This map shows modeled outdoor noise across Canyon 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 1,470 Canyon Park residents, or 40.6%, live above that level. By land area, 46.5% of Canyon Park is above 55 dBA.

Noise by Part of Canyon Park
Average noise levels for Canyon Park residents, grouped by direction from the center of Canyon Park. The highest population-weighted average is in central Canyon Park; the lowest is in northeastern Canyon Park, where just 19% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in central Canyon Park sounds about 177% louder than in northeastern Canyon Park, a 14.7 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.
How far back from I-405 do you need to be?
I-405 produces an estimated 77 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.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 53% of Canyon Park sits under tree canopy (much heavier than most neighborhoods) and roughly 28% 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
Seattle-Tacoma International (SEA) sits south of Canyon 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 45 dBA on the map's Overall layer. Blocks on the opposite side of Canyon 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 Canyon Park
The bar chart below shows the share of Canyon Park residents in each noise band. About 21% of residents live below the EPA's 55 dBA threshold, and roughly 11% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Canyon Park Compares
Canyon Park sits at the louder end of the spectrum. Below: how Canyon Park's average outdoor noise and share of residents above the EPA threshold compare with Queensboro-Brentwood-Crystal Spgs, Canyon Creek-39th SE, Westhill, and Wedge.
Average noise level (dBA)
Canyon Park's 57.1 dBA pop-weighted average is at the louder end of the spectrum. Washington as a whole averages 51.3 dBA and the U.S. averages 52.0 dBA. Both are lower than Canyon Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 40.6% of Canyon 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, 46.5% of Canyon Park'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 Canyon 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 I-405 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 53% of Canyon Park is under tree cover (much heavier than most neighborhoods), and the dominant land cover is low-density developed open space. 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. Seattle-Tacoma International's approach paths concentrate aviation noise to the south. Neighborhoods to the north of downtown show no measurable contribution from the airport.
