This map shows modeled outdoor noise across Country Walk 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 5,524 Country Walk residents, or 39.1%, live above that level. By land area, 47.4% of Country Walk is above 55 dBA.

Noise by Part of Country Walk
Average noise levels for Country Walk residents, grouped by direction from the center of Country Walk. The highest population-weighted average is in northern Country Walk; the lowest is in northwestern Country Walk, where just 30% of residents live in blocks above the EPA's 55 dBA threshold, about two-thirds of the share in the loudest section.
Northern Country Walk
50% of people above 55 dBA
Southwestern Country Walk
57% of people above 55 dBA
Northeastern Country Walk
39% of people above 55 dBA
Central Country Walk
33% of people above 55 dBA
Northwestern Country Walk
30% of people above 55 dBA
To the human ear, noise in northern Country Walk sounds about 21% louder than in northwestern Country Walk, a 2.7 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.
Airport Noise
Miami International (MIA) sits northeast of Country Walk. 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 85 dBA on the map's Overall layer. Blocks on the opposite side of Country Walk, particularly to the southwest, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across Country Walk
The bar chart below shows the share of Country Walk residents in each noise band. About 58% 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 Country Walk Compares
Country Walk sits the lowest among the peer group. Below: how Country Walk's average outdoor noise and share of residents above the EPA threshold compare with Three Lakes, Palmetto Estates, Goulds, and The Crossings.
Average noise level (dBA)
Country Walk's 54.0 dBA pop-weighted average is the lowest among the peer group. Florida as a whole averages 51.6 dBA and the U.S. averages 52.0 dBA. Both are lower than Country Walk because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 39.1% of Country Walk 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, 47.4% of Country Walk's footprint sits above 55 dBA, against a Florida average of 31.8% and a national average of 28.1%.
What This Means if You're Moving to Country Walk
- 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 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 10% of Country Walk 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. Miami International's approach paths concentrate aviation noise to the northeast. Neighborhoods to the southwest 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.
