In many plans, newspaper articles and press releases dealing with redevelopment/regeneration in Buffalo, the term "shovel ready" is almost always mentioned. A "shovel ready" site apparently means a once-occupied but now vacant lot with no encumbrances to development; it's not a greyfield or brownfield that requires any remediation.
I have never heard "shovel ready" used in a context that doesn't relate to Buffalo. Did the term start in Buffalo? Is it used elsewhere?
