Or how some streetcar advocates make their case by using the Iraq war’s lobbyists strategy.
Such strategy is not to be embarrassed with facts, but to express an opinion legitimated by an ample corpus of previously expressed opinions, which are presented as facts. It becomes then a mythology, because it is asked to people to believe unquestionably in them. and if it succeed at it, the unsubstantiated “facts” become “truisms”!
The streetcar example with a report : Streetcar Land Use Study
It is a report commissioned and published by the Planning department of the District of Columbia- so must be serious (We refer to it as “the report”)- which explains that a Washington D.C. streetcar network could generate $15Billion of investment along its corridors.
How it arrives to such a conclusion?
Basically it is grounded on a Portland streetcar company‘s paper , analyzing the real estate development in the years 1997-2008, which eventually happens to coincide with a global real estate boom, and general gentrification of cities’ downtown across the continent.
In addition of the global factors above, it has been also some more local factor attracting development in Portland:
- A green belt constraining the development area
- Other transit development (3 max line, an aerial tram…), all converging in downtown
- Insitutional development 
- Tax credit 
- A street car loop
What is the exact contribution of the streetcar loop among the above cited parameters? It is not deciphered by the Washington D.C. study, apparently considering that the entirety of the developments occurring in the 2 blocks of the streetcar are triggered by virtue of its track presence.
What are the inherent quality of the streetcar provoking that?
The report describes it as a “Premium transit” transit service that is “reliable, predictable, and offers a high-quality ride—in other words, Metrorail [Note: the DC subway] or the streetcar“.
What about speed and frequency? does it really doesn’t matter? …and in what aspect a streetcar operating in mixed traffic can be more reliable-or predictable- than a bus?
What are the involved cost of the streetcar?
The venture of the report in this area is rich of learning. It states that: “Evidence [...] suggests that streetcar vehicles offer better long-term cost-benefit value than buses”. Where are the evidence? 2 references are cited:
- Street Smart: Streetcars and Cities in the Twenty-First Century – Gloria Ohland & Shelley Poticha; 2009
- Seven Rules for Sustainable Communities from Patrick Condon 
It is worth to mention, that, first the conclusions of Patrick Condon are grounded on the finding of the other referenced book, and secondly,  presents numbers which should be subject to caution .
Circular referencing, but no cross checking…That was also the strategy of the Iraq war lobbyist
In anyway, a blanket statement like “streetcar vehicles offer better long-term cost-benefit value than buses” is discounting too many parameters to be taking seriously: one of them is that the long-term cost-benefit of a vehicle is tied to its productivity, which depend in part of the ridership.
What about other alternatives
The bus alternative is briefly investigated to be better dismissed: “Although well-designed BRT systems attract some development, their impacts are typically much less than those for rail”, this by citing  where one will have hard time to find which aspect of  leads the report to such a conclusion. In fact  suggests that “there is growing documentation of [BRT] positive development effects; however, given the newness of most BRT systems, more information is needed” while another  find that “the type and level of investment occurring near BRT stations appears comparable to the experience with TOD near rail transit”. Notice that this later reference provides relevant number:
“Since the Silver Line BRT was introduced, there has been over $571 million in investment along this corridor, and the tax base grew by 247%, compared to a city average of 146%. “
Relative growth on tax base in the corridor versus average… The Kind of information the streetcar report fails to provide.
And, outside transportation… does there is no other cost-effective avenue to shape development? Institutional impetuous as seeing in Surrey BC, seems to produce good effect, other large scale development like the Woodward building in Vancouver also…
Like in any mythology, with the streetcar mythology, facts are second to beliefs. The Streetcar myth just needs a critical mass of believers. If enough developers and buyers believe in it, the prophecy will be self fulling…that is why all the produced literature referencing itself is paramount.
Vancouver’s believer will then ask the question as Gordon Price did: “why not at least a return of the heritage tram to Science World?“, but the question shouldn’t be framed like it, it should be
- “what you want to try to achieve by returning the heritage tram to Science World?”
 Numerous of land lots, developed around the streetcar, are or were institutional, and a 10 years property tax waiver has been put in place to “faciliate” development in the streetcar corridor(source: )
