This map shows modeled outdoor noise across Neskowin 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 46 Neskowin residents, or 15.5%, live above that level. By land area, 24.3% of Neskowin is above 55 dBA.

Noise by Part of Neskowin
Average noise levels for Neskowin residents, grouped by direction from the center of Neskowin. Central Neskowin carries the highest population-weighted average; Eastern Neskowin carries the lowest. Just 1% of residents in Eastern Neskowin live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Central Neskowin.
Central Neskowin
67% of people above 55 dBA
Eastern Neskowin
1% of people above 55 dBA
Northern Neskowin
12% of people above 55 dBA
Southern Neskowin
13% of people above 55 dBA
Western Neskowin
33% of people above 55 dBA
Central Neskowin sounds about 101% louder than Eastern Neskowin to the human ear, a 10.1 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 US Route 101 do you need to be?
US Route 101 produces an estimated 62 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 45% of Neskowin sits under tree canopy (heavier than most cities) and roughly 6% 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.
