This map shows modeled outdoor noise across Cypress-Riverside 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 1,686 Cypress-Riverside residents, or 33.8%, live above that level. By land area, 39.0% of Cypress-Riverside is above 55 dBA.

Southern Cypress-Riverside carries the highest population-weighted average; Northern Cypress-Riverside carries the lowest. Just 15% of residents in Northern Cypress-Riverside live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern Cypress-Riverside.

Southern Cypress-Riverside sounds about 93% louder than Northern Cypress-Riverside to the human ear, a 9.5 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 far back from do you need to be?
produces an estimated 70 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 2% of Cypress-Riverside sits under tree canopy (much lighter than most neighborhoods) and roughly 40% 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.
