Osprey, FL Coastal Erosion Rate
What USGS measures 1.5 miles south of Osprey, FL
Nothing alarming measured 1.5 miles south of Osprey, FL: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
The grain of this number
Osprey, FL is the nearest named place, 1.5 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 27.17, -82.48. Survey years: 2001, method LRR, from USGS's Gulf of Mexico shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
What backs this reading up
35 transects feed this segment's number; 26% of them individually measured retreat. Uncertainty on this specific number: 0.25 ft/yr either side. The unadjusted figure here, 0.02 ft/yr, would place it 789 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2004-1089. For scale: North Wildwood, NJ, 929 miles away, ranks 1193 of 1211 nationally for growth, 4.21 ft/yr. Laurel, FL, 1.9 miles off, is the adjacent measured stretch, itself no significant trend.
