Currently the PTIAA is trying to use the 65DNL (65Db Day Night Level) for
their estimates of how many people will be affected by the hub. Both the
EPA and WHO say that residences, schools, and hospitals should not be built
in 55 DNL and above. And for nighttime noise the numbers should be
even lower. PTIAA and the Federal Aviation Administration claim that the
65DNL is the standard that should be used for compensation. In fact, only
homes in the 70DNL will be eligible for buyout, and those in the 65DNL will
only receive money for "soundproofing" their houses. According to their
estimates, only a handful of homes will be eligible for buyout or
compensation.
If you use the 55DNL as recommended by both the Environmental
Protection Agency and the World Health Organization the number
jumps to over 10,000 homes affected. At an average of 3.2 people per home,
that's 32,000 people affected that should be eligible for some sort of
compensation - at taxpayers expense. (In Louisville, Kentucky the
noise mitigation costs have exceeded original estimates by over one billion
taxpayer dollars, and the buyout is still going on over a decade after the
fact.) Keep this in mind as our Guilford County Commissioners are already
discussing raising your taxes to make up for the current budget shortfall.
Notes: On the map below, we put a red line over the black dots representing the 55DNL contours to make it easier to pick it out from the others. The 65DNL and the 70DNL lines are closer in to the airport. To get an idea of what areas will be affected when FedEx flies in from the other direction, flip the 55 DNL line around so it's pointing the other direction.
