How old is the satellite view? Has anybody been by there recently? I'll admit I looked at the brochure and it (Quay Valley) looks like [vaporware].
Plus I'm just a bit perturbed with these must-be-generated-by-an-algorithm locational names. A quay is a wharf (http://en.wikipedia.org/wiki/Wharf). And the only water around is coming out of a pipe. And a "Quay Valley" is some sort of malapropism, especially in geographic context.
