Doing Projects Right and Doing the Right Project
I’d like to develop a distinction between two modes of success or failure in infrastructure projects, which I’ve mentioned in brief in past post. An infrastructure project may be done right or wrong – that is, it could be built at a reasonable lifecycle cost and offer high quality of service or it could fail to do this, typically through very high upfront construction costs with no future benefit. But it could also be the right project to build or the wrong one – that is it could be the right priority for the region that builds it based on expected usage and future development or it could be a low priority, typically due to politicization of engineering and planning. Those are distinct judgments, and I’m not even sure they are strongly correlated.
The right project, done wrong
I’ve mentioned in a few past posts as well as videos that New York is for the most part building the right projects right now. Based on any reasonable cost per rider calculation, the highest priorities in the region excluding mainline rail are Second Avenue Subway phases 1 and 2, an extension of phase 2 under 125th Street, subway extensions under Nostrand and Utica Avenues, an orbital line following the Bay Ridge Branch toward Jackson Heights and Yankee Stadium, and a subway extension to LaGuardia Airport. Phase 1 has been built, and the current priorities are phase 2 and the orbital line under the moniker IBX, the latter giving the governor’s personal imprimatur to this important project. The only lower-priority extension built ahead of these is the 7 extension to Hudson Yards, which is a small fraction of the good projects by total cost.
In mainline rail, on the New Jersey side, the biggest priority is the Gateway tunnel and this is indeed what the state and Port Authority are most invested in. Even on the New York side, mainline rail is invested in in roughly the right priority order, especially if one fixes the assumption of bad present-day operations; the only real problem is that due to politics from the late 1990s, the MTA overinvested in New York-side mainline rail (that is, East Side Access) to secure suburban Republican support for Second Avenue Subway phase 1.
The problem for New York is that every single project it touches is executed in almost the worst way possible. It can’t build, and to an extent it doesn’t even want to build. The $50 billion in New York-side capital investment every five years are a large multiple of what peer cities spend, and what this buys is a few kilometers of subway every decade, escalating maintenance costs, and a vague promise to not quite finish making the subway accessible in the 2050s. But the little it does build is, for the most part, the right project.
New York is not the only city in this situation. The prioritization in Toronto seems fine to me, including the Downtown Relief Line rebranded as the Ontario Line, electrification and general modernization of commuter rail as part of the RER project, and rail on Eglinton. London, likewise, seems to be building projects in the right priority order, but it lost its ability to build in the 1980s and 90s so that its urban rail growth rate is roughly one new line per monarch and its step-free access program is proceeding at a slower pace than that of any peer except New York (which can’t build anything) and Paris (which can and does but doesn’t believe in accessibility).
Wrong projects
In contrast with the example of New York or Toronto, there are places where the prioritization is completely out of whack. The best example I can give of is Los Angeles. Like New York and other English-speaking cities, Los Angeles can’t build; unlike New York, it clearly wants to build, and has a large expansion program based on two separate sales tax referenda, with lines programmed through the 2060s due to the extreme construction costs. However, the capital prioritization is just wrong, in several ways:
- The priority list puts low-usage extensions to the suburbs, like the Foothills Extension of the Gold Line and the West Santa Ana Branch, above core lines replacing high-usage buses like South Vermont and connectivity projects like linking Burbank and Pasadena directly.
- The suburban extensions often use the wrong mode or alignment – Los Angeles loves freeway medians for light rail rights-of-way, is building some lines parallel to or even in the right-of-way of commuter rail in lieu of improving Metrolink, and was starting to run into capacity problems on the shared street-running section of the Expo and Blue Lines before corona even on an otherwise low-intensity system.
- There is no transit-oriented development plan – the region is likely the NIMBY capital of the United States, and perhaps the developed world, with large swaths of valuable near-center land that’s about to get subway stations that’s still zoned single-family; in the state legislature, YIMBY bills increasing housing production typically get a large majority of the votes of politicians representing the Bay Area and a small minority of those representing the Los Angeles region.
- Much of the referendum money is not even rail expansion, but road programs, including new freeway lanes.
The upshot is that while New York builds the right projects wrong, Los Angeles builds the wrong projects, besides its issue of very high construction costs.
In reality, most places are on a spectrum, or even evolve from one to the other based on political changes. San Francisco built the almost totally useless Central Subway due to demands by people in Chinatown who don’t even ride public transportation; the line is so short and deep that even ignoring its construction costs, its trip time benefit over the buses it’s replacing is maybe 30 seconds. However, the future projects it wants to build but can’t due to high costs – the Downtown Extension tunnel taking Caltrain from its present near-center terminus to the actual city center and a second BART tube across the Bay with an extension under Geary – are exactly the right priorities, and would have long been built anywhere that could tunnel for $250 million/km and not $1 billion/km.
Boston, likewise, is building the right priorities at the level of what lines are visible on the map, but it has the second of Los Angeles’s four problems in droves. The Green Line Extension should have been commuter rail; the commuter rail electrification project should be all-catenary and not the current plan of a combination of catenary and experimental battery technology; the deelectrification of the trolleybuses was just embarrassing. But the actual alignments – the Green Line Extension, the planned Red-Blue Connector, and the Regional Rail project – are the right priorities, at least.
The wrong project, done right
So far I’ve given American examples of poor construction practices. But there are also examples of places that build effectively but have poor prioritization. My own city, Berlin, is the best example I can think of: its construction costs are pretty average – higher than in Southern Europe, lower than anywhere that uses international English-dominant consultants – but its project prioritization is terrible.
The obviously lowest-cost-per-rider extension, that of U8 to Märkisches Viertel (see some references linked here), has been deprioritized due to bad politicking. The Green Party and the heir to the East German communist party, Die Linke, both oppose subway construction on ideological grounds and prefer trams, the Greens because they associate subway construction with making room on the surface for cars and Die Linke for a combination of being used to East German trams and general wrecker politics. In the outgoing coalition, the pro-subway Social Democrats pushed for the lines that were the most important for its own priorities and those happen to be in Spandau and at the airport rather than Märkisches Viertel; thus, the U8 extension was placed behind those.
As with the American examples in the previous two sections, here we must qualify judgment in that it’s rather common for cities to be on a spectrum. Even Berlin has better project prioritization than Los Angeles: for one, it is not as NIMBY, and the U7 airport extension does come with a transit-oriented development plan.
A more typical example is perhaps Paris. Paris’s project prioritization raises some questions, but there is no obviously low-hanging fruit like U8 that remains unbuilt due to East Germany and 1970s New Left dead-enders. The current expansion plans underrate core capacity, by which I mean separating the RER B and D tunnels, currently shared between Gare du Nord and Châtelet-Les Halles; but such a project would be disruptive if highly beneficial, and another core capacity project, namely the expansion of the RER E through the city to La Défense and western suburbs, is proceeding. The outward expansion of the Métro seems to be largely in line with what the most important priorities are; Grand Paris Express is a mix of good lines, that is Métro Lines 14, 15, and 16, and bad that is Line 17 to the airport and Line 18 linking two rich suburbs with little density in-between.
Moreover, the Paris suburbs, where practically all expansion is done, are fairly YIMBY. Francilien housing production in the late 2010s was 80,000-90,000 a year (in 2019 it was 82,000, or 6.7/1,000 people), with virtually no construction in the city proper – and moreover, the housing built in the suburbs tends to be infill replacing disused industrial land, or else it’s on top of planned Grand Paris Express or RER stations.
Why?
The poor project prioritization in the cities I’ve given the most attention to – Los Angeles but also Berlin and San Francisco and glimpses of Paris and New York – is entirely about politics. As the worst city of the bunch, Los Angeles has illuminating features that we can use to judge the others.
In Southern California, the most significant misfeature is the statewide requirement that all tax increases be approved in a referendum by a two-thirds majority. In San Francisco, the electorate is so left-wing that this hurdle is not hard to clear, and agencies can plan as always. In Los Angeles and San Diego, it is not, and to secure enough votes, agencies have to essentially bribe clientelistic actors with specific lines on a map that those actors will never use but still take credit for. This leads to all of the following misfeatures:
- Ballot propositions that include not just expansion of the rail network but also subsidies to reduced fares for people with local New Left politics who identify politically against state planning, road expansion money for local notables who don’t mind rail expansion but think it’s too political to prioritize rail over cars, and long-term maintenance for unambitious bureaucrats who love spending that isn’t expected to produce concrete results.
- An expansion program that gives each subregion its own line – in Los Angeles, this is the Orange Line BRT for the Valley, the Gold Line for San Gabriel Valley, and so on; the core is a subregion in its own right and can get a project too, like the Regional Connector subway, but it can’t be expected to get too many projects, and interregional connections are less important since the regions they serve already have their lines.
- The planning is haphazard and avoids paradigmatic changes like modernizing the commuter rail system – Los Angeles has some advocates pushing for electrification, like Paul Dyson, and long-term plans to actually do it, but those plans are far behind what Caltrain electrification in the Bay Area (a perfect example of the right project done wrong) and what technical advocates are doing in Philadelphia and Boston.
In effect, a constitutional change intended to prevent California from wasting taxpayer money has had the opposite effect: the two-thirds majority requirement for tax hikes ensures that in Southern California, every petty actor is a veto point and therefore can get extra money. The New Left may comprise 1970s dead-enders trying and failing to reconcile their NIMBYism with the challenges of the 21st century, but it’s the New Right that destroyed the ability of the state to build anything.
With this in mind, we can look at the deviations in Berlin, San Francisco, and New York through the same lens. Berlin lacks any kind of New Right veto point system for investment; a majority in the Abgeordnetenhaus is sufficient, and its typical party of government, SPD, has decently developmental and YIMBY views, hobbled just now by an atypically bad leader and federal headwinds. However, the coalitions it’s in require it to provide sops to either NIMBYs (that is, the Greens) or drivers (that is, CDU). The outgoing all-left coalition deprioritized the U-Bahn to build trams, while the incoming CDU-SPD coalition wants U-Bahns but with park-and-rides and cessation of road diet programs. The difference is that the system in Los Angeles requires agencies to offer sops to both groups at once in addition to others.
One of the other actors, not present in Berlin beyond their influence on CDU, is the local notables. These are typically business owners, who as a constituency drive and overestimate the share of their customers who drive. In the United States (but not France or Germany) they may also trade on an ethnically marked identity, which is usually local and pro-car again since the (say) Chinese-Californians who take the train are usually Downtown San Francisco workers who socialize outside the neighborhood. The Central Subway was specifically a demand of such interests from Chinatown, who had opposed the removal of the Embarcadero Freeway and demanded something that would look like a replacement, and in a way is, in the sense that neither the freeway nor the Central Subway is of any use for urban travel. Here, the difference with drivers as an interest is that drivers want more car infrastructure that feels to them like it makes their trips more convenient, whereas local notables want to be seen extracting money from the city or state to prove to their clients that they are powerful; for the notables, the cost is itself the benefit.
Excessive empowerment of local notables – that is, any empowerment – leads to both poor project prioritization and high costs. I don’t think there’s a high correlation between the two judgments, but it’s telling that the best example I know of of bad prioritization is high-cost Los Angeles, while medium-cost Berlin is much less bad. The other political mechanisms seem independent of costs: a system in which the state and developmental interests are hobbled by NIMBYism or by actors who want to annoy Greta Thunberg will underbuild or build the wrong things, but NIMBYs rarely manage to meaningfully raise costs and were entirely absent from any of the mechanisms we’ve found for high costs in our New York and Boston reports.
