This map shows modeled outdoor noise across Red Lick 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 55 Red Lick residents, or 6.4%, live above that level. By land area, 16.2% of Red Lick is above 55 dBA.

Noise by Part of Red Lick
Average noise levels for Red Lick residents, grouped by direction from the center of Red Lick. Southern Red Lick carries the highest population-weighted average; Western Red Lick carries the lowest. Just 5% of residents in Western Red Lick live in blocks above the EPA's 55 dBA threshold, about half the share in Southern Red Lick.
Northern Red Lick
3% of people above 55 dBA
Southern Red Lick
13% of people above 55 dBA
Western Red Lick
5% of people above 55 dBA
Southern Red Lick sounds about 46% louder than Western Red Lick to the human ear, a 5.5 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 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 37% of Red Lick sits under tree canopy (about average for 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.
