This map shows modeled outdoor noise across South Boulevard Park Row 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 7,595 South Boulevard Park Row residents, or 56.7%, live above that level. By land area, 67.0% of South Boulevard Park Row is above 55 dBA.

Noise by Part of South Boulevard Park Row
Average noise levels for South Boulevard Park Row residents, grouped by direction from the center of South Boulevard Park Row. Western South Boulevard Park Row carries the highest population-weighted average; Central South Boulevard Park Row carries the lowest. Just 0% of residents in Central South Boulevard Park Row live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Western South Boulevard Park Row.
Central South Boulevard Park Row
0% of people above 55 dBA
Eastern South Boulevard Park Row
33% of people above 55 dBA
Northern South Boulevard Park Row
72% of people above 55 dBA
Southern South Boulevard Park Row
26% of people above 55 dBA
Western South Boulevard Park Row
81% of people above 55 dBA
Western South Boulevard Park Row sounds about 72% louder than Central South Boulevard Park Row to the human ear, a 7.8 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.
Loudest Road Corridors
The model evaluates every road in South Boulevard Park Row using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.
How far back from US Hwy 67 do you need to be?
US Hwy 67 produces an estimated 79 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 office.
Calculated from the model's calibrated attenuation formula. About 17% of South Boulevard Park Row sits under tree canopy (about average for neighborhoods) and roughly 45% 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 South Boulevard Park Row. 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
Dallas Love Field (DAL) sits northwest of South Boulevard Park Row. 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 50 dBA on the map's Overall layer. Blocks on the opposite side of South Boulevard Park Row, particularly to the southeast, show no measurable aviation contribution. Use the Aviation toggle on the map above to isolate the airport's footprint.
How Noise Is Distributed Across South Boulevard Park Row
The bar chart below shows the share of South Boulevard Park Row residents in each noise band. About 43% of residents live below the EPA's 55 dBA threshold, and roughly 24% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How South Boulevard Park Row Compares
South Boulevard Park Row sits at the quieter end of the spectrum. Below: how South Boulevard Park Row's average outdoor noise and share of residents above the EPA threshold compare with Urbandale-Parkdale, Love Field Area, Southwest Carrollton, and Near East.
Average noise level (dBA)
South Boulevard Park Row's 56.4 dBA pop-weighted average is at the quieter end of the spectrum. Texas as a whole averages 50.8 dBA and the U.S. averages 52.0 dBA. Both are lower than South Boulevard Park Row because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 56.7% of South Boulevard Park Row 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, 67.0% of South Boulevard Park Row's footprint sits above 55 dBA, against a Texas average of 22.8% and a national average of 28.1%.
What This Means if You're Moving to South Boulevard Park Row
- 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 US Hwy 67 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 17% of South Boulevard Park Row 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. Dallas Love Field's approach paths concentrate aviation noise to the northwest. Neighborhoods to the southeast 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.
