Not the Washington DC streetcar project, which at a cost of $1.5 billion is expected to raise land values by $5 to $7 billion. (This is the increase in value of “existing properties.” Double it to include the value of new construction.) So collecting just 30% of the increase should be sufficient to pay the cost.
A lot of details are missing from the source article, and so far I don’t know how to get the study which it describes.
Thanks for Alanna Hartzok for the tip.
