Sargent, TX Coastal Erosion Rate
Shoreline change 6.7 miles east of Sargent, TX
The coast 6.7 miles east of Sargent, TX has been retreating at a measured 4.11 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 41.1 feet over the last decade.
What "Sargent" means on this page
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 28.83°N, 95.54°W. 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.
25 years at this rate
If 4.11 ft/yr holds for the next 25 years, the coast 6.7 miles east of Sargent, TX would retreat roughly 103 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
This reading comes from 62 individual transects averaged together, 100% of which measured erosion rather than growth. Uncertainty on this specific number: 1.77 ft/yr either side. Among the 1211 US coastal segments with a measurable trend, this one ranks 71 for erosion, 1 being the fastest-retreating coast in the dataset. Source: USGS Open-File Report 2004-1089. Rank 372 nationally for erosion belongs to Half Moon Bay, CA, 1658 miles from this stretch, measured at 0.36 ft/yr, a small fraction of this stretch's own rate. 1.8 miles up the coast, Sargent, TX shows 4.4 ft/yr of eroding.
