Sarasota, FL Coastal Erosion Rate
Shoreline change 2.1 miles southwest of Sarasota, FL
2.1 miles southwest of Sarasota, FL: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
What "Sarasota" means on this page
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Sarasota, FL. Centered near 27.33°N, 82.57°W. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
How solid is this number
4 transects feed this segment's number; 0% of them individually measured retreat. USGS's confidence interval here is ±1.85 ft/yr. Taken at face value, this segment's raw 0.92 ft/yr reading would land it 1094 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. For scale: Inverness, CA, 2442 miles away, ranks 959 of 1211 nationally for growth, 0.27 ft/yr. 2.3 miles away, Siesta Key, FL is the nearest other measured stretch: also no significant trend.
