I live in one such place: a medium sized development(72 single family homes), that is basically a connected set of cul-de-sacs. The development is called "Oakbridge Forest"

'Oakbridge' is a blending of the names of two nearby neighborhoods: Oak Grove, and Great Bridge... 'Forest' comes from the fact that the developer made the conscious decision not to cut down all the trees.

I'm more curious, however, about how my particular cul-de-sac got its name: "Sandcastle Court"... not a beach in sight. Though I don't mind -- as a semi-pro writer specializing in fantasy, it fits like a glove.

"Sandcastle Court" in the "Oakbridge Forest". Sounds like I should be an elf or something...
