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 2,031 Cascade View residents, or 33.7%, live above that level. By land area, 33.1% of Cascade View is above 55 dBA.
Average noise levels for Cascade View residents, grouped by direction from the center of Cascade View. Eastern Cascade View carries the highest population-weighted average; Central Cascade View carries the lowest. Just 31% of residents in Central Cascade View live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Eastern Cascade View.

QuietLoud
Eastern Cascade View sounds about 80% louder than Central Cascade View to the human ear, a 8.5 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 71 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 19% of Cascade View sits under tree canopy (about average for neighborhoods) and roughly 58% 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 Cascade View
The bar chart below shows the share of Cascade View residents in each noise band. About 38% of residents live below the EPA's 55 dBA threshold, and roughly 27% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Cascade View Compares
Cascade View sits the highest among the peer group. Below: how Cascade View's average outdoor noise and share of residents above the EPA threshold compare with Delta, Evergreen, View Ridge-Madison, and Boulevard Bluffs.
Average noise level (dBA)
Cascade View's 55.7 dBA pop-weighted average is the highest among the peer group. Washington as a whole averages 51.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Cascade View because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 33.7% of Cascade View 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, 33.1% of Cascade View's footprint sits above 55 dBA, against a Washington average of 27.7% and a national average of 28.1%.
What This Means if You're Moving to Cascade View
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 19% of Cascade View is under tree cover (about average for neighborhoods), and the dominant land cover is medium-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.
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.
