This map shows modeled outdoor noise across Chestnut Ridge 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 55 Chestnut Ridge residents, or 12.4%, live above that level. By land area, 24.0% of Chestnut Ridge is above 55 dBA.

Noise by Part of Chestnut Ridge
Average noise levels for Chestnut Ridge residents, grouped by direction from the center of Chestnut Ridge. Central Chestnut Ridge carries the highest population-weighted average; Western Chestnut Ridge carries the lowest. Just 7% of residents in Western Chestnut Ridge live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Central Chestnut Ridge.
Central Chestnut Ridge
36% of people above 55 dBA
Eastern Chestnut Ridge
11% of people above 55 dBA
Northern Chestnut Ridge
13% of people above 55 dBA
Southern Chestnut Ridge
0% of people above 55 dBA
Western Chestnut Ridge
7% of people above 55 dBA
Central Chestnut Ridge sounds about 36% louder than Western Chestnut Ridge to the human ear, a 4.4 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 Ci9z Center Gas Rd do you need to be?
Ci9z Center Gas Rd produces an estimated 58 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 47% of Chestnut Ridge sits under tree canopy (heavier than most cities) and roughly 7% 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.
