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 761 West Cloverdale residents, or 24.3%, live above that level. By land area, 28.7% of West Cloverdale is above 55 dBA.
Average noise levels for West Cloverdale residents, grouped by direction from the center of West Cloverdale. Western West Cloverdale carries the highest population-weighted average; Eastern West Cloverdale carries the lowest. Just 20% of residents in Eastern West Cloverdale live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Western West Cloverdale.

QuietLoud
Western West Cloverdale sounds about 27% louder than Eastern West Cloverdale to the human ear, a 3.5 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 do you need to be?
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 11% of West Cloverdale sits under tree canopy (about average for neighborhoods) and roughly 48% 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
Boise Air Trml/Gowen Field (BOI) sits southeast of West Cloverdale. The U.S. Department of Transportation models aviation noise around this airport from federal traffic data, 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 65 dBA on the map's Overall layer. Blocks on the opposite side of West Cloverdale, 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 West Cloverdale
The bar chart below shows the share of West Cloverdale residents in each noise band. About 87% 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 West Cloverdale Compares
West Cloverdale sits at the quieter end of the spectrum. Below: how West Cloverdale's average outdoor noise and share of residents above the EPA threshold compare with Downtown, Sunset, Highlands, and Hillcrest.
Average noise level (dBA)
West Cloverdale's 52.3 dBA pop-weighted average is at the quieter end of the spectrum. Idaho as a whole averages 50.6 dBA and the U.S. averages 52.0 dBA. Both are lower than West Cloverdale because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 24.3% of West Cloverdale 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, 28.7% of West Cloverdale's footprint sits above 55 dBA, against a Idaho average of 17.7% and a national average of 28.1%.
What This Means if You're Moving to West Cloverdale
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 11% of West Cloverdale is under tree cover (about average for neighborhoods), 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. Boise Air Trml/Gowen Field'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.
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.
