plans, but elsewhere, the distinction is clearer.

Finally, while normally I focus on construction costs for public transport, leakage is a big problem in the United States for highway investment, for political reasons. As I will explain below, I believe that nearly all highway investment in the US is waste thanks to leakage, even ignoring the elevated costs of urban road tunnels.

State of good repair

A month ago, I uploaded a video about the state of good repair grift in the United States. The grift is that SOGR is maintenance spending funded out of other people’s money – namely, a multiyear capital budget – and therefore the agency can spend it with little public oversight. The construction of an expansion may be overly expensive, but at the end of the day, the line opens and the public can verify that it works, even for a legendarily delayed project like Second Avenue Subway, the Berlin-Brandenburg Airport, or the soon-to-open Tel Aviv Subway. It’s a crude mechanism, since the public can’t verify safety or efficiency, but it’s impossible to fake: if nothing opens, it embarrasses all involved publicly, as is the case for California High-Speed Rail. No such mechanism exists for maintenance, and therefore, incompetent agencies have free reins to spend money with nothing to show for it. I recently gave an example of unusually high track renewal costs in Connecticut.

The connection with leakage is that capital plans include renewal and long-term repairs and not just expansion. Thus, SOGR is leakage, and when its costs go out of control, they displace funding that could be used for expansion. The NEC Commission proposal for high-speed rail on the Northeast Corridor calls for a budget of $117 billion in 2020 dollars, but there is extensive leakage to SOGR in the New York area, especially the aforementioned Connecticut plan, and thus for such a high budget the target average speed is about 140 km/h, in line with the upgraded legacy trains that high-speed lines in Europe replace.

Regionally, too, the monetary bonfire that is SOGR sucks the oxygen out of the room. The vast majority of the funds for MTA capital plans in New York is either normal replacement or SOGR, a neverending program whose backlog never shrinks despite billions of dollars in annual funding. The MTA wants to spend $50 billion in the next 5 years on capital improvements; visible expansion, such as Second Avenue Subway phase 2, moving block signaling on more lines, and wheelchair accessibility upgrades at a few stations, consists of only a few billion dollars of this package.

This is not purely an American issue. Germany’s federal plan for transport investment calls for 269.6 billion euros in project capital funding from 2016 to 2030, including a small proportion for projects planned now to be completed after 2031; as detailed on page 14, about half of the funds for both road and rail are to go to maintenance and renewal and only 40% to expansion. But 40% for expansion is still substantially less leakage than seen in American plans like that for New York.

Betterments and other irrelevant projects

Betterments straddle the boundary between high costs and leakage. They can be bundled with . . .
