Sargent, TX Coastal Erosion Rate
Shoreline change 4.9 miles east of Sargent, TX
4.4 feet a year: that is the measured retreat rate USGS's transects show for the coast 4.9 miles east of Sargent, TX, averaged across the full historical record surveyed here. At that rate, the shoreline has lost roughly 44 feet over the last decade.
The grain of this number
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Sargent, TX into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 28.82°N, 95.56°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 4.4 ft/yr holds for the next 25 years, the coast 4.9 miles east of Sargent, TX would retreat roughly 110 more feet, a projection, not a certainty: erosion rates shift with storms, sediment supply and any armoring built in the meantime.
Where this fits nationally
This reading comes from 52 individual transects averaged together, 100% of which measured erosion rather than growth. Uncertainty on this specific number: 1.63 ft/yr either side. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 63. Source: USGS Open-File Report 2004-1089. Corpus Christi, TX sits at national rank 236 for erosion (0.74 ft/yr), one reference point among the 1211 scored segments, 119 miles from here. 1.8 miles up the coast, Sargent, TX shows 4.11 ft/yr of eroding.
