Sarita, TX Coastal Erosion Rate
What USGS measures 27.2 miles southeast of Sarita, TX
The coast 27.2 miles southeast of Sarita, 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.
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 Sarita, TX into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 27.05°N, 97.40°W. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
Where this fits nationally
This reading comes from 109 individual transects averaged together, 0% of which measured erosion rather than growth. The published margin on this reading runs ±1.62 ft/yr. Taken at face value, this segment's raw 0.45 ft/yr reading would land it 1008 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2004-1089. Chincoteague, VA sits at national rank 1119 for growth (1.09 ft/yr), one reference point among the 1211 scored segments, 1486 miles from here. 3.4 miles away, Sarita, TX is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Sarita itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
