Tiger Point, FL Coastal Erosion Rate

Shoreline change 1 miles east of Tiger Point, FL

No significant trend

The coast 1 miles east of Tiger Point, 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 Tiger Point, FL into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 30.38°N, 87.04°W. USGS's Gulf of Mexico assessment last surveyed this stretch through 2001, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.

Where this fits nationally

Averaging 42 separate transects produced this segment's rate, with 100% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.51 ft/yr either side. Taken at face value, this segment's raw -0.18 ft/yr reading would land it 520 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: Gearhart, OR, 2248 miles away, ranks 1167 of 1211 nationally for growth, 2.24 ft/yr. 1.5 miles away, Tiger Point, FL is the nearest other measured stretch: also no significant trend.

Not this whole stretch, just Tiger Point itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
