This map shows modeled outdoor noise across Skyland Park at 100-meter resolution, combining road, aviation, and rail sources. Green areas measure below 45 dBA. Orange and red exceed the EPA's 55 dBA outdoor threshold linked to long-term health effects. Use the layer toggles to view each source on its own or all together.

Population Above the EPA Outdoor Threshold
The EPA's 55 dBA outdoor reference level is a common benchmark for residential noise exposure, especially for activity interference, annoyance, and long-term community noise concerns. About 607 Skyland Park residents, or 19.0%, live above that level. By land area, 31.3% of Skyland Park is above 55 dBA.

Noise by Part of Skyland Park
Average noise levels for Skyland Park residents, grouped by direction from the center of Skyland Park. Southern Skyland Park carries the highest population-weighted average; Northern Skyland Park carries the lowest. Just 15% of residents in Northern Skyland Park live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in Southern Skyland Park.
Central Skyland Park
14% of people above 55 dBA
Eastern Skyland Park
14% of people above 55 dBA
Northern Skyland Park
15% of people above 55 dBA
Southern Skyland Park
28% of people above 55 dBA
Western Skyland Park
18% of people above 55 dBA
Southern Skyland Park sounds about 31% louder than Northern Skyland Park to the human ear, a 3.9 dBA gap. Every 10 dBA roughly doubles perceived loudness. Within any of these directions, two homes a quarter mile apart can still differ by 10 or more dBA depending on how close they sit to a major highway.
How far back from Goverment Blvd do you need to be?
Goverment Blvd produces an estimated 66 dBA at its loudest centerline points. Noise drops logarithmically with distance, with the exact rate depending on what's between you and the road. Tree cover, walls, terrain, and pavement type all matter. At roughly a quarter mile back, traffic fades into the noise level of a soft rainfall.
Calculated from the model's calibrated attenuation formula. About 53% of Skyland Park sits under tree canopy (much heavier than most neighborhoods) and roughly 22% is impervious surface like pavement and rooftops. Both are folded into the per-place decay rate above. Heavier canopy pulls noise down faster with distance; impervious surfaces slow the drop.
