Seadrift, TX Coastal Erosion Rate
What USGS measures 12.8 miles south of Seadrift, TX
12.8 miles south of Seadrift, TX: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
What "Seadrift" 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 Seadrift, TX. Centered near 28.24°N, 96.65°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.
Where this fits nationally
97 transects feed this segment's number; 0% of them individually measured retreat. USGS's confidence interval here is ±1.25 ft/yr. Taken at face value, this segment's raw 0.48 ft/yr reading would land it 1020 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Rank 1024 nationally for growth belongs to Camp Pendleton South, CA, 1282 miles from this stretch, measured at 0.49 ft/yr. 1.9 miles up the coast, Seadrift, TX shows the same lack of a significant trend.
