This map shows modeled outdoor noise across Enterprise 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 1,817 Enterprise residents, or 31.1%, live above that level. By land area, 51.1% of Enterprise is above 55 dBA.

Noise by Part of Enterprise
Average noise levels for Enterprise residents, grouped by direction from the center of Enterprise. The highest population-weighted average is in western Enterprise; the lowest is in northeastern Enterprise, where just 21% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.
Western Enterprise
71% of people above 55 dBA
Southern Enterprise
29% of people above 55 dBA
Central Enterprise
16% of people above 55 dBA
Northern Enterprise
21% of people above 55 dBA
Northeastern Enterprise
21% of people above 55 dBA
To the human ear, noise in western Enterprise sounds about 157% louder than in northeastern Enterprise, a 13.6 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-5 do you need to be?
I-5 produces an estimated 77 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 13% of Enterprise sits under tree canopy (about average for neighborhoods) and roughly 36% 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.
