Sargent, TX Coastal Erosion Rate
What USGS measures 2.5 miles east of Sargent, TX
The coast 2.5 miles east of Sargent, TX has been retreating at a measured 4.63 feet a year, USGS's own long-term rate for this stretch, built from historical shoreline positions rather than a single survey. At that rate, the shoreline has lost roughly 46.3 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 Sargent, TX. Centered near 28.80°N, 95.60°W. 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.
25 years at this rate
If 4.63 ft/yr holds for the next 25 years, the coast 2.5 miles east of Sargent, TX would retreat roughly 116 more feet, a projection, not a certainty: erosion rates shift with storms, sediment supply and any armoring built in the meantime.
What backs this reading up
114 transects feed this segment's number; 100% of them individually measured retreat. The published margin on this reading runs ±2.67 ft/yr.
