This map shows modeled outdoor noise across Sunset 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 1,097 Sunset residents, or 31.1%, live above that level. By land area, 31.1% of Sunset is above 55 dBA.

Noise by Part of Sunset
Average noise levels for Sunset residents, grouped by direction from the center of Sunset. Western Sunset carries the highest population-weighted average; Eastern Sunset carries the lowest. Just 32% of residents in Eastern Sunset live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Western Sunset.
Central Sunset
21% of people above 55 dBA
Eastern Sunset
32% of people above 55 dBA
Northern Sunset
23% of people above 55 dBA
Southern Sunset
43% of people above 55 dBA
Western Sunset
47% of people above 55 dBA
Western Sunset sounds about 27% louder than Eastern Sunset to the human ear, a 3.4 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 Fordham Ci do you need to be?
Fordham Ci produces an estimated 55 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 3% of Sunset sits under tree canopy (much lighter than most neighborhoods) and roughly 47% 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.
