This map shows modeled outdoor noise across 55419 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 24,104 55419 residents, or 98.3%, live above that level. By land area, 97.7% of 55419 is above 55 dBA.

Noise by Part of 55419
Average noise levels for 55419 residents, grouped by direction from the center of 55419. Eastern 55419 carries the highest population-weighted average; Western 55419 carries the lowest. Just 96% of residents in Western 55419 live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Eastern 55419.
Central 55419
100% of people above 55 dBA
Eastern 55419
100% of people above 55 dBA
Northern 55419

Southern 55419
97% of people above 55 dBA
Western 55419
96% of people above 55 dBA
Eastern 55419 sounds about 23% louder than Western 55419 to the human ear, a 3.0 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.
Loudest Road Corridors
The model evaluates every road in 55419 using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.
How far back from 35W do you need to be?
35W produces an estimated 80 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 quiet suburban street at night.
Calculated from the model's calibrated attenuation formula. About 18% of 55419 sits under tree canopy (about average for zip codes) and roughly 46% 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.
Rail Noise
Active freight rail runs through parts of 55419. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
Airport Noise
Minneapolis-St Paul International/Wold-Chamberlain (MSP) sits southeast of 55419. The U.S. Department of Transportation measures aviation noise around this airport directly, and the model uses those federal measurements rather than synthetic predictions.
Blocks under the approach and departure paths carry combined road-plus-aviation noise, with some exceeding 60 dBA on the map's Overall layer. Blocks on the opposite side of 55419, particularly to the northwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across 55419
The bar chart below shows the share of 55419 residents in each noise band. About 0% of residents live below the EPA's 55 dBA threshold, and roughly 69% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 55419 Compares
55419 sits at the louder end of the spectrum. Below: how 55419's average outdoor noise and share of residents above the EPA threshold compare with 55426, 55417, 55408, and 55404.
Average noise level (dBA)
55419's 61.2 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 55419 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 98.3% of 55419 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, 97.7% of 55419'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 55419
- 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 35W 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 18% of 55419 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.
- Airport noise is directional. Minneapolis-St Paul International/Wold-Chamberlain's approach paths concentrate aviation noise to the southeast. Neighborhoods to the northwest of downtown show no measurable contribution from the airport.
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.
