Lake Lorraine, FL Coastal Erosion Rate
Shoreline change 2 miles southeast of Lake Lorraine, FL
The coast 2 miles southeast of Lake Lorraine, 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 Lake Lorraine, FL into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 30.42°N, 86.55°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
This reading comes from 90 individual transects averaged together, 48% of which measured erosion rather than growth. USGS's confidence interval here is ±0.67 ft/yr. Taken at face value, this segment's raw 0.1 ft/yr reading would land it 850 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Rank 1136 nationally for growth belongs to Seaside, OR, 2269 miles from this stretch, measured at 1.36 ft/yr. 2.9 miles away, Destin, FL is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Lake Lorraine itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
