This map shows modeled outdoor noise across Utah 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 1,061 Utah Park residents, or 21.3%, live above that level. By land area, 21.9% of Utah Park is above 55 dBA.

Noise by Part of Utah Park
Average noise levels for Utah Park residents, grouped by direction from the center of Utah Park. The highest population-weighted average is in southern Utah Park; the lowest is in northern Utah Park, where just 24% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in southern Utah Park sounds about 55% louder than in northern Utah Park, a 6.3 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-225 do you need to be?
I-225 produces an estimated 78 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 7% of Utah Park sits under tree canopy (lighter than most neighborhoods) and roughly 50% 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.

Rail Noise
Active freight rail runs through parts of Utah Park. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
Airport Noise
Denver International (DEN) sits northeast of Utah 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 Utah Park, 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 Utah Park
The bar chart below shows the share of Utah Park residents in each noise band. About 80% of residents live below the EPA's 55 dBA threshold, and roughly 5% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Utah Park Compares
Utah Park sits at the quieter end of the spectrum. Below: how Utah Park's average outdoor noise and share of residents above the EPA threshold compare with Highline Villages, City Center, Horseshoe Park, and East Ridge-Ptarmigan Park.
Average noise level (dBA)
Utah Park's 51.4 dBA pop-weighted average is at the quieter end of the spectrum. Colorado as a whole averages 51.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Utah Park because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 21.3% of Utah Park residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's fewer than any of its peer group. Measured by land area instead, 21.9% of Utah Park's footprint sits above 55 dBA, against a Colorado average of 25.4% and a national average of 28.1%.
What This Means if You're Moving to Utah 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-225 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 7% of Utah Park is under tree cover (lighter than most 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.
- Airport noise is directional. Denver International's approach paths concentrate aviation noise to the northeast. Neighborhoods to the southwest of downtown show no measurable contribution from the airport.
