This map shows modeled outdoor noise across Faith 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 123 Faith residents, or 11.5%, live above that level. By land area, 14.2% of Faith is above 55 dBA.

Noise by Part of Faith
Average noise levels for Faith residents, grouped by direction from the center of Faith. Western Faith carries the highest population-weighted average; Northern Faith carries the lowest. Just 9% of residents in Northern Faith live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Western Faith.
Central Faith
12% of people above 55 dBA
Eastern Faith
4% of people above 55 dBA
Northern Faith
9% of people above 55 dBA
Southern Faith
17% of people above 55 dBA
Western Faith
14% of people above 55 dBA
Western Faith sounds about 41% louder than Northern Faith to the human ear, a 5.0 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 SR-1006 do you need to be?
SR-1006 produces an estimated 59 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 46% of Faith 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.
