§ I · The surface
Picture a ranch off McGavock Pike.
A modest ranch off McGavock Pike. Quiet street, big lot, the kind of value that's become rare inside the I-440 loop. The seller had owned it for thirty-one years.
§ II · The hidden layer
BNA's approach envelope reaches across some Donelson lots and stops short of others a few hundred feet away. The CSX freight line runs within range of much of the neighborhood. Whether either crosses your specific lot — or stops one row over — is the question.
§ III · What the records show
Representative findings within range of typical Donelson addresses:
BNA approach
partial coverage
Active USTs ≤ 1 mi
avg 7
TRI facilities
4 within 2 mi
Rail proximity
CSX ≤ 500 m
§ IV · The bottom line
Aviation and freight are the defining factors. Specific streets fall closer to the BNA approach envelope; immediately adjacent ones don't.
