Siesta Key, FL Coastal Erosion Rate
Shoreline change 1.5 miles northwest of Siesta Key, FL
Nothing alarming measured 1.5 miles northwest of Siesta Key, 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.
What "Siesta Key" means on this page
Siesta Key, 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: 27.30, -82.56. 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.
Where this fits nationally
This reading comes from 122 individual transects averaged together, 38% of which measured erosion rather than growth. Uncertainty on this specific number: 1.83 ft/yr either side. The unadjusted figure here, 0.36 ft/yr, would place it 986 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. Westport, WA sits at national rank 1128 for growth (1.25 ft/yr), one reference point among the 1211 scored segments, 2618 miles from here. 2.3 miles away, Sarasota, FL is the nearest other measured stretch: also no significant trend.
