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 59 56089 residents, or 43.9%, live above that level. By land area, 31.8% of 56089 is above 55 dBA.

Noise by Part of 56089

Average noise levels for 56089 residents, grouped by direction from the center of 56089. Central 56089 carries the highest population-weighted average; Western 56089 carries the lowest. Just 0% of residents in Western 56089 live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Central 56089.

QuietLoud

Central 56089 sounds about 216% louder than Western 56089 to the human ear, a 16.6 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 135TH St do you need to be?

135TH St 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 25% of 56089 sits under tree canopy (about average for zip codes) and roughly 14% 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.

How Noise Is Distributed Across 56089

The bar chart below shows the share of 56089 residents in each noise band. About 70% of residents live below the EPA's 55 dBA threshold, and roughly 0% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How 56089 Compares

56089 sits at the louder end of the spectrum. Below: how 56089's average outdoor noise and share of residents above the EPA threshold compare with 56020, 56032, 55977, and 56043.

Average noise level (dBA)

56089's 53.0 dBA pop-weighted average is at the louder end of the spectrum. Minnesota as a whole averages 53.6 dBA and the U.S. averages 52.0 dBA. Both are lower than 56089 because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 43.9% of 56089 residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 31.8% of 56089's footprint sits above 55 dBA, against a Minnesota average of 31.0% and a national average of 28.1%.

What This Means if You're Moving to 56089

  • Distance from highways matters more than the neighborhood name. Two homes in the same zip code can differ by 20 dBA if one sits 100 meters from 135TH St and the other 500 meters away. The model captures this at 100-meter resolution, so noise exposure changes block by block.
  • Tree canopy can help reduce modeled noise exposure. Roughly 25% of 56089 is under tree cover (about average for zip codes), and the dominant land cover is low-intensity developed land. Both are measured from federal USDA Forest Service and USGS satellite imagery at 30-meter resolution. Streets with 60% or higher canopy show 3 to 5 dBA lower noise than comparable streets with bare ground or pavement, which is why the per-place decay rate above already accounts for it.

Sources & Methodology

The BestNeighborhood noise model is calibrated against nearly one million federal ground-truth measurements across four states. Road noise is computed from segment-level federal traffic data and propagated outward using physics-based acoustic decay, with attenuation rates that depend on the surrounding land cover.

Federal datasets used:

FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level

All inputs are published federal datasets. Block-level noise is computed by combining road, rail, and aviation sound sources in the energy domain, the same physics used in professional environmental noise assessments. Read the full methodology.
