This map shows modeled outdoor noise across Mansion View 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 5 Mansion View residents, or 2.0%, live above that level. By land area, 5.1% of Mansion View is above 55 dBA.

Noise by Part of Mansion View
Average noise levels for Mansion View residents, grouped by direction from the center of Mansion View. Southern Mansion View carries the highest population-weighted average; Eastern Mansion View carries the lowest. Just 1% of residents in Eastern Mansion View live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in Southern Mansion View.
Eastern Mansion View
1% of people above 55 dBA
Northern Mansion View
3% of people above 55 dBA
Southern Mansion View
2% of people above 55 dBA
Southern Mansion View sounds about 24% louder than Eastern Mansion View to the human ear, a 3.1 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 Co Rd 229 do you need to be?
Co Rd 229 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 8% of Mansion View sits under tree canopy (lighter than most cities) and roughly 0% 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.
