This map shows modeled outdoor noise across 92557 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 16,812 92557 residents, or 33.1%, live above that level. By land area, 33.5% of 92557 is above 55 dBA.

Noise by Part of 92557
Average noise levels for 92557 residents, grouped by direction from the center of 92557. Southern 92557 carries the highest population-weighted average; Central 92557 carries the lowest. Just 15% of residents in Central 92557 live in blocks above the EPA's 55 dBA threshold, about half the share in Southern 92557.

Eastern 92557
36% of people above 55 dBA
Northern 92557
22% of people above 55 dBA
Southern 92557
37% of people above 55 dBA
Western 92557
40% of people above 55 dBA
Southern 92557 sounds about 54% louder than Central 92557 to the human ear, a 6.2 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 State Rte 60 do you need to be?
State Rte 60 produces an estimated 79 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 4% of 92557 sits under tree canopy (much lighter than most zip codes) and roughly 39% 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.
