This map shows modeled outdoor noise across 95360 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 3,043 95360 residents, or 24.4%, live above that level. By land area, 22.2% of 95360 is above 55 dBA.

Noise by Part of 95360
Average noise levels for 95360 residents, grouped by direction from the center of 95360. The highest population-weighted average is in eastern 95360; the lowest is in northwestern 95360, where just 3% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.
Eastern 95360
22% of people above 55 dBA
Central 95360
13% of people above 55 dBA
Western 95360
13% of people above 55 dBA
Southwestern 95360
9% of people above 55 dBA
Northwestern 95360
3% of people above 55 dBA
To the human ear, noise in eastern 95360 sounds about 53% louder than in northwestern 95360, a 6.1 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 I-5 do you need to be?
I-5 produces an estimated 76 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 95360 sits under tree canopy (much lighter than most zip codes) and roughly 43% 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.
