This map shows modeled outdoor noise across Maple 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 27 Maple Grove residents, or 34.0%, live above that level. By land area, 29.1% of Maple Grove is above 55 dBA.

Noise by Part of Maple Grove
Average noise levels for Maple Grove residents, grouped by direction from the center of Maple Grove. Northern Maple Grove carries the highest population-weighted average; Southern Maple Grove carries the lowest. Just 2% of residents in Southern Maple Grove live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Northern Maple Grove.
Eastern Maple Grove
30% of people above 55 dBA
Northern Maple Grove
79% of people above 55 dBA
Southern Maple Grove
2% of people above 55 dBA
Western Maple Grove
18% of people above 55 dBA
Northern Maple Grove sounds about 150% louder than Southern Maple Grove to the human ear, a 13.2 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 Glasgowln do you need to be?
Glasgowln produces an estimated 59 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 0% of Maple Grove sits under tree canopy (much lighter than most cities) and roughly 4% 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.
