This map shows modeled outdoor noise across Spring Lake Park 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 1,492 Spring Lake Park residents, or 22.4%, live above that level. By land area, 23.9% of Spring Lake Park is above 55 dBA.

Noise by Part of Spring Lake Park
Average noise levels for Spring Lake Park residents, grouped by direction from the center of Spring Lake Park. Eastern Spring Lake Park carries the highest population-weighted average; Central Spring Lake Park carries the lowest. Just 9% of residents in Central Spring Lake Park live in blocks above the EPA's 55 dBA threshold, a third of the share in Eastern Spring Lake Park.
Central Spring Lake Park
9% of people above 55 dBA
Eastern Spring Lake Park
36% of people above 55 dBA
Northern Spring Lake Park
17% of people above 55 dBA
Southern Spring Lake Park
25% of people above 55 dBA
Western Spring Lake Park
15% of people above 55 dBA
Eastern Spring Lake Park sounds about 27% louder than Central Spring Lake Park to the human ear, a 3.4 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 Spring Lake Park 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 Coon Rapids Blvd NW do you need to be?
Coon Rapids Blvd NW 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 16% of Spring Lake Park sits under tree canopy (lighter than most cities) and roughly 37% 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.
Airport Noise
Minneapolis-St Paul International/Wold-Chamberlain (MSP) sits south of Spring Lake Park. 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 75 dBA on the map's Overall layer. Blocks on the opposite side of Spring Lake Park, particularly to the north, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Spring Lake Park
The bar chart below shows the share of Spring Lake Park residents in each noise band. About 76% of residents live below the EPA's 55 dBA threshold, and roughly 2% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Spring Lake Park Compares
Spring Lake Park sits at the quieter end of the spectrum. Below: how Spring Lake Park's average outdoor noise and share of residents above the EPA threshold compare with North Oaks, Dayton, Circle Pines, and St. Anthony.
Average noise level (dBA)
Spring Lake Park's 52.8 dBA pop-weighted average is at the quieter end of the spectrum. Minnesota as a whole averages 53.6 dBA and the U.S. averages 52.0 dBA. Both are lower than Spring Lake Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 22.4% of Spring Lake Park residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's in the middle of its peer group. Measured by land area instead, 23.9% of Spring Lake Park'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 Spring Lake Park
- 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 Coon Rapids Blvd NW 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 16% of Spring Lake Park is under tree cover (lighter than most cities), 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 south. Neighborhoods to the north 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.
