Woodlawn Beach, FL Coastal Erosion Rate
What USGS measures 0.4 miles southwest of Woodlawn Beach, FL
Nothing alarming measured 0.4 miles southwest of Woodlawn Beach, 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 "Woodlawn Beach" means on this page
Woodlawn Beach, FL is the nearest named place, 0.4 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: 30.38, -87.00. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
How solid is this number
This reading comes from 98 individual transects averaged together, 84% of which measured erosion rather than growth. The published margin on this reading runs ±0.43 ft/yr. The unadjusted figure here, -0.07 ft/yr, would place it 683 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. Rank 1122 nationally for growth belongs to San Buenaventura (Ventura), CA, 1895 miles from this stretch, measured at 1.19 ft/yr. Tiger Point, FL, 2.2 miles off, is the adjacent measured stretch, itself no significant trend.
