For years, Arlington, VA, has been seen as an example of sensible, transit-oriented planning, and many of the residential and commercial projects within its boundaries that accommodate transit users are nationally recognized. However, the once unified coalition of smart growth proponents is coming undone by, of all things, a proposed streetcar. Much of the trouble stems from one newly elected local boardmember who has criticized the $300 million project for siphoning funds that could be used for other needs or at least a lower-cost busway. The sudden existence of a streetcar opponent at the municipal government level has enabled those with other grievances to come out of the woodwork and assail the project and the perceived political patronage that opponents believe has allowed smart growth ideas to flourish in Arlington. Some of the criticism is at least attached to the belief that streetcars lead to revitalized communities, a claim that is in dire need of further research and scientific validation.
