This map shows modeled outdoor noise across Rocky Point 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 1,962 Rocky Point residents, or 15.8%, live above that level. By land area, 18.8% of Rocky Point is above 55 dBA.

Noise by Part of Rocky Point
Average noise levels for Rocky Point residents, grouped by direction from the center of Rocky Point. Central Rocky Point carries the highest population-weighted average; Southern Rocky Point carries the lowest. Just 7% of residents in Southern Rocky Point live in blocks above the EPA's 55 dBA threshold, a third of the share in Central Rocky Point.
Central Rocky Point
31% of people above 55 dBA
Eastern Rocky Point
14% of people above 55 dBA
Northern Rocky Point
16% of people above 55 dBA
Southern Rocky Point
7% of people above 55 dBA
Western Rocky Point
17% of people above 55 dBA
Central Rocky Point sounds about 88% louder than Southern Rocky Point to the human ear, a 9.1 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 Rocky Point Rd do you need to be?
Rocky Point Rd produces an estimated 59 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.
Calculated from the model's calibrated attenuation formula. About 58% of Rocky Point sits under tree canopy (heavier than most cities) and roughly 16% 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.
