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 7,004 92373 residents, or 21.7%, live above that level. By land area, 28.9% of 92373 is above 55 dBA.

Noise by Part of 92373
Average noise levels for 92373 residents, grouped by direction from the center of 92373. The highest population-weighted average is in southwestern 92373; the lowest is in southeastern 92373, where just 13% of residents live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in the loudest section.

To the human ear, noise in southwestern 92373 sounds about 289% louder than in southeastern 92373, a 19.6 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-10 do you need to be?
I-10 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 quiet suburban street at night.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 8% of 92373 sits under tree canopy (lighter than most zip codes) and roughly 41% 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.

Rail Noise
Active freight rail runs through parts of 92373. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
How Noise Is Distributed Across 92373
The bar chart below shows the share of 92373 residents in each noise band. About 87% of residents live below the EPA's 55 dBA threshold, and roughly 1% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 92373 Compares
92373 sits the lowest among the peer group. Below: how 92373's average outdoor noise and share of residents above the EPA threshold compare with 92374, 92551, 92316, and 92508.
Average noise level (dBA)
92373's 51.1 dBA pop-weighted average is the lowest among the peer group. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than 92373 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 21.7% of 92373 residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 28.9% of 92373's footprint sits above 55 dBA, against a California average of 36.0% and a national average of 28.1%.
What This Means if You're Moving to 92373
- Distance from highways matters more than the neighborhood name. Two homes in the same zip code can differ by 20 dBA if one sits 100 meters from I-10 and the other 500 meters away. The model captures this at 100-meter resolution, so noise exposure changes block by block.
- Tree canopy can help reduce modeled noise exposure. Roughly 8% of 92373 is under tree cover (lighter than most zip codes), and the dominant land cover is low-intensity developed land. Both are measured from federal USDA Forest Service and USGS satellite imagery at 30-meter resolution. Streets with 60% or higher canopy show 3 to 5 dBA lower noise than comparable streets with bare ground or pavement, which is why the per-place decay rate above already accounts for it.
