Notes:
a
Values provided are cumulative from the core area to the > 60 DNL contour.
b
A population estimate was determined from the number of residences, where the number of residences was
multiplied by 3 people per household (the average number of people per household for all of the U.S. Census
Block Groups that overlay the 60 DNL for all potential additional OLF sites).
c
Numbers based on GIS analysis only.
d
Land parcel data was summarized because landowner data were not available; the number of landowners
was counted for the core area and a ratio of parcels to landowners was used to estimate the number of
landowners in the noise contours (number of landowners are in parenthesis).
e
Values do not include the number of landowners in NC.
f
The percentage for the core area was based on a 2,003-acre area; the percentage for the >60 DNL noise
contour was calculated from the total area of the >60 DNL contour, approximately 24,000 acres.
