This map shows modeled outdoor noise across Pacific Beach 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 11,756 Pacific Beach residents, or 40.8%, live above that level. By land area, 43.4% of Pacific Beach is above 55 dBA.

Noise by Part of Pacific Beach
Average noise levels for Pacific Beach residents, grouped by direction from the center of Pacific Beach. The highest population-weighted average is in eastern Pacific Beach; the lowest is in northern Pacific Beach, where just 25% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in eastern Pacific Beach sounds about 71% louder than in northern Pacific Beach, a 7.7 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 San Diego Fwy do you need to be?
San Diego Fwy 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 5% of Pacific Beach sits under tree canopy (lighter than most neighborhoods) and roughly 64% 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 Pacific Beach. 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.
Airport Noise
San Diego International (SAN) sits southeast of Pacific Beach. The U.S. Department of Transportation measures aviation noise around this airport directly, and the model uses those federal measurements rather than synthetic predictions.
Blocks under the approach and departure paths carry combined road-plus-aviation noise, with some exceeding 75 dBA on the map's Overall layer. Blocks on the opposite side of Pacific Beach, particularly to the northwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Pacific Beach
The bar chart below shows the share of Pacific Beach residents in each noise band. About 64% of residents live below the EPA's 55 dBA threshold, and roughly 11% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Pacific Beach Compares
Pacific Beach sits at the quieter end of the spectrum. Below: how Pacific Beach's average outdoor noise and share of residents above the EPA threshold compare with Serra Mesa, Clairemont Mesa, City Heights East, and Loma Portal.
Average noise level (dBA)
Pacific Beach's 54.2 dBA pop-weighted average is at the quieter end of the spectrum. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Pacific Beach because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 40.8% of Pacific Beach residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's in the middle of its peer group. Measured by land area instead, 43.4% of Pacific Beach'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 Pacific Beach
- 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 San Diego Fwy 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 5% of Pacific Beach is under tree cover (lighter than most neighborhoods), and the dominant land cover is medium-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.
- Airport noise is directional. San Diego International's approach paths concentrate aviation noise to the southeast. Neighborhoods to the northwest of downtown show no measurable contribution from the airport.
