This map shows modeled outdoor noise across 79248 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 96 79248 residents, or 16.8%, live above that level. By land area, 5.3% of 79248 is above 55 dBA.

Noise by Part of 79248
Average noise levels for 79248 residents, grouped by direction from the center of 79248. Central 79248 carries the highest population-weighted average; Western 79248 carries the lowest. Just 0% of residents in Western 79248 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Central 79248.

Central 79248 sounds about 162% louder than Western 79248 to the human ear, a 13.9 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 do you need to be?
produces an estimated 61 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 1% of 79248 sits under tree canopy (much lighter than most zip codes) and roughly 26% 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.
