This map shows modeled outdoor noise across 76255 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 510 76255 residents, or 15.2%, live above that level. By land area, 15.5% of 76255 is above 55 dBA.

Noise by Part of 76255
Average noise levels for 76255 residents, grouped by direction from the center of 76255. Western 76255 carries the highest population-weighted average; Eastern 76255 carries the lowest. Just 1% of residents in Eastern 76255 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Western 76255.
Eastern 76255
1% of people above 55 dBA
Northern 76255
10% of people above 55 dBA
Southern 76255
16% of people above 55 dBA
Western 76255
22% of people above 55 dBA
Western 76255 sounds about 93% louder than Eastern 76255 to the human ear, a 9.5 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 70 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 5% of 76255 sits under tree canopy (lighter than most zip codes) and roughly 20% 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.
