This map shows modeled outdoor noise across Chimney Lakes 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 16,561 Chimney Lakes residents, or 96.2%, live above that level. By land area, 97.6% of Chimney Lakes is above 55 dBA.

Noise by Part of Chimney Lakes
Average noise levels for Chimney Lakes residents, grouped by direction from the center of Chimney Lakes. Western Chimney Lakes carries the highest population-weighted average; Eastern Chimney Lakes carries the lowest. Just 91% of residents in Eastern Chimney Lakes live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Western Chimney Lakes.

Western Chimney Lakes sounds about 55% louder than Eastern Chimney Lakes to the human ear, a 6.3 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 First Coast Expwy do you need to be?
First Coast Expwy produces an estimated 73 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 21% of Chimney Lakes sits under tree canopy (heavier than most neighborhoods) and roughly 34% 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.
