Sargent, TX Coastal Erosion Rate
What USGS measures 2.3 miles southwest of Sargent, TX
4.77 feet a year: that is the measured retreat rate USGS's transects show for the coast 2.3 miles southwest of Sargent, TX, averaged across the full historical record surveyed here. At that rate, the shoreline has lost roughly 47.7 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 28.77°N, 95.66°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 4.77 ft/yr holds for the next 25 years, the coast 2.3 miles southwest of Sargent, TX would retreat roughly 119 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 57 individual transects averaged together, 100% of which measured erosion rather than growth. The published margin on this reading runs ±2.67 ft/yr. Among the 1211 US coastal segments with a measurable trend, this one ranks 54 for erosion, 1 being the fastest-retreating coast in the dataset. Source: USGS Open-File Report 2004-1089.
