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 878 Crescent City residents, or 18.6%, live above that level. By land area, 21.9% of Crescent City is above 55 dBA.

Noise by Part of Crescent City
Average noise levels for Crescent City residents, grouped by direction from the center of Crescent City. The highest population-weighted average is in southeastern Crescent City; the lowest is in northwestern Crescent City, where just 3% of residents live in blocks above the EPA's 55 dBA threshold, three-quarters of the share in the loudest section.

To the human ear, noise in southeastern Crescent City sounds about 14% louder than in northwestern Crescent City, a 1.9 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 Summit St do you need to be?
Summit St produces an estimated 63 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 39% of Crescent City sits under tree canopy (about average for cities) and roughly 12% 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 Crescent City. 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 Crescent City
The bar chart below shows the share of Crescent City residents in each noise band. About 89% 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 Crescent City Compares
Crescent City sits at the louder end of the spectrum. Below: how Crescent City's average outdoor noise and share of residents above the EPA threshold compare with Satsuma, East Palatka, Fort Mc Coy, and Pomona Park.
Average noise level (dBA)
Crescent City's 49.9 dBA pop-weighted average is at the louder end of the spectrum. Florida as a whole averages 51.6 dBA and the U.S. averages 52.0 dBA. Both are lower than Crescent City because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 18.6% of Crescent City residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 21.9% of Crescent City'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 Crescent City
- 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 Summit St 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 39% of Crescent City is under tree cover (about average for cities), and the dominant land cover is low-density developed open space. 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.
