This map shows modeled outdoor noise across 33850 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 1,579 33850 residents, or 20.4%, live above that level. By land area, 28.9% of 33850 is above 55 dBA.

Noise by Part of 33850
Average noise levels for 33850 residents, grouped by direction from the center of 33850. The highest population-weighted average is in northeastern 33850; the lowest is in southwestern 33850, where just 9% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.

Quiet office to normal conversation
To the human ear, noise in northeastern 33850 sounds about 60% louder than in southwestern 33850, a 6.8 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 S Lake Shore Way do you need to be?
S Lake Shore Way 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.

Soft rainfall
Calculated from the model's calibrated attenuation formula. About 12% of 33850 sits under tree canopy (lighter than most zip codes) and roughly 31% 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 33850. 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 33850
The bar chart below shows the share of 33850 residents in each noise band. About 76% of residents live below the EPA's 55 dBA threshold, and roughly 8% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How 33850 Compares
33850 sits the highest among the peer group. Below: how 33850's average outdoor noise and share of residents above the EPA threshold compare with 33859, 33868, 33838, and 33853.
Average noise level (dBA)
33850's 51.2 dBA pop-weighted average is the highest among the peer group. Florida as a whole averages 51.6 dBA and the U.S. averages 52.0 dBA. Both are lower than 33850 because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 20.4% of 33850 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, 28.9% of 33850's footprint sits above 55 dBA, against a Florida average of 31.8% and a national average of 28.1%.
What This Means if You're Moving to 33850
- 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 S Lake Shore Way 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 12% of 33850 is under tree cover (lighter than most zip codes), and the dominant land cover is low-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.
