Eastpoint, FL Coastal Erosion Rate
What USGS measures 6.7 miles east of Eastpoint, FL
USGS's shoreline-change data puts this stretch, 6.7 miles east of Eastpoint, FL, at 0.97 feet of erosion a year on average, a long-term rate for this specific ~3.5-mile section, not one storm's damage. At that rate, the shoreline has lost roughly 9.7 feet over the last decade.
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 Eastpoint, FL, rather than showing one arbitrary line. Segment center: 29.75, -84.75. 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.
What 0.97 ft/yr means over time
Run 6.7 miles east of Eastpoint, FL's 0.97 ft/yr rate forward 25 years and it implies about 24 feet of further retreat, assuming nothing changes, which is exactly the assumption a seawall or nourishment project exists to break.
Where this fits nationally
123 transects feed this segment's number; 100% of them individually measured retreat. The published margin on this reading runs ±0.38 ft/yr. This segment ranks 199 of 1211 measured US coastal segments, ordered from fastest erosion to fastest growth. Source: USGS Open-File Report 2004-1089. For scale: Edgartown, MA, 1125 miles away, ranks 140 of 1211 nationally for erosion, 1.85 ft/yr, 1.9x this stretch's rate. Eastpoint, FL, 2.1 miles off, is the adjacent measured stretch, itself no significant trend.
Not this whole stretch, just Eastpoint itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
