First, it was once called, somewhat more accurately, an "economic impact analysis," given that the ESDC was willing to consider some public contributions and thus not simply tote up new revenues. Second, the ESDC once mentioned the value of public improvements and infrastructure.
More importantly, the "economic impact analysis" was never a full cost-benefit analysis, given that it looked at public costs and subsidies quite narrowly.
Comparing the documents
As noted in the graphic above right, from the 2006 Modified General Project Plan, the ESDC was once willing to calculate certain numbers. For example, the "direct personal income related to construction activities" no longer appears in the 2009 document (at left); only the "total personal income."
More importantly, in the 2006 document, the ESDC calculated not only total tax revenues (nearly $1.4 billion) over 30 years, in present value, but net tax revenues of $944.2 million "in excess of the public contribution to the project." No net tax revenue figure is now calculated.
Now the office space is in severe doubt. Indeed, in an Appendix to the Technical Memorandum issued in June, the ESDC addressed a "Delay of Building 1 Scenario," which noted impacts on the Urban Room (replaced by an urban plaza), impacts on arena operation, and impacts on urban design, traffic, air quality, and noise. The conclusion was that no Supplemental Enviornmental Impact Statement (SEIS) is needed.
How does that affect the "Economic Benefit Analysis"? The ESDC ignored that issue.
Shouldn't the ESDC provide a range of estimates, based on a full buildout of the project and multiple scenarios for delays? In that June memo, the ESDC acknowledged that “the delay of the full build out of the project would result in a delay in the realization of the full economic benefits of the project as disclosed in the FEIS.”
There was no follow-up.
In the new document, the ESDC does not, at least in the section regarding economic impact, mention the "public improvements and infrastructure." In the 2006 MGPP, the sum was $554 million. Elsewhere in the 2009 board document, the sum is $717 million.
Why was it omitted? Perhaps because one component of such improvements, the planned replacement railyard, would be smaller than once projected and, despite inflation, likely worth less.
