This map is just TOO LARGE to post, so I will have to leave a link.
Link to the RDU site page for Composite Noise Corridor maps. Click the links under Noise Disclosure.
The original size of the map is 90 inches x 35 inches. That allows the RDU Airport Noise folks to give us detail right down to street level, as to what subdivisions may be affected by air traffic noise.
The good folks at Staples Print Center estimated I would pay about $220 for a printed and laminated copy.
And the map extends from the north and west side of Apex to Cary and Morrisville, and well into Durham County and North Raleigh and northern Wake County.
It is the most up to date rendering, having been released in January 2010.
As a bonus, it clears up a lot of mystery regarding the proximity of the 540 freeway project to subdivisions and area features.
