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 6,515 Lakeview Terrace residents, or 45.2%, live above that level. By land area, 46.6% of Lakeview Terrace is above 55 dBA.

Noise by Part of Lakeview Terrace
Average noise levels for Lakeview Terrace residents, grouped by direction from the center of Lakeview Terrace. The highest population-weighted average is in western Lakeview Terrace; the lowest is in eastern Lakeview Terrace, where just 37% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.

Normal conversation an arm’s length away
To the human ear, noise in western Lakeview Terrace sounds about 78% louder than in eastern Lakeview Terrace, a 8.3 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-210 do you need to be?
I-210 produces an estimated 78 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 3% of Lakeview Terrace sits under tree canopy (much lighter than most neighborhoods) and roughly 44% 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.

Airport Noise
Bob Hope (BUR) sits south of Lakeview Terrace. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, 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 65 dBA on the map's Overall layer. Blocks on the opposite side of Lakeview Terrace, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Lakeview Terrace
The bar chart below shows the share of Lakeview Terrace residents in each noise band. About 57% of residents live below the EPA's 55 dBA threshold, and roughly 19% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Lakeview Terrace Compares
Lakeview Terrace sits at the quieter end of the spectrum. Below: how Lakeview Terrace's average outdoor noise and share of residents above the EPA threshold compare with Crescenta Highlands, Garnsey, Citrus Grove, and Grandview.
Average noise level (dBA)
Lakeview Terrace's 56.6 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 Lakeview Terrace because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 45.2% of Lakeview Terrace 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, 46.6% of Lakeview Terrace'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 Lakeview Terrace
- 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-210 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 3% of Lakeview Terrace is under tree cover (much 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. Bob Hope's approach paths concentrate aviation noise to the south. Neighborhoods to the north of downtown show no measurable contribution from the airport.
