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 1,215 Coeur D'Alene Place residents, or 25.5%, live above that level. By land area, 23.7% of Coeur D'Alene Place is above 55 dBA.

Central Coeur D'Alene Place sounds about 21% louder than Northern Coeur D'Alene Place to the human ear, a 2.7 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 Courcelles do you need to be?
Courcelles produces an estimated 57 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 6% of Coeur D'Alene Place sits under tree canopy (lighter than most neighborhoods) and roughly 39% 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.
