Laguna Beach, FL Coastal Erosion Rate
Shoreline change 1.9 miles north of Laguna Beach, FL
Good news, and an honest one: USGS's data can't distinguish this stretch, 1.9 miles north of Laguna Beach, FL, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
What this reading actually covers
USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Laguna Beach, FL, rather than showing one arbitrary line. Segment center: 30.28, -85.96. 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.
What backs this reading up
72 transects feed this segment's number; 74% of them individually measured retreat. The published margin on this reading runs ±0.6 ft/yr. The unadjusted figure here, -0.04 ft/yr, would place it 720 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. For scale: Anchor Bay, CA, 2201 miles away, ranks 1039 of 1211 nationally for growth, 0.58 ft/yr. 1.7 miles away, Laguna Beach, FL is the nearest other measured stretch: also no significant trend.
