North Redington Beach, FL Coastal Erosion Rate
Shoreline change 0.6 miles north of North Redington Beach, FL
0.6 miles north of North Redington Beach, FL, the coast is advancing, not retreating, at a measured 0.84 feet a year, sediment accumulating faster than any erosion USGS recorded here. At that rate, the shoreline has gained roughly 8.4 feet over the last decade.
The grain of this number
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest North Redington Beach, FL. Centered near 27.83°N, 82.82°W. 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.
25 years at this rate
Holding the 0.84 ft/yr accretion rate 0.6 miles north of North Redington Beach, FL for 25 years would add roughly 21 feet of shoreline, again assuming nothing about the local sediment supply changes.
What backs this reading up
29 transects feed this segment's number; 0% of them individually measured retreat. The published margin on this reading runs ±0.83 ft/yr. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 1084. Source: USGS Open-File Report 2004-1089. For scale: San Buenaventura (Ventura), CA, 2191 miles away, ranks 1122 of 1211 nationally for growth, 1.19 ft/yr, 1.4x this stretch's rate. 1.9 miles away, Indian Shores, FL is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just North Redington Beach itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
