Tierra Verde, FL Coastal Erosion Rate
Shoreline change 1.6 miles south of Tierra Verde, FL
The coast 1.6 miles south of Tierra Verde, 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.
The grain of this number
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Tierra Verde, FL into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 27.64°N, 82.73°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.
How solid is this number
Averaging 60 separate transects produced this segment's rate, with 40% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±6.42 ft/yr. Taken at face value, this segment's raw 0.59 ft/yr reading would land it 1041 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Newport, OR sits at national rank 1121 for growth (1.16 ft/yr), one reference point among the 1211 scored segments, 2552 miles from here. Tierra Verde, FL, 3 miles off, is the adjacent measured stretch, itself no significant trend.
Not this whole stretch, just Tierra Verde itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
