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 19,406 Valley Oak residents, or 44.8%, live above that level. By land area, 46.3% of Valley Oak is above 55 dBA.
Average noise levels for Valley Oak residents, grouped by direction from the center of Valley Oak. Southern Valley Oak carries the highest population-weighted average; Western Valley Oak carries the lowest. Just 39% of residents in Western Valley Oak live in blocks above the EPA's 55 dBA threshold, roughly the same as the share in Southern Valley Oak.

QuietLoud
Southern Valley Oak sounds about 21% louder than Western Valley Oak to the human ear, a 2.7 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 State Rte 99 do you need to be?
State Rte 99 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 soft rainfall.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 3% of Valley Oak sits under tree canopy (much lighter than most neighborhoods) and roughly 60% 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 Valley Oak. 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.
How Noise Is Distributed Across Valley Oak
The bar chart below shows the share of Valley Oak residents in each noise band. About 46% of residents live below the EPA's 55 dBA threshold, and roughly 19% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How Valley Oak Compares
Valley Oak sits the lowest among the peer group. Below: how Valley Oak's average outdoor noise and share of residents above the EPA threshold compare with Pacific, Park, Seaport, and Bear Creek.
Average noise level (dBA)
Valley Oak's 55.6 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 Valley Oak because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 44.8% of Valley Oak 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, 46.3% of Valley Oak'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 Valley Oak
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 State Rte 99 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 3% of Valley Oak is under tree cover (much 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.
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.
