This map shows modeled outdoor noise across Wood Streets 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 3,328 Wood Streets residents, or 50.2%, live above that level. By land area, 52.9% of Wood Streets is above 55 dBA.

Noise by Part of Wood Streets
Average noise levels for Wood Streets residents, grouped by direction from the center of Wood Streets. The highest population-weighted average is in eastern Wood Streets; the lowest is in northern Wood Streets, where just 22% of residents live in blocks above the EPA's 55 dBA threshold, a third of the share in the loudest section.
Eastern Wood Streets
82% of people above 55 dBA
Southeastern Wood Streets
67% of people above 55 dBA
Central Wood Streets
44% of people above 55 dBA
Western Wood Streets
35% of people above 55 dBA
Northern Wood Streets
22% of people above 55 dBA
To the human ear, noise in eastern Wood Streets sounds about 155% louder than in northern Wood Streets, a 13.5 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.
Rail Noise
Active freight rail runs through parts of Wood Streets. 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
Ontario International (ONT) sits northwest of Wood Streets. 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 Wood Streets, 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 Wood Streets
The bar chart below shows the share of Wood Streets residents in each noise band. About 52% of residents live below the EPA's 55 dBA threshold, and roughly 15% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Wood Streets Compares
Wood Streets sits at the quieter end of the spectrum. Below: how Wood Streets's average outdoor noise and share of residents above the EPA threshold compare with Downtown Riverside, Grand, Cooley Ranch, and La Sierra Hills.
Average noise level (dBA)
Wood Streets's 55.9 dBA pop-weighted average is at the quieter end of the spectrum. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Wood Streets because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 50.2% of Wood Streets 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, 52.9% of Wood Streets's footprint sits above 55 dBA, against a California average of 36.0% and a national average of 28.1%.
What This Means if You're Moving to Wood Streets
- 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 6% of Wood Streets is under tree cover (lighter than most 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. Ontario International'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.
