Nokomis, FL Coastal Erosion Rate
Is the coast eroding 1.9 miles southwest of Nokomis, FL?
The coast 1.9 miles southwest of Nokomis, FL shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.
What this reading actually covers
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Nokomis, FL into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 27.10°N, 82.45°W. 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 120 individual transects averaged together, 70% of which measured erosion rather than growth. Uncertainty on this specific number: 0.98 ft/yr either side. Taken at face value, this segment's raw -0.27 ft/yr reading would land it 419 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Gearhart, OR sits at national rank 1187 for growth (3.64 ft/yr), one reference point among the 1211 scored segments, 2609 miles from here. 2.7 miles up the coast, Venice Gardens, FL shows the same lack of a significant trend.
Not this whole stretch, just Nokomis itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
