This map shows modeled outdoor noise across Del Monte Forest 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 646 Del Monte Forest residents, or 14.0%, live above that level. By land area, 8.7% of Del Monte Forest is above 55 dBA.

Noise by Part of Del Monte Forest
Average noise levels for Del Monte Forest residents, grouped by direction from the center of Del Monte Forest. The highest population-weighted average is in southeastern Del Monte Forest; the lowest is in western Del Monte Forest, where just 0% of residents live in blocks above the EPA's 55 dBA threshold, a fifth of the share in the loudest section.
Southeastern Del Monte Forest
23% of people above 55 dBA
Northeastern Del Monte Forest
12% of people above 55 dBA
Southern Del Monte Forest
5% of people above 55 dBA
Northwestern Del Monte Forest
2% of people above 55 dBA
Western Del Monte Forest
0% of people above 55 dBA
To the human ear, noise in southeastern Del Monte Forest sounds about 376% louder than in western Del Monte Forest, a 22.5 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.
How Noise Is Distributed Across Del Monte Forest
The bar chart below shows the share of Del Monte Forest residents in each noise band. About 96% 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 Del Monte Forest Compares
Del Monte Forest sits at the quieter end of the spectrum. Below: how Del Monte Forest's average outdoor noise and share of residents above the EPA threshold compare with Carmel Valley, Carmel-By-The-Sea, Castroville, and Moss Landing.
Average noise level (dBA)
Del Monte Forest's 52.0 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 Del Monte Forest because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 14.0% of Del Monte Forest 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, 8.7% of Del Monte Forest'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 Del Monte Forest
- 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 47% of Del Monte Forest is under tree cover (heavier than most cities), and the dominant land cover is evergreen forest. 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.
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.
