This map shows modeled outdoor noise across Citrus Grove 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 11,061 Citrus Grove residents, or 77.0%, live above that level. By land area, 80.9% of Citrus Grove is above 55 dBA.

Noise by Part of Citrus Grove
Average noise levels for Citrus Grove residents, grouped by direction from the center of Citrus Grove. The highest population-weighted average is in northern Citrus Grove; the lowest is in western Citrus Grove, where just 73% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.

Normal conversation an arm’s length away
To the human ear, noise in northern Citrus Grove sounds about 185% louder than in western Citrus Grove, a 15.1 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 Ventura Fwy do you need to be?
Ventura Fwy produces an estimated 80 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 2% of Citrus Grove sits under tree canopy (much lighter than most neighborhoods) and roughly 76% 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 northwest of Citrus Grove. 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 Citrus Grove, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Citrus Grove
The bar chart below shows the share of Citrus Grove residents in each noise band. About 20% of residents live below the EPA's 55 dBA threshold, and roughly 34% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Citrus Grove Compares
Citrus Grove sits at the louder end of the spectrum. Below: how Citrus Grove's average outdoor noise and share of residents above the EPA threshold compare with Mariposa, Atwater Village, Grandview, and Crescenta Highlands.
Average noise level (dBA)
Citrus Grove's 58.4 dBA pop-weighted average is at the louder end of the spectrum. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Citrus Grove because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 77.0% of Citrus Grove residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 80.9% of Citrus Grove'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 Citrus Grove
- 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 Ventura 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 2% of Citrus Grove 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 northwest. Neighborhoods to the southeast of downtown show no measurable contribution from the airport.
