Seadrift, TX Coastal Erosion Rate
What USGS measures 13.5 miles south of Seadrift, TX
The coast 13.5 miles south of Seadrift, TX shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.
What this reading actually covers
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Seadrift, TX into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 28.22°N, 96.67°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
20 transects feed this segment's number; 0% of them individually measured retreat. The published margin on this reading runs ±1.39 ft/yr. Taken at face value, this segment's raw 0.49 ft/yr reading would land it 1022 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 1194 nationally for growth belongs to Point Lookout, NY, 1563 miles from this stretch, measured at 4.23 ft/yr. 1.9 miles away, Seadrift, TX is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Seadrift itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
