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 12 Orinda Village residents, or 6.9%, live above that level. By land area, 2.4% of Orinda Village is above 55 dBA.
Average noise levels for Orinda Village residents, grouped by direction from the center of Orinda Village. Southern Orinda Village carries the highest population-weighted average; Northern Orinda Village carries the lowest. Just 0% of residents in Northern Orinda Village live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Orinda Village.

QuietLoud
Southern Orinda Village sounds about 498% louder than Northern Orinda Village to the human ear, a 25.8 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.
How far back from do you need to be?
produces an estimated 82 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 31% of Orinda Village sits under tree canopy (about average for cities) and roughly 0% 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
San Francisco Bay Oakland International (OAK) sits south of Orinda Village. 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 Orinda Village, 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 Orinda Village
The bar chart below shows the share of Orinda Village residents in each noise band. About 99% of residents live below the EPA's 55 dBA threshold, and roughly 1% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Orinda Village Compares
Orinda Village sits the lowest among the peer group. Below: how Orinda Village's average outdoor noise and share of residents above the EPA threshold compare with Castle Hill, Greenbrae, Canyon, and Port Costa.
Average noise level (dBA)
Orinda Village's 42.8 dBA pop-weighted average is the lowest among the peer group. California as a whole averages 54.0 dBA and the U.S. averages 52.0 dBA. Both are lower than Orinda Village because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 6.9% of Orinda Village 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, 2.4% of Orinda Village'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 Orinda Village
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 31% of Orinda Village is under tree cover (about average for cities), and the dominant land cover is shrub / scrub. 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. San Francisco Bay Oakland International's approach paths concentrate aviation noise to the south. Neighborhoods to the north 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.
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.
